An PWA primarily for my wife and my daughter. They can order their hot chocolate and their coffee as if they were going to grab something at a fancy café downtown, but instead it's at home and I'm the barista. It is quite nice to have for when my wife comes back from work and want something specific, or when we are waiting for the visit of a few friend, they can order exactly the available beverages and everything is ready when they're here.
It was also a good playground for me to implement Web Push notifications (to never miss new orders).
It's a basic Nuxt 3 app with Appwrite as the backend with rough edges, but much enough for our household use !
LOVE this. Are there any plans to open-source? I'd love to run my own instance.
Also some feedback: the ordering buttons are inexplicably in french despite everything else being in English. Choice of language or defaulting to English would be expected...
Also - multi-select and nullable options. So that I can create options like Taco / Steak / Pasta, and add side options that are relevant only when one of those is selected.
If there's a demand for it to become open-source, why not? But I'll have to improve code quality first. As the presence of french labels indicates it, i18n is not properly implemented for this project.
No, you really don't have to. Partially complete software can have a lot of value too.
Anyone can fork it and quickly add the i18n (or just translate into a different language) for their own purposes. People will likely want to contribute i18n. People may fix or improve things for you.
Of course, it's entirely up to you - but I've appreciated half-complete software countless times before.
Don't fall into this trap, strike while the HN iron is hot, all these people +1'ing will never come back when you're eventually happy the code quality is "improved"
If it's truly that bad you'll benefit from the feedback since it's an internet exposed service, although considering you're a professional freelancer, I'm sure it's fine.
It is far from fine. It was my little dirty project where I knew there was only 3 users and where I could be finally escape the usual process from my professional life.
But heh, now is the Time for me to patch all the hole I left. Lots of coffees depend on me now.
Si c'est open source je peux aider avec les traductions !
And yes, I feel like, working on it before open sourcing it is like cleaning before the cleaner. It's ok if the code is messy and there are bugs, that's why OS exist.
Bug report: I tried to create a new cafe with a name that contained a space character in it. The form told me the ID was invalid but seems to have created my user account anyway. When I log in now, the CafeID I get is 'undefined'; as in, I am now the proud owner of https://mytinycafe.com/undefined/barista. I'm assuming this is not intended :)
Just had a look at the control code. I must have been drunk because it is totally idiotic. I am surprised it took that long for it to be reported on HN
Very cool concept - thank you for sharing it! I think would be a great solution to the near-daily "what should we eat" problem.
If I could make a (not-important) suggestion, I think being able to re-arrange / categorize menu items would be useful. Something that lets you group together drinks apart from snacks as an example.
The "what should we eat" problem was a big source of tension in our household since the arrival of our first child. Too much time-consuming, too much planning effort. What changed our life (and I really mean it) is the app https://jow.com: it suggests you a list of meals for the week suited to your family and equipment, and it creates a shopping list for your preferred delivery provider. I only have good things to say about it and could go on for hours.
We're actually in a unique situation where the planning+buying isn't the hard part, but the deciding is. We're within walking distance of a super-cheap grocery store and I'm able to cook a wide variety of dishes - many of which I can make quickly. The hard part is my wife doesn't do well with open-ended questions like "what would you like to eat"? Seeing a discrete list of things I can make and her just picking/submitting the options would solve the problem.
Though that only holds while we have free time. If we have a kid, then I can see a great amount of value in that app.
I posted this in another comment but couldn't help but notice this discussion since it seemed relevant. I've been working on https://mealsyoulove.com, which is a meal planning app that also integrates with Kroger and Instacart for ordering groceries. Jow looks similar (not sure what their pricing model is?), but I'm leveraging AI to build highly tailored recipes and meal plans while allowing you to also import your own recipes to incorporate.
This is lovely,I thought about doing something similar but as a 'Dads taxi' app similar to Uber where my family can request rides. Partly because I sometimes struggle to remember where I supposed to be and when, but also because it might just be fun
Awesome! I like when imagination fills the gaps of technology, maybe because I played on old computers like spectrum, we had few pixels and had to imagine the rest.
The ordering could’ve been “solved” with a WhatsApp message, ( or shouting ? :D ) but that would have been so boring!
This much better life UX !
This app is a reminder of being playful and imaginative in life can bring joy, congrats!
You should add food and prices too. Obviously you don’t need to implement an actual payment system because it’s for fun, but if it kept track of the money, your kid could charge you 0.50 per drink or something.
Slightly disappointed to realize there is not some automated drink machine behind this, as that's more my interest, but cool nonetheless and you handmade drinks are probably better.
I'm working on porting KiCad to the browser. It's a lot of sweat and tears, multithreading issues and some more sweat. I've updated a port of WxWidgets and now I support all the features KiCad needs with ~200 tests.
Right now I have a build that loads in the browser, but I really want to have "multithreading" which means workers in the web. One can use asyncify with emscripten to translate blocking C++ to WASM, but that transition is not perfect, right now I'm debugging a bug where there's a race condition that halts all execution and the main thread runs in an infinite loop waiting for the workers to stand up. I guess I'll have a few of those ahead.
The main goal is to 1. just have fun 2. use yjs as a collab backend so multiple people can edit the same PCB. This will probably work with pcbnew, KiCad's layout editor, since it has a plugin system and AFAIK I can do the sync layer there. For the rest ( schematic, component editor etc. ) I'll have to figure out something..
KiCad does not sync automatically if you modify a file, I'll have to do some lifting there.
Anyway, it's a lot of fun, I really want this thing to exist, I'm hoping that I won't run into a "wellll, this is just not going to work" kind of issue in the end.
That's super cool! Not needing to install is great for accessibility for new users, and I think this would also be cool if it can be embedded into other websites as a viewer (like imagine opening up a Git repo with KiCAD files in it and being able to explore them in an integrated viewer)
That's a neat idea! To be honest my brain is overflowing with ideas too, right now I want to just bring all the apps one. Or... Actually just bring the layout editor up first :) I'm trying hard to live in the present...
I just finished a dsn parser and now I am planning to write a pcb router. All in rust. The plan is to have a wasm/wasi version as well so routing is possible in the browser.
Connecting the dots from agents to workflow automation to infrastructure with Taskade Genesis.
LLMs made it easy to generate apps. The harder problem is running them as real businesses. Where they live, remember state, coordinate agents, trigger workflows, and keep operating day to day. We treat the workspace itself as that layer.
One prompt becomes a living system. CRM, ops hub, internal tool, business in a box. Memory, agents, and automations working together. Feels closer to early web hosting than modern SaaS. Not demos. Real systems.
Still early, but builders are shipping real internal apps and workflows, not demos. Excited for the future of AI from productivity to agents and workflows to Infra!
On the subject of whisper being great... A few weeks ago a co-worker commented about the difficulty he'd had editing a work demo, I pointed at various jump-cutting tools that had automated what he did in the past (editing out silences). But I'd also wanted to play with whisper for a while...
So a couple of hours later I'd written a script that does transcription based editing: on the first pass it grabs a timestamped transcript and a plain text transcript for editing; you edit the words into any order you like and a second pass reassembles the video (it's just a couple of hundred lines of python wrapping whisper and ffmpeg). It also speeds up 4x any silences detected that sit within retained sequences in the video.
Matching up transcripts turns out to be not that hard; I normalise the text, split it, and then compare to the sequence of normalised words from the timestamped transcript. I find the longest common sequence, keep that, then recurse on the before/after sections (there's a little more detail, but not much). I also sent the transcription to ffmpeg to burn in as captions, because sometimes it makes the audio choppy and the captions make it easier to follow.
I know, tools have been doing this for years now. I just didn't have one to hand, and now I do, and I couldn't have done this without whisper.
That is absolutely awesome and I love hearing about the tools that people build themselves!
Honestly, the capabilities of whisper is insane, the fact that it's free and open source is really a gift. Some of the things it can do feels almost sci-fi.
If you ever decide to release it publicly please let me know, sounds like a very useful tool.
Couldn't find it on the Play store by searching for the name and the developer's name: if it is not just me then your app is very hard to discover.
So I am installing it through the link you provided, which directed me to a "install success" page saying "your purchase is successful" even if your app is free. Another obstacle to adoption :-)
Last, I was not informed on the page of the app' size. Seeing what it does and the time it takes to download I am afraid it could be huge? Third obstacle :-)
Thank you for the feedback, I really do appreciate you taking the time to check it out and write out the comment! I'll look at adding a note about total app size in the description, it won't hurt.
As for discoverability / the "your purchase is successful" message, I'm not sure what else I can do, I've set it to free, no ads etc in Google Play. Maybe I need to hit a few more keywords for transcription so it surfaces it more.
For me, searching for "whistle" on play store, I get the app as the third result (ignoring sponsored crap). Searching for "blazingbanana" gets me the app as the first result".
App info shows 218MB size, which I suppose is about what I'd expect for a model+app code :shrug:
Good to know, it's hard to know what real users would see in the play store and not Google just showing you what you want. Thank you for checking it out
That's very cool, I've been looking for a fully offline transcription app for quite a while. Thanks for building this! And thanks so much for providing an "import audio file" function, not just "record from mic" -- transcribing voice notes from various messenger apps is my main use case here.
Do you have an idea about supporting languages other than English?
The average model and upwards should support all languages from the whisper models by default.
I haven't tested them all so I'm unsure of the quality, however it should in theory support the following:
---
Albanian
Amharic
Arabic
Armenian
Assamese
Azerbaijani
Bashkir
Basque
Belarusian
Bengali
Bosnian
Breton

Apologies for the formatting, not sure how to make it look nice in the comment.
A new bugfix update for the "Translate to English" toggle (which was functionally always set to on) should be available soon, it's just awaiting Play Store approval.
I just tried running this on a 30 minute meeting with some 10 people in. It got to the end, then just bailed without transcribing. I also did not get any errors or anything.
Really sorry about that, longer running audio (~10m+) is something I'm working on along with handling multiple speakers.
I've been focused on getting functional parity across all OS's since the Android release. This is very close to being done and I just need to reach the milestone of it being available on all platforms before I move forward.
Hopefully you will take another look when the next update is out.
I really liked wisprflow on my mac but my daily driver is Manjaro KDE. I have stitched together a bash script that copies the transcription (right now I am using the Parakeet TDT 0.6B) to my clipboard. I would give this a try on linux when it becomes available.
Just checked out whisprflow, I must say that looks really nice, kudos to those devs. Shame there isn't a Linux / Android version.
I have added the auto-copy to clipboard functionality that will come with the next Android release and be included in all others. Adding a hotkey / quickbar button is on the roadmap for the desktop versions.
Would you be open to sharing your script? I run whisper.cpp in Linux through some stitched together scripts (https://news.ycombinator.com/item?id=44949314), but would be very curious to try Parakeet. I don't believe I can run it through whisper.cpp?
I looked at your script. I am doing basically the same thing just using onnx-asr (installed as a uv tool) with the parakeet model instead of the whisper-cli.
Look Here: https://github.com/istupakov/onnx-asr
Yes absolutely! I'm a GrapheneOS user myself so understand not wanting to have to go through the play store if you can help it.
I believe you have to make the source code public (please correct me if I'm wrong). I'm more than happy to do so, I've used a whole bunch of open source stuff to build the app so it only seems fair, I just need to make it a bit less messy and something I don't mind being public.
Focused on all the interesting and exciting happenings in tech here, from AI to defence to deeptech, and posting the most interesting job openings too. Did you know Europe had two space launch startups? I didn't until I started this project!
Color scheme is a bit harsh for me. I understand you're going for EU colours, but maybe a softer background like #fcfcfc and a more muted blue would be easier on the eyes?
Great idea, I'm keeping my fingers crossed for this initiative.
I believe that the main challenge would be to get more traction and build a community. Hope you find a way to encourage as many people as possible to join the website.
My very minor nitpick -- I would add some kind of background colour to the main post list, something like #FAFAFA looks fine to me.
Yes, absolutely! The guidelines for now are basically "same as HN, but Euro-centric content please" :) I'll write these down somewhere explicitly soon.
Ooh I like this! I love Hacker news and Lobsters but they're both very US centric, seem great to have a European one.
UI is very nice and simple, one tiny bit of feedback is that a 'guidelines' page would be worthwhile, especially while it's new! I thought I'd post my own project on the site - sometimes that's a little bit of a no-no though, and I couldn't find any guidelines to steer me towards what types of things to share, etc.
Edit: Tiny extra feedback, is upvoting something immediately changes the rankings in the browser. It's pretty impressive speedwise, but especially if you're a couple pages in, you can bump something off of the page you're on which makes it a little weird to do something like 'upvote article and then check the comments'.
Thanks for the feedback and posting, I appreciate it!
I'm definitely going through the comments I've had later and will take everything onboard. Guidelines is a great idea - for now it's basically "HN guidelines but Euro-centric content please" but I should definitely write that down.
Great initiative.
I was confused by the comment section design. The style of the metadata is not distinct enough from the real comment. And it tooks me too long to understand that the responses to comments were not citations.
You mean the automatic normalization HN does when you submit the title? Yeah, it's still quite basic compared to the real HN. I want to validate it properly before investing in lots of features :)
Interesting idea! I was kind of playing with the idea of doing something CrunchBase-like for the companies, jobs and funding rounds. But there's a lot of data out there publicaly too so I'm not sure if it's worth it. Will have a look at the HN clients too, thanks for the idea!
Ha, thanks for the feedback! People have made a few points about the styling, it definitely needs a harder look. Maybe a silly question but which do you find worse, the blue color or the underlines?

I'm building a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. We just won silver at the Big Indie Pitch competition as well!
- Currently in free Early Access with 18 competitive mini-games.
- Players use their mobile phones as controllers (you can use game pads as well!)
- Everything is completely web-based, no downloads or installs are necessary to play
- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!
- In the future we plan to open up the platform for 3rd party developers (and Gamejams!) as well. We take care of the network connectivity, controllers etc.. 3rd party devs can focus on developing cool multiplayer mini-games without spending an eternity with networking code and building the infrastructure.
Interested to hear if this resonates with Hacker News readers!
Thanks, you're absolutely right! The plan is to make individual game pages with little gif/video trailers and brief explanation of the different games but this is just something that I haven't yet gotten around to do :D
The platform uses WebRTC for connections so in the best case scenario (direct peer-to-peer connection): somewhere between 2-10ms. When direct connection is not available, 20-100ms. In really bad network conditions with VPN's in use: 100-300ms. Though usually the latency is not really visible in the games even if there would be larger latency with some players :)
Currently about 2,000 people play every day and I’ve released 59 puzzles!
One feature I’m excited about is crowdsourcing puzzles. Today’s puzzle is a “community puzzle” made entirely from clues that players submitted! I plan to do this every week or two.
I wrote about launching and the first month of puzzles if you want to learn more!
Thanks for this game, I've been playing it since you last posted it and it's become a regular in my morning brain wake-up routine of Minute Cryptic, Shuffalo at The New Yorker and a couple others, so I like the bite-size nature of it a lot.
I started playing a couple weeks ago (and got my Mum and one of her friends playing too).
I enjoy it, but I find the clues seem a bit too easy, and honestly I'm normally terrible at crosswords. Take that for what you will, totally understandable if you're aiming at "cozy/relaxing".
I appreciate the polish of the UI compared to a lot of the other janky word games out there anyway.
And thanks for the feedback! Balancing the puzzles is really tricky so it’s good to know when folks think it’s too easy or too hard.
It’s interesting to see the range of player skill (and how much they do or don’t enjoy challenge.) On a recent puzzle one player left feedback that it was too easy and another left feedback that it was too hard.
My aim is for puzzles to be challenging but not frustrating. The hard part is frustrating means different things to different people. From my stats I can see some players complete a puzzle in 2 minutes that takes another player 20.
For the daily puzzle I do lean towards making it a little easier but I want to explore a few ideas for making trickier puzzles in the future.
- Releasing additional “bonus” puzzles this are harder or more complex
- Letting people build and share their own puzzles at whatever difficulty they choose
- Adding settings to allow players to toggle things like hiding the theme at first.
That said, I’m still trying to figure out the overall balance for the daily puzzles! It’s good to know you think they’re a little on the easy side. I should try to gather more feedback and maybe tweak that!
I've been playing by just looking at the title of the puzzle and ignoring the clues. I can solve most of the puzzles that way, and it increases the challenge.
First time I see such a simple but attractive puzzle. I had to try to reproduce it using my Codorex tool, it's semi-functional needs a few more iterations:
I noticed it was added to a couple of others that I didn't submit to (goldles.com and dles.aukspot.com) I'm not sure if there are others I should be aware of.
I’m not totally sure! Marketing is not my strong suit.
I think my biggest advantages are:
- It’s sticky. A good percentage of players keep playing once they start
- Organic sharing. Lots of people have told me they shared it with friends and family. (I also built a “share” feature)
The pattern so far has been:
- I share it or someone else shares it somewhere.
- There’s a big spike of people trying it out.
- I get some new players.
- The player count stays roughly steady until it gets shared somewhere else that gains traction.
It was featured by Thinky Games. Sharing here got people interested. Someone shared it on Metafilter and that got a lot of views. Other folks have shared it on other sites that have led to smaller bumps.
My sister and I are glued to it, and she continues to destroy me, with consistent zero reveals and half the time to complete, as yours truly. We love this game. thanks.
I love UI animations but they can be overkill for a lot of web UIs so it was fun to have a playground where I could lean into that more. (Though I still ended up pulling back from some of my more “out there” experiments haha)
It started out as something marginally more useful than vendoring your dependencies as submodules + baking in the knowledge of how to build a bunch of common projects.
I realized, though, that there was somehow a huge gap in the insane world of C build tools. There's nothing that:
- Lets you pin really precisely and builds everything from source (i.e. no binary repository)
- Does not depend on either a scripting language or a completely insane DSL (Conan uses Python, CMake is an eldritch horror, ditto Make, lots of other tools of course but none of them quite hit the mark)
- Has a good balance of "builds are data" and "builds are code".
Anyway, it's going great. There are, of course, a ton of problems to solve. Chief among them is the obvious caveat that C is not a monoculture like Rust. There will be zero upstream libraries that use this tool natively. But I don't think it matters. I think I can build something which is as much better to the existing tools as, say, UV was to existing Python tools, even with that disadvantage.
I love programming in rust. Lots of non-rust developers think the whole point of rust is safety, but honestly, the things I like most about using it are the quality of life features like cargo. I love the idea of bringing that to C!
Relevant to this thread: I've spent the last week or so hand porting SeL4 from C to Rust, mostly so I can learn how it works (and learn OS development more generally). One of the biggest pain points I've had trying to use SeL4 is understanding the insanely complex way it uses cmake to compile the kernel and userland software. With Cargo, I can just run `cargo build` on my rust kernel project and it just works[1]. I don't even have a build.rs.
Anyway, I'd love it if we had a tool that made sel4 so easy to build. I doubt it'll be that simple, but its a lovely goal.
[1] (Well, except for one small step: You need to run objcopy to convert the 64 bit elf into a 32 bit elf to run it in qemu. But other than that!)
Sounds interesting and challenging. There's something similar, although not the build part just the modular aspect of it inspired by CPAN called CCAN: https://ccodearchive.net/. Very few people know about it, I believe, and it goes way back. I'm not involved with that project, though. Good luck!
Yup! But not in any state to be linked, really. First impressions are a big deal. If you’re really curious, my GH handle is tspader and the repo is spn. The graph branch has been the main branch for a month or so, I need to merge badly.
Thanks, it looks promising!
I built it and felt cargo-style - friendly and colorful.
Look like you really know what you do and what C community wait from such tool.
So, I leave my humble star on repo :). Good luck!
Me too! It's pretty good. Unfortunately, it depend on Python. Not that Python's that bad. It's just that it's completely bonkers to me that building C, the most fundamental language that's commonly written today, the language that every other language has an FFI for and three quarters of them either are written in or were bootstrapped with a version written in -- that this language depends on PYTHON to build!
It's crazy, and I understand why it's the case, but I know how to fix it and I'd like to have a crack at it.
Trivyn: Ontology-first knowledge platform. Runs on a single machine, via a single executable. I wanted a simpler alternative to the large complicated enterprise products that tend to dominate this space.
I'm really trying to get a private beta out the door by Christmas. I do plan to have a free version for academic/personal use.
Backend is written in Rust, uses oxigraph for its triple store.
I learned that ships have a "max load" line (or Plimsoll Line) https://en.wikipedia.org/wiki/Load_line_(watercraft) to prevent overloading them with cargos, but my todo list didn't. So I built an app to surface my emotional load and put mental health above raw productivity.
I am experimenting with the concept of giving each item in the iOS Reminders app an impact multiplier between -1.0 and +1.0 to assign them "weights". The net weight of the todo items should indicate my overall mood or emotional burden. If it doesn't maybe I have yet thought about what's making me feel good or bringing me down. The net weight is visually represented by the "water line" that rises the more into the negative the net weight becomes. I'm thinking of adding features to nudge me into addressing the rising water line.
And since I want to lower my own stress and anxiety using this app, there is no signup or subscription. No data collection other than the bare minimum to make the "tip jar" working through the App Store IAP, so no PII collection.
Do you think you'd find this approach to be helpful for managing your own anxiety level?
Love the idea! I was thinking it would be great if it could include a toggle that's kind of like the emotional version of selecting reverse y-axis in games (i.e. you can either push the controller up to look up, or push the controller up to look down) - you can either have the app show you tasks as how you see them. You could either use a view that has the more effortful/urgent ones in red, which may grow over time the longer you take to do them OR the tasks that cause you more anxiety to have a high blue capacity the moment you plug in the task and it reduces over time the longer you take to get to it. I guess my idea has a factor of procrastination that comes into play with the anxiety.
Thank you so much for taking a look at Plimsoll Line and giving such a good feedback! The anxiety caused by procrastination is definitely real, my wife and I both feel the stress when we see our devices spew the same reminders that have been postponed for many days (or months!).
The main thing that I would like the app to do is to nudge me to take small actions of visually surfacing the emotional impact of the individual items (a todo item or just a thought in my head) rather than them filling up my head. So I would like to be the one driving the app than the app driving me like most todo apps do. I want the app to help me break myself out of being paralyzed with anxiety by taking small actions that are doable and maybe even pleasant. Hopefully that makes sense when users try it. :)
So I'll have to think hard about how to solve the problems you mentioned, they are excellent points. Having fewer configurations and encouraging the user to take control of their emotions through small actions as core principles means some limitations in features...
Anyway, right now the app lets you write a "Quick Journal" into the Notes field in the Reminders app. I have in mind the app encouraging user to break down the items causing lots of stress into sub-items so it becomes more manageable. Or suggesting contacting a trusted friend that the user has selected in configuration beforehand.
Suggestions welcome on how else I can nudge myself and other anxious users! :)
It is a combination of a shoot-em-up and deck building. You fly and shoot until you get to the boss, when you get your deck out to fight them.
That genre combination is definitely too ambitious, but I think it is fun to play and I’m enjoying making it.
I have a bunch of ideas how to combine the two parts better. But over the years, I’ve learned to control scope creep and actually ship pet projects.
Right now I’m in a middle of changing how enemy waves are spawned. After that I want to make a short tutorial and add two more bosses as well as more enemies.
If you end up playing it, please share your feedback I’ll be glad to hear it.
The game is made using Kaplay, a game dec library which brings me joy to use. I can best describe it as my friend described Pico-8: “easy things are easy”. But compared to Pico-8, Kaplay doesn’t have virtual console limitations and comes with a big library of components. Try it out, the community is small, but the library itself is really fun and easy to use.
EDIT: For context, this is about two weeks of work, in the evenings when my kid is asleep.
I completely understand what you mean, I often feel like that as well. Like every other skill, it takes time and it feels frightening when you see other people's work. Honestly I don't think I'm that good at pixel art, this is my first pixel art project. To be fair, spaceships and technology are pretty straight forward to draw.
I’ve been working on a custom RTOS for Cortex-M for the past 10 years: https://github.com/raphui/rnk It started as a way to learn RTOS internals, and over time it has grown into something with lots of nice features. I’m even using it in a dirtbike anti-theft tracker I am building. Also, 2 months ago, I did a weekend challenge to build an embedded software parameter DSL and compiler. Its goal is to let firmware developers define configuration values, thresholds, constants, and other application-level parameters in a structured, human-readable format, and compile them into binary data that the firmware can directly use. https://github.com/raphui/epc
They compare it to timeshare systems, which seems horribly out of date (although apparently that's still kind of what occurs anyways on CPUs). What's the part that's "Real Time" relative to anything else people do with Cortex processors? The preemptive part? Not trying to be critical, just not getting the real time part. Does it not share CPU resources among tasks? Get a fixed core per task or something? Minimal interrupts and minimal thread switching?
An RTOS compared to bare metal just means it is some nice abstractions that you would expect from an OS : tasks, mutexes rtc.
An RTOS compared to an OS like linux basically just means it is deterministic, you can guarantee some interrupt is handled within a certain time. Not necessarily faster
The idea is simple, but I think it could be really cool: an autonomous agent that actually manages an entire radio station. It creates its own shows, play copyright-free tracks, shares the daily program schedule on social media and the website, and later I want to add guest appearances too and live 7/24.
I'm actually building this exact thing right now. Using Gemini TTS with its multi-speaker capabilities. Soundtrack comes from a Suno Playlist which the tool will download the entire playlist at the start.
Plays 3-5 songs prior to a "break", where the logic will call out channel donators vs pick a random topic to discuss, then use an LLM to generate the script before sending to gemini.
In the end; its really just a wrapper around FFMPEG broadcasting to an SRT or RTMP stream. I can upload the latest branch when I get home to share
that’s great to hear. I’d love to check out your project and have a chat if you’re up for it. maybe i can contribute to it instead of working on a separate project.
I am pretty sure 90% of playlists you hear when out and about are generated by spotify algorithms at this point. I would more be concerned because it seems like a weird use for LLM when recommendation engines are probably better than it? I suppose it has a ton of training data around music forums and people recommending songs, but it is hard to believe that would beat out billions of hours of tracked listening spotify has access too.
As bearish as I am on AI, outside of the agent deciding it only wants to play "Semi Charmed Life" and nothing else, I fail to see how this is a nightmarish hellscape in and of itself.
I feel standard commercial radio is already that hellscape. I mostly listen to rock (classic or alternative radio stations) and it's the same ~20 things being rinsed and repeated every hour and every day. Has been this way for decades.
I want to become a software professional, but I don't really know how I can do it. Focus on studying for many certificates or go to work or study at a higher level in school... Now AI is developing very fast; Claude can code very fast for every feature in my project, so I think I'm about to lose my job.
All the games were either developed with libGDX or threejs. I have no plan to monetize yet and still work on building traffic and improving SEO. Surprisingly, I got approved for google adsense already, which I submitted just for experimenting.
Working on a TUI tool which demonstrates the behaviour of X86 SIMD instructions. This is all done in Go assembly, and is probably most valuable for Go programmers.
The problem for me was trying to read and understand the implementation of a swiss map implementation. The SIMD instructions were challenging to understand and the documentation felt difficult to read. I thought that if I had an interactive tool where I could set the inputs to a SIMD instruction and then read the outputs, understanding the instructions would be much easier.
This turned out to be true.
Building this tool for all AVX/AVX2 instructions turned out to be a larger task than I had expected. Naively I just went off a Wikipedia page on AXV and assumed it had listed all the instructions (this was a bad assumption).
I am nearly there. Looking forward to completing this project so I can actually use it to do some fun stuff processing text and maybe even get back to that swiss map implementation.
I am running it in my city for a library of things. We hope to help people abstain from buying things they only need once a year.
It includes a reservation system, and an dashboard to manage those reservations in the shop. Currently I'm expanding it with a proper product management interface.
Here's a picture of the books we have and a couple of preview pages. You can put yourself on the reserve list. Tell you how long the current borrower, or the current "candidate for borrowing" has had the item, or had the possibility of borrowing.
What a wonderful project the Leihbar is! My local MakerSpace has something similar, but it’s pretty unofficial, you just have to announce what you’ve taken in a public chat.
I’ve often had the problem that I’ve needed a tool and borrowing it from Obi or similar cost more than half the price of a new one so I just bought a variant from Parkside for cheaper or similar price. Keep up the good work!
An interesting twist on this, would be to hold the used item while "paying" for it with a collateral. It would remove the need to have an owner to which the item must return to, allowing it to behave more like a linked list, reducing the amoutn of trips by two.
I also think that for taxeable purposes this would work better than buying and selling used items, especially in countries with gross income taxes. In the rest of the cases at least it would reduce the administrative burden to prove that ones net-income or value-add was marginal or negative.
Working on a new newsletter to encourage people get off social media by helping them discover all sorts of random interesting sites that exist out on the open web.
I don’t promote it. I have a blog. I let people know about the things I do on there. And if those people like it they might write or post about it. It’s just word of mouth.
But I also don’t really care about growth. I’m not trying to build anything massive. I just want to be helpful to people.
Thank you. I'm quite tired to see people insisting that the web is dead or is dying while it clearly is not since there's a lot of great content out there. But it is getting harder and harder to come by, that's for sure an issue.
Bedtime Bulb v2 [0], a light bulb that emits less blue light than other lighting, is finally shipping. It took years to get it right, but we figured out how to make a relatively energy efficient bulb that emits infrared and dims smoothly with any dimmer.
My team is also about to ship Atmos [1], a lamp for the bedside that automatically shifts from higher-blue light during the daytime to low blue light at night.
Very cool, what’s the temperature range/wavelengths? (good idea to specify it on the product page - otherwise it’s unclear how is it different from other lightbulbs)
The bulb ranges from 1700K to 2100K (it warm dims)
Atmos ranges from 1800K to 5700K
Maybe not the most obvious, but for both products, it’s in the tech specs under Quality of Light. We try to be very detailed with what we publish there. Thanks!
Indeed there are very detailed specs on the bottom of the page!
It’s not obvious because I didn’t get there - I expected it to be one of the expanding sections with “Product Details” and so on. (I.e. when you have expanding sections to start with, it’s standard that all the information is the sections, and users are trained not to scroll down).
very interesting. Can I control these with home assistant?
I already have a wind down dimming schedule on my entire home. It changes brightness and color temperature gradually over 2 hours. How do these bulbs compare with philips hue?
Yes, the bulb can be controlled with a smart dimmer like the Leviton model we sell on our site, or the Lutron Caseta plug-in dimmer.
These bulbs are not smart and do not have a full RGB array. But what you gain is way higher color quality even at low color temperature (1700K), much lower flicker, and infrared.
Atmos is a smart lamp, and we will get our Matter certification in early 2026. This one is also not RGB, but it has extremely high color quality in the whites and no blue spike. Flicker is lower and at a way higher frequency (32 kHz). We haven't updated the specs on the site yet as we are wrapping the calibration, but the CRI is 98 on the Atmos lamp.
It’s a combination of factors: you must reduce both blue light and intensity of light to avoid suppressing melatonin. Just reducing blue light might help a little, but it still suppresses melatonin. Melatonin levels and circadian phase shifts scale with total irradiance even if blue-depleted; basically, dimming the lights is really effective.
That’s why our products focus on both intensity and color change (but we lead with blue light reduction since it’s easier to grasp).
Also, if you look at our specs, you’ll see that we don’t use pure amber or red light; we use very low-blue white light with high color rendering. We have yet to do the study on this, but you can read surprisingly well with our lighting at a very low intensity (enough to make your mom angry that you are hurting your eyes), whereas with lower CRI sources, you would have to make them brighter to achieve the same visual acuity.
There is some emerging research that IR may play a role in melatonin production locally in cells, which is why we added it to the bulb. Early days for this scientifically, but Scott Zimmerman and associated researchers suggest wideband IR may be effective, even if it’s only 20-30% of the visible intensity.
Is it possible for the bulb to gradually lose brightness as the night goes on? The default of a light bulb being as strong as 4am as it is at 1am is certainly simple, but does not make for a good nighttime experience.
With the Atmos lamp, yes! It constantly makes very minor, imperceptible changes every few seconds. I also developed an app, currently in public beta, for Philips Hue that does this as well [0].
We're working on a Nest-style ML feature for the Atmos lamp that learns your intensity preferences and automatically applies them. And we have a whole bunch smart circadian products we're working on—something for the desk and workspace next.
For Bedtime Bulb v2, not out-of-the-box because it's all analog electronics, but we REALLY want people to dim it gradually throughout the evening. If you want to automate dimming, the Leviton Smart Dimmer we offer on the site will allow you to control it with any of the popular smart home platforms.
Why isn't Bedtime Bulb smart? Bedtime Bulb v1 was our MVP, and we focused on getting the quality of light right over adding any smart features. It turns out, many of our customers have told us they don't want anything smart. So when we made v2, we focused on doubling down on quality of light features: infrared, warm dimming, "Perfect Dimming" (smooth dimming with any TRIAC or ELV dimmer), really high CRI/R9/TM-30, etc.
Smart bulbs are definitely a future possibility, but right now, we have the analog line (Bedtime Bulb v2) and smart line of fully-integrated lamps (Atmos).
I built a free USCIS form-filling tool (no Adobe required)
USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.
So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.
I started a challenge I call “Dopamine Detox December” in which I stopped doing certain things to stop dopamine stimulants:
- No social Media
- No news
- No video streaming services (such as YT, Netflix, and Amazon Prime)
- No electronic and energetic music
https://meetlace.ai - LACE, a self-organising research companion for long-horizon inquiry.
With LLMs, generating ideas and snippets is cheap; what’s hard is keeping track of fragments with their “why I cared” context over months. Most tools (Notion/Obsidian/etc.) assume you will do the work (folder/tag/linking) structure will maintain it forever. I don’t.
In LACE we:
– capture fragments from the web via a browser extension
– auto-cluster them into evolving “threads” / projects with summaries & reading lists
– maintain a graph of connections across threads (“topology of attention”)
– let you turn a cluster of fragments into an essay draft when you’re ready to share.
Stack is a fairly standard web app + LLM pipeline. Used neo4j's llm-graph-builder as a starting point.
The interesting bit is self-organising graph. treating fragments/questions/lines of inquiry as first-class objects and letting the system reorganise around them over time instead of fixed folders.
It’s in a small test phase right now. If you’re a researcher/writer/engineer/founder who constantly loses good ideas in your notes and want to try something opinionated in this space, I’d love feedback.
Working on cargo like tooling for cpp. It just let you jump start a project for different build systems(vcpkg, bazel and meson). I am also planning to bring CLion features build on docker, ssh to cli with tui setup. Docker side is close to complete working on ssh for now.
I wanted to export long chats from Microsoft Teams but turns out Microsoft Graph API or some PowerShell scripts were necessary. API access is not enabled by our IT manager by default so existing solutions dis not help. So I built (vibe-coded) a browser extension for myself, then decided to open source it. There are still some edges to smooth out but it’s going fine.
Turns out it was a common pain point. Now it has around 800 users in Chrome+Firefox. Mostly chrome.
I'm working on Mutacortechs, an ALife simulation where "organisms" each have their own emulated 16-bit processor with 64K RAM. Like Core Wars for the 21st century. It's a small project compared to what some others here are working on, but it's an order of magnitude larger than anything this embedded EE has ever written. I have the ISA designed, assembler complete, emulator stage 1 complete (160/204 instructions implemented), and the start of the simulation working. Last night I wrote a program in custom assembly for an "organism" that looked around, found food, moved toward it, and ate it. I'm pretty excited by the milestone!
I launched this on HN over the summer, but it's millisecond-precise audio synchronization for multiple devices, performed purely in the browser! I'm sitting at around 5K daily active users now. Also, it's open-source!
ZenBot Stock Scanner https://www.zenscans.com One-man built and maintained stock scanner that finds stocks with relative strength to the market. It grew out of my early attempts to algo-trade stocks and has a solid community following. Front end is C#/Blazor, back end is a C# console app with intense parallel processing and data aggregation.
I’m self-teaching modern C++ by developing a native music library manager and player for Windows, macOS and other Unix systems. The main focus is on the 100% custom UI (with Direct2D/CoreGraphics/Cairo backends), aiming for responsiveness, power-user friendliness and compactness. The UI thread is absolutely sacred and I’m trying really hard to separate the core logic from the UI, because I hate how laggy and hang-prone all players I’ve tried are. I’m drawing inspiration from pre-2010 skeuomorphic and dense UIs. Key features include fast incremental imports and powerful UI elements with features like multiple column sorting, multiple element selection and keyboard-first navigation. I understand this problem is already solved, but I’m starting to DJ and curate my personal music library again. So far, nothing has been more satisfying than an old unsupported version of iTunes that doesn’t even support FLAC. I’ve tried foobar2000 but it doesn’t meet many of my requirements. Therefore, I’m building this software both because I have a need and because writing it is very fun (and frustrating at times)!
I’ve written a PoC already (mind the crappy and incomplete UI), mostly to test the wild custom UI idea, and it’s working so far! https://i.redd.it/ocx9m5av6d6g1.jpeg
The simplicity and density of that UI is nostalgic. You say it's crappy and incomplete, but all I'd want is a search bar which can actually scroll the whole-library view to the found-song (something I wish Spotify did, but they only filter.)
Okay fine, playlists are a good thing to have as well. Either way, I miss stuff this simple.
Implement them like the iPod used to implement playlists. There's no playlist bars, tabs, UI, or other clutter. You just had a default list you were working on, and anything you added got added to it.
Except for the constant glitching and crashing, the iPod had a really great user interface. (and to be fair, that was probably partially my fault for downloading all kinds of sketchy MP3s)
Lineage-aware. Versioned. Trustworthy Data - for Engineers and AI.
Your engineers waste up to 40% of their time monitoring, investigating and fixing data. Even then you don’t trust the accuracy, source, or freshness of metrics on your dashboard. You wish AI can answer your data questions but it cannot show you proof, or where it came from. AI helps software engineers to move fast and break things, because they can always rollback, with git. But you cannot do that for data. Bad data entering the system, spreads across the company before spotting, and takes weeks to clean up.
DV changes this, giving you lineage-aware, versioned data. It records data-lineage when data is captured, transformed, and committed, at commit/snapshot level. So when things break, DV knows what other data is impacted downstream, and it can rollback the whole chain to the previous state, instantly - no data copy/restore needed. It can also backfill the data across the chain automatically.
With DV, both your team and your AI agents can finally see:
- where data came from
- how it was transformed
- how to revert safely with a single click
Your engineers can move fast on data, without breaking trust. Your analysts can build pipelines by simply describing business questions to AI.
DV is Git for data, so you can focus on your business, putting analytics on auto pilot.

