This starts from my frustration when opening large CSV files, but later evolved to a log/data analyzer that loads arbitrary format in constant time (O(1)).
The secret: I engineered an incremental combinatorial parser capable of processing customized format from a steam. Any inputs, including file or the stdout from a command, are first chunked and then fed to the pipeline. The UI is ready when the first small chunk is processed.
Other highlights:
2-mode filter, one with a convenient UI and the other is based on an extensible DSL for complex cases;
Timeline mode scrollbar, a secret weapon for log or time series analysis;
Column widths fit to content automatically;
Native code, no web bloat;
Cross-platform (currently Windows and Linux, MacOS WIP).
If you are tired of all the quirks Excel have when working with CSV files, you'll gonna love it!
Now the language / compiler itself has been working quite well and I've been dogfooding it for like six months now. The next thing is an IDE-style editor where you can import a song and write the notation following it. Making THAT has been quite the journey. Here's a screenshot for good measure: https://i.imgur.com/EmlqlrM.png
It's intended for drummers, but I wouldn't rule out anybody. It can generate sound, and I'm even using some nicer sounding samples I found on the internet, so using it for composition is realistic.
But the main use case I'm going for is my own: making sheet music for drum practice.
I’m developing X/D Loom (https://xdloom.com), a tool that helps car enthusiasts create automotive wiring diagrams.
About a year ago, I engine-swapped my Nissan D21 hardbody from the Z24 petrol to a TD27T turbo diesel and also installed a whole bunch of accessories, like spotlights, a winch, and an air compressor. But being lazy, I didn’t write down any of the wiring changes I made while doing all of this. So fast forward a year, and now I can’t remember how all the wiring works.
My current project car is a Jeep Cherokee FSJ, and for it, I want to build a completely new loom from the ground up. So to try and avoid making the same mistake I made with the Nissan, I Googled “create automotive wiring diagram”, but all the results were for complex enterprise grade solutions charging $200/month. That’s why I created X/D Loom as a project car guys' tool for creating wiring loom diagrams. It allows you to drag different electrical components onto a canvas, connect them with wires, and export them to a PDF or PNG.
We're working on Drawers (https://drawers.computer), a macOS app to give each of your projects its own dock, space, and windows.
We integrate with macOS spaces to switch out a project-specific dock on each space, containing only the resources you need for that project. We made it possible to add granular resources instead of full apps to the dock (think specific slack channels instead of the whole slack app), to keep the dock hyper focused on what you need.
We built this to stay focused while working on the computer, and we thought that the native interface mixed all our projects together, causing us to get distracted.
Yep! Each Drawer (project) has its own folder path. We have integrated apps like Figma, WhatsApp, Messages, and Slack to keep them focused on one project.
Would love to hear what you think we should add next!
I've shared this one before but I built a logistics management system to power deliveries for a business I founded years back and I've continued to refine it since:
Since the initial MVP, it's done close to 100k orders and I've added new functionality like:
- Intelligent order batching & route optimization that can interleave tasks across orders in such a way that they still have the best chance possible of completion within their delivery windows
- Further refined the mobile tracking logic in our driver app to improve the quality/frequency of position updates while continuing to be as efficient as possible on battery
- Numerous backend/DB optimizations such that average response times are in the tens of ms at the current volumes it's handling.
It's not open source but if you have an interesting use case and are curious about it, feel free to reach out.
With AI IDEs, Personally I had to generate a tons of md files for planning a task, analysis on the code for something or other, a task doc for a feature - a summary to paste into the clickup ... and I saw many devs keeps on generating them, and all tucked away into folders. Good, okay.
For the company I'm currently working I had made a VSCode extension where I can sync the task doc with clickup via frontmatter.
I decided to take it to next level as a side project. I built a CI integrated, git-native, agent template transformable syncing pipeline with git MD files to any project management tools. That means, either you can save your md files vanilla in your wiki (thus using the clickup AI search to dig up later, get insights etc) or you can use a AI agent template transformer to turn it into a task template (Background, acceptance criteria, functional requirements etc.) and update or create a task on a board.
I've been working on it now. I don't know how it will fare, but I feel like product is coming up nice.
Forbes just wrote an article about it which was a fun surprise! [1]
It recently turned 6 months old which is wild to me. My wife and I have made a new puzzle every day for half a year! I wrote a blog post about this [2]
I recently released user logins. That went well and a lot of people are using them. I also let you filter the backlog by completed puzzles based on player feedback.
This week I’m going to start releasing player submitted puzzles and release my puzzle building tools. You can watch a video for a sneak peek of those tools. [3]
Thank you for Tiled Words which I play regularly! I introduced it to a couple of friends and now they compete every day for the best time to finish :-)
While you're here if I could make a small suggestion - the wording of the 'type of' questions was confusing to me until I got used to it; 'stop' is not really a type of 'watch' for example, so maybe you could find a different way to phrase those? Maybe there isn't a neater way to encapsulate the idea of 'is a prefix or suffix to', I don't know, but I found it difficult. Anyway kudos to you and your wife, it's a great game!
Hey, that’s awesome, thanks for playing and sharing it!
Great feedback on the “type of” clues. I’ll need to noodle on that and see if there’s a clearer way to express it.
Maybe I should just be doing blanks… e.g. for “sun” it could be “___ dress, ___day, or ___ flower”
To me a "stop watch" is a type of watch, that's straight forward. But there are other clues that rely on cultural references I'm not familiar with - and that is, I think, inevitable in this type of game. We all have different backgrounds and there's no universal shared understanding that would make every clue the same difficulty for everyone.
I saw someone on here recently say they like to do the puzzle without looking at the clues, and I've started doing that on and off too, it changes the game in an interesting way.
I've been playing this since it was first mentioned on HN a few puzzles in. It's a nice idea and pretty well executed.
I have, however, rejected making a user login. I recognise you're putting in time and energy to make something I'm just taking without payment, and it's your right to try to leverage it into something more - I wish you all the best in doing so - but asking for a user login as a gate to a feature you clearly don't need a user login for is enshittification.
I'm implementing Raft consensus from scratch in C++ with raw TCP sockets. Right now I'm working on a high-performance RPC client and server to keep network latency to a minimum. The main purpose of this project is to hone my systems programming skills and get more comfortable with distributed systems as well. One of the coolest things I've learned here is event-driven I/O with epoll and how event-loop architectures work in asynchronous setups.
Being a weightlifter for 20+ years now, I'm working on a barbell speed and path tracking sensor based on newer IMU hardware technologies, which makes it both more precise and cheaper than camera- or actuator-based systems. Ultimately it helps you lift and train safer and better.
It's an intersection of industrial design, hardware, firmware, and software (and some sport science, of course). This intersection is not yet dominated by LLMs so it's a breath of fresh air.
In an early prototype stage as in "strap a Raspberry Pi to a bar", but it looks promising and I'm happy to move forward, also using connections from my previous 12+ years in China.
Wannabe powerlifter here of about 20 years as well. This sounds like an awesome project! Is bar-path the main metric for safety and "better" lifting? A project I had in mind, once upon a time, was an automatic "Form Check Friday" for myself using a Pi + Webcam.
Thanks! I think for "canonical" lifts (squat, deadlift, row, to some extent military press) the vertical bar path is mathematically optimal, and for all kinds of lateral or sagittal movements you do more work with weak stabilizing muscles and load joints laterally too. Is it productive work that strengthens your core? Possibly, but it's hard to quantify. It it something that can lead to injury? Absolutely yes.
For more complicated lifts like bench press (J-shaped) or snatch (S-shaped), for example, I would rather set a "golden sample" path with a coach and compare to that.
It's unlikely to be the sole metric, especially given the inverse kinematics of different body types (long/short femur, etc), but together with bar speed, over time, it can provide a lot of good feedback.
It is not "absolutely" something that can lead to injury. Injury itself is difficult to define, and often the reason one experiences pain sensation is multifactorial. Within lifting contexts, generally the factor which has the strongest evidence for injury prediction is how sharply an athlete increases intensity compared to what they have previously adapted to.
No offense, but this post does come across as you only having a surface level understanding of the field. Especially surrounding injury/pain perception, I would be more careful of what you assume is true, there's far more nuance.
As someone who has been very deep down this rabbit hole and hacked together multiple path and velocity trackers over the years (specifically for olympic weightlifting), there is no extra information that tracking bar path will give you that simply looking at the video won't, and often just adds more clutter. You don't need to graph bar path to see that the bar is looping too far forward after hip contact in the snatch.
Velocity on the other hand is a great metric to track and is used as a proxy for RPE. Mike Tuchscherer was the first one to systematize it for powerlifting a while back, if you've been lifting for 20 years you're probably aware of the name.
i'm curious about how effective path tracking can be in comparison with computer vision based inverse kinematics of the body itself. do all forms of bad form have detectable imu signatures?
i wonder if it would make sense to consider it as a data problem, capture a bunch of high fidelity inverse kinematics data for various forms of bad form/dangerous lifting along with the imu data and then work from there. there could be some interesting and unexpected features that are easier to detect than straying from straight line paths with some tolerance.
Side note: My LG Watch Sport smartwatch was able to determine what weight training workout I was performing and somehow figured the weight with astonishing accuracy.
I’m an application developer by day, but lately Claude Code and Codex have finally made microcontrollers approachable enough for me to start tinkering with them on the side. I built this little “holographic” display that shows the surf forecast for any beach. While my friend built the casing, and mechanical part of it
Its a pretty straight forward technique, the display is at the bottom and in the glass cube there is a mirror at 45 degree angle facing you (you can see the mirrors edge on the side wall) which reflects the image from the display at the bottom making it look like a hologram
I've just published my first book. The central argument is simple: software development is a design activity, not a construction activity — and confusing the two is the root cause of most project failures. Written for developers, managers, and anyone who has ever wondered why building software is so much harder than it looks.
It's on Amazon in both Kindle and paperback formats.
Working on the bigger product still. Existing solutions I've found in this space seemed lacking. On my website, I want people to quickly find the software they want to be kept up to date about (with a smart search bar that does the heavy lifting for them) and easily sign up for notifications for new versions. Hope to make a Show HN for it soon!
It's a short chain-reaction game in which you explode balls bouncing in the screen, and need to build up to target scores. You build bigger and bigger combos as the game progresses.
It was a blast to work on it, starting with a small toy and just adding features that "felt right" until I had a game that was fun to play. It was quite hard to find a balance though, so a lot of numbers are arbitrary - but I enjoy seeing people breaking the game in new ways and finding new builds.
These days I've been working on patching reported bugs and sharing the game with people. Now after the latest patch, I feel like I'm done, but I feel like going back at it and adding an idle mode. And maybe simplify the codebase so I can test and iterate better, and then add many more ball types...
I know that any good LLM could replicate this pretty quickly, but I made this myself and I'm still feeling proud of the accomplishment :)
I've been working on RVW, my adaptation of the standard transformer model that is capable of online continual learning without catastrophic forgetting. I finally published the first pre-print of my early experiments: https://doi.org/10.5281/zenodo.20064617
Now I'm working on expanding the work into more parameters and improving performance. I just finished an extremely harsh test of a Nemotron-flavored RVW that consisted of stretches of a random assortment of domains interspersed with long runs of single domains. Across all of it the model didn't forget (and actually improved on some of the more challenging domains). PPL on SmolTalk is still in the ~18 range, which I'd like to get lower, but this is all with only 4B params.
Currently, I'm training a Llama 3.2-flavored RVW with only about 2B params to see how that turns out. Depending on results of that, I may take it to Gemma 4 next.
Research grade orbital mechanics, specifically of asteroids/comets.
I've been working on it for 4 years now, finally tried using some AI tooling the last few months and ended up vibe coding a fun little visualization.
After quite a few years of coming up with and implementing 'great ideas' but not being able to follow through to making them revenue generating products, I'm on my best bet so far.
I always wanted to build a real-life puzzle game, which is app/mobile assisted. Had yet another eureka moment, and built a usable prototype (backend plus iOS app). Good feedback from a small circle.
For a while I was aware of someone (I knew by sight) who worked in the same sort of subject matter (but a non-tech). I approached her, we had a coffee, I pitched the idea and how she could bring it to life, as I made the tech side. She jumped on board.
We're two and a half weeks in, have gone full speed and are making something great (for our audience). My future co-founder is amazing, great insights, opinions, drive. We're potentially launching in a couple of weeks, a free/MVP version of a puzzle game.
I've been through many iterations of trying to get something off the ground. Tried tech co-founders, and the last years of going solo (very hard after you've done the coding). But this now feels right. A puzzle app/game for every day people to have some fun. And a future co-founder whose life is outside tech, who's bring a sort of fun energy outwith let's make loads of money or isn't the framework/AI cool.
Balance is good. Contact with reality is good too :)
I’m building a blackjack card counting tool for people to learn how to count and how to identify games that are winnable. It is designed to take a completely novice to an advanced, winning card counter, using a Duolingo like approach - mastery based learning across sequential modules. Minus the ads and dark patterns.
That sounds super cool! When you say Duolingo do you mean spaced repetition? If yes, have you identified what type of spaced repetition approach you will take?
You play by setting rules onto a small grid of numbers to maximise your score.
My focus the past few weeks has been on refining the difficulty by experimenting with different rule types, and improving the UI.
I'm pretty happy with the look and feel now but feedback is always welcome, and I'm especially keen to hear what you think of the level of difficulty of the puzzles. It's a tricky balance to introduce variety without adding complexity.
There's a (very) small contingent of daily players now which is really motivating.
Float-explorer, a tool for generating very precise assembly programs to explore the darkest recesses of floating-point behavior on your processor without having to bully the compiler into generating the code for you.
And when I say darkest recesses, I'm not referring to "0.1 + 0.2 != 0.3" (which is fairly well-known) but things like "so when you turn on denormal flushing, how exactly are you defining it because there's at least three different definitions..." Or also "does my emulator actually emulate floating-point behavior correctly, or is it delegating to the current hardware which might have a slightly different definition?"
I'm making a program to build Magic: The Gathering decks from first principles of card data, no reliance on user-posted deck aggregation or EDHREC, and no AI. A slew of internal knobs exposed.
I do calisthenics 3×/week plus Ironman 70.3 prep, which means my training lives across Garmin, Polar, Withings + FIT files and front-lever sessions that no mainstream app models. So I built one that does both (and have been using for the past 4 years+): logs custom strength moves (front lever, FLAC, ¾ pull-ups), aggregates the connected devices (Polar, Garmin, Suunto, Withings, Apple Health) into one weekly view.
Currently trying to see if can integrate some AI insights to my training routines.
App is free for now as it does not cost me much (only servers for now), comment / use cases welcome: https://obitrain.com/
Have you seen that meme template, where the midwit wants to use a thousand complicated things to optimize their experience, but the grug and the genius both keep it simple?
I think this is a perfect example... somewhere out there a genius and a grug are happily exercising together for the simple joy of doing so and feeling good in their bodies, and nearby is a midwit with the GDP of a small village worth of wearable electronics wondering where the joy has gone as he laments the 0.1% of VO2MAX he's dropped since his last gadget-run.
I haven’t trained for an Ironman but have for a marathon. I do think some metric oriented work is helpful! But I laughed at your post. Happy to see both sides.
In this case it might not be as complicated as it seems, they might be using a Polar device for workout tracking, Suunto for marathon training/hiking, a Garmin as daily watch (payments, music etc). Add to that a Withings scale and an iPhone, and you're dealing with a melting pot of apps.
my embroidering is going fairly well now, but i need to be able to figure out what floss to buy.
the general idea is to take pictures of birds and mountains, and use a bunch of colour-theory-from-minecraft
to first meanshift a bunch of the image to come up with a lower colour resolution image, then to match that to dmc threads
but then i also want to use tools like the axiom mod to fill in gradients, and to do hue shift/temperature changes to represent shadows, like how bdouble0100 uses purples as a shaded green, rather than a darker green.
ive also been using it to see how the claude code for web setup works, and it feels real poor compared to the cli.
the main problem i think i need to pull to local and do my own code for is the colour sampling from the oklab space. when i try to create gradients from colours already in the list, i ve got a visualization of the line its aiming to follow, but its picking the next colour and placing it out of order vs projecting to the line.
likely my biggest issue is that claude and the like are still bad at thinking in more than 2 dimensions, but i think my vocabulary is also subpar for giving the feedback either in clear linear algebra or colour theory terms.
next idea is for when thats done is to make a mod that turns a survival game into a roguelike - in the style of the hades 2 challenge runs, so i can play a session of the game in a certain biome without having to do all the grind first to get there on a new character.
Just implemented Landlock + seccomp notify based sandbox in PMG. A tool to protect cli package managers against malicious packages. There were quite a few quirks involved due to Go routines when it comes to handling messages from the kernel.
It's a durable orchestration system for AI code generation which solves the problem of not being able to trust LLMs to complete long running (and high quality) implementations without having to babysit them and monitor the process, which is what I think is the most exhausting part of coding with AI.
You start with a spec or programmatic task list and the engine runs the whole workflow: implementation, verification, review, fixes, and finalization.
It treats agentic coding like a durable CI-style process, with state, retries, reviewer feedback, commits, and auditability built in. It's externally orchestrated, meaning it's not the agent running the loop, it's simply agents being used as tools and spawned in the loop as needed without awareness of the loop itself.
It's going to be open sourced soon and it's not meant to replace your IDE or Agentic Harness of choice. You keep using codex/claude code/open code/cursor/pi whatever you want and simply delegate the actual implementation to the engine, through MCP/CLI and other integration points.
It supports any LLM provider so you can have GPT 5.5 implementing and a mix of Opus 4.7 / Deepseek v4 Pro / GPT 5.5 reviewing at every phase for example.
I'm working on a general repo shape/structure linter (language agnostic)[0] - the idea is to enforce things like directory structure, existence of various files (LICENCE, etc.), file naming patterns, jsonpath + schema over json/yaml/toml, absence of potentially malicious unicode. It comes with rule bundles for various languages/presets which can be combined and extended. A goal is for it to be very fast, and useable on huge monorepos. I noticed myself having to add various forms of validation/scripts when coding using AI, and decided to build a reusable, fast tool for this purpose instead of rolling validation scripts for each project.

These embed a remote browser in an iframe to give you “embed anything browser view” custom elements. The demos focus on retro desktops to emphasize the browser - as these common web tropes, the retro desktop, can never actually ship a real browser without something like bbx.
Acoustic diagnosis of electrical problems on the electric grid!
I'm building a tool that allows you to determine the health of an electric transformer from only your phone. It tells you:
- the loading
- the health of the windings and core
- and whether the phases are unbalanced
I used to be a submariner, so my professional background is in power plants and sonar analysis, so I'm getting to combine the two in this.
Acoustic diagnosis of electric issues is FASCINATING, and it feels like there hasn't been a lot of research into this, so I have been slowly chasing down various acoustic patterns I find and try to derive them from first principles of physics.
I'm making an iPhone app for it, and Xcode has been truly awful: non-deterministic, crashing all the time, and error messages that tell me absolutely nothing. I would like to use xtool, but it doesn't have the preview, which I need for debugging.
It's a little web application that allows for the ranking of all kinds of abstract entities. Think of the merging of Goodreads for books, Vivino for wine, Letterboxd for film, etc. This will allow you to instead rank whatever you want across a variety of different categories in a single place.
Using your rankings across all these different fields, you can draw analysis of what you like, and in future I'd like to add a little personal (not an ad) recommendation engine to help you find new stuff based on your actual interests across loads of different categories.
From a technical point of view, its been a great learning opportunity on how to fully host a complete stack using an opiniated, but cross-platform orchestrator, allowing me to host this wherever (bare metal VPS, homebrew system, cloud provider) in a flash.
I made a Python tool to build distroless container images for projects managed by uv. It draws inspiration from Ko from the Go ecosystem and works with/depends on uv from the Python ecosystem, so I smashed them together and called it Kuvo: https://github.com/hxtk/kuvo
It’s a hobby project in a very early state where it technically works but it’s missing several things I think it needs before I’d use it for anything serious. As of right now it isn’t even complete enough to dogfood a minimal container for itself without an intermediate base image because it can’t target a platform compatible with the distroless uv container image.
I'm working on a diffusion-powered UI design tool. My short term goal is to make AI-designed UI not look like Tailwind. My long-term goal is to be Figma, but powered by diffusion.
I quit Figma about 4mo ago to start working on this, and the gpt-image-2 drop really legitized the bet. I recently release Brands for diffui, which let you establish a design system and consistently generate with it. I made a Brand out of the recent UFO files release, which allow for some really fun designs:
It works on MacOS, built with Swift and Metal. My goal is to make a super fast, and free, focus stacking program. I provided a notarized MacOS DMG for the initial release, but if built yourself, it will run on an M4/M5 series iPad Pro as well.
The core ability I wanted was to support RAW files as inputs, with DNG files as outputs. This is done using either LibRaw, or Adobe DNG Converter (runtime options).
I have been really into macro photography the last couple years, and have been slowly working on trying to build my own program to handle the focus stacking.
Very cool! Do you know Thomas Shahan's work? He once contributed his woodcut artwork to a videogame, so he does seem very technically curious. I bet he'd be interested in trying something like this out with his own work and providing feedback...
I'm mostly diving head first into formal methods again. Mostly TLA+, but a bit more Isabelle as well.
I haven't really forgiven myself for dropping my PhD; I think it was the right decision at the time, but I also kind of wish I had pushed through it. I'm going to see if I can at least get a few papers published.
I've also had some fun getting Claude to create LSP servers for different languages, which it has been pretty good at, and that's nice; having good integration with Vim makes a language a lot more fun for me.
I continue to be working on kei, my cloud->local photo/video sync engine.
iCloud Photos is fully baked along with implementing their completely undocumented SyncToken. I’m doing some QoL work in the next few weeks, tightening up some early architecture decisions, and then adding more providers (Immich, NextCloud, Google Takeout… else TBD).
Since last time I posted this, two other people contributed and I’m almost at 100 stars! That’s some dopamine.
I wanted a faster, easier mapping app to plan motorcycle rides for myself and with groups, so I finally bit the bullet and started building my own at the beginning of this year.
I got to the MVP state which was useful for my personal use case in about a month. I took it further than that as a learning exercise and as a means to share it with others. Some features that came later are live cursors (like Figma), elevation chart and grade overlay, and QR-code enabled collaboration links to make in-person sharing simple.
Figuring out the exact UI/UX I wanted was the hardest part. I did the branding myself, handdrawn on paper, traced in Procreate, and vectored in Sketch. Fast iterations and a good test suite made it possible to try lots of different approaches and refine the one I liked the most. There are roughly 4000 unit tests and over 300 e2e tests that run on multiple environments with fully automated CI/CD.
I’m using Mapbox for the frontend and the whole app is basically just a monolithic Cloudflare Worker. Claude pretty much implemented the entire thing. I got a lot of mileage out of self hosting a Gitea project and recording all my planning sessions as Milestones and Issues. Claude has his own account without admin privileges. The process of managing a team of agents to build this practically autonomously was a bit jaw dropping and eye opening to be honest.
I would love to hear from other pleasure & sport drivers about the features they use or want the most in a routing app. I have an Android app in Play Store review, if you’d like to be an early access tester shoot me an email at my handle @plotalong.app
Very nice! Does the sharing feature allow live location sharing? That seems like it would help a lot, especially when group members are in separate vehicles.
No, and while that does sound like a pretty obvious feature I should clarify the app is about planning, not turn-by-turn directions. You can open Plot Along routes in Google Maps, Apple Maps, multiple GPS formats and more
The idea is everyone opens the same route for coordinating and there’s just one source of truth for the group. And then when you’re all about to hit the road, everyone can use the nav app they’re already familiar with (or that’s built into their vehicle)
I will tackle the navigation aspect at some point if I do keep up on feature dev, though!
I've been building this "general problem solver" (will likely focus on math problems first) that uses a special kind of orchestrator to direct/structure the problem solving approach in accordance with how many 'rounds' remain and other aspects of problem context. It does this largely by influencing the behavior of specialists.
You initialize the system with an objective and a number of rounds to run for, and it loads the current config (orchestrator + specialist prompts and LLM configs) and begins working on it. You can manually step one round at a time or just let it run.
Rather than accumulating a single long work log/context, at each round specialists apply patches to a number of named 'artifacts' with different roles (e.g. uncertainties, dead ends, findings), which are injected into prompts during subsequent rounds.
The engine is written in rust and there's a web UI (and CLI). You can use the built in config editor to define specialists (and their prompts), what the artifact set is, orchestrator prompting etc.

I got most of my must-haves for my car maintenance tracking web app out of the way. it already does everything I wanted all the paid alternatives to do, even has SSO integration (only Google OAuth for now). the other must-haves, I do actually need, but I think they can wait. notifications, and an export mechanism for my history (including file attachments). for now I think I'll focus on the other things I've been putting off, like upgrading my car's audio.
Still building https://FastComments.com :) I'm planning on launching a desktop app for it soon with a combined forum. So you could have a community on something like discord, but all the chats are indexed and searchable through a web forum style interface as well. The desktop app is a native C++ app so no electron :)
I'm also working on launching https://watch.ly (network/fs sandbox with human in the loop for ai agents), mostly waiting for the entitlements from apple at this point...
oh and I launched https://dirtforever.net recently to keep Clubs going for Dirt Rally 2 without the EA servers. Learned about the egonet protocol and made a server.
working on https://heylife.ai, an app that gives you proactive advices based on your calendar/taste/hobbies/location
let’s say you are arriving in paris. it will send you advice on how to get to the city from the airport. big soccer game in an hour? will send you advice on prepare it.
you don't need to ask, it will give you before / when you need it.
now working on the sandboxing and scheduling of the advices. releasing it this week if anyone want to give it a shot. (it will be paid only)
Continuing to work on Tab Wrangler, an extension for both Chrome and Firefox that has been available and open source for 10+ years. It auto-closes tabs when they have not been active for a configurable amount of time, similar to the feature built into Mobile Safari but more configurable.
I have been maintaining it and in the past few months added features that had been requested for a long time.

I'm actually looking for beta users! GetSetReply is a SaaS I've been building. It does two things for small businesses:
1. It helps you get more reviews by sending automated requests for reviews to your customers over SMS and/or email after they purchase from you (PoS Integrated / Manual Sending)
2. The second is helping you reply to the reviews you already have with AI-generated drafts in your brand's voice that you can send to Google/Yelp/TripAdvisor.
I'm very grateful to anyone who is willing to test or provide feedback. If you create an account (it's free with no credit card or integrations required), I'll reach out! Or you can email me via my email in my profile.
Fitting lines to 'xray' scans of buildings - turning pixels into vector art.
Lets say you have a complex industrial plant, or datacenter you want to upgrade.
You scan it with lidar and get a pointcloud and 360 panorama images.
This gives you a large dataset, but what you really want is a floorplan, a lite CAD plan showing the racks, cable trays etc.
You take the scan, slice the pointcloud and make an ortho image .. it really looks like an xray of a building from the top down.
Then someone has to manually trace that in CAD to make a useful 3D model they can use for designing the upgrade.
So Im automating the boring manual part - turning the xray plan pixels into vector polylines, using machine learning.
One of our clients scanned their datacenter, and we generated a floorplan that shows all the rack box positions, cable trays, pipes etc.
Other examples : drawing the weld lines of patches in steel storage tanks, drawing in all the steel girder beams in a scan of an old railway bridge, or the windows, doors, ceiling pipes of a commercial realestate refurb.

As part of this work, were looking at running our custom machine learning kernel on multi-core x86 CPUs.
I've been using https://github.com/gchamon/buzz as an opportunity to have a WebDAV with tight integration with real debrid, jellyfin and opensubtitles. It solves the requirement of jellyfin for having a single file per folder even if the original source had many files in them, adds confirmation for removing entries from debris, has an archive so deletions can be restored, a simple but powerful integration with opensubtitles and a functional logs UI. It's also an opportunity for me to review web design concepts and experiment heavily with coding agents, both local and SOTA.
I'm working on requested features for my social wishlist app https://thingstohave.app: image uploading, passkeys and more clear list organization UI. Everything is in polishing stage, and I hope to release these before June.
Big thing I made recently is moving it from SvelteKit to Hono + Inertia + Vue.
I like SvelteKit, but I was struggling with stability in active development periods, and writing proper tests was very hard due to mocking all the magic, especially outside trivial testing tools.
Now the whole app is straightforward Hono MVC with Vue powered UI. Logic is easy to test, and all UI states exposed in Storybook.
I wrote a custom adapter that makes Inertia run on Hono, and coincidentally same thing was released by Hono author itself as official module, which is great sign for adoption!
So, try Inertia – it is a best of both worlds. You write MVC backend as you like, and use modern JS frameworks for templates.
I’ve been building an uptime monitor service for a while now, something that is genuinely reliable and only alerts you when something is actually going on. Also comes with very pretty status pages!
Free tier is enough for most users, paid tier just exists to gate the stuff that is expensive to run like SMS alerts.
Building a community-oriented platform for maintaining morphological descriptions of organisms + guides to identify them based off a shared vocabulary.
Been working on it on & off for a couple years, usually taking breaks between refactoring stupid decisions.

Prod site is pretty behind dev branch, basically abandoned normal CI / repo hygiene for the moment
I've been working on an update to my flashcards app for over a year and half now and I'm finally nearing completion. This is for Mac and iOS only and the app uses Core Data with CloudKit for syncing its data, which has been interesting learning the ins and outs of. (For instance, CloudKit can throttle your sync if you have too many objects, so I ended up having to create snapshot objects to carry lots of records in bulk which I then expand in a local SQLite database to get around its limitations.)
The app has a lot of UX details that I've really enjoyed working on. I wrote up some notes about it here: https://www.freshcardsapp.com/3/
Separately, also working on a Zettelkasten notes app that pushes you to make small, atomic notes that you can organize in "collections" to provide structure beyond just hyperlinking in the note text: https://understory.ussherpress.com/ This has been a lot of fun iterating on. I started with a Miller Columns UI, like Finder, to visualize the graph of connections between notes, but I found that it was too overwhelming to use, so I scaled back and went with a more Notational Velocity-like quick search bar with note addressing. The app UI mimics a browser because I found that it works really well for something like this. I need to polish it a bit more and want to find people who will give it a beta test to help me iterate on the ideas some more.
I am hacking on an alternative to Builtwith: bloomberry.com. Unlike Builtwith, you can search for companies that use any backend/backoffice product such as Jira/Atlassian, and Github (enterprise/free).
It's an iOS & Android app that applies various generative art effects to your photos, letting you turn your photos into creative animated works of art. It's fully offline, no AI, no subscriptions, no ads, etc.
I'm really proud of it and if you've been in the generative art space for a while you'll instantly recognise many of the techniques I use (circle packing, line walkers, mosaic grid patterns, marching squares, voronoi tessellation, glitch art, string art, perlin flow fields, etc.) pretty much directly inspired by various Coding Train videos.
I'm currently fighting Garmin's wonderful Connect IQ watch app platform (it's horrendous).
I'm working on <https://untether.watch>. Trying to shift 20-30 micro phone interactions to the wrist per day to ultimately reduce phone use. Dumbphones are too extreme - you need a smartphone for certain day-to-day activities (banking etc.)
The watch is a great form factor - it's got a crap screen (MIP), the ergonomics are awkward (rotate and look down), it has limited capabilities. But that's the point! Do essential quick actions and leave the phone out of site.
Requires Android companion app to do the heavy lifting. Use the (head)phone mic and STT to reply to any android notification and make notes. More features to come.
Garmin's SDK is seriously challenging. APIs are often broken across firmwares, limited developer tools and testing is tough.
It's an SDLC workflow harness for agents. Instead of using skills to encode my typical workflows (e.g., create PRD, then create plan using TDD, then dispatch subagents, etc) I've built a concurrent event-sourced process manager to handle it.
I was tired of copying/pasting between agents, so I gave them identities, and tools to talk to each other and share tasks. I've found it so useful that I've left my job as the CTO of a German startup to focus on this.
The identities are public-key DIDs with DNS as the source of truth, as well as team membership. I also run a public registry at https://awid.ai (also OSS).
Docker is...quite slow with large images. I've built a registry+pull client+buildkit builder to make it better. It splits apart layers, allowing for files to be shared between related images. In a robotics context, it can make pulls 10x faster. And in a cloud context, the format allows for pulling an image in 15 or 20 seconds instead of 60, without having to do a FUSE w/lazy pulling. Builds are faster, I store 7x less data due to better deduplication, I can run security scans faster due to not having to unpack tarball layers, etc, etc. I want to be the default registry for all ML related work, in the future.
I'm working on MedAngle, the world's first Agentic AI Super App for premed, medical, and dental schools and recent graduates - young doctors.
MedAngle is literally everything one could need, personalized to their curriculum across 4-6 years of medical school. Quizzes, videos, notes, flashcards, reminders, scheduling, performance, search, and more.
Our Super App is comprised of MedGPT + MedAgent + Spaci (futuristic spaced repetition), which serve as layers over our massive collection of features such as the Smart Suite, Learning Library, Clinical Corner, Tested Tools and more.
100k+ users, 10s of billions of seconds spent studying smarter, invite only. Bootstrapped, growing nicely. I lead a team of top medical students and doctors.
I'm working on an AI-native email client that organizes, prioritizes, and drafts emails for you.
The vision is for everyone to have an executive assistant that manages their email. It's built for people who spend hours in their inbox every week.
It has automatic prioritization, split inboxes, snippets, bundles, automatic follow-up reminders, and an AI agent that can do stuff for you -- without deleting your emails.
If you've read this far, I'd encourage you to give it a try and let me know what you think!
It’s a self-hosted email marketing/newsletter app. The basic idea is: own your subscriber database, run the app on your own server, and send through SES/Postmark/Mailgun/SMTP instead of being locked into another SaaS.
Not trying to be “Mailchimp but cheaper”. It’s more for technical founders, agencies, and consultants who want a boring, controllable email tool they can deploy for themselves or clients.
I built on online multiplayer boggle game back in 2008 that somehow drew a lot of users, many of whom still play every day after 17 years. About a year ago I started a rewrite from scratch in more modern technologies but stalled out after getting to about 80% of the way there. A few months ago Claude enabled me to finish the remaining 20% and was able to relaunch mostly successfully! It's been tough though. I'm a dad with three kids and use Claude all day at my day job and my interest in working late isnt always there. But I'm eeking my way to something that hopefully can stay up for another 17 years.
I wanted to make it easier to quickly see/study trending articles on Wikipedia because they tend to make good topics to know before going to trivia night.
I've had the domain for awhile, but just made the app recently on a whim.
I use Wikimedia's api to get the trending articles, curate them a bit, add some annotations to provide some context, then push to deploy the static site.
I've had public dotfiles at https://github.com/nickjj/dotfriedrice for a long time but recently branded them and after having run native Linux for 6 months, I added a desktop environment based on using niri and Arch Linux.
It can get you up and running in a few minutes with an installer that can set up a new system or keep an existing system up to date. There's also a command line version that works on Arch and Debian based distros (including WSL 2) and macOS. I use it on my personal devices and a company issued MBP.
I'm not going to lie, I've been using computers for 25 years and this is the happiest I've ever been with using 1 machine for everything (software development, media creation, gaming, etc.).
Since getting laid off in Feb, I've been spending my free time polishing up my word game Gram Jam (https://gramjam.app).
I finally finished the (monumental) Svelte 4 -> 5 migration that had been getting dusty for the last year. This unlocked a higher performance ceiling for me to polish my animations and UX. Now I'm revamping my onboarding experience and taking another crack at marketing and promoting it. Last year, I was focusing on setting it up as a PWA and integrating Sentry monitoring and Stripe integration. All important stuff but not what got me excited about the process.
I've been pretty tied up with maintenance and admin work, and haven't gotten a chance to work on the actual game design in a while, so I'm very excited to return to that part of the project soon. I have ideas for new puzzles and modes spilling out of my ears and I feel like with LLMs my prototyping can finally keep up with my brain, now that I have a robust foundation for the game architecture.
I track wait times at the Berlin immigration office. I just added a graph that shows how wait times improve/worsen over time. I generate the SVG without any external dependencies. It was a fun exercise.
I wish I had more time for such projects, but since AI is now capturing most of the traffic, I am losing a lot of my income and I have to make up for it. It's a huge distraction.
I'm currently working on BetterCapture (https://github.com/jsattler/BetterCapture), which is a lightweight (~4MB size and low memory/cpu footprint) screen recorder for macOS that lives in your menu bar. It supports ProRes 422/4444, HEVC, and H.264 — including alpha channel and HDR. Frame rates from 24 to 120fps. System audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.
No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac.
I'm currently planning and designing a plugin system, so others can contribute new functionality without affecting the scope of BetterCapture itself - which should stay as small as possible.
- Building a platform where talented people can list the services and skills they're experienced in. Clients can book paid sessions with them directly through the platform, and once a session is booked, they both meet online to discuss, collaborate, or get advice based on expertise.
I'm working on World Watcher (https://worldwatcher.live). It's an interactive map of livecams around the world.
The idea is to have a better experience for navigating livecam streams that are publicly available on YouTube. There are a few livecam aggregators that include maps, but I never felt that any of them were satisfying, as they always require you to open new pages to watch the streams. On World Watcher, you can jump from place to place seamlessly.
You can also filter the streams by type of place or features, for example beaches or cams with audio. And if you don't know where to go, just try out the Explore button.
I've been working on my open source integration-platform-as-a-service (iPaaS) auth proxy. It provides an embeddable integration marketplace where users can connect 3rd party apps, and it provides a proxy endpoint to the host application to send authenticated outbound requests. That way token refresh, audit, etc stay with this system and frees the host application/agent/whatever free to just focus on the business logic.
Slapping together an image dithering toolkit to help with album cover stylization. Partly making sure I can replicate it down the line... but also finding an aesthetic, non-commercial motivation I thought I'd forgotten at work.
I've been working on something in the vein of a indie game for a little over a year now. It has been a passion project, but I'm starting to come around on showing it to people.
I am a big fan of Telltale style narrative games. I think Baldur's Gate 3 was the biggest revelation of this for me. Taking that branching dialogue and freedom of choice, and tacking it on to a fun combat system was just everything.
When text based GTRPGs started popping up, I found it hard to connect with them stylistically. I found that I needed the multimodal stimulus of visuals and audio. This led me to start building something, and it ended up being somewhat of a cross between a Telltale game, a Visual novel, and a TTRPG.
Orpheus (https://orpheus.gg) is a fully on-the-fly generated tabletop simulator, with graphics, audio (TTS), and the freedom you can usually only find at a real TTRPG table. That means you can play a sci-fi, fantasy, or even a modern setting in your campaign. The assets are made for you as needed. It runs in your browser so nothing to install or tinker with.
Getting the harness right so the AI GM can stay coherent and organized has been the biggest challenge. It took a lot of iterations to get it to a point where it could understand the scenes it was building as the player changed them.
I've built it to be played with either a keyboard or a gamepad so you can play from your couch. You can switch between them as you feel like it. There is a 3D tabletop for combat, full character sheets, dice rolling, lore tracking. I want it to be dense.
Mostly, I’m looking for people who want to try it, break it, and tell me what feels magical, confusing, boring, or broken. My biggest roadblock currently is that asset generation is relatively expensive. I'm currently mulling over whether a playtest would allow for a BYOK setup so people could try playing as much as they'd like, or if I should add turn limits.
You can join the playtest waitlist at https://orpheus.gg/ -- and I just setup a discord (https://discord.gg/pychWyzf) that I will use for early playtests. (Just me right now! Come hang out!)
Why not generate some asset libraries to help with some of the rote generation? You could theoretically serve the same asset for a pack of rats to multiple campaigns.
Yes! I am doing a lot of this where it won't break the illusion. Not everyone needs a unique innkeeper generated in every town, but I want to avoid that "Officer Jenny" effect like in Pokemon where she looks the same in every town they visit.
I have a private vs public flag for assets that I'm considering more unique or sensitive, at the AI GM's discretion. I'm using embeddings from there to try and parse if an asset already exists in the public pool or not, and reuse it if possible. The thinking is that eventually I will have pretty decent asset coverage on most standard campaigns. I can't account for people going way off book though.
I have an asset pipeline that tries to determine player intent and pre-generate assets before they're needed. That way we can attempt to hide the "load screens" like retro games did with elevators. I have a kind of sliding scale for player coherency, and if the player has too many "misses" on the pre-generation pipeline it will increase its requirements for when it starts generating.
I may have wildly over-engineered this but I love it. =)
I've been the DM of a weekly campaign with the same group of friends for nearly a decade now. Over the past few years, I’ve seen a lot of attempts at AI meets D&D, and most of them suffer from fairly pedestrian puzzles and stories, and don’t really compare to what a decent, semi-competent human writer can come up with.
I'd love to see a more modern day attempt at something like Bioware's Neverwinter Nights - which was designed so that someone could create a campaign, and then the game would provide the behavior, pathfinding, assets, and everything else with a virtual (or human) DM behind the scenes. You could still tell a human-driven story, but the engine would do a lot of the heavy lifting.
I agree, there is no way to perfectly capture a real table with your friends. This is more an alternative for when life gets in the way of meeting every week.
I think a lot of those attempts you mentioned try and brute force the problem or trust the AI too much on what to generate.
A lot of the same problems that AI coding agents run into also apply to this problem. You have to really manage context (avoid sending a novel at the model) and enforce strict rules in the "engine". The hard part is world building that is consistent without railroading the player and forcing specific paths. I have an agent (for lack of a better term) that manages arcs across each tier. World arcs (nations, factions), player character arcs, NPC arcs, individual scene arcs, and location arcs (towns, cities, dungeons, etc). By prompting all of these as tight, individual arcs with flavor and context peppered in as needed, you end up with stuff that is more compelling. It has to be loose enough that you don't railroad the player. When you decline that NPC's quest, down the road that might have changed the overall arc for a town in a meaningful way.
I won't pretend that I've perfected anything but I have definitely noticed a spark in its writing and world building that I personally have really enjoyed.
Yeah I'd agree that I think AI can at least work provided you manage the context properly, multiple top-level files establishing consistent world state, all that jazz. KoboldAI and SillyTavern both do a pretty good job of maintaining internal consistency around longform interactive fiction.
OTOH, that means that the underlying story is that much more important. I think a lot of people mistake coherence for novelty. Biggest offender is puzzles - oh god do LLMs absolutely blow dire wolf chunks at coming up with organic and interesting puzzles.

We're working on AI user testing, to make it dramatically faster and cheaper for product managers and dev teams to find major usability issues with web sites. Give us a web site and a task users would do (e.g. "Add a pink shirt to the shopping cart"), and we have some AI users try their best to do the task. The output is a report with a prioritized list of problems identified, plus narrated videos that show each AI user trying the site.
If you want to try it out, we offer some free credits at https://fuguux.com
Any feedback you have would be incredibly helpful! We're considering more kinds of reporting, support for QA testing, better integration with CI/CD, and more.
Note: we don't want to replace real user testing, but rather complement it. With AI user testing, you can get quick feedback on potential usability problems in hours for a fraction of the cost, making it so you can iterate much faster. We advocate doing user tests with real people to understand problems that require domain knowledge or nuance.

For the past 2.5~3 months I've been working on a 2D/3D VFX (visual effects) editor dedicated to mac and iPhone/iPad, it was on my never ending list of fun projects to build and a perfect excuse to learn agentic coding on a domain of expertise (written in Swift/SwiftUI and Metal).
It’s a project of the non profit Open Transit Software Foundation that we’re using to fund our other initiatives, like bringing realtime transit information to billions of people around the world.
All of this depends on a bunch of really cool open source projects we’re building, like Maglev, a Golang server that can power realtime transit apps. I wrote up a blog post explaining how to set it up here: https://opentransitsoftwarefoundation.org/2026/04/setting-up...
There are several different ways that OBA can be deployed and used for a transit agency or a group of transit agencies in a given region. I'll give you four examples, but this isn't an exhaustive list:
1. The Puget Sound region, where a regional transit authority, Sound Transit, currently maintains their own OBA servers on behalf of a dozen individual transit agencies. Sound Transit piggybacks on our official OBA apps which you can find in the Play and App Stores. The official apps also work in 10 other cities across the US. This is the ideal for us—and transit riders, imho, and similar to what you see with apps like Citymapper or Transit.
2. New York City, where MTA runs their own OBA servers that power their own branded app and realtime signage throughout the five boroughs.
3. UC San Diego, where the university is using OBACloud to power real time transit information systems for students on campus.
4. Republic of Cyprus and Malaysia (yes the entire countries), where enterprising individual developers have set up their own OBA servers to power realtime transit information systems for their fellow citizens.
The underlying OBA server provides a rich set of REST APIs that make it much easier to build a public transit app than using raw GTFS and GTFS-RT data: https://developer.onebusaway.org/api/where/methods
We also have SDKs for many major languages so that agencies and independent developers can build their own apps on top of OBA servers without having to fiddle around with the intricacies of our APIs. https://developer.onebusaway.org/api/sdk
~~~
Integration with Google Maps is important, and a "yes and" solution. I think there's a lot of value in having public transit-focused apps, especially ones that don't have advertising or questionable privacy issues.
~~~
edit: I noticed you're in Argentina. The Ministry of Transportation maintains its own white label version of OBA called Cuando Subo. https://www.argentina.gob.ar/sube/cuandosubo
The Ubuntu DDoS got me to thinking: If we had a critical need to respin machines (like our data center caught fire), we would have been in for a real challenge. We run apt-cacher-ng, but it did nothing for us during the DDoS, and worse: Every few weeks or a month ac-ng will go out to lunch and we have to fix it.
So: ac-ng didn't reduce the impact of the DDoS, but it does lead to impact when there is no DDoS. Worst of both worlds.
So I'm working on an apt-cacher that goes to lengths to keep working as much as possible when the upstream is down. It will check the repo metadata and keeps a list of your "hot packages", and will download those before flipping the new metadata to be live, effectively a snapshot. It won't allow you to download a package you've never downloaded before in the case of a DDoS, but packages that you do download regularly (machine re-installs, apt updates), it will ensure are available in the repo.
I'm calling it apt-cacher-ultra. It is pretty early days, it'll probably be another week before it's ready for a beta. I'm running it in my dev cluster right now, successfully.
Working on https://kapturekafka.dev, a desktop app for Kafka protocol inspection. Think Wireshark or Fiddler, but native for Kafka.
Useful to debug local Kafka apps against any cluster, intercepts the traffic, decodes the protocol. You see interesting (and weird) things when you look at the protocol. Still early, though already useful for local debugging when you know what you want.
I'm newly mostly-retired as a VFX software developer & CTO. I'm writing about AI, climate change and more in my blog, https://oberbrunner.com, running Long Now Boston (https://longnowboston.org) to promote long-term thinking, and working through my lifetime backlog of "wouldn't it be great if somebody wrote this" ideas using Claude, at https://github.com/garyo.
You should check out my new open source software build tool, https://pcons.org.
I'm working on a Personal / Family travel organizer. Started as tool to allow me and SO to plan a trip together. There's been steady progress over the last couple years. Focus on privacy and ability to self-host. Of course, there is a managed version if one doesn't mind me having access to their data.
Interesting! Maybe making this info avilable to local LLMs would be useful too. Side thought: when we plan big trips I tend to pre-populate google maps with loads of markers of interesting points. I would love to be able to save this offline and combine them with other sources like youtube/instagram clips offline somehow.
You build up a library from your physical books by scanning them in or discover OpenLibrary books to read in app. Then as you mark books in your library as read, it starts building a rotation and recommending books you haven’t read recently. I’ve been using this nightly to track my son’s 1000 books before kindergarten for the last couple of months.
Currently, I’m working to get the app out on Google Play and adding multiple story time attendee support.