Want to put local history on a map, so when I go somewhere I could ideally just open this webapp and immediately get presented with cool or interesting history that happened close by.
Currently spending time establishing relationships with historical societies, as I really need them to contribute points of interest, and stories. Many of these societies are run on a voluntary basis by 70+ year olds, so it's a long process. Getting some good responses eventually though, so it might actually go somewhere, just a lot slower than I want.
Also still doing https://wheretodrink.beer, but haven't added anything of note since playing on this other project.
Oh, thanks for the interest, but I'm not that far along yet. I have a bare bones alpha, but it's not ready for the internet just yet. I also haven't secured the domain names so I won't be sharing any code names :)
This is so very silly, but the only way I have to collect emails for people interested in the progress, beta testing or final version, is on my beer page.. So I created a page for the world's most obscure / smallest city and if you want to be updated you can register there - https://wheretodrink.beer/in/croatia/hum-75gkn - The registration is under "Stay informed about updates in Hum?"
If anyone signs up I'll manually move you out of that list and into the "local history" waitlist.
I'm working on a postcard maker for museum collection artworks in the creative commons. It's in a phase where I'm looking to get feedback from people who might like to use it. Right now it only sends mail in the US. I've integrated the Met, Cleveland Museum of Art and AIC, with an experimental feature for Wikimedia Commons.
Camera2URL is, as far as I know, the only iOS and macOS application that let‘s you send the picture taken with the camera directly to any HTTP endpoint the moment you press the trigger.
For example, this makes it possible to trigger an n8n workflow the instant you take a photo:
Still very early stages, just put the site together a few days ago: Veform https://veform.co/
iOS/JS/Android Libraries for turning traditional inputs/forms into audio conversations.
Have everything working and am happy with how the underlying data structures came out.
It is interesting because where I ultimately landed there is just an additional "state". So there is a UI state (Browser managed DOM), your app logic state (consumers manage), and a conversation state. The library just exposes events so you can keep the conversation state in sync with your other states. I started out visualizing a direct like: <form/> as a conversation flow, but you could configure it to navigate pages, click elements, or whatever through audio conversation.
I'm working on an affordable SaaS platform for small and mid-sized fabrication shops across the US and Canada. It automates quoting and production for sheet-metal and CNC jobs and can handle pretty much any CAD format, even full assemblies. On the AI side, we've got a mix of models doing the heavy lifting: a tuned geometric transformer for feature detection, a graph neural net for topology, and a vision model for mesh segmentation. All that ties into our custom CAD logic for geometry parsing, 2D nesting for laser/machining, and 3D nesting for forming and packaging. The whole idea is to level the playing field so smaller local shops can compete with the big instant-quote guys without needing an in-house dev team.
Is is essentially a SaaS version of what businesses like OSH Cut and SendCutSend have built? And are you doing just the quoting, or full shop management?
That's exactly what it is. But instead of keeping it as some proprietary tool for one shop, our goal is to make that same tech accessible and affordable for all shops. Not every fab shop is tech-first, and that's totally fine. We're building something that helps them compete without needing a full-time developer or a six-figure software budget.
As for your last question, we're not trying to replace any existing ERP or CRM systems. We're focused on delivering instant, accurate quotations through our own turnkey pricing model that helps job shops stay competitive day-to-day, manage payments seamlessly, and give customers real-time shipping options or an easy Will Call pickup if they're local.
I can't tell how you allow the small shops to make instant-quotes. Is it because they can instantly visualize the part? Or do you process the customer's design and provide the shop additional information that helps them do this? Or are you just generating the final quote itself already based on what you know about the shop and the customer design?
Good question! Right now we’re starting with the sheet metal side of things: laser cutting, forming, welding, surface finishing, and final touches like anodizing, powder coat, or just a clean mill finish. The platform takes the customer’s CAD file, runs DFM checks, figures out material usage, laser time, bend complexity, and weld length, then instantly generates a production-ready quote based on each shop’s own pricing and capabilities. This quote includes delivery cost + an estimated time you can expect the part. There’s 2D and 3D visualization built in, but the real magic is the drag-and-drop, get-an-instant-quote experience. The reality is, most fab shops are still painfully slow when it comes to quoting. Even in 2025 it’s not unusual to wait a week (or three) just to hear back. That’s the gap we’re closing.
Very interesting. The big followup question is to ask is: Currently shops spend X% of their time creating quotes and talking to incoming customers, and (100-X)% time actually doing the work. What is X% for a typical shop and how much are you hoping to reduce it to?
Based on industry data and first-hand experience, most small to mid-sized fabrication shops spend 25–40% of their total time on quoting-related activities: reviewing customer drawings, clarifying requirements, preparing cost breakdowns, and going back and forth over email or phone. In some job shops with limited staff, quoting can even eat up half a workweek for the owner or lead estimator.
Our goal is to bring that number down to under 5% by automating geometry analysis, material costing, and lead-time estimation. Essentially turning what used to take days (or weeks) into an instant, self-service process for customers. That frees up the shop to spend the remaining 95%+ of their time doing what actually makes money: fabricating parts.
No, we aren’t using any CAD software for this since we’re not trying to be in the design space ourselves. Instead, we’re using libraries like OpenCascade’s Mesh Toolkit to read and tessellate CAD files into a hybrid 3D format optimized for web rendering, while preserving precise geometry, topology, and manufacturing data.
Making a first aid kit for stingray stings! If there are lifeguards nearby they’ll usually treat you, but we think it would be nice to have a “go bag” in the back of your car for scenarios where there aren’t lifeguards (remote beaches, or after sunset, etc). The standard of care is to clean the wound and submerge it in water around 110-120F for 1-2 hours. We’ve been researching the best, safest method to get that heat, and working on putting a package together. Here’s our first attempt:
I actually doubt that. Irwin was a philanthropist and a scientist, with a decent sense of humor. This is a basically profitless project for public good. I think if the founder has bona-fides, Irwin’s estate would jump at it.
Hmmm we've never approached the Irwin estate, even though all our work is about stingray sting prevention and treatment. We do need to make profit to stay in business, so it's not entirely charity. Maybe we should see how they feel though. I also worry about the optics of advertising so directly on somebody's death. Especially because none of our products would have prevented / helped in his scenario.
A personal photography website for myself using a bunch of AI services to enable automatic tagging, color extraction, and hopefully some novel discovery methods.
I really like the color discovery features - I wanted something like this to exist when I was trying to find prints for my house with specific color harmonies.
I just moved to a house with a barely finished basement. White walls, white painted floor, exposed ceiling joists and ductwork painted black. I’m experimenting with cheap projectors and lighting effects (using clamps to attach to the joists as if they were a truss) and furniture on wheels to create a configurable virtual space with full wall projections, sound, and lighting to match (but not overpower) the video. My plan is to make a camera/light platform with a cheap projector, and Raspberry Pi, and directional LED lighting so that I can coordinate all of them over the network. It’s also my office, library, game room and I have some awesome ideas on how to use the space to augment D&D games. But the white concrete floor has got to go - too bright, too cold, too hard, and too loud.
I'm working on a Unicode visualization tool [note 1]. It's meant to visualize transformations and relationships between characters, as well as connect everything directly to the exact lines in the Unicode Character Database (UCD), which defines these relationships. The UCD is a series of text files, it also has an XML version.
I love online Unicode tools, serious ones and silly ones, and I use them often for fun or for development. What I see online is that few technical people have a good understanding of Unicode, or have big misconceptions about how it works. I'd like to change that, through visualizations and direct links to the data sources (the aforementioned UCD) and links to the Unicode documentation (which is well-written but can be difficult to navigate or even find).
I've worked a lot on it, but I'm totally stuck again. I get too zoomed in and it's hard to see the big picture, plus it's difficult to know how much effort I can realistically put in because I don't know how big the market is. It's a niche tool, but how niche? Would anyone pay for it? But I'm not sure how to do market research, especially for a niche like this. Any advice would be appreciated!
I'm writing a toy eigenvalue solver in Rust using the QR algorithm.
I didn't intend to, but I recently discovered the Gershgorin Circle Theorem and thought it'd be neat to create an interactive visualisation for my [blog](https://abstractnonsense.xyz).
I don't like JavaScript, and I've been meaning to learn Rust for a while, so I'm compiling the Rust algorithm to WebAssembly to run in the browser natively! It's been a fun trip back into the arcane world of numerical algorithms and linear algebra!
It's edge native (with a Cloudflare deploy button in that repo) with your posts stored in an SQLite file. You can log in to your site to post and comment on your own posts, and use a web extension to comment on posts from people you follow wherever they are on the web.
There are many bugs and missing features, the documentation is patchy, and it's probably riddled with security holes. Give it a go if you're feeling brave!
I'm currently making a number of "breadboard-able" analog computing modules.
I've always loved electronics since I was a kid (still trying to learn). As I explore and learn I've begun to make these small "breadboard helpers" [1]. (Just one on Resistor Transistor Logic (RTL) right now.)
An obsession over a project in a 1970's hobbyist electronics magazine sent me down the rabbit hole that is (was) analog computing. So I have been bread-boarding and prototyping small analog computer modules.
I'm in the PCB-layout stage for the modules and hope to have them ready early next year.
I've been slowly building a website full of daily puzzle games (https://regularly.co/). I built the first game for my wife (https://regularly.co/countable) which she plays every day. Floored is my personal favourite, I find it deceptively challenging
Is there any way (e.g. paid subscription) to have access to all of the puzzles (all past history)? E.g. I'd love to be able to play all the past Kingly puzzles.
Sadly not at the moment but it was always the plan to eventually allow playing of the catalogue - I'm still unsure as to whether I'd choose the subscription model.
This is actually pretty much as done as it's going to be (could use some nicer UI feedback, i.e. how you actually use the app) - it is actually just a demo for an effort I undertook to mod Datastar to support nested web components. I am writing it up as we speak!
Instructions: you have to answer three questions; each one will auto-submit once your response goes over 100 characters; the answer to the third question is your "post". It's a proof of concept of a friction intervention for social media to encourage slow thinking before posting (and hopefully reframing negative experiences in the mind, it's kind of dual purpose).
I’m working on a deterministic execution layer for AI systems.
The idea is to treat LLMs as constrained components inside explicitly defined workflows: strict input/output schemas, validated DAGs, clear failure modes, and replayable execution. Most “AI unreliability” I’ve seen isn’t model-related — it comes from ambiguous structure and hidden assumptions around the model.
We’re exploring this through a project called FACET, focused on making AI behavior testable, debuggable, and reproducible in the same way we expect from other parts of a system.
Still early, but the goal is simple: less magic, more contracts.
Purposefully not building software but cold calling 100 businesses in my niche. Starting at 1 call per day for 10 days, then 2 calls per day for 10 days, then 2 conversations per day for 10 days, and scaling up until I reach 100 calls. Exposure therapy as well as product discovery wrapped in one.
Thank you for the feedback and your suggestion! A (partial) correlation network with Cytoscape.js is planned as one of my next experiments. A former colleague nudged me in that direction just a few days ago, and now you as well, so I'll probably have to build that next.
Building pyreqwest, a high-performance Python HTTP client backed by Rust’s reqwest. It has gotten quite feature rich: async and sync APIs, similar ergonomic interface of reqwest, full type hints, and built-in testing/mocking. It has no unsafe code, and no Python-side dependencies. (Started after getting too annoyed with all the issues httpx has.)
I've recently updated an internal tool which basically acts as a configuration and dependency/context manager for performing hundreds of api calls. I added an httpx backend (to test vs the current urllib3 backend) and also introduced an async API (httpx as well). However, from your benchmarks it seems like I should've went with aiohttp for faster async? I will work on integrating pyreqwest as well
Yes httpx is badly broken. Eg its connection pooling implementation is not great at all. There are various issues in httpx/httpcore. There are also old open PRs trying to fix issues but maintainer(s) are just not intrested.
Infrastructure architects think in terms of building blocks in "high-level designs" and those building blocks are often socialised/expressed in Visio/Spreadsheets. Thinking in building blocks is now more necessary than ever because of the sheer size of the infra being designed/deployed.
This approach is problematic after the design phase because there's a lossy translation to where the low-level design lives, often referred to as the Source of Truth, like NetBox.
NetBox Designs allows users to express composable, versioned, and templatizable building blocks that can be rendered to low level designs. No lossy translations, and you can always check in the future "does my LLD still match my HLD and if not, where?"
I've been building Hypertrophy, an iOS-native workout app. I've always wanted a simpler, cleaner experience than Strong (on which I've done over 1000 workouts) so I built my own.
I've tried to make it look and feel at home in iOS and I like to think of it as a Notes app for the gym—it does very few things and does them well.
It's completely free with no ads because I'm not a fan of how other workout apps charge you for a basic workout experience.
I've just finished up the Import from Strong feature and would love any feedback on it!
1. Vibe coding a microcontroller firmware project. I'm using "vibe coding" in jest here because I'm actually an experienced coder, but this was a chance to try using the AI coding assistants for a clean sheet project at minimal risk. I'm going on 63, and could easily finish my career without AI, but where's the fun in that?
One amusing thing I've noticed is that every time the AI generates code with a hard coded hexadecimal constant, it's a hallucination. My son suggested feeding all of the chip datasheets into the AI and see if the constants improve.
2. Finally converting my home semi-hobby electronics business (something like a guitar effects pedal) to machine assembled circuit boards.
I was thinking about FizzBuzz and thought it might be cool to benchmark various LLMs to see the highest number they could go before they got it wrong. FizzBuzz is cool because you can test whether the model's can generalize to any other game (divisors of 3 and 7 instead of 3 and 5 for example).
Fun, short and sweet experiment to run over the weekend, with some mildly interesting results :)
I’m building PaperDrop it's a research workspace that turns PDFs and new arXiv papers into something you can actually work with (notes, questions, cross paper comparisons). Would love feedback from people who read a lot of papers: https://paperdrop.xyz
It's still early prototype / beta, but wanted to share it anyway!
I have just released a map of median rents in Berlin [0]. Now I'm improving it. I want people to enter their search criteria, and get an idea of how rare and expensive their desired apartment would be.
This will help people set clear expectations for their apartment search.
EACL (Enterprise Access ControL) is a situated ReBAC authorization library based on SpiceDB, built in Clojure and backed by Datomic. EACL queries offer sub-millisecond query times and has replaced SpiceDB at work (CloudAfrica).
'Situated' here means that your permissions live _next_ to your data in Datomic, which avoids a network hop and avoids syncing to an external AuthZ system like SpiceDB, so all queries are fully consistent.
EACL is fast for typical workloads and is benchmarked against 800k permissioned entities. Once you need more scale or consistency semantics, you can sync your relationships from Datomic to SpiceDB 1-for-1 in near real-time because there is no impedance mismatch between EACL & SpiceDB.
IMO, if you need fine-grained permissions, EACL is currently best-in-class for the Clojure ecosystem. EACL is especially suited to Electric Clojure applications and can be used to populate menus in real-time.
EACL would not have been possible to build solo in my spare time without modern AI models to rapidly implement specifications and test against human-written tests.
Simplification of my digital self. Removed most of my online accounts. Removed all my VPS's. Removed most apps from my phone except core ones. Cancelled a lot of online subscriptions.
In the real world finally moved everything to USB-C. Gave all my old cables away. I have two chargers in my home and a handful of C to C cables. Everything connects to everything now.
Home is now downgraded to a dumb home. Lights work on physical toggles. No hubs or sensors anywhere. Heat and AC is with a dumb panel on the wall.
I did a similar thing a few years back, but rather than simplifying, I focused on getting rid of hacky DIY things that needed maintenance.
I got rid of almost all the customized software in my life, and the few projects I decided to keep, I aggressively modernized, getting rid of thousands of lines of original code and adding many times more tests than I'd ever had before.
It very significantly improved my life and career to not have a second part time job maintaining a note taking app.
With off the shelf options, preferring FOSS if possible, I still enjoy using and contributing to open source.
Some of the substitutions wound up being a step down in features, or required rethinking parts of workflows, but the time savings is such a benefit.
Custom notetaking tool with p2p sync-> Google keep
Custom batteries included Linux distro for SD protection, Kiosk browsers, offline docs, creative commons content packs -> a few scripts built into my control server on vanilla RasPi OS
Rsync-> Borg -> Kopia(to avoid fussing with Borg's community NAS package)
It was a lot of micro-USB and some Lightning. CAT5E and lower. HDMI 1.4 and lower. All still useable cables for many people. It went to my local hackerspace.
For me, it’s always having website productivity blockers on all my browsers across all my various devices (and for the most part, not installing news apps on any devices either). Haven’t simplified my digital life, but at least it’s very restricted. Yeah, if even one device doesn’t have one installed, feel like am vulnerable to having hours sucked away.
And actually, still browse the web and watch YouTube, but just on my non-work days.
I had a lot of hobby projects. Some home automation. Some would scrape websites for archival purposes. Maybe a seedbox and an arr-stack. Total monthly cost of a bit over €60 for all of them. Didn't really add anything to my life and the upkeep took about an hour every month, even with auto-updating as much as possible, sometimes things broke or required manual updating (+migration).
None of them were open to the public, I SSH-tunnel into them. All stuff just for myself.
I backed everything up locally and shut them down. They should be auto-removed at the next billing cycle.
https://pistepal.app/ - a ski map app - built at breakneck speed over the last few months. I believe this is the only ski map app that offers turn-by-turn navigation!
Still a little bit rough around the edges but hopefully will be / is in decent enough shape for the start of the ski season (just about happening now..)
Currently figuring out the right balance of free tier & daily trial. Priced at $10/month and therefore significantly undercutting the competition, hopefully this is enough to gain entry into the market. (May need a more generous daily trial though, admittedly 10 minutes is not really enough to actually try it out on the mountain).
Seems ad spend is necessary to get any kind of traction...
Yeah very specifically above or below. You don’t need to share exact location data (although you’d still need access to it on the local device) - just elevation.
Don’t over engineer it - just an indicator about how much further down the slope or back up the slope the rest of the pack is.
I find it annoyingly frequent that I’m either waiting for mates who have bombed off ahead because I didnt see them pass, or I’m waiting at the bottom for mates who are up the slope waiting for me because they think I’m behind ! Literally hours wasted each trip doing this.
You might think a quick phone call is the solution to this but that’s too clunky. It’d be nice to take out my phone and just quickly see something on the home screen indicating this, or on the watch app.
Would also think about ways in which the app could indicate the elevation of others without having to stop, remove the gloves, picking the phone from my pocket, looking at the screen, and putting everything back on every time.
Maybe having different kinds of (infrequent) beeping in specific cases:
- when I'm last
- when I'm first
This could get old quite quickly thought, just a thought.
That's a great idea. A lock screen widget could work really well here, showing the relative elevations of your buddies. You'd have to take your phone out - but you wouldn't have to take your gloves off!
The core simulator part works, but I don't yet have a user interface or documentation. Probably just going to be text input files to start, maybe a GUI later. Recently, I'm mostly working on testing.
The simulator is object-oriented and basically allows one to build up a blaster from separate control volumes and connections between control volumes. This is useful as it allows the same core simulator framework to handle different blaster configurations and even variants of them. For example, someone asked me to make the spring piston able to pull a vacuum on its back side due to not having sufficient flow. That's easy here as I just need to add another control volume and the appropriate connection onto the basic springer configuration.
Some months ago, I saw a tweet from @awilkinson: “I just found out how much we pay for DocuSign and my jaw dropped. What's the best alternative?”
Me being naive, I thought “how hard could would it actually be to build a free e-sign tool?”
Turns out not that hard.
In about a weekend, I built a UETA and ESIGN compliant tool. And it was free. And it cost me less than $50. Unlimited free e-sign. https://useinkless.com/
If the tool doesn't adhere to those standards, the resulting signature isn't legally compliant (at least, not in a way that satisfies corporate structures).
What does legally compliant even mean here? I can print a document, scribble on it with a pen, and scan it and that's legal, so how high can the digital bar be?
SecurityBot.dev is an all-in-one uptime, performance, security, and SEO monitoring tool. I launched it a few months ago and have been iterating on it ever since. Later this week SecurityBot.dev will log its 1 millionth uptime check which is pretty cool to see.
It includes the usual uptime monitoring service that you see everywhere else, but also features such as a PageSpeed Insights monitor (https://securitybot.dev/pagespeed-insights) and a broken link checker (https://securitybot.dev/broken-link-checker). I continue adding new monitor types as I personally need them (and also based on use feedback).
Trying to build a small-scale ISP/hosting provider domiciled in Canada. We really want to be able to rent real rack space to enthusiasts who would like to benefit from having stuff in the datacenter but don't want to take on the opportunity cost to get started. It came out of my own desire to have a machine in a DC rack.
This week we've been writing a bunch of "reviews" of self-hostable software since a lot of our friends are curious about this space but don't have a good understanding of how to get started. https://blog.colocataires.dev.
Your VMs are a bit pricier than some other larger services located in other parts of the world - which I understand. I hope you are able to scale to the point where you can lower these prices.
Are there any legal or other reasons I, a resident of Canada, should host my services in Canada rather than in Europe or US?
I'm currently working on something that lets you describe a hardware product in plain English and get actual manufacturable files out — PCB, enclosure, firmware, the lot.
Very early days still. Whilst I created a fork of toon for Kicad (called TOKN (https://www.mikeayles.com/#tokn)), with the intention of using a reduced token format to generate schematics using LLM's, I could get the models to follow the syntax correctly, but they didn't have the knowledge. So I was then going to create a whole RAG system, but got distracted by this current project.
There are people out there doing AI schematic generation, like flux.ai (which is incredible (and incredibly well funded)), but 90% of products, especially at proof of concept stage, are basically a microcontroller, some power, probably usb, and some IO, bluetooth/wifi if you're lucky. So we can use a library of pre-validated subcircuits and slots them together on a grid. Routing's deterministic, so if it compiles, it works. (sorry, deeppcb & Quilter!)
The enclosure side is more fun: once the PCB's done you've got real dimensions to work with (board size, mounting holes, where the connectors poke out), so I use an image model to generate some concept art, then feed that to an openscad generating model as visual inspiration alongside the hard constraints.
Basically trying to get a full hardware product pipeline done automatically.
Building a simple service that allows one to post live activities to mobile devices (iOS to begin with).
It started as something I wanted to build for myself. I have a Bosch dishwasher that lacks any glanceable indication of how far along it is. Bosch provides an app, but checking the progress takes too long to be useful.
I figured live activities was a good fit, and then realized that I am not alone in wanting something like this. So, I am trying to make it into something usable for all the home automation tinkerers.
Love this, I'll keep an eye on it. I'd happily use it with my apartment building's clothes washers, which are connected to the internet via a painful UI.
Amazon used to have a thing for books that didn't have Kindle editions, "Click here to tell the publisher you'd like to read this on Kindle." You should develop in public (X/Bluesky/Mastodon), and have a prominent form for wonks like us to forward "I want Aivi" to various manufacturers.
I'm writing https://github.com/controversy187/kerbalbook, which aims to be a hobbyist's guide to orbital mechanics, spaceflight, and maybe astrophysics. All this through the lens of a Kerbal Space Program walkthrough.
A prompt engineering tool that takes vague prompts and transforms them into context-rich JSON/XML structured prompts. Fully customizable and tracks prompting history safely in tab session, automatically injecting context and learns style.
Makes outputs of any AI so much better due to restructuring and breaking down requests into instructions AI can easily execute upon and mitigating risk of hallucinations. Perfect for complex tasks like coding and content creation.
Exists as a free chrome extension right now. Would love if you tried it and have any feedback!
Open sourcing a system where you might have notes in markdown to build a knowledge base, and review them according to a schedule, but also Anki like flash cards attached to each note.
All notes are simple markdown file stored locally.
I’ve been using it to benefit my research and make the knowledge to stick better on my head for several years. My base is more than 400 markdown notes now, and I sync them to a private GitHub repository.
Since hacker news last saw it, it’s been translated into English, German, Spanish and Chinese. If, say, a Chinese speaker wanted to learn more English words, then they could go to https://threeemojis.com/zh-CN/play/hex/en-US/today and play the game with English words with Chinese definitions and interface. This is the first cross language daily word game of its kind (as far as I know), so it’s been a lot of fun watching who plays which languages from where.
The next challenge that I’m thinking about is growing the game. The write ups and mentions on blogs add up, the social sharing helps, but I’d really like to break into the short form video realm.
If you read interviews from other word game creators, every successful game has some variation of got popular riding the wordle wave, or one random guy made a random TikTok one time that went super viral, and otherwise every other growth method they have tried since then hasn’t worked that well and they are coasting along.
So, sans another wordle wave, I am working on growing a TikTok following and then working on converting that following into players, a bit of a two step there, but that’s how the game is played these days. https://www.tiktok.com/@three_emojis_hq for the curious. Still experimenting and finding video styles and formats that travel well there. Pingo AI and other language apps have shown how strong TikTok can be for growth, so I think there’s something there. That’s all for this month!
https://craftcx.com - Working on various aspects of trust and observability around the performance of AI Customer Support tooling.
How's the support agent performing?
Are the resolutions you're billed for "good" resolutions, or just deflecting the customer without helping?
Working on migrating Hopp's [1] overlay window, which we use for drawing the remote cursors, from winit + wgpu to gpui. I used claude in the weekend to make a prototype and now I want to make a gpui app, which will replicate all of our requirements, in order to see what is missing and if I need to contribute upstream. I am planning to write a blog post when the migration is over.
Making a totally unnecessary and overly elaborate magic item system for my game https://www.chesscraft.ca based on Diablo 2 items. Is it the most reasonable next thing to do to expand the business and monthly revenue? Hah, no.
But unlike my day job, this is my project and I get to do what I want. This is my code therapy.
Just launched a restricted browser for kids for iOS: https://weblock.online
Now testing on my kids. The idea is that the browser is whitelist-only, so kids can open only approved websites. I receive a notification when they want to visit an unknown website and I can allow or deny it.
Works great for my family, hope it will be useful for someone else.
How does it work on a more technical level? I would be interested in seeing a bit more tech detail, perhaps because I'm more technical, but also there's so much competition in this space that you need something to differentiate.
For example, is the blocklist UX side Domain based? Company based (Allow all by Google/Alphabet), category based (Search engines)?
And on the backend, is it DNS based or HTTP based? Or maybe an OS hook.
Weblock uses a whitelist, not a blacklist, and it is domain based. Once you allow a domain, it can be browsed by a child. You can allow it forever/15 minutes/1 hour.
How it works: WKWebView, before loading a page, asks the backend if the domain is allowed. If not, it shows "Not allowed" screen and a "Request access" button - child can tap it and you (parent) will get a notification.
So traffic is not going through the backend or a filtering VPN, the app just asks the backend if a page (domain) is allowed to visit.
Visits are logged, so you, as a parent, can see what your child has been browsing. How much time did he spend on a homework website.
Some WKWebView callbacks used for that:
* onShouldStartLoadWithRequest - to intercept a request and check if it's allowed
* onLoadProgress - to show loading progress bar
* onNavigationStateChange - to track browsing history
Also I had to implement a workaround for buggy Screen Time in iOS 26 - even if you add Weblock to "always allowed" apps, iOS will still treat each website as a separate "app" and block it, asking to you "allow' each website on system level. It happens inside WebKit codebase, but luckily this bug has another bug in it - if you re-open a website, it suddenly works and all other websites in this session work tooSo I need to listen to `onScreenTimeBlockingStateChange` event and automatically reload a website if that happens.
Also I added an ad blocker to Weblock. It uses uBlock Origin filters, converts them to WKWebView content rule JSON format and feeds to WKWebView. The app checks the backend if rules are updated and updates a local copy.
What's next: need to get "Default Browser" entitlement from Apple. Then you can block Safari on kid's phone using Screen Time and have Weblock open all HTTP(S) URLs.
App is written in React Native, no performance issues. Backend is Ruby on Rails.
I’m building something that keeps finding gaps I didn’t realize were gaps.
It’s called Riftur, a gap analysis tool that compares two documents and highlights gaps, missing requirements, and inconsistencies. The interesting part for us has been getting the system to understand intent instead of just keywords, so it can flag partial matches and subtle gaps rather than just “present / not present.”
Still early, but it’s been useful in ways we didn’t fully expect. If anyone’s curious, you can demo it out here: https://riftur.com
I'm happy to hear thoughts or learn how others handle this kind of review work.
A place to find and be found for twitter users only right now. As a silly project I am trying to make not a social network, but an extension of another social network. So far its going OK. It also functions as a link-tree like site with profiles: https://meetinghouse.cc/x/simonsarris
Eventually I might open it up more widely, or make a different globe per social media network.
For the past week, I’m working on creating device with a screen to show my indian parents if i’m in a meeting or not. So they don’t trouble me and come in my room unannounced when im in a meeting.
It’s build using ESP32 and a small screen which shows On and Off and the time till meeting is over. I learnt Fusion 360 and designed a small snap fit case and got it 3d printed.
I have a small electron app running in my mac os system tray which connect to esp using BLE and it also checks if Mac Camera is in use (using Apple logs) and then communicate it with the device.
Calling it Door Frame. Had quite fun making it as i learnt 3d design, c++ code using Platform IO and other fun stuff. Even designed a small binary protocol to exchange data over BLE
https://www.pocketpmo.com
PocketPMO is meant for Founders, Project Managers and Project Manager Officers. It allows them to quickly size, cost, plan track and report on multiple projects. Teams can be added, Stakeholders managed, Risks Registered and Budgets tracked.
It is a workflow graph automation site (drag and drop and connect nodes), but is a toy and only allows a local user and local models (both transformers.js and tensor-flow mediapipe), so costs me nothing. Mostly text stuff at the moment, but working on a slate of image stuff this week, may get to audio and video as well, we shall see.
Fascinating. That UI looks like Vercel. What node/graph library are you using? It looks like it would be really useful for some projects I'm working on.
I'm building an app that takes a screenshot every hour from some news websites. It's is a small python script running on my raspberry pi 5 and for now I'm saving the images there. I'm planning to build a front-end app to explorer how each website changes over the course of a day, focusing only on the top of the landing page.
Thanks for sharing the link. I believe dealing with the code adds a lot more complexity to my project. On the other hand, I’d like to visually compare the websites over time, which is easier to do using screenshots.
Basically personalized meal planning and grocery integration. Since the Show HN I posted a couple months back I've been incorporating user feedback to add things like meal prepping, better ingredient reuse across meals, and cooking style preferences.
One of the biggest points of feedback has been adding more grocery stores but I'm really limited by who has APIs to actually integrate with, which is basically just Kroger and Instacart. Walmart has an API but ignored my API access request. Would love to hear if anyone has ideas on how to approach this.
We want to speed up adoption of custom AI, but most people suck at building it (no expertise, money, time, etc.).
We thought, what if you could "Vibe ML" your way to it? Allow any AI engineer or PM to build custom AI directly from their current implementation.
So we built these agents that orchestrate the entire life-cycle of custom AI. We start by hooking into how you use AI, prepare/label your data, detect the best recipes for your task, fine-tune, and deploy it for you. Really tried to simplify the entire process.
We aren't entirely sure about the UX/UI patterns. We aren't going chat first because if most people don't know where to start with ML, how in the world are they going to prompt it!?! Instead, we auto detect the AI tasks you've built and go from there.
a catalog for all deliverables ever made by consultants so that they can search semantically among slides from differnt projects and more effectively reuse their previous slides in new projects
It has an ingestion layer where we break apart a project, it's deck and it's slides into relationships like frameworks/visual archetypes, and then save that in a graph database plus a vector database. The user can then query "find me work we've done on geology research that might be relevant to industrial mining"
I've decided to take a break from working on Pirsch Analytics (pirsch.io) until next year and focus on some side projects instead:
1. Shifu (https://github.com/emvi/shifu) - a code-based CMS with admin UI. It's really easy to set up, written in Go, free and open-source, and I already sold a few websites using it. It can be used as kind of a framework to build more specialized features into a website and takes away the maintenance hell from managing a WordPress installation or a similiar CMS with tons of plugins that break with every update.
2. Zenko (working title, repo is private for now) - a very simple and no-bullshit project management software. It will be free and open-source, but I might offer a hosted option for a few bucks (like $20/year for all users of a team). I mainly build this for ourself to replace Linear, because we don't really make use of it. Don't get me wrong, Linear is awesome, but we basically only need an advanced Todo list. Main goals:
* Pull updates on the dashboard by yourself, instead of receiving notifications all the time via email
* Keep it simple stupid - no unnecessary features, no AI, just the bare minimum
* Cheap (for the hosted version, free if self-hosted) and easy to host (again written in Go)
* No feature-creep
3. Last but not least, I'm working on a "game engine" written in Go and SDL2. I do this for fun, but it is coming along nicely and teached me a few new concepts already (like ECS in Go).
I'm building a utility to help DJs find "play-out" versions of tracks they already like[1]. You can play with it here[2]. Streaming services are optimized for Radio Edits. But to actually mix a track, I usually need the Extended Mix, Club Edit, or a specific Remix. Manually searching for the "DJ version" of every single track in a 50-song playlist is tedious administrative work that kills the joy of digging.
Remixify automates the search while leaving the selection to you. You paste a Spotify playlist URL, and it helps you or provides you a good starting point for digging. It groups the results by the original track so you can quickly preview and save the versions you want to a new playlist.
We don't try to recommend new music or use AI to guess your taste. It just finds the usable versions of the music you already selected.
Blobcache is a content-addressed data store for holding application state, and buiding E2EE applications.
This most recent release includes a git remote so you can push and fetch Git data into and out of Blobcache.
Reading practice and assessments for k-12 students, with reporting and tracking for parents, tutors, and teachers. It uses speech to text and quizzes to assess the students reading ability. It picks up skipped words, substituted words, along with metrics on speed and pauses.
I have been testing it with my 2 daughters and its finally at a spot where I don't have to drag them to test it against their will and they are showing improvement. I am working on the marketing now. I have gotten some interest from private tutors but I have a feeling it will be great for the homeschooling community.
Thanks for any feedback! Please leave first reactions as the marketing page is what I am iterating on right now. Don't hold back!
Working on a low cost email service. Ditched Gmail for my custom domains to avoid lock-in risks, and I believe devs really need stupid-cheap ($10/yr 5GB, unlimited mailboxes/domains/aliases/SMTP/IMAP/webmail) high-quality hosting that nails deliverability with zero spam tolerance. Bootstrapped this instead of pricier options like FastMail. Thoughts?
You may want to check out https://purelymail.com who are pretty close to your target pricing. I've been using them since forever and have no reasons to switch but it is always great to see more players in the niche!
Thanks for your interest. IMAPsync migrations are supported. No CardDAV/CalDAV. For wildcards, do you mean catch all? If so, that is supported as well.
An AI coding tool desktop application written in Rust and Javascript. Cursor, Windsurf and etc uses too much memory on my machine. As an engineer it is important that the tools I use daily are performant and fast and I could use while watching a youtube video or browse hackernews.
While working on the tool I am building some boilerplates to start from, starting with mobile games targeting arcade games like Flappy Bird.
I'm trying to build a native postman alternative using Rust + Iced. I want it to use .http files as its collections and .env files as its environments. So that data is stored in plain text and easily editable by AI and usable by other apps like VSCode rest client.
I've been working (very slowly) on a cross-platform UI library written in C. It uses as much as it can from the OS without outright using the native widgets for everything. Rather the focus is on letting the user of the library customize the look of the controls as they see fit.
It's unfortunate but native UI (as in, using the native controls with their native look) has mostly died off in my opinion, at least for complex cross-platform applications.
You can try to do it in a cross-platform manner but it never works well. Want to implement a tab bar like VSCode's? Win32 tab bars do not support close buttons (need to be custom rendered) and Cocoa tabs it doesn't even make sense for them to have a close button. In Cocoa you're supposed to use either the windowing system to do tabs (similar to Safari tabs) or custom render everything (like iWork).
So I say screw it, make it look as you wish.
The design of the API is somewhat DOM inspired (everything is built up of divs that can be styled). It's pure retained mode for now, I still need to think how I'll make reactivity work.
On macOS it uses a custom NSView to implement "divs". Drawing is done with CoreAnimation layers. Text editing is handled by a nested a NSTextView control with a transparent background. Could also host a web view in a similar manner. Context menus are native.
On Windows it uses a custom C++ class that stores Windows.UI.Composition surfaces for drawing (could also use DirectComposition + Direct2D). Text editing is handled by a windowless RichEdit control (ITextHost/ITextServices). Context menus are native Win32.
On Linux it uses a custom QWidget with a nested QTextEdit control for text editing. I'm thinking of experimenting with Qt Quick for hardware accelerated rendering like the other two.
It’s much shorter than my first book, Effective Haskell, and leans more advanced, especially toward the end. Although the format is puzzle focused I’m trying to avoid simple gotcha questions and instead use each puzzle as a launchpad for discussing how to reason about programs, design tradeoffs, and nuances around maintainability.
It's relevant to software, sorta. I've got rather a lot of GIS/mobility-related data available here. It's just a rails app that renders a bunch of my strava activity data all at once: https://josh.works/mobility-data
The fixes are entirely accomplishable with nothing more high-tech than traffic cones. They can be upgraded to more permanent and pretty physical objects, but the key bit of the traffic bean finds traffic cones fully sufficient. No half-million USD traffic signals, no red/green/yellow light cycles. continuous flow. safety. peace.
Some stuff that's obvious in some domains, like "at high-throughput times, don't allow key bits of infrastructure be completely unusable".
Bringing this to american municipalities is like trying to speak a language with someone that doesn't speak your language, but demands that you treat them as if they do.
it's been a big, long-running project. Most tradition in the USA is really a fig leaf for supremacy, and people can smell that I'm coming for their supremacy a mile away, and they immediately begin deploying emotional defenses.
I've continued to work on an open-source containerized agent framework called Capsule Agents. Lots of progress this month and I have my first one live in my homelab! I'm training for a marathon and its able to send a discord message every morning with the workout on my schedule and the "why" behind it.
Here's the elevator pitch for the framework:
Its built around 3 key ideas I've dealt with inside the agent ecosystem
1. Agents become far more capable when they have access to a CLI and can create or reuse scripts, instead of relying solely on MCP.
2. Multi-agent setups are often overvalued as “expert personas” but they’re incredibly effective for managing context, A2A is the future.
3. Agents are useful for more than just writing code. They should be easy for non-engineers to create and capable of providing value in many domains beyond software development.
I doubt it'll be of interest to folks here - but my Family recently (in the last couple of years) started to breed ragdoll cats in the U.K.
This has been my personal project to understand where I personally find LLMs useful as coding assistants, and where I don't. One easy to spot example is, front-end + copy. Another area I've enjoyed it is talking through how I'd design and build functionality and features ahead of time.
It's been very interesting, and is helpful to folks I care about, even if no-one else ends up using it!
I’m working on DeepCost.ai, an AI-driven cloud cost optimization tool for AWS, GCP, and Azure.
The goal is to help small teams and fast-growing startups understand where cloud spend is leaking and automatically reduce waste (idle resources, over-provisioned workloads, inefficient Kubernetes setups, and AI API usage). Setup is lightweight, and we focus on actionable recommendations rather than massive dashboards.
We’re still early and testing with a few teams who want better cost visibility without running a full FinOps practice.
A Python ORM, inspired by Drizzle and the like. Whenever I come to Python I'm frustrated by the ORM options. They generally lack type-safety on inputs and outputs, or useful type hints.
SQLAlchemy is an institution but I think it's hard to use if it's not your full-time job. I check the docs for every query. I want something simple for the 80-99% of cases, that lets you drop easily into raw SQL for the remaining %.
I'm going to keep hacking at it, would love to from anyone who thinks this is worthwhile (or not). Also:
- The interface for update queries is clunky. Should I add codegen?
- Should I try to implement a SQL diffing engine (for migrations). Or just vendor sqldef/similar...?
Analyzing frontier LLM performance on my favorite daily puzzle game (https://www.nicksypteras.com/blog/cbs-benchmark.html) Next step is to assess how well the LLMs can create their own new, logically satisfiable puzzles in the same style. Then I'll have them battle it out, with one model creating a puzzle and the other attempting to solve it!
Thanks for sharing! I want to have some sort of agentic "helper" to my new puzzles website [1], and I've learned some tips from your post/code, thank you!
Have you given any thought about how to create the puzzles? Do you think it'd possible to create them using LLMs?
I was thinking about what to get my long-distance girlfriend for her birthday which coincidentally was also the anniversary of our first date. So I thought of building her a personal website, installable via tauri so she can view it offline whenever she wants, that has a timeline of all the things we went through: first date, events, trips, moves etc.
Now I want to polish this, make it customizable, add more features like a "Reasons I love you" jar which gives you random notes your partner wrote, and offer it to others as well.
Another thing, it should be a digital living collection of memories and notes for each other and should evolve with the relationship.
Just started with this and building with Elixir and Phoenix.
PS: I realize I might need to update the website. First I wanted it to be more generic and for multiple occasions like anniversaries, birthdays etc but slimming the target down to couples for now to not overwhelm myself. It's the first ever service I'm building.
I started this over the summer when I was moving to a new house and wanted to document the family history behind some thing I own. It's turned out to be more useful than I thought and I've expanded the features as friends found it useful. A developer friend, who I used to work with, joined me and we're both working on it now. It does have a little revenue now but we are far from quitting our day jobs.
I'd really like any feedback from the HN community!
I am working on a text-editor that allows you to discuss specified file folders with AI agents for knowledge work. It is similar to vs code with chat but for non-technical users and not for code.
I feel like I am constantly fighting LLM interfaces to make available and organized the context needed for discussion. There just seems to be way to much copy pasta into and out of the infinite scroll interface. I also find the output tough to quickly edit and discuss with the chatbot.
It is simple enough but I couldn't find anything like it and it has quickly become one of my favorite tools. I am build over buy to a a fault, so if there is something out there like this already I would not be surprised.
This was a "scratching my own itch" project that I cooked up because I was tired of Claude et al cluttering up all of my stuff with random markdown files. Just a simple Obsidian plugin to serve an API that the CLI tool can use to interact with the Obsidian vault. I use a Claude Skill to get the model to create all of those random markdown files in my Obsidian vault, and read from them when it needs context for something. It's working really well for me so far!
I've spent the last week starting to hand port SeL4 to rust. Mostly because I want to learn how kernels & capabilities work. This seems like a fun way to get my hands dirty with operating systems without needing to invent everything from scratch.
To be clear, there's no benefit to using rust over C for SeL4. SeL4 is formally verified - which provides a level of assurance far beyond what the rust compiler can check at compile time. I'm really just doing it for fun and learning. I've been wanting to really understand sel4 for awhile, and there's something wonderful about learning it from the ground level.
So far, I've got a stub booting. The CPU successfully boots into 64 bit mode and starts running my rust code. I'm starting with x86_64 because thats whats on my desk. At the moment I'm porting the code which locates the root process via multiboot, so I can set everything up in memory correctly.
I'm looking to leverage the upcoming WebNN browser spec with my spreadsheet app. I think integration with vision, audio and language models opens a whole new world of possibilities as traditional spreadsheet apps lean more towards mainly numerical data.
Hyperclay: a way to package up HTML files as portable, editable apps that contain their own editable UI. I'm using these simple apps to plan, edit emails, write blog posts, and a lot more. I edit them on my mac and they sync to the web live.
It feels like being able to design my own document format on the fly and display it however I want. It's making it painfully obvious how many editable primitives the web is missing, however.
It aggregates data from across the web into a single feed, pulling in news, weather, newsletters, social posts, Reddit, YouTube, and more.
I also finally launched my first iOS app that goes a step further. During onboarding, you set your preferences once. From there, AI automatically prepares your daily digest for you. Each morning, you get a notification when it’s ready, with everything relevant for the day ahead: meetings, weather, health data, commute insights, and the news you actually care about.
I believe it was sold off and is no longer maintained -- their changelog shows no updates since 2023. We constantly update the platform, and have more sources available plus a mobile app.
There's a gap in most security tooling: it's not IN the terminal with you. It doesn't have enough context: your environment, your repo state, your current directory, etc. to catch the small hygiene mistakes that accumulate over the many tiny decisions you make every day to ship code and learn new tools. Those "cut corners" add up, and can lead to costly blunders.
Dashlights attempts to bring awareness and visibility to your immediate shell context.
It's feed aggregator backed by a web crawler that tries to find interesting RSS feeds. Posts are sorted by inverse frequency with the hope that time between posts will serve as a good proxy for quality.
I've been having fun with it! The results are a little strange, sometimes, but I've found some interesting sites that I never would have found otherwise.
My next step is documenting how all of the subsystems work (such as virtual memory, allocators, drivers, etc.), then lay the project to rest. I don't have any grand ambitions for the kernel. The project was just a labor of love, and a way to learn some interesting things! Hopefully some of the documentation can serve as learning material for other people interested in osdev.
Currently I am working on an insurgency game mode; where one team has to defend some caches and use guerilla tactics, whilst the other team has a smaller size but the advantage of firepower and vehicles.
I was into playing the mods for the original and played some of 2142 on PC.
Has the official multiplayer gameplay held up? I did try a release around the time of RDR2 on Xbox and it had seemed like pay to play may have messed with it at some point.
Curious if the mod support seems like a jailbreak from the official multiplayer.
It's mainly a distraction from enterprise programming, but it does have some parts that might be interesting to Lua programmers, like automated test suits, functional programming point free style and deploying to a raspberrypi via justfile.
I'm working on building out a microservice ecosystem on OCI. I'm not formally educated so I just sort of stack things up and tear them down. I hardened my server and I am running dockerized services. I'm also running a web server that hosts the very start of my long-term personal site. It's been pretty challenging, illuminating, and down right fun. I've been putting down the controller for a terminal!
Seriously, I'm very proud of myself for the little I've accomplished so far. I don't have friends in tech so I don't get to talk about it or bounce ideas off people.
Sounds cool, I tried kubernetes out on a few rpi4 devices as a small build farm, but that didn't quite work out, too resource hungry for the small PIs.
Getting sth like that going with less RAM, infrastructure would be cool!
I started a project involving several aviation tools while doing ground school for my private pilot license. It started as a way of learning the maths, and a replacement for the E6-B computer.
It is opensource, all the computations are done on the client side,
Working on a Graph-RAG integration with Claude Code. My work has many interconnections (components used at multiple clients for example) so learning the graph db way of thinking has been very interesting. I have created my own memory mechanism and use the database to feed a personality into the experience. Tons of fun.
A matching decompilation of snowboard kids 2 for the n64. Why this game? Well it's awesome but also I wanted to work on a decomp project from scratch. I've written several blog posts about my experience for those interested. I hope to do more in the future, probably with less of an AI focus.
Awesome! Good articles. I wonder why you didn't use first a more traditional decompiler such as Ghidra or HexRays to generate "almost-C" and then use Agents to give them meaningful name and semantics?
https://finbodhi.com — It helps you track, understand, and plan your personal finances — with a double-entry accounting. You own your financial data. It’s local-first, syncs across devices, and everything’s encrypted in transit. Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more.
Soon, we will have benchmarking capability. You would be able to compare your networth growth with inflation, compare your investment returns with benchmark etc. We would support both nav and value based benchmark. The topic is interesting in itself, and somehow, not emphasized/available in most tools.
Asset price fetching and benchmarking works best for Indian markets. We would like to build better support for international assets and benchmarks, but haven't figured how to get the data.
NOTE: you can try demo without signup, but it doesn't work in Firefox Incognito mode.
I was using another paid tool my accountant suggested. Then I decided to build my own tool, but free and open-source. It gets the job done at least for me plus I have some ideas how can I improve it further. For example I built a simple automation where an invoice is generated every month, emailed to me for review, and then I forward it to the client.
I'm working on Tech Talks Weekly which is a free weekly email with all the recently published Software Engineering podcasts and conference talks in the past 7 days.
Every week I pull all the new talk recordings from hundreds of conferences (Devoxx, KubeCon, PyCon, QCon, LeadDev, JSNation, and many more) and even more podcasts podcasts. I feature the ones I think are must-watch with short summaries written by me, then include a list of everything else uploaded that week.
It started as a personal project to fix my own messy YT subscriptions and RSS feeds and now 7,500+ people read it.
I also publish extra editions from time to time like “The Most Watched Talks of 2024” which made it to the HN front page.
If you watch software engineering conference talks or listen to podcasts, you might find it useful.
Cool. What do you mean by 'manually' and 'some' delay?
If you have a list of posts you pull data from, it would be nice to have a simple clickable list of them all on a separate page. Also, (month year) could go next to neat 'View on HN' on each item.
So, not bad in terms of 'manual' update, but still needs some of your time, right? Anyway, interesting to be able to see these posts in this way. Nice work with tagging - will check/explore how these work.
I’m still working on MLSync.io, an ETL platform designed to remove the technical friction of synchronizing MLS data using RESO protocol and provide simple access to the MLS data via SQL and REST API.
And as everyone now, I'm experimenting with LLMs to bring some new AI-related features to the service.
On another project, we've now beta testing (in ordination) Asus GX10 processing power running on-device LLMs for _local_ processing of patient medical data for 'differential diagnoses, implant plans and risk profiles in real time while the patient is in still in the chair'.
Video intelligence platform for coaching programs and training companies. The problem: these businesses sit on 200-500+ hours of video content that becomes a "content graveyard" - students can't find what they need, coaches burn out answering the same questions, churn stays high.
We do deep transcript + metadata extraction, then layer RAG search and an AI assistant that can answer questions with timestamped citations back to the exact video moment. Think "ChatGPT for your video library" but with accurate sources instead of hallucinations.
Tech: Phoenix/Elixir backend, Next.js portals, two-tier RAG architecture.
Currently serving a few coaching programs in high-touch sales mode. Would love feedback from anyone who's built RAG systems over media content - curious how others handle the signal extraction problem (transcripts are noisy, you need to identify what's actually being taught vs filler).
My "test prompt" for AIs used to be to create an extension to manage tabs. After a year and with MV3 the extension I used to kill duplicated tabs died.
Wanted to save up a few tokens when passing data to LLMs and did not like anything on the market, so I made minemizer.
Minemizer is a data formatter that produces csv-like output, but supports nested and sparse data, is human readable and super simple.
It produces even less tokens than csv for flat data, due to most tokenizers better tokenizing full words that contain a space before the word, and leads to less fragmentation.
There are many cool things I discovered while running tons of testing and benchmarking, but it's getting late here.
EDIT: Ignore latency timings and token counts in "LLM Accuracy Summary" in benchmarks as different size datasets were used to generate accuacy numbers while I was running tons of experiments. For accurate compression numbers see compression benchmarks results. Or each benchmark one by one.
I will eventually fix all the benchmark numbers to be representative.
Back in 2019 I created a Google Spreadsheet titled "family debts" that allows my family (4 siblings and my parents) to record when we owe each other money, and periodically settle up. I later learned that I recreated Splitwise, but having something like this with trusted folks has been hugely useful. We have over thousand entries, and use it constantly for splitting gifts, buying something at the store for someone, etc.
Om Friday after Thanksgiving I spent half a day building a telegram bot that accepts an address and a list of Amazon links, and in turn orders the item (at a discount since it uses my Amazon credit card), and adds it to the above "family debts" spreadsheet.
I really like the idea of programmable, trusted lending like this, and feel like it could be extended to other groups that you implicitly trust.
Writing articles about how to test frontend apps (mostly react based apps) at https://howtotestfrontend.com/
Adding some final bits to some new vitest browser mode content this week hopefully.
I've spent a considerable amount of my free time over the last few years working on an open-source game engine for making Zelda-like games (link in profile). It's been around for a few decades, and I played it when I was a kid - and now I'm contributing heavily to it. To give a since of scale, there's ~1000 custom fangames made in this: so pretty niche, but if your thing is Zelda it's got some real gems.
Most of my time has been spent practically rewriting the engine from just single-screen play areas (like Zelda 1) to be free-scrolling (like Zelda 3). I've also put lots of work into supporting all platforms (was just Windows; now it's also Mac/Linux/Web). And I've delved into tons of interesting programming projects while working on this: a deterministic record + replay testing system; a garbage collector for our custom scripting language; JIT compilers for x64 + WASM; a VS Code language server; the list goes on...
Anyhow, this month I'm trying to polish it up as much as I can so we can officially release the next major version.
Then I decided to hack my own ZigBee power meter (to keep track of my meter’s LED pulses) and fought with CMake for eight hours straight, because embedded.
A typed execution graph for Go. You write functions with typed inputs and outputs—Docket infers the dependency graph, runs independent steps in parallel, and caches what you tell it to. It integrates with River and a number of data stores.
I spent a year attempting to adopt Temporal at scale, and 6 months trying to wrangle some multistep data enrichment and ML pipelines. This is what I wish I'd had with what I learned
Building https://programmer.network/ with a hope to eventually gather like minded nerds that value their privacy, time, and who don't want to be victims of engagement algorithms. Building it live on Twitch past couple of years, with very limited amount of time, but it's fun, engaging and still enjoyable.
Helping friends (and friends of friends of friends of friends) find their next startup gig without the application process. Aspiring to be Wealthfront for your career… a passive optimization that pings you every now and then with an interesting interview you could take.
Thinking a lot about how to recognize great matches. I think basically everyone can be talented force multipliers in the right situation / company / mission / team. Everyone here wants to do their life’s work, but it’s hard to find it.
Tactically working to scale reliable human-in-the-loop AI recruiter agents with very few humans.
The first is a customizable digital math workbook. Currently the demo covers fourth grade math. There is a practice mode where you can select the skills you to want practice. There is also a customizable dashboard where you can setup your own widgets to practice math skills in different ways. I am working on some pre-made dashboards to help users get started. The next plan is to cover fifth grade math skills. My plan is to cover first grade math up to Calculus and High School Physics. I envision it as a companion tool for Khan Academy/Math Class/Math Books. Check out the demo. No signup required. Progress is only stored locally.
The second thing I am working on is an application to practice Cangjie. It's a Chinese input method that has been around for a long time. It is based on a visual decomposition of characters. Each character is represented by one to five codes and the majority are unique. My application teaches Cangjie like keyboarding (QWERTY) is taught to young students. You learn the location of the keys, then some basic words, then start typing sentences. I also have a free demo for it as well.
I'm in crunch mode doing the internationalization and localization of my spreadsheet engine. This is a rabbit hole and a nightmare in Excel, so a big opportunity for us to get this right.
Glad to see you're doing this! I was wondering if the currency button could be changed. Defaulting to Euro is fine, but being able to switch that shortcut would be handy.
A 2-4 player casual card game that's similar to Exploding Kittens. It'll be free-to-play on mobile and I've been focusing more on marketing these days (mostly running ads, creating short form content, and reaching out to influencers).
I'm using Unity for the front-end, and Node.js (just because I'm already familiar with it in terms of dev + liveops) for the gameservers.
My blog. I created it a couple years ago but didn't really know what to do with it. Have started to use it as a way to learn and have enjoyed writing more than I thought I would. Nothing crazy with UI and I am not talking about anything groundbreaking, but it's been fun!
We’re working on an AI-first interview platform for developers: Valuate.dev
The usual approach to coding tasks doesn’t work anymore - companies are looking for AI engineers, yet it’s still unclear how to assess AI proficiency.
Our goal is to design challenges that combine prompting + coding, allowing us to score both how well a candidate prompts and how good the resulting code is. The aim is to bring measurement to AI prompting skills - how well-aligned prompts are and how candidates handle LLM-generated code.
At the same time, we want to keep a strong human balance in the process: hiring is a two-way street, and screening shouldn’t be fully offloaded to AI. We’re human-first.
I'm making a cat themed puzzle game for my wife using NiceGUI, MindAR and some cat shaped sticky notes. Each note has a name and a secret code. I've hidden 20 of these around the house. I set up a single page app in NiceGUI to display a grid of the lost cats. When you click one it'll display their name, a clue to its hiding spot and an optional hint. 5 of the puzzles use MindAR that will display AR image cards over different art pieces and book covers in our house. I have the NiceGUI page and MindAR set up on one of my Proxmox LXCs that I use for various Flask servers.
Taking a break from software to remodel a house by myself. The plan was just to redo the kitchen and a bathroom and be done by August, so naturally it's now December here in Minnesota and the house is missing most of its wiring, pipes, insulation, and walls. :) I'm having a great time though and just started producing videos about it: https://youtube.com/shorts/6QDOXxh99PY?si=NOjvNVEVHwQt180A
LLMatcher - blind testing arena to find which AI model actually works best for you.
You enter prompts, compare two anonymous responses, pick the better one. After voting, it reveals which models you preferred. Built it because model benchmarks don't match real-world preference, and blind pairwise comparison cuts through the hype.
Primary goal with the project was to create a Bluesky client that I wanted to to use. While the standard Bluesky app is fine, I wanted something more reminiscent of Tweetie, Tweetbot, Twitteriffic, etc. Something that feels at home on the iPhone. With the transition to Liquid Glass, felt like a good time to practice and get to experience the new UI with a new project.
Still in what I call "alpha", but pretty feature rich. Support push notifications, lots of discovery/feed following features, search tools, moderation setting management, post translation, and much more.
If you use Bluesky and are an iOS user, there's still space on my TestFlight and would appreciate any feedback or comments!
I have been working on a customizable AI voice dictation tool using Pipecat's framework to swap between many providers and models, including cloud or local.
Started off as an open source alternative to Wispr Flow for myself as I wanted to have more control over the formatting rules as well as model choice but after sharing with friends and presenting it at my local Claude Code meetup, I was encouraged to share it more widely.
The desktop app uses tauri so it is cross-platform compatible and I have tested it working on macOS and windows.
It allows users to "chat" with their Logseq graph. Think of it like a "Cursor for Logseq". I hope people find it useful. I have on numerous occasion wished that I could have easily asked about a specific block on my graph, and would provide an intelligent response, also somewhat influenced by the contents of the entire graph. It's still a work in progress.
Working on a house renovation project in SketchUp, I wanted the same workflow I use with Claude Code: describe what I need in natural language, let AI write and execute the code, iterate quickly.
So I built a bridge. Python MCP driver talks to a Ruby extension inside SketchUp via JSON-RPC. Claude Code can now write Ruby scripts, execute them directly in SketchUp, take screenshots to verify results, and introspect the model - all without leaving the conversation.
Still very early (macOS only, requires SketchUp 2026), but it's already useful for repetitive tasks and parametric designs. "Create a spiral staircase with 15 steps at 18cm rise" is more fun than drawing it manually.
I'm working on ffl (https://github.com/nuwainfo/ffl), an Actually Portable Executable (APE) that turns any file or folder into a secure P2P HTTPS link via WebRTC.
Like llamafile, it's built on Cosmopolitan Libc. Getting the full Python stack + WebRTC to run as a single APE binary was incredibly tricky to pull off, but the result is super convenient. I mainly built it to solve the pain of moving large files (logs, DB dumps) in and out of containers—now it's just one command.
The repo has a demo showing a round-trip transfer between Windows (x64) and Android (arm64) using the same binary. I hope you give it a try!
Working on CiteLLM, an API that extracts structured data from PDFs and returns citations for each field (page + coordinates + source snippet + confidence).
Instead of blindly trusting the LLM, you can verify every value by linking it back to its exact location in the original PDF.
I'm working on a hardware/software utility to play Switch/Switch 2 games remotely with my brothers. I found a way to emulate a Switch Pro Controller using a Raspberry Pi Pico based on several different sources (look in the README for more info). I used that to write a firmware for the Pico (with the help of GPT Codex 5.1).
Then I wrote a Python program that connects whatever controller my brothers want to use (as long as it's supported by SDL2.0) and forwards that data from their computer, through Parsec, through a USB-UART adapter, to the Pico, then to the Switch. I then have a low latency capture card (Magewell Pro Dual HDMI I got off of ebay for $100) forwarding the video and audio from the Switch to my PC which I share to my brothers via Parsec. The audio was a bit tricky to get right, and ended up having to use a Virtual audio cable and Voicemeeter potato (a software audio mixer) so that both myself and my brothers could hear the audio.
It works surprisingly well and the latency is pretty low. I even got rumble working! (but not motion controls. If anyone wants to attempt it, I will accept PRs). I haven't done any formal benchmarking for performance, but my brothers and I were able to play Smash Ultimate without too much bother about latency.
You could also use the accessory Python library I made to automate switch controller presses (look in the examples directory). Might be useful for TAS speedruns?
The project is here for anyone interested. It's a bit rough and needs some cleanup and maybe a video tutorial on remote setup. But here is the WIP:
I’ve been working on a TLS proxy/TLS terminator that can handle 3000 TLS handshakes per second (basically an stunnel replacement, but stunnel crashes at under 100 handshakes per second) as a pet project, but I’ve realized that with some polishing this can be really useful.
This is still in development (todo are privilege dropping, in place config reloads, log burst suppression, multiple listen sockets (which paired with the Linux kernel gives free load balancing capabilities), and detailed TLS configurability), but it already matches both nginx and HAProxy’s speed (entirely bottlenecked by OpenSSL crypto by this point) at a tiny fraction of the attack surface and memory footprint (10-15kb per worker process last time I checked).
If anyone wants to take a look, please roast my code :)
Egoless Engineering, a book about how to be an enabling staff engineer in the Nordic's largest mediahouse. I saved up vacation and took the whole of December off, mostly to relax. But I'm also working on more chapters for my book.
It's essentially a book progress tracker. There are many apps that allow you to add the books which you are reading currently, but not at what pace.
It's simple, no complicated stuff, no AI shenanigans.
Created as I was overwhelmed by the number of books I want to read and thought it would be helpful to plan ahead.
You add a book name, number of pages and how many pages you want to read in a day.
It calculates and gives you the number of days and on which date you will finish.
It's also flexible to increase the number of pages so that it can recalculate.
It's a PWA for now. Still working on notifications and stuff.
its a web app where you make boxes, add images or text of what's in the box. then get a qr code that you can tape to the box and scan to see the text or images in the web app.
hoping to make it a lot easier to look for things in the storage unit. instead of removing all the totes and looking in them. Just scan and see if the description fits what I'm looking for
Most recently (yesterday), vibe coding a better interface for Roblox screen time: https://github.com/astrostl/blockblox . Claude Code crushes, and I'm preferring Go for everything I can to take advantage of typing, quality ecosystem, and distribution. Still need to implement the QE side on this as I have on other things.
Currently in the works are a digital sand timer which can be used to track pomodoros (or any sequence of time intervals), and a Jovian orrery which displays the positions of Jupiter’s moons on a strip of addressable LEDs.
Building Contextify - a MacOS application that consumes Claude Code and Codex transcripts, stores them in a local sql db.
The main window uses Apple’s local LLM to summarize your conversation in realtime, with some swoopty UI like QUEUED state on Claude Code.
I’ve just added macOS Sequoia support and a really cool CLI with Claude Code skill allowing seamless integration of information from your conversational history into aI’s responses to questions about your development history.
The CLI interface contract was designed to mutual agreement between Claude code and codex with the goal of satisfying their preferences for RAG.
This new query feature and pre-Tahoe support should be out this week, but you can download the app now on the App Store or as a DMG.
I’m very excited about this App and I would love to get any feedback from people here on HN!
That’s an interesting direction. I haven’t thought of this in multiplayer sense.
Would you see this as something that is sort of turn-key, where a central database is hosted and secured to your group?
Or would you require something more DIY like a local network storage device?
And similarly would you be open to having the summaries generated by a frontier model? Or would you again need it to be something that you hosted locally?
A central service. Hosted, secure, frontier model is fine. I’m thinking this through it’s probably something GitHub or an addon should provide.
But maybe it starts local with an app like yours anyway. I do a lot of solo hacking I don’t want to share with the team too. Then there is some sort of way to push up subsets of data.
I can see github providing this, but it would still be at the git-operation level.
What I've found using this contextify-query cli in talking to my project(s) CLI AI history is substantial detail and context that represents the journey of a feature (or lack thereof).
In high velocity agentic coding, git practices seem to almost be cast aside by many. The reason I say that is Claude Code's esc-esc has a file reversion behavior that doesn't presume "responsible" use of git at all!
What I find interesting is that neither Anthropic nor OpenAI have seized on this, it is somewhat meta to the mainline interpreting requests correctly. That said, insights into what you've done and why can save a ton of unnecessary implementation cycles (and wasted tokens ta-boot).
Any thoughts on the above?
If you're open to giving the app a try, and enable updates on the DMG, the query service + CC skill should drop here in a few days. It's pretty dope.
Anyhow, this is really cool feedback and I appreciate the exchange you provided here. Thank you. If you have any further thoughts you want to share I'll keep an eye on this thread or can be reached at rob@contextify.sh
I got a couple new toys for birthday/xmas: the GPD MicroPC 2 UMPC and the M5Stack Cardputer.
The MicroPC is great because it makes it super easy to code and hack on something in places where it would be too awkward or annoying to whip out my laptop, and the Cardputer is just a fun little toy because it's so open ended and hackable. I've been writing an app for Cardputer to control my thermostat remotely, and I've had a lot of fun grossly overengineering the needless amount of concurrency I have added through FreeRTOS.
Something oddly satisfying about using a micro PC to program an "even more micro" PC. What a cool time to be alive; I would have killed for this kind of stuff as a teenager!
Stuff like the MicroPC excites me. Even though, logically, you hardly need need a micro pc but the hacky excitement of using it is worth it. I have also been looking at purchasing the MNT research pocket laptop.
On Thursday I learned about ulid[0] which I think really neatly solves the problem of text representation for UUID v7. However, I also like the idea of prefixed ids, although I haven't used them in anger.
Yesterday I built most of a Postgres extension, using the excellent pgrx[1] project, that build on ulid to add prefixes. With it you get something like this
I'm working on finishing my JS KV compatibility library polystore [0], the goal is to make a widely compatible library to connect to many stores so that you can have a wide range of stores easily accesible.
For example, you make an API client library, now you can add polystore and accept multiple cache stores without writing all the compat layer yourself. This is a problem I've had multiple times in the past.
Or you make a project with cache, having it in files for local dev (highly debuggable) and then with Redis in prod is a simple ENV var change:
let store;
if (process.env.REDIS_URL) {
store = kv(RedisClient(process.env.REDIS_URL).connect());
} else {
store = kv(`file://${process.cwd()}/cache/`);
}
I've made many other libraries and projects during the years and having a single library handle all of this would be great.
A small startup generally needs to explore and edit the production data. They would either build an admin dashboard, which is expensive, or use a database tool, which is bad for security. Not to mention a tool like pgadmin and dbeaver is clunky because they focus on database administration.
Backdoor is a self-hostable database querying and editing tool for teams. It reduces the need of an expensive admin dashboard. You can configure access control and validation policy for each user. The activities are tracked. It saves money and time, and it's more secure.
You can have your non-technical CEO, customer support, and sales to edit the production data in a safe and secure manner.
It currently supports Postgres and ClickHouse.
I'm looking for early users to iterate with. If this resonates with you, please reach out to me through the github repo: https://github.com/tanin47/backdoor
I'm building a temperature controlled dough proofing enclosure based on ESP32, an IKEA Samla storage box and an inexpensive silicone rubber heater. It's delightfully impractical-- purely a first hardware/MCU learning project and a holiday gift for a relative who I think will appreciate it.
I'm impressed by how far I can get "vibe making". Most of my professional experience is in high-level software, but AI gets me unstuck quickly when I don't know something specific to ESP-IDF or the hardware. As of today I've got a circuit tested, firmware nearly complete, and a custom PCB en route from JLCPCB.
One limitation I’ve noticed: ChatGPT struggles with the details of part selection (e.g. choosing specific temp/humidity sensors or connectors). Adding datasheets to the context helps a lot, which makes me wonder why this isn’t something the model can do or at least ask for.
We are working on DB Pro, a modern desktop data workbench for developers and data engineers.
The focus is on going beyond a query editor and building a complete environment for working with data. Visual exploration, inline editing, dashboards, and Jupyter notebook style workbooks for queries, notes, and experiments all in one place.
We launched v1 a few weeks ago and the reaction has been genuinely jaw dropping. Downloads, feedback, feature requests, and some great long form discussions around real world data workflows.
We are documenting the entire journey through a public devlog series. The latest video covers the v1 launch.
Published my first AUR package this week. It's called bleep, a simple interval timer that beeps.
The idea came from cooking bolognese. I needed something to remind me when to stir. So I wrote a small Go tool that just beeps at whatever interval(s) you set.
Then I kept adding stuff. Verbose mode with a live countdown, pause/resume with signals, and a JSON output mode that works with Waybar. That last one is actually my favorite part. I get a little timer in my status bar that changes color when it's counting, paused, or beeping. Click to pause. Works great for pomodoro or just keeping track of things while working.
I switched from Mac to Arch and wanted to try the whole AUR thing. Used GoReleaser to automate the build and publish. Took some fiddling but it works now.
We've been building https://nimstrata.com/ for almost three years now, we put Google's Vertex AI product discovery algorithms on Shopify and Salesforce ecommerce storefronts.
At a high level, Google does not have a product culture, so there is a lot of white space for companies like ours to make adopting Google Cloud APIs much easier for less technical users.
It's also wild how much Agentic AI is creeping into all of our conversations - this space is constantly evolving as we're building.
An annoying little laptop charging reminder utility that does the job.
---
There are times when I'm deeply immersed in focused work, a meeting, or engaging video content and end up missing the usual low-battery notifications on my MacBook.
When the laptop suddenly shuts down, it's followed by the familiar and frustrating walk to find a charger or power outlet. It can be annoying and occasionally embarrassing, especially when rejoining a session a few minutes later with, "Sorry, my battery died."
Over the past few weekends, I built Plug-That-In, an app that introduces "floating/moving notifications". These alerts follow the cursor, providing a stronger, harder-to-miss nudge regardless of what’s happening on screen.
The app also includes a few critical features:
- Reminder Mode: When the battery reaches critical levels, the app emits a configurable alert similar to a car's seatbelt warning, continuing until the battery is addressed.
- Do Not Disturb Settings: Customize alerts and sounds based on context, such as when system audio is playing, a video is active, or the camera is in use.
It grew out of a personal need, and I'm glad to see it used by over 50 people in the past month.
Glad you found it relevant, and thanks for sharing the feedback.
Not going to deny that it was a bummer to read your second line, lost all the Endorphins earned from reading the first one. Nevertheless, I want to fix this if it's a legit issue.
Do you mind sharing more details on the battery consumption from the app?
I'm using IOKit power source notifications and hearing this feedback for the first time. (personally using this on my work [old M2] and personal [new M4] MacBooks for the last ~2 months).
I built https://nofone.io . I ingest health insurance policies and provide insights to insurers on how to improve them and doctors to know what insurers expect to see in documentation and evidence. My hope is to improve the denial situation and standardize medical necessity criteria down the line.
https://fooqux.com/ - an experimental article aggregator about software development. For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website.
The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experimental features like annotations, questions, etc. I hope this service might be useful to others as well.
Building https://localhero.ai, automated on-brand i18n translations that run in your CI pipeline.
Right now I'm working on better .po/gettext support, based on feedback from an early customer. With gettext you usually keeps source strings in the actual source code. So I'm building a workflow where non-technical people (PMs, designers) can edit translations in the web UI and then easily generate a PR with both code changes and translation file updates. Trying to make translations work smooth for both automated CI pipelines and PMs/designers who don't live in Git, when translations are checked into the repo. Also going through my network, talking to devs and localization folks to understand what could be improved in their orgs for translations.
Nice! We use an internal workflow with translations by llms at Minut. This looks smoother, esp as everything is driven through the PR. Swapped out lokalize for cost reasons.
Working on an MPC stack to make it easier for devs to integrate privacy into their stacks.
As normal folks increasingly value the privacy of their data, developers will need to think about how they can build apps while guarding their users' data. We provide tooling for them to do this.
Still WIP but we are getting our first audit in the coming days!
At work I'm working on autonomous agents for web application testing, and in my spare time I've been taking some part-time evening courses at the local university for the first time.
Last term I did a course on nuclear weapons and disarmament (and learned to write my first ever academic report!)[0], and this term I'm just about to give a final presentation for an introductory life sciences course (actually just posted a runthrough recording [1]). Next term I'm hoping to get into a course about cosmology!
I am currently on the job hunt and made a job application tracker. It's a CSR React app that uses LiveStore (https://livestore.dev/), a reactive state library built on top of WASM, SQLite, and OPFS. The app enables you to track applications, leave notes and updates, and gain insights into your data, while storing your data completely within the browser.
I’m building an online memorial product in China, currently used via a WeChat mini-app and web pages by local governments and cemeteries for digital remembrance.
I’m now exploring a global version (web + app) for families worldwide — especially those separated by distance.
The current product is in Chinese, but the idea is universal. I’d love feedback, and I’m open to marketing or distribution collaborations.
We’re also considering adding AI capabilities — e.g. AI digital humans, voice cloning, or other respectful AI applications for remembrance in this sensitive domain.
Still working on the Mint programming language (https://mint-lang.com/) with a 1.0 release in January :). I'm happy with the current feature set, so I'm just polishing and optimizing where I can and giving the documentation a throughout look.
IMHO, Marko and Mint target different things. Mint was specifically made to create Single Page Applications, whereas Marko seems like more for general all things web.
Building https://canonicalschema.com/, I started with a simple CSV viewer because none of the existing online tools supported large files or provided flexible column statistics and filtering to easily understand the data. My plan is to grow it into a full application where users can more easily manipulate and analyze CSV or spreadsheet data.
I recently open-sourced my first ever tool! and I'm super excited about it guys
It's an HTTP request replay and comparison tool in Go. You can replay real traffic, compare multiple environments, detect broken endpoints, generate HTML/JSON reports, and analyze latency
It’s currently at v0.4, so I’d love any feedback, suggestions, or ideas for improvements. (Be gentle, I haven’t used Go professionally, however it’s my main language for personal projects )
I have built a AI powered home improvement platform with live consultation with pros.
I am not sure if I will go live with it.
It allows those professionals experts across the USA provide help to Do It yourself consumers for a fee. Consumers can be anywhere.
So I married sort of like Uber (rent skills) + upwork (rent + fees) + FaceTime + e-commerce. realtime audio transcription that identifies parts you need and builds a list for pros and you to review which you then go shop.
:

• Pros during slow seasons
This unlocks underutilized labor.
⸻
4. Lead Conversion (Optional Upside)
• If an issue requires in-person work, pros can:
• Convert the session into a local job lead
• Or refer the job and earn a referral fee
Cross-platform game framework for/in the Odin programming language. It's also the foundation for my first Steam release. The plan is to get something out on Steam, roll with the punches (bugs,) then open it up for general-use. I say "framework" instead of "engine" because the scope of the project is to make the decisions the beginners get stuck on and free them to make a game. That's a smaller goal than what you see with Unity, Godot and Unreal, but I am already at the point that I'd rather use my thing than Godot.
Publishing everything local councils do in the UK at https://opencouncil.network - trying to help people feel like they know who and what they’re voting for next May.
It’s been incredibly rewarding to see people’s changing opinions of their local government
It's a travel tool for business travelers that figures out your suggested departure times for your entire itinerary based on predicted traffic patterns. Think Flighty but for all the non-flight parts of your trip.
You first build a travel itinerary with your legs - flights, activities, hotels (and hotel returns) and it tells you things like "leave your hotel at 7:40am" before your 8:30 meeting - in a single itinerary, no need to do the google maps acrobatics for every two items in your itinerary.
While it's aimed at frequent business travellers I personally use it for all family leisure travel and daily itineraries around town as well - "do I have time for lunch at home after my son's class or should we bring packed lunch".
I built it as during my time working in developer relations I traveled a lot, and always built unnecessary buffers and kept nervously glancing at my watch or phone to see if my planned time to leave still holds.
Tech-wise, currently it's Remix web app with a NodeJS/Fastify backend and Supabase for storage, and relying on google maps for route duration calculations. I want to expand it to native mobile clients in the future as well.
I am using it as playground on product thinking, ruthless prioritisation based on user benefit, figuring out unit pricing and economics, sensible architectural design, and exploring how including AI-enhanced features here and there can help make the product better, not just include them for their own sake.
I've been hard at work building a weightlifting workout tracking & analytics app. Its main selling points are being iOS native, being a one-time purchase, and being completely private (does not depend on a backend, but still saves data to the cloud).
If it sounds interesting, you can sign up for a waitlist here, it even includes some screenshots: https://plates.framer.website/ (excuse the website being on a framer domain, i promise the app is far more professional)
Site where you can read and generate graded Chinese stories, in order to learn Chinese. What's a graded story? It's one written with the vocab of a {X} year old. Words are often repeated, so that you can learn from the left-and-right context. I normally pay for book versions of these, so I thought, why not make one that's online and free?
Use Case:
Assumption: You have access to your friends visitor parking login in Amsterdam.
You are going to a restaurant/or visiting a place near their parking zone(geo fenced polygon). You want to pinpoint a point in map and drive to that point. Being 100% sure that you can park at that point. Automatically pick a meter near there spot and park almost instantaneously. Then this app is for you :D
Added a fifth project this month. Most likely very unwise...
1. probe.bike - tell stories with your bike rides. It allows you to aggregate your cycling trip into one datapoint. Will likely break this out to skiing over the break and rebrand slightly. Adding yearly cards as we speak!
2. flopper.io - I'm seeing traffic rise and rise for this and it's been a great way to translate my every-increasing understanding of AI Infrastructure architecture to a new project. It acts as a benchmark website for GPUs and systems (e.g. Nvidia NVL72.
3. llmstxt.studio - still feel like llms.txt as an idea make sense - so hedged that and but let's see. Got my first customer this month. B2B and need more features/marketing.
4. rides.bike - the oldest - a catalogue or well researched cycling destinations and information about destinations. Will be adding more very soon!
I'm working on a charitable donation tracker for taxpayers. My wife and I used Intuit's ItsDeductible for years until it shut down in October. With a little encouragement, I built Charity Record.
The stack is Django 5.2 (I know, I know, I'm looking at 6 now), Postgres, and HTMX + Alpine.js for interactivity. I'm using Polar for subscriptions. It's running on the $12/mo DigitalOcean droplet.
Trickiest parts so far: TXF export (we can trace TXF back to the 1990s...) and PDF generation. At one point when working on PDFs, WeasyPrint was deadlocking a single-worker setup because it fetched the logo via HTTP. (Base64-embedding the logo got me past that, ha.)
Happy to answer questions about the app or running Django lean - I've got a few longer running Django projects.
Have been working on an app to capture thoughts and to make sense of them with a timeline view. Have posted the first version here and got a lot of suggestions so that we continue working and now release an open testing version to play store. If anyone interested in trying please visit
I’m working on Yomu, an iOS app for reading Japanese text with adjustable furigana.
I’m learning Japanese myself (recently took JLPT N4), and I noticed that full furigana makes me rely on readings instead of actually reading kanji. Yomu lets you hide furigana for kanji up to your level and keep it for harder ones.
It’s offline-first, supports importing text from anywhere, camera OCR, and a fast dictionary.
https://wordcollector.netlify.app An offline dictionary in your browser. Dictionary is pulled from the open source wordnet dataset and cached in browser as a sqlite database. Installable as a PWA as well. Working on adding a study mode to review words that you’ve looked up in the past to help commit them to memory and adding synonyms and antonyms. Plans to add multiple languages in the future so you could use this as a language learning tool as well.
Trying to make my Rust library `composable-indexes` more ergonomic. It is for indexing a collection on multiple dimensions in a type-safe and composable manner.
In other words, something safer & more concise than maintaining multiple HashMap's, but a lot less involved & simpler than an in-memory SQLite.
The first business I started never gained traction, so I sold it in 2021 (which was a completely different time compared to now).
Notion had announced that they'd launch a beta version of their API, so while waiting for the early access, I built a landing page, login/signup, and all other plumbing for the web app.
It was a rather underwhelming launch (both for the API and my business), but I gained my first customer within a month.
Honestly, it's been a slog running this business (Notion's API is surprisingly hard to work with, so it seemed that I was stuck for months on end), so knowing what I know now, I'd probably have started a different business. My burnout didn't help either.
Claude has been incredibly helpful these last few months in solving esoteric undocumented edge cases that were plaguing the codebase for years.
I have a healthy MRR/growth rate right now and the biggest product in the niche, so I'm grateful for that.
Currently doing the finishing touches on a ww2 era surface grinder, closing out a new little design, and ramping my fitness up again. Next up is some duct work, some reverse engineering, and finishing my part of a paper.
I haven't had this much time off in over a decade and it's amazing. I've been hoping to get inspire for some outdoors or running related mechanical design/prototyping projects, but nothing yet.
Feels like I'm working on a million things (between work, side contracts, and creative explorations). Recently a friend asked whether AI is helping or hurting my workflow.
And I realized I couldn't give a concrete answer. Lots of speculation, but I realized I didn't have hardly any real data. Inspired by Adam Grant's work on "rethinking", I'm _currently_ writing a tiny CLI to run self-experiments on my own productivity, auto-checking in / observing commits/code changes.
Goal at the end is to be able to test myself across different dimensions with "no AI", "moderate AI" (e.g. searching, inline assist), and "full AI" (agents, etc).

Working on a flight tracking tool that records the landing and takeoff actions of a local airfield to get insights in how they determine on which runway a takeoff or landing is assigned. Problem is that all the free aircraft api's don't register a landing or takeoff act and also not on which runway.
The airport in question has just one runway and is situated in a dense population area. Both sides of the runway are used (officially noted as two runways) for takeoff and landing causing noise complaints in the neighborhood. The airfield says it assigns a runway based on wind direction and speed, and when there is much traffic they relieve one of the two directions to prevent going over a threshold. My goals is to check if they follow their own rules and just to have a insight if my annoyance over why there are so many aircraft over my house and not on the other side is justified or not.
As a frontender this is quite challenging. I'm using Express with typescript to write the backend. Usually I get bored quite quickly because progress is not going fast enough, so I'm using a lot of AI to speed things up.
I'm checking for aircraft in a 5km circle every 30 seconds. If a aircraft is below and above x feet than I'm going to track it every 5 seconds. Between each entry I'm checking the coordinates and altitude to determine which runway (direction) is used and if it's taking off or landing. I'm also using another API to get weather data like wind speed and wind direction. Finally this is saved in a JSON file (for now) and loaded into the frontend to be displayed in a table.
I do have a working prototype, and removing a few bugs. At the moment it's checking the logs after a day of collecting to check for errors, fixing those errors and validating the fix the next day. When it's done I'm planning to open source it so that anyone can use it if needed.
I've really enjoyed writing blog posts recently. Not only is it a great way to flex your writing muscles, but writing about a topic, unsurprisingly, helps you understand that topic better too. I've had great conversations with friends about the posts I've written as well.
And sort of in that same vein, I've been developing my own static site generator that I eventually want to move my blog to. It's almost certainly going to be a worse SSG than every alternative, but it'll be mine and that's worth something in itself.
Plus it's just been fun to make! I wrote some gnarly code to generate infinitely nestable layouts that I'm kind of proud of. It's the kind of code that's really cool but you can only code on a project for yourself, because if someone else had to debug it, they might say some pretty unkind things about you.
I agree with you about writing. Back in 2020, I made a commitment to study a CS or math topic in detail each week and then write an essay about it. Those were some of my best learning experiences and when I look back at those essays, they are pure gold.
I crunched Strava data (the Strava MCP project is incredible, and I ended up contributing to it!) and built myself this fitness hall of fame page (and also rejuvenated the remainder of the portfolio). Almost all of the stuff here is vibe coded, very happy how much I could achieve.
i saw the strava mention and I clicked through - this is a super cool project! The maps + visualizations are beautiful.
Something about strava and the data we get from it is really special to me. It's a fun step into a deeply physical thing (moving our selves around the surface of the earth) and renders it in this digital space - a website, an animation.
Working on The Password App (https://thepassword.app) - an AI-powered macOS desktop app that automatically rotates your passwords across websites.
The problem: most people have 100+ accounts with weak/reused passwords. Changing them manually is tedious, so nobody does it.
The solution: import a CSV from your existing password manager (1Password, LastPass, Bitwarden), select which accounts to update, and the app uses browser automation with Gemini 2.5 Flash to navigate to each site's password change page and update them in parallel. Exports a CSV with the new passwords to import back.
Key technical choices:
- browser-use library for AI-driven browser automation (handles dynamic sites better than Selenium)
- Local-only architecture: passwords never leave your machine, no cloud sync, everything stays in memory and is cleared after use
- Electron + Python: React frontend with a Python agent for browser automation via stdio IPC
- OpenRouter for LLM access (Gemini for navigation, Grok for validation)
Security was the most important and the hardest constraint. Passwords can't be logged, can't be sent to the LLM context, and can't persist on disk. Custom fork of browser-use to inject credentials via secure parameters invisible to the AI agent.
Currently at v0.38 with code signing and notarization for macOS. Working on improving success rates - the main challenges are 2FA requirements and anti-bot detection (Cloudflare, reCAPTCHA).
Would love feedback from anyone in the security/password management space.
I noticed that as I'm using agents more and more my PRs are getting more ambitious (read: bigger diffs), and when I was reviewing them with agents I noticed that the first review wouldn't catch anything but the second would. This decreased my confidence in their capabilities, so I decided to make a tool to let me run 10 review agents at once, then aggregate their findings into a single agent to asses and address.
I was using Codex at the time, so Tenex is kind of a play on "10 Codex agents" and the "10x engineer" meme.
I've since added a lot of features and just today got to use it for the first time in a production system. Some rough edges for sure, but as I'm using it any time anything feels "off" or unintuitive I'm taking notes to improve it.
Fun fact, on my machine, while launching 50x Claude Code instances very nearly crashes it, I was able to launch 100x Codex instances no problem. I tried 500x but I ran into rate limits before they could all spawn :(
Getting close to my last day at my current job, and I couldn't be more excited to build in public.
When I moved to Thailand last year, the language barrier hit me immediately. So I’m scratching my own itch and building https://thaicopilot.com/, It's designed to help you learn Thai in real situations. Still early, but moving fast.
I'm migrating my current Google Sheets solution to a web application that I will primarily use for expense tracking and budgeting. I'm learning Golang so this is a perfect opportunity for me to build something meaningful.
Two main aspects will be to do Exploratory Data Analysis and to forecast expenses.
For later stage, I am planning to create a conversational interface for the application that I will use to do basic CRUD operations as well as capability to "talk" to my data and to do simulations using hypothetical yet real scenarios in future.
It was my weekend 1-day hackathon yesterday building Electron-based web browser connected with PlayWright MCP and local Codex as LLM backend.
Yes, you need to be ChatGPT Pro+ to use, because Codex has no usage fee unlike API Key.
GPT-5.1-Codex-Max can handle really complex web task without templating DOM. Codex-Mini is fast so you can pick models. It does my job applying task to any of recruiting sites with no interactions. (with persistent data store, which is currently disabled on published version)
Today is the start of Langjam Gamejam, a 7-day hackathon to build a programming language and then make a game using it. I'm ideating on what I'll build.
Working on promptfoo, an open-source (MIT) CLI and framework for eval-ing and red-teaming LLM apps. Think of it like pytest but for prompts - you define test cases, run evals against any model (OpenAI, Anthropic, local models, whatever), and catch regressions before they hit prod.
Currently building out support for multi-agent evals, better tracing, voice, and static code analysis for AI security use cases. So many fun sub-problems in this space - LLM testing is deceptively hard.
If you end up checking it out and pick up an issue, I'll happily send swag. We're also hiring if you want to work on this stuff full-time.
Most recently I've been having fun extending the functionality on a website I use to host tools that help me structure and plan workouts - https://ironvolume.com/
I’m speed-running a bunch of new hobbies to teach myself how to make a physical game (basically its a ping pong paddle that tracks how often you hit a ball — like a “keepy uppy” game with scorekeeping):
- Arduino dev and circuitry
- 3D printing
- PCB design
- Woodworking
Its all a lot of fun and IMO a lot more approachable than it has been thanks to the assist from LLMs.
Trying to rebuild my website (php mvc built a decade ago) using Django. I want to be able to update any page content, upload and display images, have multiple blog instances. I do a lot of django-cms by day, but it's too much for a small personal website, so I started to create a (tiny, foss) CMS based on Django, django-prose-editor for the content, and some new apps (for now, Page & Blog).
The site isn't even online, but for now I'm starting to think about the next steps (seo-related things to implement, generalize app functions to handle not only blog but other (hypothetical) apps as well, improve code quality and repo readability, separate apps from the website so anyone can add them to their django website if they want to). It's a lot of work for something no one will ever use, but I must at least try to make it clean and discoverable :)
This week I'm taking a break from my next project in this series (celery related) to try to participate in game jam related to programming language creation:
As a means to learn about both WebAssembly and Rust, I started writing a WebAssembly binary decoder (i.e. a parser for `.wasm` files) from scratch.
Recently it hit v2.0 spec conformance. 3.0 is next on the roadmap. (I'm executing it against the upstream spec test suite.)
I don't plan to make it a highly-performant decoder for use in production environments, but rather one that can be used for educational purposes, easy to read and/or debugging issues with modules. That's why I decided not to offer a streaming API, and why I'll be focusing on things like good errors, good code docs etc.
I'd say jump straight to the specification (maybe v2, which is simpler).
But I occasionally saw one or two articles around where they explain how the binary format works, which could be a good introduction before jumping to the spec.
Marketing line: Atom is your conversational AI agent that automates complex workflows through natural language chat. Now with Computer Use Agent capabilities, Atom can see and interact with your desktop applications, automate repetitive tasks, and create visual workflows that bridge web services with local desktop software.
Working on https://canine.sh, an open source, self hosted PaaS for Kubernetes.
A big part of this was inspired by the last startup I worked at. In an effort to not deal with complexities of Kubernetes, we ended up on Heroku and was charged exorbitant amounts of money. One year spending close to 400k on Heroku alone, for what should’ve been 10-15k in cloud costs.
I think a big part of this is just making Kubernetes more friendly and easier to use for a small / midsized team of developers.
The goal is to make it easy enough for even a single developer to feel comfortable with, while also being powerful enough to be able to support a small team
I see that your app/tool is linked on Portainer's website. What's the business model behind it ? I do not see any pricing and I could be really interested as I'm looking for a solution to abstract away k8s complexity for a medium sized company I'm working for.
Yeah it’s totally free to use and there are pricing tiers for support that portainer provides. Canine is 100% FOSS. No hidden features behind some payment plan or anything.
Portainer sponsors us, to keep us working full time on it.
Shoot me a note at chris @ canine<dot>sh
Would love to help in any way I can! Always looking for more adoption, esp at medium sized companies
A browser automation Chrome extension and MCP. It consumes less context than playwright MCP and is more capable: it uses the playwright API directly, the Chrome extension is a CDP protocol proxy via WebSockets.
I use it for automating workflows in development but also filing taxes and other boring tasks
CtrlAssist – an open source project to bring more accessible, collaborative gaming to Linux! Inspired by PC gaming sessions with my own family, where both young and old relish exploring rich stories with immersive worlds (like Witcher 3, RDR3, Hogwarts Legacy, etc) but find coordinated combat or movement control too challenging to play solo, CtrlAssist lets you combine multiple controllers into one virtual gamepad, much like assist features on dedicated game consoles.
Whether your helping grandparents through tough boss fights, or co-oping with nieces and nephews to level age gaps, CtrlAssist aims to make PC gaming on Linux fun and accessible for everyone. While I’m certain similar utilities exist, I also just wanted a holiday hobby project to practice Rust development while scratching a personal itch.
Please give it a try, share your feedback in the relevant discussion categories, or check out the open issues if you’d like to contribute, help is always welcome!