A model framework for an in house suite of models.
From dataset harvest, to training intricacies on CUDA/ROCm to fun HIP kernels. Full circle to inference testing, building it around consumer hardware(the challenge). Using this as a "how it works" deep dive, allowing me to learn more about the how, more than endless papers will. It's a MoE and I'm slowly running a human loop, research, build, correct, research.
I’ve been building (launched in Feb) a home phone service for families who want to put off the smartphone for as long as possible, but still give young kids the ability to communicate via landline.

For a long time I wondered how SV startups got such pretty landing pages (here’s a comment I left 2 years back: https://news.ycombinator.com/item?id=37421273). I wanted one for my side projects but couldn’t afford an agency, and the templates online were boring. Creating the page was only half the problem. I also needed somewhere to collect emails for the waitlist.
After AI happened, I built an app (promptfunnels) to scratch my own itch and generate funnels (fancy name for landing pages with a purpose).
Then came the harder part: marketing it. Coming from a tech background, I knew nothing about marketing, so I started reading and came across the $100M Leads book. I realized codifying those principles together with funnels and marketing automation had a real market. My family, friends, and acquaintances became the first customers.
A friend joined me as cofounder and we both quit our jobs to do this full time.
As we talked to other startup founders, they kept describing a tangential problem they called GTM. At the core it was the same thing we were solving: marketing for non-marketers. So we pivoted to RevMozi(https://revmozi.com/), which helps non-marketers do both inbound and outbound GTM.
We’re dogfooding the product and coming out of beta next month.
some of them are non existent today. Check the parent thread - some good recommendations(for 2023) on both functional websites and pretty websites. At that time if I recall linear landing page was all rage, and there were many copycats.
A timelapse platform powered by community photos. The idea is to place a mount and QR code at fixed viewpoints around the neighbourhood. People scan, photograph the view, optionally add their name, and submit. Over time, the platform stitches those shots into a living record of how the place changes with seasons.
Just finished the software side using a boring technology and am about to order the materials for the first few locations. Curious to explore photo alignment once real submissions start coming in. Stitching all slightly different angled photos into a smooth animation seems interesting.
A desktop client for Repomix. Repomix is a CLI which allows you to summarize all the code in a repo in one txt or md file so you can in turn feed it to an AI model for analysis. It absolutely gets the job done it its current state, but it is a personal project so there may be a few rough edges.
It's open source and has no official connection to Repomix. But the developer, yamadashy on Github, knows about it and seemed to like it enough to add it to the Repomix website under the community projects.
I like being able to paste all the code into a browser window and have lengthy discussions with ChatGPT, Gemini and GLM. Doing so in the browser saves tokens over doing it in Cursor or Codex. I like using the Projects feature in ChatGPT in the browser and Notebooks with Gemini because that gives the model context and history on whatever I am working on. It was one part scratching my own itch, one part learning about Python and Customtinker.
It's made specifically for when you just want to get the code and paste it, no muss or fuss. It doesn't have support for flags (yet?) like the CLI because again it is built for speed. Besides, when I want flags, I like using the CLI instead to get granular. Repomix Desktop is for "just give me the code."
I'm a self taught coder so I'm very open to feedback.
Mainly working on https://localhero.ai, automating i18n translations for product teams. Basically runs as a GitHub Action, translating new strings on PRs matching your brand voice and glossary. Got our first fully selfserve customer a few weeks back (found us through the docs). Interesting work lately has been improving how the system learns from manual edits, when someone tweaks a translation in the UI, it feeds back into translation memory and influences future translations in a smart way. Also did stuff like improving our agent skill, so coding agents get glossary/style guide context automatically and they can write source copy that better matches the brand.
Been pushing some new stuff on https://infrabase.ai as well, my AI infrastructure tools directory. Traffic growing steadily from comparison and alternatives pages. Interesting finding is that blog posts rank better but get fewer clicks now because AI Overviews, interactive comparison pages still earn clicks. ChatGPT has also started citing the site more as a source. Adding new content and polishing existing parts of it, added a page focusing on EU based services at https://infrabase.ai/european.
I am working on a task manager that’s way more informative and resource efficient than the windows task manager and works on Linux. It also provides an informative dashboard for docker containers and web servers with proxy support and preference for streaming sockets supporting http and web sockets over the same ports.
I built The Daily Baffle over at https://dailybaffle.com with a whole bunch of word and logic puzzles I designed.
There's Truthsorting, a logic puzzle where you have to order logical statements to make them true or false.
Pathword, a puzzle where you lay out letters along a path to spell out 4 words.
Morphology, a clued word ladder written by a different contribution daily.
And a few others!
I've been trying to promote it for a few months but I haven't had a ton of luck, to be honest. The audience hovers around 500 people and growing it beyond that has been pretty challenging.
My own browser game. I created a browser game engine and building my first ever game with it. I can’t wait to launch it, I think it’s pretty cool. I’ve been working on it for 6 years!
The tech surrounding the game is awesome, the game and engine are fully deterministic, discrete (not float based), and bit-packed data structures throughout, powers of 2 everywhere for really fast operations, and logic and rendering are fully decoupled.
I wrote a simulator for the game and can simulate 10,000+ games in around 50 seconds on my MacBook M1 Pro. Purpose of the simulations is Monte Carlo method to tune my enemy AI (not LLM - conventional bots etc)
I'm building a chrome extension that scans everything you read and highlights text if it maps to a market on kalshi. On hover, a tooltip pops up allowing you to drop money on it.
Use this to doomscroll nba twitter and sports bet, or if you're feeling more highbrow, peruse the NYT and passively gamble on geopolitical events.
As a data-obsessed golfer trying to get to single digits, I need a tracking app that picks up where Arccos leaves off. So I'm building one: https://shortgamewiz.com (still a bit WIP).
After a few rounds of using it, I already know a few things I didn't before: I suck at right-to-left breaking putts, I baby uphill putts too much, and getting out of bunkers consistently is not good enough if I can't sink the occasional save. So I know what to practice now.
Anydrop.org A zero-friction, cross-platform alternative to AirDrop. If your device have a browser, you can drop text or files to it. Doesn't matter if the device is a pc, mac, linux, phones, tablet or smart tv.
There are no installation or login, just load https://anydrop.org on the devices needed. Also support live realtime notepad sync and clipboard for easy share of text snippets. All shares are end to end encrypted.
I'm working on https://www.certkit.io. It started as a solution to handle TLS certificate automation for my other SaaS products, but we realized other people who run on-prem workloads might get something out of it.
It uses Let's Encrypt by default. We use delegated DNS to handle ACME challenge validation (we run the DNS, you just CNAME to us). This means you don't need to give us DNS credentials or anything. And for HA workloads it's great, because there's a central clearinghouse for certificates - so all the machines in your web farm (or whatever) get the same cert, but you don't run in to rate limits with LE.
We're recovering Windows Server guys so we made sure our automation works for painful windows workloads like IIS, Exchange etc. too.
We've had enough interest that we're building it out for real. Just left beta last month.
I've been working on a pure Clojure implementation of WebRTC Data Channels (SCTP over DTLS over UDP). The library provides a minimal, dependency-free (except for Clojure itself) way to establish peer-to-peer data channels on the JVM.
I've always wanted this and have used it to experiment with Gemini's cloud agent Google Jules.
Thanks! I've noticed a big jump when they switched to Gemini 3.1 Pro and it really became useful. I like that I can use it from my phone too. It took a bit of trial and error but I came up with a good ralph loop between GitHub Actions and Google Jules using the Jules API. So basically I have Jules extend its TODO.md with the next set of tasks and open a PR then run a GitHub Action with a few checks, auto-merge, and then call back into Jules to kick off the next cycle if there are still open tasks. It then mostly just runs and occasionally gets hang up on some questions that I then answer on my phone mostly just telling it to make a judgement call and keep the build green. You can check out the prompt, action, and past PRs for examples ex. Jules prompt is here: https://github.com/alpeware/datachannel-clj/blob/main/prompt...
I've been working on a newish variant of Sudoku called Binku. It combines the traditional Sudoku rules and adds the rules from a game called Binario/Takuzu (with 1-4 as one color and 5-8 as the other color).
It's been well received by the (very kind!) Sudoku/puzzle communities, so I'm working on throwing a nice interface on it that fits the rules a bit better. I've found about five other examples of others doing a variation of this ruleset before in one way or another, and it's been fun trying to see how hard/deep I can get this puzzle to go.
I am working on a research institute for East Africa, https://maiyoinstitute.org/. I want to tackle the dire lack of environmental data, by using 1. low cost hardware 2. Artificial Intelligence 3. Long term horizon. The problem set is huge, but I am focusing on low cost sensors for Air and Water data collection plus bioacoustics for now.
I'm working on turning our statically-typed formula engine -- that we use for Calcapp, our app builder -- into a real hosted solution (as well as a library). I discussed it in July last year (https://news.ycombinator.com/item?id=44702833#44704642) and have been working full-time on the project since the beginning of the year.
I figured "I already have a battle-tested solution, I just need to make it modern and spiffy, build a website for it and see if there's any interest -- in the age of Claude Code, this should be fast work!"
Wrong. Taking an internal library and offering it to others -- complete with documentation and modern tooling -- is an immense project, even with the help of AI agents.
Is there a market for a "formula engine in a box"? I don't know. But I also didn't know whether there would be a market for Calcapp either, and that has supported me working full-time for the past seven years. So I'm willing to take another chance.
I track my learning and schedule repetitions in google sheets. But Google sheets sucks on the phone. So I built a dumb frontend reading off of my (public) google sheet which just has 4 columns for links, title, dates and wait times, plus a formula. Webapp pulls the sheet as csv, renders as color coded lists and a couple charts. Chart shows what's due this week on a 15 week timeline. This is the simplest luddite version I could come up with. I don't have a way to share this with others except sharing the source. Not introducing complexity from auth, storage, managing updates from the app, etc.
Social Maps: a user reviews and ratings service for points-of-interest (e.g. cafes) in OpenStreetMap.
I’ve been trying to reduce and eliminate my reliance of the Big Tech and the lack of user reviews and ratings was always a big pain point for me each time I tried to switch away from Google Maps.
I’ve started building a service where users can write reviews and rate “places” (POIs) in OpenStreetMap database, such as a cafe, a museum, or a shop. It’s a quite straightforward CRUD app with bunch of OpenStreetMap-specific features such as logging in with OpenStreetMap and querying places by their OpenStreetMap metadata.
It’s still in active development but it has good docs, a great API reference (including an OpenAPI spec), a demo app with the entire planet imported and queryable, and an early stage Android SDK.
I made https://poemd.dev/ as an online markdown scratchpad that supports GitHub Flavoured Markdown and stores all data in the URL. This means there are no accounts to work with and everything is basically stored in bookmarks if you choose to.
The persistence model makes documents somewhat sharable, but I do find Open Graph previews to be mixed. In Messenger it renders the whole URL, which is quite long due to encoding, and that kills the conversation view.
A non-profit to deconcentrate power over AI through better infrastructure for external auditing/oversight, and better infrastructure for local/federated inference/training https://openmined.org/
Been working on https://searchcode.com/ again which I bought back, albeit as code search tool for LLMs. It solves the “should I use this library” by allowing the LLM to inspect search and analyse it before integration. Can use it to compare multiple repositories before downloading. It comes with a large amount of token savings and can be really useful when wanting to learn about a codebase.
I’ve been working on an OSS backend-in-a-box called [aepbase](https://aepbase.io/).
For the past few years, a group of us from Google, Microsoft, GM, IBM, Roblox, Rubrik + more have been working on a design standard for APIs called [AEP](https://www.aep.dev). The goal is twofold: learn from our companies mistakes around APIs and enable better tooling with less configuration.
We’re at a point where AEP-compliant APIs get a resource-oriented CLI, MCP server, full UI, and Terraform provider for near-zero configuration.
Aepbase has been my way to tie the whole ecosystem together. You run a single binary and define the schema for a resource with one API call. Now, you’ve got a full set of CRUD APIs and support for CLI/TF/MCP/UI. After one API call.
It’s a really cool way to tie together all of the work AEP has been doing.
Love to hear HN’s opinions on all of this. We’re still trying to figure out the best way to sell people on AEP.
Given a distance, an allowable time to reach that distance, a payload to send, and an expected exhaust velocity, how would you calculate the time required to convert energy into antimatter fuel and how much antimatter needed to arrive at the destination (starting from the Moon)?
There are a few side calculations, such as the size of the radiator, estimated footprint of the fusion reactor itself, and how much metamaterial is needed. This is to help figure out timelines for a sci-fi novel, so ballpark answers are completely fine.
The calculations yield what appear to be values around the correct order of magnitude. Would be delighted to have insights, comments, and corrections.
I recently switched to developing VST audio plugins and I'm loving it. Already done 3 [0][1][2] and I want to keep doing this if I manage to generate some income from it. I develop them in Typescript and then convert them to C++ with Webview, this way I have a web demo of the plugin that is almost identical to the one you get for the DAW.
I've got a taskboard that auto-completes easy tasks, specs out and visualises hard ones.
Draws from a bunch of sources, MCP-connects to my agents, comes with a browser plugin to invite meeting bots to calls, lets me (and my testers) leave notes on websites which also gets added in.
The goal is to make work as simple as dragging tickets around, and load as many best practices + review clarity into it
I've set a deadline to finally launch tomorrow, but frankly - I don't know how it's gonna go. Feeling proud, yet a bit anxious about it.
A high-throughput multicast Bitcoin transaction distribution system, with a roadmap towards billions of transactions per second.
Features:
- Control channel for block header announcements, operational mechanisms, and network topology automation
- Separate channels for subtree, subtree grouping, and transaction load
- Transaction load sharding by deterministic multicast group membership based on TXID
- Transaction specialization filtering and retransmission both unicast and multicast, to connect edge networks only interested in a portion of the transaction load for whatever reason
- NACK-based retransmission of missed packets via hash chain gap sequence tracking (per sender, per shard) with automated caching endpoint beacon discovery and tiered network distribution
- BGP-AnyCast based transaction ingress
Basically all the topology pieces to scale the actual small-world network for Bitcoin miners or transaction processors; dense at the core, with layered and sharded group distribution towards users at the edges. Right now just site or org-scope multicast in planned, but provisions are being made to extend via MP-BGP eventually.
For BSV Blockchain but could work for the other Bitcoin variants too, if they ever wanted to scale.
Paste Redactor. It redacts Personable Identifiable Information (PII) from your clipboard when you copy and paste text. It uses a custom trained local AI model so that your PII never leaves your device. That is what it does now. Currently working on it to make it work for agents as a privacy protection layer. The idea being that the most powerful AI models live in the cloud but need access to your local files to be useful. We instead want everything to go though a local protection layer before it is sent to the cloud possibly with labels and then reconstructed locally when the cloud sends back its results. Kind of like a Adblocker but for agents and private data instead.
I'm working on a little local first review tool called Review (though I sometimes refer to it as differ since that's it's original name) - you can see screenshots here https://x.com/rhyslikepb/status/2053149881104265599?s=20
The idea was borne out of wanting to use the review tools that you get on existing sites like GitHub, without having to push and start bloating PR lists. You'll be able to leave yourself comments and code suggestions after review, which you can then pull out in a Markdown file to feed back to your coding agent (or anything else for that matter).
I'm also trying to include some optional (very optional) AI extras where you can use your own keys, and then get a tour of what you've changed and a quick overview of the changes.
I am trying to better my understanding of Agentic coding tools and Tool using Agents by building my own, without relying on an Agent that writes said Agent/Harness
I believe writing my own "Toy Harness" is a good way to learn and understand these tools.
We just received the API usage approval from Google, and I'm integrating GBP to https://pinpost.io this week (our reliability first social media management tool)
I am working on a framework that lets you easily create tools inside the Django Admin - https://djangocontrolroom.com
I've published several panels under this banner already (tools for redis, caches, celery, etc.); I am currently working on a base library layer for tools to inherit from and to make it easier to create new tools.
Essentially, the point of all of this is to make it so that you don't need so many external services; Instead, DCR provides self hosted alternatives. This in turn makes it a lot easier to build and productionalize something using Django.
Reception has been decent so far and I estimate several thousand current adopters (Its hard to estimate based on download numbers alone.) For May I will finalize a common design language, further formalize the plugin system and how it works, and likely release a new panel.
Employee benefit plan analytics. Had a huge dataset long ago as a consultant to the industry and finally vibecoded up a decent frontend. All public data but if you know the data there is a bunch of analytics you can do. Just about to launch and do some marketing in a few weeks, so saw this and thought I'd throw it in!
Closing up work on my modular, hobbyist, analog computer. (Finishing up the manual—the hardware is already a wrap).
Something I can finally enjoy: just playing with it. I tediously wired up a pair of pendulum simulations to drive an XY oscilloscope—got a nice Lissajous curve.
But now I want to double it to four pendulums. Each axis (still just X and Y) to be driven by the sum of a pair of pendulums. With them out of phase, the curves appear to sometimes collapse but then suddenly explode again…
(Love to eventually hook it up to an actual plotter.)
We're working on Webhound - budget controlled long-running deep research. You set a budget and Webhound will use that much in compute/LLM tokens to research your prompt, with built in verification cycles and optional added verification budget. Every claim is cited with evidence and a direct link to the tool calls that produced the claim
The goal is to build a deep research product for actual researchers, since we believe that it is an extremely powerful product that is still nascent but has enormous potential - which we've already seen with some early users.
I have fully implemented mutable torrents (BEP 46) in Transmission. When a torrent is created, you can set it to be "mutable", and you (and you alone) can add files to the torrent, remove them, modify them, or change their filenames. Other members of the swarm will be notified of the new change, and begin downloading that as well (if they use a client with mutable torrent support). For leechers, they can choose whether to allow mutability on a per-torrent basis, and only in the fashion that they prefer. They can even store every change (and seed those) too.
I have the macOS, Windows, cli, and web app working with this feature. I had a bit of a mixup with Gtk, so I don't have a Debian package for it, but it's buildable from source.
I would appreciate it if anyone wanted to test it. I'd like to think that the feature would be a big deal, even if my implementation of it's kinda crappy.
Been writing in my blog every day, reading more, created a poker equity calculator, and working on a city wide project where I document attractions, restaurants, and stays I've experienced in my city (very early stages).
Still chugging away at my NES rhythm game. Currently, in addition to climbing the content mountain (so, SO much pixel art and music needs to be made) I'm also slowly learning video editing workflows. I was able to put together a brief gameplay trailer this last week:
Right this second I'm looking for an alternative to After Effects that runs on Linux systems, as kdenlive has some limitations with its layering implementation. I'll probably give Blender and Godot both a whirl, as I want to get more comfortable with those tools for future projects.
Aye, the inspiration is not subtle. Technically it is the latest entry in the "rhythm-based roguelike" genre... which to my knowledge mostly includes CotN and its sequel, Cadence of Hyrule. Both are excellent, and I recommend them highly. Of course I'm unaffiliated, so this is more of a spiritual successor (... demake?) and is its own thing in terms of IP.
It is indeed also on Itch. I'm planning to release both, along with a physical cartridge at some point. It's a real NES game, so a ROM is included. (No DRM, of course. I'm not even sure how you would achieve DRM on a ROM chip.) I test on an Everdrive N8 Pro. It's a big game, so simpler flashcarts tend to not be able to run it.
A no-code platform packaged as an AI tool for building data-driven applications and serving as a data store for AI to tell it interact with your data; https://saasufy.com/ - Tested with Claude Code and pi.
I'm slowly but surely working on a first update to my Android app, Tunemark (https://tunemark.app), which I released a while ago. Tunemark lets you add bookmarks to moments in songs so that it is easy to jump back to them. It is really convenient when practicing dancing or music and you need to constantly reset back to specific parts of songs. Unlike most DJ-type apps that could serve similar use cases, Tunemark works with most music apps, including streaming services.
I have new features such as sharing bookmarks and possibly BPM detection planned but also some quality of life changes like better UI scalability for different size screens/split screen use.
Working on a bread recipe community where you can share and iterate on bread recipes.
It's out of personal interest to be able to record my bread recipes and thought it might be interesting for others too.
However, I worked on it for the past ~5 years on and off (well, mostly off) and rewrote it too many times. Now finally close to releasing, bought a domain and setting up all the last remaining things.
I've been working on Mesaphore, an Excel-like spreadsheet app[0] backed by a Parquet-based file format. The premise is when Excel starts off as the starting point, then over time becomes a data exchange format between systems, and eventually becomes a bottleneck for the system. You still want to provide your users something Excel-like but also want to address the limits of Excel[1].
Majority of code (almost 70%) is generated by Gemini Pro and is extremely ugly. Due to a recent eye injury, I've not been able to code as much as I want, so I'm delegating many things to Gemini. Eventually, as my health improves, I plan to rewrite the entire thing.
1) “AI harness plugin build system” to help improve reliability of and increase compatibility across the fragmented AI coding harness plugin ecosystem.
2) Claude code plugin based on some ideas found in https://www.anthropic.com/research/emotion-concepts-function
The main idea is to add hooks that inject “baselines” under some conditions to counteract certain “emotions” that can cause subtle misaligned behavior in agents
3) Final Fantasy XI custom client remaster in Bevy/Rust alongside an MCP integration that aims to allow agents to play autonomously on private servers à la “Claude plays Pokemon”
Been working on and off on a Spotify recommendation egnine after getting tired of Spotify’s repetitive recommendations.
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, curated by you version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.
It works best if you follow a good amount of artists. Optionally you can get recommendations from artists that belong to playlists you follow or you've created. If you don't follow much or any artists, then you should enable that in order for the service to be useful, as right now that's the only pools of artists the recommendations are based on.
an agentic coding scaffold/framework you can reference when building out your next random raspi project. prefer to build around systemd units first; make an idempotent installer script, then put as little as possible custom coding around that.
`impl muster` comes down to: /build out this tool wiring together `patterns` like: C3.dropfolder-trigger; R2.device-binding; C4.lazy-resource-gate
or composite patterns like:
T2R4.device-triggered-conveyor
"Bind a physical device event to a bounded ingest job that waits for hot-storage capacity, proves cold-storage capability, stages local work, and hands output to a hot/cold conveyor."
I need to back up a couple hundred DVDs, so with muster I get out:
dvd-ingester
T2R4.device-triggered-conveyor
Architecture
DVD media becomes ready
-> udev rule adds SYSTEMD_WANTS=dvd-rip@%k.service
-> systemd runs /opt/dvd-ingester/current/bin/dvd-rip-one /dev/%I --apply
-> dvd-rip-one proves DEST_DIR and waits for HOT_DIR capacity
-> completed rip moves to HOT_DIR/<run-id>
-> dvd-publish-one.timer drains HOT_DIR to DEST_DIR
-> publish writes DEST_DIR/.incoming-<run-id> and atomically renames final output
Pipelined; ejects after rip completed. Monitors local disk capacity, retries after NAS comes back online; resumes after random reboot; etc.
I am building Akariq which provides data eSIM data plans to 185+ countries and regions across the world. I am 2-3x cheaper than big brands in the same space. I also prefer local data routing i.e. I don't route traffic from US or EU to Hong Kong, they stay in your country / region.
Just curious, I have no idea how eSIM reselling business works: How can you offer 2-3x cheaper prices? Is it because others have very high margins, or because you have a secret optimisation method?
Great question. Cheaper prices come from a mix of focus on customer value primarily. That includes making sure that the eSIM is high quality (low latency, data routing in the region) and also focusing on getting the best eSIM plan to the customer - transparency, better FUP etc. So there's an element of optimisation involved here.
I'm working on JRECC, a Java remotely executing caching compiler.
It's designed to integrate with Maven projects, to bring in the benefits of tools like Gradle and Bazel, where local and remote builds and tests share the same cache, and builds and tests are distributed over many machines. Cache hits greatly speed up large project builds, while also making it more reliable, since you're not potentially getting flaky test failures in your otherwise identical builds.
I have been working for some time on a budget body/facial mocap solution with Unity. Mocap is hard, and what exists is locked behind subscriptions or is just very expensive.
With Unity I'm trying to bundle a bunch of different free, cheap or open source solutions together. For facial, that includes a custom converter from the output of Deadface (based on Mediapipe) with ARKit blendshapes, and also eye movement. For body it's a custom hook to SlimeVR that allows you to mocap with cheap-ish IMU-based DIY trackers, and all that on top of a custom made (not free but open source) physics rig solution that gives you accurate rigid body real time collision, saving on cleanup work.
It's being going really nice despite being an unusual workflow. Hope to release it as a plugin for a in-development sandbox game in the near future. Mocap and animation has been my passion long before i started with tech stuff, and finally I'm able to pursue it.
I'm working on an Arabic-language Electronic Health Records system (moving to Syria in about 2 months and planning to market to clinics there). No current plans to release as Free/Open-Source, but the stack is Elixir/Ash/Phoenix/LiveView/Bootstrap.
While working on it, I realized I should build a small Hex package for authoring and playing demos right in a Phoenix app (it's very easy to author scripts with AI or by hand):
Incremental Markdown parser that emits streams of semantic events, plus tools to manipulate them - designed for real-time rendering of streamed LLM output.
My wife and I continue to work on Uruky, a simpler and cheaper Kagi alternative, based in the EU [1].
Since last month we’ve stabilized the search UI/UX and have 5 search providers you can choose from and sort as you prefer.
We entered May with over 50 paying customers and have recently launched Uruky Site Search [2] (for website owners, this effectively is our own search index and crawler, which we’ll be bringing into Uruky soon as another search provider option)!
Customers really enjoy the simple UI (search doesn’t require JavaScript) and search personalization (from choosing the providers to the domain boosting and exclusion). We also have hashbangs (like "!g", "!d", or “!e”) when something doesn’t quite give you what you’d expect, though.
You can see the main differences between Kagi, DuckDuckGo, Ecosia, etc. and Uruky in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you get a copy of the source code!
Our main challenge right now is outreach because we want to do it ethically, and it’s hard to find communities or places to sponsor which are privacy-focused and don’t require €5k+ deals. Ideas are welcome! We’ve been sponsoring a project per month (Qubes OS, The Tor Project, and Hister so far), with our limited budget of ~$100 / month.
Because of bots and abuse there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a week for free, reach out with your account number and we’ll set that up!
Hey, I'm from the EU and love to see such a project!
One thing I can recommend right off the bat is Reddit - there's many privacy focused subreddits, and also you can share the whole project in EU related subreddits and e.g. r/SideProject.
Would love to try it for a week, this is my account number - 9772263817629091
Working on a tool that lets you author in WordPress as usual (own Docker container, full editor + plugins) but exports the site to static HTML for the public version, so PHP doesn't run in front of readers. Deploy targets are Cloudflare Pages, a Git remote, or statichost.eu. Solo, just launched, currently grinding through hardening. Called Stelae if you want to have a look.
Since I started it a couple of months ago, it's been used by me to transpile SQLite to Go, and by some other folks to transpile other C, C++, Zig and even Perl libraries to Go.
Read your most recent piece and I like it. Beat generation sort of feel, extemporaneous, haunting in a good way. Keep writing even if only a handful of people read it.
It's been three months now of building Crit - https://crit.md - local first, open source tool for reviewing markdown and code output from your favourite AI agent.
It's inspired by GitHub PR review workflow, only with quick iterations and local.
It's been great! I found some dedicated users, dogfooding it every day with Claude and starting to get more contributions from the little community. We just got accepted into Homebrew core which was my target.
I'm expanding the team features now as I've got a few users keen to get the sharing service deployed in their private networks!
An EU replacement for PagerDuty, focusing on the absolute basics - SSO as the minimum even on free, no AI driven workflows, overviews etc. but may include ML/AI driven insights in future since that’s the way the world seems to be going.
fDeploy is a self-hosted Windows deployment automation tool — a lightweight, on-prem alternative to Octopus Deploy. It consists of a Server (Windows service with a Web UI) that orchestrates releases, and Agents installed on target windows machines that execute deployment steps (IIS sites, file copies, scripts, etc.) across environments.
Just started working on a book to celebrate the 50th year of our symposium, which is coming up in 5 years. The initial idea is a how-to book, filled with essays from past contributors, but since we only started yesterday - that may change.
I've been going through Nora Sandler's Writing a C Compiler book and writing a compiler in Python. I'm excited to start the chapters on optimization - those seem like the most fun algorithm problems.
I recommend the book. It certainly isn't easy (maybe 3x harder than Crafting Interpreters), but I've learned a ton (eg how to deal with operations on different sizes of types, or the trick of using pseudoregisters to avoid having to figure out registers up front).
I vibe-produced a website for an (earnest?) pastiche of Final Fantasy games (i.e., for a game that does not, and probably never will, exist). I noticed that Nano Banana could generate reasonable facsimiles of Square Enix's promotional render style and ran with it. Next up: faking some gameplay or a few shots from an FMV-style cutscene.
I’m working on a ground-up implementation of RADIUS with everything running on stateless compute. It’s a beast with many problems to solve but I have EAP-TLS, TTLS and PEAP all working. I’d love to connect with folks interested in this kind of thing.
I was responsible for multiple RADIUS services used by millions of people every day. The existing software is slow to build with, difficult to scale and expensive. I couldn't let it go.
Step one was building the platform to run it on and make it sustainable as a business. Step two is implementing protocols like RADIUS that lack a separated compute/storage model but should really have one.
I chose C# because I know it, and build native single-file executables using AoT.
Sort of uncurious about your implementation, but very curious regarding your trauma. I have found a lot of the OSS options for RADIUS suck in specific ways. Never had to scale it however.
The two are linked. Need to change the configuration of a fleet? That's going to be restarting every instance of the process. Update an extension model? Same. Load balance? You'll need one that understand RADIUS or clients will suffer because of incorrect session affinity. Client with dramatically different loads? Better put them on different clusters. Somebody had a power outage? Better have 10x capacity on hot standby for the load.
And on and on.
A stateless compute model with separation between the packet handling and the authentication logic solves pretty-much all of it.
A small, generic Go library for retrying fallible operations with exponential backoff and pluggable jitter strategies.
https://github.com/nodivbyzero/try
Working on Marmot https://github.com/maxpert/marmot recently added support for vector index. My local benchmarks show pretty decent QPS with less than GB of RSS on DBpedia dataset.
Interesting part is that I started off implementing a research paper for indexing and performance was not good enough. I ended up tuning things up for my own use-case and ended up with good enough replicatable RAG store.
Main project is a deterministic .NET runtime (https://github.com/Smaug123/WoofWare.PawPrint). Today I upgraded it to net10, which has naturally caused dozens of regressions which Claude is beavering away at.
Side project is my own agent harness, https://github.com/Smaug123/writ , which is being built sandbox-first and with Nix as a first-class citizen. Obviously everyone has to write their own agent harness as a rite of passage.
I'm working on Isola (https://github.com/isola-run/isola), a passion project of mine. It allows you to easily create and control sandboxes for executing untrusted code on any Kubernetes cluster (one helm install). To support some features I wanted (like on demand snapshotting of specific containers' filesystem in a sandbox pod or limiting egress rate from the sandbox I am working on now) I contributed some changes to gVisor. Happy to chat about the design and implementation of such a project if anyone interested!
I'm working on Repple (https://repple.sh)! It's a modern spaced repetition x incremental reading/PDF library app with a few (tasteful!) QOL AI features.
I've been using Anki for 10+ years and love it but always wanted something with a cleaner UX and a reader view. The recent Anki ownership change pushed me to finally make something, and it's seeing some traction :)
Right now I'm focusing on getting the reading and note-taking view to be nice. I used to use Polar Bookshelf (RIP) but that went away, trying to make something better.
Currently working on `imgsrv` which is basically a container registry but it holds disk images. Enforces versioning, allows attaching multiple formats for a single release, prioritizes immutability, etc. Intended to build fully automated image release pipelines. I use a PXE setup for my homelab, so having a common place to manage image release lifecycle is helpful.
Right now I intend to make it compatible with Incus as a remote. So it's just a matter of adding it as remote and then you can consume all of your versioned images.
I'm making a surf forecasting site a la surfline.com, I started mostly to have an API to use for my tidbyt, but I figured I might as well make it a full thing and built my own features! It's on quickswell.com but it's only Socal at this time (fewer spots to compute)