I am working on Correctify's Design Studio, a feature that turns plain restaurant menu text into menu designs based on your choosen size, style and branding.
What makes it different from alternatives is that it’s content-first. Instead of dragging boxes around or fighting templates that don’t fit your menu, Design Studio designs around your text. For restaurant owners, that means significantly lower waiting times and costs.
Design Studio is still in private beta, but excited about where it’s going
I’m working on OpsOrch(https://www.opsorch.com/), an open-source orchestration layer that provides a single API across incidents, logs, metrics, tickets, messaging, and service metadata.
It sits on top of existing tools like PagerDuty, Jira, Prometheus, Elasticsearch, and Slack, and normalizes them into a shared schema. It doesn’t store operational data, it just brokers requests through pluggable adapters and returns unified structures.
The motivation came from incident response workflows that still require hopping across multiple vendor UIs and APIs with different auth models and query languages. Instead of another “single pane of glass,” this is meant to be a small, transparent glue layer.
On top of the core service, I’m also exposing everything via an MCP server so LLM agents can query incidents, metrics, and logs as typed tools without needing vendor-specific knowledge.
Currently open source, written mostly in Go and TypeScript. Still early, but usable with PagerDuty, Jira, Prometheus, Elasticsearch, Slack, and mock providers. Feedback from SREs and infra folks has been very helpful so far.
please don't hug to death, I only got 10 GB of Data
it's 1st MVP and I got a dayjob, so please be kind. Haven't put out a howto yet, but ideally you have a notebook and a pen, some memories and grief to work through.
I'm building out a new concept around training AI computer use agents on real sensitive tasks without PII exposure. My first demo releasing soon is a dataset of AI agent with human assisted tasks on things like paying my personal credit card or doing bank transfers.
Main things:
1. I don't modify the website I operate on
2. I take full videos and record all AI agent logs and all human actions
3. I don't modify any of those logs and will release them to the public.
I am working towards a future where AI companies are paid to generate the data they need for AI agent operations instead of paying massive sums to generate synthetic data. Imagine a future where labeling companies are completely sidestepped by simply training on production tasks directly.
An agentic media player, intended as home media server for.. uhh.. seasonal vacation videos with subtitles. I've experimented a lot with different "levels" of AI automation, starting from simple workflows, to more advanced ones, and now soon to fully agentic.
Pretty good practice project! All written in Go with minimal dependencies and an embedded vanillja-js frontend built into the binary (it's so small it's negligable)
Hey all, I am a noob at building my own things. Recently, I have started building my own web app, which collects AI related news worldwide. I also cluster them to identify trends within the AI economy. This was interesting to me as I do actively invest in stocks. The website also generates a newsletter, collects details related to new corporate deals announced, etc. It is collecting everything related to AI and the economy.
Now I feel lost, I don’t know where to go from here. I don’t even know if I am doing the right thing. What do you think? Is there any guidance or roast you can give? Here is the website https://www.racetoagi.org/
A tool for searching, filtering and chatting with the "What are you working on?" posts. Also has a visual map (UMAP) that clusters similar things together. Useful if you want to find specific things or better understand themes.
Working towards a handheld computer with a physical keyboard. Lots of examples out there (Hackberry Pi, Beepy, etc) but wanted to try my hand at it.
Along the way I found most of these use salvaged BlackBerry keyboards which are only going to become harder to find, so also on a bit of a side quest to build a thumb-sized keyboard from scratch. Got me into laying out and prototyping my first PCBs and learning about how these things are made - lots of fun so far!
Something cool I learned from tearing apart a BB keyboard: the satisfying “click” is just a tiny metal dome that pops and completes the circuit when pressed. Not news to anyone familiar with electronics manufacturing, but it was a cool thing to “discover.”
A service that allows you to post generic agent/task workload and execute and observe it in the background. Sort of for long timelines. I just want to have background agents to monitor various aspects of my digital life and keep those healthy, eg check if I’m using all of the tax credits and leverage them to get the most after tax cash, or constantly monitor my network and alert me when something is off, or scan and evaluate my public contributions and remind to post something new once in a while. Just a tool to make sure I am on top of everything.
Using Go on the back, React for ui, sqlite, containers for async work, openai. Trying to keep it simple.
Been casually working on some AI projects lately. Open-sourced both: LLM Archive Downloader. Got paranoid one night about open-source models potentially disappearing (licensing changes, restrictions, who knows). So I built a script to download and archive them locally. One command, pick what you want — Llama, Mistral, DeepSeek, Whisper, the works. ~200GB total or grab the essentials (~40GB). Now they're sitting on my hard drive. Offline forever.
→ github.com/Ashwinsuriya/llm-archive-downloader
YouTube Shorts Generator
Converts long YouTube videos into Shorts automatically. Whisper handles transcription, LLaVA analyzes frames to find interesting moments, Mistral picks clips and writes captions. Everything runs locally in a parallel pipeline. No APIs, no subscriptions. → https://github.com/Ashwinsuriya/yt-shorts-generator Nothing fancy.
Just scratching my own itch and sharing in case anyone finds them useful.
Freight forwarders spend days or sometimes even weeks understanding and answering tenders without even knowing if they'll win the bid!
With Tenderlane, they can now upload the entire tender spec and get an overview of what the customer wants in minutes instead.
One key learning for this project is that I'm using Excel as the "frontend" as this is what our users are most familiar with, so lots of processes involved filling, uploading and downloading an Excel file.
I'm finally wrapping up a little webdav tool that's been on my todo list for years. It's just a simple tool to copy directories over webdav. I tried using Cadaver but I kept running into strange errors with it. And this one ties in with an unusual authentication setup. Might open source it, haven't decided yet.
Also dicking around with DMARC tools. Was unhappy with all the existing tools, want something simple I can run semi-locally for a bunch of low volume email domains. Haven't decided yet how that will turn out, still in the reading specs & tinkering stage.
> Also dicking around with DMARC tools. Was unhappy with all the existing tools, want something simple I can run semi-locally for a bunch of low volume email domains.
That’s a rabbit hole on my list to go down - recently set up DMARC for some domains I am hosting emails for and the XML reports that now end up in my inbox were… refreshing to see in 2025 :)
I’m trying to build 1 decent iOS mobile app per month.
Most recently released one was My Vocab Quest[1], a vocab mastery app with lots of word packs. It uses some gamification mechanics to make sure the user puts in the reps.
Current apps in the hopper are centered around:
(1) Recovery from cosmetic surgery. There are several balls to juggle for days, weeks, and months after a surgery. The app helps the user follow surgeon instructions, promoting physical and mental recovery, as well as medical and dietary changes. Makes use of phone features including contacts, calendar events, notifications. I’m learning to build an App Clip for it and hope to partner with some surgeons to get it promoted in their offices.
(2) Assisting older Americans to be more independent for a little longer (a parent of mine has early stage dementia). Helping the user maintain a regular schedule, take their medications on time.
(3) A dating ideas / meal ideas and agreement app. It helps increase creativity for date ideas, learns from how predictable you are, and facilitates agreement between the users.
Eidetica - a decentralized database built in Rust, intended for local-first apps. It's still unstable but I'm progressing relatively rapidly. In the past ~month I have:
Last night I decided to take a break from the digital world and started on making a guitar. Leaning towards something in the style of Lacôte[0] but not sure, ordered a book on Vicente Arias[1] and might order a couple other plans to consider. Have a fair amount of stock prep to do before I have to commit to a design and will probably need to order a few sticks of wood as well, so probably have ~two weeks to make up my mind.
That last link is almost the entire book, have not looked through the digital version yet but on a quick look I think it is everything but the portfolio of his work.
I created this simple stock management system. This was a good experience building an end to end product since I have been a front end developer all my life, building this has been an amazing experience.
Backwards compatible verified phone calls. Android version is in testing with friends.
2) Katalib.
We have about 1600 books or so at home, there's no chance I'm going to scan ISBN codes of all of these. I've tried four times and got way too bored after the first 100-200. The solution? Take a photo of the bookshelf, send to Claude for text parsing and series information. Then some UI etc around that.
It's working, I just need to start testing it myself and a few friends have also asked for access.
I'm starting the process of photographing everything I own for a potential insurance claim in my high wildfire danger area. I've dreamed of something like this that could name, describe, and estimate the replacement cost of each item, saving me hundreds of tedious hours. Including books. So please think big like Jeff Bezos and don't stop with books.
If visions of wealth don't motivate you, think of how much the insurance companies will hate it.
I am not really working on anything big right now,
mostly just improving what I wrote, in particular
documentation-wise.
However had, on my todo list ... a few things that
are important to me are there.
One is to create some kind of pseudo-language that
can model biological cells, from A to Z. I am having
something similar to erlang in mind (to some extent).
Now, this is nothing new - modeling is quite old,
bioinformatics is old, but I have a few ideas that
are somewhat novel IMO (e. g. really following erlang
here, just adapted to biological systems).
Then I have a few smaller ideas. One is to finish a
webframework where everything is really an object at
all times. Meaning, I can work with objects when
describing a webpage, from A to Z. HTML tags are
objects too. I don't typically use them directly,
though, but more in a meta-layout, e. g. I want to
describe a webpage, but on a higher level, and
also push that down into a .pdf file then seamlessly.
My goal here is to be able to work with objects
everywhere, not just for a single webpage but for
all local and remote webpages, a bit similar to
Alan Kay's old ideas.
I have a couple more ideas (one is the widgets project
where I want to describe a GUI only once and then
have it work in as many variants and languages as
possible), but realistically I also focus on the smaller
things to do as they are much easier to solve. Right now
it is more important to me to finish as much as possible
before the end of the year, so prioritising on smaller
things makes more sense.
I've recently been working on developing an MCP on top of Libreoffice Draw and I just learned what an amazing piece of software the whole Libreoffice suite is, I would definitely be trying to use it more and I will take a look at your extension. Thanks for sharing!
It is! My only struggle is with the extension development/documentation. It was a pain to get my sidebar appearing in the toolbar, and I'm afraid to touch any of that code I wrote.
How are you going about learning about the LibreOffice APIs?
Building Arivu: CLI/library that normalizes fetch/search across a bunch of sources (arXiv, PubMed, HN, GitHub, Reddit, YouTube transcripts, RSS, web pages…).
I use it as a context fetcher i.e grab an abstract/transcript/thread as clean text/JSON, pipe it into summaries or scripts.
Also runs as an MCP server (experimental), so tools like Claude Desktop or CLI assistants can call the connectors directly.
Nothing on the scale of most the things mentioned here, but I'm trying to assemble the first version of my digital garden to publish online a bunch of notes I've collected over many years. I'm also trying to put together a workable system to catalogue and index hundreds of thousands of digital images scattered across multiple devices so I can deduplicate them and collate them effective. Digital Librarian is not a hat I ever thought I'd end up wearing, but I refuse to buy more 18Tb HDDs and still not have any means to locate pictures in a meaningful way.
Trying to grow this newsletter - a roundup of the most votted and commented AI links from HN. After 11 issues I am at 221 subs, most of them from Reddit posts (I post a short description of the top 5 links on several AI subreddits).
Not sure how long this will work, I feel like I spam these subreddits.
I want to launch on Product Hunt soon and maybe add it to some newsletter directories, but I have low expectations.
I post here on HN a link to each issue after I send it, maybe that will get from traction one day.
Enterprise/Organization focused MCP gateway with support for sophisticated credentials management, integrates with OIDC/SAML, team and profiles support, external secret stores (AWS/GCP/Azure/Hashicrop Vault), using envelope encryption, and in-band-MCP authorization trigger for e.g. trying to use a tool which Gatana not yet has credentials for.

Self serve AWS cost savings for Terraform users. Connect AWS (read only role via a Terraform module), GitHub and Terraform state. Infralyst finds underused resources and opens a PR to downsize, gated by best practice checks so it doesn’t suggest sketchy changes.
Free: 3 downsizing PRs per workspace. Pro: $99/mo unlimited PRs. Looking for early users and blunt feedback from teams running AWS + Terraform.
If you try it and mention you came from HN, I’m happy to set you up with an early adopter discount.
I've been working on a weightlifting logging app for the apple watch. I haven't submitted it yet since I am still beta testing, but I'm mostly feature complete.
It's intended to be anti-memetic, and anti-guilt trip. Just put it on your watch, install a program (open format) and you never need the phone itself. Your workout is a holiday from your phone.
The data can be exported if you want to use it elsewhere.
I originally made it for ROCKNIX but as there was no way to share the app I paid the Apple tax :/
I’ve started building a domain-agnostic scientific data archive, inspired by the Protein Data Bank. It handles the deposition, validation, curation, storage, and searching of scientific data, with plugin interfaces for domain-specific components.
The goal is to accelerate AI-for-science efforts by making it easy for scientific organisations to spin-up professional-grade data infrastructure in a matter of days. “PDB-in-a-box”.

My first customer has me looking for e6+ or cloud architects to be paid advisors to review cloud migration RFCs. (No coding) Comp is $1k per RFC you review. There are at least 18 RFCs per month to be reviewed.
Working on my language learning app (Python, tkinter) "Xiaolong Dictionary"[0]
It is supposed to implement all kinds of features, that I usually miss in vocabulary learning applications, such as a very powerful search function, and the ability to add arbitrary tags, a table of words, and learning progress statistics (not yet implemented).
It has minimalistic dependencies. Currently the only non-development dependency it has is jsonschema.
I keep the configuration of the application in a JSON file. This configuration already allows to configure many things, like for example the various learn levels, and what their meaning in terms of the spaced repetition system is, which attributes of a word will be revealed in what order, when practicing, what attributes to show in the columns of the vocabulary table, and what font to use for the big character display widget (useful for languages like Chinese).
It's AGPL, so feel free to fork, but adhere to the license.
The idea here is, one can pick the slides they want and arrange them into a sequence right in the URL. This way, there is no registration, no user data collection, no persistent state even. You just pick the slides, teach your material, and move on.
It's very raw, I still want to add a convenient sequence constructor, a "blank" slide so you could display your own content in it, and a similar quiz page. But I already used some of the slides for teaching, students seem to like them.
Hopefully, I'll have the rest done by the beginning of the spring semester.
I'm experimenting to see if frontier LLMs can do practical CAD modeling. I'm starting with a single task: designing a wall mount for my bike pump in OpenSCAD or CadQuery (two code-based CAD systems).
None of the frontier LLMs (Gemini, ChatGPT, Claude) produce usable designs when just prompted with some photos of the pump and a written description of the mount. I'm now building a simulator in Mujoco that the LLMs can use to test and iterate on their designs to see if they can do better in this setting.
I'm hoping to make an interesting blog post of it and maybe end up with a usable wall mount design.
I’ve been working on Pixie, a platform to employ and track your kids for real work; for families with a business, it helps reduce tax burden and fund a child’s Roth.
I’m actually an anesthesiologist with some 1099 income, built the platform myself because my kids help with my side projects, and have since onboarded CPAs who now offer it to their clients.
It's been a fun journey!
I've been spending weekends thinking about authorization for AI agents, specifically delegation.
The failure mode I keep hitting: once you give an agent tools, it gets ambient authority over all of them. There's no clean way to say "for this task, read-only on the reports table" or "spin up no more than 3 VMs." When the agent spawns sub-agents mid-execution, they inherit full access by default.
IAM doesn't help much. Authority stays tied to the agent's identity even as intent shifts during execution.
I'm exploring a capability-based model instead: authority is explicit, task-scoped, and attenuating. Closest to Macaroons/Biscuit, but adapted for workflows where delegation happens dynamically mid-task.
I came to the same realization a while ago and started building an agent runtime designed to ensure all (I/O) effects are capability bound and validated by policies, while also allowing the agent to modify itself.
I'm working on a meta framework for building "full-stack" libraries. I.e. libraries that bundle frontend hooks, backend routes, and a database schema into a single package.
This allows library authors to do more, like defining webhook handlers and (simple) database operations. The idea is to move complexity from the library user to the author, making (API) integrations easier.
I think libraries being able to write to your database is a pretty powerful concept, and can enable a number of interesting use cases.
I made a platform for innovators, founders, developers to validate their idea against real users (not AI).
My purpose to build this platform is two-pronged–first to solve the "Power Law", in simple terms, where platforms such as Instagram, Reddit, YouTube, TikTok, etc. only put forward the popular content (most upvoted, liked, viewed, trending, etc.) and people who are posting regularly are still left behind fighting for some interactions.
Second, to provide a platform for people, innovators such as myself, who keep asking the question "is this worth working on? worth spending time and money on". There are subreddits with hundreds of thousands of followers and Redditors and many of them are still not getting the visibility they need to start.
I remember that I had a lot of ideas throughout high school but I wasn't able to get real answers and validation from people so I dropped it. So specially for those people who need a little bit more visibility.
Several years ago I wrote an internal tool named Fogbeam Universal Competitive Inteligence Tool (eg FUCIT). It was up and running and doing it's job for a while, then a lot of stuff happened and it kinda fell into disrepair. It's a Grails app and the original Grails version was something like 2.2.3 and I think it was running on Java 1.6 or something along those lines.
Anyway, for a lot of reasons that don't matter now, the time has come to rebuilt | reinvent | reinvigorate this thing. So for the last week, I've just been working on updating dependencies, fixing the resultant breakages, and also fixing miscellaneous bugs that had never been fixed (or possibly even noticed) before.
As of today I have most of the base functionality up and working again. I just got all the Quartz scheduling stuff set back up and now I'm testing the scheduled job that fetches data from RSS feeds and creates associated records based on the contents of those items.
Up next: test|fix some functionality around defining "semantic assertions" about entities in the system (using Apache Jena) and then I'll at least be back where I was.
After that, I have some UI improvements to make (the UI now is basic GSP pages with Bootstrap and jQuery), and then some GenAI integration stuff. Beyond that: who knows?
I did pick up Volume 1 of "The Handbook of Artificial Intelligence" earlier this afternoon and read about 25 pages. I've also been working my way through "Parallel Distributed Processing - Volume 2" and "Principles of Semantic Networks" for the past few weeks, so continuing to grind on both of those as well.
A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use. There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used.
When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.
My Civil 3D plugin will:
1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.
2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.
If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.
As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.
I'm trying to recreate https://viewsourcecode.org/snaptoken/kilo/ but in Zig, will probably have to face shit metric ton of hate after finishing it due to probably some mistakes and sharing them online in form of a guide, but I'm doing it to learn myself, hope that project will improve by people posting issues or simply forking the project when I will finish it.
Upload a CSV or circle neighborhoods on Google Maps to build your address list (consumers or businesses). Printing and postage included in one price.
In the last 30 days I've added an API plus integrations for Pipedrive, Zoho, and Follow Up Boss. If anyone wants to help test these new integrations, I'll set you up on a special plan and let you send mail at my cost (roughly the price of a stamp).
React Native mobile app + React web app that shows all the coffee shops across New York City. The idea is that you can open it and the app instantly displays the closest coffee shop to you. It integrates with Google Maps reviews AI summaries for a lowdown on the coffee shop and vibe.
I'm building https://aero.zip, an E2E encrypted, resumable file transfer tool (think WeTransfer but encrypted and not P2P). I just posted it to Show HN:
* Streaming ZIP: To allow downloading multiple files as a single archive without buffering, I implemented a custom streaming ZIP64 archiver. A Service Worker intercepts the request, fetches encrypted chunks, decrypts them, and constructs the ZIP stream on the fly in the browser.
* OPAQUE auth: I used the OPAQUE protocol (via serenity-kit) for the password-authenticated key exchange. It ensures the server never learns the password and protects weak passwords against offline attacks if the DB leaks.
* Passkey PRF auth: If your passkey provider supports PRF (like iCloud Keychain or Windows Hello), the app derives the data encryption key directly from the passkey, allowing a login flow that doesn't require entering a master password.
From what I understand, croc is P2P, i.e. both computers have to be on for the transfer to happen (the "relay" that they mention only helps negotiate the connection between two peers). With aero.zip, you upload your files to a server, and the recipient can download it whenever - either real-time while you're still uploading them (imitating the P2P/croc model), or at a later date. This is a more universal approach IMHO.
Also, aero.zip is a webapp, i.e. there's nothing to install, and you don't even need to sign up to send small files. Meanwhile, croc is a CLI utility which will be hard to use by mom-and-pop users.
It lets you open links in a side panel, so you can quickly look at a page without leaving what you’re reading. I built it because I tend to open too many tabs when reading docs or search results.
It supports a few simple triggers. My favorite one is long-click: you click and hold a link, and the preview opens in the side panel.
Chrome recently added Split View that you open from the context menu. It works, but for quick checks it feels a bit heavy. You have to right-click, move the mouse, and pick an option.
With long-click there’s no menu. For me it feels faster, more intentional, and better when scanning lots of links.
Most of the work lately is about polishing these interactions and dealing with browser edge cases.

htvend is a tool to help you capture any internet dependencies needed in order to perform a task.
It builds a manifest of internet assets needed, which you can check-in with your project.
The idea being that this serves as an upstream package lock file for any asset type, and that you can re-use this to rebuild your application if the upstream assets are removed, or if you are without internet connectivity.
Has an experimental GitHub action to integrate within your GitHub build, archiving assets to S3.
This week I vibe coded an golem-forge (https://github.com/zby/golem-forge) - exploration of prompting as programming.
Since then I found https://github.com/badlogic/pi-mono and https://github.com/johnlindquist/mdflow and I think I'll rather use these existing tools to explore my idea. But I think it might be still interesting project because it is entirely vibe-coded - I don't even know Typescript (I know some Javascript from before React - but none of the new stuff). I did not look into the Typescript code at all - only at what the LLM presented to me when editing it and the docs. At some point I discovered that when I tried to have a core logic and two UI packages the LLM put only types in the core package - so I had drive a hard refactoring - but it worked.
I haven't yet tried this very extensively - but another profound change in programming that this showed me is that it is now very easy to borrow parts of Open Source libraries. It used to be that you could only base your work on a library - borrowing parts of projects that were not designed to be shared (used as libraries) was prohibitive - but with llms it is entirely possible to say: "now please borrow the UI ideas from project X" and it does that. Maybe you need to add some planning.
I'm working on https://wireplug.org:
A simple, free, and open source connectivity coordinator for WireGuard.
Basically a way to keep WireGuard tunnels connected while moving between different access points.
It handles (basic) NAT traversal and works with the in-kernel WireGuard driver on Linux and OpenBSD.
I finished the library providing all features of a multisig file signing scheme. With that it was easy to develop a cli tool. And now I'm looking at developing the server component.
Looking forward to share a complete solution! Git backed, decentralized, no account creation needed (auth by key pair), open source and self hostable!
I'm trying to make a neural audio codec using a variety of misguided methods. One I am using ESNs wrong spreading leak rates in a logarithmic fashion acting like a digital cochlea. The other is trying to do the same with a complex mass-spring-damper system to simulate the various hairs of the cochlea as well. Both approaches make super interesting visuals and appear to cluster reasonably well, but I am still learning about RVQ and audio loss (involves GANs and spectral loss). I kinda wanna beat SNAC if I can.
I’m working on a community-driven website for finding local deals, especially happy hours, in Seattle, Washington: https://seattlebardeals.com/. I launched last week on Seattle Reddit and got a lot of positive response. The long-term goal would be to have something like this in every city, so when people are new or are just visiting they can find fun things to do on a budget

Just wrapped up the latest build of Bedtime Hero - an application (React-Native, ios, android) for parents to build/generate bed time stories with their little one. Allows the parent to use pre-sets or set their own and then generate a story (complete with images).
This was a satisfying project mostly because I dog-food it every night with my little one.
Mostly been working on tier6 [0], which is "like" zerotier but over the sanctum protocol and fully open source (ISC licensed).
Getting ready to release a 1.0.0 of sanctum [1], after almost a year of internal testing, dogfooding and talking about it at security conferences.
We've also setup conclave [2] as an official release site for the projects tied to sanctum such as tier6, or the library implementation of the protocol etc.
Started working on an application to make it easy to see what parcels in NYC are upzoned with the City of Yes[1] changes that were passed last year.
I started off trying to make it a service to help people who are interested in ADU's get connected with architects/ contractors but spent a lot of time working on the interactive map to explore related ideas. The site is here buildbound.xyz and map here buildbound.xyz/map. Right now for example, it's very hard to tell if your site qualifies for the TOD upzoning portion of the City of Yes so maybe there is room to crunch those kind of numbers and provide it as a public service.
Trying to decide to keep going down the ADU route in NYC, even though the market is really early here, expand to NY State/ California where the ADU market is a bit further along or keep doubling down on making the best interactive zoning/ land use map in NYC and see if there is any product market fit to be found.
It looks inside each file to see what it’s about, then moves it to the right folder for you.
Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.
It works in 50 languages (including English, German, French, Spanish, Swedish) and with images (OCR and object recognition), PDFs, Microsoft Office, ePubs, text, Markdown, and many other file types.
If you have messy folders anywhere on your Mac, Floxtop can help.
This looks very interesting and I appreciate the pricing model and lack of cloud. It wasn’t clear from the site, but is there a check all moves prior to execution function? Undo?
There is no automatic execution — nothing is moved without your confirmation.
Floxtop suggests the top 5 destination folders where a file could best belong. You stay fully in control: you can choose one of the suggestions, move files individually or in bulk (Move All), or select a completely custom folder location at any time.
If you change your mind, you can Undo per file or use Undo All to revert the entire operation.
I built Codeboards, a developer portfolio that updates itself automatically from your GitHub, StackOverflow, LinkedIn, and more.
Most dev portfolios are outdated, manual, and painful to maintain. GitHub alone doesn’t show who you are. LinkedIn is noise. Personal websites die after 6 months.
I’m working on a modern transactional email API platform. Developers can bring their own AWS SES keys and freely use their own domains for sending emails.
I’m building it on Cloudflare Workers with advanced tracking, modern templates, and advanced webhook integration. Developers can also configure and schedule advanced workflows for their specific needs
The users can review their usage and performance using an intuitive dashboard.
Email is a crowded space and this is my first attempt at doing something indie at this scale.
Wish me luck!
Working on turning individual disparate services into a unified zero-trust overlay network (what we're calling a Synthetic Environment™) where mocks and real services can be integrated or work seamlessly together, accessible through traditional networking or exposed public tunnels.
This is a developers tool, that can be used during development to seamlessly integrate mocks and changes into existing systems. Or easily expose internal work through a public tunnel. Or if been in an position where its hard to push to staging, pre-prod or other environments because of many competing constraints, then this product may help.
Working on https://ottex.ai/ - BYOK alternative to Wispr Flow and Raycast AI shortcuts.
I love global voice-to-text transcription (especially when working with Claude Code or Cursor) and simple AI shortcuts like "Fix Grammar" and "Translate to {Language}".
I realized I was spending around €35/mo (€420 a year) on two apps for AI features that cost just pennies to run.
So I built Ottex - a native macOS app with a tiny footprint. Add your OpenRouter API key and get solid voice-to-text using Gemini 2.5 Flash, plus any OpenRouter model for AI shortcuts.
I've been working on a personal project, from absolute zero to marketing, and it's been a great journey.
Mastering interviews and the most common questions, practicing all the questions to ace them, of course with AI and a lot of language chaining. Real time feedback, complete analysis of interview too. https://intermock.com
Volatility regime models (Markov-switching GARCH, regime-switching stochastic volatility) are ubiquitous in finance. However, they share a fundamental limitation: regimes are identified ex post from return dynamics, providing no predictive power for regime transitions. The standard approach fits a Hidden Markov Model to returns, labels high and low volatility states, and estimates state transition probabilities that are essentially unconditional averages. This matters because the economic value of volatility timing depends entirely on predicting regime changes before they occur. A model that identifies regimes only after observing the returns is useless for trading volatility.
Existing research documents regime-dependent behavior but does not identify causal drivers of regime transitions. The papers on volatility forecasting factors, variance risk premium dynamics, and market instability from option flows dance around this question without directly addressing it. The recent work on causal ML in finance (double machine learning, causal forests) has focused primarily on equity return prediction rather than volatility states. The connection between options market variables and subsequent volatility regime transitions has not been rigorously established through causal methods.
We develop a causal framework for volatility regime prediction using option-implied variables as potential causes of regime transitions. The key insight is that options markets are forward-looking, so information embedded in the implied volatility surface, put-call ratios, option order flow, and term structure slopes may causally influence future realized volatility regimes rather than merely correlate with them.
My biggest project is still Materia[0], a tool for deploying applications with Podman Quadlets. This month I presented it to the Podman User Group's community meeting, which was pretty exciting since I've never presented in a community setting like that before. Otherwise I've been trying to focus on bugfixes, minor feature additions, and working with user feedback so it's not just me fixing my own problems :) . The latter is really fun since I've already run into someone using it in a way that's very different than how I'd imagine it.
Not coding related, I've been on what I've been calling "The Grand Project" for a bit over a year now where I listen to every single album I own (around 855 albums/singles/eps/etc. As of this moment I'm at 828) at least once. It's been a real trip essentially going through my whole life musically and I'm hoping to write a blog post somewhere about it.
This is _very_ smooth and really well done. I've only played a bit of the Solitaire but it's really nice on both desktop and mobile.
I'm curious why you're rewriting it for a fourth time? Am I playing version 3 or 4 right now?
Two potential suggestions:
1. You save the game on pause / tab close, it means I'm not able to continue from another device. Would it be possible to provide some form of "seed" that I could input in my other device to continue where I left off? Not sure if that's even possible, just an idea.
2. Option to toggle between mobile/desktop style cards. I understand the desktop style ones might look a bit small on mobile, but I would prefer it.
I am working for a while on a command line game about spacepirates playing basketball across the galaxy. The game is a basketball managerial game with some pirate-y stuff. It's a P2P game with no central server, built on top of libp2p.
It runs as a terminal application, meaning that you just need to run it from your terminal, but you can try the game over ssh without installing: `ssh frittura.org -p 3788`
Building an app that scans file systems prior to being migrated into M365. Looks for common governance issues and file and folder trees that won’t play nice in SharePoint. Not a migration tool as such, just something to scratch a consultancy itch. Python and Tkinter for now until I hit something that requires more complexity. Also a command line version that I’ll use more often. This probably could have been a PowerShell script but this is more fun.
I’ve been playing around with the Whisper models for a few years now. Last year I had an idea about how to run Whisper Large v3 in real time. That idea became ScribeAI.
Because the quality of transcripts was so high, much higher than I could get with Parakeet, I started to think about how it would serve as a good input for live translation. I played around with this and was surprised by how good the results is, I’ve used it to follow along political speech’s from foreign leaders and other content I’d have just never been able to consume before. You can translate by bringing your own LLM service API key or using the inbuilt Apple Translate models (for a completely offline experience).
A side project for my side project: I built my own static site generator with React islands architecture and MDX support, using Bun. (Build your site from .mdx files, output only html+css, progressively hydrate the client with React only as needed).
> Staring at the errors in my CLI, I realized I did not want to use another framework. It's why I had already discarded the idea of switching to Astro. Twiddling around someone else's abstractions and incentives, frustrations fitting together the final 20% of a project... I've been down that road too many times before. It's never fun. The tradeoffs _you don't know you're making_ are the biggest risk.
Working on Chorebound - an RPG-style chore/habit app. You do real-world chores, they become quests, you fight monsters, get loot drops, earn XP/gold, and level up. Can be solo or co-op with friends/family.
If you’ve used Habitica and bounced off, this is meant to be more lightweight, simplified, and focused on closer-knit co-op rather than public guilds.
Currently working on Klugli - Educational app for German primary school kids (Grades 1-4).
Parents set up accounts, kids log in with simple codes and work through curriculum-aligned Math and German exercises. Built with Elixir/Phoenix/Ash and LiveView.
The hard part isn't the tech - it's creating content that actually maps to the German school curriculum rather than generic "educational" fluff. Currently grinding through grade 2 math topics.

I’m building a simple direct booking link for hospitality businesses that already have demand and want to avoid marketplace booking fees.
I wrote a Telegram bot for video/image translation, and also Firefox/Chrome addons to help translate web content with smart content extraction and non-breaking layouts.
The Firefox addon/Chrome extension is free, but you need your own OpenRouter/Gemini API key. The cost of web translation is really low, you can translate an article for ~$0.01 with really good quality. (You can try at https://addons.mozilla.org/en-US/firefox/addon/subly-xyz/)
I built it because I use Firefox the most and it seemed like no translate addon was good or simple enough. Chrome translate kinda works, but the quality is so low; it usually doesn't understand the article context.
I've been working through advent of code using my own little compiler/language. It's in such an early state that some creative problem solving is required, not to mention the compiler bugs! But I'm very pleased to have it running interactively on my blog like this – I want to work towards some bigger notebooks in the style of explorable explanations.
* The immediate-mode "every tick I ask you for a VDOM based on the user-defined state" TUI framework has all the fundamental features, I think; writing docs and expanding the library of components it ships with. https://github.com/Smaug123/WoofWare.Zoomies
* Decided I needed a nice text display widget, so got side-tracked into implementing the Knuth-Plass paragraph layout algorithm; it currently functions but is buggy. https://github.com/Smaug123/WoofWare.KnuthPlass
* Finally starting to put proper effort into the LLM integrations into my workflows, writing skills, defining the Gospel According To Me to try and poke the LLMs into the right basin - with limited success so far. https://github.com/Smaug123/gospel
Nonoverse: an iOS logic puzzle game (nonograms!), I’m working on adding a new batch of levels. I’m considering a garden theme for extra cosy vibes, but I’m still in the planning stage and drawing assets right now (in inkscape, no AI).
Also PolyGen, an app for “low poly” wallpapers - I’ve sent an update with bug fixes for latest devices and iOS versions; it’s currently being reviewed, when you read this it might be live.
Building https://lenzy.ai - helping products built around chat with AI (think Lovable or Cursor) reduce churn and prioritize product improvements by analyzing their user's chats.
I started about 2 months ago, found 2 early adopters and focusing on making them really happy.
As an engineer working on networking and fiddle with various networking OS on router and switch, I finally port my favorite fd.io vpp to darwin platform and built a app to management multiple VPN/Proxy in one profile.
Also in this project I start writing some rust code with many years experience in C but rust's memory and high performance really impressed me a lot.
Currently working on my own education by learning C from Antirez's C course on YouTube.
I've been working as an ERP developer for a couple years now and the job is so dull and boring that I'm already starting to feel stagnant. So, I am learning more advanced things now in order to: 1. Advance my career, and 2. Maybe code some linux tool (for personal use only, for now!) and stop looking at enterprise code.
Ooh very nice. Going to keep an eye on this, because while qlabs is nice, it certainly is up there in price for some features I require. Just had to spend nearly 100$ on renting it for this week!
Any plans on supporting video playback and rudimentary keystoning? The audio features in qlabs are alright, the video is its killer feature that similar software often touted as alternatives lack.
For the last 3 years, I have been working on a web tool to help me at work: debugging ASN1-encoded data (keys, certificates, Kerberos/CredSSP/SPNEGO/etc data structures, and more) and performing various cryptographic operations. This app is available online; you can try it [0] (no sign-in/up needed).
This December, I reached a huge milestone: I implemented ASN1 tree editing [1]. Now I can edit the ASN1 tree directly in the browser (read my blog post for more details: [2]).
I'm happy that I wrote this tool. I use it often to help me debug my protocol implementations and/or debugging. I know that some of my friends use the JWT debugger and ASN1 parser from this tool. Maybe some of you will find it helpful too.
Porting/reimplementing a Tcl interpreter from C to Zig, based on the design of Jimtcl. This is one of those sub-projects that started due to another project (folk.computer in this case). The biggest difference is thread-safe value sharing, and (soon to be) lexical variable capture.
But why? Right now folk.computer has about a 20% overhead of serializing and deserializing values as they get sent between threads, and it's also meant we can't sent large amounts of data around. I previously attempted to make the Jimtcl interpreter thread-safe, but it ended up being slower than the status quo. So, I started hacking on a new interpreter.
Commands evaluate, basic object operations are in place, but there's still a ton of work to do in order to implement core commands. It may even be good enough to swap in some day!
Puzzarium (https://puzzarium.com), a platform for MMO-style logic puzzle games. I justed launched Every 5x6 Nonogram (sequel to Every 5x5), a collaborative game with the goal to solve every 5x6 nonogram puzzle board.
I’m building an open-source Electron desktop app for managing Claude Code, allowing users to configure various settings on user/project level, setup MCP servers, subagents, skills, see usage metrics and more https://antonbelev.github.io/claude-owl/
We’re building the Browserbase for mobile - Android & iOS at agentic scale with no concurrency limits.
We run them on bare metal without VM brittleness, fully GPU-accelerated with WebRTC streaming using hardware encoder. As good as it gets and it’s amazed every single person who tried it.
Still behind waitlist, give me a heads up at hello@limrun.com to try it out.
I'm working on adding features to the snakemake aws batch executor plugin. The existing plugin supports execution on AWS Batch by dynamically creating job definitions based on rule resource configuration, but was missing support for features like using different containers for different rules, consumable resources, secrets, etc. Two approaches:
1) https://github.com/radusuciu/snakemake-executor-plugin-aws-b... (my fork). Just add the features to the batch job building code
2) https://github.com/radusuciu/snakemake-executor-plugin-aws-b.... This is more experimental and not yet fully working. I wanted to try a few things. a) can we rely on existing job definitions (managed through IaC instead). b) can we implement a fire-and-forget model where the main snakemake process runs on Batch as well? c) Can we slim down the snakemake container by stripping off unnecessary features.
I’m finishing up a language identification model that runs on cpu, 70k texts/s single thread, 13mb model artifact and 148 supported languages (though only ~100 have good accuracy).
This is a model trained as static embeddings from the gemma 3 token embeddings.
A hobby language called OAF (Oops All Functions). Everything is an argument of a parent function PROGRAM. It's very cursed but it's now fully competent as a general purpose language.
Still experimenting with data productivity tooling that doesn't rely on YAML. Been refocused on CLI tooling as a good interface for agentic use recently since Claude Code has gotten so good. Need to do some empirical evaluation on MCP/CLI success rates.
I am working on Grog, the “grug-brained” alternative to Bazel. A mono-repo build tool where all you do is provide your build commands and interdependencies and the Grog will run everything in parallel with aggressive caching.
Yesterday I released https://npmdigest.com, a micro-SaaS to work around the frustrating experience of getting spammed by npm emails "Successfully published X" whenever I release new versions of my packages.
I’ve been building a crypto market visualization and simulation tool because I kept running into the same problem:
TradingView is great for charts, but it’s hard to answer simple “what-if” questions like would rotating into another coin actually have helped or did trimming and buying back improve outcomes, or just feel good in hindsight.
So I started building tools that simulate these scenarios directly on historical data. For example:
- flipping from coin A into coin B and back again over a chosen period
- selling part of a position and buying back later after a drawdown
I’m still early and adding ideas as I go, but it’s already helped me questions I had.
I'm working on a tool in golang to handle requesting access to private and sensitive databases in Postgres. The goal is to help orgs reduce handing out long-lived postgres creds with broad permissions.
The flow is you declare the databases and tables you want to access and the specific permissions you want, an operator reviews it, if accepted it generates a temporary postgres user with those permissions you need. Also, all the connections to the database are proxied through the app, so the domain name and port are random and short-lived, so you don't expose internal database hosts. As an extra, all SQL statements during the user sessions are logged if you want to see that.
I just put something similar together but then on top of Openbao which generates temporary credentials/roles for Postgres. I created a website where people can request access and a specific group of people can approve the approve. After being approved, the database users can request temporary credentials in OpenBao for a specific number of hours.
It’s a meditation app where an LLM guides you without the usual back-and-forth chat. You set your preferences up front (style, duration, focus), then it delivers a structured session end-to-end.
I have a long list of ideas and features to try, but right now I’m focused on feedback. The app is live on the App Store, and I’d love input on:
• What would make you try an AI-guided meditation app (or avoid it)?
• What settings matter most to you (duration, tone, technique, background audio, etc.)?
• What would make the guidance feel trustworthy and not “chatty” or generic?
If you’re willing to test it, I’m especially interested in first-session impressions and what you’d change to make it something you’d actually keep using.
This is the second app that I’ve tried with an AI voice for meditation. And frankly it’s off putting. The voice is great for other settings. But when my eyes are closed and I’m focused on nothing but the voice it stands out as negative.
Now I may tolerate that if you are significantly cheaper than the alternatives but that doesn’t seem to be the case.
I've been a long time Windows user (20+ years) who heavily uses WSL 2 as my dev environment with tmux / Neovim but I'm switching to native Linux before the end of this year.
I tried once 7 years ago but ran into major audio issues that were a deal breaker but I'm hoping the Linux kernel has improved. I have the same hardware as before.
My dotfiles have been public for many years and can 1 shot a new or existing system in a few minutes with a bunch of command line tools on Debian, Ubuntu, Arch (with or without WSL 2) and macOS. It has an install script and theme switching for a long time which I've used to set up a a few systems (personal desktop, laptop and work laptop).
I've been casually tweaking a laptop running Arch with niri. I'm preparing a bunch of things in my https://github.com/nickjj/dotfiles to prepare for that push which will work on Arch Linux and be opt-in to install and configure a GUI and assorted tools.
LLM-driven narrative game. Main technical issue is how go do compaction. I’ve devised a memory hierarchy that compacts the story to a constant amount of tokens per layer. Arc -> Scene -> Moment -> Line. Not sure if that’s the right dimensions to decompose into. Also tinkering how to get the right amount of “divergence” for story progression option generation. A lot of unanswered questions…
Right now I am working on fixing my PC because it is randomly restarting out of the blue during a video call, or during some coding or when it is left unattended. Highly annoying. Right now I basically ruled out anything but the ram and mobo which would be very costly to fix because of Open AI shenanigans.
Working on a little project to make Spotify recommendations better.
You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.
I did (with the help of GPT) a simple script to deploy my Django+Celery projects to DigitalOcean. I was a bit afraid of that in the past, but now it's just a script that, after configuring a few variables (IP, etc), runs smoothly and gives me a perfectly deploy for a side project on a DO droplet. And also I can run again to just deploy a new version.
For most people this is silly but I am super happy that it works.
I am working (mostly vibecoded) a Git history explorer in Go+modernc.org/Tk9.0: https://github.com/thiagokokada/gitk-go. It is heavily inspired in gitk, this is why the name and usage of Tk for the interface.
The reason for it was because after testing multiple Git history explorers, I still think nothing beats the gitk. Sublime Merge is probably the only alternative that I would seriously consider but I don't really like the UI and the fact that it is proprietary (I am not against proprietary software but I prefer an opensource solution when available). Other alternatives have some bugs or the interface few too slow. gitk itself is mostly fine, but sadly it tries to load the whole repository in memory and this is causing issues every time I try to navigate through nixpkgs (I can see the memory consumption going through the roof while the UI slow down to a crawl).
gitk-go loads a batch of commits (1000 by default) and once you get at the end of the list it loads more. I also add a few features that I miss from gitk, for example if you do any change in the repository (change branches, add files to stash, etc) it will automatically reflect in the UI.
Again, the code is mostly vibecoded since this is the first time I decided to try this from scratch. The code works well for my use cases and it is enough to replace gitk for me, but I can't guarantee there is no bugs and the amount of tests are small. But still, it was fun to see something that I wanted to create for a while (I had this idea for a long time since the issues with gitk that I was having) finally taking form. Probably the program is not useful for anyone but me, but if anything this is a feature, not a bug.
It’s “Hotwire for command-line apps”, meaning you can ship a CLI in a Rails app without building an API. The dream is to make it work for all major web frameworks.
Terminalwire streams stdio, browser launch commands, and a few more things needs to ship a CLI for a SaaS quickly.
The best part is when you want to ship a feature for the CLI, you don’t have to worry about pushing out updates to clients and making sure it’s compatible with your API.
A more interesting development are companies that are using it as a replacement for MCP in AI stacks. They’re reporting less token usage and better overall results.
I am working on a little browser extension to copy github pull requests into the clipboard to share them in chat apps for reviews.
I am used to manually ping people with the link and found that having the pr title and the link format github uses makes it easier for people to understand what they are about to review, and potentially makes for a quicker review :).
I'm working on a beginner-friendly online programming language for teenagers who want to learn to code. I think there is not a clear enough winner for what teenagers should do after they learn Scratch so I am trying to make it.
I saw this shared recently. The site presents nicely, and I agree there's a gap there. As a university professor, the story of my students' learning has pretty much been; Scratch, some Python, and then they pick up whatever early-college curriculum is. There's a strong preference for scripting languages like Python and JavaScript.
When you say "what teenagers should do after learning Scratch," what do you mean exactly? Should do to what end? How would Easel present as "the clear thing" they should do? I suppose Scratch wasn't really chosen by these young people; it is obviously simple, and has the prestige of MIT. Schools followed suit.
You're in a different situation, where you have to meet this market in the open. When I visit your site, I am met with code. It's not apparently simple, and a beginner wouldn't be able to distinguish it from any other games programming framework. I think it's actually scarier-seeming to a beginner than something like Godot's scene editor, where you can just drag images from your disk into a prototype-view of your game-scene.
I hope my plainness in stating this isn't taken as an insult. You've got so much work there, and the site is impressive. I also care about this topic, age-range and the learning process, so I'm trying to be helpful with my perspective.
Thank you and I am pleased whenever someone engages and gives me their honest thoughts, it is always helpful.
Maybe I'll rewind a bit, and I'm sorry if this is a long post!
I've just had a teenager who finished making a Chess game in Easel after about a month's work, his most advanced programming project so far. This teenager started in Scratch, has done some Python, but the language they have spent the most time in has been Easel. I've also had a couple of teenagers who have said things like "I suck at coding" and yet make spend months making these quite sophisticated Easel projects full of coding. These two teenagers also did a bit of Scratch but also were lost and disengaged when it came to Python. This mirrors what I've seen in Code Clubs as well, where teenagers just lost interest when shown Python.
Eventually, if someone is going to learn to code for real, they must make the transition from a visual programming language to a text-based programming language, and I know that I have seen teenagers get lost attempting to cross that gap. There are teenagers who obviously have had no trouble with this and that's great, they should go straight to Python or JavaScript or whatever is their heart's desire!
The difference between Scratch and most other programming languages is more than just visual vs text-based. Scratch is actually this cool concurrent, asynchronous, event-driven programming language. This makes it easy to write things like "wait 0.3 seconds" then "move 2 steps to the right". Most other game engines, including PyGame and Godot, instead use a frame-by-frame model. This means you often have to code things as state machines, where you pick up and put down state so that an entity can remember what it was doing next frame. That example of "wait 0.3 seconds" then "move 2 steps to the right" would require the control flow to jump up and down the codebase between state and logic, which means the shape of the code no longer mirrors the step-by-step of what it is actually doing. I think Scratch is successful not just because of its visual coding, but because its programming model allows for step-by-step logic to look like step-by-step code. There's no reason a text-based programming language couldn't also have this property.
Easel is concurrent, asynchronous, event-driven, like Scratch, which is why both Easel and Scratch code can be written in this sequential step-by-step way that you can't easily achieve in other programming languages.
Why can't you just write `await sleep(0.3s)` in other programming languages? Their issue is you can't cancel an `await`, which means it is easy for an asynchronous task to outlive its entity and so they are not safe beginner-level constructs. Scratch solves this implicitly because all scripts are part of a sprite, and when your sprite is removed, all its concurrent scripts stop. It's so intuitive that it doesn't really need to be taught. Easel has a similar thing but in text-based form - it is a hierarchical programming language and everything inside of an entity's block`{ }` gets auto-cleaned up when it dies, including all asynchronous tasks belonging to that entity. I think that's why in Easel, I've seen teenagers spinning up hundreds of asynchronous threads all the time without any problems.
All of this is to say that Easel is like halfway between Scratch and Python. It keeps a lot of the intuitive parts of Scratch's cool programming model, but in text form. My hope (and we have seen this already a few times) is that it can help more teenagers cross the gap from visual coding to "grown up" text-based programming languages.
The reason the code sample is at the top is actually because I saw a teenager talk aloud as they were reading that code and understanding it in real-time. It was super cool because that's it, that's what I've been trying to do - make a text-based programming language that is legible to beginners and not convoluted. And I'm trying to figure out whether it is possible to replicate that moment over and over again with new teenagers.
There is a lot more to it. Easel adds a lot of other stuff like a physics engine and automatic multiplayer. But this post is getting long so I will stop there. I really appreciate the thoughts. I am definitely going to be thinking about how that homepage is presenting itself and I think it is fair what you say that it doesn't look simple, and doesn't look different to any other game engine. That is very good feedback!
Interesting. I admit I have to put my prejudice away to accept that in this case a programming model focused on events is probably good for the reasons you're stating, since those sorts of instructions you want to support, because those kids got their start on Scratch. Well you're definitely doing the right work in just making appealing games with it. Learners want to feel like whatever they want is possible, even if the "whatever" isn't yet well-formed. Your bee-line game is a really fun toy.
A web app platform written in Rust with the primary focus on zero-dependency apps and using Pingora as a forward and reverse proxy. Targeting Hetzner for hosting and Cloudflare for DNS. I love Rust but don’t like the long compile times which led me down this rabbit hole (zero dependencies make for fast compiles).
I'm working on brand new type of collaborative whiteboard that allows anyone (or team) to drag-n-drop items from their devices onto the board.
The problem I'm solving: On a team, people and their files are scattered everywhere.
Solution: A canvas that attempts to open (and edit) as many file types as possible (images, xlsx, pdf, docx, cad). This means you can have people and files on the same page.
It's the only whiteboard that can natively render docx and pdf so far; these can also be edited directly on the board without having to use dedicated software.
It has a built-in Drive where you can store/backup files that syncs across your devices.
There's a few widgets such as Kanban, sticky notes, cards.
And of course, there's agentic LLM (Gemini 3 Pro) that can take actions such as viewing the board, reading documents on the board, and editing items on the board. For example, you can tell it to read a pdf, then write a spec sheet (in docx), or create tickets on a kanban.
I'm launching a private beta next month if anyone is interested in testing it out and giving feedback.
It's based on my simple web app to learn Korean vocabulary. I'm taking elements from Anki and other language learning apps, but making it focused so it works well in a broader language learning journey.

You could create a browser extension that normal users could install such would warn them of a phishing site or email from that domain. It would be 0 cost since you already have the data.
I’m working on Reflect [0], it’s a privacy-focused app for self-tracking and self-discovery. You can track metrics, run self-experiments, set goals, view correlations, visualize your data, etc.
It's a way of working/tools for working with an LLM that allow you to track decision tree graphs, have the robot make more informed decisions and build its own logical chain for history keeping, and modeling all the work as a DAG of events, goals, outcomes, decisions, and observations that network together to allow you to work better/smarter/faster, giving it a living and recorded memory and ways to explore all this.
It's easiest to check out the short demo on the site.
It also links to the live graph of how the tool has built itself.
Really interesting to see, because about 2 months ago I had a very similar idea, just with a bit more opinionated shape of the graph and context building, but more focused on the research and decision-making part. I started the development, but my focus eventually landed on a completely different aspect of that system.
So I have to ask, how well do you see it performing so far with regard to actually sticking to the data present in the system? Do you find the AI agents to adhere properly to the existing data?
On a similar note, can the "consensus" of the system be adjusted in a way where we keep the knowledge which was true at time T (decision provenance), but we avoid having that bit of information affect current decision making?
Cool name, with both hints at "decid[e]" and the graphs.
I'd be interested in integrating this with bug systems of decisions / goals, with actions being comments on those bugs (for work purposes) instead of having a custom deciduous-only DB.
Is this meant to be open source? I don't see a LICENSE.
I'm working on Bloomberry, an alternative to Builtwith for finding companies that use a specific tech vendor/product/technology. Unlike Builtwith, it focuses a lot more on technologies that can't be detected solely from the front-end (ie devops tools, security products, CRMs, and ERPs)

https://medcompass.tools/rankcompass. Might adapt to other avenues to help people pick housing and other things that require ordered lists and decision tools!
I built a website (https://hpyhn.xyz) for hacker news users for reasons:
1. hn comments are valuable, I've spent a lot of time going through hn comments. I think there are valuable comments buried in the threads with fewer points, so it's not enough to just read top3 threads.
2. Sometimes a good post is ignored due to a bad title, sometimes I still have no idea what the post's theme even after I read a few paragraphs.
3. I want to filter out some posts I'm not interested in, but I realized I need read some other posts it's not a simple yes/no problem, so I gave every post a interesting score based on my own preference
so I built this tool to save my time while not missing out too much on hn
At least in principle, I'm still working on PAPER (https://github.com/zahlman/paper). (Or I should say "resumed"; I was having a rough time of it mentally in the summer through October or so and didn't really get any actual coding done.)
This has most recently involved a side diversion into a little tree-processing library (where file hierarchies are a special case) — Show HN within the next day or two, fingers crossed — and setting up a fork of https://github.com/pypa/packaging to support EOL Python (back to 3.6) and make some general simplifications (because even this is a fairly large wheel compared to the target project size).
Hoping I can kick myself back into the blogging habit again soon, too.
I'm currently improving this order queueing and sales recording web app for small coffee shops. Made primarily for my friend's coffee shop. Data is stored locally, and the app is fully functional when offline. There is an optional "syncing" feature to sync data with multiple devices which requires a sign up. This is a Progressive Web App built with Web Components. The syncing is made possible with PouchDB/CouchDB. Completely free to use.
Feels like I’m the only one here not already a greybeard, so just gonna share in case it resonates with anyone not already building awesome things: I’m working on learning how to program with C++. New at this, loving it, hoping to make a career change into IT in the coming year.
I’m building an open-source project to reduce GitHub Actions CI costs by running jobs on self-hosted runners on owned hardware.
The motivation is to fill the gap between local workflow execution by projects like https://github.com/nektos/act and self-hosted runner setups on the cloud.
My team’s requirements are simple and we don’t require all the features. We hope to keep ops simple and save costs. Any efficiency boost due to caching will be A bonus
Working on improving the data pipeline for https://iplocate.io - an IP intelligence service I've worked on since 2017. A couple of recent focuses:
1. VPN and proxy detection. We already track dozens of providers, but we can do better here. There's also a bunch of metadata we collect as part of this process which we don't currently surface, so I'm looking at what else we can bring to our databases and free API.
2. Better detail and evidence on how we build and test our own geolocation database, which we create from scratch. There's been a recent trend of misinformation about geo accuracy, including from some other providers, so I want to better explain the accuracy (and inaccuracy) of various techniques, our policy for when we prefer certain data, and so on.
(Open to partnerships for any folks looking for a new provider!)
Fringe physics: Trying to understand WTF the A field is in electrodynamics, and how I can measure it for a price I can afford. Specifically, I want to communicate through a wall of rock or sea water at VHF frequencies, with high bandwidth. I just upgraded my subscription with ChatGPT to try to grok all of the physics involved. It decided that since this could be used to covertly exfiltrate data, it wasn't something that could be discussed. ;(
Recently a friend acquired a Collins KW-1 transmitter, serial number 1. I helped him get it working again after a long period of disuse by it's previous owner. You wouldn't believe how often it turns out that wires and bolts don't actually conduct electricity.
Maybe I can help with one or two conceptual things. In classic E&M a field describes the potential (or force, if you prefer) a test charge would experience at that point. Note that the general case is impossible to visualize, as you're associating 6 numbers (3 for E 3 for B) with every point in space, so we normally think of simple setups and slice them up. Accelerated charges make waves in the field which are WAY more complex than people think. The way you model matter is dependent on the frequency of light. For visible light you normally think of it (especially metal) as a crystalline lattice of some characteristic length, electrons that can jump discrete energy levels, with molecules forming some sort of dipole that has more degrees-of-freedom (wobbling, twisting). I don't know about VHF, but the wavelengths are huge, like kms, and therefore way too low energy to cause electron shell jumps, so you'll probably model matter according to some very general characteristic like permittivity and conductivity. For seawater (which is a good conductor) subs use ELF, which is 100s of kms in air and can only communicate at bits/s. It's a fascinating topic, and very niche. Good luck!
Electrodynamics is taught to literally millions of people in Physics or engineering degrees across the world. It is the furtherest from fringe as it could be.
I would recommend following along the MIT OCW course or similar, doing the exercises. Use AI to help you follow the course and ask questions about things not clear to you.
- Building a micro-learning platform that uses AI-powered role plays and conversational assessments to gauge learner understanding instead of eg. a multiple choice questionnaire.
- I’ve just started designs and initial setup for a personal productivity system heavily inspired by the Newton & HyperCard and built in Rust. Idea is to use LLMs to build GraphRAG-like connections between content & break out of the standard app+document model. My current thinking is having ‘frames’ of content (notes, sketches, events etc) that are acted on by capabilities and displayed in views (timeline, calendar, stack, knowledge graph etc).
- Also working on a static site generator and CMS webapp that creates sites that can be viewed on anything, from web browser to TUI. Like if Gemini or Gopher also rendered to html.

It is a SaaS that allows you to create virtual characters to create, schedule and post educational or entertaining content on social media platforms with consistent personas. It is still very much work in progress, but already has some basic features working.
It allows anyone with ideas for engaging content to become a content creator without having to appear in front of the camera.
It can collide 96-bit truncated sha256 in under 24 hours on a 6700XT.
Next steps are a) figure out something interesting/useful to do with it (beyond surprising people), and b) modify it to support accepting contributions from untrusted clients (see "Future Ideas" in README). For a sufficiently interesting answer to a) I could create a "SETI@home"-like system.
A ~102-bit collision would cost $$ worth of rented GPU capacity, and 128-bit is optimistically possible with enough crowd-sourced compute (a ~5-figure dollar cost if you were renting).
An independent blogging and personal website builder. Source available (Ruby on Rails).
It’s not a novel idea but it’s gaining decent traction because it’s simple and (I think!) makes you want to write more. Which is basically why I built it.
Blog by email, custom domains, internal private analytics, theming and more!
Free forever plan, or only $29/yr for everything. Priced as I think personal/blogging sites should be. Everything is too expensive these days.
I've been working on an award flight search tool -- theres so many interesting problems to solve:
- How do you bypass bot detection?
- How do you achieve fast loading results?
- How are you able to teach users how to get the best deals possible w/ award travel.
Theres so much more to do in terms of reliability (bypassing bot detection) and onboarding new programs (right now, only American, jetBlue, Delta, Virgin Atlantic and Alaska are supported). But progress has been good and im excited about it.