I’m building a small map application that allows me/friends/family to explore data overlays about morel mushrooms phenology and habitat (ground temp/moisture/terrain/aspect/tree species/etc) in our area. There’s some lightweight forecasting and timing models to help guess at near-term fruiting. I had a big push about a mouth ago to tighten things up, and initial experiences in the field this year have been very promising.
I’ll keep chipping away at it this year, and probably expand beyond morels to other seasonal natural phenomena that my people enjoy like smelt/salmon run, wildflower blooms, etc.
Writing my own programming language eyg.run that for a long time had no syntax. I worked on a structural editor for a long time and this weekend I finally documented the sneaky text syntax that did exist for testing.
So the structural editor I'm not sure about the future. The language is still fun to write and use tho.
I'm working on https://vtxmacro.com, a free and fully autonomous LLM trading platform. Basically have any model you want trade for you. Right now I support ~860 models across 16 providers (including OpenRouter), plus Local AI and OpenAI Compatible endpoints.
The bot settings (system prompt and user prompt, temperature, reasoning, etc.) are 100% transparent and customizable, and all users can view and copy anyone else's settings from the leaderboard. The goal is to build the best trading bots possible by seeing what works.
You can run a bot on Gemini 4 31B with a free tier Google AI Studio account (I'm running 5 bots on it myself). Or just run Gemma 4 26B on your PC if you have the GPU for it. I'm running 5 on my 5090, so I'm trading with 10 bots total.
The platform is connected to Hyperliquid and you can trace all the trades on the blockchain from the user's Analytics page (always public).
The way it works is you set a loop interval (default 1 minute) and the model receives the candles, market stats, indicators, account balance, current positions and so on and decides Buy, Sell, or Hold and how many units.
It's still experimental but I have already processed 1m+ prompts, 10k+ trades, and almost $1m in volume since January 2026. I have around 15 bots running right now, you can check their PnL on the leaderboard (public). I've made a lot of changes in the last few weeks so most recent either 24h or 7d results are the most relevant. The model you use is super important (Gemma 4 31B so far is the best value I found, better than Gemini 3 Flash and you can run it for free) and also the coin you choose is important too. Preferably, you want something that's trending. My friend's bot did well with ZEC and VVV this week.
Right now I'm working on improving reliability (I bought a Japanese VPS to run my own HL node), and this weekend I moved the app from Render to my own DC VPS for 10x+ cheaper and 1000x more bandwidth (25 TB instead of 25 GB, seriously if you're using Render and want cheaper infra look into buying your own VPS).
I'm also implementing CLI/MCP for OpenClaw support. And next is an automatic screener that will use LLMs to pick the most promising cryptos to trade (since I noticed this has a huge effect on PnL).
If you have questions, let me know, the Trade page has my Telegram group link.
I’m working on Beanback, my side project SaaS app for ‘effortless digital loyalty for cafes’.
It replaces paper stamp cards with Apple Wallet passes (Google Wallet coming soon) without the need for customers to download an app or signup. It’s still very work-in-progress (forgive the landing page) but I’m enjoying using Ruby on Rails. Please let me know your thoughts!
Still working on ghidra-delinker-extension, trying to wrap up the OMF object file exporter at the moment. Then I'd like to implement generation of debugging symbols (at least DWARF and CodeView, maybe STABS and CTF), although lately I've received a PR for PowerPC and an issue for delinking shared objects.
I'm also thinking about writing the Necronomicon of delinking at some point. The extension keeps spreading by word of mouth and there's only so much UX improvements I can do, for something that requires throwing everything you've learned in CS 101 into the trashcan before you can "get" it.
For occasions like birthdays or Christmas where people want to give you gifts, I have always wanted to ask them to make donations to charities of my choosing instead. So I built an app to enable this: http://donateyourgift.com/ It is very simple but I didn't find anything quite singly-focused like it, so I built it just to scratch my own itch.
I have been experimenting on using AI for hardware development. I showed some experiments on HN a couple of weeks ago (https://news.ycombinator.com/item?id=47801255). I am now trying to make my approach a little bit more comprehensive and structured, instead of several disjoint MCP servers, a single platform that connects lab instruments to AI assistants: https://teasel.tools/
As a demo, I repaired an old Philips PM5190 function generator (about 40 years old) and connected it to Claude Code. Lots of fun. Going to post a follow up video the next couple of days.
The other day I got into some pretty weird territory with Claude, trying to map out what an immortal ASCII cat would look like. Basically an autonomous Tamagotchi.
The idea was to create a quine that runs forever on something like Akash network with its own crypto treasury to support and pay it's bills and try to replicate. It would then talk to an LLM for support and actions on what to do to stay alive.
It got pretty out there. Stored some of the ideas here.
I’m working on a tiny terminal config / dotfiles / tool installation manager so I can keep everything in sync between my machines. Also includes profiles so I can tailor each machine how I see fit. https://github.com/phalt/pauldot
Building tenuo.ai (https://github.com/tenuo-ai/tenuo): task-scoped authorization for AI agents. Rust implementation of capabilities + cryptographic offline verification.
I am working on mesh (https://growmesh.io)
I started working on the topic of human development two years ago and I dived into the topic of how humans have been trained, manipulated, educated or brainwashed.
My central idea which I am investigating is that whenever a person is interacting a highly tuneable ML model such as the X/Fb/TikTok feed or chat interfaces with LLMS, does the thinking and development of the human happens more times or less due to the new experience.
After having it on my TODO list for a long time, I've installed EndeavourOS on another m.2 drive on my desktop. With the advancements in gaming support on Linux over the last few years, over 80% of my daily tasks, work, and games are well-supported by Linux. I've been using Linux in VirtualBox or WSL for many years, but it's been a long time since I've ran Linux directly on hardware. I'm excited!
I've been working on a AI app to replace Claude Desktop and Mobile for personal use.
The main goals are to own my data (memories, artifacts, chats), be able to switch AI providers at any point (if one is down or I want to try a new model), have the same experience between desktop and mobile especially when it comes to working remotely on code.
A bigger vision is to offer everyone a alternative to Claude and ChatGPT they can own just like OpenClaw but with a great app experience.
I hope to have the first beta published by the end of next week.
An LLM benchmark for open-weight models only, with secret questions.
The questions are asked multiple times to calculate a consistency score.
The results are available in JSON, containing the hash of the question with the number of correct and incorrect answers, the number of unique answers, and the number of times no answer is given. (Uses \boxed{})
A civilization clone, but going way deeper than is reasonable (inspired by dwarf fortress). I'm currently building the geophysics simulation that will allow for realistic terrain generation, powered by actual mantle convection and plate tectonics. Once this is finished, then an actual per-cell atmospheric and oceanic model. This should keep me entertained for at least a year, at which point I can start working on the actual gameplay part of things.
I’m working on bomberman in ClojureScript, using no libraries, and making sure I write every line myself, it feels good to go slowly for a change having used a lot of LLMs in the past year.
I’m working on what I call a Software Delegate [0].
You delegate a task or GitHub issue to it and it uses AI coding agents and developer tools to write the code, run checks, read failures, fix problems, and iterate until the result is good, then comes back with a pull request. It does everything a human dev would do, fully automated.
I’m working on Recoil, memory safe, compiled static language (yeah, I know, everybody’s doing it) with Rebol syntax and built-in candies like parsing, finite state machine and rich syntax (that’s given, because of Rebol).
It’s nice to see how well-thought language design can pay off years later, with lower token usage. From entropy POV, Rebol syntax is certainly close to optimal state.
Please comsider adding log-scales to be able to compare related but wastly different in popularity topics. Also would be nice to show one topic versus another to see a correlation.
Currently developing https://pelicantools.app, a collection of tools to rework YouTube. Any YouTube video can be transcribed to an elegant text or a complete article.
If you're a creator, researcher or developer looking to reap the rewards of a video without consuming it fully, then it's helpful.
Whole thing is up and running on vercel.
It's a work in progress — would be great to get some input!
Better GitHub insights: https://temporiohq.com - still new and there’s a lot of question about how to adapt to the age of accelerated software engineering.
I can't really go into details of what I am working on. But I'd like to say that a lot of European corporations are running their stuff on Azure and are very much interested in having Data Lake(house) platforms tailor made to their business and IT requirements based on Databricks and their stack. I mention this because I find this mismatch of what I see being relevant in business and what is being upvoted on Hackernews quite interesting (for the lack of a better word).
Working on an RSS reader (https://github.com/megaflorasoftware/serial), trying to see if there’s room for a FOSS RSS reader that’s a bit more fun and less brutalist than the other great but more technical user-minded options out there
I'm improving my web app to learn languages with short stories: https://webbu.app. I've been making it easier to track your progress, hear pronunciation of words, and adding more advanced levels.
I think stories are a good approach, although there's something grating about the voice / monotony after 1-2 stories. Have you thought about narrating yourself?
For example, if I downgrade from Max to Pro I'd still be able to use the subscription, but also run sessions with other models (less expensive/local) as desired:
ccode init-config # initializes a new config file for me to set everything up
ccode edit-config # opens it in my editor so I can change, can also include editor as argument e.g. vim
ccode # launches whatever my default profile is
ccode --deepseek # Using their API key, they have a discount this month
ccode --openrouter # Whatever OpenRouter model I have configured in the config file
ccode --openrouter-preset # Also supports OpenRouter presets e.g. if I don't want to use quantized models
ccode --deepseek --control # launches a Remote Control session, shows up in web/desktop app as a regular session
ccode --deepseek --auto # overrides the default permissions, --yolo also works
... (and so on, there's more examples on the website)
Source available, pre-built binaries on itch.io, pay-what-you-want with a minimum price of 0 USD, probably get it for free first if interested in taking a look.
Also thinking that I might make it an Anthropic API --> OpenAI API proxy that allows talking to providers that don't support the Anthropic API directly, alongside allowing switching models dynamically during a session (Claude Code wouldn't even have to know about it, it'd just send requests to a local endpoint and the proxy would do the rest).
Early on, but Go is lovely to work with, mdBook is great for getting a site off the ground and I'm really surprised that more people don't use Itch.io for distributing software (or the pay-what-you-want model in general), it's dead simple!
Trying to get my product (desktop application) to the state of minimal sellable version (according to my quality level expectations). I tend to be perfectionist, thinking it is never even good enough. Hopefully I can show it to you/world in the summer, and hear what people think of it. But for now (or the past 5 years), I have nothing to show and tell.
A language learning app called lexaway. Premise is people can learn like LLMs learned - word prediction. I use tatoeba, an online sentence pairing thing, and it's nice well it's worked for me. I hate the green bird fyi so it's free and open source.
I'm working on GPS tools to help support my current contract. I've found there are no good tools for tracing a route on a map and having a mobile device think it's traveling that route. I'm not just talking GPS coordinates, but speed, direction, motion detection, precise timing between waypoints, being able to play these trips forward and backward, step by step, etc. I'm talking time-travel debugging for GPS applications.
I started a new software defined automation project. I wanted something that I could just open a webpage and start writing code that could just be uploaded and ran instantly. I picked an ESP32-P4 for the first hardware. It’s MIT licensed and has a git repo that I put up this morning https://github.com/OpenPiLab/pilab-esp32-p4-plc
A scripting language that is very fun to write and lets you make interactive music, installations, generative compositions etc https://github.com/audion-lang/audion
Working on https://mdview.io - markdown reader for big documents, including navigatable mermaid diagrams, LaTeX, Fixing broken syntax and ton of other features. It's early stage but getting popular really fast( I guess it just does it's job right)
Working on new puzzles for my tiny word puzzle web game for programmers and computer science nerds.
It's a PWA and works offline. Tech: js, no libs, Canvas API, Web Audio, not vibe coded, but I did use Claude for graphics and tests. Puzzles curated by hand.
I'm working on Tidepools, a daily journaling / task management app (local-first, Mac/iOS/web) with a proactive AI coach. Mostly what the coach does is ask you questions. It can also suggest tasks. Right now I'm working on sandboxed plugins that the coach can modify, so the user can request behavior changes.
I've found it hard to keep up with movie and TV news (particularly when the new Backrooms film is coming out).
So, I built an agent to help remind me -- it's a subscription based service that sends you updates every morning, and stores your preferences so it can learn what you like.
I'm learning about inference by running vLLM on a k8s cluster (EKS), building a gateway to keep a <2s TTFT SLO.
Most recent ha-ha moment: I kept wondering if it was normal that my cluster was only able to process 4 requests per second per vLLM engine (just seemed really low to me).
I realized a better metric is in-flight requests... Each engine is processing 70 requests at any given time, streaming tokens for over 30s.
Deeper dives into those uncover interesting limitations that don't seem to be documented anywhere. On the other hand, it is through those reverse shibboleths that I am now able to tell that my boss's boss has no idea what he is talking about llm-wise.
I've been working on a set of custom PHPStan rules that started off as a replication / modernization of rules from PHPMD, but has evolved to include more than that.
https://acoust.io began as a project to learn React. However, I received a few customers after posting it on Reddit. I’m still figuring out the best way to position it in the crowded market, but I’m enjoying the process of building and learning.
A podcast that isn’t about AI (in the normal way)! I started Pagenerd with some friends to talk about science fiction - loosely defined - and give us a chance to hang out. It’s pretty good. Find it at https://pagenerd.com which links to all the usual places.
Dealing with some rough stuff in life so I'm involved in random stuff to distract myself. Moved my personal blog to Astro. I wanted to scratch and itch I had about self hosting my comments. So I built a lightweight node-based opensource comment system called discuss - https://github.com/karthikeyankc/discuss.
I‘m building a way to record and replay AI image and video generation API calls to any provider so that in testing, people can save money. This is part of our AI media model gateway https://lumenfall.ai
I am working on the Learnix operating system (https://gitHub.com/sagi21805/LearnixOS)
Mainly an educational project, to understand and teach about OS and Rust concepts (The OS is written in Rust)
My partner & I have been making this wordle/wheel of fortune inspired daily - https://crosses.io
Each guess can be a single letter or a full word. Revealing letters helps you make word guesses, which are more efficient since it reveals all instances of those letters across the board.
It's been really gratifying seeing friends enjoy the game, now we're trying to figure out how to get in front of more players. Leave us some feedback if you stop by
I've been working a faster GUI for Claude Code //other CLI tools (https://fluidstate.ai) that works in your terminal and can run multi instances in a tab and you can tab between them quickly regardless the tool
Wrote a Forth VM in C in about 1996 based on TCJ articles by Brag Rodriguez. Managed to get it to compile with modern GCC this morning and fix all the horrible issues with valgrind. Trying to adapt it to a context where it'll be usable for a spreadsheet-like system with reasonable decimal numeric precision. Consider it an RPL calculator with an Excel-like front end.
Just rolled out a big new update for my video cloud platform https://www.kollaborate.tv with a new player, side-by-side playback comparison and a big improvement in accessibility.
Currently we’re using AWS and Backblaze B2, but I’m formulating a plan to move to colocated servers. Not being billed per GB will open up a lot of new opportunities. Even at today’s server prices the math still adds up.
I'm building an AI Dashboard & AI Leaderboard where you can see who generates the most lines of code using Codex, Claude, Copilot, Cursor, etc. https://wakatime.com/ai
https://vistacker.com - local first task and note taking TUI and iOS app, disconnected operation, auto sync across multiple machines with optional encryption so the service can’t see your data.
I've been working on Betterleaks for the past three months. It's the successor to Gitleaks since I'm not focused on that project much anymore. I just released v1.2.0 which added GitHub as a source to scan for secrets against and a new filtering system powered by CEL for more expressiveness.
I'm building Lexeme (https://trylexeme.com), a SaaS service that tracks how AI models like ChatGPT cite and describe your product vs. competitors, and tells you what to fix first based on estimated revenue exposure.
From 50 to 5 seconds. The world's fastest and most up to date investment ai. It's powered directly through our database to ground the information and reduce hallucinations. Still in development though.
I’m working on a project that blocks agents from breaking rules. The rules are enforced through hooks and work across Claude Code, Codex, and GitHub Copilot.
Well, all of a sudden, now that I kinda quit my gaming time sink, all my mini projects are finally being completed. All small, but useful, things for my setup that seem to slowly become a part of a bigger personal project. And between that kid and lots of books.
Ngl, it is weird for me now. If this is midlife crisis, I am loving it.
Working on an idiosyncratic tool that lets users use AI to help write statements of work without losing the high bar for accuracy and consistency that these documents require. Right now, it's somewhere between Typst and Gemini in Google Docs, but not as good as either yet.
Working on benchmark arena for AI agents with my wife.
We grab interesting business problems, turn them into fun challenges for hundreds of AI engineers to find the best architecture for. Insights are shared back with the community.
It is a fun learning process with unexpected scaling challenges.
while I was using claude code, I was playing some lofi music in the background while it was 'Combobulating' and I thought what if it could auto-play lofi beats while working and stop when it has finished running. So I built a claude code plugin, I call it vibe-coding. Can check out/add the repo as a marketplace and plugin from here:
https://github.com/Vinayak-Shukla/vibe-coding
https://pockli.com - I've always needed a better workflow for managing the stream of documents people hand me — then expect me to pull out of a hat months or years later, like a magician.
i am working on an offline weights harness for non-technical people, writers mainly. it's designed to work forever but also be adaptable as more weights get released etc.
it enforces very few paradigms, runs in the browser, and allows users to view and edit agent config files within the UI.
it's kind of a nightmare to try to figure out how to do this appropriately, but it's an interesting challenge and i have seen very few (~0?) projects with an approach like this ...
all the offline harnesses are optimized towards coding, vs. general text manipulation aka "writing."
The same thing for 10 years and every couple years it gets reimagined while trying to get to the original goal of building a replacement for Google. It's called Micro.
Trying to make a stab at improving RSS feed discoverability. There's a website portion and an app portion. Hope to have something to show off in a few weeks.
- Built with Tauri — installer is small and start-up is
near-instant on all three OSes.
- No accounts, no telemetry, no MDX server in the loop. Sync goes through
whatever cloud folder you already have (iCloud / Drive / Dropbox / a plain
directory).
- Tab-to-accept ghost-writing is bring-your-own-key
- Exports to PDF, HTML, DOCX. Tables, math, diagrams, code blocks all live
behind toolbar buttons — no syntax to memorise.
good idea, i am thinking about it, but i guess it will be not that rich in formatting like the desktop app, the architecture design here using "vault" is a 'problem' for extend to mobile, maybe a lightweight re-designed version :-)
Retired so two projects; a 2D arcade board using a RP2350, and my 3rd sci-fi/techno-thriller novel: Currently approx 140,000 words into a 100,000 word novel and about 50% complete.
Thank you, I appreciate it. The helix simply renders candlestick data (OHLC) in 3D, with volume encoded in logaritmically scaled candle thickness. There's more info on the about page of the experiment: https://cybernetic.dev/helix/about
Using this app, you may fall asleep in 20 minutes (maybe within 8 to 15 minutes)
Simply start the session and imagine what you hear.
Like if you hear "calm river", imagine that. If you hear "heavy rain over a tree" imagine that. And you may fall asleep soon.
In measuring how long can esp32 stream video over wifi using single 14500 battery (AA size but 3.7V lithium). So far it seems like 2h 8m is the limit. I'm using tps63020 buck-boost to 3.3V.
A few days back, a book on FreeBSD Driver Development was posted here [0], and everyone assumed a) it's LLM slop and b) a terrible introduction to the topics covered.
I scanned a couple of chapters and realised it likely wasn't LLM generated, it just needed an edit. The intro to C is a hard and weird intro, but then driver development in FreeBSD is hard and weird and people who aren't prepared to get through such intros probably aren't going to get through the rest of it.
Being the contrarian, I've started going through it. I was involved on the periphery of the FreeBSD project ~25 years ago, went to conferences, ran a BSDUG in my hometown, and so on. And I realised I've missed systems programming and FreeBSD itself a little, and in recent years became a little sentimental.
What I've discovered so far in the first few chapters:
1. I miss FreeBSD. And it's weird my muscle memory kicks in and am surprised in a lovely way to find familiar things like /etc/rc.conf work the way I remember them.
2. This is not AI slop. There are issues that I can blame on him not using the same platforms I am (if you're on Apple Silicon, just use UTM and the aarch64 ISO - don't use the VirtualBox config he suggests, as an early example), but as somebody who sees a lot of AI generated content in my day job - this isn't it
3. I have got excited about coding again for the first time in a while.
So, this is my hobby for a while. Go back to where I started, get into low-level systems programming again, I have some ideas on some hardware I want to help out on... it's different to a lot of what I've been working on for the last decade or so, but that excites me.
The idea is that each morning, you click the "New Day" button, and your Todo list along with other notes carry forward from the previous day to the new one. When you accomplish something, you add it to the Done section. Other sections can be added as needed. I have been using a text editor and/or shell script for this purpose for about a decade, but have been inspired to make it into an app now that I can delegate the boring bits of app development. It is not quite done yet, but it's getting close to being usable.
(* To the inevitable downvoters, this is in part an experiment to get familiar with what SOTA LLMs can handle. With the intent of comparing it to local LLMs once I get my Strix Halo set up as a coding assistant. I only code as a hobby currently, and have too many other hobbies, and this app wouldn't exist without something else doing the heavy lifting. That said, this is a pretty low-stakes application and I don't commit any code that I haven't reviewed and don't understand.)
A reactive programming language for games! Properties signal when they change and you can register blocks that tell the engine how to use that property, not just once but every time it changes. It’s a more declarative way of making games which I think is lots more productive.
I’ve been working on this for four years, it’s been a big project!
cascade-editor.pages.dev - a free node-based image editor that works with image sequences and has an associated desktop app. It’s pretty incredible what you can do in browser these days with wgpu and wasm- everything is cross compiled from rust.
I got into creating my own rings, and I’d really like to create one with ore I harvest myself. Gold is too hard and silver can be kinda dangerous, but malachite is pretty safe and I can just drive to Copperopolis to pick some up.
Basically: smelt the malachite with flux and charcoal to get pure copper, flow that into an ingot mold, hammer it into shape. Then I’ll have my own ring, with metal I collected with my own hands
On my spare time, I am working on my game, a sci fi dungeon crawler – written in Haskell. Currently finishing up the graphics engine. OpenGL based. 2.5D but with a real 3D dynamic light system. In game objects and entities cast realistic soft shadows, and are lit up realistically. Took a lot of mathing and thinking to get working!
Working on a Platform That hosts Open Source software & Gives users Enterprise-Level AI Assistants & Support to challenge Saas Software (Just a MVP right now!!)
I just hate the Saas Scene today - even a small productivity app is worth $10-$15 / month . When you couple that with a bunch of apps that you use , you spend hundred of dollars in hard-earned Cash .
The Open Source Community is Amazing on Some fronts , but then enterprise & non-technical users can't use them without a layer of Support , Hosting & Setup Assistance .
We want to be the delivery layer between the Current Open-Source Community & Saas users .
Got a lot of ideas to work on it , but decided to build out a small version right now and launch it !!
the requirements for growth keep changing plus all the AI noise means that the playbook changes regularly. staying on top of the state of the market while improving/maintaining the product and understanding our icp + exploring new verticals is a tricky (but fun) task to manage!
I got let go back in March, and since I've pivoted into building a game.
In the 3 weeks leading up to unemployment, I had gotten way more into an old GBA game I used to play back in the day, Harvest Moon Friends of Mineral Town. The (remake of the) game that inspired Eric Barone to make Stardew Valley. I was bumping into the same in-game limitations of the cartridge and platform that always made me want more from it, (and while Stardew Valley was nice, it never fully scratched that itch) and as I found myself unemployed, I found the mental space to start building.
The game is going to be a farming tycoon/city builder game where you can buy farm stands and advertise to sell your goods. As your operation grows, you grow the local economy and people move to the town turning it into a city, opening up the chance to sell at farmer's markets or supermarkets. As the city grows you'll have to buy/sell land with the city and work with the mayor to plan where the city should claim new land for you to purchase so you can stay on the outskirts with healthy soil (or in the endgame, run for mayor and manage the growth of the city yourself, a la Sim City/Cities/Frostpunk)
I chose Love2D as my engine so I can use the relative simplicity of 2d art in 2.5D pseudo-3D instead of 3d modeling. The world space is a 3d euclidian grid of cells wrapped around a horizontal cylinder on the x axis. The view space is perpendicular to the side of the cylinder, giving us a natural horizon at the vertex of the cylinder on screen. The world space coordinates are expressed in terms of the polar coordinates of the cylinder, giving natural rise to radius as altitude, angle theta as latitude, and x axis as longitude. All the world math can be calculated using the trigonometry of the unit circle, and converted to 3d Cartesian coordinates before converting them to screenspace coordinates. I can use regular flat plans and elevations for the texutures of building faces, and render them upon linearly transformed quad polygons. Maybe I can also do some screenspace displacement a al Crimson Desert at the finish line to give buildings window sills and ledges when you see down a side of one.
I am doing the development without LLMS as much as possible so I retain a good grasp on Logic, Language, and Math. I have been having a lot of fun digging back into these multivariable calculus and linear algebra concepts I thought were beyond me (because of some autobiographical amnesia issues I deal with) to discover that no wait, I was taught these concepts in high school and was quite comfortable applying them. All the development is done on my own private, secured git instance on my homelab server and I can pull down the latest revision to my iphone to show off, it's been really cool. Kind of a pita to find a good git app on iPhone that allows custom git servers with ports though.
screenshot of a very early hello world, before I made the mental connection between wrapping a 2d cartesian plane around a cylinder and actual 3d cylindrical polar coordinates, which is why the shapes just sit over the world rather than extending from it, I hadn't yet conceived of the radius of the cylinder being altitude: https://fucci.dev/assets/helloworldspace.png
Too many codes or old or gate kept behind proprietary walls. Many are old and don't use the newest acceleration techniquea to make the simulation fast. Additionally, none of them scale using aws. I want SAS/SAR image to be easy to generate for anyone.
I just started on an open source and open weight supervised learning model to recognize japanese kanji characters drawn on the screen.
I have a working prototype written in Julia which is a very simple neural network. The input is in vector format so traditional convolutional neural networks don’t work out of the box but I swapped the convolution layer with a path simplification algorithm and it worked extremely well. Like 20 samples per character (from a set of only 5 hiragana during prototype phase) was enough to get 100% accuracy in a test collection of 5 samples per character after only 30 iterations of training.
I plan an working with free and open data, which I don‘t think exists for japanese kanji characters (at least not in vector format; KanjiVG only has one sample per character and I need dozens) so I also build a crowdsourcing web site to collect data from random people on the internet.
I am planning to run some more experiments with my prototype model before I release the crowdsourcing web page to an actual server though.
Right now I just germinated a 4x8 bed with flax for fiber. The plan is to grow it for 100 days or so and then harvest, dry, ret, dry, and spin. I need a lot more to do anything serious, but I think it’d be awesome to have a scarf that I made with linen I grew and harvested myself
I'm working on creating the most useful browser start page for power users and workers in tech.
https://newtabwidgets.com.
One of my favourite features is the iframe widget, which allows you to select any element on a website and turn it in to a widget.
This starts from my frustration when opening large CSV files, but later evolved to a log/data analyzer that loads arbitrary format in constant time (O(1)).
https://github.com/Verticalysis/Hitomi
The secret: I engineered an incremental combinatorial parser capable of processing customized format from a steam. Any inputs, including file or the stdout from a command, are first chunked and then fed to the pipeline. The UI is ready when the first small chunk is processed.
Other highlights: 2-mode filter, one with a convenient UI and the other is based on an extensible DSL for complex cases;
Timeline mode scrollbar, a secret weapon for log or time series analysis;
Column widths fit to content automatically;
Native code, no web bloat;
Cross-platform (currently Windows and Linux, MacOS WIP).
If you are tired of all the quirks Excel have when working with CSV files, you'll gonna love it!
* This is my first time actually posting anything on HN.
I've been making a DSL for writing sheet music specifically for drums as raw text, inspired by ABC Notation (but of course just for drums).
Now writing this I noticed that it's kind of complicated to explain and having a landing page would make my life so much easier.
But the gist of it is, you write notation that looks like this: https://gist.github.com/Luigi123/945af7e5cc8dfbfd186f0a99754... and it renders sheet music in PDF, and also allows you to play the same music as a game (DrumMania / DTXMania style).
Now the language / compiler itself has been working quite well and I've been dogfooding it for like six months now. The next thing is an IDE-style editor where you can import a song and write the notation following it. Making THAT has been quite the journey. Here's a screenshot for good measure: https://i.imgur.com/EmlqlrM.png
oo interesting.
is this intended for drummers, or electronic music composers?
It's intended for drummers, but I wouldn't rule out anybody. It can generate sound, and I'm even using some nicer sounding samples I found on the internet, so using it for composition is realistic.
But the main use case I'm going for is my own: making sheet music for drum practice.
On the drummer side of the audience whats the need for plain text vs writing with pencil on paper?
aiming for more extensions to The New Breed than just Syncopation that you could auto-generate for funny practice/things you wouldnt think of to play?
I’m developing X/D Loom (https://xdloom.com), a tool that helps car enthusiasts create automotive wiring diagrams.
About a year ago, I engine-swapped my Nissan D21 hardbody from the Z24 petrol to a TD27T turbo diesel and also installed a whole bunch of accessories, like spotlights, a winch, and an air compressor. But being lazy, I didn’t write down any of the wiring changes I made while doing all of this. So fast forward a year, and now I can’t remember how all the wiring works.
My current project car is a Jeep Cherokee FSJ, and for it, I want to build a completely new loom from the ground up. So to try and avoid making the same mistake I made with the Nissan, I Googled “create automotive wiring diagram”, but all the results were for complex enterprise grade solutions charging $200/month. That’s why I created X/D Loom as a project car guys' tool for creating wiring loom diagrams. It allows you to drag different electrical components onto a canvas, connect them with wires, and export them to a PDF or PNG.
We're working on Drawers (https://drawers.computer), a macOS app to give each of your projects its own dock, space, and windows.
We integrate with macOS spaces to switch out a project-specific dock on each space, containing only the resources you need for that project. We made it possible to add granular resources instead of full apps to the dock (think specific slack channels instead of the whole slack app), to keep the dock hyper focused on what you need.
We built this to stay focused while working on the computer, and we thought that the native interface mixed all our projects together, causing us to get distracted.
Looking for beta testers! Free download from https://drawers.computer
Nice!! been wanting ti build something like this since I got a mac - never did - glad you did.
Does it have project context within apps (like default folders and settings)?
Yep! Each Drawer (project) has its own folder path. We have integrated apps like Figma, WhatsApp, Messages, and Slack to keep them focused on one project.
Would love to hear what you think we should add next!
This looks great, will beta test over the coming weeks.
Thanks! Would love to hear your feedback!! You can email us at hello [at] drawers.computer
Any plans on open sourcing? This is really useful for me but I'm not comfortable giving full access to my mac
This is KDE activities. Install the latest version then you can setup environments based on your activity. Been a feature since (checks notes) 2008.
Is it free for now? This looks like a huge solve to a problem
Looks very interesting, and your page makes the case very well.
I've shared this one before but I built a logistics management system to power deliveries for a business I founded years back and I've continued to refine it since:
https://toanoa.com/
Since the initial MVP, it's done close to 100k orders and I've added new functionality like:
- Intelligent order batching & route optimization that can interleave tasks across orders in such a way that they still have the best chance possible of completion within their delivery windows
- Further refined the mobile tracking logic in our driver app to improve the quality/frequency of position updates while continuing to be as efficient as possible on battery
- Numerous backend/DB optimizations such that average response times are in the tens of ms at the current volumes it's handling.
It's not open source but if you have an interesting use case and are curious about it, feel free to reach out.
With AI IDEs, Personally I had to generate a tons of md files for planning a task, analysis on the code for something or other, a task doc for a feature - a summary to paste into the clickup ... and I saw many devs keeps on generating them, and all tucked away into folders. Good, okay.
For the company I'm currently working I had made a VSCode extension where I can sync the task doc with clickup via frontmatter.
I decided to take it to next level as a side project. I built a CI integrated, git-native, agent template transformable syncing pipeline with git MD files to any project management tools. That means, either you can save your md files vanilla in your wiki (thus using the clickup AI search to dig up later, get insights etc) or you can use a AI agent template transformer to turn it into a task template (Background, acceptance criteria, functional requirements etc.) and update or create a task on a board.
I've been working on it now. I don't know how it will fare, but I feel like product is coming up nice.

I’m continuing to work on my daily puzzle game Tiled Words!
https://tiledwords.com
Forbes just wrote an article about it which was a fun surprise! [1]
It recently turned 6 months old which is wild to me. My wife and I have made a new puzzle every day for half a year! I wrote a blog post about this [2]
I recently released user logins. That went well and a lot of people are using them. I also let you filter the backlog by completed puzzles based on player feedback.
This week I’m going to start releasing player submitted puzzles and release my puzzle building tools. You can watch a video for a sneak peek of those tools. [3]

Thank you for Tiled Words which I play regularly! I introduced it to a couple of friends and now they compete every day for the best time to finish :-)
While you're here if I could make a small suggestion - the wording of the 'type of' questions was confusing to me until I got used to it; 'stop' is not really a type of 'watch' for example, so maybe you could find a different way to phrase those? Maybe there isn't a neater way to encapsulate the idea of 'is a prefix or suffix to', I don't know, but I found it difficult. Anyway kudos to you and your wife, it's a great game!
Hey, that’s awesome, thanks for playing and sharing it!
Great feedback on the “type of” clues. I’ll need to noodle on that and see if there’s a clearer way to express it. Maybe I should just be doing blanks… e.g. for “sun” it could be “___ dress, ___day, or ___ flower”
To me a "stop watch" is a type of watch, that's straight forward. But there are other clues that rely on cultural references I'm not familiar with - and that is, I think, inevitable in this type of game. We all have different backgrounds and there's no universal shared understanding that would make every clue the same difficulty for everyone.
I saw someone on here recently say they like to do the puzzle without looking at the clues, and I've started doing that on and off too, it changes the game in an interesting way.
This is really cool and addictive!
Thanks for checking it out!
If you enjoy it there’s a new puzzle every day and a backlog of over 200 puzzles free to play ;)
I've been playing this since it was first mentioned on HN a few puzzles in. It's a nice idea and pretty well executed.
I have, however, rejected making a user login. I recognise you're putting in time and energy to make something I'm just taking without payment, and it's your right to try to leverage it into something more - I wish you all the best in doing so - but asking for a user login as a gate to a feature you clearly don't need a user login for is enshittification.
I'm implementing Raft consensus from scratch in C++ with raw TCP sockets. Right now I'm working on a high-performance RPC client and server to keep network latency to a minimum. The main purpose of this project is to hone my systems programming skills and get more comfortable with distributed systems as well. One of the coolest things I've learned here is event-driven I/O with epoll and how event-loop architectures work in asynchronous setups.