Still working on Librario, a simple book metadata aggregation API written in Go. It fetches information about books from multiple sources, merges everything intelligently, and then saves it all to a PostgreSQL database for future lookups.
You can think of it as a data source, or a knowledgeable companion that can provide comprehensive book information for online booksellers, libraries, book-related startups, bookworms, and more.
I got a pre-alpha build running for those that want to test it out and the code is out on SourceHut[1].
Been really tough to find time to work on it because I have a baby that only sleeps in my lap, but I’m making progress very slowly.
I recently hired someone to rewrite the entire database layer, as that was written with the help of an LLM for the prototype, which should improve things too.
I am working on https://github.com/furkan/dockerlings, a TUI for learning docker (name and concept inspired by rustlings). It has attracted a surprising but welcome amount of interest, and I'm looking into extending it with more advanced exercise paths. Open to feedback & collaboration from all.
I keep on grinding on my Kubernetes IDE that allowed me to quit my day job over 3 years ago: https://aptakube.com/
I’ve also been playing with Bun and I have a business idea that would be a good fit, and huge potential but I just don’t have enough time to start something new anymore.
I’ve been playing with a Arduino compatible Uno R3 and a WS2812B RGB addressable LED light strip. I cut a 3m strip into 5 strips that are 28 LEDs long and soldered the lights together to make a display. I’ve been working on coding a font for the lights and can display about 10 different characters currently. It’s my first time really doing any sort of embedded work and my first time actually successfully soldering. Now that the thrill is gone since I solved this challenge I was thinking of making a remote control snow plow.
I'm building a Typeform/Google Forms alternative that integrates into existing applications and stores data in your own database. It allows you to define forms in JSON Schema or JSON Forms. Forms can be added or removed dynamically, and submissions are sent to your backend and in turn stored in your database.
Built using our full-stack library toolkit Fragno [0].
Enterprise software for SAP migrations. Thousands of companies need to move from ECC to S/4HANA before 2027, and master data quality is the #1 blocker. Built a Windows extraction tool + web app that cleans and transforms data automatically. What used to take consultants months of manual Excel work now happens in days.
I am working on way too many things to add here but one of them is https://www.familygpt.chat - ChatGPT for kids with parental control. I built it for my kids.
There's 100s of color palette generation tools, where most only let you customize a single color then try to autogenerate tints/shades without much thought about accessibility or tints/shades customization. The main features of this tool are:
- Emphasis on accessibility. A live UI mockup using your palette warns you if your tints/shades are lacking contrast when used in practice for headings, paragraphs, borders, and buttons, and teaches you the WCAG rules. Fixing contrast issues and exploring accessible color options is also made much easier using an HSLuv color picker, where only the lightness slider alters the contrast checks, and not the hue/saturation sliders (most tools use HSL, where hue/saturation changes counterintuitively alter contrast checks which makes accessibility really tough!).
- You can tweak the hue/saturation/lightness of every tint/shade. This is useful because autogenerated colors are never quite right, and customization is really important for branding work when you have to include specific tints/shades. The curve-based hue/saturation/lightness editing UI also makes this a really quick process.
- Instead of just a handful of colors, this tool lets you create a full palette. For example, if your primary color is blue, you always end up needing other colors like green for success, red for danger, and gray for text, then 11 tints/shades for all of these, so you want a tool that lets you tweak, check, compare and manage them all at once.
It's mostly a demo on mobile so check it on desktop. I'm still working on making it easier to use as it probably requires some design background to understand, but really open to feedback!
I shared this last month, and it seemed to resonate with people, so I'll share again and maybe new eyeballs will see it this time. I'm continuing to build a body of work on my retro productivity software blog, Stone Tools.
Previous articles which resonated with HN were on Deluxe Paint and VisiCalc. The latest post, "HyperCard on the Macintosh," seems to be making the HN rounds currently. Bret Victor himself chimed in on the HyperCard article over on Mastodon, filling in some nice historical footnotes.
https://posts.dynamic.land/@bret/115716576717006637
Unlike many (most?) other retrocomputing explorations, I specifically do not look at games nor do I tie myself to any particular machine, though I'm focused on the 1977 - 1995 period. I spend a minimum of two weeks with each productivity title, trying to learn it, building things with it, and generally trying to understand its approach to solving problems. I'd characterize my writing tone as casual, conversational, and decidedly light-hearted.
Each piece of software (so far, knock on wood) gets me thinking about some other aspect of related computing history, so I explore that as a tangent. With the Superbase article, I talked about "the paperless office." With the VisiCalc article I considered its impact on less obvious industries, notably hog farming.
I hope the passion and effort I put into the articles comes through. If you're interested in computing history beyond just the games I think you'll find something of interest on my blog. "This Week in Retro" did a segment about me and my various projects as well, if you're curious to get an overview of what I'm all about (link is queued up at the start of the segment)

It started out as a take-home assignment for a job I’m interviewing for (they asked for about 10% of what I ended up implementing but I wanted to do/show more :). It’s an aggregator for crypto exchange data.
The app reads the public data stream from exchanges, handles the nitty, gritty details of each exchange’s websocket connections, deals with its quirks, cleans up and normalizes the data into a uniform structure (currently only supporting spot trades) then exposes it downstream as an SSE stream.
Uses Go, Templ, and Mithril.js, and is open source
It uses LLMs to generate python code to scrap a webpage to fit any Pydantic model provided:

- Inspiree by my wife to pursue my weaponized desire to create things and organize my thoughts, I’m trying to gather my marbles to learn Swift/SwiftUI in order to try building an iOS app that which will automate directing and funneling data to where it needs to go.
- Updating my personal SSG to support Obsidian fully, which should simplify the publishing process a bit more. https://0xff.nu/hajime/
- Trying to find a new job, which is proving to be more difficult than it should be if you have certain standards about work/life balance.
- Writing an informative article about automating with/for ADHD which explains the motivation and solutions that I came up with for perhaps the weirdest, yet most annoying issues I face or forget about on a daily basis.
I'm building a session prep tool for tabletop RPG game masters. The idea is to make a narrative engine rather than another static wiki.
Most existing tools are great for storing lore, but they don't help you run the story. I wanted something that supports the "create now, refine later" workflow — get ideas into structure fast, then refine as you play.
Core features:
- interconnected world-building (NPCs, factions, locations) and story-building (situations, fronts, clocks)
- Bidirectional linking — connecting a story hook to an NPC makes that hook visible from the NPC's view
- Clock system with milestone consequences that can spawn or edit entities
- Situations fire different consequences based on outcome (players engaged vs. ignored the hook)
- Material waste detection — flags under-connected content so you know what's prepped but unused.
The main workflow is mindmap-based. Each entity gets its own context layer showing direct relationships. (Soon available in demo version)
Working on next: automatic player-facing content. As players complete situations, public notes from involved entities get published — so the GM doesn't have to maintain a separate campaign log.
I've been working on Mukbang 3D for the past year and a half—an iOS app that converts food videos into interactive 3D models using photogrammetry. Record a short video of food, and viewers can rotate/zoom/explore it while the video plays.
I recently added pose tracking of the 3d model so I can overlay 3d effects onto the underlying video.
Continuing work on my AI game development agent for Godot, Ziva[0]. Basically, big games are made in game engines, and game engines are hard.
Right now you can use it to chat about and modify basic things in your game; it automatically adds open scripts, scenes, and assets to your context, and uses around 50 MCP tools for editing. Currently working on refactoring the agent loop to use Claude Agent SDK so we can piggyback off the Claude Code developer experience and focus purely on the tool and integration side.
I'm looking at how to introduce unique, borrowed and GC'd reference types into the IR for my VM/runtime.
I'm inspired by the language Lobster's compiler that specialises functions to arguments of either reference type as a way of doing something analogous to using "escape analysis" to allow objects to be owned by the stack.
I think that perhaps specialised functions could be re-merged, with compile-time checks replaced with very cheap runtime checks taking advantage of "upper byte ignore" bits in pointers.
The VM will also need to support not just managed source languages, but also languages where unique and borrowed references are statically checked and possibly stored in objects.
Have been working on three micro-saas, all built in Elixir/Phoenix:
https://feedbun.com - a browser extension that decodes food labels and recipes on any website for healthy eating, with science-backed research summaries and recommendations.
https://rizz.farm - a lead gen tool for Reddit that focuses on helping instead of selling, to build long-lasting organic traffic.
https://persumi.com - a blogging platform that turns articles into audio, and to showcase your different interests or "personas".
Working on https://greatreads.dev/ A place to aggregate and find articles from developers' blogs. Right now, I'm building a submission form for people to submit new sources.
There is also a way to search for articles using vectors, it's called "Semantic Search". So basically you can ask, for example, "Postgresql and how to best optimize it." and it would search for articles touching that subject, or at least related to it.
Wondering about the best way I can add a weekly newsletter built on top of the content currently being ingested, and still looking for more sources to add to the database (let me know if you have any good recommendations).
This is very cool! I built something a little similar https://blognerd.app. I'm really interested in the RSS remixing idea, though I didn't quite crack it. I'll be interested to see how you get on
I’m building a web application to catalog your guitars and amps and pedals and record each time you service them and when you bought or sold them.
It’s a free service and I’m looking for BETA users to try it out. I switched up the tech stack and went with Rails with minimal AI assistance to go back to feeling like I did back in uni when I was building applications for fun and had to figure things out by trial and error. It’s been nice switching gears and doing things my way.
I have always wanted a super simple local startup job board for my country. No calls, no AI chat bots, no fancy matching. Spending 1-2 hours a week on this
I've started fund raising efforts for a project related to accelerating adoption of authenticated encryption between mail servers (it's time to move past opportunistic TLS).
I also launched a web browser extension last week, Blog Quest, which has some great early adoption numbers that exceeded my expectations. When I can find some spare time I'll start fixing up some of the early feedback/feature requests.
I'm building an application that can communicate with my Plex server, and also communicate with APIs like MusicBrainz and Spotify. From there I want to be able to track my Plex music rating history, and export playlists on Plex to Spotify for easier sharing with others.
There don't seem to be many automated tools out there that fit my need for this, so building out my own solution I have complete control over makes sense. It's a lot of fun to build this out exactly as I want to, rather than trying to configure a bunch of tools that I'm not familiar with and that don't meet my needs exactly.
The tooling I'm building up around this should hopefully make it easier for myself to get my playlists and track ratings off of Plex if I ever decide to abandon it for music listening.
I’m working on 2zuz, a product search engine that optimizes for the users rather than the advertizers.
The goal is simple: if you search for something specific, you shouldn’t have to scroll through ads, “inspired by your search”, or completely-irrelevant junk. You should just only see products that actually match exactly what you’re looking for.
Right now it searches across a few large stores and I’m iterating on the ranking and filtering. If you buy a lot of stuff online, I’d love feedback on where the results feel clearly better, and where they still fail compared to Amazon/etc.
I'm a product designer with no training in development. I've been hacking together a ridership data analysis platform for public transit planners using Claude Code. The data is all fake generated right now for King County Metro routes, but it pulls real GTFS for the route / stop information. AI coding is making things possible that I never dreamed of until recently - glad to be learning these tools.
There were many detours and scenic routes taken for what turned out to be a pretty straightforward repair in the end, but that’s not uncommon for these kind of things.
I’m on my way back from Home Depot to buy some screws that were missing (and a Xmas tree.) Soon all that’s left will be writing a blog post.
I'm working on an open source swift app that sends anything you circle in a pdf or epub to AI for an explanation. Currently it works with Gemini but I'm going to allow users to add their own OpenAI compatible endpoint soon.
I think it works best on Mac and iPad. Available on TestFlight and GitHub.
I'm making a web app that let's you create a QR code that you print and stick on your shop door or car windshield. When a stranger scans it, you'd get a notification on your telegram account or email without exposing your details. Kinda like a pager.
I’ve been knocking around and getting various false starts on three ideas for a while…
- a videogame. I've got a pretty killer idea in an open niche, but the indie market is so massively oversaturated that it feels impossible to get eyeballs.
- a next-generation post-RSS newsreader. But news is so depressing these days. I think most of the world wants to ostrich and I don't blame them.
- a reboot of Svpply, my own shuttered startup. I'd love to just make (another) thing that's about excellent clothes and shoes and artisanal pocketknives, but the way the economy is going, this feels grotesque. I was lucky to make it the first time when luxury goods were attainable _and_ normal people could pay for necessities; that window has closed.
There are too many LLM-related projects. Setting up multiple runtimes, Python, Node, Go, Rust and then some environments, different CUDA versions, dependencies is tedious. Managing updates later is even worse.
So, I'm building a toolkit that allows to keep things simple for the end user.
Run Ollama and Open WebUI configured to work together: `harbor up ollama webui`. Don't like Ollama? Then `harbor up llamacpp webui`. There are 17 backends, 14 frontends and 50+ different satellite projects, config profiles that can be imported from a URL, tunnels, and a helper desktop app.
I’m working on Paperboy (https://www.paper-boy.app/) a self-hostable service that generates a personalized daily research digest from recent arXiv papers (and optionally a few other sources).
It fetches new papers, scores them against a “research profile,” then produces concise summaries plus a short “why this matters” style rationale, and outputs an email/newsletter-like HTML digest. There’s also a small API for generating a digest, checking status, and previewing the render.
I built it because keyword alerts and generic newsletters were either too noisy or missed the stuff that was actually relevant to what I’m working on right now.
I'm working on https://www.numeromoney.com/pricing I don't even have the home page put together yet so marketing is still on the starting blocks! It's web app for helping to understand how you spend your money. I'm keeping it as simple as possible while trying to surface clear information about a persons spending. It came out of personal need (young families are expensive, it turns out!), and the existing products out there - YNAB etc were just too focused on budgeting. I just wanted to know where my money goes so I can focus on where I'm not spending it well.
My website is statically generated. The biggest problem I faced was adding comments to my blog, that didn't involve loading a ton of JS or third-party services, or add and maintain backend software (say php).
Do you think your dynamic content could be comments?
The live site has a blogging feature: Title, Text, Picture. Once I'll get to it, it'll be added to the demo site.
Comments is just the text aspect. So it's already working!
The question here though: in a low-trust environment, i.e. the public internet, what do you do with API key for your GitHub Actions/CI pipeline. Can they be narrow enough to be considered public? Can you get rid of the Cloudflare Workers?
I'm polishing up the second edition of "Hidden Markov Models and Dynamical Systems." The book explains several state space models and connects them to ideas about chaos. Here's a link to a pdf draft: https://www.fraserphysics.com/book.pdf and here's a link to source for the book: https://gitlab.com/fraserphysics/hmmds Once you install the source software, you can build a pdf for the book by typing "make book". I think that makes it reproducible research.
My goal is to help people get done with email faster, so that they can get back to doing other stuff. A lot of the features are designed around this goal: unified inbox, AI summarization, AI email drafting, etc.
Some of these are table stakes but I think there's also an opportunity to significantly revamp how email is done in the AI age. Imagine having your own personal assistant that goes through your email and surfaces the highest priority things that you need to know automatically.
I'm again toying around with the idea of building an ActivityPub Server built around the principles of RDF, JSON-LD and the Linked Data Platform. [0]
It can work already as a "Generic" ActivityPub server and it can be made to work with Client-to-Server API, but given that there are not mature clients for that, I am now in the middle of an exercise where I am taking the existing server and implementing Lemmy's and Mastodon's APIs based on top of it. Once I can get any Lemmy and a Mastodon client working, I will then start changing their own SDKs, and then I can replace calls from their application-specific APIs with direct calls to Linked Data server.
Started a newsletter [1] focused on agentic coding updates, nothing else. Other newsletters/blogs cover a lot of generic AI news, industry gossip, and marketing fluff. Having a focused feed is something I wanted for myself and finally I have enough time that I can write this newsletter regularly.
Web maps usually join together lots of small images called tiles (this is why you see square patches as google earth/map loads). They do this by querying a "tile server" API. It turns out this standard can also be leveraged to label and fine-tune models on map imagery. In my day job we built infra to efficiently serve imagery through tile servers for map visualization. So I wanted to test out ML applications of that infra.
I recently integrated Lazy Polars and running analytics in background processes so I can reliably provide a fast table viewing experience on dataframes that would normally exhaust memory of the jupyter kernel. Analytics are run column by column and results are written to cache, if a column fits into memory individually, summary stats for the entire dataframe can be computed.
Here's a demo video of scrolling through 19M rows, and running background summary stats.
A 90-min workshop to introduce development Teams the full potential of AI coding agents.
Over the last few months I’ve been optimizing an AI-first SDLC for real engineering (not vibe code), getting amazing results on small Teams both in terms of delivery output and devex.
Some friends asked me to formally present and help their Teams, and enjoyed every moment of it.
Creating an we autobattler game https://lfarroco.itch.io/mana-battle
It is being a good experience to learn how to work with shaders, and how well Electron apps run
As we pile more and more abstractions on top with AI, I have been on a really fulfilling quest fueled by curiosity to go more low level.
I've been doing a lot of assembly, C, WASM and plan to top it off with a look at GPU instructions and PTX. I haven't learned as much as in the last two months in years, it's been great. And surprisingly everything has turned out to be much simpler and easier to implement than expected once demystified.
Now to be fair, AI has sometimes given me pointers when I didn't fully understand something. Using Gemini 3 for free has been nice in that regard. However I consciously try to only implement code myself and to actually make sure I learned something that sticks.
https://lab.enverge.ai/b200-challenge/ - making high-end compute available to a few researchers, who are conscious about the impact of data centers on climate and local communities.
I’m working on Gluze (https://gluze.com) as a choose your own adventure story builder app. Trying to build stories where the reader gets to navigated and guide the journey.
It feels like somewhere in the last decade we've all lost control over our email inboxes. While it would certainly be possible to filter and sort it, I've been wondering if it makes sense to just start with a system that is designed to intake a bunch of streams of information. Then it could be pointed at the raw information e.g event calendars and news-letters as well as streams like Facebook groups/Instagram where I don't want to actually go to those apps.
Speaking at a meta-level, this seems like what we should really be using LLMs for right now: use-cases where user controls what is done on their behalf.
I'm working on Watermark'd. We want to give businesses a verified digital identity that works across the globe starting with businesses registered in South Asia (DUNS number that works for the 21st century).
What we do is quite simple
1. Verify the business is registered in the claimed jurisdiction.
2. Verify if individuals have the authority to act on behalf of that business.
3. Provide sharable credentials.
I'm building ourrhythm.de, a privacy first intimacy tracker spawned from a drunken thought: people buy those erotic advent calendars with 24 toys — do they actually keep up with all 24 rounds? It turned into a site idea.
I had some custom build scripts and sites for my dad and myself and was thinking I could make a simple SaaS out of it. Super early and didn’t advertise anywhere yet since the actual dashboard is very simple right now but it works and I keep adding the features I want to use myself.
I’m still exploring new forms of AI-powered learning tools.
The latest thing I’ve been working on is an adaptive mode inspired by the LECTOR paper [1]. Where each lesson is a single learning concept with a mastery score tight to it based on your understanding of the said concept, so in principle the system can reintroduce concepts you didn’t fully grasp later on, ideally making separate flashcards unnecessary.
It can be self-hosted if any one want's to give it a try!
This seems really nice, and looks like something I have been wanting to exist for some time. I will definitely play with it when I have some time.
I know this is a personal project and you maybe didn't want to make it public, but I think the README.md would be better suited with a section about the actual product. I clicked on it wanting to learn more, but with no time to test it for now.
Thanks for the feedback, I did update the README and included all the futures
and also there is https://talimio.com, I think it shows the future in a better way visually
I'm building a TypeScript to native code compiler, via the Dotnet CLR toolchain and Native AOT. This lets you use the excellent Dotnet std library - which in addition to being faster is also much safer than the npm ecosystem. There's also a node compat library, which exposes Node APIs but with CLR underneath.
The end result will be a binary (linux and mac for now) which you can run without NodeJS. Simple programs already work, and I have web apps very nearly running.
I’m working on Vocabuo (https://vocabuo.com/), a vocabulary-focused language learning app.
Two main differences between this and other Anki-like apps:
1) The words you learn are from YT videos, websites and ebooks you import in the app.
2) The flashcards are optimized specifically for learning vocabulary - cards automatically get audio, images, multiple sentence examples, words definitions etc. It can also create fully monolingual flashcards with just definitions or the words in dialogs.
My biggest flex is that I have users who have done more swipes than me (over 100,000).
This is something that started as a passion project - I wanted to see just how effective of a typing application I could make to help people improve typing speed quickly.
It’s very data driven and personalized. We analyze a lot of key weak points about a user’s typing and generate natural text (using LLMs) that target multiple key weak points at once.
Additionally we have a lot of typing modes.
- Code typing practice; we support 20+ programming languages
- daily typing test
- target practice; click on on any stat in the results and we generate natural text that uses a lot of that (bigrams, trigrams, words, fingers, etc).
I’ve tried it and really enjoyed how it works. I’d like to suggest a small UX improvement: for a typing app, it would be much easier to avoid using the mouse. When a practice ends, the user should be able to press the RETURN key to move to the next practice. (instead of clicking the Continue button)
I'm working on my writing, of course. In the latest episode of my life, my mother surprised me with fresh news about the origin of my name: https://rikverse2020.rikweb.org.uk/poem/names
I'm working on a graph representation of complex data flows through a large organisation. The graph looks like crap, partially because hierarchical dagee graph layout algorithms apply a naive way of removing cycles that ruins the shape of the graph.
I've figured out a better way to remove cycles that preserves the shape of the graph in a way that works well for our purpose. Now I just need to figure out how to minimise edge crossings and line up nodes in such a way that it's more immediately obvious how the data flows between different systems.
I'm working on something called Kopi: a CLI tool that replaces the slow process of restoring massive production database backups on a dev machine with a "surgical slicing" approach, spinning up lightweight, referentially intact Docker containers in seconds: It spins up the exact schema of your source db and generates safe, synthetic datasets in seconds. It can, if you want, also replicate the actual data in the source DB but with automatically anonymized PII data.
It can replicate a DB in as little as 9 seconds.
It's Open Core: Community Edition and Pro/Enterprise editions.
I'm working on hand-building mugs. Throwing clay around in a studio, etc.
But I'm also thinking about it as a product manager based on my tech experience. Looking at what people like in mugs, creating templates to exactly size the mugs to people's preferences, creating re-usable molds to put repeatable components together, and taking detailed notes on exactly what I am doing in-studio to create a repeatable, reliable process to create a product that will sell.
It is going poorly so far, but each iteration gets better, so hopefully I have everything down before I end up with 100+ unsellable mugs in my kitchen.
For a long time I've been looking to solve the repetitive schema pattern issues in SQL. This week I created a DSL that allows parametric polymorphism for SQL, and I wrote a compiler for it.
A open source Node.js lib that allows people to create and version control resumes using YAML.
Support LaTeX/PDF/Markdown outputs in one shot with professional typesetting.
Support English/Chinese/Norwegian/French languages out of the box.
With clang style, real time error reporting.
I’m working on a way to personalize the content of your website to any visitor - with minimal setup (it’s just a script tag). We’ve just launched so if anyone wants to try it and reach out my email is in my profile!
A portable, robust desk cloud chamber with a 10x10cm viewing plate. It's taking ages and having just one AIO cooler wasn't the smartest choice, but nothing else would've fit. It's a way harder project than I expected, at least if you want everything to be vibration-resistant for car transportation and for it to last years. I've learned a ton.
On a dedicated language analysis model. For starters, it will detect a text language in microseconds. For comparison, a popular LLM takes 100 ms (10 tokens per second) on a full GPU to analyze one token; this new project processes a token in ~100 ns on only one CPU core!
HALUD YOUR HORSES is a small containerized development workflow designed to reduce exposure to supply-chain attacks in the JavaScript and Node.js ecosystem. Every project runs inside an isolated container with its own node_modules volume. Nothing from npm executes directly on the host machine. The tools are simple shell scripts that create, enter, and fork project-specific development images.
Also working on getting Nix setup on my devices, including a PR for the official installer to support OpenRC + BusyBox distros. Hopefully will get merged soon :)
Still WithAudio https://desktop.with.audio . It's getting some attention and has actually sold licences!
Someone asked for a free license in exchange of detailed private review and bug reports. They have reported more than 10 bugs so far. I'm working on some of them right now.
WithAudio is a one time payment text to speech reader app. It's one time payment because it has no server and no recurring cost! A nice side effect of this is it's 100% private.
The fastest knowledge base for software teams, Outcrop.
A lot of teams enjoy using Linear for product management but still have to use Notion and Confluence for knowledge management. I’ve built Outcrop from the ground up to be fast with much more reliable search and realtime collaboration.
Hundreds of teams from startups and major companies have signed up for early access and many have made early commitments to support the development of Outcrop.
If your team would be interested, I’d like to hear from you!
I'm working on a collection of mnemonic images for learning written Chinese. Each has a solarpunk-style image referencing both the character's meaning and pictographic etymology, with the character overlaid and color-coded to indicate the tonality in Mandarin.
While I'm talking about it, do the folks here have any suggestions where I should make it available? I want it to be a free educational resource for whoever might want it.
For a fun project; rejuvenating a 1978 Chess Engine https://github.com/billforsternz/zargon. It's the second time I've worked on the same engine. The first time I got it working nicely on modern machines, running four orders of magnitude faster than in in 1978. This time I hope to get it running much faster than that. I found a bug in the 1978 Z80 assembly the other day. A blog post "Fixing a 50 year old bug..." or similar suggests itself.
I have been slowly progressing on writing a Rust like language that compiles to JavaScript for a few years now. With the rise of AI and it becoming better recently with Opus 4.5, specially with Rust, I've been trying to have a speedrun version of it.
Think of it as TypeScript but with full algebraic types and other commodities from Rust:
Open Source ERP system for Makerspaces and Community shared system.
Started out as a kanban style of system where anyone could request that we re-order cleaning supplies at a Makerspace. Has evolved to tagging assets and maintaining those assets and I'm working on adding ESP32 based device control to enable/disable devices through those QR codes.
I'm building a platform for people in my rare fruit meetup group exchange scions. I've never built a react native app, but with the help of Claude it seems possible to build for the web and iOS/Android apps with minimal experience. Hoping to make it really useful for our group before sharing it with others.
I've been working on LLMParty for some months. It is a collection of experiments that use LLM under the hood. For each experiment I tried to play with something different, such interaction, LLM knowledge, use, etc
Building a modern cross platform PostgreSQL DBA tool (and network service), with all the features I wish other tools had, with the hopes to extend it with features for small-medium teams - hyper focused on good DX/UX.
I had just launched Zunorm, an AI CSV editor where you can plug in any model from OpenRouter, or connect a locally running Ollama model. Check it out for free - https://zunorm.com
Slowly degoogling my life. Switched to FastMail a while ago, it works. Have written a simple shopping and todo list web app, and a minimal photo gallery. All very simple, mostly for one user only: Myself. Using these as excuses to learn about coding with LLMs. As I have retired a few years ago, I can afford the time, and work with no stress or deadlines. Also slowly improving my beer tracker system. All this as perl-based cgis under Apache, running on my home server/workstation.
Working on building an investment assistant backed by real time data. ChatGPT and Perplexity finance are amazing, but all of them are based on web search data only, which is a big limitation in finance since realtime data is important.
We have an agent that has access to almost every data point you can think of in the stock market (as much as we can get), which gets leveraged before answering.
And we also figured out ways to build amazing charts in between answer snippets, which looks very cool. Investors are usually very visual.
Last week I spun up a HN clone for digital nomad news.
Since I was researching DNS and global mobility, and wanted to share links with others, figured I'd just spin up a link site (though I'm still the only user).
One unique difference is I have a field for English Title, since I consume a lot of Korean & Japanese articles and want to share these, but don't want to have people translate the titles before they understand why they should read them.
Refresh Agent is an AI Agent for SEO and Marketing Analysis.
If you've ever tried to use Google Analytics (GA4) and Google Search Console (GSC) to figure out what's working with your marketing, and what to do next to grow, you have probably got frustrated at some point.
It acts as a Marketing Strategist. You can ask questions like "why is my SEO traffic down this week" and it will give you a clear answer based on your site's performance data, as well as a checklist to improve.
When someone dies, you don't get even one extra second to access the documents and information they meant to share it with you.
Trying to fix this problem with Eternal Vault.
Could you go into some detail regarding your approach to security? Presumably, due to the sensitive nature of the documents users will upload, you have a number of safeguards in place?
- Files are end to end encrypted with a master key generated by you on your device during onboarding
- How do your family access the documents when only you have the key and it's E2EE? The idea is the key is splitted via Shamir Secret Sharing when you add a trusted contact, once the doomsday is triggered and they recieve the notification, only then they can use their "shares" to reconstruct the master key and open your vault and access the documents
It's a full identity and authorization platform targeted for service-to-service use cases. But my focus the last couple months has been to make provisioning identity super easy, and I think I've done that (at least compared to something like SPIRE).
So if anybody has CI/CD pipelines, AI agents, edge-functions, or multi-cloud workloads they want to give auditable identity, I can help!
building out a simpler way for users to report bugs and provide developers with a context-rich environment (console/network logs) that makes fixing bugs easier.
eagerly looking for beta testers, join our waitlist
With the recent work done enabling the use of Common Lisp in the browser on WASM, I've been thinking about spinning up a really simple static site that's just a CL REPL for people to play with.
I'm working on a multi platform client for ATProto servers, like Bluesky. The emphasis is on a clean orthogonal UI, running on platforms the default client doesn't run on, and better use of screen space on small devices.
It's a work in progress, but it's at a stage where if you ask nicely I'll let you know where to download it.
There are a lot of apps that can be built on ATProto, the PDS, etc. If you are exploring the same space I'd especially like to hear from you. I'm easy to find, which is the most useful thing about being named Zigurd.
This weekend I'm working on a new song for my NES game, Tactus. I've been busy setting up the business and preparing for its first outing at a convention, so it was nice to relax and just create for a bit.
i built a small tool that looks at who is starring a github repo by analyzing public data.
it gives aggregate views like role and seniority breakdown, top languages and frameworks, companies represented, where stargazers are located, and an aggregate feed of blog posts from people who starred the repo.
I'm about to launch a new (now free) version of my Mac app, CurrentKey, which helps you keep track of workflows across macOS Spaces and track how you use your Mac. https://www.currentkey.com It had been a subscription app (4.5 stars) pulling in a few thousand per year, but I recently decided to try to broaden its appeal and make it free. The new version will launch within a day or two (the launch build is just "Waiting for Review" in App Store connect).
Store your graphs in Parquet files on object storage or DuckDB files and query them using strongly typed Cypher. Advanced factorized join algorithms (details in a VLDB 2023 paper when it was called Kuzu).
Looking to serve externalized knowledge with small language models using this infra. Watch Andrej Karpathy's Cognitive Core podcasts more details.
Lite³: a binary format encoding JSON documents as a serialized B-tree, making it possible to construct iterators on them directly and query internal fields at indexed speeds. It is still a serialized document (possible to send over a network), though now you don't need to do any parsing, since the document itself is already indexed.
When overwriting fixed-sized values like integers or floats, the old value can simply be overwritten. Holes are only left if the overriding values do not fit in the old location (strings, byte arrays).
To clean up unused space, you start an iterator at the root of the document and recursively write to a new buffer. This will clean up all the unused space. This operation can be delayed by the application for as long as they wish, until the size trade-off outweighs the cost of rebuilding.
I built a PWA that feeds you random, high-engagement Wikipedia topics (like the Great Emu War or the Demon Core) in a swipeable deck. Swipe right to save, swipe up to read "trivia snacks" instead of the full article. The idea was to have an antidote to doom scrolling.
The project started at a "vibe-coding-hackathon" and is now starting to become my main side project.
I’m hacking on different side projects but currently I’m working on developing a platform for helping freelancers or small agencies understand aws costs and optimize their environments
Its been a pain point for a lot of the clients I work with helping them understand and optimize their aws costs
They might get a surprise 1000 dollar bill and won’t be able to understand why it happened or what incurred that costs
Currently working on a code formatter and parser for Supercollider's sclang.
Supercollider is an amazing language, but the development tooling is severely lacking - we need good tooling, and now with LLMs in play and my coding ability leveled up from doing GATech's OMSCS, I'm finally able to tackle this.
I'm learning rust while I'm doing this too, so it's been an experience. Fun, though.
Imagine direct p2p payments that can be performed without reception.
I got thinking about what the equivalent of digital cash would
be in 2021 and have worked on it on-and-off ever since. It has an optional NFC component.
Technically what I have is good enough to ship, but I’ve been unsure of the legal footing of such a project so it’s been on ice for a while now.
https://tagbase.io … our mission is to stop counterfeits and empower brands.
And as the CTO I have the privilege to play with all the nice technologies: Elixir both on the web and Raspberry Pis via the https://nerves-project.org.
Having an IT background I love the challenges that come with hardware design and to learn new stuff because of that.
Nope, as we configure the tags. For now we support to industry standard chips from NXP, but this will expand in the future to other manufacturers as well.
A purely functional and asynchronous effect system for F# which started as my thesis in university.
It's inspired by ZIO and Cats Effect for Scala and has its own fiber system for scheduling functional effects.
I don't have much time to work on it now a days, but I try to keep up it as much as I can.
I also don't have ambitions about getting a lot of users (if any), but I really enjoy working on it :)
I'm working on a way to make it super easy to create and share beautiful photo galleries that tell a story. Take your folders with photos and create a web gallery that works great on all devices.
The project has a CLI interface that is free and open-source, but you have to self-host the gallery. We are also building a SaaS app which is basically a managed version of the open-source tool with a visual builder and we take care of the hosting and CDN.
Overly specific LLM research into KV cache eviction.
The vast majority of tokens in a sequence will be irrelevant to an attention mechanism outside of a very small window.
Right now however we tend to either keep all cache values forever, or dump them all once they hit a certain age.
My theory is that you can train model to look at the key vectors and from that information alone work out how long to keep a the token in the cache for. Results so far look promising and it’s easy to add after the fact without retraining the core model itself.
A database desktop client, built with Tauri & SvelteKit.
"But there are many already!" I hear the crowd exclaim.
I respond, "Yes, but..."
It's really something I want for myself. Lightweight, as fast as humanly possible, extensible via plugins (in fact the entire app is mostly plugins, with a small core to glue it together), and a tiny bit of LLM (call it AI if you wish) integration to ask questions about the database or generate/review queries.
I'm working Solarite, a library for doing minimal DOM updates on web components when the data changes. And other nice features like nested styles and passing constructor arguments to sub-components via attributes.
Skyrim mod manager for the Nintendo Switch version of the game.
It’s mainly for personal use because converting, renaming, and packing mods in bulk can be very tedious. Especially if you're always changing your mod list (which is a given).
However, once I make it more user-friendly and add a proper GUI, I’ll likely release it to the public.
Been working on https://qave.chat, Wanted Slack to be more supportive for developers so been iterating on feature parity with Slack but optimised for developer workflows.
This looks like keyboard driven commands, secrets store (to be done) and scripts that you can write and store without spinning up a new server (easier chat ops)
Still in early alpha so after a few more polish it'll be ready, but you can try it right now!
Next step is to integrate a visual data pipeline by using ImNodes. I‘m slowly making progress in my experiments, but C++ has a steep learning curve, especially when targeting MacOS and Windows at the same time.
I am building a free poker training web app, specifically aimed my friend JG who wants to place sufficiently high enough in a WSOP or WPT satellite tournament to qualify for the main tournaments: https://holdempuzzles.com/
Reimplementing something I originally did in python in rust. Both vibecoded - want to get a better sense of how they compare and whether there is upside to be had from rust typing and „if it compiles it’s probably ok“
Thus far - uses way more tokens and noticing reduced steerability. The linting & fix loop seems much smoother though.
I've been working on a no-code multiplayer game editor. The idea is to let anyone create multiplayer games in a few clicks without writing code—and share them instantly.
The platform handles all what's necessary (and annoying to setup) out of the box: multiplayer, controls, mobile/responsive/ inventories, save/load, leaderboards, quests, dialogue, etc... Users just select what they want and configure it with clicks.
Technically, the engine just reads a config file and renders it for players. I've built all the foundation blocks that interpret the config.
I'll soon be onboarding game designers to stress-test the editor/engine. Still polishing templates so people have a good starting point, but it's functional and I'd love feedback!
Im building a calendar for my car navigation system https://e39.dev
Last winter I built a Matrix client for it. This time around I want to wrap Akonadi with a DBus shim and consume that model in custom calendar widgets and UX I’m making for a rotary knob ui.
I want to run the same app on an intel atom tablet on the side of my fridge, with a Griffin PowerMate hooked up to it for input.
a trio of short motion pictures that i've written, directed, produced, shot and edited, and will launch on my website late next month, followed by a european tour of free screenings with my pop-up, makeshift cinema. an experiment to see if i can become fully-funded by tips/donations from the audience.
sign up for the mailing list in footer of my site if that sounds of interest:
Working on updating my Your-Age-in-Days app[1] for iOS 26. The main motivation was to have the days I've lived always available on the lock screen with a more native feel than the workaround I had before (nightly Shortcut which updates the background image and adds the current number as an overlay to it).
I'm trying to make localhosting (https://thelocalhostinger.dev/localhosting) a thing. It's about finding ways to strip away unnecessary complexity of selfhosting in very specific edge use cases.
I've been on a break from coding for about a month but was last working on a new kind of "uncertainty reducing" hierarchical agent management system. I have a writeup of the project here: https://symbolflux.com/working-group-foundations.html
Creating Daino Qt - a collection of components that makes Qt apps feel and look native on both Desktops and mobiles (each with its own set of challenges).
Developing Qt apps with C++ and QML is a blast - the fast performance of C++ and ease of use of writing UI in QML. But there is so much left to be desired with the built-in Qt Quick components - mobile issues like non native text handling, non native swipe-able stack view and much more. I’m aiming to bridge that gap.
It's still native (in terms of performance and ability to customize the look and feel) and working pretty well, it's just that not enough effort was put into making the built-in components behave and look like those on the platforms it runs.
Started working on a training plan builder after getting frustrated with trying to use an existing service (trainingpeaks) and not finding the controls intuitive enough without being a coach in their system.
I wanted something local and offline first + 10-20% better than excel, think I'm missing a few features other might find useful, but it works for my needs which has been great.
tinygrad’s small set of operations and laziness made it easy to implement. Tho my overall sense is that neural network verification is currently more of a research interest than something practical.
I know 4 languages. 3 of those I learnt because of my family. I learnt Russian because of work (+fun). I feel that it is always best to go the classic route and learn a language from a manual (currently learning mandarin from a manual) and that gamified experiences of learning languages have a very low learning/effort ratio.
When I'm not working on college applications, I'm working on my HS senior capstone project: Porting the Bridge Designer[0] to the web. So far we've got bridges rendered statically and the load simulation working in code (no load visualisations yet). I intend to post it here when it's ready.
A few weeks ago I built a very simple metrics tracker that I had been looking for myself... a middle ground between complex observability platforms and tracking a number yourself and then finding a way to visualise its change over time.
I had had the idea and the domain registered for years and recently just took the leap to put it out there.
PostgreSQL extension providing big speedups on COUNT/SUM/DISTINCT and GROUP BY for the most common data types.
I'm looking for people who have pain around slow analytics, avoiding migration from PostgreSQL, delaying pg upgrades or other big reasons to adopt something like this.
Place discovery companion that de-noises your environment. Repeatable, one-stop-shop for information, personalized. Quick to decision. Updates live (best on mobile).

We are passionate travelers with 30k km under our wheels and we want consistent information across places we find ourselves at. Now are trying to figure out how to help others.
It helps to comprehend research papers (and not only papers - any document on any language) faster.
The tool is free to use, because we have credits from GCP. I guess at some point we'll need to introduce some level of subscription fee to keep it alive and useful, as it uses LLMs and vector search quite a bit.
Building a little extra tool for my reservation system, which simulates guests reserving accommodations before a customer launches. This is nice if you have no idea how users will respond to your availability and options.
We have an ML model that's trained on real reservations and use an LLM to decide why a user mightve opted out. We apply personas to this LLM to get a bit of a sense how they would probably be operating the booking flow.
This is what my company does (https://espresso.ai/), I'm taking advantage of the end of year quiet time to hack on some more R&D-style projects we have.
I’ve been working on "Next Arc Research" — https://nextarcresearch.com - a wrapper around my curiosity to understand how AI, compute, and capital might change markets by 2030.
It’s not a trading tool or product. More like a weekly, machine-assisted research project. Each cycle I run analyses on 120+ public companies across semiconductors, cloud, biotech, energy, robotics, quantum and crypto. The framing is inspired by Emad Mostaque’s “The Last Economy” thesis — the idea that when intelligence becomes cheap, the physics of value creation start to look very different. I originally built it for myself and retail investors in my family but I figure it could have more general utility so prettied it up a bit.
The system uses large-model reasoning (GPT-5+ though I've also tested Sonnet, Gemini and Grok) combined with structured scoring across technology maturity, risk, competitive positioning, and alignment to AI-era dynamics. The output is static HTML dashboards, PDFs, and CSVs that track month-over-month shifts. I'm adding to it weekly.
Mostly I’m trying to answer questions like:
* Which companies are structurally positioned for outsized upside in The Last Economy?
* How should I deliver the research so that it would have been actionable to someone like me 30 years ago?
* What signals would help folks identify “the next NVIDIA” 5 years earlier?
The inference costs real $$$ so I've set up a Patreon that, hopefully, will allow me to scale coverage and extend the modelling and methodology. There is a free tier and some recent, complete example output on the web site. I'm also happy to gift a free month for folks willing to provide constructive feedback: https://www.patreon.com/NextArcResearch/redeem/CC2A2 - in particular I'm looking for feedback on how to make the research more actionable without drifting into "financial advice".
I don't collect any data but Patreon does for authentication and Cloudflare does to deliver Pages. The Last Economy is here: https://ii.inc/web/the-last-economy
Computing entropies of high-dimensional random vectors for a theoretical neuroscience study. The journey is mostly a repetition of (1) almost giving up because it's completely hopeless, (2) taking a hot shower, (3) realizing there might actually be a path forward, (4) almost giving up because it's completely hopeless.
Legal-tech: Using AI to help attorneys bill flat-rate instead of hourly. It's data intensive, but possible if you go through their old time entries and tell them the flat-rate price of all of their hourly work. 93% of attorneys bill hourly, primarily b/c they don't have any sense of the cost of the upcoming work. DM me if you want to work on these problems.

Play with friends or against robots. Couldn’t find a single deck version online like I used to play growing up.
Good resume project. Would love to know your thoughts about the UI!
A tool for K8S operators that replaces brittle imperative reconciliation code with type-safe state machines generated from declarative YAML definitions.
It also bundles error handling / logging / metrics / traces for state transitions.
Not sure if I'm missing a better tool but trying to keep a good working mental model of this has been a nightmare for the operators I've maintained.
Working on a single-node job scheduler for Linux. Large HPC clusters use schedulers like SLURM or PBS to manage allocation of resources to users, but these systems are quite overkill when all you have is a single node shared by a few users.
I am trying to offload as much of the complex stuff to existing parts of the kernel, like using systemd/cgroups for resource limiting and UNIX sockets for authentication.
An RSS aggregator app.
Open source, self-hostable, and I'm running a free hosted instance at the moment. This is the first time I have ever gotten to the stage of having live users in a prod environment for my own apps. Pretty cool stuff.
Ever since I tried grok imagine I became obsessed with the idea of re-imagining classical paintings or animating them so I created https://ravaan.art
I don't necessarily have a vision for it, so if you think it is cool tell me what you think could be added to it.
Yes, awesome mate, fascinating. I just checked the tech stack and found you are using Next.js. very minor issue. The OG Meta tag pointing to your localhost url, please fix it :-)
Thanks for the heads up! I had taken it further locally with a landing page and a blog section (empty for now) but didn't finish up the deploying it. I will patch this one.
Home, on going work to get local Kubernetes dev env running as close to a production one as possible - ingress, external-dns, ACME CA, load balancer, Argo, registry, prom-operator etc., running entirely locally. Work, similar but in Docker Desktop on Windows and Mac.
Longer term personal aim is a self-hosting platform based on k8s with straight forward bootstrap, similar to Yunohost but k8s based.
On a mission to build the best interviewer platform with emotional intelligence, to make the conversation comfortable and engaging for the user.
Not just a chatbot, but a deep real-time knowledge capture framework with conversational AI.
Our first consumer product is Argo https://getargoai.com, but we're working on a B2B version as well.
We dug deep into what makes a conversation not just a nice chat but a deep, profound, top-notch interview, when the interviewer who neither pries nor forgets.
What makes people come to Joe Rogan or Lex Fridman and talk for 4 hours straight without feeling interrogated or experiencing conversation fatigue?
What if we had an app on our phone that helped us capture a story, filling the gap between two photos?
These are the questions we're excited about. Would love to hear what everyone thinks about conversational AI beyond the typical assistant paradigm.
Working on an iOS/Android app that lets gamers of all flavors connect with each other.
The main selling point of this app is that I do everything to let you continue do what you're doing while the algorithm search for other players. You receive a notification when a group is found or when a player is found.
Its not out yet ! The beta will be released in less than two weeks !
We have a website https://jynx.app/
If you want to leave feedback there is a form for that
Local asr/stt on mlx for apple silicon based on Facebook omnilingual model that was just released. Used Claude to port model weights from PyTorch to mlx (that was exciting, claude can do that).
Personal productivity app. Mirrors contents of a file (TODO list and other info) on your phone. You can make a call with Grok to brainstorm specifics. The goal was to remove any friction possible, to make focus easier.

Fun/Passion-Project: A small advent calendar featuring (weird) Acro-Yoga flows we collected throughout 2025. (Acro-Yoga is a partner sport combining acrobatics and therapeutics, you should try it, it's a really great sport!)
Hi, all! Please check out the Freetracer RC build! It is a FOSS, native, privacy-focused ISO/BIN/other common bootable image formats flasher to removable media, written in Zig!
I’m working on an open-source thing that lets you co-draw diagrams with an LLM inside draw.io/diagrams.net.
You can ask the model to rough out an AWS/GCP/Azure architecture, but the key part is the loop: you still have the normal editor, so you drag boxes, rename stuff, add your own bits, and then say things like “clean this up”, “split this service out”, “add a read replica here”. The AI edits the real draw.io XML, it’s not just generating a picture, so you and the model are basically sharing the same canvas.
It can also try to rebuild a diagram from a screenshot/PDF and then you keep iterating together in chat + manual edits.
Recently I added “bring your own API key” for a bunch of providers and support for uploading PDFs/text to turn existing docs into diagrams.
Pretty simple, really. Cloud native app that scrapes job postings for higher ed institutions, then send me a daily summary based on a handful of keywords. Mostly targeting something to find remote jobs offered through schools. I like working in Higher Ed and my wife is looking for a remote job. Seems like it should be easy to vibe code and run in a free tier.
I’m (possibly) over-engineering a new personal site using SvelteKit. It’s a blog + public project tracker. All the site content is created and edited using Obsidian, and there’s a build script that parses all the markdown in the vault when the site is built. I’m planning on working on several new projects next year and wanted a place to document them
mw-injector[0], it's a WIP project. It detects what Java, Node, Python or Golang services are running on a host and instruments it with Opentelemetry APM. Inspired by Otel-injector[1] but it automatically selects service names for each service so you have service level segregation.
Vive Coding an AI App that searches the net for different types of financial assets and uses the data found to Predict the Future of Financial Markets, i.e. price projections. Just for fun, though the results are very accurate :)
It's not ready for prime-time yet, so not open-source at the moment. I've managed to have it search over 9 asset types, including Crypto, stocks (e.g. different categories), but it is slow going as I am using a free-teer AI. It's found some stuff on the net that is barely in the pre-sale phase, and it predicts 10,000% gain but don't know if it is an accurate prediction or a massive hallucination. Also, I know this has the potential to be a money maker, but I don't have neither the experience nor the financial resources to host this online or make this a viable money-maker at the moment, unfortunately :(
>>Have you tried handing it over some test money on a trading platform to see the results?
Not everybody has test money to play with. I'm in that group due to the crap economy left behind by previous politicians.
>> What prediction algorithm is it using?
As money is an issue, all I have at the moment is Google's AI Studio which is definitely not opensource, in my view. Though it is more forgiving than other vibe tools out there with their usage quotas. The market predictor has no capabilities to connect to any proprietary APIs as that requires money. That being said, it should be possible to modify the code so that it uses proprietary APIs should anyone want to do it. For now, I'm just adding stuff to it via VibeCoding that I think could be helpful. The main goal is to turn it into a research App that finds potential assets that will double to triple in the near feature or stocks that are prime for shorting, etc. I am also thinking of adding investment simulation capabilities but not quite sure how to go about at the moment. Turning some of its capabilities as a learning platform could be a good way to monetize the app. Not really a serious app at this moment, though, as I lack lots of tools to accomplish this.
Based on the code provided in services/geminiService.ts, here is the breakdown of the algorithms and sources used by the market prediction AI application:
Prediction Algorithm:
The application does not use traditional quantitative statistical models (like ARIMA, LSTM, or Linear Regression) running on raw numerical data. Instead, it uses a Generative AI / Large Language Model (LLM) approach:
Model:
The app utilizes Google's Gemini 2.5 Flash (gemini-2.5-flash).
Methodology:
Context Gathering: The AI first performs a real-time Google Search (tools: [{ googleSearch: {} }]) to gather the latest text-based data, news, sentiment, and technical analysis summaries available on the web.
Semantic Analysis:
The AI acts as a "Senior Financial Analyst" to interpret this unstructured data. It synthesizes a sentiment score (0-100) and predicts future price targets based on the qualitative data found (news catalysts, earnings, etc.).
Chart Generation:
--The historical and forecast charts are generated mathematically within the code using Deterministic Linear Interpolation.
--It connects the current price to the AI's predicted future price targets (1 week, 1 month, etc.).
--It adds algorithmic "noise" (randomness seeded by the asset name and date) to simulate market volatility visually, ensuring the chart looks realistic but stable for the specific day.
Data Sources:
--The application relies entirely on Google Search Grounding. It does not connect to specific hardcoded financial APIs (like Bloomberg or Yahoo Finance API directly). Instead, it instructs the AI to search the public web for specific types of information.
Based on the prompts defined in the code, here are the sources and data points the app targets:
Real-Time Aggregators & Search Engine Results:
--Live Google Search results for real-time price estimates.
--Global financial news outlets (indexed by Google).
--Market sentiment analysis from web summaries.
Regulatory & Official Documents:
--SEC EDGAR Database: Specifically targeted in prompts for Stocks, Quantum, and Cannabis strategies to find filings.
Company Press Releases:
--Used to identify fresh catalysts like contracts or product launches.
Technical Data:
--Support and Resistance levels (retrieved from technical analysis articles found via search).
--Relative Volume (RVOL) and Intraday Volatility data (for Day Trading strategy).
--Chart patterns (Bull Flags, Pennants, Opening Range Breakouts).
Sector-Specific Sources:
--Crypto Launchpads:
Seedify, DAO Maker, Polkastarter (specifically for the "AI Presale" strategy).
Venture Capital Reports:
--Data on VC investments and insider buying.
Industry News:
Specific searches for Quantum Computing breakthroughs, Cannabis legalization news, and AI technology updates.
Market Dynamics:
--Short interest data and borrow fees (for the "Short" strategy).
--Analyst upgrades/downgrades and price targets.
Macro-economic trend reports.
As I mentioned earlier, it actually found lots of legit assets with breakout potential but also finds crypto asset for that I suspect are scams but have a presence on the web.
Hope that provides a bit of context to your query.
I'm trying to solve the brachistochrone problem by numerical optimization. I started with the minimal surface problem to get a foot in the door: I discretize the integral as a sum of constributions that depend on the function values at specific points, then use autograd libraries for optimizing a non-linear scalar loss function
Working on a blog post about default behaviour in ONNX Runtime when using the CoreML execution provider. Basically the default args lead to your model being ran in FP16 not FP32.
My twins (in high school) and I are building an AI study buddy.The idea is simple. A peer-level “study friend” you can work alongside, ask questions, and stay on track with.
It’s not doing anything ChatGPT or Claude couldn’t do. The goal is packaging it into something that feels a high-schooler would actually want to use when they’re studying.
We are also using this as a weekly project to learn the abstract stuff. Product thinking, design, pricing, marketing, and how to turn a vague idea into something real. Each week the kids prioritize a feature, research it, write up the idea, and then we build (or cut) it together.
Our stack is Claude Code, TypeScript, React and it's hosted on Cloudflare Pages for frontend + Workers for API.
No login or credit card required to try this out. We welcome your feedback.
At work I'm implementing new 3D map geometry stuff for my employer (Mapbox) and as a a sideproject I'm building a simple 3D modeling software that gets you from idea to reliable, solid parts fast (https://www.adashape.com/).
A bookmarks assistant. A simple place to save all your links, find them with chat. The app automatically adds summaries to all links and send you an update of what you saved every Sunday morning. More features coming.
I’m very been trying to get into hardware more. This years project was a speaker which is nearly done (with a few weeks to spare).
Next years (and probably a couple years after) is an electro-mechanical smart watch. Sourced some Ronda GB22 gearbox motors and tritium tubes and planning on using a pcb for the face. What could go wrong.
II’m currently working on Focusflows.eu, a tool I’m building to help people improve their focus while working or studying. At the same time, I’m exploring new ideas around productivity and digital well-being, and experimenting with features that make it easier to stay focused without feeling overwhelmed.
I've been working on a LLM fiction writing workflow and associated tools. It's built on agentic coding tools with lots of structure, guidance, prompting, and critique. Almost all of the flow is on the filesystem and using a custom command-line tool, making it accessible to agentic programming tools. (No MCP though; it seems superfluous?)
I was fairly neutral about the tool for a while, but lately I've been going all-in on Claude Code, using things like rules and subagents.
It's also built to "rerender" the story, for instance rewriting it (slightly) for voice, translate it, or target different reading levels or background. I'm interested in translating stories for language learners in addition to simply translating into other native languages.
I'm also hoping to create some stories that stretch the medium. Perhaps CYOA (though I'm struggling with understanding what a CYOA is good at), though also other multi-perspective stories with reader autonomy in how to read through the story. LLMs make it easier to overproduce content, so you can give the reader flexibility without feeling regret that much of the content will be skipped, or rewrite passages for readers who jump into stories part way through.
Producing quality content is hard, and frankly kind of expensive, which is why I'm focused on finished products instead of interactive experiences. Though I do look forward to some future opportunity to take these rich characters that are grounded in full stories and find other things to do with them.
I'm working on Mizu, a small Go web framework built around a simple idea: net/http is already good, frameworks should not fight it.
I've kept running into the same problems in popular Go frameworks: hidden context mutation, magic middleware ordering, reflection-heavy binding, and APIs that slowly drift away from the standard library. The Gin ecosystem in particular has accumulated a lot of technical debt and footguns, which this post summarizes well: https://eblog.fly.dev/ginbad.html
Mizu is deliberately boring by design:
- Built directly on Go 1.22 http.ServeMux
- Explicit middleware chains with clear scoping
- No reflection, no codegen, no global state
- A real request context type that still interoperates with net/http
- First class graceful shutdown and error handling
If you're happy with net/http but want slightly better ergonomics and structure without losing control, that's the gap Mizu tries to fill.
i made a clone of beads in rust that uses CRDTs for real time sync to coordinate a bunch of coding agents at the same time! if running locally, it's instant, for git it takes around .6s after your last action. lives entirely in git, and is like... an actual distributed database/issue system, just works, and u never gotta think about it.

I’ve been getting back into movies this year and my 2018 laptop has reached the stage where it’s no longer useful as an everyday tool, so I’m turning it into a home media server.
I’m only a couple days in, and I’ve already learned so much about networks, containers, codecs, ffmpeg, and so on.
This is the first vibe coding platform to create personal apps that run entirely on chat starting in WhatsApp. We already have some beta customers building and it is really exciting to see what they are using it for:
-wine inventory tracker (lets you rate the wines that you drink and own)
-outfit planner (has an inventory of all your clothes)
-expenses tracker for trips w friends
-personal training coach (keeps track of all the muscle groups that you have used with the purpose of eliminating muscle compensations)
We are quickly releasing beta access for people in the waitlist! Would love to have more people using it.
An algorithmic trading hedge fund. We can outperform the benchmark while keeping fees bare minimum because all our admin is outsourced to LLMs and agents. What a world we live in.

Puzzleship - a free daily puzzles website with the archives paywalled. Right now it has Logic Grid Puzzles and Zebra Puzzles. I'm pretty proud of the LGP generator algorithm and some experienced players also liked the way the puzzles are constructed. This is my first subscription site and it's been online for about 15 days, so I'm learning a lot and trying to figure out the pricing.
Building an app for winter sports. You can download the map for a ski resort, and use the map to see where individuals in your group are, and suggest meetups (summits) on the map, and everyone gets a personalized route generated to that point.
I don't have a link to share just yet, but I'm working on an LLM coding agent that can modify its own context and is given hints on when and why that would be useful.
I expect it to make it possible to not think about when to reset back to a clean session. I also expect it to be more efficient as it will clear out all the "garbage context" that only serves to "confuse" the LLM, cost more tokens, make responses slower, etc.
Once I get a working prototype, then I will test the feature by using it while reimplementing it in other open source agents to get a feel for whether it has the effects I'm expecting.

Thank you for that feedback! Yes - I do plan on upgrading to a real external microphone soon. For the time being it is the camera's internal mic, which is admittedly, not great.
A small tool that does one thing: publish Markdown and give you a link—no accounts, no setup, no project scaffolding. Paste or write Markdown, click Publish, and you get a human-readable URL you can share immediately. You can update or delete the page later using the same link.
The idea came from frustration with how oddly hard it still is to put a Markdown document on the web without turning it into a repo, a static site, or a login-gated doc. JotBird is editor-light but publishing-first, and I’m now exploring CLI and editor integrations so it can act as a simple publishing layer for tools people already use.

Adding more LSP features to the jinja linter for saltstack that I wrote, so you can see all the bugs in your templates from VSCode (rather than waiting for CI) and do things like “rename this jinja variable everywhere it’s being used”.
I've been working on a game for playdate, part time for the last year+. It's a wonderful device and community. The hardware constraints are extremely freeing, and inspires creativity. Mostly Lua, but if you want to push the boundaries, you need to go fairly low level C, and I've found pushing in those boundaries to be just a blast. It's great platform if you're interested in a game dev hobby.
Working on an AEO engine which focuses on optimising webflow website so they show at searches when someone is doing at chatgpt, perplexity and other tools.
It's a webapp that lets you create wish lists and share them with family and friends. The key feature is the claim system: when someone decides to buy you an item, they can claim it so others know it's taken, but you never see who claimed what or even that it was claimed at all. The surprise stays intact. You can also split big purchases. If someone wants a $400 stand mixer, multiple people can chip in allowing family tight on cash to feel like they're contributing without having family members feel like they have to put small items on their list just so everyone can contribute.
I kept it deliberately simple. No social features, no feeds, no ads. Just lists with items, links, prices, and notes. You create a list, share the link, and you're done. No group chat gymnastics required. It's free to use. I built this because I wanted it to exist, not because I had some grand monetization plan. You can sign up and create lists without a credit card.

I'm working on Ward, a Chrome extension that detects browser scams/phishing using lightweight LLM models. Our target persona is elders, young children, and anyone who's not as tech savvy. When explaining it to people, I call it a "modern antivirus", because it can detect anything from malicious scripts on a page to grey-area misinformation on social media.
I'm bootstrapping and covering LLM costs for Ward's first couple hundred users (got about 50 users at the moment) to improve it. We have a local mode for added privacy and are dipping our feet to gauge biz. interest (client-side phishing protection is unparalleled).
I've recommended it to friends, colleagues and loved ones. I dogfood my own product, and it even surprises me every day how much more mindful it makes me of my browsing of harmful content. Would love to get feedback and testers from HN.
TLDR the incremental compiler rewrite is finally bearing fruit. Namely, because we no longer have a batch compiler (i.e. we don't bail on the first error), we can
- provide LSP results (hover, goto def, etc) on non-broken parts of your isograph literals, even in the presence of errors
- surface those errors in VSCode, and
- fix those errors with auto-fixes!! (https://www.youtube.com/watch?v=6tNWbVOjpQw&t=314s) Which is to say, select a field that doesn't exist, and let the compiler create the isograph literal declaring it.
My initial goal is to make a functional SillyTavern (AI roleplaying) replacement. SillyTavern builds prompts from a few rigid buckets (character, scenario, lore, system prompt, author's note...), which makes complex setups hard to manage. Content gets duplicated, settings have to be toggled in multiple places, and it’s easy to accidentally carry or modify state across conversations. Over time, it becomes difficult to tell what context is actually in effect.
I’m building an alternative that treats context as small, reusable pieces that can be composed and organized flexibly, rather than locked into fixed categories. Characters, settings, and behaviors can be mixed, reused, or temporarily enabled without duplication or manual cleanup, and edits preserve clear history instead of rewriting the past. The goal is to make managing complex context deliberate and controlled instead of fragile.
Although I’m trying to get the functionality required for roleplaying done first, the app is generic enough for other AI workflows where fine-grained, explicit context control is an improvement over existing chat interfaces. Think: start a new conversation with an assistant and start checking off rules, documents, and instructions to apply to the chat. Regenerate responses with clarifications or additional one-time context layers.

It uses your existing subscriptions and supports all the major CLI and API providers. There's no cloud features of Omnispect itself, it runs locally except for calls to the LLM providers.
Claude Opus 4.5 is used as a routing agent, which selects the most appropriate LLM provider and model tier to delegate a task to. For example, the routing agent might delegate a single large task to GPT-5, which in turn delegates multiple small tasks to Haiku agents in parallel, then Gemini reviews all the work.
Omnispect lets you view the delegation tree of prompts and responses that spawn from your initial prompt.

A few years ago, I made a model skinner for Tribes 2, a ~25 year old game that still has a loyal following: https://exogen.github.io/t2-model-skinner/ (if you check out the Gallery link there, you'll notice this app resulted in a whole new wave of skins, and even a Halloween skin contest)
To satisfy the urge of doing something else ambitious in the browser, I'm now doing the same thing for Tribes 2 maps: trying to make a web-based map viewer and editor: https://exogen.github.io/t2-mapper/ (editing/creation part still in progress)
I got this working for most maps pretty quickly. It translates the mission object tree from the Torque .mis files into a Three.js scene graph. Eventually though, I noticed that some mission definitions were more dynamic – Torque .mis files are really just TorqueScript .cs files with a different extension and some pragma/magic comments. So, to actually handle every map would require not just a mission file parser, but a whole TorqueScript runtime. Implementing THAT part seemed really tedious and, frankly, uninteresting to me. So I had Claude Code get a whole TorqueScript transpiler and runtime working. Now, when you load a mission, it actually runs all the same scripts that Tribes 2 runs to load the mission, all the way from server.cs and its `CreateServer()` function.
Currently, I'm continuing to get its rendering matching Tribes 2 as closely as possible, and setting things up so that live editing of missions will work.

Do you mind elaborating more about the use case? Postgres itself is heavily engineered around OS process boundaries for both correctness and resiliency.
I'm not sure it'll be a serious project, but the main goal is to use it in CI or dev, where setting up postgres is kind of a pain.
I got it to work already by setting up the global context in single-user mode (like postgres --single) and exposing bindings for SPI operations.
Yesterday night I got extensions working, but as this project builds as a static archive, the extensions also have to be part of the build. Both plpgsql and pgvector worked fine.
The bigger challenge is dealing with global state -- comparing the pre-start and post-shutdown state of the process memory, about 200 globals change state. Been slowly making progress to get restarts working
Hi HN — I’m Gerome, and I’m working on CodinIT.dev.
TL;DR: CodinIT.dev is a local-first, open-source AI full-stack app builder that turns natural-language prompts into prototype → production web apps. It supports local/self-hosted workflows, connects to databases (Supabase), includes an integrated terminal and git automation, and plugs into 19+ AI providers so you can iterate fast. Download desktop app at https://codinit.dev
.
A few quick facts
What it does: Generate full-stack code from prompts, preview instantly, and deploy anywhere — built for indie hackers who want full control of there code without vendor lock ins (open source).
Where the code lives: active repo and org on GitHub — org name is codinit-dev.
How to try it: download and run locally; the dev flow runs with pnpm run dev and serves locally from your machine.
Progress & current priorities
Stabilising the live code execution sandbox and improving safety/UX for file uploads and agent orchestration.
Tightening integrations with community LLM providers and adding more framework templates.
Improving contributor docs and reducing onboarding friction so people can run it locally without hurdles.
If you want to poke around, try the app or the GitHub org and open issues/PRs. I’ll hang around to answer technical questions here.
Something small that has been on my mind for the past decade or so -- assistant chatbot.
Basically I long wanted to plug a chatbot into my messenger of choice with all sorts of tools for quick use, of course after the emergence of LLMs it was only a matter of time before I find time for it.
As an experiment I have decided to use Claude code + opencode to develop it, and after some trial and error I am very thoroughly impressed with the results, it grew to a nearly 10k LOC in a week and it is still very much manageable, I haven't changed a single line of code manually still.
I have developed it as a "core" that imports modules with a rigid and thoroughly documented in a spec.MD file interface, and every single bit of functionality essentially acts as a different sub-app that can consume events that trigger it and handle all of the internal logic within itself, that way everything is separated nicely and totally manageable within LLM context.
It does everything from setting up and sending reminders and todo lists, helping me track car mileage and fuel consumption, getting an overview of the day ahead(sometimes if task is important even a reminder few days prior to its date), to even opening my front gate. And all of that is exposed to 'core' chat module through tool calls, so I can request anything in plain English or voice.
Also has a web-ui where I can review tasks, reminders, settings or search past conversations.
Been using it a lot, and since I'm using groq for inference, I still haven't even needed to pay a thing, since it fits within the free limits

I mentioned this a few months ago, but have made progress since - I'm working on an alternative to subscriptions for online publications. Instead of subscribing to entire publications / blogs, publishers would register their publication on this network and configure thresholds and pricing. Add a bit of code to the site and a paywall will show up, allowing readers to pay for individual articles. The prices would be minimal, amounting to less than a dollar in most cases. i.e. reading articles using micro-transactions
I know it's been tried before, but I thought I'd attack it with a few different angles - web based, no chrome extension, thresholds to help verify the article is worth it, extensive use of an aggregator to help with discovery and validation.
I've been taking some time off from https://gethly.com, as majority of functionality I wanted to implement and offer to customers is done, so it's mostly just some tweaks here and there.
I was pondering doing something in regards to decentralised consummation of content. I am beginning to see how various websites are walling off their content and centralising everything whilst also monetising access to it for themselves and kicking content creators out, forcing them to run their own websites and use multiple backup platforms(mostly the dying youtube).
So I was thinking about flipping it on its head and instead of going to different websites to consume this content, like youtube, twitter and whatnot, people would have a single program to aggregate it instead. Then it occurred to me that this is what RSS/Atom was made for, kind of. So I am just letting the idea marinate for a bit and maybe next year I will look into it. Mastodon might have some good concepts in it that I want to look into and also come up with some standardised way for richer content that creators could provide beyond RSS to make it more palatable and easier consumable for users.
I'm thinking about creating a brilliant.org clone (the old version, not the current enshittified one) but entirely community-driven and open source:
Besides the classical features (create/delete,edit your own problems) you can also have courses and collections: courses are a ordered sequence of lessons and problems, lessons are post-like entities that can contain text, images, animations, embedded videos through links, latex, code, ...
Collections are just a ordered sequence of problems (ideally it is a progressively difficult path of problems, but this feature can be used for anything you want). It would also feature a wiki, and eventually a forum for discussing/administering the website.

I'm soon to beta my first macOS app: AlgoMommy. AlgoMommy helps you organize your video clips prior to editing them in Final Cut Pro / DaVinci Resolve / etc. It replaces the manual and time-consuming process of "filing" your newly-recorded video clips (CLIP_5213.mp4, CLIP_5214.mp4, ...) into a sensible folder hierarchy (Wedding/B-Rolls/, Wedding/Reception/, ...), so that you can focus on creating and your content.
This has been a fun project so far for me:
* First time using Claude Code. CC has made writing code fun again (I'm an experienced software developer, with - gasp - over 20 years of professional experience).
* On macOS, WhisperKit + Apple Intelligence (SpeechAnalyzer) is a powerful combination for offline transcription.
If you're interested in joining the beta, feel free to send me an email: diarmuid.glynn@gmail.com. The software is working now, but the documentation and website ( https://www.algomommy.com/ ) are unfinished, so I'd like to provide direct support to any interested beta users.
Working on a visual language learning app called Snapalabra!
The idea is simple: You look at an image and describe what you see in your target language. That's basically it!
My reason for building it was that even though I can understand a lot of spoken spanish, I really struggle to construct sentences on the fly when speaking. Doing a few minutes of active learning like this each day really helps remap my brain a little, and I quickly run into situations where I hit a wall and realize I actually don't understand something as well as i had thought.
The app also gives a little feedback on what i have written from an llm, and it also provides clues that I have mapped to each image.
At the moment I am using it mainly for intermediate Spanish and beginner Irish, and personally I find it really helpful for both. Basically learning vocan for Irish, and more serious sentence structure etc. in Spanish.
I know a lot of people absolutely hate the idea of mixing LLMs with language learning, and I can kind of see why, but I personally find it really helpful in certain cases. If you are already doing classes, and consuming content in your target language I think something like this will be really helpful for a 5 minute coffee-break type activity in the morning. Its not a language course and I have not intention for it to be one. Its just a supplementary little tool that helps with getting your brain thinking in a new language and it is free to use.

Custom Copilot alternative / extension because I no longer believe it is a good idea to let Big Ai determine how you write code with your new helper. Big Tech f'd up a lot of things the last 25 years as we ceded control of our interfaces to them. I don't want to make the same mistake with my primary work tool.
Also, getting into the guts of how agents work and messing around with the knobs and levers is super interesting and where the real differentiating skills are
I don't want to sound rude, but what was your reason to go from scratch instead of joining an already established, open source effort? The likes of Cline, Roo, Continue, ...
The three options you offered are all VC funded "open source"
This is where the real AI bubble is. VC funded startups who's main plan is likely an acquisition. I'm not interested in those kinds of "open source" anymore, they want to lock you in to their product. Also, https://ssotax.org/

Back in the day I worked (briefly) on a deep sea polymetallic nodule mining startup, and so just for fun I've been building a simulation for it. It's been done a million times before but I wanted to do it myself in project chrono using their granular terrain and old polymetallic nodule samples I have
It's in a pretty early stage of development though, I haven't added my samples yet and nothing is to scale. It does run though which is neat https://github.com/thansen0/seabed-sim-chrono
I got so sick of not being able to find good driving routes that I'm working on https://shuto.app but also because Waze wants but to cut through London for my current contract gigs rather than take the M25 sensibly I'm also working on having the algo handle that for default. Testers would be appreciated if you ping me below though at anosh@ below link.
• I've never been satisfied with music players on iOS, so I'm making the definitive one. It works with every personal media server, in additional to local files and Apple Music libraries. It'll do some stuff that no music player has ever done.
• I open-sourced and released some iOS dev tooling I built for Claude Code that multiplied my personal coding productivity: https://news.ycombinator.com/item?id=46264591 Nobody cares yet, but it makes me feel good to share something cool.
Just released the browser extension for https://unrav.io . It transforms any article, paper, or YouTube video into your perfect view (infographic, TL;DR, mind map, podcast, etc) with one click.
It’s for people who feel smart but overwhelmed, drowning in tabs, skimming everything, remembering nothing.
You don’t need more information. You need clarity.
Hacking GTA V’s graphics pipeline to get access to the depth buffer, so I can feed it into a self-driving machine learning model. There’s already tools that do this (ReShade & other DX11 hooks) but I want to learn how to do this in general for other types of data & processes.
On a personal note, I’ve been trying to lean into my fears more. Disassembling binary was always something I knew would be helpful to know but I kind of avoided, so I think this is helps with that a little.

A CNC simulator that runs in the browser or as a PwA. I wrote this mostly for myself to compliment a g-code sender I am also working on https://mycnc.app/ . The simulator has some basic g-code and cut verification and analysis built in with more to come.
I am learning hobby CNC having come from the 3D printer world and I found that the CNC software is considerably more complex than today's 3D printer software.
CNC seems to be the next hobbyist maker boom with the likes of Makera and Nestworks having very successful Kickstarters.
I'm working on a simple IoT visualizer. I built my own domotic system at home (which i hope to turn into a product at some point) and I had the need to visualize the sensor data per room and per floor.
While I was working on the tablet interface (in Godot Engine) I put Claude to work on what after two minutes became a full product on its own with a new file format as well. Tell me what you think! (so far the response is meh...)
On and off, I am currently coding a minimal wayland compositor for linux and AMD GPU(no libdrm), in RISC-V assembly (64bits), which I run on x86_64 with a small RISC-V machine code interpreter written itself in x86_64 assembly. I do not use ELF, but a file format (excrutiatingly simple as such file format type should be on modern hardware architectures) of my own with an ELF capsule (also written in x86_64 assembly).
I start with SHM memory, will add linux dma-buf once SHM is enough up and running. Currenty monothreaded, ofc. AMD GPU code for SHM is in, now writting wayland protocol code to please the first wayland clients I would like to run (not using the C libraries provided by the wayland project, native wire format).
I want to move away from x11, and once I get something decent with this compositor, I will probably have to fork xwayland in order to make it work with this minimal compositor, that for some level of legacy compatibility (steam client/some games).
In the end, I did design some kind of methodology and coded some SDK tools in order to write a bit more comfortably RISC-V machine code programs in a very simple fire format (only core ISA, not even compressed instructions, no pseudo instructions, using only a simple C preprocessor).
Coding time does not matter on such software in the light of their life cycle once it does "happen".
All that presuming not too much IRL interference... yeah, I know this is excessive to expect that...
The super hard part is not coding, it is motivation: energy, mood, cognitive bias, etc.
I'm not working on anything at all. I'm stuck in SAFe planning meetings for the next week. I fucking hate the whole thing but they pay me to sit there and watch others play with their Miro boards, so Merry Christmas you filthy animals.
I’m building a netsuite competitor (having spent a lot of my career on accounting and erp implementations.)
The trick (one trick) is to allow LLMs to provide an audit/accounting/compliance playbook, along with customizations, based on the user describing their business model.
We are building a K8s management platform based on AI Agents and smart visualization. It's surprisingly hard to distill common issues down to generalizable agents which can solve real world issues but we've made some very exciting progress in the space.
I run a small logistics platform called Twinjet that is used by mostly food delivery courier companies. One of our main features is parsing emails from food ordering platforms in order to automatically add the delivery job to the company's dispatch board. These parsers need constant maintenance since the ordering platforms change their email formats all of the time.
I'm putting the finishing touches on an AI parser that I hope to ship after the new year. I'm getting very consistent results from Ministral-3b model, which is super light weight.
A few games developed entirely with AI. I'm using GitHub CoPilot to drive the development, and I'm having the AI come up with the graphics programmatically as well. It's a pretty fun project.
Just submitted it to Apple for review this past weekend... basically Scapple's visual text canvas meets Workflowy's hierarchical focusing. I mainly wrote the app for myself to organize my thoughts. Very happy with how it has turned out.
Edit: Would be interested to hear why this was downvoted?
I am hunting for the source code of VR-1 Crossroads
It was a mud style game in beta that ended up getting axed in the early 2000s (?) but it was brilliant and a few of us stuck around in it long after we should have.
If anyone has heard anything about it, let me know!
I'm building personal, minimalist, website monitor in Gleam using the Erlang OTP.
In the time-honored hacker tradition of added more problems to the problem i'm trying to solve I'm learning a new language (never done FP before, either), building the product I wanted, using the latest crop of creative tools, and treating it as a little end-to-end business startup too. Launching in January!
I am trying to make a game that sits squarely between AE2 style request-based on-demand crafting VS fully passive production akin to Factorio :) Making games is fun!
https://deepwalker.xyz - Mobile Agent, can bypass cloudflare,sms,email validations and some captchas. You just need a cheap android phone and plug into your computer. Deepwalker takes care of the rest.