Being a weightlifter for 20+ years now, I'm working on a barbell speed and path tracking sensor based on newer IMU hardware technologies, which makes it both more precise and cheaper than camera- or actuator-based systems. Ultimately it helps you lift and train safer and better.
It's an intersection of industrial design, hardware, firmware, and software (and some sport science, of course). This intersection is not yet dominated by LLMs so it's a breath of fresh air.
In an early prototype stage as in "strap a Raspberry Pi to a bar", but it looks promising and I'm happy to move forward, also using connections from my previous 12+ years in China.
this sounds awesome. have any videos of it?
Thanks! Working on it, for now it's literally a taped breadboard. :D
Wannabe powerlifter here of about 20 years as well. This sounds like an awesome project! Is bar-path the main metric for safety and "better" lifting? A project I had in mind, once upon a time, was an automatic "Form Check Friday" for myself using a Pi + Webcam.
Not OP but velocity is typically what these devices are used for. Its a great measure of between-set intensity.
Thanks! I think for "canonical" lifts (squat, deadlift, row, to some extent military press) the vertical bar path is mathematically optimal, and for all kinds of lateral or sagittal movements you do more work with weak stabilizing muscles and load joints laterally too. Is it productive work that strengthens your core? Possibly, but it's hard to quantify. It it something that can lead to injury? Absolutely yes.
For more complicated lifts like bench press (J-shaped) or snatch (S-shaped), for example, I would rather set a "golden sample" path with a coach and compare to that.
It's unlikely to be the sole metric, especially given the inverse kinematics of different body types (long/short femur, etc), but together with bar speed, over time, it can provide a lot of good feedback.
It is not "absolutely" something that can lead to injury. Injury itself is difficult to define, and often the reason one experiences pain sensation is multifactorial. Within lifting contexts, generally the factor which has the strongest evidence for injury prediction is how sharply an athlete increases intensity compared to what they have previously adapted to.
No offense, but this post does come across as you only having a surface level understanding of the field. Especially surrounding injury/pain perception, I would be more careful of what you assume is true, there's far more nuance.
As someone who has been very deep down this rabbit hole and hacked together multiple path and velocity trackers over the years (specifically for olympic weightlifting), there is no extra information that tracking bar path will give you that simply looking at the video won't, and often just adds more clutter. You don't need to graph bar path to see that the bar is looping too far forward after hip contact in the snatch.
Velocity on the other hand is a great metric to track and is used as a proxy for RPE. Mike Tuchscherer was the first one to systematize it for powerlifting a while back, if you've been lifting for 20 years you're probably aware of the name.
i'm curious about how effective path tracking can be in comparison with computer vision based inverse kinematics of the body itself. do all forms of bad form have detectable imu signatures?
i wonder if it would make sense to consider it as a data problem, capture a bunch of high fidelity inverse kinematics data for various forms of bad form/dangerous lifting along with the imu data and then work from there. there could be some interesting and unexpected features that are easier to detect than straying from straight line paths with some tolerance.
Side note: My LG Watch Sport smartwatch was able to determine what weight training workout I was performing and somehow figured the weight with astonishing accuracy.
Have you seen https://fort.cx?
I'm building https://vcad.io, a free CAD application with an open source kernel (Rust/WASM)!
I’m an application developer by day, but lately Claude Code and Codex have finally made microcontrollers approachable enough for me to start tinkering with them on the side. I built this little “holographic” display that shows the surf forecast for any beach. While my friend built the casing, and mechanical part of it
https://x.com/paulnovacovici/status/2041722840190480581?s=46...
any details on the display itself?
Display is part of a dev kit EPS32-s3, and the holographic part is an illusion called “peppers ghost”
Beautiful piece of kit. I have no idea how it works from looking at it, fantastic. Please do post a full writeup on it.
Its a pretty straight forward technique, the display is at the bottom and in the glass cube there is a mirror at 45 degree angle facing you (you can see the mirrors edge on the side wall) which reflects the image from the display at the bottom making it look like a hologram
You can create the same effect on a smart phone screen with a video like this: https://m.youtube.com/watch?v=CIszi2Kv_lk and a some clear plastic sheet put together like this: https://www.twowaymirrors.com/wp-content/uploads/2019/11/pep...
OP: beautiful work with your surf projector!
I've just published my first book. The central argument is simple: software development is a design activity, not a construction activity — and confusing the two is the root cause of most project failures. Written for developers, managers, and anyone who has ever wondered why building software is so much harder than it looks.
It's on Amazon in both Kindle and paperback formats.
https://www.amazon.com.au/Code-Design-software-projects-deve...
A way to track versions of ALL software and notify users about new version.
Started with a niche and launched it: VersionAlert for Unity (https://versionalert.com/unity)
Working on the bigger product still. Existing solutions I've found in this space seemed lacking. On my website, I want people to quickly find the software they want to be kept up to date about (with a smart search bar that does the heavy lifting for them) and easily sign up for notifications for new versions. Hope to make a Show HN for it soon!
I finally managed to finish a project and publish my first game on Steam: https://store.steampowered.com/app/4195030/balls/
It's a short chain-reaction game in which you explode balls bouncing in the screen, and need to build up to target scores. You build bigger and bigger combos as the game progresses.
It was a blast to work on it, starting with a small toy and just adding features that "felt right" until I had a game that was fun to play. It was quite hard to find a balance though, so a lot of numbers are arbitrary - but I enjoy seeing people breaking the game in new ways and finding new builds.
These days I've been working on patching reported bugs and sharing the game with people. Now after the latest patch, I feel like I'm done, but I feel like going back at it and adding an idle mode. And maybe simplify the codebase so I can test and iterate better, and then add many more ball types...
I know that any good LLM could replicate this pretty quickly, but I made this myself and I'm still feeling proud of the accomplishment :)
I've been working on RVW, my adaptation of the standard transformer model that is capable of online continual learning without catastrophic forgetting. I finally published the first pre-print of my early experiments: https://doi.org/10.5281/zenodo.20064617
Now I'm working on expanding the work into more parameters and improving performance. I just finished an extremely harsh test of a Nemotron-flavored RVW that consisted of stretches of a random assortment of domains interspersed with long runs of single domains. Across all of it the model didn't forget (and actually improved on some of the more challenging domains). PPL on SmolTalk is still in the ~18 range, which I'd like to get lower, but this is all with only 4B params.
Currently, I'm training a Llama 3.2-flavored RVW with only about 2B params to see how that turns out. Depending on results of that, I may take it to Gemma 4 next.
Research grade orbital mechanics, specifically of asteroids/comets. I've been working on it for 4 years now, finally tried using some AI tooling the last few months and ended up vibe coding a fun little visualization.

After quite a few years of coming up with and implementing 'great ideas' but not being able to follow through to making them revenue generating products, I'm on my best bet so far.
I always wanted to build a real-life puzzle game, which is app/mobile assisted. Had yet another eureka moment, and built a usable prototype (backend plus iOS app). Good feedback from a small circle.
For a while I was aware of someone (I knew by sight) who worked in the same sort of subject matter (but a non-tech). I approached her, we had a coffee, I pitched the idea and how she could bring it to life, as I made the tech side. She jumped on board.
We're two and a half weeks in, have gone full speed and are making something great (for our audience). My future co-founder is amazing, great insights, opinions, drive. We're potentially launching in a couple of weeks, a free/MVP version of a puzzle game.
I've been through many iterations of trying to get something off the ground. Tried tech co-founders, and the last years of going solo (very hard after you've done the coding). But this now feels right. A puzzle app/game for every day people to have some fun. And a future co-founder whose life is outside tech, who's bring a sort of fun energy outwith let's make loads of money or isn't the framework/AI cool.
Balance is good. Contact with reality is good too :)
Cool. What’s the game?
I’m building a blackjack card counting tool for people to learn how to count and how to identify games that are winnable. It is designed to take a completely novice to an advanced, winning card counter, using a Duolingo like approach - mastery based learning across sequential modules. Minus the ads and dark patterns.
That sounds super cool! When you say Duolingo do you mean spaced repetition? If yes, have you identified what type of spaced repetition approach you will take?
I'm continuing work on my daily procedural logic puzzle, Ruly.
https://playruly.com.
You play by setting rules onto a small grid of numbers to maximise your score.
My focus the past few weeks has been on refining the difficulty by experimenting with different rule types, and improving the UI.
I'm pretty happy with the look and feel now but feedback is always welcome, and I'm especially keen to hear what you think of the level of difficulty of the puzzles. It's a tricky balance to introduce variety without adding complexity.
There's a (very) small contingent of daily players now which is really motivating.
Your comments very welcome.
Float-explorer, a tool for generating very precise assembly programs to explore the darkest recesses of floating-point behavior on your processor without having to bully the compiler into generating the code for you.
And when I say darkest recesses, I'm not referring to "0.1 + 0.2 != 0.3" (which is fairly well-known) but things like "so when you turn on denormal flushing, how exactly are you defining it because there's at least three different definitions..." Or also "does my emulator actually emulate floating-point behavior correctly, or is it delegating to the current hardware which might have a slightly different definition?"
I'm making a program to build Magic: The Gathering decks from first principles of card data, no reliance on user-posted deck aggregation or EDHREC, and no AI. A slew of internal knobs exposed.
We are working on making our programming language BAML turing-complete. https://github.com/boundaryml/baml
It is a language that is embeddable in other programming languages, with the type system similar to typescript, and a runtime that is similar to Go.
People use it currently for structured outputs with llms but soon we will support orchestration and more.
We are letting some users have an early access preview! Let me know if you are interested in hacking with it!
I do calisthenics 3×/week plus Ironman 70.3 prep, which means my training lives across Garmin, Polar, Withings + FIT files and front-lever sessions that no mainstream app models. So I built one that does both (and have been using for the past 4 years+): logs custom strength moves (front lever, FLAC, ¾ pull-ups), aggregates the connected devices (Polar, Garmin, Suunto, Withings, Apple Health) into one weekly view. Currently trying to see if can integrate some AI insights to my training routines. App is free for now as it does not cost me much (only servers for now), comment / use cases welcome: https://obitrain.com/
Why so many different devices? (Assuming this is the only reason there could be this much sprawl)
Device based strength tracking is still so weird to me.
Have you seen that meme template, where the midwit wants to use a thousand complicated things to optimize their experience, but the grug and the genius both keep it simple?
I think this is a perfect example... somewhere out there a genius and a grug are happily exercising together for the simple joy of doing so and feeling good in their bodies, and nearby is a midwit with the GDP of a small village worth of wearable electronics wondering where the joy has gone as he laments the 0.1% of VO2MAX he's dropped since his last gadget-run.
I haven’t trained for an Ironman but have for a marathon. I do think some metric oriented work is helpful! But I laughed at your post. Happy to see both sides.
In this case it might not be as complicated as it seems, they might be using a Polar device for workout tracking, Suunto for marathon training/hiking, a Garmin as daily watch (payments, music etc). Add to that a Withings scale and an iPhone, and you're dealing with a melting pot of apps.

my embroidering is going fairly well now, but i need to be able to figure out what floss to buy.
the general idea is to take pictures of birds and mountains, and use a bunch of colour-theory-from-minecraft
to first meanshift a bunch of the image to come up with a lower colour resolution image, then to match that to dmc threads
but then i also want to use tools like the axiom mod to fill in gradients, and to do hue shift/temperature changes to represent shadows, like how bdouble0100 uses purples as a shaded green, rather than a darker green.
ive also been using it to see how the claude code for web setup works, and it feels real poor compared to the cli.
the main problem i think i need to pull to local and do my own code for is the colour sampling from the oklab space. when i try to create gradients from colours already in the list, i ve got a visualization of the line its aiming to follow, but its picking the next colour and placing it out of order vs projecting to the line.
likely my biggest issue is that claude and the like are still bad at thinking in more than 2 dimensions, but i think my vocabulary is also subpar for giving the feedback either in clear linear algebra or colour theory terms.
next idea is for when thats done is to make a mod that turns a survival game into a roguelike - in the style of the hades 2 challenge runs, so i can play a session of the game in a certain biome without having to do all the grind first to get there on a new character.
Just implemented Landlock + seccomp notify based sandbox in PMG. A tool to protect cli package managers against malicious packages. There were quite a few quirks involved due to Go routines when it comes to handling messages from the kernel.

I'm working on https://engine.build
It's a durable orchestration system for AI code generation which solves the problem of not being able to trust LLMs to complete long running (and high quality) implementations without having to babysit them and monitor the process, which is what I think is the most exhausting part of coding with AI.
You start with a spec or programmatic task list and the engine runs the whole workflow: implementation, verification, review, fixes, and finalization.
It treats agentic coding like a durable CI-style process, with state, retries, reviewer feedback, commits, and auditability built in. It's externally orchestrated, meaning it's not the agent running the loop, it's simply agents being used as tools and spawned in the loop as needed without awareness of the loop itself.
It's going to be open sourced soon and it's not meant to replace your IDE or Agentic Harness of choice. You keep using codex/claude code/open code/cursor/pi whatever you want and simply delegate the actual implementation to the engine, through MCP/CLI and other integration points.
It supports any LLM provider so you can have GPT 5.5 implementing and a mix of Opus 4.7 / Deepseek v4 Pro / GPT 5.5 reviewing at every phase for example.

I'm working on a general repo shape/structure linter (language agnostic)[0] - the idea is to enforce things like directory structure, existence of various files (LICENCE, etc.), file naming patterns, jsonpath + schema over json/yaml/toml, absence of potentially malicious unicode. It comes with rule bundles for various languages/presets which can be combined and extended. A goal is for it to be very fast, and useable on huge monorepos. I noticed myself having to add various forms of validation/scripts when coding using AI, and decided to build a reusable, fast tool for this purpose instead of rolling validation scripts for each project.

Acoustic diagnosis of electrical problems on the electric grid!
I'm building a tool that allows you to determine the health of an electric transformer from only your phone. It tells you:
I used to be a submariner, so my professional background is in power plants and sonar analysis, so I'm getting to combine the two in this.
Acoustic diagnosis of electric issues is FASCINATING, and it feels like there hasn't been a lot of research into this, so I have been slowly chasing down various acoustic patterns I find and try to derive them from first principles of physics.
I'm making an iPhone app for it, and Xcode has been truly awful: non-deterministic, crashing all the time, and error messages that tell me absolutely nothing. I would like to use xtool, but it doesn't have the preview, which I need for debugging.

I've made https://rankr.click
It's a little web application that allows for the ranking of all kinds of abstract entities. Think of the merging of Goodreads for books, Vivino for wine, Letterboxd for film, etc. This will allow you to instead rank whatever you want across a variety of different categories in a single place.
Using your rankings across all these different fields, you can draw analysis of what you like, and in future I'd like to add a little personal (not an ad) recommendation engine to help you find new stuff based on your actual interests across loads of different categories.
From a technical point of view, its been a great learning opportunity on how to fully host a complete stack using an opiniated, but cross-platform orchestrator, allowing me to host this wherever (bare metal VPS, homebrew system, cloud provider) in a flash.
You might want to add a home page that doesn’t require a google sign in so that visitors can see the product before any commitment
Backend dev gets in a fight with frontend devs. Vows never to built sane UI for his remaning lifespan.
I made a Python tool to build distroless container images for projects managed by uv. It draws inspiration from Ko from the Go ecosystem and works with/depends on uv from the Python ecosystem, so I smashed them together and called it Kuvo: https://github.com/hxtk/kuvo
It’s a hobby project in a very early state where it technically works but it’s missing several things I think it needs before I’d use it for anything serious. As of right now it isn’t even complete enough to dogfood a minimal container for itself without an intermediate base image because it can’t target a platform compatible with the distroless uv container image.
I'm working on a diffusion-powered UI design tool. My short term goal is to make AI-designed UI not look like Tailwind. My long-term goal is to be Figma, but powered by diffusion.
https://diffui.ai
I quit Figma about 4mo ago to start working on this, and the gpt-image-2 drop really legitized the bet. I recently release Brands for diffui, which let you establish a design system and consistently generate with it. I made a Brand out of the recent UFO files release, which allow for some really fun designs:

I'm building Deptheos (https://github.com/ryanmitts/deptheos), a photography/macro focus stacking program.
It works on MacOS, built with Swift and Metal. My goal is to make a super fast, and free, focus stacking program. I provided a notarized MacOS DMG for the initial release, but if built yourself, it will run on an M4/M5 series iPad Pro as well.
The core ability I wanted was to support RAW files as inputs, with DNG files as outputs. This is done using either LibRaw, or Adobe DNG Converter (runtime options).
I have been really into macro photography the last couple years, and have been slowly working on trying to build my own program to handle the focus stacking.
Very cool! Do you know Thomas Shahan's work? He once contributed his woodcut artwork to a videogame, so he does seem very technically curious. I bet he'd be interested in trying something like this out with his own work and providing feedback...
I'm mostly diving head first into formal methods again. Mostly TLA+, but a bit more Isabelle as well.
I haven't really forgiven myself for dropping my PhD; I think it was the right decision at the time, but I also kind of wish I had pushed through it. I'm going to see if I can at least get a few papers published.
I've also had some fun getting Claude to create LSP servers for different languages, which it has been pretty good at, and that's nice; having good integration with Vim makes a language a lot more fun for me.
Oh, I also presented at LinuxFest two weeks ago: https://youtu.be/HmcVJWyOwJQ?t=6623
I continue to be working on kei, my cloud->local photo/video sync engine.
iCloud Photos is fully baked along with implementing their completely undocumented SyncToken. I’m doing some QoL work in the next few weeks, tightening up some early architecture decisions, and then adding more providers (Immich, NextCloud, Google Takeout… else TBD).
Since last time I posted this, two other people contributed and I’m almost at 100 stars! That’s some dopamine.

I wanted a faster, easier mapping app to plan motorcycle rides for myself and with groups, so I finally bit the bullet and started building my own at the beginning of this year.
I got to the MVP state which was useful for my personal use case in about a month. I took it further than that as a learning exercise and as a means to share it with others. Some features that came later are live cursors (like Figma), elevation chart and grade overlay, and QR-code enabled collaboration links to make in-person sharing simple.
Check it out! https://plotalong.app
Figuring out the exact UI/UX I wanted was the hardest part. I did the branding myself, handdrawn on paper, traced in Procreate, and vectored in Sketch. Fast iterations and a good test suite made it possible to try lots of different approaches and refine the one I liked the most. There are roughly 4000 unit tests and over 300 e2e tests that run on multiple environments with fully automated CI/CD.
I’m using Mapbox for the frontend and the whole app is basically just a monolithic Cloudflare Worker. Claude pretty much implemented the entire thing. I got a lot of mileage out of self hosting a Gitea project and recording all my planning sessions as Milestones and Issues. Claude has his own account without admin privileges. The process of managing a team of agents to build this practically autonomously was a bit jaw dropping and eye opening to be honest.
I would love to hear from other pleasure & sport drivers about the features they use or want the most in a routing app. I have an Android app in Play Store review, if you’d like to be an early access tester shoot me an email at my handle @plotalong.app
Very nice! Does the sharing feature allow live location sharing? That seems like it would help a lot, especially when group members are in separate vehicles.
No, and while that does sound like a pretty obvious feature I should clarify the app is about planning, not turn-by-turn directions. You can open Plot Along routes in Google Maps, Apple Maps, multiple GPS formats and more
The idea is everyone opens the same route for coordinating and there’s just one source of truth for the group. And then when you’re all about to hit the road, everyone can use the nav app they’re already familiar with (or that’s built into their vehicle)
I will tackle the navigation aspect at some point if I do keep up on feature dev, though!
Brilliant! I definitely felt the lack of appropriate solutions.
I've been building this "general problem solver" (will likely focus on math problems first) that uses a special kind of orchestrator to direct/structure the problem solving approach in accordance with how many 'rounds' remain and other aspects of problem context. It does this largely by influencing the behavior of specialists.
Just posted a first early demo and sample orchestrator system prompt yesterday: https://x.com/Westoncb/status/2053429329233895857
You initialize the system with an objective and a number of rounds to run for, and it loads the current config (orchestrator + specialist prompts and LLM configs) and begins working on it. You can manually step one round at a time or just let it run.
Rather than accumulating a single long work log/context, at each round specialists apply patches to a number of named 'artifacts' with different roles (e.g. uncertainties, dead ends, findings), which are injected into prompts during subsequent rounds.
The engine is written in rust and there's a web UI (and CLI). You can use the built in config editor to define specialists (and their prompts), what the artifact set is, orchestrator prompting etc.
Building an open-source ElevenLabs-like AI voice platform called OmniVoice Studio.