We're focusing on "anti-cloaking" for anti-phishing and other Internet security applications at the moment. Phishing sites can "cloak" themselves so that they present malicious content to ordinary users and benign content to bots, and thereby evade detection. Anti-cloaking is doing things to defeat cloaking.
The methodology is to operate a site that logs all requests, and collects information from the JavaScript environment, and looks for signals that a session is being operated by a bot instead of a human. We have 183 unique signals so far.
We've seen fake mobile phone APIs being injected into the DOM, and have been able to read out the source code implementing them. We've seen lots of people running the browser with TLS validation and same-origin policy disabled, which are both easy to probe for. And we've even seen people running services on localhost with CORS headers that allow cross-origin requests, allowing us to read out their server headers and page contents and which would allow us to send arbitrary requests to their local servers. We've seen people using proxies that don't support websockets. We've even seen surprisingly-big companies scanning us from netblocks that just straightforwardly name the company, which would be trivial to block just by IP address.
It turns out that every security vendor that scans VirusTotal submissions or domains from CT logs has major flaws in their headless browser setup which mean it's worryingly easy to cloak from them.
I don't know the best angle for monetisation. Currently we are selling "quick overviews" of what people are doing wrong, but it kind of feels like we're giving away too much value too cheaply. However it's difficult to convince people that there is value worth paying for without telling them what they're doing wrong upfront before they pay. Ideas include:
* automated quick overviews, where we give you a URL to point your bot at, find out all the signals you hit, and give you an automatically-generated report of what you are doing wrong
* or a manual "pentest" of your headless browser, where we do the same thing but spend a few days manually looking harder to see if there are new signals we're not yet spotting automatically
* or we could sell a report of the state of the industry as a whole
* or access to our tooling
* or something else
I have been told that if I say it's for anti-phishing then I have 12 customers max but if I say it's for AI browser agents then someone will give me a billion dollars. So possibly we need to explore other applications, like either telling AI scrapers why they are getting blocked, or else helping sites block AI scrapers (though I am personally opposed to building the apartheid web).
Open problems are:
* what's the best form to sell it?
* how do we satisfy people that if they pay for a test then they will get value from it?
* should we pivot away from anti-phishing?
* for bots that we notice have found us from VirusTotal or CT logs, how do we work out who is operating them so that we can sell to them? Sometimes attribution is easy but in the majority of cases it is not
I cannot say what I'm working on because it will be downvoted. Only pointless gimmicks which do not compete with the tech oligopoly can get any traction nowadays.
If I make a really good AI coding platform which saves people hours compared to existing platforms and provides more security. The chance of success is 0 because it's competing with incumbents.
If I make an app which allows cats to order food and back massages from their owners, this has a high chance of success.
Testing out LLM based content moderation tools, but on code mixed content. Content is not typical pure english content. Mostly its been a journey in getting data and then fiddling with policy.
Just finished a major (v0.10) revamp of the API (you can use connet as part of an application, not through the CLI) which also fixed a few issues I've been seeing before.
Now, I'm gearing to update the relay protocols - currently relays are closed off by the control server (e.g. you ask it to provision you a relay resource) which requires the relay to communicate with the control server itself. In the new version, the relays will be operating on their own (there might be a shared secret with the control server, in case you want a closed off relay) and peers will reserve directly with the desired relays. Maybe in future, the relays might form clusters on their own to take advantage of better relay-to-relay network and peers will reserve only at the relay closest to them.
Another stream of work, is giving peers identities. Right now the server will give them an internal identity to better support reconnects, but these are not stable (e.g. they don't survive client restarts). In future, the peer will advertise their identity and then other peers may choose what peers to allow comms with and what to ignore, pushing more decisions into peers themself.
Yet another change I'm thinking about is exposing raw endpoints to enable users of the system to implements other protocols - I'm not quite sure if this is really needed (the destination/source, e.g. server/client) covers a lot of ground by itself, but it would be great if these are not the only options.
Many options how to continue, but if I'm out of ideas, there is always a Rust rewrite to throw in /s
Actually, I realized that I've used `/s` incorrectly. I've been thinking about rewriting the clients in Rust, mostly to allow simpler embedding in other languages - java and swift for example (I think it would be great if connet was available on mobile - for android you can Termux to compile/run it, but it is a pain). This will make it harder to embed in golang tho.
Another option is to try to rewrite clients in each of the language, but most fare poorly on QUIC support - in Java for example, I'm not aware of one that is advertised as production ready (looking at kwik with their fork of TLS).

An PWA primarily for my wife and my daughter. They can order their hot chocolate and their coffee as if they were going to grab something at a fancy café downtown, but instead it's at home and I'm the barista. It is quite nice to have for when my wife comes back from work and want something specific, or when we are waiting for the visit of a few friend, they can order exactly the available beverages and everything is ready when they're here.
It was also a good playground for me to implement Web Push notifications (to never miss new orders).
It's a basic Nuxt 3 app with Appwrite as the backend with rough edges, but much enough for our household use !
If you want to spam my phone with notifications, please visit my café : https://mytinycafe.com/alix
LOVE this. Are there any plans to open-source? I'd love to run my own instance.
Also some feedback: the ordering buttons are inexplicably in french despite everything else being in English. Choice of language or defaulting to English would be expected...
Also - multi-select and nullable options. So that I can create options like Taco / Steak / Pasta, and add side options that are relevant only when one of those is selected.
It's open-source now : https://github.com/Karalix/micro-cafe
have fun :)
If there's a demand for it to become open-source, why not? But I'll have to improve code quality first. As the presence of french labels indicates it, i18n is not properly implemented for this project.
No, you really don't have to. Partially complete software can have a lot of value too.
Anyone can fork it and quickly add the i18n (or just translate into a different language) for their own purposes. People will likely want to contribute i18n. People may fix or improve things for you.
Of course, it's entirely up to you - but I've appreciated half-complete software countless times before.
> But I'll have to improve code quality first.
Don't fall into this trap, strike while the HN iron is hot, all these people +1'ing will never come back when you're eventually happy the code quality is "improved"
If it's truly that bad you'll benefit from the feedback since it's an internet exposed service, although considering you're a professional freelancer, I'm sure it's fine.
It is far from fine. It was my little dirty project where I knew there was only 3 users and where I could be finally escape the usual process from my professional life.
But heh, now is the Time for me to patch all the hole I left. Lots of coffees depend on me now.
Si c'est open source je peux aider avec les traductions !
And yes, I feel like, working on it before open sourcing it is like cleaning before the cleaner. It's ok if the code is messy and there are bugs, that's why OS exist.
Very cool idea imo congrats
*source ouverte?
ahah le cloud infonuagique en source ouverte
There's demand for it, add me to the list who wants this and would use it
I'm definitely interested! My family would love this.
Me too
+1!
Me too
+1 interest!
Any plans to open source?
PLUS, to sweeten the deal. here’s a bunch of tech support!
this is awesome! my wife and I host coffee for neighbors on saturdays and this would be perfect for that!! thank you
Do not worry about cleaning up the code before open sourcing it. Get it on GitHub and I am sure plenty of us would open PRs. I know I would!
It's live on Github now !

Bug report: I tried to create a new cafe with a name that contained a space character in it. The form told me the ID was invalid but seems to have created my user account anyway. When I log in now, the CafeID I get is 'undefined'; as in, I am now the proud owner of https://mytinycafe.com/undefined/barista. I'm assuming this is not intended :)
Hey, that's MY cafe! (same bug happened to me)
Just had a look at the control code. I must have been drunk because it is totally idiotic. I am surprised it took that long for it to be reported on HN
So cozy. I love this.
One nit: the contrast in dark mode at least on the marketing site is a bit off (But I'd love to fix it myself if it was open source :) )
Very cool concept - thank you for sharing it! I think would be a great solution to the near-daily "what should we eat" problem.
If I could make a (not-important) suggestion, I think being able to re-arrange / categorize menu items would be useful. Something that lets you group together drinks apart from snacks as an example.
The "what should we eat" problem was a big source of tension in our household since the arrival of our first child. Too much time-consuming, too much planning effort. What changed our life (and I really mean it) is the app https://jow.com: it suggests you a list of meals for the week suited to your family and equipment, and it creates a shopping list for your preferred delivery provider. I only have good things to say about it and could go on for hours.
We're actually in a unique situation where the planning+buying isn't the hard part, but the deciding is. We're within walking distance of a super-cheap grocery store and I'm able to cook a wide variety of dishes - many of which I can make quickly. The hard part is my wife doesn't do well with open-ended questions like "what would you like to eat"? Seeing a discrete list of things I can make and her just picking/submitting the options would solve the problem.
Though that only holds while we have free time. If we have a kid, then I can see a great amount of value in that app.
I posted this in another comment but couldn't help but notice this discussion since it seemed relevant. I've been working on https://mealsyoulove.com, which is a meal planning app that also integrates with Kroger and Instacart for ordering groceries. Jow looks similar (not sure what their pricing model is?), but I'm leveraging AI to build highly tailored recipes and meal plans while allowing you to also import your own recipes to incorporate.
This is lovely,I thought about doing something similar but as a 'Dads taxi' app similar to Uber where my family can request rides. Partly because I sometimes struggle to remember where I supposed to be and when, but also because it might just be fun
I really love the idea of an ecosystem of Apps Powered by Parents (APPs). Please reach out if you ever plan to implement it!
Also helpful if you have teenagers and want to make it easy for them to not drink and drive
Awesome! I like when imagination fills the gaps of technology, maybe because I played on old computers like spectrum, we had few pixels and had to imagine the rest.
The ordering could’ve been “solved” with a WhatsApp message, ( or shouting ? :D ) but that would have been so boring!
This much better life UX !
This app is a reminder of being playful and imaginative in life can bring joy, congrats!
Super cute! Might try it out soon (my partner and I are both working from home most of the time).
I love this concept and the execution.
This is awesome. Perfectly solving a problem, showing off tech, and adorable.
I never expected to open this and find something that would put a big grin on my face.
Thank you for giving me some joy.
FYI: The features section of the website doesn't render correctly in dark-mode.
You should add food and prices too. Obviously you don’t need to implement an actual payment system because it’s for fun, but if it kept track of the money, your kid could charge you 0.50 per drink or something.
That's a nice idea ! Will definetly add it soon.
And for the food, one can already add anything, it's just a text field. A friend of mine only has alcoholic drinks and snacks on his menu page.
Lovely idea! One Latte for me :)
Oh man this would kinda help me a lot right now. (As a struggling home owner living w/mom and dog)
FYI this is a blank page on Firefox :(
works for me Firefox 145.0.2
The testimonials section is adorable
so it's a point-of-snail sort of system, perfect for taking share in a teeny tiny market, and in the growth-share matrix something of a Cashless Cow?
This is adorable. Nice work!
I like it. Delightful.
The URL is public e.g. for /nick (me)?
Yes, the url is public :)
This made me ovulate, and I'm not even a woman.
I love it! Such a cute application :D
It's really super cool!
This is so delightful!
Slightly disappointed to realize there is not some automated drink machine behind this, as that's more my interest, but cool nonetheless and you handmade drinks are probably better.
I'm working on porting KiCad to the browser. It's a lot of sweat and tears, multithreading issues and some more sweat. I've updated a port of WxWidgets and now I support all the features KiCad needs with ~200 tests.
Right now I have a build that loads in the browser, but I really want to have "multithreading" which means workers in the web. One can use asyncify with emscripten to translate blocking C++ to WASM, but that transition is not perfect, right now I'm debugging a bug where there's a race condition that halts all execution and the main thread runs in an infinite loop waiting for the workers to stand up. I guess I'll have a few of those ahead.
The main goal is to 1. just have fun 2. use yjs as a collab backend so multiple people can edit the same PCB. This will probably work with pcbnew, KiCad's layout editor, since it has a plugin system and AFAIK I can do the sync layer there. For the rest ( schematic, component editor etc. ) I'll have to figure out something.. KiCad does not sync automatically if you modify a file, I'll have to do some lifting there.
Anyway, it's a lot of fun, I really want this thing to exist, I'm hoping that I won't run into a "wellll, this is just not going to work" kind of issue in the end.
That's super cool! Not needing to install is great for accessibility for new users, and I think this would also be cool if it can be embedded into other websites as a viewer (like imagine opening up a Git repo with KiCAD files in it and being able to explore them in an integrated viewer)
That's a neat idea! To be honest my brain is overflowing with ideas too, right now I want to just bring all the apps one. Or... Actually just bring the layout editor up first :) I'm trying hard to live in the present...
Excellent. kicad is cool; zero install should be a good gateway drug.
I just finished a dsn parser and now I am planning to write a pcb router. All in rust. The plan is to have a wasm/wasi version as well so routing is possible in the browser.
Very interesting. Is it or will it be open source? Any links?
dsn parser is open source, https://github.com/dilawar/dsn-parser (WIP). Some part of PCB routing will be open-source (MIT).
This is a great project! Thanks for tackling it!
Awesome Project! Would love to hear more!
Heyythanks! Feel free to bug me at viktor.vaczi(at)emergence-engineering.com I'd love to chat about it :)
Have you checked out circuitsnips and kicanvas?
I did check kicanvas, but I didn't know about circutsnips, I had the same idea for years! It's great!
That is very cool. I can't wait to try it out!
Connecting the dots from agents to workflow automation to infrastructure with Taskade Genesis.
LLMs made it easy to generate apps. The harder problem is running them as real businesses. Where they live, remember state, coordinate agents, trigger workflows, and keep operating day to day. We treat the workspace itself as that layer.
One prompt becomes a living system. CRM, ops hub, internal tool, business in a box. Memory, agents, and automations working together. Feels closer to early web hosting than modern SaaS. Not demos. Real systems.
Still early, but builders are shipping real internal apps and workflows, not demos. Excited for the future of AI from productivity to agents and workflows to Infra!

Completely free, no ads, no in-app purchases and no accounts / network required offline voice transcription.
I have also built the macOS/Windows/Linux versions which I'll also make free to download and available on my site soon (https://blazingbanana.com/).
iOS version is built and works (extremely well), just waiting for the Apple Developer signup process to complete.
Big shout out to https://github.com/mybigday/whisper.rn and https://huggingface.co/ggerganov/whisper.cpp/tree/main for making this even possible.
Any suggestions are welcome.
On the subject of whisper being great... A few weeks ago a co-worker commented about the difficulty he'd had editing a work demo, I pointed at various jump-cutting tools that had automated what he did in the past (editing out silences). But I'd also wanted to play with whisper for a while...
So a couple of hours later I'd written a script that does transcription based editing: on the first pass it grabs a timestamped transcript and a plain text transcript for editing; you edit the words into any order you like and a second pass reassembles the video (it's just a couple of hundred lines of python wrapping whisper and ffmpeg). It also speeds up 4x any silences detected that sit within retained sequences in the video.
Matching up transcripts turns out to be not that hard; I normalise the text, split it, and then compare to the sequence of normalised words from the timestamped transcript. I find the longest common sequence, keep that, then recurse on the before/after sections (there's a little more detail, but not much). I also sent the transcription to ffmpeg to burn in as captions, because sometimes it makes the audio choppy and the captions make it easier to follow.
I know, tools have been doing this for years now. I just didn't have one to hand, and now I do, and I couldn't have done this without whisper.
That is absolutely awesome and I love hearing about the tools that people build themselves!
Honestly, the capabilities of whisper is insane, the fact that it's free and open source is really a gift. Some of the things it can do feels almost sci-fi.
If you ever decide to release it publicly please let me know, sounds like a very useful tool.
Couldn't find it on the Play store by searching for the name and the developer's name: if it is not just me then your app is very hard to discover.
So I am installing it through the link you provided, which directed me to a "install success" page saying "your purchase is successful" even if your app is free. Another obstacle to adoption :-)
Last, I was not informed on the page of the app' size. Seeing what it does and the time it takes to download I am afraid it could be huge? Third obstacle :-)
Thank you for the feedback, I really do appreciate you taking the time to check it out and write out the comment! I'll look at adding a note about total app size in the description, it won't hurt.
As for discoverability / the "your purchase is successful" message, I'm not sure what else I can do, I've set it to free, no ads etc in Google Play. Maybe I need to hit a few more keywords for transcription so it surfaces it more.
The iOS Appstore also treats/words app installs as ‘Purchases’. Always confused my…
For me, searching for "whistle" on play store, I get the app as the third result (ignoring sponsored crap). Searching for "blazingbanana" gets me the app as the first result".
App info shows 218MB size, which I suppose is about what I'd expect for a model+app code :shrug:
Good to know, it's hard to know what real users would see in the play store and not Google just showing you what you want. Thank you for checking it out
Pretty cool. I've downloaded and lightly tested. Works great.
I love the "free forever, no ads part..." But it obscures what the app is for. Maybe start with the "Speech to text transcription" to make it clearer.
Either way, that's just semantics. Great job
Thank you, really appreciate the kind words. I'll take a look at giving the description a bit of a once over for the next release coming soon.
It'd be nice to keep the voice recording too, as I noticed at least one thing that it transcribed wrong.
This way one can listen to the recording again, and correct such issues.
Great idea and an option I'm looking at implementing soon with the ability to reprocess with a different model if needed. Cheers for taking a look.
By the way, how does this handle conversations between two or more people?
Currently, terribly. It is on the roadmap after I've released it on all platforms.
That's very cool, I've been looking for a fully offline transcription app for quite a while. Thanks for building this! And thanks so much for providing an "import audio file" function, not just "record from mic" -- transcribing voice notes from various messenger apps is my main use case here.
Do you have an idea about supporting languages other than English?
Thank you, glad you like it!
The average model and upwards should support all languages from the whisper models by default.
I haven't tested them all so I'm unsure of the quality, however it should in theory support the following:

Apologies for the formatting, not sure how to make it look nice in the comment.
A new bugfix update for the "Translate to English" toggle (which was functionally always set to on) should be available soon, it's just awaiting Play Store approval.
I just tried running this on a 30 minute meeting with some 10 people in. It got to the end, then just bailed without transcribing. I also did not get any errors or anything.
Really sorry about that, longer running audio (~10m+) is something I'm working on along with handling multiple speakers.
I've been focused on getting functional parity across all OS's since the Android release. This is very close to being done and I just need to reach the milestone of it being available on all platforms before I move forward.
Hopefully you will take another look when the next update is out.
@blazingbanana
We have a similar product in the construction space. Would love to talk to you about some of our challenges and possibly work together. Interested?
Very interesting, happy to discuss this privately.
I really liked wisprflow on my mac but my daily driver is Manjaro KDE. I have stitched together a bash script that copies the transcription (right now I am using the Parakeet TDT 0.6B) to my clipboard. I would give this a try on linux when it becomes available.
Just checked out whisprflow, I must say that looks really nice, kudos to those devs. Shame there isn't a Linux / Android version.
I have added the auto-copy to clipboard functionality that will come with the next Android release and be included in all others. Adding a hotkey / quickbar button is on the roadmap for the desktop versions.
If you want to give the Linux version a shot, you can download it from here - https://downloads.formait.app/whistle/linux/WhistleDesktop-l... - I've just stuck it in the same R2 bucket as another app, as I've not sorted the proper pipeline out yet.
Would you be open to sharing your script? I run whisper.cpp in Linux through some stitched together scripts (https://news.ycombinator.com/item?id=44949314), but would be very curious to try Parakeet. I don't believe I can run it through whisper.cpp?
I looked at your script. I am doing basically the same thing just using onnx-asr (installed as a uv tool) with the parakeet model instead of the whisper-cli. Look Here: https://github.com/istupakov/onnx-asr
Would you consider adding it F-Droid?
Yes absolutely! I'm a GrapheneOS user myself so understand not wanting to have to go through the play store if you can help it.
I believe you have to make the source code public (please correct me if I'm wrong). I'm more than happy to do so, I've used a whole bunch of open source stuff to build the app so it only seems fair, I just need to make it a bit less messy and something I don't mind being public.
Yes, not just public, but also licensed under a license that permits free redistribution, modification, etc. This is awesome!
nice app!
if I am talking in german the text is translating it to english. Didn't expect that
Thank you!
There was a bug causing the "translate to english" to be always enabled. This should work correctly and translate to your native language.
Will be in the next update (in a day or two).
I'm working on https://techposts.eu - Hacker News for Europe.
Focused on all the interesting and exciting happenings in tech here, from AI to defence to deeptech, and posting the most interesting job openings too. Did you know Europe had two space launch startups? I didn't until I started this project!
Feedback very welcome :)
Color scheme is a bit harsh for me. I understand you're going for EU colours, but maybe a softer background like #fcfcfc and a more muted blue would be easier on the eyes?
I agree. And I will go a little bit further, why don't do it with a black background? So much white on most websites.
seconded
Great idea, I'm keeping my fingers crossed for this initiative.
I believe that the main challenge would be to get more traction and build a community. Hope you find a way to encourage as many people as possible to join the website.
My very minor nitpick -- I would add some kind of background colour to the main post list, something like #FAFAFA looks fine to me.
Thank you! Please consider signing up and occasionally posting something, it would help a lot.
I'll look at the background suggestion too, thanks!
What are the community guidelines? Is it okay to post personal projects similar to show hn?
Yes, absolutely! The guidelines for now are basically "same as HN, but Euro-centric content please" :) I'll write these down somewhere explicitly soon.
Ooh I like this! I love Hacker news and Lobsters but they're both very US centric, seem great to have a European one.
UI is very nice and simple, one tiny bit of feedback is that a 'guidelines' page would be worthwhile, especially while it's new! I thought I'd post my own project on the site - sometimes that's a little bit of a no-no though, and I couldn't find any guidelines to steer me towards what types of things to share, etc.
Edit: Tiny extra feedback, is upvoting something immediately changes the rankings in the browser. It's pretty impressive speedwise, but especially if you're a couple pages in, you can bump something off of the page you're on which makes it a little weird to do something like 'upvote article and then check the comments'.
Thanks for the feedback and posting, I appreciate it!
I'm definitely going through the comments I've had later and will take everything onboard. Guidelines is a great idea - for now it's basically "HN guidelines but Euro-centric content please" but I should definitely write that down.
Great idea, I'd appreciate an RSS feed
Shouldn't be too hard to do, I'll look into it. Thank you!
The comment page here on mobile
https://techposts.eu/post/68
It shifts out of the screen on the left cutting off the comments. (The problem is probably how you deal with the long url or not deal with it)
Thanks, I'll fix that!
I noticed that you’re using the favicon from Vercel, or that Vercel is using your icon. :))
Great initiative. I was confused by the comment section design. The style of the metadata is not distinct enough from the real comment. And it tooks me too long to understand that the responses to comments were not citations.
Good work, but the headlines are still in „newspaper“ style and not in hacker news style
You mean the automatic normalization HN does when you submit the title? Yeah, it's still quite basic compared to the real HN. I want to validate it properly before investing in lots of features :)
How do you get users to your site? I always felt these products are the hardest to build, but probably the most rewarding ones.
If you could add API on top of it, and make it compatible with HN clients, it would be very nice!
Interesting idea! I was kind of playing with the idea of doing something CrunchBase-like for the companies, jobs and funding rounds. But there's a lot of data out there publicaly too so I'm not sure if it's worth it. Will have a look at the HN clients too, thanks for the idea!
Love to see EU specific. How do you get the jobs posts?
Thanks!
I get the job posts the hard way, from scouring about a dozen different sources, including my own shortlist of "interesting companies".
great! singuped! Just please - get rid of that all blue and underlined links. Its hell to read.
Ha, thanks for the feedback! People have made a few points about the styling, it definitely needs a harder look. Maybe a silly question but which do you find worse, the blue color or the underlines?
Install some custom style css extensions and look at all the HN variations. I like the solarized one.
First post:
> Show TP: TreatyHopper - Pay less taxes
> Treaty shopping is a tax strategy where companies route profits through intermediary countries with favorable tax treaties to minimize overall tax liability.
Can't make this up x)
How would you like your double Irish with a Dutch sandwich, sir?
very good start! I hate to be that guy, but I'd like if you had an imprint and privacy policy on the site ;)
Good feedback! I'll definitely be filling that kind of content in as I go.
Site needs better UI without a doubt.
Copy HN UI as its. no one cares.
Good luck
I'm building a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. We just won silver at the Big Indie Pitch competition as well!
- Currently in free Early Access with 18 competitive mini-games.
- Players use their mobile phones as controllers (you can use game pads as well!)
- Everything is completely web-based, no downloads or installs are necessary to play
- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!
- In the future we plan to open up the platform for 3rd party developers (and Gamejams!) as well. We take care of the network connectivity, controllers etc.. 3rd party devs can focus on developing cool multiplayer mini-games without spending an eternity with networking code and building the infrastructure.
Interested to hear if this resonates with Hacker News readers!
A liiiiiitle more info on the games from your homepage would be nice! Then I can see if it's something worth playing. Which I'm sure it is! Congrats!
Thanks, you're absolutely right! The plan is to make individual game pages with little gif/video trailers and brief explanation of the different games but this is just something that I haven't yet gotten around to do :D
Neat idea. What is the controller latency like when using a mobile phone?
The platform uses WebRTC for connections so in the best case scenario (direct peer-to-peer connection): somewhere between 2-10ms. When direct connection is not available, 20-100ms. In really bad network conditions with VPN's in use: 100-300ms. Though usually the latency is not really visible in the games even if there would be larger latency with some players :)
Love this! Will give it a try
Thanks! In case you'd like to give any feedback, there's a link to my Discord server on the footer of the frontpage :)
I shared this last month, but I’m still having a lot of fun working on it.
I made a daily word puzzle called Tiled Words.
https://tiledwords.com
Currently about 2,000 people play every day and I’ve released 59 puzzles!
One feature I’m excited about is crowdsourcing puzzles. Today’s puzzle is a “community puzzle” made entirely from clues that players submitted! I plan to do this every week or two.
I wrote about launching and the first month of puzzles if you want to learn more!
https://paulmakeswebsites.com/writing/a-month-of-tiled-words...
Thanks for this game, I've been playing it since you last posted it and it's become a regular in my morning brain wake-up routine of Minute Cryptic, Shuffalo at The New Yorker and a couple others, so I like the bite-size nature of it a lot.
Hey, that’s lovely to hear! I haven’t heard of Shuffalo. I’ll have to check that out!
I started playing a couple weeks ago (and got my Mum and one of her friends playing too).
I enjoy it, but I find the clues seem a bit too easy, and honestly I'm normally terrible at crosswords. Take that for what you will, totally understandable if you're aiming at "cozy/relaxing".
I appreciate the polish of the UI compared to a lot of the other janky word games out there anyway.
Hey, thanks for playing and sharing!
And thanks for the feedback! Balancing the puzzles is really tricky so it’s good to know when folks think it’s too easy or too hard.
It’s interesting to see the range of player skill (and how much they do or don’t enjoy challenge.) On a recent puzzle one player left feedback that it was too easy and another left feedback that it was too hard.
My aim is for puzzles to be challenging but not frustrating. The hard part is frustrating means different things to different people. From my stats I can see some players complete a puzzle in 2 minutes that takes another player 20.
For the daily puzzle I do lean towards making it a little easier but I want to explore a few ideas for making trickier puzzles in the future.
- Releasing additional “bonus” puzzles this are harder or more complex - Letting people build and share their own puzzles at whatever difficulty they choose - Adding settings to allow players to toggle things like hiding the theme at first.
That said, I’m still trying to figure out the overall balance for the daily puzzles! It’s good to know you think they’re a little on the easy side. I should try to gather more feedback and maybe tweak that!
I've been playing it with my wife of an evening. I like the difficulty level. It's nice to be able to solve it in under 5 minutes before bed.
Thanks! Yeah that’s the difficulty I’m mostly aiming for now.
That said, I’d love to offer packs of harder puzzles or user generated puzzles in the future!
I've been playing by just looking at the title of the puzzle and ignoring the clues. I can solve most of the puzzles that way, and it increases the challenge.
Yeah I’ve heard from a few people that they play this way! I’d like to add an official setting for it in the future
First time I see such a simple but attractive puzzle. I had to try to reproduce it using my Codorex tool, it's semi-functional needs a few more iterations:
https://codorex.com/shared/zIe6BrLCVfaPt1DuWm1DeyoMIIeTPyed
Congrats on the traction!
I'd love to learn how you grew your audience so fast! I built https://dailybaffle.com but haven't reached your numbers yet.
Have you submitted it to those daily -DLE games directories?
I submitted it to playlin.io
I noticed it was added to a couple of others that I didn't submit to (goldles.com and dles.aukspot.com) I'm not sure if there are others I should be aware of.
Daily Baffle looks nice!
I’m not totally sure! Marketing is not my strong suit.
I think my biggest advantages are:
- It’s sticky. A good percentage of players keep playing once they start
- Organic sharing. Lots of people have told me they shared it with friends and family. (I also built a “share” feature)
The pattern so far has been:
- I share it or someone else shares it somewhere.
- There’s a big spike of people trying it out.
- I get some new players.
- The player count stays roughly steady until it gets shared somewhere else that gains traction.
It was featured by Thinky Games. Sharing here got people interested. Someone shared it on Metafilter and that got a lot of views. Other folks have shared it on other sites that have led to smaller bumps.
But I’m still experimenting.
Thanks!
I'm not really a puzzle fan generally but that is absolutely brilliant!
Thanks!
Congrats, I liked your game and the level of polish you put into it.
Thanks!
My sister and I are glued to it, and she continues to destroy me, with consistent zero reveals and half the time to complete, as yours truly. We love this game. thanks.
Thats awesome haha, thanks!
My friend from work showed me this a couple of weeks ago, and now we all play it as a daily office ritual. Great game!
Hey, that’s awesome! If you’re comfortable sharing I’d be curious what industry you’re in!
My wife and I play this every day. It's the only fault word games that has ever caught my interest.
The UI is fantastic too.
Thanks! I’m glad you and your wife are enjoying it!
Just to let you know, my friend and I play this every day since I saw it here a little while back. Thank you!
That’s awesome, thank you!
I do a lot of word games (mostly crosswords.) This is great, congrats on launching!
Thanks, I’m glad you like it!
Have been enjoying it daily since I saw it on HN a few weeks ago. Great game!
That’s awesome, thanks!
I really enjoy tiled words, thanks for making this new addition to my daily routine!
Thanks for playing!
Really fun!
this is really nice, thanks for sharing!
Dude this rules!! Your animations are fantastic. Nice job and I'm really happy to hear you've got a consistent player base!
I also made a puzzle game in a similar vein slidecross.io
Thanks! Slide Cross is fun!
I love UI animations but they can be overkill for a lot of web UIs so it was fun to have a playground where I could lean into that more. (Though I still ended up pulling back from some of my more “out there” experiments haha)
This is such a fun game. Thank you.
Thanks!
This is really fun! Great work!
Thank you! I’m glad you enjoyed it!
I'm working on "Cargo but for C".
It started out as something marginally more useful than vendoring your dependencies as submodules + baking in the knowledge of how to build a bunch of common projects.
I realized, though, that there was somehow a huge gap in the insane world of C build tools. There's nothing that:
- Lets you pin really precisely and builds everything from source (i.e. no binary repository)
- Does not depend on either a scripting language or a completely insane DSL (Conan uses Python, CMake is an eldritch horror, ditto Make, lots of other tools of course but none of them quite hit the mark)
- Has a good balance of "builds are data" and "builds are code".
Anyway, it's going great. There are, of course, a ton of problems to solve. Chief among them is the obvious caveat that C is not a monoculture like Rust. There will be zero upstream libraries that use this tool natively. But I don't think it matters. I think I can build something which is as much better to the existing tools as, say, UV was to existing Python tools, even with that disadvantage.
Nice stuff! I'm keen to see this too.
I love programming in rust. Lots of non-rust developers think the whole point of rust is safety, but honestly, the things I like most about using it are the quality of life features like cargo. I love the idea of bringing that to C!
Relevant to this thread: I've spent the last week or so hand porting SeL4 from C to Rust, mostly so I can learn how it works (and learn OS development more generally). One of the biggest pain points I've had trying to use SeL4 is understanding the insanely complex way it uses cmake to compile the kernel and userland software. With Cargo, I can just run `cargo build` on my rust kernel project and it just works[1]. I don't even have a build.rs.
Anyway, I'd love it if we had a tool that made sel4 so easy to build. I doubt it'll be that simple, but its a lovely goal.
[1] (Well, except for one small step: You need to run objcopy to convert the 64 bit elf into a 32 bit elf to run it in qemu. But other than that!)
I’ll have a go at writing a package for sel4 as a delicious bowl of dog food.
Are you interested in the result? If so, just reply with some handle where I can reach you.
Sounds interesting and challenging. There's something similar, although not the build part just the modular aspect of it inspired by CPAN called CCAN: https://ccodearchive.net/. Very few people know about it, I believe, and it goes way back. I'm not involved with that project, though. Good luck!
Thanks for the link! I’ve never seen this one. I’m going to take a look through it.
Please post it here when it's ready! I'd absolutely be interested in seeing it.
Thanks for the encouragement! It really means a lot. Something should be out around the other side of the new year.
Good luck! Building the next uv is certainly ambitious, but I love ambitious projects :)
In my case, to a fault…
is it already in open source? I would like to see and test it. Share it here - on HN, when you will be ready
Yup! But not in any state to be linked, really. First impressions are a big deal. If you’re really curious, my GH handle is tspader and the repo is spn. The graph branch has been the main branch for a month or so, I need to merge badly.
Thanks, it looks promising! I built it and felt cargo-style - friendly and colorful. Look like you really know what you do and what C community wait from such tool. So, I leave my humble star on repo :). Good luck!
I've used Conan briefly in the past for C++ and I quite liked it.
Me too! It's pretty good. Unfortunately, it depend on Python. Not that Python's that bad. It's just that it's completely bonkers to me that building C, the most fundamental language that's commonly written today, the language that every other language has an FFI for and three quarters of them either are written in or were bootstrapped with a version written in -- that this language depends on PYTHON to build!
It's crazy, and I understand why it's the case, but I know how to fix it and I'd like to have a crack at it.
How is this different from bazel?
It’s about as related to Bazel as it is to, say, Maven. Bazel builds huge monorepos which use lots of languages. Not particularly related to C.
Bazel is used by many in the C/C++ world to build projects with dependencies fetched and built from source. It is not monorepo specific.
bazel is large and complex. aimed at a ton more languages, not just C

https://trivyn.io
Trivyn: Ontology-first knowledge platform. Runs on a single machine, via a single executable. I wanted a simpler alternative to the large complicated enterprise products that tend to dominate this space.
I'm really trying to get a private beta out the door by Christmas. I do plan to have a free version for academic/personal use.
Backend is written in Rust, uses oxigraph for its triple store.
https://plimsoll-line.app
I learned that ships have a "max load" line (or Plimsoll Line) https://en.wikipedia.org/wiki/Load_line_(watercraft) to prevent overloading them with cargos, but my todo list didn't. So I built an app to surface my emotional load and put mental health above raw productivity.
I am experimenting with the concept of giving each item in the iOS Reminders app an impact multiplier between -1.0 and +1.0 to assign them "weights". The net weight of the todo items should indicate my overall mood or emotional burden. If it doesn't maybe I have yet thought about what's making me feel good or bringing me down. The net weight is visually represented by the "water line" that rises the more into the negative the net weight becomes. I'm thinking of adding features to nudge me into addressing the rising water line.
And since I want to lower my own stress and anxiety using this app, there is no signup or subscription. No data collection other than the bare minimum to make the "tip jar" working through the App Store IAP, so no PII collection.
Do you think you'd find this approach to be helpful for managing your own anxiety level?
(Edited to add a bit more clarification)
Love the idea! I was thinking it would be great if it could include a toggle that's kind of like the emotional version of selecting reverse y-axis in games (i.e. you can either push the controller up to look up, or push the controller up to look down) - you can either have the app show you tasks as how you see them. You could either use a view that has the more effortful/urgent ones in red, which may grow over time the longer you take to do them OR the tasks that cause you more anxiety to have a high blue capacity the moment you plug in the task and it reduces over time the longer you take to get to it. I guess my idea has a factor of procrastination that comes into play with the anxiety.
Thank you so much for taking a look at Plimsoll Line and giving such a good feedback! The anxiety caused by procrastination is definitely real, my wife and I both feel the stress when we see our devices spew the same reminders that have been postponed for many days (or months!).
The main thing that I would like the app to do is to nudge me to take small actions of visually surfacing the emotional impact of the individual items (a todo item or just a thought in my head) rather than them filling up my head. So I would like to be the one driving the app than the app driving me like most todo apps do. I want the app to help me break myself out of being paralyzed with anxiety by taking small actions that are doable and maybe even pleasant. Hopefully that makes sense when users try it. :)
So I'll have to think hard about how to solve the problems you mentioned, they are excellent points. Having fewer configurations and encouraging the user to take control of their emotions through small actions as core principles means some limitations in features...
Anyway, right now the app lets you write a "Quick Journal" into the Notes field in the Reminders app. I have in mind the app encouraging user to break down the items causing lots of stress into sub-items so it becomes more manageable. Or suggesting contacting a trusted friend that the user has selected in configuration beforehand.
Suggestions welcome on how else I can nudge myself and other anxious users! :)
I’m working on a video game, purely for fun.
Here is a work in progress build:
https://muffinman-io.itch.io/space-deck-x
It is a combination of a shoot-em-up and deck building. You fly and shoot until you get to the boss, when you get your deck out to fight them.
That genre combination is definitely too ambitious, but I think it is fun to play and I’m enjoying making it.
I have a bunch of ideas how to combine the two parts better. But over the years, I’ve learned to control scope creep and actually ship pet projects.
Right now I’m in a middle of changing how enemy waves are spawned. After that I want to make a short tutorial and add two more bosses as well as more enemies.
If you end up playing it, please share your feedback I’ll be glad to hear it.
The game is made using Kaplay, a game dec library which brings me joy to use. I can best describe it as my friend described Pico-8: “easy things are easy”. But compared to Pico-8, Kaplay doesn’t have virtual console limitations and comes with a big library of components. Try it out, the community is small, but the library itself is really fun and easy to use.
EDIT: For context, this is about two weeks of work, in the evenings when my kid is asleep.
Nice game. But the stars in the background were confusing and hard to distinguish between them and projectiles. That got me killed way too many times.
Great art style, fun music.
I couldn't figure out the Boss fight with cards though. I run out of energy and so I assume my turn is over. But how do I end my turn?
A button guide in the main menu would be helpful.
I hear you, I have to add a tutorial.
- "z" plays a card - "x" ends your turn
If one never played deck builders, they probably have no idea what is going on. Thanks for trying it!
It's a fun little game. I didn't like that dying makes you start from level 1 though.
Congrats on your progress! This is pretty cool.
i wish i was that good at pixel art, it would be my sole hoby if i were
I completely understand what you mean, I often feel like that as well. Like every other skill, it takes time and it feels frightening when you see other people's work. Honestly I don't think I'm that good at pixel art, this is my first pixel art project. To be fair, spaceships and technology are pretty straight forward to draw.
Edit: typo
I’ve been working on a custom RTOS for Cortex-M for the past 10 years: https://github.com/raphui/rnk It started as a way to learn RTOS internals, and over time it has grown into something with lots of nice features. I’m even using it in a dirtbike anti-theft tracker I am building. Also, 2 months ago, I did a weekend challenge to build an embedded software parameter DSL and compiler. Its goal is to let firmware developers define configuration values, thresholds, constants, and other application-level parameters in a structured, human-readable format, and compile them into binary data that the firmware can directly use. https://github.com/raphui/epc
Happy to get any feedback :)
Had to read the wikipedia article on Real-Time Operating System (RTOS) to figure out what it was supposed to mean. https://en.wikipedia.org/wiki/Real-time_operating_system
They compare it to timeshare systems, which seems horribly out of date (although apparently that's still kind of what occurs anyways on CPUs). What's the part that's "Real Time" relative to anything else people do with Cortex processors? The preemptive part? Not trying to be critical, just not getting the real time part. Does it not share CPU resources among tasks? Get a fixed core per task or something? Minimal interrupts and minimal thread switching?
An RTOS compared to bare metal just means it is some nice abstractions that you would expect from an OS : tasks, mutexes rtc.
An RTOS compared to an OS like linux basically just means it is deterministic, you can guarantee some interrupt is handled within a certain time. Not necessarily faster
I want to build a complete radio station managed by an AI agent. It’s still at the idea stage right now: https://github.com/baturyilmaz/agent-radio
The idea is simple, but I think it could be really cool: an autonomous agent that actually manages an entire radio station. It creates its own shows, play copyright-free tracks, shares the daily program schedule on social media and the website, and later I want to add guest appearances too and live 7/24.
I'm actually building this exact thing right now. Using Gemini TTS with its multi-speaker capabilities. Soundtrack comes from a Suno Playlist which the tool will download the entire playlist at the start.
Plays 3-5 songs prior to a "break", where the logic will call out channel donators vs pick a random topic to discuss, then use an LLM to generate the script before sending to gemini.
In the end; its really just a wrapper around FFMPEG broadcasting to an SRT or RTMP stream. I can upload the latest branch when I get home to share
If you intersperse the music and fill in with articles from HN or your favorite subreddits it would be a fun listen.
that’s great to hear. I’d love to check out your project and have a chat if you’re up for it. maybe i can contribute to it instead of working on a separate project.
That sounds like a dystopia.
I am pretty sure 90% of playlists you hear when out and about are generated by spotify algorithms at this point. I would more be concerned because it seems like a weird use for LLM when recommendation engines are probably better than it? I suppose it has a ton of training data around music forums and people recommending songs, but it is hard to believe that would beat out billions of hours of tracked listening spotify has access too.
As bearish as I am on AI, outside of the agent deciding it only wants to play "Semi Charmed Life" and nothing else, I fail to see how this is a nightmarish hellscape in and of itself.
I feel standard commercial radio is already that hellscape. I mostly listen to rock (classic or alternative radio stations) and it's the same ~20 things being rinsed and repeated every hour and every day. Has been this way for decades.
I want to become a software professional, but I don't really know how I can do it. Focus on studying for many certificates or go to work or study at a higher level in school... Now AI is developing very fast; Claude can code very fast for every feature in my project, so I think I'm about to lose my job.

Yup, it's another task manager.
I made it for myself to help me focus on one task at a time, hence the name.
It implements my number one productivity hack of picking a task and setting a timer. Time spent on a task increments.
Data is stored locally in the browser although there is a sync option i wouldn't shake a stick at if I hadn't built this myself.
Plus it's a PWA! Those are lovely.
Just launched my gaming portal a few weeks ago, featuring over 200 games I've made over the years:
https://ookigame.com/
All the games were either developed with libGDX or threejs. I have no plan to monetize yet and still work on building traffic and improving SEO. Surprisingly, I got approved for google adsense already, which I submitted just for experimenting.
Congrats! 200 games IS A LOT.
I loved the 2000s vibes on the design too, so I appreciate it!
thanks a lot!
Working on a TUI tool which demonstrates the behaviour of X86 SIMD instructions. This is all done in Go assembly, and is probably most valuable for Go programmers.
The problem for me was trying to read and understand the implementation of a swiss map implementation. The SIMD instructions were challenging to understand and the documentation felt difficult to read. I thought that if I had an interactive tool where I could set the inputs to a SIMD instruction and then read the outputs, understanding the instructions would be much easier.
This turned out to be true.
Building this tool for all AVX/AVX2 instructions turned out to be a larger task than I had expected. Naively I just went off a Wikipedia page on AXV and assumed it had listed all the instructions (this was a bad assumption).
I am nearly there. Looking forward to completing this project so I can actually use it to do some fun stuff processing text and maybe even get back to that swiss map implementation.

(This is also my first attempt at a TUI app)
If anyone wants to try it out (the UI is a bit rough). I will try fix up any issues that are uncovered.
UI seems fine to me! It's easy to understand and use. A screenshot in the README would be nice.
I am working on a self-hostable borrow store management system: https://github.com/leihbase/leihbase.
I am running it in my city for a library of things. We hope to help people abstain from buying things they only need once a year.
It includes a reservation system, and an dashboard to manage those reservations in the shop. Currently I'm expanding it with a proper product management interface.
Probably work for a lot of normal libraries.
Here's a picture of the books we have and a couple of preview pages. You can put yourself on the reserve list. Tell you how long the current borrower, or the current "candidate for borrowing" has had the item, or had the possibility of borrowing.
What a wonderful project the Leihbar is! My local MakerSpace has something similar, but it’s pretty unofficial, you just have to announce what you’ve taken in a public chat.
I’ve often had the problem that I’ve needed a tool and borrowing it from Obi or similar cost more than half the price of a new one so I just bought a variant from Parkside for cheaper or similar price. Keep up the good work!
An interesting twist on this, would be to hold the used item while "paying" for it with a collateral. It would remove the need to have an owner to which the item must return to, allowing it to behave more like a linked list, reducing the amoutn of trips by two.
I also think that for taxeable purposes this would work better than buying and selling used items, especially in countries with gross income taxes. In the rest of the cases at least it would reduce the administrative burden to prove that ones net-income or value-add was marginal or negative.

Working on a new newsletter to encourage people get off social media by helping them discover all sorts of random interesting sites that exist out on the open web.
Subscribed. How do you promote your newsletter? Trying myself to build a newsletter and having challenges in getting subscribers.
I don’t promote it. I have a blog. I let people know about the things I do on there. And if those people like it they might write or post about it. It’s just word of mouth.
But I also don’t really care about growth. I’m not trying to build anything massive. I just want to be helpful to people.
Nice one Manuel!
Thank you. I'm quite tired to see people insisting that the web is dead or is dying while it clearly is not since there's a lot of great content out there. But it is getting harder and harder to come by, that's for sure an issue.
awesome work, subscribed!
Bedtime Bulb v2 [0], a light bulb that emits less blue light than other lighting, is finally shipping. It took years to get it right, but we figured out how to make a relatively energy efficient bulb that emits infrared and dims smoothly with any dimmer.
My team is also about to ship Atmos [1], a lamp for the bedside that automatically shifts from higher-blue light during the daytime to low blue light at night.
[0] https://restfullighting.com/bbv2
[1] https://restfullighting.com/atmos
How does the Bedtime Bulb compare to Philips' "warm glow" bulbs, which also adjust their color temperature as they dim?
Very cool, what’s the temperature range/wavelengths? (good idea to specify it on the product page - otherwise it’s unclear how is it different from other lightbulbs)
The bulb ranges from 1700K to 2100K (it warm dims)
Atmos ranges from 1800K to 5700K
Maybe not the most obvious, but for both products, it’s in the tech specs under Quality of Light. We try to be very detailed with what we publish there. Thanks!
Indeed there are very detailed specs on the bottom of the page!
It’s not obvious because I didn’t get there - I expected it to be one of the expanding sections with “Product Details” and so on. (I.e. when you have expanding sections to start with, it’s standard that all the information is the sections, and users are trained not to scroll down).
That's a great idea. I will add that! Thank you
very interesting. Can I control these with home assistant?
I already have a wind down dimming schedule on my entire home. It changes brightness and color temperature gradually over 2 hours. How do these bulbs compare with philips hue?
Yes, the bulb can be controlled with a smart dimmer like the Leviton model we sell on our site, or the Lutron Caseta plug-in dimmer.
These bulbs are not smart and do not have a full RGB array. But what you gain is way higher color quality even at low color temperature (1700K), much lower flicker, and infrared.
Atmos is a smart lamp, and we will get our Matter certification in early 2026. This one is also not RGB, but it has extremely high color quality in the whites and no blue spike. Flicker is lower and at a way higher frequency (32 kHz). We haven't updated the specs on the site yet as we are wrapping the calibration, but the CRI is 98 on the Atmos lamp.
The blue light “science” is a fallacy. I think N=8 in the original study and the difference in sleep was about 15 mins.
It’s a combination of factors: you must reduce both blue light and intensity of light to avoid suppressing melatonin. Just reducing blue light might help a little, but it still suppresses melatonin. Melatonin levels and circadian phase shifts scale with total irradiance even if blue-depleted; basically, dimming the lights is really effective.
That’s why our products focus on both intensity and color change (but we lead with blue light reduction since it’s easier to grasp).
Also, if you look at our specs, you’ll see that we don’t use pure amber or red light; we use very low-blue white light with high color rendering. We have yet to do the study on this, but you can read surprisingly well with our lighting at a very low intensity (enough to make your mom angry that you are hurting your eyes), whereas with lower CRI sources, you would have to make them brighter to achieve the same visual acuity.
There is some emerging research that IR may play a role in melatonin production locally in cells, which is why we added it to the bulb. Early days for this scientifically, but Scott Zimmerman and associated researchers suggest wideband IR may be effective, even if it’s only 20-30% of the visible intensity.
Oh very cool! Is the lamp being made in Canada?
Yes, for PCBA and final assembly!
This is amazing!
Thank you!
Is it possible for the bulb to gradually lose brightness as the night goes on? The default of a light bulb being as strong as 4am as it is at 1am is certainly simple, but does not make for a good nighttime experience.
With the Atmos lamp, yes! It constantly makes very minor, imperceptible changes every few seconds. I also developed an app, currently in public beta, for Philips Hue that does this as well [0].
We're working on a Nest-style ML feature for the Atmos lamp that learns your intensity preferences and automatically applies them. And we have a whole bunch smart circadian products we're working on—something for the desk and workspace next.
For Bedtime Bulb v2, not out-of-the-box because it's all analog electronics, but we REALLY want people to dim it gradually throughout the evening. If you want to automate dimming, the Leviton Smart Dimmer we offer on the site will allow you to control it with any of the popular smart home platforms.
Why isn't Bedtime Bulb smart? Bedtime Bulb v1 was our MVP, and we focused on getting the quality of light right over adding any smart features. It turns out, many of our customers have told us they don't want anything smart. So when we made v2, we focused on doubling down on quality of light features: infrared, warm dimming, "Perfect Dimming" (smooth dimming with any TRIAC or ELV dimmer), really high CRI/R9/TM-30, etc.
Smart bulbs are definitely a future possibility, but right now, we have the analog line (Bedtime Bulb v2) and smart line of fully-integrated lamps (Atmos).

I built a free USCIS form-filling tool (no Adobe required)
USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.
So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.
https://fillvisa.com/demo/
What Fillvisa does:
- Fill USCIS forms directly in your browser - no Adobe needed
- 100% free
- No login/account required
- Autosave as you type
- Local-only storage (your data never leaves the browser)
- Clean, mobile-friendly UI
- Generates the official USCIS PDF, ready to submit
- Built-in signature pad
I just wanted a fast, modern, free way to complete the actual USCIS form itself without the PDF headaches. This is a beta version
Feel like a Reddit bot, yet USCIS is "United States Customs and Immigration Services". The forms list that's probably of interest are found at:

I started a challenge I call “Dopamine Detox December” in which I stopped doing certain things to stop dopamine stimulants: - No social Media - No news - No video streaming services (such as YT, Netflix, and Amazon Prime) - No electronic and energetic music
The first days were so hard but now I’m getting used to it. I documented it here: https://ramezanpour.net/post/2025/12/11/dopamine-detox-is-ha...
you could probably fast-track this with meditation if you aren't already
I've heard so. I have done some basic types of meditations but I never had a chance to "properly" meditate, I would say.

https://meetlace.ai - LACE, a self-organising research companion for long-horizon inquiry.
With LLMs, generating ideas and snippets is cheap; what’s hard is keeping track of fragments with their “why I cared” context over months. Most tools (Notion/Obsidian/etc.) assume you will do the work (folder/tag/linking) structure will maintain it forever. I don’t.
In LACE we: – capture fragments from the web via a browser extension – auto-cluster them into evolving “threads” / projects with summaries & reading lists – maintain a graph of connections across threads (“topology of attention”) – let you turn a cluster of fragments into an essay draft when you’re ready to share.
Stack is a fairly standard web app + LLM pipeline. Used neo4j's llm-graph-builder as a starting point.
The interesting bit is self-organising graph. treating fragments/questions/lines of inquiry as first-class objects and letting the system reorganise around them over time instead of fixed folders.
It’s in a small test phase right now. If you’re a researcher/writer/engineer/founder who constantly loses good ideas in your notes and want to try something opinionated in this space, I’d love feedback.

This is brilliant. Love the UI too!
Thanks, appreciate it! The UI is still early so it’s great to hear it lands. curious what kind of stuff you’d imagine using it for most
Working on cargo like tooling for cpp. It just let you jump start a project for different build systems(vcpkg, bazel and meson). I am also planning to bring CLion features build on docker, ssh to cli with tui setup. Docker side is close to complete working on ssh for now.

I wanted to export long chats from Microsoft Teams but turns out Microsoft Graph API or some PowerShell scripts were necessary. API access is not enabled by our IT manager by default so existing solutions dis not help. So I built (vibe-coded) a browser extension for myself, then decided to open source it. There are still some edges to smooth out but it’s going fine.
Turns out it was a common pain point. Now it has around 800 users in Chrome+Firefox. Mostly chrome.

I'm working on Mutacortechs, an ALife simulation where "organisms" each have their own emulated 16-bit processor with 64K RAM. Like Core Wars for the 21st century. It's a small project compared to what some others here are working on, but it's an order of magnitude larger than anything this embedded EE has ever written. I have the ISA designed, assembler complete, emulator stage 1 complete (160/204 instructions implemented), and the start of the simulation working. Last night I wrote a program in custom assembly for an "organism" that looked around, found food, moved toward it, and ate it. I'm pretty excited by the milestone!
Any way to follow the progress of the project?
I’m learning git and it’s on a private GitHub, but since I’m not a “real” programmer, I’m a bit reticent to make it public.

ZenBot Stock Scanner https://www.zenscans.com One-man built and maintained stock scanner that finds stocks with relative strength to the market. It grew out of my early attempts to algo-trade stocks and has a solid community following. Front end is C#/Blazor, back end is a C# console app with intense parallel processing and data aggregation.
I’m self-teaching modern C++ by developing a native music library manager and player for Windows, macOS and other Unix systems. The main focus is on the 100% custom UI (with Direct2D/CoreGraphics/Cairo backends), aiming for responsiveness, power-user friendliness and compactness. The UI thread is absolutely sacred and I’m trying really hard to separate the core logic from the UI, because I hate how laggy and hang-prone all players I’ve tried are. I’m drawing inspiration from pre-2010 skeuomorphic and dense UIs. Key features include fast incremental imports and powerful UI elements with features like multiple column sorting, multiple element selection and keyboard-first navigation. I understand this problem is already solved, but I’m starting to DJ and curate my personal music library again. So far, nothing has been more satisfying than an old unsupported version of iTunes that doesn’t even support FLAC. I’ve tried foobar2000 but it doesn’t meet many of my requirements. Therefore, I’m building this software both because I have a need and because writing it is very fun (and frustrating at times)!
I’ve written a PoC already (mind the crappy and incomplete UI), mostly to test the wild custom UI idea, and it’s working so far! https://i.redd.it/ocx9m5av6d6g1.jpeg
The simplicity and density of that UI is nostalgic. You say it's crappy and incomplete, but all I'd want is a search bar which can actually scroll the whole-library view to the found-song (something I wish Spotify did, but they only filter.)
Okay fine, playlists are a good thing to have as well. Either way, I miss stuff this simple.
Implement them like the iPod used to implement playlists. There's no playlist bars, tabs, UI, or other clutter. You just had a default list you were working on, and anything you added got added to it.
Except for the constant glitching and crashing, the iPod had a really great user interface. (and to be fair, that was probably partially my fault for downloading all kinds of sketchy MP3s)

Lineage-aware. Versioned. Trustworthy Data - for Engineers and AI.
Your engineers waste up to 40% of their time monitoring, investigating and fixing data. Even then you don’t trust the accuracy, source, or freshness of metrics on your dashboard. You wish AI can answer your data questions but it cannot show you proof, or where it came from. AI helps software engineers to move fast and break things, because they can always rollback, with git. But you cannot do that for data. Bad data entering the system, spreads across the company before spotting, and takes weeks to clean up.
DV changes this, giving you lineage-aware, versioned data. It records data-lineage when data is captured, transformed, and committed, at commit/snapshot level. So when things break, DV knows what other data is impacted downstream, and it can rollback the whole chain to the previous state, instantly - no data copy/restore needed. It can also backfill the data across the chain automatically.
With DV, both your team and your AI agents can finally see: - where data came from - how it was transformed - how to revert safely with a single click
Your engineers can move fast on data, without breaking trust. Your analysts can build pipelines by simply describing business questions to AI.
DV is Git for data, so you can focus on your business, putting analytics on auto pilot.

Want to put local history on a map, so when I go somewhere I could ideally just open this webapp and immediately get presented with cool or interesting history that happened close by.
Currently spending time establishing relationships with historical societies, as I really need them to contribute points of interest, and stories. Many of these societies are run on a voluntary basis by 70+ year olds, so it's a long process. Getting some good responses eventually though, so it might actually go somewhere, just a lot slower than I want.
Also still doing https://wheretodrink.beer, but haven't added anything of note since playing on this other project.
And react2shell was a blast
What’s the name of your localized history app? I’d love to contribute for my little town.
Oh, thanks for the interest, but I'm not that far along yet. I have a bare bones alpha, but it's not ready for the internet just yet. I also haven't secured the domain names so I won't be sharing any code names :)
This is so very silly, but the only way I have to collect emails for people interested in the progress, beta testing or final version, is on my beer page.. So I created a page for the world's most obscure / smallest city and if you want to be updated you can register there - https://wheretodrink.beer/in/croatia/hum-75gkn - The registration is under "Stay informed about updates in Hum?"
If anyone signs up I'll manually move you out of that list and into the "local history" waitlist.
I'm working on a postcard maker for museum collection artworks in the creative commons. It's in a phase where I'm looking to get feedback from people who might like to use it.

Still very early stages, just put the site together a few days ago: Veform https://veform.co/
iOS/JS/Android Libraries for turning traditional inputs/forms into audio conversations.
Have everything working and am happy with how the underlying data structures came out.
It is interesting because where I ultimately landed there is just an additional "state". So there is a UI state (Browser managed DOM), your app logic state (consumers manage), and a conversation state. The library just exposes events so you can keep the conversation state in sync with your other states. I started out visualizing a direct like: <form/> as a conversation flow, but you could configure it to navigate pages, click elements, or whatever through audio conversation.
I'm working on an affordable SaaS platform for small and mid-sized fabrication shops across the US and Canada. It automates quoting and production for sheet-metal and CNC jobs and can handle pretty much any CAD format, even full assemblies. On the AI side, we've got a mix of models doing the heavy lifting: a tuned geometric transformer for feature detection, a graph neural net for topology, and a vision model for mesh segmentation. All that ties into our custom CAD logic for geometry parsing, 2D nesting for laser/machining, and 3D nesting for forming and packaging. The whole idea is to level the playing field so smaller local shops can compete with the big instant-quote guys without needing an in-house dev team.
Is is essentially a SaaS version of what businesses like OSH Cut and SendCutSend have built? And are you doing just the quoting, or full shop management?
That's exactly what it is. But instead of keeping it as some proprietary tool for one shop, our goal is to make that same tech accessible and affordable for all shops. Not every fab shop is tech-first, and that's totally fine. We're building something that helps them compete without needing a full-time developer or a six-figure software budget.
As for your last question, we're not trying to replace any existing ERP or CRM systems. We're focused on delivering instant, accurate quotations through our own turnkey pricing model that helps job shops stay competitive day-to-day, manage payments seamlessly, and give customers real-time shipping options or an easy Will Call pickup if they're local.
I can't tell how you allow the small shops to make instant-quotes. Is it because they can instantly visualize the part? Or do you process the customer's design and provide the shop additional information that helps them do this? Or are you just generating the final quote itself already based on what you know about the shop and the customer design?
Good question! Right now we’re starting with the sheet metal side of things: laser cutting, forming, welding, surface finishing, and final touches like anodizing, powder coat, or just a clean mill finish. The platform takes the customer’s CAD file, runs DFM checks, figures out material usage, laser time, bend complexity, and weld length, then instantly generates a production-ready quote based on each shop’s own pricing and capabilities. This quote includes delivery cost + an estimated time you can expect the part. There’s 2D and 3D visualization built in, but the real magic is the drag-and-drop, get-an-instant-quote experience. The reality is, most fab shops are still painfully slow when it comes to quoting. Even in 2025 it’s not unusual to wait a week (or three) just to hear back. That’s the gap we’re closing.
Very interesting. The big followup question is to ask is: Currently shops spend X% of their time creating quotes and talking to incoming customers, and (100-X)% time actually doing the work. What is X% for a typical shop and how much are you hoping to reduce it to?
Based on industry data and first-hand experience, most small to mid-sized fabrication shops spend 25–40% of their total time on quoting-related activities: reviewing customer drawings, clarifying requirements, preparing cost breakdowns, and going back and forth over email or phone. In some job shops with limited staff, quoting can even eat up half a workweek for the owner or lead estimator.
Our goal is to bring that number down to under 5% by automating geometry analysis, material costing, and lead-time estimation. Essentially turning what used to take days (or weeks) into an instant, self-service process for customers. That frees up the shop to spend the remaining 95%+ of their time doing what actually makes money: fabricating parts.
For reference: https://www.reddit.com/r/AskEngineers/comments/n1yryi/mfg_qu...
This sounds interesting. Are you using any CAD software for this? Can the fabricator create their own design?
No, we aren’t using any CAD software for this since we’re not trying to be in the design space ourselves. Instead, we’re using libraries like OpenCascade’s Mesh Toolkit to read and tessellate CAD files into a hybrid 3D format optimized for web rendering, while preserving precise geometry, topology, and manufacturing data.

Making a first aid kit for stingray stings! If there are lifeguards nearby they’ll usually treat you, but we think it would be nice to have a “go bag” in the back of your car for scenarios where there aren’t lifeguards (remote beaches, or after sunset, etc). The standard of care is to clean the wound and submerge it in water around 110-120F for 1-2 hours. We’ve been researching the best, safest method to get that heat, and working on putting a package together. Here’s our first attempt:
https://mydragonskin.com/products/stingray-treatment-kit
okay, easiest branding ever: “quick! go fetch The Irwin!”
IRWN — Immersion, Rinse, Warm, Notify
Should only cost them a billion dollars.
I actually doubt that. Irwin was a philanthropist and a scientist, with a decent sense of humor. This is a basically profitless project for public good. I think if the founder has bona-fides, Irwin’s estate would jump at it.
Hmmm we've never approached the Irwin estate, even though all our work is about stingray sting prevention and treatment. We do need to make profit to stay in business, so it's not entirely charity. Maybe we should see how they feel though. I also worry about the optics of advertising so directly on somebody's death. Especially because none of our products would have prevented / helped in his scenario.
Anyways, it's a good idea, thanks for the push!
I hope you’re right!
As a backup, The Stinger or The Sting-Ray should also do well!
Sting-ER could also work too

A personal photography website for myself using a bunch of AI services to enable automatic tagging, color extraction, and hopefully some novel discovery methods.
I really like the color discovery features - I wanted something like this to exist when I was trying to find prints for my house with specific color harmonies.
I just moved to a house with a barely finished basement. White walls, white painted floor, exposed ceiling joists and ductwork painted black. I’m experimenting with cheap projectors and lighting effects (using clamps to attach to the joists as if they were a truss) and furniture on wheels to create a configurable virtual space with full wall projections, sound, and lighting to match (but not overpower) the video. My plan is to make a camera/light platform with a cheap projector, and Raspberry Pi, and directional LED lighting so that I can coordinate all of them over the network. It’s also my office, library, game room and I have some awesome ideas on how to use the space to augment D&D games. But the white concrete floor has got to go - too bright, too cold, too hard, and too loud.