I got most of my must-haves for my car maintenance tracking web app out of the way. it already does everything I wanted all the paid alternatives to do, even has SSO integration (only Google OAuth for now). the other must-haves, I do actually need, but I think they can wait. notifications, and an export mechanism for my history (including file attachments). for now I think I'll focus on the other things I've been putting off, like upgrading my car's audio.
Still building https://FastComments.com :) I'm planning on launching a desktop app for it soon with a combined forum. So you could have a community on something like discord, but all the chats are indexed and searchable through a web forum style interface as well. The desktop app is a native C++ app so no electron :)
I'm also working on launching https://watch.ly (network/fs sandbox with human in the loop for ai agents), mostly waiting for the entitlements from apple at this point...
oh and I launched https://dirtforever.net recently to keep Clubs going for Dirt Rally 2 without the EA servers. Learned about the egonet protocol and made a server.
working on https://heylife.ai, an app that gives you proactive advices based on your calendar/taste/hobbies/location
let’s say you are arriving in paris. it will send you advice on how to get to the city from the airport. big soccer game in an hour? will send you advice on prepare it.
you don't need to ask, it will give you before / when you need it.
now working on the sandboxing and scheduling of the advices. releasing it this week if anyone want to give it a shot. (it will be paid only)
* Tab Wrangler GitHub Project: https://github.com/tabwrangler/tabwrangler
* Tab Wrangler for Chrome: https://chromewebstore.google.com/detail/tab-wrangler/egnjhc...
Continuing to work on Tab Wrangler, an extension for both Chrome and Firefox that has been available and open source for 10+ years. It auto-closes tabs when they have not been active for a configurable amount of time, similar to the feature built into Mobile Safari but more configurable.
I have been maintaining it and in the past few months added features that had been requested for a long time.
https://gitlab.com/gabriel.chamon/orisun is a Gitlab-first methodology I've been cooking for the past month that brings epics and work-items to the repository. Present your project, describe your domain and it will produce meaningful epics and work-items that are automatically reflected into Gitlab kanban board using https://gitlab.com/gabriel.chamon/ci-components/-/tree/main/... in Gitlab ci.
https://github.com/abi/lilo I’m working on Lilo, a Telegram AI agent that can remember things, store files, track your TODOs, manage your calendar, conduct research, build apps, send you reminders and monitor things for you.
I’ve found it super useful in my personal life and is pretty much my #1 app.
https://www.GetSetReply.com
I'm actually looking for beta users! GetSetReply is a SaaS I've been building. It does two things for small businesses:
1. It helps you get more reviews by sending automated requests for reviews to your customers over SMS and/or email after they purchase from you (PoS Integrated / Manual Sending)
2. The second is helping you reply to the reviews you already have with AI-generated drafts in your brand's voice that you can send to Google/Yelp/TripAdvisor.
I'm very grateful to anyone who is willing to test or provide feedback. If you create an account (it's free with no credit card or integrations required), I'll reach out! Or you can email me via my email in my profile.
Fitting lines to 'xray' scans of buildings - turning pixels into vector art.
Lets say you have a complex industrial plant, or datacenter you want to upgrade.
You scan it with lidar and get a pointcloud and 360 panorama images. This gives you a large dataset, but what you really want is a floorplan, a lite CAD plan showing the racks, cable trays etc.
You take the scan, slice the pointcloud and make an ortho image .. it really looks like an xray of a building from the top down.
Then someone has to manually trace that in CAD to make a useful 3D model they can use for designing the upgrade.
So Im automating the boring manual part - turning the xray plan pixels into vector polylines, using machine learning.
One of our clients scanned their datacenter, and we generated a floorplan that shows all the rack box positions, cable trays, pipes etc.
Other examples : drawing the weld lines of patches in steel storage tanks, drawing in all the steel girder beams in a scan of an old railway bridge, or the windows, doors, ceiling pipes of a commercial realestate refurb.

As part of this work, were looking at running our custom machine learning kernel on multi-core x86 CPUs.
I've been using https://github.com/gchamon/buzz as an opportunity to have a WebDAV with tight integration with real debrid, jellyfin and opensubtitles. It solves the requirement of jellyfin for having a single file per folder even if the original source had many files in them, adds confirmation for removing entries from debris, has an archive so deletions can be restored, a simple but powerful integration with opensubtitles and a functional logs UI. It's also an opportunity for me to review web design concepts and experiment heavily with coding agents, both local and SOTA.
Ménière Memo, a web app for logging and reviewing Ménière's Disease episodes:

I'm working on requested features for my social wishlist app https://thingstohave.app: image uploading, passkeys and more clear list organization UI. Everything is in polishing stage, and I hope to release these before June.
Big thing I made recently is moving it from SvelteKit to Hono + Inertia + Vue.
I like SvelteKit, but I was struggling with stability in active development periods, and writing proper tests was very hard due to mocking all the magic, especially outside trivial testing tools.
Now the whole app is straightforward Hono MVC with Vue powered UI. Logic is easy to test, and all UI states exposed in Storybook.
I wrote a custom adapter that makes Inertia run on Hono, and coincidentally same thing was released by Hono author itself as official module, which is great sign for adoption!
So, try Inertia – it is a best of both worlds. You write MVC backend as you like, and use modern JS frameworks for templates.

I’ve been building an uptime monitor service for a while now, something that is genuinely reliable and only alerts you when something is actually going on. Also comes with very pretty status pages!
Free tier is enough for most users, paid tier just exists to gate the stuff that is expensive to run like SMS alerts.

https://klados.bio/ Prod site is pretty behind dev branch, basically abandoned normal CI / repo hygiene for the moment
I've been working on an update to my flashcards app for over a year and half now and I'm finally nearing completion. This is for Mac and iOS only and the app uses Core Data with CloudKit for syncing its data, which has been interesting learning the ins and outs of. (For instance, CloudKit can throttle your sync if you have too many objects, so I ended up having to create snapshot objects to carry lots of records in bulk which I then expand in a local SQLite database to get around its limitations.)
The app has a lot of UX details that I've really enjoyed working on. I wrote up some notes about it here: https://www.freshcardsapp.com/3/
Separately, also working on a Zettelkasten notes app that pushes you to make small, atomic notes that you can organize in "collections" to provide structure beyond just hyperlinking in the note text: https://understory.ussherpress.com/ This has been a lot of fun iterating on. I started with a Miller Columns UI, like Finder, to visualize the graph of connections between notes, but I found that it was too overwhelming to use, so I scaled back and went with a more Notational Velocity-like quick search bar with note addressing. The app UI mimics a browser because I found that it works really well for something like this. I need to polish it a bit more and want to find people who will give it a beta test to help me iterate on the ideas some more.
I am hacking on an alternative to Builtwith: bloomberry.com. Unlike Builtwith, you can search for companies that use any backend/backoffice product such as Jira/Atlassian, and Github (enterprise/free).
I made an end to end encrypted provably private LLM Router https://trustedrouter.com/
Been using that to power a Mac mini alternative I’ve been making https://jperla.com/blog/quill-one
I've been working on https://www.photogenesis.app
It's an iOS & Android app that applies various generative art effects to your photos, letting you turn your photos into creative animated works of art. It's fully offline, no AI, no subscriptions, no ads, etc.
I'm really proud of it and if you've been in the generative art space for a while you'll instantly recognise many of the techniques I use (circle packing, line walkers, mosaic grid patterns, marching squares, voronoi tessellation, glitch art, string art, perlin flow fields, etc.) pretty much directly inspired by various Coding Train videos.
I'm currently fighting Garmin's wonderful Connect IQ watch app platform (it's horrendous).
I'm working on <https://untether.watch>. Trying to shift 20-30 micro phone interactions to the wrist per day to ultimately reduce phone use. Dumbphones are too extreme - you need a smartphone for certain day-to-day activities (banking etc.)
The watch is a great form factor - it's got a crap screen (MIP), the ergonomics are awkward (rotate and look down), it has limited capabilities. But that's the point! Do essential quick actions and leave the phone out of site.
Requires Android companion app to do the heavy lifting. Use the (head)phone mic and STT to reply to any android notification and make notes. More features to come.
Garmin's SDK is seriously challenging. APIs are often broken across firmwares, limited developer tools and testing is tough.
I agree it sucks! I thought about vibecoding my own app just to reliably get my data out.
https://github.com/lvlup-sw/exarchos
It's an SDLC workflow harness for agents. Instead of using skills to encode my typical workflows (e.g., create PRD, then create plan using TDD, then dispatch subagents, etc) I've built a concurrent event-sourced process manager to handle it.
I am building https://aweb.ai (https://github.com/awebai/aweb)
I was tired of copying/pasting between agents, so I gave them identities, and tools to talk to each other and share tasks. I've found it so useful that I've left my job as the CTO of a German startup to focus on this.
The identities are public-key DIDs with DNS as the source of truth, as well as team membership. I also run a public registry at https://awid.ai (also OSS).
Bor - Linux Desktop policy management ( https://getbor.dev/ ).
In short, it unifies the configuration of different desktop components as policies ( dconf, Kconfig, polkit, Chrome, Firefox, etc.. . It's LGPL.
You can check my slides for the upcoming Tuxconf conference this Friday: https://getbor.dev/publications/tuxcon2026/
Cheers! Blago :)
I'm building https://clipper.dev
Docker is...quite slow with large images. I've built a registry+pull client+buildkit builder to make it better. It splits apart layers, allowing for files to be shared between related images. In a robotics context, it can make pulls 10x faster. And in a cloud context, the format allows for pulling an image in 15 or 20 seconds instead of 60, without having to do a FUSE w/lazy pulling. Builds are faster, I store 7x less data due to better deduplication, I can run security scans faster due to not having to unpack tarball layers, etc, etc. I want to be the default registry for all ML related work, in the future.
Copy fail and dirty frag killed containers, pivot out of shared kernels now
You're right - all of mine instantly stopped working and I'm just gonna switch over to pen and paper.
I'm working on MedAngle, the world's first Agentic AI Super App for premed, medical, and dental schools and recent graduates - young doctors.
MedAngle is literally everything one could need, personalized to their curriculum across 4-6 years of medical school. Quizzes, videos, notes, flashcards, reminders, scheduling, performance, search, and more.
Our Super App is comprised of MedGPT + MedAgent + Spaci (futuristic spaced repetition), which serve as layers over our massive collection of features such as the Smart Suite, Learning Library, Clinical Corner, Tested Tools and more.
100k+ users, 10s of billions of seconds spent studying smarter, invite only. Bootstrapped, growing nicely. I lead a team of top medical students and doctors.
I'm working on an AI-native email client that organizes, prioritizes, and drafts emails for you.
The vision is for everyone to have an executive assistant that manages their email. It's built for people who spend hours in their inbox every week.
It has automatic prioritization, split inboxes, snippets, bundles, automatic follow-up reminders, and an AI agent that can do stuff for you -- without deleting your emails.
If you've read this far, I'd encourage you to give it a try and let me know what you think!

I’ve been working on Broadcast since Sept 2024:
https://sendbroadcast.net
It’s a self-hosted email marketing/newsletter app. The basic idea is: own your subscriber database, run the app on your own server, and send through SES/Postmark/Mailgun/SMTP instead of being locked into another SaaS.
Not trying to be “Mailchimp but cheaper”. It’s more for technical founders, agencies, and consultants who want a boring, controllable email tool they can deploy for themselves or clients.
I’ve kept the changelog public because I wanted the work to be visible: https://sendbroadcast.net/changelog
My buyers are typically people who want to own their data and are in regions that have strict data privacy regulation/laws.
Interesting fact: This was my real last project where v1 was built by hand before AI coding became the norm in the software industry.
I built on online multiplayer boggle game back in 2008 that somehow drew a lot of users, many of whom still play every day after 17 years. About a year ago I started a rewrite from scratch in more modern technologies but stalled out after getting to about 80% of the way there. A few months ago Claude enabled me to finish the remaining 20% and was able to relaunch mostly successfully! It's been tough though. I'm a dad with three kids and use Claude all day at my day job and my interest in working late isnt always there. But I'm eeking my way to something that hopefully can stay up for another 17 years.

I wanted to make it easier to quickly see/study trending articles on Wikipedia because they tend to make good topics to know before going to trivia night.
I've had the domain for awhile, but just made the app recently on a whim.
I use Wikimedia's api to get the trending articles, curate them a bit, add some annotations to provide some context, then push to deploy the static site.
I've had public dotfiles at https://github.com/nickjj/dotfriedrice for a long time but recently branded them and after having run native Linux for 6 months, I added a desktop environment based on using niri and Arch Linux.
It can get you up and running in a few minutes with an installer that can set up a new system or keep an existing system up to date. There's also a command line version that works on Arch and Debian based distros (including WSL 2) and macOS. I use it on my personal devices and a company issued MBP.
I'm not going to lie, I've been using computers for 25 years and this is the happiest I've ever been with using 1 machine for everything (software development, media creation, gaming, etc.).
Since getting laid off in Feb, I've been spending my free time polishing up my word game Gram Jam (https://gramjam.app).
I finally finished the (monumental) Svelte 4 -> 5 migration that had been getting dusty for the last year. This unlocked a higher performance ceiling for me to polish my animations and UX. Now I'm revamping my onboarding experience and taking another crack at marketing and promoting it. Last year, I was focusing on setting it up as a PWA and integrating Sentry monitoring and Stripe integration. All important stuff but not what got me excited about the process.
I've been pretty tied up with maintenance and admin work, and haven't gotten a chance to work on the actual game design in a while, so I'm very excited to return to that part of the project soon. I have ideas for new puzzles and modes spilling out of my ears and I feel like with LLMs my prototyping can finally keep up with my brain, now that I have a robust foundation for the game architecture.
I track wait times at the Berlin immigration office. I just added a graph that shows how wait times improve/worsen over time. I generate the SVG without any external dependencies. It was a fun exercise.

I wish I had more time for such projects, but since AI is now capturing most of the traffic, I am losing a lot of my income and I have to make up for it. It's a huge distraction.
I'm currently working on BetterCapture (https://github.com/jsattler/BetterCapture), which is a lightweight (~4MB size and low memory/cpu footprint) screen recorder for macOS that lives in your menu bar. It supports ProRes 422/4444, HEVC, and H.264 — including alpha channel and HDR. Frame rates from 24 to 120fps. System audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.
No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac.
I'm currently planning and designing a plugin system, so others can contribute new functionality without affecting the scope of BetterCapture itself - which should stay as small as possible.

I'm working on World Watcher (https://worldwatcher.live). It's an interactive map of livecams around the world.
The idea is to have a better experience for navigating livecam streams that are publicly available on YouTube. There are a few livecam aggregators that include maps, but I never felt that any of them were satisfying, as they always require you to open new pages to watch the streams. On World Watcher, you can jump from place to place seamlessly.
You can also filter the streams by type of place or features, for example beaches or cams with audio. And if you don't know where to go, just try out the Explore button.
I've been working on my open source integration-platform-as-a-service (iPaaS) auth proxy. It provides an embeddable integration marketplace where users can connect 3rd party apps, and it provides a proxy endpoint to the host application to send authenticated outbound requests. That way token refresh, audit, etc stay with this system and frees the host application/agent/whatever free to just focus on the business logic.

Greetings!
I've been working on something in the vein of a indie game for a little over a year now. It has been a passion project, but I'm starting to come around on showing it to people.
I am a big fan of Telltale style narrative games. I think Baldur's Gate 3 was the biggest revelation of this for me. Taking that branching dialogue and freedom of choice, and tacking it on to a fun combat system was just everything.
When text based GTRPGs started popping up, I found it hard to connect with them stylistically. I found that I needed the multimodal stimulus of visuals and audio. This led me to start building something, and it ended up being somewhat of a cross between a Telltale game, a Visual novel, and a TTRPG.
Orpheus (https://orpheus.gg) is a fully on-the-fly generated tabletop simulator, with graphics, audio (TTS), and the freedom you can usually only find at a real TTRPG table. That means you can play a sci-fi, fantasy, or even a modern setting in your campaign. The assets are made for you as needed. It runs in your browser so nothing to install or tinker with.
Getting the harness right so the AI GM can stay coherent and organized has been the biggest challenge. It took a lot of iterations to get it to a point where it could understand the scenes it was building as the player changed them.
I've built it to be played with either a keyboard or a gamepad so you can play from your couch. You can switch between them as you feel like it. There is a 3D tabletop for combat, full character sheets, dice rolling, lore tracking. I want it to be dense.
Mostly, I’m looking for people who want to try it, break it, and tell me what feels magical, confusing, boring, or broken. My biggest roadblock currently is that asset generation is relatively expensive. I'm currently mulling over whether a playtest would allow for a BYOK setup so people could try playing as much as they'd like, or if I should add turn limits.
You can join the playtest waitlist at https://orpheus.gg/ -- and I just setup a discord (https://discord.gg/pychWyzf) that I will use for early playtests. (Just me right now! Come hang out!)
Why not generate some asset libraries to help with some of the rote generation? You could theoretically serve the same asset for a pack of rats to multiple campaigns.
Yes! I am doing a lot of this where it won't break the illusion. Not everyone needs a unique innkeeper generated in every town, but I want to avoid that "Officer Jenny" effect like in Pokemon where she looks the same in every town they visit.
I have a private vs public flag for assets that I'm considering more unique or sensitive, at the AI GM's discretion. I'm using embeddings from there to try and parse if an asset already exists in the public pool or not, and reuse it if possible. The thinking is that eventually I will have pretty decent asset coverage on most standard campaigns. I can't account for people going way off book though.
I have an asset pipeline that tries to determine player intent and pre-generate assets before they're needed. That way we can attempt to hide the "load screens" like retro games did with elevators. I have a kind of sliding scale for player coherency, and if the player has too many "misses" on the pre-generation pipeline it will increase its requirements for when it starts generating.
I may have wildly over-engineered this but I love it. =)
Super cool project and I love to encourage this as I personally think llms in games have not been utilized to their potential quite yet.
I've been the DM of a weekly campaign with the same group of friends for nearly a decade now. Over the past few years, I’ve seen a lot of attempts at AI meets D&D, and most of them suffer from fairly pedestrian puzzles and stories, and don’t really compare to what a decent, semi-competent human writer can come up with.
I'd love to see a more modern day attempt at something like Bioware's Neverwinter Nights - which was designed so that someone could create a campaign, and then the game would provide the behavior, pathfinding, assets, and everything else with a virtual (or human) DM behind the scenes. You could still tell a human-driven story, but the engine would do a lot of the heavy lifting.
I agree, there is no way to perfectly capture a real table with your friends. This is more an alternative for when life gets in the way of meeting every week.
I think a lot of those attempts you mentioned try and brute force the problem or trust the AI too much on what to generate.
A lot of the same problems that AI coding agents run into also apply to this problem. You have to really manage context (avoid sending a novel at the model) and enforce strict rules in the "engine". The hard part is world building that is consistent without railroading the player and forcing specific paths. I have an agent (for lack of a better term) that manages arcs across each tier. World arcs (nations, factions), player character arcs, NPC arcs, individual scene arcs, and location arcs (towns, cities, dungeons, etc). By prompting all of these as tight, individual arcs with flavor and context peppered in as needed, you end up with stuff that is more compelling. It has to be loose enough that you don't railroad the player. When you decline that NPC's quest, down the road that might have changed the overall arc for a town in a meaningful way.
I won't pretend that I've perfected anything but I have definitely noticed a spark in its writing and world building that I personally have really enjoyed.
Yeah I'd agree that I think AI can at least work provided you manage the context properly, multiple top-level files establishing consistent world state, all that jazz. KoboldAI and SillyTavern both do a pretty good job of maintaining internal consistency around longform interactive fiction.
OTOH, that means that the underlying story is that much more important. I think a lot of people mistake coherence for novelty. Biggest offender is puzzles - oh god do LLMs absolutely blow dire wolf chunks at coming up with organic and interesting puzzles.

We're working on AI user testing, to make it dramatically faster and cheaper for product managers and dev teams to find major usability issues with web sites. Give us a web site and a task users would do (e.g. "Add a pink shirt to the shopping cart"), and we have some AI users try their best to do the task. The output is a report with a prioritized list of problems identified, plus narrated videos that show each AI user trying the site.
If you want to try it out, we offer some free credits at https://fuguux.com
Any feedback you have would be incredibly helpful! We're considering more kinds of reporting, support for QA testing, better integration with CI/CD, and more.
Note: we don't want to replace real user testing, but rather complement it. With AI user testing, you can get quick feedback on potential usability problems in hours for a fraction of the cost, making it so you can iterate much faster. We advocate doing user tests with real people to understand problems that require domain knowledge or nuance.

I built BookDMV (https://bookdmv.app), it watches DMV offices for open appointments and either alerts you or books one automatically.
For the past 2.5~3 months I've been working on a 2D/3D VFX (visual effects) editor dedicated to mac and iPhone/iPad, it was on my never ending list of fun projects to build and a perfect excuse to learn agentic coding on a domain of expertise (written in Swift/SwiftUI and Metal).
I wrote a blog post about my process: https://sxp.studio/blog/subjective-building-a-native-vfx-edi...
...and you can download the app here if you're curious (the app is free!): https://subjectivedesigner.com
Next project is going to be a pivot of that project into something related to creative coding and agentic :-)
I’m building OneBusAway Cloud, which you can think of as being Heroku for public transit.
https://onebusawaycloud.com/
It’s a project of the non profit Open Transit Software Foundation that we’re using to fund our other initiatives, like bringing realtime transit information to billions of people around the world.
All of this depends on a bunch of really cool open source projects we’re building, like Maglev, a Golang server that can power realtime transit apps. I wrote up a blog post explaining how to set it up here: https://opentransitsoftwarefoundation.org/2026/04/setting-up...
We’re always looking for volunteers, especially non-engineers. https://ossvolunteers.com/organizations/open-transit-softwar...
I built something in this space.
Do i understand correctly that the product is a white label app for public transport providers that riders can download to get arrival data?
Do you think people will download an app for each bus/train? Isn't it better to integrate with google maps or equivalent?
There are several different ways that OBA can be deployed and used for a transit agency or a group of transit agencies in a given region. I'll give you four examples, but this isn't an exhaustive list:
1. The Puget Sound region, where a regional transit authority, Sound Transit, currently maintains their own OBA servers on behalf of a dozen individual transit agencies. Sound Transit piggybacks on our official OBA apps which you can find in the Play and App Stores. The official apps also work in 10 other cities across the US. This is the ideal for us—and transit riders, imho, and similar to what you see with apps like Citymapper or Transit.
2. New York City, where MTA runs their own OBA servers that power their own branded app and realtime signage throughout the five boroughs.
3. UC San Diego, where the university is using OBACloud to power real time transit information systems for students on campus.
4. Republic of Cyprus and Malaysia (yes the entire countries), where enterprising individual developers have set up their own OBA servers to power realtime transit information systems for their fellow citizens.
The underlying OBA server provides a rich set of REST APIs that make it much easier to build a public transit app than using raw GTFS and GTFS-RT data: https://developer.onebusaway.org/api/where/methods
We also have SDKs for many major languages so that agencies and independent developers can build their own apps on top of OBA servers without having to fiddle around with the intricacies of our APIs. https://developer.onebusaway.org/api/sdk
~~~
Integration with Google Maps is important, and a "yes and" solution. I think there's a lot of value in having public transit-focused apps, especially ones that don't have advertising or questionable privacy issues.
~~~
edit: I noticed you're in Argentina. The Ministry of Transportation maintains its own white label version of OBA called Cuando Subo. https://www.argentina.gob.ar/sube/cuandosubo
The Ubuntu DDoS got me to thinking: If we had a critical need to respin machines (like our data center caught fire), we would have been in for a real challenge. We run apt-cacher-ng, but it did nothing for us during the DDoS, and worse: Every few weeks or a month ac-ng will go out to lunch and we have to fix it.
So: ac-ng didn't reduce the impact of the DDoS, but it does lead to impact when there is no DDoS. Worst of both worlds.
So I'm working on an apt-cacher that goes to lengths to keep working as much as possible when the upstream is down. It will check the repo metadata and keeps a list of your "hot packages", and will download those before flipping the new metadata to be live, effectively a snapshot. It won't allow you to download a package you've never downloaded before in the case of a DDoS, but packages that you do download regularly (machine re-installs, apt updates), it will ensure are available in the repo.
I'm calling it apt-cacher-ultra. It is pretty early days, it'll probably be another week before it's ready for a beta. I'm running it in my dev cluster right now, successfully.
https://github.com/linsomniac/apt-cacher-ultra
Working on https://kapturekafka.dev, a desktop app for Kafka protocol inspection. Think Wireshark or Fiddler, but native for Kafka.
Useful to debug local Kafka apps against any cluster, intercepts the traffic, decodes the protocol. You see interesting (and weird) things when you look at the protocol. Still early, though already useful for local debugging when you know what you want.
I'm newly mostly-retired as a VFX software developer & CTO. I'm writing about AI, climate change and more in my blog, https://oberbrunner.com, running Long Now Boston (https://longnowboston.org) to promote long-term thinking, and working through my lifetime backlog of "wouldn't it be great if somebody wrote this" ideas using Claude, at https://github.com/garyo.
You should check out my new open source software build tool, https://pcons.org.
We are working on DBConvert Streams:
https://streams.dbconvert.com
A self-hosted database IDE with built-in migration, CDC, and DuckDB-powered federated SQL.
Mostly trying to remove the annoying gap between "I can inspect this database" and "I can safely move/sync this data somewhere else".
Current focus: resumable large loads and cleaner initial-load-to-CDC handoff for Postgres/MySQL.
https://surmai.app/
I'm working on a Personal / Family travel organizer. Started as tool to allow me and SO to plan a trip together. There's been steady progress over the last couple years. Focus on privacy and ability to self-host. Of course, there is a managed version if one doesn't mind me having access to their data.
Interesting! Maybe making this info avilable to local LLMs would be useful too. Side thought: when we plan big trips I tend to pre-populate google maps with loads of markers of interesting points. I would love to be able to save this offline and combine them with other sources like youtube/instagram clips offline somehow.
I’m working on a story time utility.(https://bedtimebookhelper.com/)
You build up a library from your physical books by scanning them in or discover OpenLibrary books to read in app. Then as you mark books in your library as read, it starts building a rotation and recommending books you haven’t read recently. I’ve been using this nightly to track my son’s 1000 books before kindergarten for the last couple of months.
Currently, I’m working to get the app out on Google Play and adding multiple story time attendee support.