I'm working on a Unicode visualization tool [note 1]. It's meant to visualize transformations and relationships between characters, as well as connect everything directly to the exact lines in the Unicode Character Database (UCD), which defines these relationships. The UCD is a series of text files, it also has an XML version.
I love online Unicode tools, serious ones and silly ones, and I use them often for fun or for development. What I see online is that few technical people have a good understanding of Unicode, or have big misconceptions about how it works. I'd like to change that, through visualizations and direct links to the data sources (the aforementioned UCD) and links to the Unicode documentation (which is well-written but can be difficult to navigate or even find).
I've worked a lot on it, but I'm totally stuck again. I get too zoomed in and it's hard to see the big picture, plus it's difficult to know how much effort I can realistically put in because I don't know how big the market is. It's a niche tool, but how niche? Would anyone pay for it? But I'm not sure how to do market research, especially for a niche like this. Any advice would be appreciated!
1. The initial idea was based on this post I made in 2024: https://news.ycombinator.com/item?id=42014045
I'm interested, not to pay for it though. I'm curious about the visualization. Is there anywhere we can find screenshots or follow for updates?
I'm writing a toy eigenvalue solver in Rust using the QR algorithm. I didn't intend to, but I recently discovered the Gershgorin Circle Theorem and thought it'd be neat to create an interactive visualisation for my [blog](https://abstractnonsense.xyz).
I don't like JavaScript, and I've been meaning to learn Rust for a while, so I'm compiling the Rust algorithm to WebAssembly to run in the browser natively! It's been a fun trip back into the arcane world of numerical algorithms and linear algebra!
In my free time this year I've been working on a full stack JS framework called Torpor: https://torpor.dev (https://github.com/andrewjk/torpor)
Components are JS functions, containing UI that is (mostly) HTML, with reactivity only via proxied objects.
To test it out I built a distributed social media/microblog site called Redraft: https://redraft.social (https://github.com/andrewjk/redraft)
It's edge native (with a Cloudflare deploy button in that repo) with your posts stored in an SQLite file. You can log in to your site to post and comment on your own posts, and use a web extension to comment on posts from people you follow wherever they are on the web.
There are many bugs and missing features, the documentation is patchy, and it's probably riddled with security holes. Give it a go if you're feeling brave!
Looks pretty cool. I see some similarities with Mint language https://mint-lang.com/
I'm currently making a number of "breadboard-able" analog computing modules.
I've always loved electronics since I was a kid (still trying to learn). As I explore and learn I've begun to make these small "breadboard helpers" [1]. (Just one on Resistor Transistor Logic (RTL) right now.)
An obsession over a project in a 1970's hobbyist electronics magazine sent me down the rabbit hole that is (was) analog computing. So I have been bread-boarding and prototyping small analog computer modules.
I'm in the PCB-layout stage for the modules and hope to have them ready early next year.

I've been slowly building a website full of daily puzzle games (https://regularly.co/). I built the first game for my wife (https://regularly.co/countable) which she plays every day. Floored is my personal favourite, I find it deceptively challenging
How much code do you reuse between games? I'm looking for a "framework" to build multiple games writing only the game specific logic
What a wonderful and simple style. The games remind me on the games from linkedin, just without the dark pattern around it :)
Is there any way (e.g. paid subscription) to have access to all of the puzzles (all past history)? E.g. I'd love to be able to play all the past Kingly puzzles.
Sadly not at the moment but it was always the plan to eventually allow playing of the catalogue - I'm still unsure as to whether I'd choose the subscription model.
Thanks! I enjoyed floored, it reminds me of spelltower by zach gage which I also liked.
Thanks for pointing me to this - I love the UI. It's a real shame its only on mobile
I love Kingly. I've been playing it everyday.

This is actually pretty much as done as it's going to be (could use some nicer UI feedback, i.e. how you actually use the app) - it is actually just a demo for an effort I undertook to mod Datastar to support nested web components. I am writing it up as we speak!
Instructions: you have to answer three questions; each one will auto-submit once your response goes over 100 characters; the answer to the third question is your "post". It's a proof of concept of a friction intervention for social media to encourage slow thinking before posting (and hopefully reframing negative experiences in the mind, it's kind of dual purpose).
I’m working on a deterministic execution layer for AI systems.
The idea is to treat LLMs as constrained components inside explicitly defined workflows: strict input/output schemas, validated DAGs, clear failure modes, and replayable execution. Most “AI unreliability” I’ve seen isn’t model-related — it comes from ambiguous structure and hidden assumptions around the model.
We’re exploring this through a project called FACET, focused on making AI behavior testable, debuggable, and reproducible in the same way we expect from other parts of a system.
Still early, but the goal is simple: less magic, more contracts.
Purposefully not building software but cold calling 100 businesses in my niche. Starting at 1 call per day for 10 days, then 2 calls per day for 10 days, then 2 conversations per day for 10 days, and scaling up until I reach 100 calls. Exposure therapy as well as product discovery wrapped in one.
Calling them and asking for what exactly?
S&P 500 correlation matrix (created with Svelte).
Currently trying to better contextualize the visible subregion of the matrix in relation to the full dataset (beyond what the current minimap does).

Very nice aesthetic! You might enjoy affinity propagation also. [0]

Thank you for the feedback and your suggestion! A (partial) correlation network with Cytoscape.js is planned as one of my next experiments. A former colleague nudged me in that direction just a few days ago, and now you as well, so I'll probably have to build that next.
Building pyreqwest, a high-performance Python HTTP client backed by Rust’s reqwest. It has gotten quite feature rich: async and sync APIs, similar ergonomic interface of reqwest, full type hints, and built-in testing/mocking. It has no unsafe code, and no Python-side dependencies. (Started after getting too annoyed with all the issues httpx has.)
https://github.com/MarkusSintonen/pyreqwest
I've recently updated an internal tool which basically acts as a configuration and dependency/context manager for performing hundreds of api calls. I added an httpx backend (to test vs the current urllib3 backend) and also introduced an async API (httpx as well). However, from your benchmarks it seems like I should've went with aiohttp for faster async? I will work on integrating pyreqwest as well
Yes httpx is badly broken. Eg its connection pooling implementation is not great at all. There are various issues in httpx/httpcore. There are also old open PRs trying to fix issues but maintainer(s) are just not intrested.
Good to know, will be interesting when we run our tests. Thanks for the info and for your work on pyreqwest, looks very promising
That sounds awesome. But I have two curiosities: What are the problems of httpx? And was pycurl not enough for what you wanted to do?
Httpx/httpcore are abandoned and their connection pooling etc implementations are completely broken https://github.com/encode/httpx/issues/3215 Many PRs trying to fix varying issues https://github.com/encode/httpcore/pulls But maintainer(s) are not intrested in fixing any of the issues.
pycurl doesnt support async, right?
Working on NetBox Designs: https://netboxlabs.com/blog/netbox-designs-introducing-decla...
Infrastructure architects think in terms of building blocks in "high-level designs" and those building blocks are often socialised/expressed in Visio/Spreadsheets. Thinking in building blocks is now more necessary than ever because of the sheer size of the infra being designed/deployed.
This approach is problematic after the design phase because there's a lossy translation to where the low-level design lives, often referred to as the Source of Truth, like NetBox.
NetBox Designs allows users to express composable, versioned, and templatizable building blocks that can be rendered to low level designs. No lossy translations, and you can always check in the future "does my LLD still match my HLD and if not, where?"
I've been building Hypertrophy, an iOS-native workout app. I've always wanted a simpler, cleaner experience than Strong (on which I've done over 1000 workouts) so I built my own.
I've tried to make it look and feel at home in iOS and I like to think of it as a Notes app for the gym—it does very few things and does them well.
It's completely free with no ads because I'm not a fan of how other workout apps charge you for a basic workout experience.
I've just finished up the Import from Strong feature and would love any feedback on it!
https://apps.apple.com/au/app/hypertrophy-gym-workout-log/id...
Love this! Been pondering building my own bloat-free one for a while, but this meets all my needs.
I’m kicking off my 2026 book club! It’s probably a bit different from book clubs you’re familiar with.
Each of us is reading sixty books over 2026, five a month, where every book is self selected by each member.
It’s small, six people, all brought in by application only.
You can check out our shared bookshelf here! (Heavy inspiration from Stripe Press)

1. Vibe coding a microcontroller firmware project. I'm using "vibe coding" in jest here because I'm actually an experienced coder, but this was a chance to try using the AI coding assistants for a clean sheet project at minimal risk. I'm going on 63, and could easily finish my career without AI, but where's the fun in that?
One amusing thing I've noticed is that every time the AI generates code with a hard coded hexadecimal constant, it's a hallucination. My son suggested feeding all of the chip datasheets into the AI and see if the constants improve.
2. Finally converting my home semi-hobby electronics business (something like a guitar effects pedal) to machine assembled circuit boards.
I was thinking about FizzBuzz and thought it might be cool to benchmark various LLMs to see the highest number they could go before they got it wrong. FizzBuzz is cool because you can test whether the model's can generalize to any other game (divisors of 3 and 7 instead of 3 and 5 for example).
Fun, short and sweet experiment to run over the weekend, with some mildly interesting results :)

I’m building PaperDrop it's a research workspace that turns PDFs and new arXiv papers into something you can actually work with (notes, questions, cross paper comparisons). Would love feedback from people who read a lot of papers: https://paperdrop.xyz
It's still early prototype / beta, but wanted to share it anyway!
i love this, thank you!
I have just released a map of median rents in Berlin [0]. Now I'm improving it. I want people to enter their search criteria, and get an idea of how rare and expensive their desired apartment would be.
This will help people set clear expectations for their apartment search.
[0]: https://allaboutberlin.com/tools/rent-map
Is this only data for new rental contracts and doesn’t reflect data from older/existing contracts?
The prices match ImmoScout, but are insanely high above the Mietspiegel, and therefore not actually a legal rent.
Where do you get the rent data from?
Map says "data from https://www.homeboy.immo/en" - maybe he scraped, just guessing.
Nice site, has tons of info on moving to Berlin. Must have time quite a bit of effort to put together
They scraped the info. I politely asked them for it. Otherwise I would need to maintain my own bots on top of everything else.
I'm working on EACL: http://github.com/theronic/eacl
EACL (Enterprise Access ControL) is a situated ReBAC authorization library based on SpiceDB, built in Clojure and backed by Datomic. EACL queries offer sub-millisecond query times and has replaced SpiceDB at work (CloudAfrica).
'Situated' here means that your permissions live _next_ to your data in Datomic, which avoids a network hop and avoids syncing to an external AuthZ system like SpiceDB, so all queries are fully consistent.
EACL is fast for typical workloads and is benchmarked against 800k permissioned entities. Once you need more scale or consistency semantics, you can sync your relationships from Datomic to SpiceDB 1-for-1 in near real-time because there is no impedance mismatch between EACL & SpiceDB.
Read the rationale for EACL here: https://eacl.dev/#why-was-eacl-built-the-problem-with-extern...
IMO, if you need fine-grained permissions, EACL is currently best-in-class for the Clojure ecosystem. EACL is especially suited to Electric Clojure applications and can be used to populate menus in real-time.
EACL would not have been possible to build solo in my spare time without modern AI models to rapidly implement specifications and test against human-written tests.
Here is a ~7-minute screen recording of EACL used from an Electric Clojure application for real-time ReBAC queries: https://x.com/PetrusTheron/status/1996344248925294773
Simplification of my digital self. Removed most of my online accounts. Removed all my VPS's. Removed most apps from my phone except core ones. Cancelled a lot of online subscriptions.
In the real world finally moved everything to USB-C. Gave all my old cables away. I have two chargers in my home and a handful of C to C cables. Everything connects to everything now.
Home is now downgraded to a dumb home. Lights work on physical toggles. No hubs or sensors anywhere. Heat and AC is with a dumb panel on the wall.
It feels freeing.
I did a similar thing a few years back, but rather than simplifying, I focused on getting rid of hacky DIY things that needed maintenance.
I got rid of almost all the customized software in my life, and the few projects I decided to keep, I aggressively modernized, getting rid of thousands of lines of original code and adding many times more tests than I'd ever had before.
It very significantly improved my life and career to not have a second part time job maintaining a note taking app.
How did you replace the customized software you had before?
With off the shelf options, preferring FOSS if possible, I still enjoy using and contributing to open source.
Some of the substitutions wound up being a step down in features, or required rethinking parts of workflows, but the time savings is such a benefit.
Custom notetaking tool with p2p sync-> Google keep
Custom batteries included Linux distro for SD protection, Kiosk browsers, offline docs, creative commons content packs -> a few scripts built into my control server on vanilla RasPi OS
Rsync-> Borg -> Kopia(to avoid fussing with Borg's community NAS package)
Portland, OR's Free Geek is a great place to donate old parts to. Every city should have a similar resource.
It was a lot of micro-USB and some Lightning. CAT5E and lower. HDMI 1.4 and lower. All still useable cables for many people. It went to my local hackerspace.
For me, it’s always having website productivity blockers on all my browsers across all my various devices (and for the most part, not installing news apps on any devices either). Haven’t simplified my digital life, but at least it’s very restricted. Yeah, if even one device doesn’t have one installed, feel like am vulnerable to having hours sucked away.
And actually, still browse the web and watch YouTube, but just on my non-work days.
I have asked ChatGPT recently how to de-optimize my life. It seems I'm not the only one who wants go back to the old ways of doing things :)
The GP not de-optimizing, just simplying life which is always a good thing.
I’m pretty sure step one to going back to “the old way” is not to ask ChatGPT
I maintain a list of things I have done here: https://nicolasbouliane.com/blog/silence
I love the design and content. Keep writing Nicolas
> Removed all my VPS's.
Do you still host things? If so, do you host from home and how?
I had a lot of hobby projects. Some home automation. Some would scrape websites for archival purposes. Maybe a seedbox and an arr-stack. Total monthly cost of a bit over €60 for all of them. Didn't really add anything to my life and the upkeep took about an hour every month, even with auto-updating as much as possible, sometimes things broke or required manual updating (+migration).
None of them were open to the public, I SSH-tunnel into them. All stuff just for myself.
I backed everything up locally and shut them down. They should be auto-removed at the next billing cycle.
No mention of tube amplifiers. Fail.
How do you pay taxes?
I use money.
I don't get how this relates to the post you are replying to?
https://pistepal.app/ - a ski map app - built at breakneck speed over the last few months. I believe this is the only ski map app that offers turn-by-turn navigation!
Screenshots in the App Stores, e.g. https://apps.apple.com/us/app/pistepal/id6754510927
Still a little bit rough around the edges but hopefully will be / is in decent enough shape for the start of the ski season (just about happening now..)
Currently figuring out the right balance of free tier & daily trial. Priced at $10/month and therefore significantly undercutting the competition, hopefully this is enough to gain entry into the market. (May need a more generous daily trial though, admittedly 10 minutes is not really enough to actually try it out on the mountain).
Seems ad spend is necessary to get any kind of traction...
Feedback welcome!
Add a “are my pals above or below me on this mountain” function (that doesn’t ruin my phone battery) and I’ll part with hard cash for this.
Specifically above or below? Or you're after "give me directions to my pals".. what's the use-case for above/below?
Yeah very specifically above or below. You don’t need to share exact location data (although you’d still need access to it on the local device) - just elevation.
Don’t over engineer it - just an indicator about how much further down the slope or back up the slope the rest of the pack is.
I find it annoyingly frequent that I’m either waiting for mates who have bombed off ahead because I didnt see them pass, or I’m waiting at the bottom for mates who are up the slope waiting for me because they think I’m behind ! Literally hours wasted each trip doing this.
You might think a quick phone call is the solution to this but that’s too clunky. It’d be nice to take out my phone and just quickly see something on the home screen indicating this, or on the watch app.
Would also think about ways in which the app could indicate the elevation of others without having to stop, remove the gloves, picking the phone from my pocket, looking at the screen, and putting everything back on every time.
Maybe having different kinds of (infrequent) beeping in specific cases: - when I'm last - when I'm first
This could get old quite quickly thought, just a thought.
That's a great idea. A lock screen widget could work really well here, showing the relative elevations of your buddies. You'd have to take your phone out - but you wouldn't have to take your gloves off!
So you can know if you’re waiting or catching up
I’m building a planner that automatically plans employee shift schedules based on their availabilities and roles.
There’s many different solutions out there but I’m carving out a niche where we deal with complex shift assignment problems.
For example one of our customers has specific union rules that need to be followed when assigning work and we ensure that they are compliant.
Our backend relies on an MIP solver as well as heuristic search to refine plans.
Open source Nerf blaster simulator, for both spring and pneumatic blasters.
https://github.com/btrettel/blastersim
The core simulator part works, but I don't yet have a user interface or documentation. Probably just going to be text input files to start, maybe a GUI later. Recently, I'm mostly working on testing.
The simulator is object-oriented and basically allows one to build up a blaster from separate control volumes and connections between control volumes. This is useful as it allows the same core simulator framework to handle different blaster configurations and even variants of them. For example, someone asked me to make the spring piston able to pull a vacuum on its back side due to not having sufficient flow. That's easy here as I just need to add another control volume and the appropriate connection onto the basic springer configuration.
Some months ago, I saw a tweet from @awilkinson: “I just found out how much we pay for DocuSign and my jaw dropped. What's the best alternative?” Me being naive, I thought “how hard could would it actually be to build a free e-sign tool?”
Turns out not that hard.
In about a weekend, I built a UETA and ESIGN compliant tool. And it was free. And it cost me less than $50. Unlimited free e-sign. https://useinkless.com/
What's UETA and ESIGN? What's preventing you from just drawing your signature on top of a PDF?
If the tool doesn't adhere to those standards, the resulting signature isn't legally compliant (at least, not in a way that satisfies corporate structures).
What does legally compliant even mean here? I can print a document, scribble on it with a pen, and scan it and that's legal, so how high can the digital bar be?

Trying to build a small-scale ISP/hosting provider domiciled in Canada. We really want to be able to rent real rack space to enthusiasts who would like to benefit from having stuff in the datacenter but don't want to take on the opportunity cost to get started. It came out of my own desire to have a machine in a DC rack.
This week we've been writing a bunch of "reviews" of self-hostable software since a lot of our friends are curious about this space but don't have a good understanding of how to get started. https://blog.colocataires.dev.
Your VMs are a bit pricier than some other larger services located in other parts of the world - which I understand. I hope you are able to scale to the point where you can lower these prices.
Are there any legal or other reasons I, a resident of Canada, should host my services in Canada rather than in Europe or US?
I'm currently working on something that lets you describe a hardware product in plain English and get actual manufacturable files out — PCB, enclosure, firmware, the lot.
Very early days still. Whilst I created a fork of toon for Kicad (called TOKN (https://www.mikeayles.com/#tokn)), with the intention of using a reduced token format to generate schematics using LLM's, I could get the models to follow the syntax correctly, but they didn't have the knowledge. So I was then going to create a whole RAG system, but got distracted by this current project.
There are people out there doing AI schematic generation, like flux.ai (which is incredible (and incredibly well funded)), but 90% of products, especially at proof of concept stage, are basically a microcontroller, some power, probably usb, and some IO, bluetooth/wifi if you're lucky. So we can use a library of pre-validated subcircuits and slots them together on a grid. Routing's deterministic, so if it compiles, it works. (sorry, deeppcb & Quilter!)
The enclosure side is more fun: once the PCB's done you've got real dimensions to work with (board size, mounting holes, where the connectors poke out), so I use an image model to generate some concept art, then feed that to an openscad generating model as visual inspiration alongside the hard constraints.
Basically trying to get a full hardware product pipeline done automatically.
Building a simple service that allows one to post live activities to mobile devices (iOS to begin with).
It started as something I wanted to build for myself. I have a Bosch dishwasher that lacks any glanceable indication of how far along it is. Bosch provides an app, but checking the progress takes too long to be useful.
I figured live activities was a good fit, and then realized that I am not alone in wanting something like this. So, I am trying to make it into something usable for all the home automation tinkerers.

I am still plugging away at https://threeemojis.com/en-US/play/hex/en-US/today , a daily word game for language learners.
Since hacker news last saw it, it’s been translated into English, German, Spanish and Chinese. If, say, a Chinese speaker wanted to learn more English words, then they could go to https://threeemojis.com/zh-CN/play/hex/en-US/today and play the game with English words with Chinese definitions and interface. This is the first cross language daily word game of its kind (as far as I know), so it’s been a lot of fun watching who plays which languages from where.
The next challenge that I’m thinking about is growing the game. The write ups and mentions on blogs add up, the social sharing helps, but I’d really like to break into the short form video realm.
If you read interviews from other word game creators, every successful game has some variation of got popular riding the wordle wave, or one random guy made a random TikTok one time that went super viral, and otherwise every other growth method they have tried since then hasn’t worked that well and they are coasting along.
So, sans another wordle wave, I am working on growing a TikTok following and then working on converting that following into players, a bit of a two step there, but that’s how the game is played these days. https://www.tiktok.com/@three_emojis_hq for the curious. Still experimenting and finding video styles and formats that travel well there. Pingo AI and other language apps have shown how strong TikTok can be for growth, so I think there’s something there. That’s all for this month!

Just launched a restricted browser for kids for iOS: https://weblock.online Now testing on my kids. The idea is that the browser is whitelist-only, so kids can open only approved websites. I receive a notification when they want to visit an unknown website and I can allow or deny it. Works great for my family, hope it will be useful for someone else.
How does it work on a more technical level? I would be interested in seeing a bit more tech detail, perhaps because I'm more technical, but also there's so much competition in this space that you need something to differentiate.
For example, is the blocklist UX side Domain based? Company based (Allow all by Google/Alphabet), category based (Search engines)?
And on the backend, is it DNS based or HTTP based? Or maybe an OS hook.
Hey, more technical details follow.
Weblock uses a whitelist, not a blacklist, and it is domain based. Once you allow a domain, it can be browsed by a child. You can allow it forever/15 minutes/1 hour.
How it works: WKWebView, before loading a page, asks the backend if the domain is allowed. If not, it shows "Not allowed" screen and a "Request access" button - child can tap it and you (parent) will get a notification.
So traffic is not going through the backend or a filtering VPN, the app just asks the backend if a page (domain) is allowed to visit.
Visits are logged, so you, as a parent, can see what your child has been browsing. How much time did he spend on a homework website.
Some WKWebView callbacks used for that: * onShouldStartLoadWithRequest - to intercept a request and check if it's allowed * onLoadProgress - to show loading progress bar * onNavigationStateChange - to track browsing history
Also I had to implement a workaround for buggy Screen Time in iOS 26 - even if you add Weblock to "always allowed" apps, iOS will still treat each website as a separate "app" and block it, asking to you "allow' each website on system level. It happens inside WebKit codebase, but luckily this bug has another bug in it - if you re-open a website, it suddenly works and all other websites in this session work tooSo I need to listen to `onScreenTimeBlockingStateChange` event and automatically reload a website if that happens.
Also I added an ad blocker to Weblock. It uses uBlock Origin filters, converts them to WKWebView content rule JSON format and feeds to WKWebView. The app checks the backend if rules are updated and updates a local copy.
What's next: need to get "Default Browser" entitlement from Apple. Then you can block Safari on kid's phone using Screen Time and have Weblock open all HTTP(S) URLs.
App is written in React Native, no performance issues. Backend is Ruby on Rails.
I’m building something that keeps finding gaps I didn’t realize were gaps.
It’s called Riftur, a gap analysis tool that compares two documents and highlights gaps, missing requirements, and inconsistencies. The interesting part for us has been getting the system to understand intent instead of just keywords, so it can flag partial matches and subtle gaps rather than just “present / not present.”
Still early, but it’s been useful in ways we didn’t fully expect. If anyone’s curious, you can demo it out here: https://riftur.com I'm happy to hear thoughts or learn how others handle this kind of review work.

For the past week, I’m working on creating device with a screen to show my indian parents if i’m in a meeting or not. So they don’t trouble me and come in my room unannounced when im in a meeting.
It’s build using ESP32 and a small screen which shows On and Off and the time till meeting is over. I learnt Fusion 360 and designed a small snap fit case and got it 3d printed.
I have a small electron app running in my mac os system tray which connect to esp using BLE and it also checks if Mac Camera is in use (using Apple logs) and then communicate it with the device.
Calling it Door Frame. Had quite fun making it as i learnt 3d design, c++ code using Platform IO and other fun stuff. Even designed a small binary protocol to exchange data over BLE
Wouldn't it be easier to just install a bolt lock on your door?
Easier, sure? More fun? Probably not.

It is a workflow graph automation site (drag and drop and connect nodes), but is a toy and only allows a local user and local models (both transformers.js and tensor-flow mediapipe), so costs me nothing. Mostly text stuff at the moment, but working on a slate of image stuff this week, may get to audio and video as well, we shall see.
Fascinating. That UI looks like Vercel. What node/graph library are you using? It looks like it would be really useful for some projects I'm working on.
I am using ReactFlow, which has been really nice.
I'm building an app that takes a screenshot every hour from some news websites. It's is a small python script running on my raspberry pi 5 and for now I'm saving the images there.

Basically personalized meal planning and grocery integration. Since the Show HN I posted a couple months back I've been incorporating user feedback to add things like meal prepping, better ingredient reuse across meals, and cooking style preferences.
One of the biggest points of feedback has been adding more grocery stores but I'm really limited by who has APIs to actually integrate with, which is basically just Kroger and Instacart. Walmart has an API but ignored my API access request. Would love to hear if anyone has ideas on how to approach this.

We want to speed up adoption of custom AI, but most people suck at building it (no expertise, money, time, etc.).
We thought, what if you could "Vibe ML" your way to it? Allow any AI engineer or PM to build custom AI directly from their current implementation.
So we built these agents that orchestrate the entire life-cycle of custom AI. We start by hooking into how you use AI, prepare/label your data, detect the best recipes for your task, fine-tune, and deploy it for you. Really tried to simplify the entire process.
We aren't entirely sure about the UX/UI patterns. We aren't going chat first because if most people don't know where to start with ML, how in the world are they going to prompt it!?! Instead, we auto detect the AI tasks you've built and go from there.

It has an ingestion layer where we break apart a project, it's deck and it's slides into relationships like frameworks/visual archetypes, and then save that in a graph database plus a vector database. The user can then query "find me work we've done on geology research that might be relevant to industrial mining"
I've decided to take a break from working on Pirsch Analytics (pirsch.io) until next year and focus on some side projects instead:
1. Shifu (https://github.com/emvi/shifu) - a code-based CMS with admin UI. It's really easy to set up, written in Go, free and open-source, and I already sold a few websites using it. It can be used as kind of a framework to build more specialized features into a website and takes away the maintenance hell from managing a WordPress installation or a similiar CMS with tons of plugins that break with every update.
2. Zenko (working title, repo is private for now) - a very simple and no-bullshit project management software. It will be free and open-source, but I might offer a hosted option for a few bucks (like $20/year for all users of a team). I mainly build this for ourself to replace Linear, because we don't really make use of it. Don't get me wrong, Linear is awesome, but we basically only need an advanced Todo list. Main goals:
* Pull updates on the dashboard by yourself, instead of receiving notifications all the time via email
* Keep it simple stupid - no unnecessary features, no AI, just the bare minimum
* Cheap (for the hosted version, free if self-hosted) and easy to host (again written in Go)
* No feature-creep
3. Last but not least, I'm working on a "game engine" written in Go and SDL2. I do this for fun, but it is coming along nicely and teached me a few new concepts already (like ECS in Go).
I'm building a utility to help DJs find "play-out" versions of tracks they already like[1]. You can play with it here[2]. Streaming services are optimized for Radio Edits. But to actually mix a track, I usually need the Extended Mix, Club Edit, or a specific Remix. Manually searching for the "DJ version" of every single track in a 50-song playlist is tedious administrative work that kills the joy of digging.
Remixify automates the search while leaving the selection to you. You paste a Spotify playlist URL, and it helps you or provides you a good starting point for digging. It groups the results by the original track so you can quickly preview and save the versions you want to a new playlist.
We don't try to recommend new music or use AI to guess your taste. It just finds the usable versions of the music you already selected.

This is cool, I really like a lot of tunes and try to mix them in only to find it hard and just hack to whack it in. I'll give this a go!
Glad it fits a case you have! Always open to feedback too!

Reading practice and assessments for k-12 students, with reporting and tracking for parents, tutors, and teachers. It uses speech to text and quizzes to assess the students reading ability. It picks up skipped words, substituted words, along with metrics on speed and pauses.
I have been testing it with my 2 daughters and its finally at a spot where I don't have to drag them to test it against their will and they are showing improvement. I am working on the marketing now. I have gotten some interest from private tutors but I have a feeling it will be great for the homeschooling community.
Thanks for any feedback! Please leave first reactions as the marketing page is what I am iterating on right now. Don't hold back!
Working on a low cost email service. Ditched Gmail for my custom domains to avoid lock-in risks, and I believe devs really need stupid-cheap ($10/yr 5GB, unlimited mailboxes/domains/aliases/SMTP/IMAP/webmail) high-quality hosting that nails deliverability with zero spam tolerance. Bootstrapped this instead of pricier options like FastMail. Thoughts?

Interesting!
Just curious, if this is a completely greenfield project, why IMAP instead of JMAP?
This is coming from someone who works with IMAP on a daily basis and has rightfully grown a disdain for it.
I have thought about something like this, but what is the plan when law enforcement comes knocking and
- asks you to hand over all information about certain customers.
- accuses you of aiding the illegal activities happening through your service (copyright violations, CP, etc).
Handle it like any other email service does?
I love the bare-bones landing page, many products have landed me as a customer due to that.
Do you have IMAP import? And CardDAV/CalDAV? Edit: also wildcards?
Thanks for your interest. IMAPsync migrations are supported. No CardDAV/CalDAV. For wildcards, do you mean catch all? If so, that is supported as well.

An AI coding tool desktop application written in Rust and Javascript. Cursor, Windsurf and etc uses too much memory on my machine. As an engineer it is important that the tools I use daily are performant and fast and I could use while watching a youtube video or browse hackernews.
While working on the tool I am building some boilerplates to start from, starting with mobile games targeting arcade games like Flappy Bird.
I'm trying to build a native postman alternative using Rust + Iced. I want it to use .http files as its collections and .env files as its environments. So that data is stored in plain text and easily editable by AI and usable by other apps like VSCode rest client.
https://github.com/sharno/zagel
I was hoping it’d be cli focused (didn’t know what iced is) but I’m now glad to see the elm architecture influencing more gui libraries.
I've been working (very slowly) on a cross-platform UI library written in C. It uses as much as it can from the OS without outright using the native widgets for everything. Rather the focus is on letting the user of the library customize the look of the controls as they see fit.
It's unfortunate but native UI (as in, using the native controls with their native look) has mostly died off in my opinion, at least for complex cross-platform applications.
You can try to do it in a cross-platform manner but it never works well. Want to implement a tab bar like VSCode's? Win32 tab bars do not support close buttons (need to be custom rendered) and Cocoa tabs it doesn't even make sense for them to have a close button. In Cocoa you're supposed to use either the windowing system to do tabs (similar to Safari tabs) or custom render everything (like iWork).
So I say screw it, make it look as you wish.
The design of the API is somewhat DOM inspired (everything is built up of divs that can be styled). It's pure retained mode for now, I still need to think how I'll make reactivity work.
On macOS it uses a custom NSView to implement "divs". Drawing is done with CoreAnimation layers. Text editing is handled by a nested a NSTextView control with a transparent background. Could also host a web view in a similar manner. Context menus are native.
On Windows it uses a custom C++ class that stores Windows.UI.Composition surfaces for drawing (could also use DirectComposition + Direct2D). Text editing is handled by a windowless RichEdit control (ITextHost/ITextServices). Context menus are native Win32.
On Linux it uses a custom QWidget with a nested QTextEdit control for text editing. I'm thinking of experimenting with Qt Quick for hardware accelerated rendering like the other two.
I’m finishing up Haskell Brain Teasers (https://pragprog.com/titles/haskellbt/haskell-brain-teasers/)
It’s much shorter than my first book, Effective Haskell, and leans more advanced, especially toward the end. Although the format is puzzle focused I’m trying to avoid simple gotcha questions and instead use each puzzle as a launchpad for discussing how to reason about programs, design tradeoffs, and nuances around maintainability.
working on bringing some basic, banal bits of infrastructure management to real-world traffic issues.
I'm literally trying to fix broken junctions around me.
It's at the same time laughably easy, and wildly complicated.
I'm calling the alternative, correct junction a 'traffic bean':
https://josh.works/traffic-bean
It's relevant to software, sorta. I've got rather a lot of GIS/mobility-related data available here. It's just a rails app that renders a bunch of my strava activity data all at once: https://josh.works/mobility-data
The fixes are entirely accomplishable with nothing more high-tech than traffic cones. They can be upgraded to more permanent and pretty physical objects, but the key bit of the traffic bean finds traffic cones fully sufficient. No half-million USD traffic signals, no red/green/yellow light cycles. continuous flow. safety. peace.
Some stuff that's obvious in some domains, like "at high-throughput times, don't allow key bits of infrastructure be completely unusable".
Bringing this to american municipalities is like trying to speak a language with someone that doesn't speak your language, but demands that you treat them as if they do.
it's been a big, long-running project. Most tradition in the USA is really a fig leaf for supremacy, and people can smell that I'm coming for their supremacy a mile away, and they immediately begin deploying emotional defenses.
Or so it seems.
I've continued to work on an open-source containerized agent framework called Capsule Agents. Lots of progress this month and I have my first one live in my homelab! I'm training for a marathon and its able to send a discord message every morning with the workout on my schedule and the "why" behind it.
Here's the elevator pitch for the framework:
Its built around 3 key ideas I've dealt with inside the agent ecosystem 1. Agents become far more capable when they have access to a CLI and can create or reuse scripts, instead of relying solely on MCP.
2. Multi-agent setups are often overvalued as “expert personas” but they’re incredibly effective for managing context, A2A is the future.
3. Agents are useful for more than just writing code. They should be easy for non-engineers to create and capable of providing value in many domains beyond software development.
If that sounds interesting take a look! https://github.com/brycewcole/capsule-agents

I doubt it'll be of interest to folks here - but my Family recently (in the last couple of years) started to breed ragdoll cats in the U.K.
This has been my personal project to understand where I personally find LLMs useful as coding assistants, and where I don't. One easy to spot example is, front-end + copy. Another area I've enjoyed it is talking through how I'd design and build functionality and features ahead of time.
It's been very interesting, and is helpful to folks I care about, even if no-one else ends up using it!
I’m working on DeepCost.ai, an AI-driven cloud cost optimization tool for AWS, GCP, and Azure.
The goal is to help small teams and fast-growing startups understand where cloud spend is leaking and automatically reduce waste (idle resources, over-provisioned workloads, inefficient Kubernetes setups, and AI API usage). Setup is lightweight, and we focus on actionable recommendations rather than massive dashboards.
We’re still early and testing with a few teams who want better cost visibility without running a full FinOps practice.

A Python ORM, inspired by Drizzle and the like. Whenever I come to Python I'm frustrated by the ORM options. They generally lack type-safety on inputs and outputs, or useful type hints.
SQLAlchemy is an institution but I think it's hard to use if it's not your full-time job. I check the docs for every query. I want something simple for the 80-99% of cases, that lets you drop easily into raw SQL for the remaining %.
I'm going to keep hacking at it, would love to from anyone who thinks this is worthwhile (or not). Also: - The interface for update queries is clunky. Should I add codegen? - Should I try to implement a SQL diffing engine (for migrations). Or just vendor sqldef/similar...?
You have my vote! Go for it! After I left ruby on rails, I always felt like that python ( orm) could be better
Analyzing frontier LLM performance on my favorite daily puzzle game (https://www.nicksypteras.com/blog/cbs-benchmark.html) Next step is to assess how well the LLMs can create their own new, logically satisfiable puzzles in the same style. Then I'll have them battle it out, with one model creating a puzzle and the other attempting to solve it!
Thanks for sharing! I want to have some sort of agentic "helper" to my new puzzles website [1], and I've learned some tips from your post/code, thank you!
Have you given any thought about how to create the puzzles? Do you think it'd possible to create them using LLMs?

I was thinking about what to get my long-distance girlfriend for her birthday which coincidentally was also the anniversary of our first date. So I thought of building her a personal website, installable via tauri so she can view it offline whenever she wants, that has a timeline of all the things we went through: first date, events, trips, moves etc.
Now I want to polish this, make it customizable, add more features like a "Reasons I love you" jar which gives you random notes your partner wrote, and offer it to others as well.
Another thing, it should be a digital living collection of memories and notes for each other and should evolve with the relationship.
Just started with this and building with Elixir and Phoenix.
PS: I realize I might need to update the website. First I wanted it to be more generic and for multiple occasions like anniversaries, birthdays etc but slimming the target down to couples for now to not overwhelm myself. It's the first ever service I'm building.
looks cool! best of luck
https://provenancevault.com/
I started this over the summer when I was moving to a new house and wanted to document the family history behind some thing I own. It's turned out to be more useful than I thought and I've expanded the features as friends found it useful. A developer friend, who I used to work with, joined me and we're both working on it now. It does have a little revenue now but we are far from quitting our day jobs.
I'd really like any feedback from the HN community!
Working on a lightweight gtk3 AI byok client application for linux.
https://github.com/rabfulton/ChatGTK
I am working on a text-editor that allows you to discuss specified file folders with AI agents for knowledge work. It is similar to vs code with chat but for non-technical users and not for code.
I feel like I am constantly fighting LLM interfaces to make available and organized the context needed for discussion. There just seems to be way to much copy pasta into and out of the infinite scroll interface. I also find the output tough to quickly edit and discuss with the chatbot.
It is simple enough but I couldn't find anything like it and it has quickly become one of my favorite tools. I am build over buy to a a fault, so if there is something out there like this already I would not be surprised.

Petra (Obsidian CLI) and Petra-Bridge (Obsidian API for the CLI tool integration). https://github.com/H4ZM47/petra-obsidian-cli ; https://github.com/H4ZM47/petra-bridge
This was a "scratching my own itch" project that I cooked up because I was tired of Claude et al cluttering up all of my stuff with random markdown files. Just a simple Obsidian plugin to serve an API that the CLI tool can use to interact with the Obsidian vault. I use a Claude Skill to get the model to create all of those random markdown files in my Obsidian vault, and read from them when it needs context for something. It's working really well for me so far!
I've spent the last week starting to hand port SeL4 to rust. Mostly because I want to learn how kernels & capabilities work. This seems like a fun way to get my hands dirty with operating systems without needing to invent everything from scratch.
To be clear, there's no benefit to using rust over C for SeL4. SeL4 is formally verified - which provides a level of assurance far beyond what the rust compiler can check at compile time. I'm really just doing it for fun and learning. I've been wanting to really understand sel4 for awhile, and there's something wonderful about learning it from the ground level.
So far, I've got a stub booting. The CPU successfully boots into 64 bit mode and starts running my rust code. I'm starting with x86_64 because thats whats on my desk. At the moment I'm porting the code which locates the root process via multiboot, so I can set everything up in memory correctly.
If anyone is curious, here's the repo: https://github.com/josephg/sel4-rs
Its pretty bare bones for now, but everything starts simple!

What is your innovation over https://tiddlywiki.com/
Working on https://usedigest.com — a personalized daily digest.
It aggregates data from across the web into a single feed, pulling in news, weather, newsletters, social posts, Reddit, YouTube, and more.
I also finally launched my first iOS app that goes a step further. During onboarding, you set your preferences once. From there, AI automatically prepares your daily digest for you. Each morning, you get a notification when it’s ready, with everything relevant for the day ahead: meetings, weather, health data, commute insights, and the news you actually care about.
How it differs from mailbrew?
I believe it was sold off and is no longer maintained -- their changelog shows no updates since 2023. We constantly update the platform, and have more sources available plus a mobile app.
A security-focused "check engine light" for your shell prompt: https://github.com/erichs/dashlights
There's a gap in most security tooling: it's not IN the terminal with you. It doesn't have enough context: your environment, your repo state, your current directory, etc. to catch the small hygiene mistakes that accumulate over the many tiny decisions you make every day to ship code and learn new tools. Those "cut corners" add up, and can lead to costly blunders.
Dashlights attempts to bring awareness and visibility to your immediate shell context.

I just released the first alpha version of my RISC-V hobby kernel, written in Ada: https://github.com/ajxs/straylight
My next step is documenting how all of the subsystems work (such as virtual memory, allocators, drivers, etc.), then lay the project to rest. I don't have any grand ambitions for the kernel. The project was just a labor of love, and a way to learn some interesting things! Hopefully some of the documentation can serve as learning material for other people interested in osdev.
Making a realism game mod to Battlefield 6, which recently came out.
If you have played military sim (Milsim) games like Project Reality, Squad or Arma you might appreciate it.
Its quite cool how the game devs have made a lot of tooling to use; they use Typescript to hook into in-game events and functions.
There is a whole community making lots of content too:- https://bfportal.gg/
Currently I am working on an insurgency game mode; where one team has to defend some caches and use guerilla tactics, whilst the other team has a smaller size but the advantage of firepower and vehicles.
Hopefully have it released by Christmas time.
I was into playing the mods for the original and played some of 2142 on PC.
Has the official multiplayer gameplay held up? I did try a release around the time of RDR2 on Xbox and it had seemed like pay to play may have messed with it at some point.
Curious if the mod support seems like a jailbreak from the official multiplayer.

I'm working on building out a microservice ecosystem on OCI. I'm not formally educated so I just sort of stack things up and tear them down. I hardened my server and I am running dockerized services. I'm also running a web server that hosts the very start of my long-term personal site. It's been pretty challenging, illuminating, and down right fun. I've been putting down the controller for a terminal!
Seriously, I'm very proud of myself for the little I've accomplished so far. I don't have friends in tech so I don't get to talk about it or bounce ideas off people.
Thanks for letting me get that out!
Sounds cool, I tried kubernetes out on a few rpi4 devices as a small build farm, but that didn't quite work out, too resource hungry for the small PIs. Getting sth like that going with less RAM, infrastructure would be cool!

Awesome! Good articles. I wonder why you didn't use first a more traditional decompiler such as Ghidra or HexRays to generate "almost-C" and then use Agents to give them meaningful name and semantics?
https://finbodhi.com — It helps you track, understand, and plan your personal finances — with a double-entry accounting. You own your financial data. It’s local-first, syncs across devices, and everything’s encrypted in transit. Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more.
Soon, we will have benchmarking capability. You would be able to compare your networth growth with inflation, compare your investment returns with benchmark etc. We would support both nav and value based benchmark. The topic is interesting in itself, and somehow, not emphasized/available in most tools.
Asset price fetching and benchmarking works best for Indian markets. We would like to build better support for international assets and benchmarks, but haven't figured how to get the data.
NOTE: you can try demo without signup, but it doesn't work in Firefox Incognito mode.

Super silly question maybe but what is the benefit of just using something along the lines of a word document?
Probably just a matter of preference imo =)
I was using another paid tool my accountant suggested. Then I decided to build my own tool, but free and open-source. It gets the job done at least for me plus I have some ideas how can I improve it further. For example I built a simple automation where an invoice is generated every month, emailed to me for review, and then I forward it to the client.

I'm working on Tech Talks Weekly which is a free weekly email with all the recently published Software Engineering podcasts and conference talks in the past 7 days.
Every week I pull all the new talk recordings from hundreds of conferences (Devoxx, KubeCon, PyCon, QCon, LeadDev, JSNation, and many more) and even more podcasts podcasts. I feature the ones I think are must-watch with short summaries written by me, then include a list of everything else uploaded that week.
It started as a personal project to fix my own messy YT subscriptions and RSS feeds and now 7,500+ people read it.
I also publish extra editions from time to time like “The Most Watched Talks of 2024” which made it to the HN front page.
If you watch software engineering conference talks or listen to podcasts, you might find it useful.
I’d love to know what you think!
I've built this website helper to browse these "What are you working on" comments: http://waywo.eamag.me/
Updated manually so expect some delay :)
Cool. What do you mean by 'manually' and 'some' delay?
If you have a list of posts you pull data from, it would be nice to have a simple clickable list of them all on a separate page. Also, (month year) could go next to neat 'View on HN' on each item.
Do you parse all 'What Are You Working On?' posts (see https://news.ycombinator.com/item?id=46266893)?
Have to run a script and hitting free tier limits. I'm searching posts via algolia and then fetching them via firebase api
So, not bad in terms of 'manual' update, but still needs some of your time, right? Anyway, interesting to be able to see these posts in this way. Nice work with tagging - will check/explore how these work.
I’m still working on MLSync.io, an ETL platform designed to remove the technical friction of synchronizing MLS data using RESO protocol and provide simple access to the MLS data via SQL and REST API.
And as everyone now, I'm experimenting with LLMs to bring some new AI-related features to the service.
On another project, we've now beta testing (in ordination) Asus GX10 processing power running on-device LLMs for _local_ processing of patient medical data for 'differential diagnoses, implant plans and risk profiles in real time while the patient is in still in the chair'.

Working on Bold (https://boldvideo.com)
Video intelligence platform for coaching programs and training companies. The problem: these businesses sit on 200-500+ hours of video content that becomes a "content graveyard" - students can't find what they need, coaches burn out answering the same questions, churn stays high.
We do deep transcript + metadata extraction, then layer RAG search and an AI assistant that can answer questions with timestamped citations back to the exact video moment. Think "ChatGPT for your video library" but with accurate sources instead of hallucinations. Tech: Phoenix/Elixir backend, Next.js portals, two-tier RAG architecture.
Currently serving a few coaching programs in high-touch sales mode. Would love feedback from anyone who's built RAG systems over media content - curious how others handle the signal extraction problem (transcripts are noisy, you need to identify what's actually being taught vs filler).

Wanted to save up a few tokens when passing data to LLMs and did not like anything on the market, so I made minemizer.
Minemizer is a data formatter that produces csv-like output, but supports nested and sparse data, is human readable and super simple.
It produces even less tokens than csv for flat data, due to most tokenizers better tokenizing full words that contain a space before the word, and leads to less fragmentation.
There are many cool things I discovered while running tons of testing and benchmarking, but it's getting late here.
Code, benchmarks, tokenization examples and everything else can be found in the repo, but it is still very WIP: https://github.com/ashirviskas/minemizer
Or here: https://ashirviskas.github.io
EDIT: Ignore latency timings and token counts in "LLM Accuracy Summary" in benchmarks as different size datasets were used to generate accuacy numbers while I was running tons of experiments. For accurate compression numbers see compression benchmarks results. Or each benchmark one by one.
I will eventually fix all the benchmark numbers to be representative.
Why the name Minemizer instead of something like Minimizer?
Back in 2019 I created a Google Spreadsheet titled "family debts" that allows my family (4 siblings and my parents) to record when we owe each other money, and periodically settle up. I later learned that I recreated Splitwise, but having something like this with trusted folks has been hugely useful. We have over thousand entries, and use it constantly for splitting gifts, buying something at the store for someone, etc.
Om Friday after Thanksgiving I spent half a day building a telegram bot that accepts an address and a list of Amazon links, and in turn orders the item (at a discount since it uses my Amazon credit card), and adds it to the above "family debts" spreadsheet.
I really like the idea of programmable, trusted lending like this, and feel like it could be extended to other groups that you implicitly trust.
Writing articles about how to test frontend apps (mostly react based apps) at https://howtotestfrontend.com/ Adding some final bits to some new vitest browser mode content this week hopefully.
I've spent a considerable amount of my free time over the last few years working on an open-source game engine for making Zelda-like games (link in profile). It's been around for a few decades, and I played it when I was a kid - and now I'm contributing heavily to it. To give a since of scale, there's ~1000 custom fangames made in this: so pretty niche, but if your thing is Zelda it's got some real gems.
Most of my time has been spent practically rewriting the engine from just single-screen play areas (like Zelda 1) to be free-scrolling (like Zelda 3). I've also put lots of work into supporting all platforms (was just Windows; now it's also Mac/Linux/Web). And I've delved into tons of interesting programming projects while working on this: a deterministic record + replay testing system; a garbage collector for our custom scripting language; JIT compilers for x64 + WASM; a VS Code language server; the list goes on...
Anyhow, this month I'm trying to polish it up as much as I can so we can officially release the next major version.
I just built myself a DYI TRMNL (https://taoofmac.com/space/reviews/2025/12/13/2200), decided to hack together my own server for it, and (serendipitously) got asked if it could be an official contribution: https://github.com/usetrmnl/byos_fastapi
Then I decided to hack my own ZigBee power meter (to keep track of my meter’s LED pulses) and fought with CMake for eight hours straight, because embedded.
It was a nice weekend.
A typed execution graph for Go. You write functions with typed inputs and outputs—Docket infers the dependency graph, runs independent steps in parallel, and caches what you tell it to. It integrates with River and a number of data stores.
I spent a year attempting to adopt Temporal at scale, and 6 months trying to wrangle some multistep data enrichment and ML pipelines. This is what I wish I'd had with what I learned

I am working on the android version of this app. It is a tiny tool for options trader to see all the premium on one screen. Here is the reddit thread where I initially launched it: https://www.reddit.com/r/Optionswheel/comments/1nlelbp/i_mad...
If you trade stock or options, would love to get your feedback! Thank you.
I am working on two things.
The first is a customizable digital math workbook. Currently the demo covers fourth grade math. There is a practice mode where you can select the skills you to want practice. There is also a customizable dashboard where you can setup your own widgets to practice math skills in different ways. I am working on some pre-made dashboards to help users get started. The next plan is to cover fifth grade math skills. My plan is to cover first grade math up to Calculus and High School Physics. I envision it as a companion tool for Khan Academy/Math Class/Math Books. Check out the demo. No signup required. Progress is only stored locally.
https://demo.numerikos.com/
The second thing I am working on is an application to practice Cangjie. It's a Chinese input method that has been around for a long time. It is based on a visual decomposition of characters. Each character is represented by one to five codes and the majority are unique. My application teaches Cangjie like keyboarding (QWERTY) is taught to young students. You learn the location of the keys, then some basic words, then start typing sentences. I also have a free demo for it as well.

Glad to see you're doing this! I was wondering if the currency button could be changed. Defaulting to Euro is fine, but being able to switch that shortcut would be handy.
I still need to update the UI to reflect the changes of the locale and language, but that should be the easy part.

We’re working on an AI-first interview platform for developers: Valuate.dev The usual approach to coding tasks doesn’t work anymore - companies are looking for AI engineers, yet it’s still unclear how to assess AI proficiency.
Our goal is to design challenges that combine prompting + coding, allowing us to score both how well a candidate prompts and how good the resulting code is. The aim is to bring measurement to AI prompting skills - how well-aligned prompts are and how candidates handle LLM-generated code.
At the same time, we want to keep a strong human balance in the process: hiring is a two-way street, and screening shouldn’t be fully offloaded to AI. We’re human-first.
Several tasks are already live - you can try them here: https://valuate.dev

I'm making a cat themed puzzle game for my wife using NiceGUI, MindAR and some cat shaped sticky notes. Each note has a name and a secret code. I've hidden 20 of these around the house. I set up a single page app in NiceGUI to display a grid of the lost cats. When you click one it'll display their name, a clue to its hiding spot and an optional hint. 5 of the puzzles use MindAR that will display AR image cards over different art pieces and book covers in our house. I have the NiceGUI page and MindAR set up on one of my Proxmox LXCs that I use for various Flask servers.
Taking a break from software to remodel a house by myself. The plan was just to redo the kitchen and a bathroom and be done by August, so naturally it's now December here in Minnesota and the house is missing most of its wiring, pipes, insulation, and walls. :) I'm having a great time though and just started producing videos about it: https://youtube.com/shorts/6QDOXxh99PY?si=NOjvNVEVHwQt180A
LLMatcher - blind testing arena to find which AI model actually works best for you.
You enter prompts, compare two anonymous responses, pick the better one. After voting, it reveals which models you preferred. Built it because model benchmarks don't match real-world preference, and blind pairwise comparison cuts through the hype.

Currently working on Skyscraper, which is an iOS native Bluesky client: https://testflight.apple.com/join/RRvk14ks
Primary goal with the project was to create a Bluesky client that I wanted to to use. While the standard Bluesky app is fine, I wanted something more reminiscent of Tweetie, Tweetbot, Twitteriffic, etc. Something that feels at home on the iPhone. With the transition to Liquid Glass, felt like a good time to practice and get to experience the new UI with a new project.
Still in what I call "alpha", but pretty feature rich. Support push notifications, lots of discovery/feed following features, search tools, moderation setting management, post translation, and much more.
If you use Bluesky and are an iOS user, there's still space on my TestFlight and would appreciate any feedback or comments!
I have been working on a customizable AI voice dictation tool using Pipecat's framework to swap between many providers and models, including cloud or local.
Started off as an open source alternative to Wispr Flow for myself as I wanted to have more control over the formatting rules as well as model choice but after sharing with friends and presenting it at my local Claude Code meetup, I was encouraged to share it more widely.
The desktop app uses tauri so it is cross-platform compatible and I have tested it working on macOS and windows.

An AI assistant plugin for Logseq. https://github.com/shovon/logseq-ai
It allows users to "chat" with their Logseq graph. Think of it like a "Cursor for Logseq". I hope people find it useful. I have on numerous occasion wished that I could have easily asked about a specific block on my graph, and would provide an intelligent response, also somewhat influenced by the contents of the entire graph. It's still a work in progress.
It's fully open source.
*Supex* - Agentic coding for SketchUp.
Working on a house renovation project in SketchUp, I wanted the same workflow I use with Claude Code: describe what I need in natural language, let AI write and execute the code, iterate quickly.
So I built a bridge. Python MCP driver talks to a Ruby extension inside SketchUp via JSON-RPC. Claude Code can now write Ruby scripts, execute them directly in SketchUp, take screenshots to verify results, and introspect the model - all without leaving the conversation.
Still very early (macOS only, requires SketchUp 2026), but it's already useful for repetitive tasks and parametric designs. "Create a spiral staircase with 15 steps at 18cm rise" is more fun than drawing it manually.

I'm working on ffl (https://github.com/nuwainfo/ffl), an Actually Portable Executable (APE) that turns any file or folder into a secure P2P HTTPS link via WebRTC.
Like llamafile, it's built on Cosmopolitan Libc. Getting the full Python stack + WebRTC to run as a single APE binary was incredibly tricky to pull off, but the result is super convenient. I mainly built it to solve the pain of moving large files (logs, DB dumps) in and out of containers—now it's just one command.
The repo has a demo showing a round-trip transfer between Windows (x64) and Android (arm64) using the same binary. I hope you give it a try!

I am build a toolkit for it too:

Or https://github.com/blmayer/bgtk
I think it is nice that we can just write to a buffer and it appears on the screen. Very little abstraction is needed. Hope you like it.
I also made some progress on my hardware projects, but I'll keep a low profile for now.
This holiday, I built a cool Christmas project. It's a real-time experiment.

I'm working on a hardware/software utility to play Switch/Switch 2 games remotely with my brothers. I found a way to emulate a Switch Pro Controller using a Raspberry Pi Pico based on several different sources (look in the README for more info). I used that to write a firmware for the Pico (with the help of GPT Codex 5.1).
Then I wrote a Python program that connects whatever controller my brothers want to use (as long as it's supported by SDL2.0) and forwards that data from their computer, through Parsec, through a USB-UART adapter, to the Pico, then to the Switch. I then have a low latency capture card (Magewell Pro Dual HDMI I got off of ebay for $100) forwarding the video and audio from the Switch to my PC which I share to my brothers via Parsec. The audio was a bit tricky to get right, and ended up having to use a Virtual audio cable and Voicemeeter potato (a software audio mixer) so that both myself and my brothers could hear the audio.
It works surprisingly well and the latency is pretty low. I even got rumble working! (but not motion controls. If anyone wants to attempt it, I will accept PRs). I haven't done any formal benchmarking for performance, but my brothers and I were able to play Smash Ultimate without too much bother about latency.
You could also use the accessory Python library I made to automate switch controller presses (look in the examples directory). Might be useful for TAS speedruns?
The project is here for anyone interested. It's a bit rough and needs some cleanup and maybe a video tutorial on remote setup. But here is the WIP:
https://github.com/jyapayne/switch-pico
I’ve been working on a TLS proxy/TLS terminator that can handle 3000 TLS handshakes per second (basically an stunnel replacement, but stunnel crashes at under 100 handshakes per second) as a pet project, but I’ve realized that with some polishing this can be really useful.
https://github.com/novotimo/tlsproxy
This is still in development (todo are privilege dropping, in place config reloads, log burst suppression, multiple listen sockets (which paired with the Linux kernel gives free load balancing capabilities), and detailed TLS configurability), but it already matches both nginx and HAProxy’s speed (entirely bottlenecked by OpenSSL crypto by this point) at a tiny fraction of the attack surface and memory footprint (10-15kb per worker process last time I checked).
If anyone wants to take a look, please roast my code :)

It's essentially a book progress tracker. There are many apps that allow you to add the books which you are reading currently, but not at what pace. It's simple, no complicated stuff, no AI shenanigans.
Created as I was overwhelmed by the number of books I want to read and thought it would be helpful to plan ahead.
You add a book name, number of pages and how many pages you want to read in a day. It calculates and gives you the number of days and on which date you will finish. It's also flexible to increase the number of pages so that it can recalculate.
It's a PWA for now. Still working on notifications and stuff.

neat idea!
Most recently (yesterday), vibe coding a better interface for Roblox screen time: https://github.com/astrostl/blockblox .

Building Contextify - a MacOS application that consumes Claude Code and Codex transcripts, stores them in a local sql db.
The main window uses Apple’s local LLM to summarize your conversation in realtime, with some swoopty UI like QUEUED state on Claude Code.
I’ve just added macOS Sequoia support and a really cool CLI with Claude Code skill allowing seamless integration of information from your conversational history into aI’s responses to questions about your development history.
The CLI interface contract was designed to mutual agreement between Claude code and codex with the goal of satisfying their preferences for RAG.
This new query feature and pre-Tahoe support should be out this week, but you can download the app now on the App Store or as a DMG.

Looks awesome for solo / indie devs.
For my small software shop I'd like a team version of this:
- collect all prompts/chats from all devs for our repos - store them somewhere in the cloud - summarize them into a feed / digest
That’s an interesting direction. I haven’t thought of this in multiplayer sense.
Would you see this as something that is sort of turn-key, where a central database is hosted and secured to your group?
Or would you require something more DIY like a local network storage device?
And similarly would you be open to having the summaries generated by a frontier model? Or would you again need it to be something that you hosted locally?
Thank you for the feedback and interest.
A central service. Hosted, secure, frontier model is fine. I’m thinking this through it’s probably something GitHub or an addon should provide.
But maybe it starts local with an app like yours anyway. I do a lot of solo hacking I don’t want to share with the team too. Then there is some sort of way to push up subsets of data.
I can see github providing this, but it would still be at the git-operation level.
What I've found using this contextify-query cli in talking to my project(s) CLI AI history is substantial detail and context that represents the journey of a feature (or lack thereof).
In high velocity agentic coding, git practices seem to almost be cast aside by many. The reason I say that is Claude Code's esc-esc has a file reversion behavior that doesn't presume "responsible" use of git at all!
What I find interesting is that neither Anthropic nor OpenAI have seized on this, it is somewhat meta to the mainline interpreting requests correctly. That said, insights into what you've done and why can save a ton of unnecessary implementation cycles (and wasted tokens ta-boot).
Any thoughts on the above?
If you're open to giving the app a try, and enable updates on the DMG, the query service + CC skill should drop here in a few days. It's pretty dope.
Another alternative for update notifications is to watch the public repo where I'm publishing DMG releases: https://github.com/PeterPym/contextify/releases
Anyhow, this is really cool feedback and I appreciate the exchange you provided here. Thank you. If you have any further thoughts you want to share I'll keep an eye on this thread or can be reached at rob@contextify.sh
I got a couple new toys for birthday/xmas: the GPD MicroPC 2 UMPC and the M5Stack Cardputer.
The MicroPC is great because it makes it super easy to code and hack on something in places where it would be too awkward or annoying to whip out my laptop, and the Cardputer is just a fun little toy because it's so open ended and hackable. I've been writing an app for Cardputer to control my thermostat remotely, and I've had a lot of fun grossly overengineering the needless amount of concurrency I have added through FreeRTOS.
Something oddly satisfying about using a micro PC to program an "even more micro" PC. What a cool time to be alive; I would have killed for this kind of stuff as a teenager!
Stuff like the MicroPC excites me. Even though, logically, you hardly need need a micro pc but the hacky excitement of using it is worth it. I have also been looking at purchasing the MNT research pocket laptop.
On Thursday I learned about ulid[0] which I think really neatly solves the problem of text representation for UUID v7. However, I also like the idea of prefixed ids, although I haven't used them in anger.
Yesterday I built most of a Postgres extension, using the excellent pgrx[1] project, that build on ulid to add prefixes. With it you get something like this
The aim is for it to be the same size as a UUID in storage, but I haven't quite gotten there yet.I haven't pushed it to GitHub yet, but it's fairly done at this point.

I'm working on finishing my JS KV compatibility library polystore [0], the goal is to make a widely compatible library to connect to many stores so that you can have a wide range of stores easily accesible.
For example, you make an API client library, now you can add polystore and accept multiple cache stores without writing all the compat layer yourself. This is a problem I've had multiple times in the past.
Or you make a project with cache, having it in files for local dev (highly debuggable) and then with Redis in prod is a simple ENV var change:
I've made many other libraries and projects during the years and having a single library handle all of this would be great.[0] https://polystore.dev/
I'm working on a no-code admin dashboard.
A small startup generally needs to explore and edit the production data. They would either build an admin dashboard, which is expensive, or use a database tool, which is bad for security. Not to mention a tool like pgadmin and dbeaver is clunky because they focus on database administration.
Backdoor is a self-hostable database querying and editing tool for teams. It reduces the need of an expensive admin dashboard. You can configure access control and validation policy for each user. The activities are tracked. It saves money and time, and it's more secure.
You can have your non-technical CEO, customer support, and sales to edit the production data in a safe and secure manner.
It currently supports Postgres and ClickHouse.
I'm looking for early users to iterate with. If this resonates with you, please reach out to me through the github repo: https://github.com/tanin47/backdoor
I'm building a temperature controlled dough proofing enclosure based on ESP32, an IKEA Samla storage box and an inexpensive silicone rubber heater. It's delightfully impractical-- purely a first hardware/MCU learning project and a holiday gift for a relative who I think will appreciate it.
I'm impressed by how far I can get "vibe making". Most of my professional experience is in high-level software, but AI gets me unstuck quickly when I don't know something specific to ESP-IDF or the hardware. As of today I've got a circuit tested, firmware nearly complete, and a custom PCB en route from JLCPCB.
One limitation I’ve noticed: ChatGPT struggles with the details of part selection (e.g. choosing specific temp/humidity sensors or connectors). Adding datasheets to the context helps a lot, which makes me wonder why this isn’t something the model can do or at least ask for.
Seems like a fine tuning opportunity

Honestly, building a desktop app is so refreshing after spending a decade or so building web apps.
Published my first AUR package this week. It's called bleep, a simple interval timer that beeps.
The idea came from cooking bolognese. I needed something to remind me when to stir. So I wrote a small Go tool that just beeps at whatever interval(s) you set.
Then I kept adding stuff. Verbose mode with a live countdown, pause/resume with signals, and a JSON output mode that works with Waybar. That last one is actually my favorite part. I get a little timer in my status bar that changes color when it's counting, paused, or beeping. Click to pause. Works great for pomodoro or just keeping track of things while working.
I switched from Mac to Arch and wanted to try the whole AUR thing. Used GoReleaser to automate the build and publish. Took some fiddling but it works now.

We've been building https://nimstrata.com/ for almost three years now, we put Google's Vertex AI product discovery algorithms on Shopify and Salesforce ecommerce storefronts.
At a high level, Google does not have a product culture, so there is a lot of white space for companies like ours to make adopting Google Cloud APIs much easier for less technical users.
It's also wild how much Agentic AI is creeping into all of our conversations - this space is constantly evolving as we're building.
Plug-That-In [https://plugthat.in] (Mac App; Paid)
An annoying little laptop charging reminder utility that does the job.
---
There are times when I'm deeply immersed in focused work, a meeting, or engaging video content and end up missing the usual low-battery notifications on my MacBook.
When the laptop suddenly shuts down, it's followed by the familiar and frustrating walk to find a charger or power outlet. It can be annoying and occasionally embarrassing, especially when rejoining a session a few minutes later with, "Sorry, my battery died."
Over the past few weekends, I built Plug-That-In, an app that introduces "floating/moving notifications". These alerts follow the cursor, providing a stronger, harder-to-miss nudge regardless of what’s happening on screen.
The app also includes a few critical features:
- Reminder Mode: When the battery reaches critical levels, the app emits a configurable alert similar to a car's seatbelt warning, continuing until the battery is addressed.
- Do Not Disturb Settings: Customize alerts and sounds based on context, such as when system audio is playing, a video is active, or the camera is in use.
It grew out of a personal need, and I'm glad to see it used by over 50 people in the past month.
instant buy. thanks!
EDIT: funnily enough seems like its using a lot of battery?
Glad you found it relevant, and thanks for sharing the feedback.
Not going to deny that it was a bummer to read your second line, lost all the Endorphins earned from reading the first one. Nevertheless, I want to fix this if it's a legit issue.
Do you mind sharing more details on the battery consumption from the app?
I'm using IOKit power source notifications and hearing this feedback for the first time. (personally using this on my work [old M2] and personal [new M4] MacBooks for the last ~2 months).
After reading an article about doing 10,000 pushups in a year (https://wjgilmore.com/articles/10000-pushups), I created "push10k", an iOS app to help me keep track and stay motivated. It's free (no money, no ads) in the iOS app store: https://apps.apple.com/us/app/push10k/id6754811078.
I built https://nofone.io . I ingest health insurance policies and provide insights to insurers on how to improve them and doctors to know what insurers expect to see in documentation and evidence. My hope is to improve the denial situation and standardize medical necessity criteria down the line.
This is awesome, but it makes me sad that it's necessary.
Thank you! Yah it really is sad, I always joke (but really half seriously) that the goal would be to make the platform unnecessary one day.

https://fooqux.com/ - an experimental article aggregator about software development. For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website. The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experimental features like annotations, questions, etc. I hope this service might be useful to others as well.

Building https://localhero.ai, automated on-brand i18n translations that run in your CI pipeline. Right now I'm working on better .po/gettext support, based on feedback from an early customer. With gettext you usually keeps source strings in the actual source code. So I'm building a workflow where non-technical people (PMs, designers) can edit translations in the web UI and then easily generate a PR with both code changes and translation file updates. Trying to make translations work smooth for both automated CI pipelines and PMs/designers who don't live in Git, when translations are checked into the repo. Also going through my network, talking to devs and localization folks to understand what could be improved in their orgs for translations.
Nice! We use an internal workflow with translations by llms at Minut. This looks smoother, esp as everything is driven through the PR. Swapped out lokalize for cost reasons.

At work I'm working on autonomous agents for web application testing, and in my spare time I've been taking some part-time evening courses at the local university for the first time.
Last term I did a course on nuclear weapons and disarmament (and learned to write my first ever academic report!)[0], and this term I'm just about to give a final presentation for an introductory life sciences course (actually just posted a runthrough recording [1]). Next term I'm hoping to get into a course about cosmology!

I am currently on the job hunt and made a job application tracker. It's a CSR React app that uses LiveStore (https://livestore.dev/), a reactive state library built on top of WASM, SQLite, and OPFS. The app enables you to track applications, leave notes and updates, and gain insights into your data, while storing your data completely within the browser.
I’m building an online memorial product in China, currently used via a WeChat mini-app and web pages by local governments and cemeteries for digital remembrance.
I’m now exploring a global version (web + app) for families worldwide — especially those separated by distance.
The current product is in Chinese, but the idea is universal. I’d love feedback, and I’m open to marketing or distribution collaborations.
Product (Chinese): https://www.yunmu13.cn/products/
We’re also considering adding AI capabilities — e.g. AI digital humans, voice cloning, or other respectful AI applications for remembrance in this sensitive domain.
Still working on the Mint programming language (https://mint-lang.com/) with a 1.0 release in January :). I'm happy with the current feature set, so I'm just polishing and optimizing where I can and giving the documentation a throughout look.
What are your thoughts on Marko? https://markojs.com/
IMHO, Marko and Mint target different things. Mint was specifically made to create Single Page Applications, whereas Marko seems like more for general all things web.
I'll try to add Marko to the feature comparison page soon: https://mint-lang.com/feature-matrix
Building https://canonicalschema.com/, I started with a simple CSV viewer because none of the existing online tools supported large files or provided flexible column statistics and filtering to easily understand the data. My plan is to grow it into a full application where users can more easily manipulate and analyze CSV or spreadsheet data.
I recently open-sourced my first ever tool! and I'm super excited about it guys
It's an HTTP request replay and comparison tool in Go. You can replay real traffic, compare multiple environments, detect broken endpoints, generate HTML/JSON reports, and analyze latency
It’s currently at v0.4, so I’d love any feedback, suggestions, or ideas for improvements. (Be gentle, I haven’t used Go professionally, however it’s my main language for personal projects )

Here's the landing page too: https://www.replayer.online/
I have built a AI powered home improvement platform with live consultation with pros.
I am not sure if I will go live with it.
It allows those professionals experts across the USA provide help to Do It yourself consumers for a fee. Consumers can be anywhere.
So I married sort of like Uber (rent skills) + upwork (rent + fees) + FaceTime + e-commerce. realtime audio transcription that identifies parts you need and builds a list for pros and you to review which you then go shop.
: Meet Handy — AI + Live Experts for Every Fix.
: Instant, intelligent home-improvement help — see it, solve it, and shop for it, all in one live session.
Live Video Calls with Pros Instantly connect with verified experts via real-time video. No scheduling hassle — just point your camera and get help.
AI-Powered Visual Assistance HandyLens AI analyzes what the camera sees, highlights problem areas, and guides both consumer and pro with contextual prompts.
Domain Expertise Specialized AI Packs (Plumbing, Electrical, HVAC, Painting, etc.) ensure every session applies the right technical and safety knowledge.
Actionable Fix Path Each call ends with a clear, AI-generated “Fix Report”: what to do, parts needed, and next steps.
Commerce & Trust Built-In Integrates with retailer catalogs for instant part links, and captures verified pro ratings and summaries for quality assurance.
Paid Live Video Sessions (Primary Income) • Pros earn per-minute or per-session fees for live video consultations. • Example: • $3–5 per minute • Typical 10–20 minute call → $30–$80 per session • No travel time, no fuel, no tools, no overhead.
Pros log in when available (between jobs, evenings, weekends). • Ideal for: • Independent contractors • Apprentices with experience but limited licensing • Semi-retired pros • Pros during slow seasons
This unlocks underutilized labor.
⸻
4. Lead Conversion (Optional Upside) • If an issue requires in-person work, pros can: • Convert the session into a local job lead • Or refer the job and earn a referral fee
Cross-platform game framework for/in the Odin programming language. It's also the foundation for my first Steam release. The plan is to get something out on Steam, roll with the punches (bugs,) then open it up for general-use. I say "framework" instead of "engine" because the scope of the project is to make the decisions the beginners get stuck on and free them to make a game. That's a smaller goal than what you see with Unity, Godot and Unreal, but I am already at the point that I'd rather use my thing than Godot.
Publishing everything local councils do in the UK at https://opencouncil.network - trying to help people feel like they know who and what they’re voting for next May.
It’s been incredibly rewarding to see people’s changing opinions of their local government
Super cool! We are doing the same thing in California: https://locunity.com/
I'd love to swap notes - hmu at dev@locunity.com !

It's a travel tool for business travelers that figures out your suggested departure times for your entire itinerary based on predicted traffic patterns. Think Flighty but for all the non-flight parts of your trip.
You first build a travel itinerary with your legs - flights, activities, hotels (and hotel returns) and it tells you things like "leave your hotel at 7:40am" before your 8:30 meeting - in a single itinerary, no need to do the google maps acrobatics for every two items in your itinerary. While it's aimed at frequent business travellers I personally use it for all family leisure travel and daily itineraries around town as well - "do I have time for lunch at home after my son's class or should we bring packed lunch". I built it as during my time working in developer relations I traveled a lot, and always built unnecessary buffers and kept nervously glancing at my watch or phone to see if my planned time to leave still holds.
Tech-wise, currently it's Remix web app with a NodeJS/Fastify backend and Supabase for storage, and relying on google maps for route duration calculations. I want to expand it to native mobile clients in the future as well.
I am using it as playground on product thinking, ruthless prioritisation based on user benefit, figuring out unit pricing and economics, sensible architectural design, and exploring how including AI-enhanced features here and there can help make the product better, not just include them for their own sake.
I've been hard at work building a weightlifting workout tracking & analytics app. Its main selling points are being iOS native, being a one-time purchase, and being completely private (does not depend on a backend, but still saves data to the cloud).
If it sounds interesting, you can sign up for a waitlist here, it even includes some screenshots: https://plates.framer.website/ (excuse the website being on a framer domain, i promise the app is far more professional)

Site where you can read and generate graded Chinese stories, in order to learn Chinese. What's a graded story? It's one written with the vocab of a {X} year old. Words are often repeated, so that you can learn from the left-and-right context. I normally pay for book versions of these, so I thought, why not make one that's online and free?
Super specific use case, only a handful of users(mostly friends with free account). https://apps.apple.com/nl/app/multipark-amsterdam/id67469835...
Use Case: Assumption: You have access to your friends visitor parking login in Amsterdam.
You are going to a restaurant/or visiting a place near their parking zone(geo fenced polygon). You want to pinpoint a point in map and drive to that point. Being 100% sure that you can park at that point. Automatically pick a meter near there spot and park almost instantaneously. Then this app is for you :D
Added a fifth project this month. Most likely very unwise...
1. probe.bike - tell stories with your bike rides. It allows you to aggregate your cycling trip into one datapoint. Will likely break this out to skiing over the break and rebrand slightly. Adding yearly cards as we speak!
2. flopper.io - I'm seeing traffic rise and rise for this and it's been a great way to translate my every-increasing understanding of AI Infrastructure architecture to a new project. It acts as a benchmark website for GPUs and systems (e.g. Nvidia NVL72.
3. llmstxt.studio - still feel like llms.txt as an idea make sense - so hedged that and but let's see. Got my first customer this month. B2B and need more features/marketing.
4. rides.bike - the oldest - a catalogue or well researched cycling destinations and information about destinations. Will be adding more very soon!
I like the bike related projects. Not sure people are willing to pay for a service like probe.bike, but it's certainly a growing market.
Thanks!
It's difficult. It takes time away from my evenings and weekends at the moment and the only way that I can really justify that is by making it paid.
Otherwise I won't get up at 0600 to fix an SLA.
Let's see! I've priced it on the cost of an inner-tube a year. So fingers crossed.

I'm working on a charitable donation tracker for taxpayers. My wife and I used Intuit's ItsDeductible for years until it shut down in October. With a little encouragement, I built Charity Record.
The stack is Django 5.2 (I know, I know, I'm looking at 6 now), Postgres, and HTMX + Alpine.js for interactivity. I'm using Polar for subscriptions. It's running on the $12/mo DigitalOcean droplet.
Trickiest parts so far: TXF export (we can trace TXF back to the 1990s...) and PDF generation. At one point when working on PDFs, WeasyPrint was deadlocking a single-worker setup because it fetched the logo via HTTP. (Base64-embedding the logo got me past that, ha.)
Happy to answer questions about the app or running Django lean - I've got a few longer running Django projects.
Have been working on an app to capture thoughts and to make sense of them with a timeline view. Have posted the first version here and got a lot of suggestions so that we continue working and now release an open testing version to play store. If anyone interested in trying please visit

I will give it a try if you give my project a star ;-) https://github.com/adamwong246/testeranto
I’m working on Yomu, an iOS app for reading Japanese text with adjustable furigana.
I’m learning Japanese myself (recently took JLPT N4), and I noticed that full furigana makes me rely on readings instead of actually reading kanji. Yomu lets you hide furigana for kanji up to your level and keep it for harder ones.
It’s offline-first, supports importing text from anywhere, camera OCR, and a fast dictionary.
https://yomuapp.kulman.sk
https://wordcollector.netlify.app An offline dictionary in your browser. Dictionary is pulled from the open source wordnet dataset and cached in browser as a sqlite database. Installable as a PWA as well. Working on adding a study mode to review words that you’ve looked up in the past to help commit them to memory and adding synonyms and antonyms. Plans to add multiple languages in the future so you could use this as a language learning tool as well.

I just finished building my own IoT platform and I’m honestly so proud of it.
It’s completely free. Please try it out it would mean the world to me! Would love some feedback.
N.B. Finished the landing page and docs this morning. Done I’d better than perfect so expect some rough edges.
https://micro-arcade.netlify.app/
I have been making a micro-arcade of one button games using a fun little library I found.
It is so fun to just have an idea and implement it in under an hour or two. It is a great creative outlet.
Give them a play if you have a second, they are very rough around the edges but are playable on mobile or browser.

Trying to make my Rust library `composable-indexes` more ergonomic. It is for indexing a collection on multiple dimensions in a type-safe and composable manner.
In other words, something safer & more concise than maintaining multiple HashMap's, but a lot less involved & simpler than an in-memory SQLite.
It's better explained by the example here: https://github.com/utdemir/composable-indexes/blob/3baa36762....

I've been working on the same business since 2021:
https://notionbackups.com
The first business I started never gained traction, so I sold it in 2021 (which was a completely different time compared to now).
Notion had announced that they'd launch a beta version of their API, so while waiting for the early access, I built a landing page, login/signup, and all other plumbing for the web app.
It was a rather underwhelming launch (both for the API and my business), but I gained my first customer within a month.
Honestly, it's been a slog running this business (Notion's API is surprisingly hard to work with, so it seemed that I was stuck for months on end), so knowing what I know now, I'd probably have started a different business. My burnout didn't help either.
Claude has been incredibly helpful these last few months in solving esoteric undocumented edge cases that were plaguing the codebase for years.
I have a healthy MRR/growth rate right now and the biggest product in the niche, so I'm grateful for that.
I’m working on Universymbols, which lets you restyle icons to match your app’s icon set, like SF Symbols, Material Symbols, and many more.
It uses a pipeline involving several AI models, including Nano Banana and OpenAI’s gpt-image-1 for the raw image generation.

Currently doing the finishing touches on a ww2 era surface grinder, closing out a new little design, and ramping my fitness up again. Next up is some duct work, some reverse engineering, and finishing my part of a paper.
I haven't had this much time off in over a decade and it's amazing. I've been hoping to get inspire for some outdoors or running related mechanical design/prototyping projects, but nothing yet.
Feels like I'm working on a million things (between work, side contracts, and creative explorations). Recently a friend asked whether AI is helping or hurting my workflow.
And I realized I couldn't give a concrete answer. Lots of speculation, but I realized I didn't have hardly any real data. Inspired by Adam Grant's work on "rethinking", I'm _currently_ writing a tiny CLI to run self-experiments on my own productivity, auto-checking in / observing commits/code changes.
Goal at the end is to be able to test myself across different dimensions with "no AI", "moderate AI" (e.g. searching, inline assist), and "full AI" (agents, etc). https://github.com/wellwright-labs/pulse
Working on a flight tracking tool that records the landing and takeoff actions of a local airfield to get insights in how they determine on which runway a takeoff or landing is assigned. Problem is that all the free aircraft api's don't register a landing or takeoff act and also not on which runway.
The airport in question has just one runway and is situated in a dense population area. Both sides of the runway are used (officially noted as two runways) for takeoff and landing causing noise complaints in the neighborhood. The airfield says it assigns a runway based on wind direction and speed, and when there is much traffic they relieve one of the two directions to prevent going over a threshold. My goals is to check if they follow their own rules and just to have a insight if my annoyance over why there are so many aircraft over my house and not on the other side is justified or not.
As a frontender this is quite challenging. I'm using Express with typescript to write the backend. Usually I get bored quite quickly because progress is not going fast enough, so I'm using a lot of AI to speed things up.
I'm checking for aircraft in a 5km circle every 30 seconds. If a aircraft is below and above x feet than I'm going to track it every 5 seconds. Between each entry I'm checking the coordinates and altitude to determine which runway (direction) is used and if it's taking off or landing. I'm also using another API to get weather data like wind speed and wind direction. Finally this is saved in a JSON file (for now) and loaded into the frontend to be displayed in a table.
I do have a working prototype, and removing a few bugs. At the moment it's checking the logs after a day of collecting to check for errors, fixing those errors and validating the fix the next day. When it's done I'm planning to open source it so that anyone can use it if needed.
I've really enjoyed writing blog posts recently. Not only is it a great way to flex your writing muscles, but writing about a topic, unsurprisingly, helps you understand that topic better too. I've had great conversations with friends about the posts I've written as well.
And sort of in that same vein, I've been developing my own static site generator that I eventually want to move my blog to. It's almost certainly going to be a worse SSG than every alternative, but it'll be mine and that's worth something in itself.
Plus it's just been fun to make! I wrote some gnarly code to generate infinitely nestable layouts that I'm kind of proud of. It's the kind of code that's really cool but you can only code on a project for yourself, because if someone else had to debug it, they might say some pretty unkind things about you.
I agree with you about writing. Back in 2020, I made a commitment to study a CS or math topic in detail each week and then write an essay about it. Those were some of my best learning experiences and when I look back at those essays, they are pure gold.

I crunched Strava data (the Strava MCP project is incredible, and I ended up contributing to it!) and built myself this fitness hall of fame page (and also rejuvenated the remainder of the portfolio). Almost all of the stuff here is vibe coded, very happy how much I could achieve.
i saw the strava mention and I clicked through - this is a super cool project! The maps + visualizations are beautiful.
Something about strava and the data we get from it is really special to me. It's a fun step into a deeply physical thing (moving our selves around the surface of the earth) and renders it in this digital space - a website, an animation.
Working on The Password App (https://thepassword.app) - an AI-powered macOS desktop app that automatically rotates your passwords across websites.
The problem: most people have 100+ accounts with weak/reused passwords. Changing them manually is tedious, so nobody does it.
The solution: import a CSV from your existing password manager (1Password, LastPass, Bitwarden), select which accounts to update, and the app uses browser automation with Gemini 2.5 Flash to navigate to each site's password change page and update them in parallel. Exports a CSV with the new passwords to import back.
Key technical choices: - browser-use library for AI-driven browser automation (handles dynamic sites better than Selenium) - Local-only architecture: passwords never leave your machine, no cloud sync, everything stays in memory and is cleared after use - Electron + Python: React frontend with a Python agent for browser automation via stdio IPC - OpenRouter for LLM access (Gemini for navigation, Grok for validation)
Security was the most important and the hardest constraint. Passwords can't be logged, can't be sent to the LLM context, and can't persist on disk. Custom fork of browser-use to inject credentials via secure parameters invisible to the AI agent.
Currently at v0.38 with code signing and notarization for macOS. Working on improving success rates - the main challenges are 2FA requirements and anti-bot detection (Cloudflare, reCAPTCHA).
Would love feedback from anyone in the security/password management space.
https://github.com/Mockapapella/tenex
Tenex, a TUI for managing swarms of AI agents.
I noticed that as I'm using agents more and more my PRs are getting more ambitious (read: bigger diffs), and when I was reviewing them with agents I noticed that the first review wouldn't catch anything but the second would. This decreased my confidence in their capabilities, so I decided to make a tool to let me run 10 review agents at once, then aggregate their findings into a single agent to asses and address.
I was using Codex at the time, so Tenex is kind of a play on "10 Codex agents" and the "10x engineer" meme.
I've since added a lot of features and just today got to use it for the first time in a production system. Some rough edges for sure, but as I'm using it any time anything feels "off" or unintuitive I'm taking notes to improve it.
Fun fact, on my machine, while launching 50x Claude Code instances very nearly crashes it, I was able to launch 100x Codex instances no problem. I tried 500x but I ran into rate limits before they could all spawn :(
I find that absolutely terrifying, but I wish you luck.
Getting close to my last day at my current job, and I couldn't be more excited to build in public.
When I moved to Thailand last year, the language barrier hit me immediately. So I’m scratching my own itch and building https://thaicopilot.com/, It's designed to help you learn Thai in real situations. Still early, but moving fast.
I'm migrating my current Google Sheets solution to a web application that I will primarily use for expense tracking and budgeting. I'm learning Golang so this is a perfect opportunity for me to build something meaningful.
Two main aspects will be to do Exploratory Data Analysis and to forecast expenses.
For later stage, I am planning to create a conversational interface for the application that I will use to do basic CRUD operations as well as capability to "talk" to my data and to do simulations using hypothetical yet real scenarios in future.
I’ve made AI browser that others do but having full control.

It was my weekend 1-day hackathon yesterday building Electron-based web browser connected with PlayWright MCP and local Codex as LLM backend.
Yes, you need to be ChatGPT Pro+ to use, because Codex has no usage fee unlike API Key.
GPT-5.1-Codex-Max can handle really complex web task without templating DOM. Codex-Mini is fast so you can pick models. It does my job applying task to any of recruiting sites with no interactions. (with persistent data store, which is currently disabled on published version)
Today is the start of Langjam Gamejam, a 7-day hackathon to build a programming language and then make a game using it. I'm ideating on what I'll build.
https://news.ycombinator.com/item?id=46097671
An Obsidian plugin that makes life tracking easier: https://www.dsebastien.net/announcing-life-tracker-a-new-obs...
Working on promptfoo, an open-source (MIT) CLI and framework for eval-ing and red-teaming LLM apps. Think of it like pytest but for prompts - you define test cases, run evals against any model (OpenAI, Anthropic, local models, whatever), and catch regressions before they hit prod.
Currently building out support for multi-agent evals, better tracing, voice, and static code analysis for AI security use cases. So many fun sub-problems in this space - LLM testing is deceptively hard.
If you end up checking it out and pick up an issue, I'll happily send swag. We're also hiring if you want to work on this stuff full-time.

I've been building out my portfolio at https://verdient.co.uk/ and writing more blog posts about applied maths on my blog at https://tom-dickson.com/
Most recently I've been having fun extending the functionality on a website I use to host tools that help me structure and plan workouts - https://ironvolume.com/
I’m speed-running a bunch of new hobbies to teach myself how to make a physical game (basically its a ping pong paddle that tracks how often you hit a ball — like a “keepy uppy” game with scorekeeping):
- Arduino dev and circuitry
- 3D printing
- PCB design
- Woodworking
Its all a lot of fun and IMO a lot more approachable than it has been thanks to the assist from LLMs.
Trying to rebuild my website (php mvc built a decade ago) using Django. I want to be able to update any page content, upload and display images, have multiple blog instances. I do a lot of django-cms by day, but it's too much for a small personal website, so I started to create a (tiny, foss) CMS based on Django, django-prose-editor for the content, and some new apps (for now, Page & Blog).
The site isn't even online, but for now I'm starting to think about the next steps (seo-related things to implement, generalize app functions to handle not only blog but other (hypothetical) apps as well, improve code quality and repo readability, separate apps from the website so anyone can add them to their django website if they want to). It's a lot of work for something no one will ever use, but I must at least try to make it clean and discoverable :)
I've been working on several internal tools that act like extensions for the django admin.

Both of these are super cool. So many times in the past I could have used the redis one!!!
As a means to learn about both WebAssembly and Rust, I started writing a WebAssembly binary decoder (i.e. a parser for `.wasm` files) from scratch.
Recently it hit v2.0 spec conformance. 3.0 is next on the roadmap. (I'm executing it against the upstream spec test suite.)
I don't plan to make it a highly-performant decoder for use in production environments, but rather one that can be used for educational purposes, easy to read and/or debugging issues with modules. That's why I decided not to offer a streaming API, and why I'll be focusing on things like good errors, good code docs etc.
https://github.com/agis/wadec
P.S. I'm new to the language so any feedback is more than welcome.
This is cool.
I started to look at the wasm stuff, but all the documentation I found was so high-level as to be meaningless.
What do you recommend for someone who would want to be able to create or read .wasm files?
I'd say jump straight to the specification (maybe v2, which is simpler).
But I occasionally saw one or two articles around where they explain how the binary format works, which could be a good introduction before jumping to the spec.
Thanks!

Working on https://canine.sh, an open source, self hosted PaaS for Kubernetes.
A big part of this was inspired by the last startup I worked at. In an effort to not deal with complexities of Kubernetes, we ended up on Heroku and was charged exorbitant amounts of money. One year spending close to 400k on Heroku alone, for what should’ve been 10-15k in cloud costs.
I think a big part of this is just making Kubernetes more friendly and easier to use for a small / midsized team of developers.
The goal is to make it easy enough for even a single developer to feel comfortable with, while also being powerful enough to be able to support a small team
I see that your app/tool is linked on Portainer's website. What's the business model behind it ? I do not see any pricing and I could be really interested as I'm looking for a solution to abstract away k8s complexity for a medium sized company I'm working for.
Yeah it’s totally free to use and there are pricing tiers for support that portainer provides. Canine is 100% FOSS. No hidden features behind some payment plan or anything.
Portainer sponsors us, to keep us working full time on it.
Shoot me a note at chris @ canine<dot>sh
Would love to help in any way I can! Always looking for more adoption, esp at medium sized companies
I've built a web app primarily for my Hiking Club but then my plan is to also sell it to others.
https://mojtim.ba/en/
'Vibe coded' this in about a week recently. The app is also available in English and has a demo account available.
I wrote about the building process on my Linkedin (https://www.linkedin.com/feed/update/urn:li:activity:7404469...)
https://playwriter.dev
A browser automation Chrome extension and MCP. It consumes less context than playwright MCP and is more capable: it uses the playwright API directly, the Chrome extension is a CDP protocol proxy via WebSockets.
I use it for automating workflows in development but also filing taxes and other boring tasks
CtrlAssist – an open source project to bring more accessible, collaborative gaming to Linux! Inspired by PC gaming sessions with my own family, where both young and old relish exploring rich stories with immersive worlds (like Witcher 3, RDR3, Hogwarts Legacy, etc) but find coordinated combat or movement control too challenging to play solo, CtrlAssist lets you combine multiple controllers into one virtual gamepad, much like assist features on dedicated game consoles.
https://crates.io/crates/ctrlassist
Whether your helping grandparents through tough boss fights, or co-oping with nieces and nephews to level age gaps, CtrlAssist aims to make PC gaming on Linux fun and accessible for everyone. While I’m certain similar utilities exist, I also just wanted a holiday hobby project to practice Rust development while scratching a personal itch.
Please give it a try, share your feedback in the relevant discussion categories, or check out the open issues if you’d like to contribute, help is always welcome!
- Developer Feedback and Rust Community Discussion
- User Feedback and Accessibility Community DiscussionI am working on Correctify's Design Studio, a feature that turns plain restaurant menu text into menu designs based on your choosen size, style and branding.
What makes it different from alternatives is that it’s content-first. Instead of dragging boxes around or fighting templates that don’t fit your menu, Design Studio designs around your text. For restaurant owners, that means significantly lower waiting times and costs.
Design Studio is still in private beta, but excited about where it’s going

I’m working on OpsOrch(https://www.opsorch.com/), an open-source orchestration layer that provides a single API across incidents, logs, metrics, tickets, messaging, and service metadata.
It sits on top of existing tools like PagerDuty, Jira, Prometheus, Elasticsearch, and Slack, and normalizes them into a shared schema. It doesn’t store operational data, it just brokers requests through pluggable adapters and returns unified structures.
The motivation came from incident response workflows that still require hopping across multiple vendor UIs and APIs with different auth models and query languages. Instead of another “single pane of glass,” this is meant to be a small, transparent glue layer.
On top of the core service, I’m also exposing everything via an MCP server so LLM agents can query incidents, metrics, and logs as typed tools without needing vendor-specific knowledge.
Currently open source, written mostly in Go and TypeScript. Still early, but usable with PagerDuty, Jira, Prometheus, Elasticsearch, Slack, and mock providers. Feedback from SREs and infra folks has been very helpful so far.

How can I train an AI on me doing sensitive work.
I'm building out a new concept around training AI computer use agents on real sensitive tasks without PII exposure. My first demo releasing soon is a dataset of AI agent with human assisted tasks on things like paying my personal credit card or doing bank transfers.
Main things: 1. I don't modify the website I operate on 2. I take full videos and record all AI agent logs and all human actions 3. I don't modify any of those logs and will release them to the public.
I am working towards a future where AI companies are paid to generate the data they need for AI agent operations instead of paying massive sums to generate synthetic data. Imagine a future where labeling companies are completely sidestepped by simply training on production tasks directly.

An agentic media player, intended as home media server for.. uhh.. seasonal vacation videos with subtitles. I've experimented a lot with different "levels" of AI automation, starting from simple workflows, to more advanced ones, and now soon to fully agentic.
Pretty good practice project! All written in Go with minimal dependencies and an embedded vanillja-js frontend built into the binary (it's so small it's negligable)
Hey all, I am a noob at building my own things. Recently, I have started building my own web app, which collects AI related news worldwide. I also cluster them to identify trends within the AI economy. This was interesting to me as I do actively invest in stocks. The website also generates a newsletter, collects details related to new corporate deals announced, etc. It is collecting everything related to AI and the economy.
Now I feel lost, I don’t know where to go from here. I don’t even know if I am doing the right thing. What do you think? Is there any guidance or roast you can give? Here is the website https://www.racetoagi.org/
Here is the trends collection https://www.racetoagi.org/trends
Here is the deals graph https://www.racetoagi.org/deals

A tool for searching, filtering and chatting with the "What are you working on?" posts. Also has a visual map (UMAP) that clusters similar things together. Useful if you want to find specific things or better understand themes.
Cool thing, maybe we can combine these :) https://news.ycombinator.com/item?id=45838592
Working towards a handheld computer with a physical keyboard. Lots of examples out there (Hackberry Pi, Beepy, etc) but wanted to try my hand at it.
Along the way I found most of these use salvaged BlackBerry keyboards which are only going to become harder to find, so also on a bit of a side quest to build a thumb-sized keyboard from scratch. Got me into laying out and prototyping my first PCBs and learning about how these things are made - lots of fun so far!
Something cool I learned from tearing apart a BB keyboard: the satisfying “click” is just a tiny metal dome that pops and completes the circuit when pressed. Not news to anyone familiar with electronics manufacturing, but it was a cool thing to “discover.”
Working on a browser extension that let's you take notes right on youtube.

A service that allows you to post generic agent/task workload and execute and observe it in the background. Sort of for long timelines. I just want to have background agents to monitor various aspects of my digital life and keep those healthy, eg check if I’m using all of the tax credits and leverage them to get the most after tax cash, or constantly monitor my network and alert me when something is off, or scan and evaluate my public contributions and remind to post something new once in a while. Just a tool to make sure I am on top of everything.
Using Go on the back, React for ui, sqlite, containers for async work, openai. Trying to keep it simple.
Been casually working on some AI projects lately. Open-sourced both: LLM Archive Downloader. Got paranoid one night about open-source models potentially disappearing (licensing changes, restrictions, who knows). So I built a script to download and archive them locally. One command, pick what you want — Llama, Mistral, DeepSeek, Whisper, the works. ~200GB total or grab the essentials (~40GB). Now they're sitting on my hard drive. Offline forever.
→ github.com/Ashwinsuriya/llm-archive-downloader
YouTube Shorts Generator Converts long YouTube videos into Shorts automatically. Whisper handles transcription, LLaVA analyzes frames to find interesting moments, Mistral picks clips and writes captions. Everything runs locally in a parallel pipeline. No APIs, no subscriptions. → https://github.com/Ashwinsuriya/yt-shorts-generator Nothing fancy.
Just scratching my own itch and sharing in case anyone finds them useful.
Working on Tenderlane: https://tenderlane.app/
Freight forwarders spend days or sometimes even weeks understanding and answering tenders without even knowing if they'll win the bid!
With Tenderlane, they can now upload the entire tender spec and get an overview of what the customer wants in minutes instead.
One key learning for this project is that I'm using Excel as the "frontend" as this is what our users are most familiar with, so lots of processes involved filling, uploading and downloading an Excel file.
Building this with Elixir/Phoenix LiveView.
I'm finally wrapping up a little webdav tool that's been on my todo list for years. It's just a simple tool to copy directories over webdav. I tried using Cadaver but I kept running into strange errors with it. And this one ties in with an unusual authentication setup. Might open source it, haven't decided yet.
Also dicking around with DMARC tools. Was unhappy with all the existing tools, want something simple I can run semi-locally for a bunch of low volume email domains. Haven't decided yet how that will turn out, still in the reading specs & tinkering stage.
> Also dicking around with DMARC tools. Was unhappy with all the existing tools, want something simple I can run semi-locally for a bunch of low volume email domains.
That’s a rabbit hole on my list to go down - recently set up DMARC for some domains I am hosting emails for and the XML reports that now end up in my inbox were… refreshing to see in 2025 :)
Some recent tools, finished/improved this year:

Currently, I work on a Desktop GLSL shader editor. Looks fine so far...
I’m trying to build 1 decent iOS mobile app per month.
Most recently released one was My Vocab Quest[1], a vocab mastery app with lots of word packs. It uses some gamification mechanics to make sure the user puts in the reps.
Current apps in the hopper are centered around:
(1) Recovery from cosmetic surgery. There are several balls to juggle for days, weeks, and months after a surgery. The app helps the user follow surgeon instructions, promoting physical and mental recovery, as well as medical and dietary changes. Makes use of phone features including contacts, calendar events, notifications. I’m learning to build an App Clip for it and hope to partner with some surgeons to get it promoted in their offices.
(2) Assisting older Americans to be more independent for a little longer (a parent of mine has early stage dementia). Helping the user maintain a regular schedule, take their medications on time.
(3) A dating ideas / meal ideas and agreement app. It helps increase creativity for date ideas, learns from how predictable you are, and facilitates agreement between the users.

Eidetica - a decentralized database built in Rust, intended for local-first apps. It's still unstable but I'm progressing relatively rapidly. In the past ~month I have:
- Flown to SF to attend a conference in this niche: https://syncconf.dev/
- Added password based, transparent, end-to-end encryption
- Improved my custom CRDTs
- Added an index to store configs and metadata
- Built support for using sqlite + postgres for Eideticas backend (not pushed yet)
Once I finish the backend work I'll hopefully take a bit of a break though. I'm supposed to be retired.
Last night I decided to take a break from the digital world and started on making a guitar. Leaning towards something in the style of Lacôte[0] but not sure, ordered a book on Vicente Arias[1] and might order a couple other plans to consider. Have a fair amount of stock prep to do before I have to commit to a design and will probably need to order a few sticks of wood as well, so probably have ~two weeks to make up my mind.

2) Katalib.
We have about 1600 books or so at home, there's no chance I'm going to scan ISBN codes of all of these. I've tried four times and got way too bored after the first 100-200. The solution? Take a photo of the bookshelf, send to Claude for text parsing and series information. Then some UI etc around that.
It's working, I just need to start testing it myself and a few friends have also asked for access.
I'm starting the process of photographing everything I own for a potential insurance claim in my high wildfire danger area. I've dreamed of something like this that could name, describe, and estimate the replacement cost of each item, saving me hundreds of tedious hours. Including books. So please think big like Jeff Bezos and don't stop with books.
If visions of wealth don't motivate you, think of how much the insurance companies will hate it.
Huh, interesting. I hadn't considered that. Do many people in your area photograph their things?
Dunno. But "itemize this photo" has tons of applications.
I am not really working on anything big right now, mostly just improving what I wrote, in particular documentation-wise.
However had, on my todo list ... a few things that are important to me are there.
One is to create some kind of pseudo-language that can model biological cells, from A to Z. I am having something similar to erlang in mind (to some extent). Now, this is nothing new - modeling is quite old, bioinformatics is old, but I have a few ideas that are somewhat novel IMO (e. g. really following erlang here, just adapted to biological systems).
Then I have a few smaller ideas. One is to finish a webframework where everything is really an object at all times. Meaning, I can work with objects when describing a webpage, from A to Z. HTML tags are objects too. I don't typically use them directly, though, but more in a meta-layout, e. g. I want to describe a webpage, but on a higher level, and also push that down into a .pdf file then seamlessly. My goal here is to be able to work with objects everywhere, not just for a single webpage but for all local and remote webpages, a bit similar to Alan Kay's old ideas.
I have a couple more ideas (one is the widgets project where I want to describe a GUI only once and then have it work in as many variants and languages as possible), but realistically I also focus on the smaller things to do as they are much easier to solve. Right now it is more important to me to finish as much as possible before the end of the year, so prioritising on smaller things makes more sense.

I've recently been working on developing an MCP on top of Libreoffice Draw and I just learned what an amazing piece of software the whole Libreoffice suite is, I would definitely be trying to use it more and I will take a look at your extension. Thanks for sharing!
It is! My only struggle is with the extension development/documentation. It was a pain to get my sidebar appearing in the toolbar, and I'm afraid to touch any of that code I wrote.
How are you going about learning about the LibreOffice APIs?
nice!
Building Arivu: CLI/library that normalizes fetch/search across a bunch of sources (arXiv, PubMed, HN, GitHub, Reddit, YouTube transcripts, RSS, web pages…).
I use it as a context fetcher i.e grab an abstract/transcript/thread as clean text/JSON, pipe it into summaries or scripts.
Also runs as an MCP server (experimental), so tools like Claude Desktop or CLI assistants can call the connectors directly.
https://github.com/srv1n/arivuJust tried it, this is going to be super helpful with Claude skills.
Nothing on the scale of most the things mentioned here, but I'm trying to assemble the first version of my digital garden to publish online a bunch of notes I've collected over many years. I'm also trying to put together a workable system to catalogue and index hundreds of thousands of digital images scattered across multiple devices so I can deduplicate them and collate them effective. Digital Librarian is not a hat I ever thought I'd end up wearing, but I refuse to buy more 18Tb HDDs and still not have any means to locate pictures in a meaningful way.

Trying to grow this newsletter - a roundup of the most votted and commented AI links from HN. After 11 issues I am at 221 subs, most of them from Reddit posts (I post a short description of the top 5 links on several AI subreddits). Not sure how long this will work, I feel like I spam these subreddits.
I want to launch on Product Hunt soon and maybe add it to some newsletter directories, but I have low expectations.
I post here on HN a link to each issue after I send it, maybe that will get from traction one day.

I've been working on a weightlifting logging app for the apple watch. I haven't submitted it yet since I am still beta testing, but I'm mostly feature complete.
It's intended to be anti-memetic, and anti-guilt trip. Just put it on your watch, install a program (open format) and you never need the phone itself. Your workout is a holiday from your phone.
The data can be exported if you want to use it elsewhere.
I originally made it for ROCKNIX but as there was no way to share the app I paid the Apple tax :/

Working on my language learning app (Python, tkinter) "Xiaolong Dictionary"[0]
It is supposed to implement all kinds of features, that I usually miss in vocabulary learning applications, such as a very powerful search function, and the ability to add arbitrary tags, a table of words, and learning progress statistics (not yet implemented).
It has minimalistic dependencies. Currently the only non-development dependency it has is jsonschema.
I keep the configuration of the application in a JSON file. This configuration already allows to configure many things, like for example the various learn levels, and what their meaning in terms of the spaced repetition system is, which attributes of a word will be revealed in what order, when practicing, what attributes to show in the columns of the vocabulary table, and what font to use for the big character display widget (useful for languages like Chinese).
It's AGPL, so feel free to fork, but adhere to the license.

I'm working on a collection of stackable interactive slides for teaching numerical methods and operational research.
https://okaleniuk.codeberg.page/blackboard/
The idea here is, one can pick the slides they want and arrange them into a sequence right in the URL. This way, there is no registration, no user data collection, no persistent state even. You just pick the slides, teach your material, and move on.
It's very raw, I still want to add a convenient sequence constructor, a "blank" slide so you could display your own content in it, and a similar quiz page. But I already used some of the slides for teaching, students seem to like them.
Hopefully, I'll have the rest done by the beginning of the spring semester.
I'm experimenting to see if frontier LLMs can do practical CAD modeling. I'm starting with a single task: designing a wall mount for my bike pump in OpenSCAD or CadQuery (two code-based CAD systems).
None of the frontier LLMs (Gemini, ChatGPT, Claude) produce usable designs when just prompted with some photos of the pump and a written description of the mount. I'm now building a simulator in Mujoco that the LLMs can use to test and iterate on their designs to see if they can do better in this setting.
I'm hoping to make an interesting blog post of it and maybe end up with a usable wall mount design.

I’ve been working on Pixie, a platform to employ and track your kids for real work; for families with a business, it helps reduce tax burden and fund a child’s Roth.
I’m actually an anesthesiologist with some 1099 income, built the platform myself because my kids help with my side projects, and have since onboarded CPAs who now offer it to their clients. It's been a fun journey!
I've been spending weekends thinking about authorization for AI agents, specifically delegation.
The failure mode I keep hitting: once you give an agent tools, it gets ambient authority over all of them. There's no clean way to say "for this task, read-only on the reports table" or "spin up no more than 3 VMs." When the agent spawns sub-agents mid-execution, they inherit full access by default.
IAM doesn't help much. Authority stays tied to the agent's identity even as intent shifts during execution.
I'm exploring a capability-based model instead: authority is explicit, task-scoped, and attenuating. Closest to Macaroons/Biscuit, but adapted for workflows where delegation happens dynamically mid-task.
Early prototype (Rust core, Python SDK, LangChain integration), still thinking it through. Notes here: https://niyikiza.com/posts/capability-delegation/
Excellent article, and I fully agree.
I came to the same realization a while ago and started building an agent runtime designed to ensure all (I/O) effects are capability bound and validated by policies, while also allowing the agent to modify itself.

I'm working on a meta framework for building "full-stack" libraries. I.e. libraries that bundle frontend hooks, backend routes, and a database schema into a single package.
This allows library authors to do more, like defining webhook handlers and (simple) database operations. The idea is to move complexity from the library user to the author, making (API) integrations easier.
I think libraries being able to write to your database is a pretty powerful concept, and can enable a number of interesting use cases.

I made a platform for innovators, founders, developers to validate their idea against real users (not AI).
My purpose to build this platform is two-pronged–first to solve the "Power Law", in simple terms, where platforms such as Instagram, Reddit, YouTube, TikTok, etc. only put forward the popular content (most upvoted, liked, viewed, trending, etc.) and people who are posting regularly are still left behind fighting for some interactions.
Second, to provide a platform for people, innovators such as myself, who keep asking the question "is this worth working on? worth spending time and money on". There are subreddits with hundreds of thousands of followers and Redditors and many of them are still not getting the visibility they need to start.
I remember that I had a lot of ideas throughout high school but I wasn't able to get real answers and validation from people so I dropped it. So specially for those people who need a little bit more visibility.
So trying to solve that.
Several years ago I wrote an internal tool named Fogbeam Universal Competitive Inteligence Tool (eg FUCIT). It was up and running and doing it's job for a while, then a lot of stuff happened and it kinda fell into disrepair. It's a Grails app and the original Grails version was something like 2.2.3 and I think it was running on Java 1.6 or something along those lines.
Anyway, for a lot of reasons that don't matter now, the time has come to rebuilt | reinvent | reinvigorate this thing. So for the last week, I've just been working on updating dependencies, fixing the resultant breakages, and also fixing miscellaneous bugs that had never been fixed (or possibly even noticed) before.
As of today I have most of the base functionality up and working again. I just got all the Quartz scheduling stuff set back up and now I'm testing the scheduled job that fetches data from RSS feeds and creates associated records based on the contents of those items.
Up next: test|fix some functionality around defining "semantic assertions" about entities in the system (using Apache Jena) and then I'll at least be back where I was.
After that, I have some UI improvements to make (the UI now is basic GSP pages with Bootstrap and jQuery), and then some GenAI integration stuff. Beyond that: who knows?
Besides that...
Ref this thread: https://news.ycombinator.com/item?id=46252283
I did pick up Volume 1 of "The Handbook of Artificial Intelligence" earlier this afternoon and read about 25 pages. I've also been working my way through "Parallel Distributed Processing - Volume 2" and "Principles of Semantic Networks" for the past few weeks, so continuing to grind on both of those as well.
A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use. There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used. When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.
My Civil 3D plugin will:
1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.
2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.
If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.
As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.

I've building PaaS focused on development environments. I think there are so many things to be improved all throughout the development process:
1. starting from creating new ones
2. forking existing one (like one would do with the git repo) to experiment with new ideas or debug the issue in an isolated environment
3. being config defined and reproducible
4. hybrid by default - run as much or as little one desires on their personal machine while keeping rest of the env (db, storage, ...) in the cloud
5. easy to share: expose services (HTTP/TCP/UDP) on public or private networks
6. have any number of AI agents with specific goals be part of the dev env

I'm building https://aero.zip, an E2E encrypted, resumable file transfer tool (think WeTransfer but encrypted and not P2P). I just posted it to Show HN:
https://news.ycombinator.com/item?id=46262540
A few technical details I enjoyed working on:
* Streaming ZIP: To allow downloading multiple files as a single archive without buffering, I implemented a custom streaming ZIP64 archiver. A Service Worker intercepts the request, fetches encrypted chunks, decrypts them, and constructs the ZIP stream on the fly in the browser.
* OPAQUE auth: I used the OPAQUE protocol (via serenity-kit) for the password-authenticated key exchange. It ensures the server never learns the password and protects weak passwords against offline attacks if the DB leaks.
* Passkey PRF auth: If your passkey provider supports PRF (like iCloud Keychain or Windows Hello), the app derives the data encryption key directly from the passkey, allowing a login flow that doesn't require entering a master password.
How is it different from croc?
From what I understand, croc is P2P, i.e. both computers have to be on for the transfer to happen (the "relay" that they mention only helps negotiate the connection between two peers). With aero.zip, you upload your files to a server, and the recipient can download it whenever - either real-time while you're still uploading them (imitating the P2P/croc model), or at a later date. This is a more universal approach IMHO.
Also, aero.zip is a webapp, i.e. there's nothing to install, and you don't even need to sign up to send small files. Meanwhile, croc is a CLI utility which will be hard to use by mom-and-pop users.
Got it. Is it safe to say that aero.zip is closer to wetransfer than it is to croc?
I’m working on a small browser extension called Instant Preview.
https://chromewebstore.google.com/detail/majhgbekihmliceijip...
It lets you open links in a side panel, so you can quickly look at a page without leaving what you’re reading. I built it because I tend to open too many tabs when reading docs or search results.
It supports a few simple triggers. My favorite one is long-click: you click and hold a link, and the preview opens in the side panel.
Chrome recently added Split View that you open from the context menu. It works, but for quick checks it feels a bit heavy. You have to right-click, move the mouse, and pick an option.
With long-click there’s no menu. For me it feels faster, more intentional, and better when scanning lots of links.
Most of the work lately is about polishing these interactions and dealing with browser edge cases.
Hey all, I am a noob at building my own things. Recently, I have started building my own web app, which collects AI-related news worldwide. I also cluster them to identify trends within the AI economy. This was interesting to me as I do actively invest in stocks. The website also generates a newsletter, collects details related to new corporate deals announced, etc. It is collecting everything related to AI and the economy.
Now I feel lost, I don’t know where to go from here. I don’t even know if I am doing the right thing. What do you think? Is there any guidance or roast you can give? Here is the website https://www.racetoagi.org/

Since then I found https://github.com/badlogic/pi-mono and https://github.com/johnlindquist/mdflow and I think I'll rather use these existing tools to explore my idea. But I think it might be still interesting project because it is entirely vibe-coded - I don't even know Typescript (I know some Javascript from before React - but none of the new stuff). I did not look into the Typescript code at all - only at what the LLM presented to me when editing it and the docs. At some point I discovered that when I tried to have a core logic and two UI packages the LLM put only types in the core package - so I had drive a hard refactoring - but it worked.
I haven't yet tried this very extensively - but another profound change in programming that this showed me is that it is now very easy to borrow parts of Open Source libraries. It used to be that you could only base your work on a library - borrowing parts of projects that were not designed to be shared (used as libraries) was prohibitive - but with llms it is entirely possible to say: "now please borrow the UI ideas from project X" and it does that. Maybe you need to add some planning.
The project is about 27kloc now.
I'm working on https://wireplug.org: A simple, free, and open source connectivity coordinator for WireGuard. Basically a way to keep WireGuard tunnels connected while moving between different access points. It handles (basic) NAT traversal and works with the in-kernel WireGuard driver on Linux and OpenBSD.
You can find the technical details at https://wireplug.org
I finished the library providing all features of a multisig file signing scheme. With that it was easy to develop a cli tool. And now I'm looking at developing the server component. Looking forward to share a complete solution! Git backed, decentralized, no account creation needed (auth by key pair), open source and self hostable!

I'm trying to make a neural audio codec using a variety of misguided methods. One I am using ESNs wrong spreading leak rates in a logarithmic fashion acting like a digital cochlea. The other is trying to do the same with a complex mass-spring-damper system to simulate the various hairs of the cochlea as well. Both approaches make super interesting visuals and appear to cluster reasonably well, but I am still learning about RVQ and audio loss (involves GANs and spectral loss). I kinda wanna beat SNAC if I can.
Do you have a log available somewhere?
Reminds me of https://github.com/RobViren/kvoicewalk where people take voice clips and train a text to speech using random walks.
Not related, misguided methods :D

I’m working on a community-driven website for finding local deals, especially happy hours, in Seattle, Washington: https://seattlebardeals.com/. I launched last week on Seattle Reddit and got a lot of positive response. The long-term goal would be to have something like this in every city, so when people are new or are just visiting they can find fun things to do on a budget

Just wrapped up the latest build of Bedtime Hero - an application (React-Native, ios, android) for parents to build/generate bed time stories with their little one. Allows the parent to use pre-sets or set their own and then generate a story (complete with images).
This was a satisfying project mostly because I dog-food it every night with my little one.
Mostly been working on tier6 [0], which is "like" zerotier but over the sanctum protocol and fully open source (ISC licensed).
Getting ready to release a 1.0.0 of sanctum [1], after almost a year of internal testing, dogfooding and talking about it at security conferences.
We've also setup conclave [2] as an official release site for the projects tied to sanctum such as tier6, or the library implementation of the protocol etc.

Started working on an application to make it easy to see what parcels in NYC are upzoned with the City of Yes[1] changes that were passed last year.
I started off trying to make it a service to help people who are interested in ADU's get connected with architects/ contractors but spent a lot of time working on the interactive map to explore related ideas. The site is here buildbound.xyz and map here buildbound.xyz/map. Right now for example, it's very hard to tell if your site qualifies for the TOD upzoning portion of the City of Yes so maybe there is room to crunch those kind of numbers and provide it as a public service.
Trying to decide to keep going down the ADU route in NYC, even though the market is really early here, expand to NY State/ California where the ADU market is a bit further along or keep doubling down on making the best interactive zoning/ land use map in NYC and see if there is any product market fit to be found.

Building https://floxtop.com, a native Mac app that organizes your files.
It looks inside each file to see what it’s about, then moves it to the right folder for you.
Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.
It works in 50 languages (including English, German, French, Spanish, Swedish) and with images (OCR and object recognition), PDFs, Microsoft Office, ePubs, text, Markdown, and many other file types.
If you have messy folders anywhere on your Mac, Floxtop can help.
This looks very interesting and I appreciate the pricing model and lack of cloud. It wasn’t clear from the site, but is there a check all moves prior to execution function? Undo?
There is no automatic execution — nothing is moved without your confirmation.
Floxtop suggests the top 5 destination folders where a file could best belong. You stay fully in control: you can choose one of the suggestions, move files individually or in bulk (Move All), or select a completely custom folder location at any time.
If you change your mind, you can Undo per file or use Undo All to revert the entire operation.

I built Codeboards, a developer portfolio that updates itself automatically from your GitHub, StackOverflow, LinkedIn, and more. Most dev portfolios are outdated, manual, and painful to maintain. GitHub alone doesn’t show who you are. LinkedIn is noise. Personal websites die after 6 months.
I’m working on a modern transactional email API platform. Developers can bring their own AWS SES keys and freely use their own domains for sending emails.
I’m building it on Cloudflare Workers with advanced tracking, modern templates, and advanced webhook integration. Developers can also configure and schedule advanced workflows for their specific needs
The users can review their usage and performance using an intuitive dashboard.
Email is a crowded space and this is my first attempt at doing something indie at this scale. Wish me luck!
Sounds interesting, are you also thinking about inbound email?
Inbound emails using AWS SES make sense, but not planning that as the part of the MVP.
Is that a commonly requested use case for AWS SES users?
Good luck!
Working on turning individual disparate services into a unified zero-trust overlay network (what we're calling a Synthetic Environment™) where mocks and real services can be integrated or work seamlessly together, accessible through traditional networking or exposed public tunnels.
This is a developers tool, that can be used during development to seamlessly integrate mocks and changes into existing systems. Or easily expose internal work through a public tunnel. Or if been in an position where its hard to push to staging, pre-prod or other environments because of many competing constraints, then this product may help.
Working on https://ottex.ai/ - BYOK alternative to Wispr Flow and Raycast AI shortcuts.
I love global voice-to-text transcription (especially when working with Claude Code or Cursor) and simple AI shortcuts like "Fix Grammar" and "Translate to {Language}".
I realized I was spending around €35/mo (€420 a year) on two apps for AI features that cost just pennies to run.
So I built Ottex - a native macOS app with a tiny footprint. Add your OpenRouter API key and get solid voice-to-text using Gemini 2.5 Flash, plus any OpenRouter model for AI shortcuts.
I've been working on a personal project, from absolute zero to marketing, and it's been a great journey.
Mastering interviews and the most common questions, practicing all the questions to ace them, of course with AI and a lot of language chaining. Real time feedback, complete analysis of interview too. https://intermock.com
Volatility Regime Prediction via Causal Discovery in Option Markets - https://github.com/philippdubach/vol-regime-prediction/blob/...
Volatility regime models (Markov-switching GARCH, regime-switching stochastic volatility) are ubiquitous in finance. However, they share a fundamental limitation: regimes are identified ex post from return dynamics, providing no predictive power for regime transitions. The standard approach fits a Hidden Markov Model to returns, labels high and low volatility states, and estimates state transition probabilities that are essentially unconditional averages. This matters because the economic value of volatility timing depends entirely on predicting regime changes before they occur. A model that identifies regimes only after observing the returns is useless for trading volatility.
Existing research documents regime-dependent behavior but does not identify causal drivers of regime transitions. The papers on volatility forecasting factors, variance risk premium dynamics, and market instability from option flows dance around this question without directly addressing it. The recent work on causal ML in finance (double machine learning, causal forests) has focused primarily on equity return prediction rather than volatility states. The connection between options market variables and subsequent volatility regime transitions has not been rigorously established through causal methods.
We develop a causal framework for volatility regime prediction using option-implied variables as potential causes of regime transitions. The key insight is that options markets are forward-looking, so information embedded in the implied volatility surface, put-call ratios, option order flow, and term structure slopes may causally influence future realized volatility regimes rather than merely correlate with them.
Currently building a robust dataset.
My biggest project is still Materia[0], a tool for deploying applications with Podman Quadlets. This month I presented it to the Podman User Group's community meeting, which was pretty exciting since I've never presented in a community setting like that before. Otherwise I've been trying to focus on bugfixes, minor feature additions, and working with user feedback so it's not just me fixing my own problems :) . The latter is really fun since I've already run into someone using it in a way that's very different than how I'd imagine it.
Not coding related, I've been on what I've been calling "The Grand Project" for a bit over a year now where I listen to every single album I own (around 855 albums/singles/eps/etc. As of this moment I'm at 828) at least once. It's been a real trip essentially going through my whole life musically and I'm hoping to write a blog post somewhere about it.

I've spent several years solo-developing an ad-free website with over 50 different solitaire/puzzle games:
https://inSolitaire.com
I've rewritten this project (almost) completely three times and now doing it for the fourth time, with tests and best practices.
I would be incredibly grateful for any feedback what I'm missing with it.
So far it has been great fun and I have learnt an incredible range of things!
This is _very_ smooth and really well done. I've only played a bit of the Solitaire but it's really nice on both desktop and mobile.
I'm curious why you're rewriting it for a fourth time? Am I playing version 3 or 4 right now?
Two potential suggestions:
1. You save the game on pause / tab close, it means I'm not able to continue from another device. Would it be possible to provide some form of "seed" that I could input in my other device to continue where I left off? Not sure if that's even possible, just an idea.
2. Option to toggle between mobile/desktop style cards. I understand the desktop style ones might look a bit small on mobile, but I would prefer it.
Great work and site bookmarked.
Thanks for the feedback! You are playing version 3 right now. Version 4 will be a massive bugfix – I am intending to release it by this Christmas.
"Seeding/sharable link" idea is bound to daily game feature – and this is a next feature pack going out in Q1 next year.
Card switch is also in the roadmap, it is part of the non-existent (for now) settings system.
Appreciate for the kind words! Stay tuned!
Looking forward to it!
I think ur freecell game is broken, is it ?
It may be, I am working on bugfixing the whole platform right now (to be released by EOY). What is not working for you?
I am working for a while on a command line game about spacepirates playing basketball across the galaxy. The game is a basketball managerial game with some pirate-y stuff. It's a P2P game with no central server, built on top of libp2p.
It runs as a terminal application, meaning that you just need to run it from your terminal, but you can try the game over ssh without installing: `ssh frittura.org -p 3788`

Building an app that scans file systems prior to being migrated into M365. Looks for common governance issues and file and folder trees that won’t play nice in SharePoint. Not a migration tool as such, just something to scratch a consultancy itch. Python and Tkinter for now until I hit something that requires more complexity. Also a command line version that I’ll use more often. This probably could have been a PowerShell script but this is more fun.
I built a universal live speech translating app.
I’ve been playing around with the Whisper models for a few years now. Last year I had an idea about how to run Whisper Large v3 in real time. That idea became ScribeAI.
Because the quality of transcripts was so high, much higher than I could get with Parakeet, I started to think about how it would serve as a good input for live translation. I played around with this and was surprised by how good the results is, I’ve used it to follow along political speech’s from foreign leaders and other content I’d have just never been able to consume before. You can translate by bringing your own LLM service API key or using the inbuilt Apple Translate models (for a completely offline experience).

A side project for my side project: I built my own static site generator with React islands architecture and MDX support, using Bun. (Build your site from .mdx files, output only html+css, progressively hydrate the client with React only as needed).
I wrote about it here: https://pcmaffey.com/custom-ssg/
Forkable template: https://github.com/pcmaffey/bun-ssg
I'm curious if you've considered using Astro? It's my go-to for that use case, been using it for all my side project sites.
From my post:
> Staring at the errors in my CLI, I realized I did not want to use another framework. It's why I had already discarded the idea of switching to Astro. Twiddling around someone else's abstractions and incentives, frustrations fitting together the final 20% of a project... I've been down that road too many times before. It's never fun. The tradeoffs _you don't know you're making_ are the biggest risk.
Fair enough. Had similar apprehensions after trying Next.js, but I've genuinely been pleased with the Astro experience.

I wrote a Telegram bot for video/image translation, and also Firefox/Chrome addons to help translate web content with smart content extraction and non-breaking layouts.
Check it out at: https://addons.subly.xyz & https://subly.xyz
The Firefox addon/Chrome extension is free, but you need your own OpenRouter/Gemini API key. The cost of web translation is really low, you can translate an article for ~$0.01 with really good quality. (You can try at https://addons.mozilla.org/en-US/firefox/addon/subly-xyz/)
I built it because I use Firefox the most and it seemed like no translate addon was good or simple enough. Chrome translate kinda works, but the quality is so low; it usually doesn't understand the article context.

Ooh very nice. Going to keep an eye on this, because while qlabs is nice, it certainly is up there in price for some features I require. Just had to spend nearly 100$ on renting it for this week!
Any plans on supporting video playback and rudimentary keystoning? The audio features in qlabs are alright, the video is its killer feature that similar software often touted as alternatives lack.
For the last 3 years, I have been working on a web tool to help me at work: debugging ASN1-encoded data (keys, certificates, Kerberos/CredSSP/SPNEGO/etc data structures, and more) and performing various cryptographic operations. This app is available online; you can try it [0] (no sign-in/up needed).
This December, I reached a huge milestone: I implemented ASN1 tree editing [1]. Now I can edit the ASN1 tree directly in the browser (read my blog post for more details: [2]).
I'm happy that I wrote this tool. I use it often to help me debug my protocol implementations and/or debugging. I know that some of my friends use the JWT debugger and ASN1 parser from this tool. Maybe some of you will find it helpful too.

Porting/reimplementing a Tcl interpreter from C to Zig, based on the design of Jimtcl. This is one of those sub-projects that started due to another project (folk.computer in this case). The biggest difference is thread-safe value sharing, and (soon to be) lexical variable capture.
But why? Right now folk.computer has about a 20% overhead of serializing and deserializing values as they get sent between threads, and it's also meant we can't sent large amounts of data around. I previously attempted to make the Jimtcl interpreter thread-safe, but it ended up being slower than the status quo. So, I started hacking on a new interpreter.
Commands evaluate, basic object operations are in place, but there's still a ton of work to do in order to implement core commands. It may even be good enough to swap in some day!

I'm working on adding features to the snakemake aws batch executor plugin. The existing plugin supports execution on AWS Batch by dynamically creating job definitions based on rule resource configuration, but was missing support for features like using different containers for different rules, consumable resources, secrets, etc. Two approaches:
1) https://github.com/radusuciu/snakemake-executor-plugin-aws-b... (my fork). Just add the features to the batch job building code 2) https://github.com/radusuciu/snakemake-executor-plugin-aws-b.... This is more experimental and not yet fully working. I wanted to try a few things. a) can we rely on existing job definitions (managed through IaC instead). b) can we implement a fire-and-forget model where the main snakemake process runs on Batch as well? c) Can we slim down the snakemake container by stripping off unnecessary features.

I’ve been building a crypto market visualization and simulation tool because I kept running into the same problem: TradingView is great for charts, but it’s hard to answer simple “what-if” questions like would rotating into another coin actually have helped or did trimming and buying back improve outcomes, or just feel good in hindsight. So I started building tools that simulate these scenarios directly on historical data. For example: - flipping from coin A into coin B and back again over a chosen period - selling part of a position and buying back later after a drawdown
I’m still early and adding ideas as I go, but it’s already helped me questions I had.
Examples: - Coin flip simulation: https://www.blockviz.xyz/simulation/coin-flip - Sell & buy-back simulation: https://www.blockviz.xyz/simulation/sell-buy-back
Curious if others here run into similar “this felt right, but did it actually help?” questions.
I'm working on a tool in golang to handle requesting access to private and sensitive databases in Postgres. The goal is to help orgs reduce handing out long-lived postgres creds with broad permissions.
The flow is you declare the databases and tables you want to access and the specific permissions you want, an operator reviews it, if accepted it generates a temporary postgres user with those permissions you need. Also, all the connections to the database are proxied through the app, so the domain name and port are random and short-lived, so you don't expose internal database hosts. As an extra, all SQL statements during the user sessions are logged if you want to see that.
It's available at https://github.com/yungwarlock/pam_postgres
My primary goal of this is to drill myself as a product engineer working on a technical product.
I just put something similar together but then on top of Openbao which generates temporary credentials/roles for Postgres. I created a website where people can request access and a specific group of people can approve the approve. After being approved, the database users can request temporary credentials in OpenBao for a specific number of hours.
Wow, this is same thing that this currently does, but aside from database creds are there any other kinds of credentials you've worked with?
I’m working on Lunara AI: https://lunaraai.app
It’s a meditation app where an LLM guides you without the usual back-and-forth chat. You set your preferences up front (style, duration, focus), then it delivers a structured session end-to-end.
I have a long list of ideas and features to try, but right now I’m focused on feedback. The app is live on the App Store, and I’d love input on: • What would make you try an AI-guided meditation app (or avoid it)? • What settings matter most to you (duration, tone, technique, background audio, etc.)? • What would make the guidance feel trustworthy and not “chatty” or generic?
If you’re willing to test it, I’m especially interested in first-session impressions and what you’d change to make it something you’d actually keep using.
This is the second app that I’ve tried with an AI voice for meditation. And frankly it’s off putting. The voice is great for other settings. But when my eyes are closed and I’m focused on nothing but the voice it stands out as negative.
Now I may tolerate that if you are significantly cheaper than the alternatives but that doesn’t seem to be the case.
I've been a long time Windows user (20+ years) who heavily uses WSL 2 as my dev environment with tmux / Neovim but I'm switching to native Linux before the end of this year.
I tried once 7 years ago but ran into major audio issues that were a deal breaker but I'm hoping the Linux kernel has improved. I have the same hardware as before.
My dotfiles have been public for many years and can 1 shot a new or existing system in a few minutes with a bunch of command line tools on Debian, Ubuntu, Arch (with or without WSL 2) and macOS. It has an install script and theme switching for a long time which I've used to set up a a few systems (personal desktop, laptop and work laptop).

Right now I am working on fixing my PC because it is randomly restarting out of the blue during a video call, or during some coding or when it is left unattended. Highly annoying. Right now I basically ruled out anything but the ram and mobo which would be very costly to fix because of Open AI shenanigans.
did you check the logfiles and stuff?
Of course. I.e. one minute is some error from tailscale and then new boot. Does not look like software issue. I am running boring Debian.
Working on a little project to make Spotify recommendations better.
You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.

I did (with the help of GPT) a simple script to deploy my Django+Celery projects to DigitalOcean. I was a bit afraid of that in the past, but now it's just a script that, after configuring a few variables (IP, etc), runs smoothly and gives me a perfectly deploy for a side project on a DO droplet. And also I can run again to just deploy a new version.
For most people this is silly but I am super happy that it works.
I am working (mostly vibecoded) a Git history explorer in Go+modernc.org/Tk9.0: https://github.com/thiagokokada/gitk-go. It is heavily inspired in gitk, this is why the name and usage of Tk for the interface.
The reason for it was because after testing multiple Git history explorers, I still think nothing beats the gitk. Sublime Merge is probably the only alternative that I would seriously consider but I don't really like the UI and the fact that it is proprietary (I am not against proprietary software but I prefer an opensource solution when available). Other alternatives have some bugs or the interface few too slow. gitk itself is mostly fine, but sadly it tries to load the whole repository in memory and this is causing issues every time I try to navigate through nixpkgs (I can see the memory consumption going through the roof while the UI slow down to a crawl).
gitk-go loads a batch of commits (1000 by default) and once you get at the end of the list it loads more. I also add a few features that I miss from gitk, for example if you do any change in the repository (change branches, add files to stash, etc) it will automatically reflect in the UI.
Again, the code is mostly vibecoded since this is the first time I decided to try this from scratch. The code works well for my use cases and it is enough to replace gitk for me, but I can't guarantee there is no bugs and the amount of tests are small. But still, it was fun to see something that I wanted to create for a while (I had this idea for a long time since the issues with gitk that I was having) finally taking form. Probably the program is not useful for anyone but me, but if anything this is a feature, not a bug.

It’s “Hotwire for command-line apps”, meaning you can ship a CLI in a Rails app without building an API. The dream is to make it work for all major web frameworks.
Terminalwire streams stdio, browser launch commands, and a few more things needs to ship a CLI for a SaaS quickly.
The best part is when you want to ship a feature for the CLI, you don’t have to worry about pushing out updates to clients and making sure it’s compatible with your API.
A more interesting development are companies that are using it as a replacement for MCP in AI stacks. They’re reporting less token usage and better overall results.

I'm working on a beginner-friendly online programming language for teenagers who want to learn to code. I think there is not a clear enough winner for what teenagers should do after they learn Scratch so I am trying to make it.
I saw this shared recently. The site presents nicely, and I agree there's a gap there. As a university professor, the story of my students' learning has pretty much been; Scratch, some Python, and then they pick up whatever early-college curriculum is. There's a strong preference for scripting languages like Python and JavaScript.
When you say "what teenagers should do after learning Scratch," what do you mean exactly? Should do to what end? How would Easel present as "the clear thing" they should do? I suppose Scratch wasn't really chosen by these young people; it is obviously simple, and has the prestige of MIT. Schools followed suit.
You're in a different situation, where you have to meet this market in the open. When I visit your site, I am met with code. It's not apparently simple, and a beginner wouldn't be able to distinguish it from any other games programming framework. I think it's actually scarier-seeming to a beginner than something like Godot's scene editor, where you can just drag images from your disk into a prototype-view of your game-scene.
I hope my plainness in stating this isn't taken as an insult. You've got so much work there, and the site is impressive. I also care about this topic, age-range and the learning process, so I'm trying to be helpful with my perspective.
Thank you and I am pleased whenever someone engages and gives me their honest thoughts, it is always helpful.
Maybe I'll rewind a bit, and I'm sorry if this is a long post!
I've just had a teenager who finished making a Chess game in Easel after about a month's work, his most advanced programming project so far. This teenager started in Scratch, has done some Python, but the language they have spent the most time in has been Easel. I've also had a couple of teenagers who have said things like "I suck at coding" and yet make spend months making these quite sophisticated Easel projects full of coding. These two teenagers also did a bit of Scratch but also were lost and disengaged when it came to Python. This mirrors what I've seen in Code Clubs as well, where teenagers just lost interest when shown Python.
Eventually, if someone is going to learn to code for real, they must make the transition from a visual programming language to a text-based programming language, and I know that I have seen teenagers get lost attempting to cross that gap. There are teenagers who obviously have had no trouble with this and that's great, they should go straight to Python or JavaScript or whatever is their heart's desire!
The difference between Scratch and most other programming languages is more than just visual vs text-based. Scratch is actually this cool concurrent, asynchronous, event-driven programming language. This makes it easy to write things like "wait 0.3 seconds" then "move 2 steps to the right". Most other game engines, including PyGame and Godot, instead use a frame-by-frame model. This means you often have to code things as state machines, where you pick up and put down state so that an entity can remember what it was doing next frame. That example of "wait 0.3 seconds" then "move 2 steps to the right" would require the control flow to jump up and down the codebase between state and logic, which means the shape of the code no longer mirrors the step-by-step of what it is actually doing. I think Scratch is successful not just because of its visual coding, but because its programming model allows for step-by-step logic to look like step-by-step code. There's no reason a text-based programming language couldn't also have this property.
Easel is concurrent, asynchronous, event-driven, like Scratch, which is why both Easel and Scratch code can be written in this sequential step-by-step way that you can't easily achieve in other programming languages.
Why can't you just write `await sleep(0.3s)` in other programming languages? Their issue is you can't cancel an `await`, which means it is easy for an asynchronous task to outlive its entity and so they are not safe beginner-level constructs. Scratch solves this implicitly because all scripts are part of a sprite, and when your sprite is removed, all its concurrent scripts stop. It's so intuitive that it doesn't really need to be taught. Easel has a similar thing but in text-based form - it is a hierarchical programming language and everything inside of an entity's block`{ }` gets auto-cleaned up when it dies, including all asynchronous tasks belonging to that entity. I think that's why in Easel, I've seen teenagers spinning up hundreds of asynchronous threads all the time without any problems.
All of this is to say that Easel is like halfway between Scratch and Python. It keeps a lot of the intuitive parts of Scratch's cool programming model, but in text form. My hope (and we have seen this already a few times) is that it can help more teenagers cross the gap from visual coding to "grown up" text-based programming languages.
The reason the code sample is at the top is actually because I saw a teenager talk aloud as they were reading that code and understanding it in real-time. It was super cool because that's it, that's what I've been trying to do - make a text-based programming language that is legible to beginners and not convoluted. And I'm trying to figure out whether it is possible to replicate that moment over and over again with new teenagers.
There is a lot more to it. Easel adds a lot of other stuff like a physics engine and automatic multiplayer. But this post is getting long so I will stop there. I really appreciate the thoughts. I am definitely going to be thinking about how that homepage is presenting itself and I think it is fair what you say that it doesn't look simple, and doesn't look different to any other game engine. That is very good feedback!
Interesting. I admit I have to put my prejudice away to accept that in this case a programming model focused on events is probably good for the reasons you're stating, since those sorts of instructions you want to support, because those kids got their start on Scratch. Well you're definitely doing the right work in just making appealing games with it. Learners want to feel like whatever they want is possible, even if the "whatever" isn't yet well-formed. Your bee-line game is a really fun toy.

I'm working on brand new type of collaborative whiteboard that allows anyone (or team) to drag-n-drop items from their devices onto the board.
The problem I'm solving: On a team, people and their files are scattered everywhere.
Solution: A canvas that attempts to open (and edit) as many file types as possible (images, xlsx, pdf, docx, cad). This means you can have people and files on the same page.
It's the only whiteboard that can natively render docx and pdf so far; these can also be edited directly on the board without having to use dedicated software.
It has a built-in Drive where you can store/backup files that syncs across your devices.
There's a few widgets such as Kanban, sticky notes, cards.
And of course, there's agentic LLM (Gemini 3 Pro) that can take actions such as viewing the board, reading documents on the board, and editing items on the board. For example, you can tell it to read a pdf, then write a spec sheet (in docx), or create tickets on a kanban.
I'm launching a private beta next month if anyone is interested in testing it out and giving feedback.

It's a way of working/tools for working with an LLM that allow you to track decision tree graphs, have the robot make more informed decisions and build its own logical chain for history keeping, and modeling all the work as a DAG of events, goals, outcomes, decisions, and observations that network together to allow you to work better/smarter/faster, giving it a living and recorded memory and ways to explore all this.
It's easiest to check out the short demo on the site.
It also links to the live graph of how the tool has built itself.
http://notactuallytreyanastasio.github.io/deciduous/
Really interesting to see, because about 2 months ago I had a very similar idea, just with a bit more opinionated shape of the graph and context building, but more focused on the research and decision-making part. I started the development, but my focus eventually landed on a completely different aspect of that system.
So I have to ask, how well do you see it performing so far with regard to actually sticking to the data present in the system? Do you find the AI agents to adhere properly to the existing data?
On a similar note, can the "consensus" of the system be adjusted in a way where we keep the knowledge which was true at time T (decision provenance), but we avoid having that bit of information affect current decision making?
It's doing a great job. It has built itself with itself, the story is here
http://notactuallytreyanastasio.github.io/deciduous/story.ht...
the time-relevant stuff is all well beyond anything it does. It keeps confidence weights and decision paths and can analyze those.
I've also been using it at work with pretty great success.
Cool name, with both hints at "decid[e]" and the graphs.
I'd be interested in integrating this with bug systems of decisions / goals, with actions being comments on those bugs (for work purposes) instead of having a custom deciduous-only DB.

2. Sometimes a good post is ignored due to a bad title, sometimes I still have no idea what the post's theme even after I read a few paragraphs.
3. I want to filter out some posts I'm not interested in, but I realized I need read some other posts it's not a simple yes/no problem, so I gave every post a interesting score based on my own preference
so I built this tool to save my time while not missing out too much on hn

Working on improving the data pipeline for https://iplocate.io - an IP intelligence service I've worked on since 2017. A couple of recent focuses:
1. VPN and proxy detection. We already track dozens of providers, but we can do better here. There's also a bunch of metadata we collect as part of this process which we don't currently surface, so I'm looking at what else we can bring to our databases and free API.
2. Better detail and evidence on how we build and test our own geolocation database, which we create from scratch. There's been a recent trend of misinformation about geo accuracy, including from some other providers, so I want to better explain the accuracy (and inaccuracy) of various techniques, our policy for when we prefer certain data, and so on.
(Open to partnerships for any folks looking for a new provider!)
Fringe physics: Trying to understand WTF the A field is in electrodynamics, and how I can measure it for a price I can afford. Specifically, I want to communicate through a wall of rock or sea water at VHF frequencies, with high bandwidth. I just upgraded my subscription with ChatGPT to try to grok all of the physics involved. It decided that since this could be used to covertly exfiltrate data, it wasn't something that could be discussed. ;(
Recently a friend acquired a Collins KW-1 transmitter, serial number 1. I helped him get it working again after a long period of disuse by it's previous owner. You wouldn't believe how often it turns out that wires and bolts don't actually conduct electricity.
Maybe I can help with one or two conceptual things. In classic E&M a field describes the potential (or force, if you prefer) a test charge would experience at that point. Note that the general case is impossible to visualize, as you're associating 6 numbers (3 for E 3 for B) with every point in space, so we normally think of simple setups and slice them up. Accelerated charges make waves in the field which are WAY more complex than people think. The way you model matter is dependent on the frequency of light. For visible light you normally think of it (especially metal) as a crystalline lattice of some characteristic length, electrons that can jump discrete energy levels, with molecules forming some sort of dipole that has more degrees-of-freedom (wobbling, twisting). I don't know about VHF, but the wavelengths are huge, like kms, and therefore way too low energy to cause electron shell jumps, so you'll probably model matter according to some very general characteristic like permittivity and conductivity. For seawater (which is a good conductor) subs use ELF, which is 100s of kms in air and can only communicate at bits/s. It's a fascinating topic, and very niche. Good luck!
Electrodynamics is taught to literally millions of people in Physics or engineering degrees across the world. It is the furtherest from fringe as it could be.
I would recommend following along the MIT OCW course or similar, doing the exercises. Use AI to help you follow the course and ask questions about things not clear to you.
- Building a micro-learning platform that uses AI-powered role plays and conversational assessments to gauge learner understanding instead of eg. a multiple choice questionnaire.
- I’ve just started designs and initial setup for a personal productivity system heavily inspired by the Newton & HyperCard and built in Rust. Idea is to use LLMs to build GraphRAG-like connections between content & break out of the standard app+document model. My current thinking is having ‘frames’ of content (notes, sketches, events etc) that are acted on by capabilities and displayed in views (timeline, calendar, stack, knowledge graph etc).
- Also working on a static site generator and CMS webapp that creates sites that can be viewed on anything, from web browser to TUI. Like if Gemini or Gopher also rendered to html.

I resurrected some of my old code for computing hash collisions: https://github.com/DavidBuchanan314/birthday_party (it's actually more of a rewrite)
It can collide 96-bit truncated sha256 in under 24 hours on a 6700XT.
Next steps are a) figure out something interesting/useful to do with it (beyond surprising people), and b) modify it to support accepting contributions from untrusted clients (see "Future Ideas" in README). For a sufficiently interesting answer to a) I could create a "SETI@home"-like system.
A ~102-bit collision would cost $$ worth of rented GPU capacity, and 128-bit is optimistically possible with enough crowd-sourced compute (a ~5-figure dollar cost if you were renting).

I'm still tweaking my tool for creating accessible Tailwind-style color palettes for web/UI design that pass WCAG 2 contrast requirements:
https://www.inclusivecolors.com/
There's 100s of color palette generation tools, where most only let you customize a single color then try to autogenerate tints/shades without much thought about accessibility or tints/shades customization. The main features of this tool are:
- Emphasis on accessibility. A live UI mockup using your palette warns you if your tints/shades are lacking contrast when used in practice for headings, paragraphs, borders, and buttons, and teaches you the WCAG rules. Fixing contrast issues and exploring accessible color options is also made much easier using an HSLuv color picker, where only the lightness slider alters the contrast checks, and not the hue/saturation sliders (most tools use HSL, where hue/saturation changes counterintuitively alter contrast checks which makes accessibility really tough!).
- You can tweak the hue/saturation/lightness of every tint/shade. This is useful because autogenerated colors are never quite right, and customization is really important for branding work when you have to include specific tints/shades. The curve-based hue/saturation/lightness editing UI also makes this a really quick process.
- Instead of just a handful of colors, this tool lets you create a full palette. For example, if your primary color is blue, you always end up needing other colors like green for success, red for danger, and gray for text, then 11 tints/shades for all of these, so you want a tool that lets you tweak, check, compare and manage them all at once.
It's mostly a demo on mobile so check it on desktop. I'm still working on making it easier to use as it probably requires some design background to understand, but really open to feedback!
I shared this last month, and it seemed to resonate with people, so I'll share again and maybe new eyeballs will see it this time. I'm continuing to build a body of work on my retro productivity software blog, Stone Tools.
https://stonetools.ghost.io
Previous articles which resonated with HN were on Deluxe Paint and VisiCalc. The latest post, "HyperCard on the Macintosh," seems to be making the HN rounds currently. Bret Victor himself chimed in on the HyperCard article over on Mastodon, filling in some nice historical footnotes. https://posts.dynamic.land/@bret/115716576717006637
Unlike many (most?) other retrocomputing explorations, I specifically do not look at games nor do I tie myself to any particular machine, though I'm focused on the 1977 - 1995 period. I spend a minimum of two weeks with each productivity title, trying to learn it, building things with it, and generally trying to understand its approach to solving problems. I'd characterize my writing tone as casual, conversational, and decidedly light-hearted.
Each piece of software (so far, knock on wood) gets me thinking about some other aspect of related computing history, so I explore that as a tangent. With the Superbase article, I talked about "the paperless office." With the VisiCalc article I considered its impact on less obvious industries, notably hog farming.
I hope the passion and effort I put into the articles comes through. If you're interested in computing history beyond just the games I think you'll find something of interest on my blog. "This Week in Retro" did a segment about me and my various projects as well, if you're curious to get an overview of what I'm all about (link is queued up at the start of the segment) https://youtu.be/UHYscl1Ayqg?si=7JM1sZagjoqvPjk2&t=2137
It started out as a take-home assignment for a job I’m interviewing for (they asked for about 10% of what I ended up implementing but I wanted to do/show more :). It’s an aggregator for crypto exchange data.
The app reads the public data stream from exchanges, handles the nitty, gritty details of each exchange’s websocket connections, deals with its quirks, cleans up and normalizes the data into a uniform structure (currently only supporting spot trades) then exposes it downstream as an SSE stream.

TTRPG Narrative Engine — https://test.qualy.dev
I'm building a session prep tool for tabletop RPG game masters. The idea is to make a narrative engine rather than another static wiki. Most existing tools are great for storing lore, but they don't help you run the story. I wanted something that supports the "create now, refine later" workflow — get ideas into structure fast, then refine as you play.
Core features: - interconnected world-building (NPCs, factions, locations) and story-building (situations, fronts, clocks) - Bidirectional linking — connecting a story hook to an NPC makes that hook visible from the NPC's view - Clock system with milestone consequences that can spawn or edit entities - Situations fire different consequences based on outcome (players engaged vs. ignored the hook) - Material waste detection — flags under-connected content so you know what's prepped but unused.
The main workflow is mindmap-based. Each entity gets its own context layer showing direct relationships. (Soon available in demo version) Working on next: automatic player-facing content. As players complete situations, public notes from involved entities get published — so the GM doesn't have to maintain a separate campaign log.
Stack: TypeScript, Effect-TS, SolidJS, Cytoscape (graphs), Leaflet (maps)
The hosted version is rough — I've been using it to get early feedback from GM friends. Happy to hear thoughts from anyone who preps campaigns

I've been working on Mukbang 3D for the past year and a half—an iOS app that converts food videos into interactive 3D models using photogrammetry. Record a short video of food, and viewers can rotate/zoom/explore it while the video plays.
I recently added pose tracking of the 3d model so I can overlay 3d effects onto the underlying video.
Here's a demo: https://mukba.ng/p?id=29265051-b9c7-400b-b15a-139ca5dfaf7e
Continuing work on my AI game development agent for Godot, Ziva[0]. Basically, big games are made in game engines, and game engines are hard.
Right now you can use it to chat about and modify basic things in your game; it automatically adds open scripts, scenes, and assets to your context, and uses around 50 MCP tools for editing. Currently working on refactoring the agent loop to use Claude Agent SDK so we can piggyback off the Claude Code developer experience and focus purely on the tool and integration side.

I'm looking at how to introduce unique, borrowed and GC'd reference types into the IR for my VM/runtime.
I'm inspired by the language Lobster's compiler that specialises functions to arguments of either reference type as a way of doing something analogous to using "escape analysis" to allow objects to be owned by the stack. I think that perhaps specialised functions could be re-merged, with compile-time checks replaced with very cheap runtime checks taking advantage of "upper byte ignore" bits in pointers.
The VM will also need to support not just managed source languages, but also languages where unique and borrowed references are statically checked and possibly stored in objects.
Have been working on three micro-saas, all built in Elixir/Phoenix:
https://feedbun.com - a browser extension that decodes food labels and recipes on any website for healthy eating, with science-backed research summaries and recommendations.
https://rizz.farm - a lead gen tool for Reddit that focuses on helping instead of selling, to build long-lasting organic traffic.
https://persumi.com - a blogging platform that turns articles into audio, and to showcase your different interests or "personas".
Working on 2 SaaS: - https://socialbu.com (social media scheduling/management) - https://justblogged.com - blogging platform - in case you need a blog ;)
rizz.farm looks interesting. reminds me a bit of origami agents. will give this a try, ironically for the app i built http://rizzi.fun
Working on https://greatreads.dev/ A place to aggregate and find articles from developers' blogs. Right now, I'm building a submission form for people to submit new sources.
There is also a way to search for articles using vectors, it's called "Semantic Search". So basically you can ask, for example, "Postgresql and how to best optimize it." and it would search for articles touching that subject, or at least related to it.
Wondering about the best way I can add a weekly newsletter built on top of the content currently being ingested, and still looking for more sources to add to the database (let me know if you have any good recommendations).
This is very cool! I built something a little similar https://blognerd.app. I'm really interested in the RSS remixing idea, though I didn't quite crack it. I'll be interested to see how you get on
I’m building a web application to catalog your guitars and amps and pedals and record each time you service them and when you bought or sold them. It’s a free service and I’m looking for BETA users to try it out. I switched up the tech stack and went with Rails with minimal AI assistance to go back to feeling like I did back in uni when I was building applications for fun and had to figure things out by trial and error. It’s been nice switching gears and doing things my way.

I'm learning Java and hoping to finish a course and a big project I've been working on for a while.
I've started fund raising efforts for a project related to accelerating adoption of authenticated encryption between mail servers (it's time to move past opportunistic TLS).
I also launched a web browser extension last week, Blog Quest, which has some great early adoption numbers that exceeded my expectations. When I can find some spare time I'll start fixing up some of the early feedback/feature requests.

I'm building an application that can communicate with my Plex server, and also communicate with APIs like MusicBrainz and Spotify. From there I want to be able to track my Plex music rating history, and export playlists on Plex to Spotify for easier sharing with others.
There don't seem to be many automated tools out there that fit my need for this, so building out my own solution I have complete control over makes sense. It's a lot of fun to build this out exactly as I want to, rather than trying to configure a bunch of tools that I'm not familiar with and that don't meet my needs exactly.
The tooling I'm building up around this should hopefully make it easier for myself to get my playlists and track ratings off of Plex if I ever decide to abandon it for music listening.
I’m working on 2zuz, a product search engine that optimizes for the users rather than the advertizers.
The goal is simple: if you search for something specific, you shouldn’t have to scroll through ads, “inspired by your search”, or completely-irrelevant junk. You should just only see products that actually match exactly what you’re looking for.
Right now it searches across a few large stores and I’m iterating on the ranking and filtering. If you buy a lot of stuff online, I’d love feedback on where the results feel clearly better, and where they still fail compared to Amazon/etc.

I'm a product designer with no training in development. I've been hacking together a ridership data analysis platform for public transit planners using Claude Code.

I’ve been knocking around and getting various false starts on three ideas for a while…
- a videogame. I've got a pretty killer idea in an open niche, but the indie market is so massively oversaturated that it feels impossible to get eyeballs.
- a next-generation post-RSS newsreader. But news is so depressing these days. I think most of the world wants to ostrich and I don't blame them.
- a reboot of Svpply, my own shuttered startup. I'd love to just make (another) thing that's about excellent clothes and shoes and artisanal pocketknives, but the way the economy is going, this feels grotesque. I was lucky to make it the first time when luxury goods were attainable _and_ normal people could pay for necessities; that window has closed.

There are too many LLM-related projects. Setting up multiple runtimes, Python, Node, Go, Rust and then some environments, different CUDA versions, dependencies is tedious. Managing updates later is even worse.
So, I'm building a toolkit that allows to keep things simple for the end user. Run Ollama and Open WebUI configured to work together: `harbor up ollama webui`. Don't like Ollama? Then `harbor up llamacpp webui`. There are 17 backends, 14 frontends and 50+ different satellite projects, config profiles that can be imported from a URL, tunnels, and a helper desktop app.

I’m working on Paperboy (https://www.paper-boy.app/) a self-hostable service that generates a personalized daily research digest from recent arXiv papers (and optionally a few other sources).
It fetches new papers, scores them against a “research profile,” then produces concise summaries plus a short “why this matters” style rationale, and outputs an email/newsletter-like HTML digest. There’s also a small API for generating a digest, checking status, and previewing the render.
I built it because keyword alerts and generic newsletters were either too noisy or missed the stuff that was actually relevant to what I’m working on right now.
I'm working on https://www.numeromoney.com/pricing I don't even have the home page put together yet so marketing is still on the starting blocks! It's web app for helping to understand how you spend your money. I'm keeping it as simple as possible while trying to surface clear information about a persons spending. It came out of personal need (young families are expensive, it turns out!), and the existing products out there - YNAB etc were just too focused on budgeting. I just wanted to know where my money goes so I can focus on where I'm not spending it well.
I'm in the progress of open-sourcing (and extending) my static-site generator "CMS" (with big air-quotes).
The idea is to add dynamic content, i.e. reservation tool, to what is essentially a statically hosted web page.
Demo: https://astro-booking.pages.dev/booking/
A bit more details: https://www.nordstroem.ch/posts/2025-01-15-to-the-stars.html
My website is statically generated. The biggest problem I faced was adding comments to my blog, that didn't involve loading a ton of JS or third-party services, or add and maintain backend software (say php).
Do you think your dynamic content could be comments?
The live site has a blogging feature: Title, Text, Picture. Once I'll get to it, it'll be added to the demo site.
Comments is just the text aspect. So it's already working!
The question here though: in a low-trust environment, i.e. the public internet, what do you do with API key for your GitHub Actions/CI pipeline. Can they be narrow enough to be considered public? Can you get rid of the Cloudflare Workers?
I'm polishing up the second edition of "Hidden Markov Models and Dynamical Systems." The book explains several state space models and connects them to ideas about chaos. Here's a link to a pdf draft: https://www.fraserphysics.com/book.pdf and here's a link to source for the book: https://gitlab.com/fraserphysics/hmmds Once you install the source software, you can build a pdf for the book by typing "make book". I think that makes it reproducible research.

It's an AI-native email client. Launching soon!
My goal is to help people get done with email faster, so that they can get back to doing other stuff. A lot of the features are designed around this goal: unified inbox, AI summarization, AI email drafting, etc.
Some of these are table stakes but I think there's also an opportunity to significantly revamp how email is done in the AI age. Imagine having your own personal assistant that goes through your email and surfaces the highest priority things that you need to know automatically.
I'm again toying around with the idea of building an ActivityPub Server built around the principles of RDF, JSON-LD and the Linked Data Platform. [0]
It can work already as a "Generic" ActivityPub server and it can be made to work with Client-to-Server API, but given that there are not mature clients for that, I am now in the middle of an exercise where I am taking the existing server and implementing Lemmy's and Mastodon's APIs based on top of it. Once I can get any Lemmy and a Mastodon client working, I will then start changing their own SDKs, and then I can replace calls from their application-specific APIs with direct calls to Linked Data server.
Started a newsletter [1] focused on agentic coding updates, nothing else. Other newsletters/blogs cover a lot of generic AI news, industry gossip, and marketing fluff. Having a focused feed is something I wanted for myself and finally I have enough time that I can write this newsletter regularly.

A tool to build labeled object detection training datasets from large-scale satellite/aerial imagery collections: https://github.com/noahgolmant/label-tiles
Web maps usually join together lots of small images called tiles (this is why you see square patches as google earth/map loads). They do this by querying a "tile server" API. It turns out this standard can also be leveraged to label and fine-tune models on map imagery. In my day job we built infra to efficiently serve imagery through tile servers for map visualization. So I wanted to test out ML applications of that infra.
Buckaroo - the data table viewer for jupyter.
I recently integrated Lazy Polars and running analytics in background processes so I can reliably provide a fast table viewing experience on dataframes that would normally exhaust memory of the jupyter kernel. Analytics are run column by column and results are written to cache, if a column fits into memory individually, summary stats for the entire dataframe can be computed.
Here's a demo video of scrolling through 19M rows, and running background summary stats.

The simplest web framework and site generator yet – no leaky abstractions between you and the high-performance engine that is a modern browser.
As we pile more and more abstractions on top with AI, I have been on a really fulfilling quest fueled by curiosity to go more low level.
I've been doing a lot of assembly, C, WASM and plan to top it off with a look at GPU instructions and PTX. I haven't learned as much as in the last two months in years, it's been great. And surprisingly everything has turned out to be much simpler and easier to implement than expected once demystified.
Now to be fair, AI has sometimes given me pointers when I didn't fully understand something. Using Gemini 3 for free has been nice in that regard. However I consciously try to only implement code myself and to actually make sure I learned something that sticks.

Personal feed curation for events+more.
It feels like somewhere in the last decade we've all lost control over our email inboxes. While it would certainly be possible to filter and sort it, I've been wondering if it makes sense to just start with a system that is designed to intake a bunch of streams of information. Then it could be pointed at the raw information e.g event calendars and news-letters as well as streams like Facebook groups/Instagram where I don't want to actually go to those apps.
Speaking at a meta-level, this seems like what we should really be using LLMs for right now: use-cases where user controls what is done on their behalf.

I’m still exploring new forms of AI-powered learning tools.
The latest thing I’ve been working on is an adaptive mode inspired by the LECTOR paper [1]. Where each lesson is a single learning concept with a mastery score tight to it based on your understanding of the said concept, so in principle the system can reintroduce concepts you didn’t fully grasp later on, ideally making separate flashcards unnecessary.
It can be self-hosted if any one want's to give it a try!
[1] https://arxiv.org/abs/2508.03275
This seems really nice, and looks like something I have been wanting to exist for some time. I will definitely play with it when I have some time.
I know this is a personal project and you maybe didn't want to make it public, but I think the README.md would be better suited with a section about the actual product. I clicked on it wanting to learn more, but with no time to test it for now.
Thanks for the feedback, I did update the README and included all the futures and also there is https://talimio.com, I think it shows the future in a better way visually
Didn't see the website at first. Thank you!
I'm building a TypeScript to native code compiler, via the Dotnet CLR toolchain and Native AOT. This lets you use the excellent Dotnet std library - which in addition to being faster is also much safer than the npm ecosystem. There's also a node compat library, which exposes Node APIs but with CLR underneath.
The end result will be a binary (linux and mac for now) which you can run without NodeJS. Simple programs already work, and I have web apps very nearly running.

I’m working on Vocabuo (https://vocabuo.com/), a vocabulary-focused language learning app.
Two main differences between this and other Anki-like apps: 1) The words you learn are from YT videos, websites and ebooks you import in the app. 2) The flashcards are optimized specifically for learning vocabulary - cards automatically get audio, images, multiple sentence examples, words definitions etc. It can also create fully monolingual flashcards with just definitions or the words in dialogs.
My biggest flex is that I have users who have done more swipes than me (over 100,000).
Building the most effective typing application
https://typequicker.com
This is something that started as a passion project - I wanted to see just how effective of a typing application I could make to help people improve typing speed quickly.
It’s very data driven and personalized. We analyze a lot of key weak points about a user’s typing and generate natural text (using LLMs) that target multiple key weak points at once.
Additionally we have a lot of typing modes.
- Code typing practice; we support 20+ programming languages - daily typing test - target practice; click on on any stat in the results and we generate natural text that uses a lot of that (bigrams, trigrams, words, fingers, etc).
I’ve tried it and really enjoyed how it works. I’d like to suggest a small UX improvement: for a typing app, it would be much easier to avoid using the mouse. When a practice ends, the user should be able to press the RETURN key to move to the next practice. (instead of clicking the Continue button)
I'm working on my writing, of course. In the latest episode of my life, my mother surprised me with fresh news about the origin of my name: https://rikverse2020.rikweb.org.uk/poem/names
I'm working on a graph representation of complex data flows through a large organisation. The graph looks like crap, partially because hierarchical dagee graph layout algorithms apply a naive way of removing cycles that ruins the shape of the graph.
I've figured out a better way to remove cycles that preserves the shape of the graph in a way that works well for our purpose. Now I just need to figure out how to minimise edge crossings and line up nodes in such a way that it's more immediately obvious how the data flows between different systems.
I'm working on something called Kopi: a CLI tool that replaces the slow process of restoring massive production database backups on a dev machine with a "surgical slicing" approach, spinning up lightweight, referentially intact Docker containers in seconds: It spins up the exact schema of your source db and generates safe, synthetic datasets in seconds. It can, if you want, also replicate the actual data in the source DB but with automatically anonymized PII data.
It can replicate a DB in as little as 9 seconds.
It's Open Core: Community Edition and Pro/Enterprise editions.

I'm working on hand-building mugs. Throwing clay around in a studio, etc.
But I'm also thinking about it as a product manager based on my tech experience. Looking at what people like in mugs, creating templates to exactly size the mugs to people's preferences, creating re-usable molds to put repeatable components together, and taking detailed notes on exactly what I am doing in-studio to create a repeatable, reliable process to create a product that will sell.
It is going poorly so far, but each iteration gets better, so hopefully I have everything down before I end up with 100+ unsellable mugs in my kitchen.
Sounds nice! I could see where that could be simultaneously rewarding and frustrating. Best of luck to you.

A kanji typing game. Vibe coded it in two evenings.
A portable, robust desk cloud chamber with a 10x10cm viewing plate. It's taking ages and having just one AIO cooler wasn't the smartest choice, but nothing else would've fit. It's a way harder project than I expected, at least if you want everything to be vibration-resistant for car transportation and for it to last years. I've learned a ton.
Can you share more, maybe some pictures?
On a dedicated language analysis model. For starters, it will detect a text language in microseconds. For comparison, a popular LLM takes 100 ms (10 tokens per second) on a full GPU to analyze one token; this new project processes a token in ~100 ns on only one CPU core!

Still WithAudio https://desktop.with.audio . It's getting some attention and has actually sold licences!
Someone asked for a free license in exchange of detailed private review and bug reports. They have reported more than 10 bugs so far. I'm working on some of them right now.
WithAudio is a one time payment text to speech reader app. It's one time payment because it has no server and no recurring cost! A nice side effect of this is it's 100% private.
The fastest knowledge base for software teams, Outcrop.
A lot of teams enjoy using Linear for product management but still have to use Notion and Confluence for knowledge management. I’ve built Outcrop from the ground up to be fast with much more reliable search and realtime collaboration.
Hundreds of teams from startups and major companies have signed up for early access and many have made early commitments to support the development of Outcrop.
If your team would be interested, I’d like to hear from you!

I'm working on a collection of mnemonic images for learning written Chinese. Each has a solarpunk-style image referencing both the character's meaning and pictographic etymology, with the character overlaid and color-coded to indicate the tonality in Mandarin.
While I'm talking about it, do the folks here have any suggestions where I should make it available? I want it to be a free educational resource for whoever might want it.
For a fun project; rejuvenating a 1978 Chess Engine https://github.com/billforsternz/zargon. It's the second time I've worked on the same engine. The first time I got it working nicely on modern machines, running four orders of magnitude faster than in in 1978. This time I hope to get it running much faster than that. I found a bug in the 1978 Z80 assembly the other day. A blog post "Fixing a 50 year old bug..." or similar suggests itself.

I have been slowly progressing on writing a Rust like language that compiles to JavaScript for a few years now. With the rise of AI and it becoming better recently with Opus 4.5, specially with Rust, I've been trying to have a speedrun version of it.

Slowly degoogling my life. Switched to FastMail a while ago, it works. Have written a simple shopping and todo list web app, and a minimal photo gallery. All very simple, mostly for one user only: Myself. Using these as excuses to learn about coding with LLMs. As I have retired a few years ago, I can afford the time, and work with no stress or deadlines. Also slowly improving my beer tracker system. All this as perl-based cgis under Apache, running on my home server/workstation.

Working on building an investment assistant backed by real time data. ChatGPT and Perplexity finance are amazing, but all of them are based on web search data only, which is a big limitation in finance since realtime data is important.
We have an agent that has access to almost every data point you can think of in the stock market (as much as we can get), which gets leveraged before answering.
And we also figured out ways to build amazing charts in between answer snippets, which looks very cool. Investors are usually very visual.
Last week I spun up a HN clone for digital nomad news.
Since I was researching DNS and global mobility, and wanted to share links with others, figured I'd just spin up a link site (though I'm still the only user).
One unique difference is I have a field for English Title, since I consume a lot of Korean & Japanese articles and want to share these, but don't want to have people translate the titles before they understand why they should read them.

Refresh Agent is an AI Agent for SEO and Marketing Analysis.
If you've ever tried to use Google Analytics (GA4) and Google Search Console (GSC) to figure out what's working with your marketing, and what to do next to grow, you have probably got frustrated at some point.
It acts as a Marketing Strategist. You can ask questions like "why is my SEO traffic down this week" and it will give you a clear answer based on your site's performance data, as well as a checklist to improve.

When someone dies, you don't get even one extra second to access the documents and information they meant to share it with you. Trying to fix this problem with Eternal Vault.
Link: https://eternalvault.app
Another thing thats in early alpha right now is CapKit, AI professional captions for short form videos
https://capkit.app
Could you go into some detail regarding your approach to security? Presumably, due to the sensitive nature of the documents users will upload, you have a number of safeguards in place?
I do yes, I have a dedicated page for the same: https://eternalvault.app/security/
But here's a TL;DR
- Files are end to end encrypted with a master key generated by you on your device during onboarding
- How do your family access the documents when only you have the key and it's E2EE? The idea is the key is splitted via Shamir Secret Sharing when you add a trusted contact, once the doomsday is triggered and they recieve the notification, only then they can use their "shares" to reconstruct the master key and open your vault and access the documents

Lite³: a binary format encoding JSON documents as a serialized B-tree, making it possible to construct iterators on them directly and query internal fields at indexed speeds.

Very interesting. How does it deal with "holes" left by deletions/edits, is there an equivalent of VACUUM?
When overwriting fixed-sized values like integers or floats, the old value can simply be overwritten. Holes are only left if the overriding values do not fit in the old location (strings, byte arrays).
To clean up unused space, you start an iterator at the root of the document and recursively write to a new buffer. This will clean up all the unused space. This operation can be delayed by the application for as long as they wish, until the size trade-off outweighs the cost of rebuilding.

Where are your tags made? In china?
Then the counterfeit factories already have your chips and will simply include them in their product if you ever become successful.
Nope, as we configure the tags. For now we support to industry standard chips from NXP, but this will expand in the future to other manufacturers as well.

Overly specific LLM research into KV cache eviction.
The vast majority of tokens in a sequence will be irrelevant to an attention mechanism outside of a very small window. Right now however we tend to either keep all cache values forever, or dump them all once they hit a certain age.
My theory is that you can train model to look at the key vectors and from that information alone work out how long to keep a the token in the cache for. Results so far look promising and it’s easy to add after the fact without retraining the core model itself.

It's really something I want for myself. Lightweight, as fast as humanly possible, extensible via plugins (in fact the entire app is mostly plugins, with a small core to glue it together), and a tiny bit of LLM (call it AI if you wish) integration to ask questions about the database or generate/review queries.
I recently discovered Tauri. What was the development experience like? Is the project open source? I'd like to take a look :D

Reimplementing something I originally did in python in rust. Both vibecoded - want to get a better sense of how they compare and whether there is upside to be had from rust typing and „if it compiles it’s probably ok“
Thus far - uses way more tokens and noticing reduced steerability. The linting & fix loop seems much smoother though.
Follow-up - token use seems to be a claude code flaw, not a language thing. Think it's picking up build artifacts and crates

I've been working on a no-code multiplayer game editor. The idea is to let anyone create multiplayer games in a few clicks without writing code—and share them instantly.
The platform handles all what's necessary (and annoying to setup) out of the box: multiplayer, controls, mobile/responsive/ inventories, save/load, leaderboards, quests, dialogue, etc... Users just select what they want and configure it with clicks.
Technically, the engine just reads a config file and renders it for players. I've built all the foundation blocks that interpret the config.
I'll soon be onboarding game designers to stress-test the editor/engine. Still polishing templates so people have a good starting point, but it's functional and I'd love feedback!

Creating Daino Qt - a collection of components that makes Qt apps feel and look native on both Desktops and mobiles (each with its own set of challenges).
Developing Qt apps with C++ and QML is a blast - the fast performance of C++ and ease of use of writing UI in QML. But there is so much left to be desired with the built-in Qt Quick components - mobile issues like non native text handling, non native swipe-able stack view and much more. I’m aiming to bridge that gap.
So sad for a Qt old timer. Back when it used to be native on 3 desktop platforms...
It's still native (in terms of performance and ability to customize the look and feel) and working pretty well, it's just that not enough effort was put into making the built-in components behave and look like those on the platforms it runs.

I'm working on Kanji Palace (https://kanjipalace.com).
It's an app to learn Japanese language with AI. It has visual mnemonic images, JLPT progress tracker, Kanji info graphic, etc.
Later, I will add AI-comic creation based on Kanji characters you've selected.
I know 4 languages. 3 of those I learnt because of my family. I learnt Russian because of work (+fun). I feel that it is always best to go the classic route and learn a language from a manual (currently learning mandarin from a manual) and that gamified experiences of learning languages have a very low learning/effort ratio.
You can use the classic route in my app. You can browse Kanji characters sequentially and memorize them.
I agree that over-gamified experiences are detrimental. That's why I try to build features that help people immerse themselves in the language.

It helps to comprehend research papers (and not only papers - any document on any language) faster.

I’ve been working on "Next Arc Research" — https://nextarcresearch.com - a wrapper around my curiosity to understand how AI, compute, and capital might change markets by 2030.
It’s not a trading tool or product. More like a weekly, machine-assisted research project. Each cycle I run analyses on 120+ public companies across semiconductors, cloud, biotech, energy, robotics, quantum and crypto. The framing is inspired by Emad Mostaque’s “The Last Economy” thesis — the idea that when intelligence becomes cheap, the physics of value creation start to look very different. I originally built it for myself and retail investors in my family but I figure it could have more general utility so prettied it up a bit.
The system uses large-model reasoning (GPT-5+ though I've also tested Sonnet, Gemini and Grok) combined with structured scoring across technology maturity, risk, competitive positioning, and alignment to AI-era dynamics. The output is static HTML dashboards, PDFs, and CSVs that track month-over-month shifts. I'm adding to it weekly.
Mostly I’m trying to answer questions like:
* Which companies are structurally positioned for outsized upside in The Last Economy?
* How should I deliver the research so that it would have been actionable to someone like me 30 years ago?

Legal-tech: Using AI to help attorneys bill flat-rate instead of hourly. It's data intensive, but possible if you go through their old time entries and tell them the flat-rate price of all of their hourly work. 93% of attorneys bill hourly, primarily b/c they don't have any sense of the cost of the upcoming work.

A tool for K8S operators that replaces brittle imperative reconciliation code with type-safe state machines generated from declarative YAML definitions. It also bundles error handling / logging / metrics / traces for state transitions.

I’m working on an open-source thing that lets you co-draw diagrams with an LLM inside draw.io/diagrams.net.
You can ask the model to rough out an AWS/GCP/Azure architecture, but the key part is the loop: you still have the normal editor, so you drag boxes, rename stuff, add your own bits, and then say things like “clean this up”, “split this service out”, “add a read replica here”. The AI edits the real draw.io XML, it’s not just generating a picture, so you and the model are basically sharing the same canvas.
It can also try to rebuild a diagram from a screenshot/PDF and then you keep iterating together in chat + manual edits.
Recently I added “bring your own API key” for a bunch of providers and support for uploading PDFs/text to turn existing docs into diagrams.
Repo (just crossed ~10.2k): https://github.com/DayuanJiang/next-ai-draw-io Demo: https://next-ai-drawio.jiang.jp/
If you live in drawio a lot, I’d be curious where this breaks down or feels more annoying than just doing it by hand.

Vive Coding an AI App that searches the net for different types of financial assets and uses the data found to Predict the Future of Financial Markets, i.e. price projections. Just for fun, though the results are very accurate :)
Is it open source?
It's not ready for prime-time yet, so not open-source at the moment. I've managed to have it search over 9 asset types, including Crypto, stocks (e.g. different categories), but it is slow going as I am using a free-teer AI. It's found some stuff on the net that is barely in the pre-sale phase, and it predicts 10,000% gain but don't know if it is an accurate prediction or a massive hallucination. Also, I know this has the potential to be a money maker, but I don't have neither the experience nor the financial resources to host this online or make this a viable money-maker at the moment, unfortunately :(
Have you tried handing it over some test money on a trading platform to see the results? What prediction algorithm is it using?
>>Have you tried handing it over some test money on a trading platform to see the results?
Not everybody has test money to play with. I'm in that group due to the crap economy left behind by previous politicians.
>> What prediction algorithm is it using?
As money is an issue, all I have at the moment is Google's AI Studio which is definitely not opensource, in my view. Though it is more forgiving than other vibe tools out there with their usage quotas. The market predictor has no capabilities to connect to any proprietary APIs as that requires money. That being said, it should be possible to modify the code so that it uses proprietary APIs should anyone want to do it. For now, I'm just adding stuff to it via VibeCoding that I think could be helpful. The main goal is to turn it into a research App that finds potential assets that will double to triple in the near feature or stocks that are prime for shorting, etc. I am also thinking of adding investment simulation capabilities but not quite sure how to go about at the moment. Turning some of its capabilities as a learning platform could be a good way to monetize the app. Not really a serious app at this moment, though, as I lack lots of tools to accomplish this.
Based on the code provided in services/geminiService.ts, here is the breakdown of the algorithms and sources used by the market prediction AI application:
Prediction Algorithm: The application does not use traditional quantitative statistical models (like ARIMA, LSTM, or Linear Regression) running on raw numerical data. Instead, it uses a Generative AI / Large Language Model (LLM) approach:
Model: The app utilizes Google's Gemini 2.5 Flash (gemini-2.5-flash).
Methodology: Context Gathering: The AI first performs a real-time Google Search (tools: [{ googleSearch: {} }]) to gather the latest text-based data, news, sentiment, and technical analysis summaries available on the web.
Semantic Analysis: The AI acts as a "Senior Financial Analyst" to interpret this unstructured data. It synthesizes a sentiment score (0-100) and predicts future price targets based on the qualitative data found (news catalysts, earnings, etc.).
Chart Generation: --The historical and forecast charts are generated mathematically within the code using Deterministic Linear Interpolation. --It connects the current price to the AI's predicted future price targets (1 week, 1 month, etc.).
--It adds algorithmic "noise" (randomness seeded by the asset name and date) to simulate market volatility visually, ensuring the chart looks realistic but stable for the specific day.
Data Sources: --The application relies entirely on Google Search Grounding. It does not connect to specific hardcoded financial APIs (like Bloomberg or Yahoo Finance API directly). Instead, it instructs the AI to search the public web for specific types of information.
Based on the prompts defined in the code, here are the sources and data points the app targets:
Real-Time Aggregators & Search Engine Results: --Live Google Search results for real-time price estimates. --Global financial news outlets (indexed by Google). --Market sentiment analysis from web summaries.
Regulatory & Official Documents: --SEC EDGAR Database: Specifically targeted in prompts for Stocks, Quantum, and Cannabis strategies to find filings.
Company Press Releases: --Used to identify fresh catalysts like contracts or product launches.
Technical Data: --Support and Resistance levels (retrieved from technical analysis articles found via search). --Relative Volume (RVOL) and Intraday Volatility data (for Day Trading strategy). --Chart patterns (Bull Flags, Pennants, Opening Range Breakouts).
Sector-Specific Sources: --Crypto Launchpads: Seedify, DAO Maker, Polkastarter (specifically for the "AI Presale" strategy).
Venture Capital Reports: --Data on VC investments and insider buying.
Industry News: Specific searches for Quantum Computing breakthroughs, Cannabis legalization news, and AI technology updates.
Market Dynamics: --Short interest data and borrow fees (for the "Short" strategy). --Analyst upgrades/downgrades and price targets. Macro-economic trend reports.
As I mentioned earlier, it actually found lots of legit assets with breakout potential but also finds crypto asset for that I suspect are scams but have a presence on the web.
Hope that provides a bit of context to your query.

My twins (in high school) and I are building an AI study buddy.The idea is simple. A peer-level “study friend” you can work alongside, ask questions, and stay on track with.
It’s not doing anything ChatGPT or Claude couldn’t do. The goal is packaging it into something that feels a high-schooler would actually want to use when they’re studying.
We are also using this as a weekly project to learn the abstract stuff. Product thinking, design, pricing, marketing, and how to turn a vague idea into something real. Each week the kids prioritize a feature, research it, write up the idea, and then we build (or cut) it together.
Our stack is Claude Code, TypeScript, React and it's hosted on Cloudflare Pages for frontend + Workers for API.
No login or credit card required to try this out. We welcome your feedback.

II’m currently working on Focusflows.eu, a tool I’m building to help people improve their focus while working or studying. At the same time, I’m exploring new ideas around productivity and digital well-being, and experimenting with features that make it easier to stay focused without feeling overwhelmed.
I've been working on a LLM fiction writing workflow and associated tools. It's built on agentic coding tools with lots of structure, guidance, prompting, and critique. Almost all of the flow is on the filesystem and using a custom command-line tool, making it accessible to agentic programming tools. (No MCP though; it seems superfluous?)
I was fairly neutral about the tool for a while, but lately I've been going all-in on Claude Code, using things like rules and subagents.
It's also built to "rerender" the story, for instance rewriting it (slightly) for voice, translate it, or target different reading levels or background. I'm interested in translating stories for language learners in addition to simply translating into other native languages.
I'm also hoping to create some stories that stretch the medium. Perhaps CYOA (though I'm struggling with understanding what a CYOA is good at), though also other multi-perspective stories with reader autonomy in how to read through the story. LLMs make it easier to overproduce content, so you can give the reader flexibility without feeling regret that much of the content will be skipped, or rewrite passages for readers who jump into stories part way through.
Producing quality content is hard, and frankly kind of expensive, which is why I'm focused on finished products instead of interactive experiences. Though I do look forward to some future opportunity to take these rich characters that are grounded in full stories and find other things to do with them.

I don't have a link to share just yet, but I'm working on an LLM coding agent that can modify its own context and is given hints on when and why that would be useful.
I expect it to make it possible to not think about when to reset back to a clean session. I also expect it to be more efficient as it will clear out all the "garbage context" that only serves to "confuse" the LLM, cost more tokens, make responses slower, etc.
Once I get a working prototype, then I will test the feature by using it while reimplementing it in other open source agents to get a feel for whether it has the effects I'm expecting.

I've been working on a game for playdate, part time for the last year+. It's a wonderful device and community. The hardware constraints are extremely freeing, and inspires creativity. Mostly Lua, but if you want to push the boundaries, you need to go fairly low level C, and I've found pushing in those boundaries to be just a blast. It's great platform if you're interested in a game dev hobby.

I'm working on WishKeeper https://wishkeeper.io.
It's a webapp that lets you create wish lists and share them with family and friends. The key feature is the claim system: when someone decides to buy you an item, they can claim it so others know it's taken, but you never see who claimed what or even that it was claimed at all. The surprise stays intact. You can also split big purchases. If someone wants a $400 stand mixer, multiple people can chip in allowing family tight on cash to feel like they're contributing without having family members feel like they have to put small items on their list just so everyone can contribute.
I kept it deliberately simple. No social features, no feeds, no ads. Just lists with items, links, prices, and notes. You create a list, share the link, and you're done. No group chat gymnastics required. It's free to use. I built this because I wanted it to exist, not because I had some grand monetization plan. You can sign up and create lists without a credit card.

I'm working on Ward, a Chrome extension that detects browser scams/phishing using lightweight LLM models. Our target persona is elders, young children, and anyone who's not as tech savvy. When explaining it to people, I call it a "modern antivirus", because it can detect anything from malicious scripts on a page to grey-area misinformation on social media.
I'm bootstrapping and covering LLM costs for Ward's first couple hundred users (got about 50 users at the moment) to improve it. We have a local mode for added privacy and are dipping our feet to gauge biz. interest (client-side phishing protection is unparalleled).
I've recommended it to friends, colleagues and loved ones. I dogfood my own product, and it even surprises me every day how much more mindful it makes me of my browsing of harmful content. Would love to get feedback and testers from HN.

Just released the next version of Isograph https://isograph.dev/blog/2025/12/14/isograph-0.5.0/
TLDR the incremental compiler rewrite is finally bearing fruit. Namely, because we no longer have a batch compiler (i.e. we don't bail on the first error), we can
- provide LSP results (hover, goto def, etc) on non-broken parts of your isograph literals, even in the presence of errors
- surface those errors in VSCode, and
- fix those errors with auto-fixes!! (https://www.youtube.com/watch?v=6tNWbVOjpQw&t=314s) Which is to say, select a field that doesn't exist, and let the compiler create the isograph literal declaring it.
It's a great feeling to see this level of DevEx

working on a new interface for llm chats, that allows you to branch the conversation to multiple streams
actually started as a new chat app but eventually I figured it could be used for LLMs
I'm building a yet another AI chat app.
My initial goal is to make a functional SillyTavern (AI roleplaying) replacement. SillyTavern builds prompts from a few rigid buckets (character, scenario, lore, system prompt, author's note...), which makes complex setups hard to manage. Content gets duplicated, settings have to be toggled in multiple places, and it’s easy to accidentally carry or modify state across conversations. Over time, it becomes difficult to tell what context is actually in effect.
I’m building an alternative that treats context as small, reusable pieces that can be composed and organized flexibly, rather than locked into fixed categories. Characters, settings, and behaviors can be mixed, reused, or temporarily enabled without duplication or manual cleanup, and edits preserve clear history instead of rewriting the past. The goal is to make managing complex context deliberate and controlled instead of fragile.
Although I’m trying to get the functionality required for roleplaying done first, the app is generic enough for other AI workflows where fine-grained, explicit context control is an improvement over existing chat interfaces. Think: start a new conversation with an assistant and start checking off rules, documents, and instructions to apply to the chat. Regenerate responses with clarifications or additional one-time context layers.

A desktop application to visualize and document how tasks flow through a dynamic heirarchy of AI agents.
https://omnispect.dev/
Is this API only, or can a person use subscriptions (like claude max)?
It uses your existing subscriptions and supports all the major CLI and API providers. There's no cloud features of Omnispect itself, it runs locally except for calls to the LLM providers.
Claude Opus 4.5 is used as a routing agent, which selects the most appropriate LLM provider and model tier to delegate a task to. For example, the routing agent might delegate a single large task to GPT-5, which in turn delegates multiple small tasks to Haiku agents in parallel, then Gemini reviews all the work.
Omnispect lets you view the delegation tree of prompts and responses that spawn from your initial prompt.

A few years ago, I made a model skinner for Tribes 2, a ~25 year old game that still has a loyal following: https://exogen.github.io/t2-model-skinner/ (if you check out the Gallery link there, you'll notice this app resulted in a whole new wave of skins, and even a Halloween skin contest)
To satisfy the urge of doing something else ambitious in the browser, I'm now doing the same thing for Tribes 2 maps: trying to make a web-based map viewer and editor: https://exogen.github.io/t2-mapper/ (editing/creation part still in progress)
I got this working for most maps pretty quickly. It translates the mission object tree from the Torque .mis files into a Three.js scene graph. Eventually though, I noticed that some mission definitions were more dynamic – Torque .mis files are really just TorqueScript .cs files with a different extension and some pragma/magic comments. So, to actually handle every map would require not just a mission file parser, but a whole TorqueScript runtime. Implementing THAT part seemed really tedious and, frankly, uninteresting to me. So I had Claude Code get a whole TorqueScript transpiler and runtime working. Now, when you load a mission, it actually runs all the same scripts that Tribes 2 runs to load the mission, all the way from server.cs and its `CreateServer()` function.
Currently, I'm continuing to get its rendering matching Tribes 2 as closely as possible, and setting things up so that live editing of missions will work.

Building postgres server as a library. Some early success, but initdb and in-process restarts are much harder than expected
Do you mind elaborating more about the use case? Postgres itself is heavily engineered around OS process boundaries for both correctness and resiliency.
I'm not sure it'll be a serious project, but the main goal is to use it in CI or dev, where setting up postgres is kind of a pain.
I got it to work already by setting up the global context in single-user mode (like postgres --single) and exposing bindings for SPI operations.
Yesterday night I got extensions working, but as this project builds as a static archive, the extensions also have to be part of the build. Both plpgsql and pgvector worked fine.
The bigger challenge is dealing with global state -- comparing the pre-start and post-shutdown state of the process memory, about 200 globals change state. Been slowly making progress to get restarts working

Hi HN — I’m Gerome, and I’m working on CodinIT.dev.
TL;DR: CodinIT.dev is a local-first, open-source AI full-stack app builder that turns natural-language prompts into prototype → production web apps. It supports local/self-hosted workflows, connects to databases (Supabase), includes an integrated terminal and git automation, and plugs into 19+ AI providers so you can iterate fast. Download desktop app at https://codinit.dev .
A few quick facts
What it does: Generate full-stack code from prompts, preview instantly, and deploy anywhere — built for indie hackers who want full control of there code without vendor lock ins (open source).
Where the code lives: active repo and org on GitHub — org name is codinit-dev.
How to try it: download and run locally; the dev flow runs with pnpm run dev and serves locally from your machine.
Progress & current priorities
Stabilising the live code execution sandbox and improving safety/UX for file uploads and agent orchestration.
Tightening integrations with community LLM providers and adding more framework templates.
Improving contributor docs and reducing onboarding friction so people can run it locally without hurdles.
If you want to poke around, try the app or the GitHub org and open issues/PRs. I’ll hang around to answer technical questions here.

Something small that has been on my mind for the past decade or so -- assistant chatbot.
Basically I long wanted to plug a chatbot into my messenger of choice with all sorts of tools for quick use, of course after the emergence of LLMs it was only a matter of time before I find time for it.
As an experiment I have decided to use Claude code + opencode to develop it, and after some trial and error I am very thoroughly impressed with the results, it grew to a nearly 10k LOC in a week and it is still very much manageable, I haven't changed a single line of code manually still.
I have developed it as a "core" that imports modules with a rigid and thoroughly documented in a spec.MD file interface, and every single bit of functionality essentially acts as a different sub-app that can consume events that trigger it and handle all of the internal logic within itself, that way everything is separated nicely and totally manageable within LLM context.
It does everything from setting up and sending reminders and todo lists, helping me track car mileage and fuel consumption, getting an overview of the day ahead(sometimes if task is important even a reminder few days prior to its date), to even opening my front gate. And all of that is exposed to 'core' chat module through tool calls, so I can request anything in plain English or voice.
Also has a web-ui where I can review tasks, reminders, settings or search past conversations.
Been using it a lot, and since I'm using groq for inference, I still haven't even needed to pay a thing, since it fits within the free limits

I mentioned this a few months ago, but have made progress since - I'm working on an alternative to subscriptions for online publications. Instead of subscribing to entire publications / blogs, publishers would register their publication on this network and configure thresholds and pricing. Add a bit of code to the site and a paywall will show up, allowing readers to pay for individual articles. The prices would be minimal, amounting to less than a dollar in most cases. i.e. reading articles using micro-transactions
I know it's been tried before, but I thought I'd attack it with a few different angles - web based, no chrome extension, thresholds to help verify the article is worth it, extensive use of an aggregator to help with discovery and validation.

I'm just getting started with YouTube content creation. I do reviews of vintage software. Here is Microsoft Frontpage: https://www.youtube.com/watch?v=O6DAh7uFEhU
I've been taking some time off from https://gethly.com, as majority of functionality I wanted to implement and offer to customers is done, so it's mostly just some tweaks here and there.
I was pondering doing something in regards to decentralised consummation of content. I am beginning to see how various websites are walling off their content and centralising everything whilst also monetising access to it for themselves and kicking content creators out, forcing them to run their own websites and use multiple backup platforms(mostly the dying youtube).
So I was thinking about flipping it on its head and instead of going to different websites to consume this content, like youtube, twitter and whatnot, people would have a single program to aggregate it instead. Then it occurred to me that this is what RSS/Atom was made for, kind of. So I am just letting the idea marinate for a bit and maybe next year I will look into it. Mastodon might have some good concepts in it that I want to look into and also come up with some standardised way for richer content that creators could provide beyond RSS to make it more palatable and easier consumable for users.
tl;dr not much this month :)
I'm thinking about creating a brilliant.org clone (the old version, not the current enshittified one) but entirely community-driven and open source: Besides the classical features (create/delete,edit your own problems) you can also have courses and collections: courses are a ordered sequence of lessons and problems, lessons are post-like entities that can contain text, images, animations, embedded videos through links, latex, code, ... Collections are just a ordered sequence of problems (ideally it is a progressively difficult path of problems, but this feature can be used for anything you want). It would also feature a wiki, and eventually a forum for discussing/administering the website.

I'm soon to beta my first macOS app: AlgoMommy.

Working on a visual language learning app called Snapalabra!
The idea is simple: You look at an image and describe what you see in your target language. That's basically it!
My reason for building it was that even though I can understand a lot of spoken spanish, I really struggle to construct sentences on the fly when speaking. Doing a few minutes of active learning like this each day really helps remap my brain a little, and I quickly run into situations where I hit a wall and realize I actually don't understand something as well as i had thought.
The app also gives a little feedback on what i have written from an llm, and it also provides clues that I have mapped to each image.
At the moment I am using it mainly for intermediate Spanish and beginner Irish, and personally I find it really helpful for both. Basically learning vocan for Irish, and more serious sentence structure etc. in Spanish.
I know a lot of people absolutely hate the idea of mixing LLMs with language learning, and I can kind of see why, but I personally find it really helpful in certain cases. If you are already doing classes, and consuming content in your target language I think something like this will be really helpful for a 5 minute coffee-break type activity in the morning. Its not a language course and I have not intention for it to be one. Its just a supplementary little tool that helps with getting your brain thinking in a new language and it is free to use.

On and off, I am currently coding a minimal wayland compositor for linux and AMD GPU(no libdrm), in RISC-V assembly (64bits), which I run on x86_64 with a small RISC-V machine code interpreter written itself in x86_64 assembly. I do not use ELF, but a file format (excrutiatingly simple as such file format type should be on modern hardware architectures) of my own with an ELF capsule (also written in x86_64 assembly).
I start with SHM memory, will add linux dma-buf once SHM is enough up and running. Currenty monothreaded, ofc. AMD GPU code for SHM is in, now writting wayland protocol code to please the first wayland clients I would like to run (not using the C libraries provided by the wayland project, native wire format).
I want to move away from x11, and once I get something decent with this compositor, I will probably have to fork xwayland in order to make it work with this minimal compositor, that for some level of legacy compatibility (steam client/some games).
In the end, I did design some kind of methodology and coded some SDK tools in order to write a bit more comfortably RISC-V machine code programs in a very simple fire format (only core ISA, not even compressed instructions, no pseudo instructions, using only a simple C preprocessor).
Coding time does not matter on such software in the light of their life cycle once it does "happen".
All that presuming not too much IRL interference... yeah, I know this is excessive to expect that...
The super hard part is not coding, it is motivation: energy, mood, cognitive bias, etc.
I'm not working on anything at all. I'm stuck in SAFe planning meetings for the next week. I fucking hate the whole thing but they pay me to sit there and watch others play with their Miro boards, so Merry Christmas you filthy animals.

I’m building a netsuite competitor (having spent a lot of my career on accounting and erp implementations.)
The trick (one trick) is to allow LLMs to provide an audit/accounting/compliance playbook, along with customizations, based on the user describing their business model.

We are building a K8s management platform based on AI Agents and smart visualization. It's surprisingly hard to distill common issues down to generalizable agents which can solve real world issues but we've made some very exciting progress in the space.
I run a small logistics platform called Twinjet that is used by mostly food delivery courier companies. One of our main features is parsing emails from food ordering platforms in order to automatically add the delivery job to the company's dispatch board. These parsers need constant maintenance since the ordering platforms change their email formats all of the time.
I'm putting the finishing touches on an AI parser that I hope to ship after the new year. I'm getting very consistent results from Ministral-3b model, which is super light weight.

It was a mud style game in beta that ended up getting axed in the early 2000s (?) but it was brilliant and a few of us stuck around in it long after we should have.
If anyone has heard anything about it, let me know!

In the time-honored hacker tradition of added more problems to the problem i'm trying to solve I'm learning a new language (never done FP before, either), building the product I wanted, using the latest crop of creative tools, and treating it as a little end-to-end business startup too. Launching in January!

I'm working on headless browser fingerprinting.
We're focusing on "anti-cloaking" for anti-phishing and other Internet security applications at the moment. Phishing sites can "cloak" themselves so that they present malicious content to ordinary users and benign content to bots, and thereby evade detection. Anti-cloaking is doing things to defeat cloaking.
The methodology is to operate a site that logs all requests, and collects information from the JavaScript environment, and looks for signals that a session is being operated by a bot instead of a human. We have 183 unique signals so far.
We've seen fake mobile phone APIs being injected into the DOM, and have been able to read out the source code implementing them. We've seen lots of people running the browser with TLS validation and same-origin policy disabled, which are both easy to probe for. And we've even seen people running services on localhost with CORS headers that allow cross-origin requests, allowing us to read out their server headers and page contents and which would allow us to send arbitrary requests to their local servers. We've seen people using proxies that don't support websockets. We've even seen surprisingly-big companies scanning us from netblocks that just straightforwardly name the company, which would be trivial to block just by IP address.
It turns out that every security vendor that scans VirusTotal submissions or domains from CT logs has major flaws in their headless browser setup which mean it's worryingly easy to cloak from them.
I don't know the best angle for monetisation. Currently we are selling "quick overviews" of what people are doing wrong, but it kind of feels like we're giving away too much value too cheaply. However it's difficult to convince people that there is value worth paying for without telling them what they're doing wrong upfront before they pay. Ideas include:
* automated quick overviews, where we give you a URL to point your bot at, find out all the signals you hit, and give you an automatically-generated report of what you are doing wrong
* or a manual "pentest" of your headless browser, where we do the same thing but spend a few days manually looking harder to see if there are new signals we're not yet spotting automatically
* or we could sell a report of the state of the industry as a whole
* or access to our tooling
* or something else
I have been told that if I say it's for anti-phishing then I have 12 customers max but if I say it's for AI browser agents then someone will give me a billion dollars. So possibly we need to explore other applications, like either telling AI scrapers why they are getting blocked, or else helping sites block AI scrapers (though I am personally opposed to building the apartheid web).
Open problems are:
* what's the best form to sell it?
* how do we satisfy people that if they pay for a test then they will get value from it?
* should we pivot away from anti-phishing?
* for bots that we notice have found us from VirusTotal or CT logs, how do we work out who is operating them so that we can sell to them? Sometimes attribution is easy but in the majority of cases it is not
I cannot say what I'm working on because it will be downvoted. Only pointless gimmicks which do not compete with the tech oligopoly can get any traction nowadays.
If I make a really good AI coding platform which saves people hours compared to existing platforms and provides more security. The chance of success is 0 because it's competing with incumbents.
If I make an app which allows cats to order food and back massages from their owners, this has a high chance of success.

https://github.com/connet-dev/connet
Just finished a major (v0.10) revamp of the API (you can use connet as part of an application, not through the CLI) which also fixed a few issues I've been seeing before.
Now, I'm gearing to update the relay protocols - currently relays are closed off by the control server (e.g. you ask it to provision you a relay resource) which requires the relay to communicate with the control server itself. In the new version, the relays will be operating on their own (there might be a shared secret with the control server, in case you want a closed off relay) and peers will reserve directly with the desired relays. Maybe in future, the relays might form clusters on their own to take advantage of better relay-to-relay network and peers will reserve only at the relay closest to them.
Another stream of work, is giving peers identities. Right now the server will give them an internal identity to better support reconnects, but these are not stable (e.g. they don't survive client restarts). In future, the peer will advertise their identity and then other peers may choose what peers to allow comms with and what to ignore, pushing more decisions into peers themself.
Yet another change I'm thinking about is exposing raw endpoints to enable users of the system to implements other protocols - I'm not quite sure if this is really needed (the destination/source, e.g. server/client) covers a lot of ground by itself, but it would be great if these are not the only options.
Many options how to continue, but if I'm out of ideas, there is always a Rust rewrite to throw in /s
Actually, I realized that I've used `/s` incorrectly. I've been thinking about rewriting the clients in Rust, mostly to allow simpler embedding in other languages - java and swift for example (I think it would be great if connet was available on mobile - for android you can Termux to compile/run it, but it is a pain). This will make it harder to embed in golang tho.
Another option is to try to rewrite clients in each of the language, but most fare poorly on QUIC support - in Java for example, I'm not aware of one that is advertised as production ready (looking at kwik with their fork of TLS).