A model framework for an in house suite of models.
From dataset harvest, to training intricacies on CUDA/ROCm to fun HIP kernels. Full circle to inference testing, building it around consumer hardware(the challenge). Using this as a "how it works" deep dive, allowing me to learn more about the how, more than endless papers will. It's a MoE and I'm slowly running a human loop, research, build, correct, research.
I’ve been building (launched in Feb) a home phone service for families who want to put off the smartphone for as long as possible, but still give young kids the ability to communicate via landline. https://chatterboxphone.com
For a long time I wondered how SV startups got such pretty landing pages (here’s a comment I left 2 years back: https://news.ycombinator.com/item?id=37421273). I wanted one for my side projects but couldn’t afford an agency, and the templates online were boring. Creating the page was only half the problem. I also needed somewhere to collect emails for the waitlist.
After AI happened, I built an app (promptfunnels) to scratch my own itch and generate funnels (fancy name for landing pages with a purpose).
Then came the harder part: marketing it. Coming from a tech background, I knew nothing about marketing, so I started reading and came across the $100M Leads book. I realized codifying those principles together with funnels and marketing automation had a real market. My family, friends, and acquaintances became the first customers. A friend joined me as cofounder and we both quit our jobs to do this full time.
As we talked to other startup founders, they kept describing a tangential problem they called GTM. At the core it was the same thing we were solving: marketing for non-marketers. So we pivoted to RevMozi(https://revmozi.com/), which helps non-marketers do both inbound and outbound GTM.
We’re dogfooding the product and coming out of beta next month.
Wish us luck.
> how SV startups got such pretty landing pages
Umm where? They are indistinguishable from each other. Not pretty.
some of them are non existent today. Check the parent thread - some good recommendations(for 2023) on both functional websites and pretty websites. At that time if I recall linear landing page was all rage, and there were many copycats.
A timelapse platform powered by community photos. The idea is to place a mount and QR code at fixed viewpoints around the neighbourhood. People scan, photograph the view, optionally add their name, and submit. Over time, the platform stitches those shots into a living record of how the place changes with seasons.
Just finished the software side using a boring technology and am about to order the materials for the first few locations. Curious to explore photo alignment once real submissions start coming in. Stitching all slightly different angled photos into a smooth animation seems interesting.
Love the idea!
A desktop client for Repomix. Repomix is a CLI which allows you to summarize all the code in a repo in one txt or md file so you can in turn feed it to an AI model for analysis. It absolutely gets the job done it its current state, but it is a personal project so there may be a few rough edges.
https://github.com/KevanMacGee/Repomix-Desktop
It's open source and has no official connection to Repomix. But the developer, yamadashy on Github, knows about it and seemed to like it enough to add it to the Repomix website under the community projects.
I like being able to paste all the code into a browser window and have lengthy discussions with ChatGPT, Gemini and GLM. Doing so in the browser saves tokens over doing it in Cursor or Codex. I like using the Projects feature in ChatGPT in the browser and Notebooks with Gemini because that gives the model context and history on whatever I am working on. It was one part scratching my own itch, one part learning about Python and Customtinker.
It's made specifically for when you just want to get the code and paste it, no muss or fuss. It doesn't have support for flags (yet?) like the CLI because again it is built for speed. Besides, when I want flags, I like using the CLI instead to get granular. Repomix Desktop is for "just give me the code."
I'm a self taught coder so I'm very open to feedback.
Mainly working on https://localhero.ai, automating i18n translations for product teams. Basically runs as a GitHub Action, translating new strings on PRs matching your brand voice and glossary. Got our first fully selfserve customer a few weeks back (found us through the docs). Interesting work lately has been improving how the system learns from manual edits, when someone tweaks a translation in the UI, it feeds back into translation memory and influences future translations in a smart way. Also did stuff like improving our agent skill, so coding agents get glossary/style guide context automatically and they can write source copy that better matches the brand.
Been pushing some new stuff on https://infrabase.ai as well, my AI infrastructure tools directory. Traffic growing steadily from comparison and alternatives pages. Interesting finding is that blog posts rank better but get fewer clicks now because AI Overviews, interactive comparison pages still earn clicks. ChatGPT has also started citing the site more as a source. Adding new content and polishing existing parts of it, added a page focusing on EU based services at https://infrabase.ai/european.
I am working on a task manager that’s way more informative and resource efficient than the windows task manager and works on Linux. It also provides an informative dashboard for docker containers and web servers with proxy support and preference for streaming sockets supporting http and web sockets over the same ports.
WSL support too? Could be cool with a unified thing, not sure if that's even possible though.
It’s just a node app written in TypeScript. The OS specific details come from running the right shell commands.

I built The Daily Baffle over at https://dailybaffle.com with a whole bunch of word and logic puzzles I designed.
There's Truthsorting, a logic puzzle where you have to order logical statements to make them true or false.
Pathword, a puzzle where you lay out letters along a path to spell out 4 words.
Morphology, a clued word ladder written by a different contribution daily.
And a few others!
I've been trying to promote it for a few months but I haven't had a ton of luck, to be honest. The audience hovers around 500 people and growing it beyond that has been pretty challenging.
I have been working on two opensource tools:
https://dhuan.github.io/mock/latest/examples.html Command line utility that lets you build APIs with just one command.
https://github.com/dhuan/dop JSON/YAML manipulation with AWK style approach.
My own browser game. I created a browser game engine and building my first ever game with it. I can’t wait to launch it, I think it’s pretty cool. I’ve been working on it for 6 years!
The tech surrounding the game is awesome, the game and engine are fully deterministic, discrete (not float based), and bit-packed data structures throughout, powers of 2 everywhere for really fast operations, and logic and rendering are fully decoupled.
I wrote a simulator for the game and can simulate 10,000+ games in around 50 seconds on my MacBook M1 Pro. Purpose of the simulations is Monte Carlo method to tune my enemy AI (not LLM - conventional bots etc)
Very cool. I’m also working on a browser game - multiplayer, deterministic, with simulator for PvP tuning.

I'm building a chrome extension that scans everything you read and highlights text if it maps to a market on kalshi. On hover, a tooltip pops up allowing you to drop money on it.

As a data-obsessed golfer trying to get to single digits, I need a tracking app that picks up where Arccos leaves off. So I'm building one: https://shortgamewiz.com (still a bit WIP).
After a few rounds of using it, I already know a few things I didn't before: I suck at right-to-left breaking putts, I baby uphill putts too much, and getting out of bunkers consistently is not good enough if I can't sink the occasional save. So I know what to practice now.
Anydrop.org A zero-friction, cross-platform alternative to AirDrop. If your device have a browser, you can drop text or files to it. Doesn't matter if the device is a pc, mac, linux, phones, tablet or smart tv. There are no installation or login, just load https://anydrop.org on the devices needed. Also support live realtime notepad sync and clipboard for easy share of text snippets. All shares are end to end encrypted.
I'm working on https://www.certkit.io. It started as a solution to handle TLS certificate automation for my other SaaS products, but we realized other people who run on-prem workloads might get something out of it.
It uses Let's Encrypt by default. We use delegated DNS to handle ACME challenge validation (we run the DNS, you just CNAME to us). This means you don't need to give us DNS credentials or anything. And for HA workloads it's great, because there's a central clearinghouse for certificates - so all the machines in your web farm (or whatever) get the same cert, but you don't run in to rate limits with LE.
We're recovering Windows Server guys so we made sure our automation works for painful windows workloads like IIS, Exchange etc. too.
We've had enough interest that we're building it out for real. Just left beta last month.
How is this better than just LE with certbot?
I've been working on a pure Clojure implementation of WebRTC Data Channels (SCTP over DTLS over UDP). The library provides a minimal, dependency-free (except for Clojure itself) way to establish peer-to-peer data channels on the JVM.
I've always wanted this and have used it to experiment with Gemini's cloud agent Google Jules.
https://github.com/alpeware/datachannel-clj
Cool project. I'd be interested to hear your general impressions of Jules (as the somewhat forgotten agent).
Thanks! I've noticed a big jump when they switched to Gemini 3.1 Pro and it really became useful. I like that I can use it from my phone too. It took a bit of trial and error but I came up with a good ralph loop between GitHub Actions and Google Jules using the Jules API. So basically I have Jules extend its TODO.md with the next set of tasks and open a PR then run a GitHub Action with a few checks, auto-merge, and then call back into Jules to kick off the next cycle if there are still open tasks. It then mostly just runs and occasionally gets hang up on some questions that I then answer on my phone mostly just telling it to make a judgement call and keep the build green. You can check out the prompt, action, and past PRs for examples ex. Jules prompt is here: https://github.com/alpeware/datachannel-clj/blob/main/prompt...
Building a custom feed for Bluesky which uses collaborative filtering over the likes data: https://foryou.club

Launched the feed a little over a year ago and it has become the most liked feed.
I've been working on a newish variant of Sudoku called Binku. It combines the traditional Sudoku rules and adds the rules from a game called Binario/Takuzu (with 1-4 as one color and 5-8 as the other color).
A sample puzzle can be found here: https://sudokupad.app/23x300ggzn
It's been well received by the (very kind!) Sudoku/puzzle communities, so I'm working on throwing a nice interface on it that fits the rules a bit better. I've found about five other examples of others doing a variation of this ruleset before in one way or another, and it's been fun trying to see how hard/deep I can get this puzzle to go.
I am working on a research institute for East Africa, https://maiyoinstitute.org/. I want to tackle the dire lack of environmental data, by using 1. low cost hardware 2. Artificial Intelligence 3. Long term horizon. The problem set is huge, but I am focusing on low cost sensors for Air and Water data collection plus bioacoustics for now.

I'm working on turning our statically-typed formula engine -- that we use for Calcapp, our app builder -- into a real hosted solution (as well as a library). I discussed it in July last year (https://news.ycombinator.com/item?id=44702833#44704642) and have been working full-time on the project since the beginning of the year.
I figured "I already have a battle-tested solution, I just need to make it modern and spiffy, build a website for it and see if there's any interest -- in the age of Claude Code, this should be fast work!"
Wrong. Taking an internal library and offering it to others -- complete with documentation and modern tooling -- is an immense project, even with the help of AI agents.
Is there a market for a "formula engine in a box"? I don't know. But I also didn't know whether there would be a market for Calcapp either, and that has supported me working full-time for the past seven years. So I'm willing to take another chance.
I track my learning and schedule repetitions in google sheets. But Google sheets sucks on the phone. So I built a dumb frontend reading off of my (public) google sheet which just has 4 columns for links, title, dates and wait times, plus a formula. Webapp pulls the sheet as csv, renders as color coded lists and a couple charts. Chart shows what's due this week on a 15 week timeline. This is the simplest luddite version I could come up with. I don't have a way to share this with others except sharing the source. Not introducing complexity from auth, storage, managing updates from the app, etc.
Social Maps: a user reviews and ratings service for points-of-interest (e.g. cafes) in OpenStreetMap.
I’ve been trying to reduce and eliminate my reliance of the Big Tech and the lack of user reviews and ratings was always a big pain point for me each time I tried to switch away from Google Maps.
I’ve started building a service where users can write reviews and rate “places” (POIs) in OpenStreetMap database, such as a cafe, a museum, or a shop. It’s a quite straightforward CRUD app with bunch of OpenStreetMap-specific features such as logging in with OpenStreetMap and querying places by their OpenStreetMap metadata.
It’s still in active development but it has good docs, a great API reference (including an OpenAPI spec), a demo app with the entire planet imported and queryable, and an early stage Android SDK.

I made https://poemd.dev/ as an online markdown scratchpad that supports GitHub Flavoured Markdown and stores all data in the URL. This means there are no accounts to work with and everything is basically stored in bookmarks if you choose to.
The persistence model makes documents somewhat sharable, but I do find Open Graph previews to be mixed. In Messenger it renders the whole URL, which is quite long due to encoding, and that kills the conversation view.

Been working on https://searchcode.com/ again which I bought back, albeit as code search tool for LLMs. It solves the “should I use this library” by allowing the LLM to inspect search and analyse it before integration. Can use it to compare multiple repositories before downloading. It comes with a large amount of token savings and can be really useful when wanting to learn about a codebase.
Since it does it anyway I added dossier pages to it as well https://searchcode.com/repo/github.com/rust-lang/rust Which is useful for humans, and shows what the system is creating.
Best part is that I get to use the tools I have built, so https://github.com/boyter/scc and https://github.com/boyter/cs to improve it which benefits anyone using those tools.
I’ve been working on an OSS backend-in-a-box called [aepbase](https://aepbase.io/).
For the past few years, a group of us from Google, Microsoft, GM, IBM, Roblox, Rubrik + more have been working on a design standard for APIs called [AEP](https://www.aep.dev). The goal is twofold: learn from our companies mistakes around APIs and enable better tooling with less configuration.
We’re at a point where AEP-compliant APIs get a resource-oriented CLI, MCP server, full UI, and Terraform provider for near-zero configuration.
Aepbase has been my way to tie the whole ecosystem together. You run a single binary and define the schema for a resource with one API call. Now, you’ve got a full set of CRUD APIs and support for CLI/TF/MCP/UI. After one API call.
It’s a really cool way to tie together all of the work AEP has been doing.
Love to hear HN’s opinions on all of this. We’re still trying to figure out the best way to sell people on AEP.
I am working on a WASM based procedural plant generator:
https://nodes.max-richter.dev https://github.com/jim-fx/nodarium
http://autonoma.ca/calculators/rocket/antimatter/
Given a distance, an allowable time to reach that distance, a payload to send, and an expected exhaust velocity, how would you calculate the time required to convert energy into antimatter fuel and how much antimatter needed to arrive at the destination (starting from the Moon)?
There are a few side calculations, such as the size of the radiator, estimated footprint of the fusion reactor itself, and how much metamaterial is needed. This is to help figure out timelines for a sci-fi novel, so ballpark answers are completely fine.
The calculations yield what appear to be values around the correct order of magnitude. Would be delighted to have insights, comments, and corrections.
I recently switched to developing VST audio plugins and I'm loving it. Already done 3 [0][1][2] and I want to keep doing this if I manage to generate some income from it. I develop them in Typescript and then convert them to C++ with Webview, this way I have a web demo of the plugin that is almost identical to the one you get for the DAW.

Draws from a bunch of sources, MCP-connects to my agents, comes with a browser plugin to invite meeting bots to calls, lets me (and my testers) leave notes on websites which also gets added in.
The goal is to make work as simple as dragging tickets around, and load as many best practices + review clarity into it

A high-throughput multicast Bitcoin transaction distribution system, with a roadmap towards billions of transactions per second.
Features:
- Control channel for block header announcements, operational mechanisms, and network topology automation
- Separate channels for subtree, subtree grouping, and transaction load
- Transaction load sharding by deterministic multicast group membership based on TXID
- Transaction specialization filtering and retransmission both unicast and multicast, to connect edge networks only interested in a portion of the transaction load for whatever reason
- NACK-based retransmission of missed packets via hash chain gap sequence tracking (per sender, per shard) with automated caching endpoint beacon discovery and tiered network distribution
- BGP-AnyCast based transaction ingress
Basically all the topology pieces to scale the actual small-world network for Bitcoin miners or transaction processors; dense at the core, with layered and sharded group distribution towards users at the edges. Right now just site or org-scope multicast in planned, but provisions are being made to extend via MP-BGP eventually.
For BSV Blockchain but could work for the other Bitcoin variants too, if they ever wanted to scale.
I've been iterating on the type system of a somewhat-kooky programming language I'm developing: https://github.com/mkantor/please-lang-prototype
AI basketball community, using computer vision to get highlights and stats http://ballers.gg
Paste Redactor. It redacts Personable Identifiable Information (PII) from your clipboard when you copy and paste text. It uses a custom trained local AI model so that your PII never leaves your device. That is what it does now. Currently working on it to make it work for agents as a privacy protection layer. The idea being that the most powerful AI models live in the cloud but need access to your local files to be useful. We instead want everything to go though a local protection layer before it is sent to the cloud possibly with labels and then reconstructed locally when the cloud sends back its results. Kind of like a Adblocker but for agents and private data instead.

I'm working on a little local first review tool called Review (though I sometimes refer to it as differ since that's it's original name) - you can see screenshots here https://x.com/rhyslikepb/status/2053149881104265599?s=20
The idea was borne out of wanting to use the review tools that you get on existing sites like GitHub, without having to push and start bloating PR lists. You'll be able to leave yourself comments and code suggestions after review, which you can then pull out in a Markdown file to feed back to your coding agent (or anything else for that matter).
I'm also trying to include some optional (very optional) AI extras where you can use your own keys, and then get a tour of what you've changed and a quick overview of the changes.
I am trying to better my understanding of Agentic coding tools and Tool using Agents by building my own, without relying on an Agent that writes said Agent/Harness
I believe writing my own "Toy Harness" is a good way to learn and understand these tools.

I am working on a framework that lets you easily create tools inside the Django Admin - https://djangocontrolroom.com
I've published several panels under this banner already (tools for redis, caches, celery, etc.); I am currently working on a base library layer for tools to inherit from and to make it easier to create new tools.
Essentially, the point of all of this is to make it so that you don't need so many external services; Instead, DCR provides self hosted alternatives. This in turn makes it a lot easier to build and productionalize something using Django.
Reception has been decent so far and I estimate several thousand current adopters (Its hard to estimate based on download numbers alone.) For May I will finalize a common design language, further formalize the plugin system and how it works, and likely release a new panel.

Employee benefit plan analytics. Had a huge dataset long ago as a consultant to the industry and finally vibecoded up a decent frontend. All public data but if you know the data there is a bunch of analytics you can do. Just about to launch and do some marketing in a few weeks, so saw this and thought I'd throw it in!
Closing up work on my modular, hobbyist, analog computer. (Finishing up the manual—the hardware is already a wrap).
Something I can finally enjoy: just playing with it. I tediously wired up a pair of pendulum simulations to drive an XY oscilloscope—got a nice Lissajous curve.
But now I want to double it to four pendulums. Each axis (still just X and Y) to be driven by the sum of a pair of pendulums. With them out of phase, the curves appear to sometimes collapse but then suddenly explode again…
(Love to eventually hook it up to an actual plotter.)
We're working on Webhound - budget controlled long-running deep research. You set a budget and Webhound will use that much in compute/LLM tokens to research your prompt, with built in verification cycles and optional added verification budget. Every claim is cited with evidence and a direct link to the tool calls that produced the claim
The goal is to build a deep research product for actual researchers, since we believe that it is an extremely powerful product that is still nascent but has enormous potential - which we've already seen with some early users.

I have fully implemented mutable torrents (BEP 46) in Transmission. When a torrent is created, you can set it to be "mutable", and you (and you alone) can add files to the torrent, remove them, modify them, or change their filenames. Other members of the swarm will be notified of the new change, and begin downloading that as well (if they use a client with mutable torrent support). For leechers, they can choose whether to allow mutability on a per-torrent basis, and only in the fashion that they prefer. They can even store every change (and seed those) too.
I have the macOS, Windows, cli, and web app working with this feature. I had a bit of a mixup with Gtk, so I don't have a Debian package for it, but it's buildable from source.
https://github.com/NoMoreNicksLeft/transmission
I would appreciate it if anyone wanted to test it. I'd like to think that the feature would be a big deal, even if my implementation of it's kinda crappy.

Still chugging away at my NES rhythm game. Currently, in addition to climbing the content mountain (so, SO much pixel art and music needs to be made) I'm also slowly learning video editing workflows. I was able to put together a brief gameplay trailer this last week:
https://store.steampowered.com/app/4129270/Tactus/
Right this second I'm looking for an alternative to After Effects that runs on Linux systems, as kdenlive has some limitations with its layering implementation. I'll probably give Blender and Godot both a whirl, as I want to get more comfortable with those tools for future projects.
Nice job. I'm assuming this was inspired by Crypt of the Necrodancer? It even has a similar looking "bounce" motion when the main player moves.
https://store.steampowered.com/app/247080/Crypt_of_the_Necro...
Aye, the inspiration is not subtle. Technically it is the latest entry in the "rhythm-based roguelike" genre... which to my knowledge mostly includes CotN and its sequel, Cadence of Hyrule. Both are excellent, and I recommend them highly. Of course I'm unaffiliated, so this is more of a spiritual successor (... demake?) and is its own thing in terms of IP.
I can't overstate just how much I love seeing a NES game developed in 2026. It looks great. I really like the music too.
Have you considered also releasing it to itch.io? (I don't do business with Steam due to DRM and their inaccessible website.)
I would happily purchase a NES ROM file so I could play it on my pitendo (RPi3 in a case that looks like an NES).
I'm not well versed in video editing. That said, the people I know who are tend to use Da Vinci Resolve.
It is indeed also on Itch. I'm planning to release both, along with a physical cartridge at some point. It's a real NES game, so a ROM is included. (No DRM, of course. I'm not even sure how you would achieve DRM on a ROM chip.) I test on an Everdrive N8 Pro. It's a big game, so simpler flashcarts tend to not be able to run it.

I'm slowly but surely working on a first update to my Android app, Tunemark (https://tunemark.app), which I released a while ago. Tunemark lets you add bookmarks to moments in songs so that it is easy to jump back to them. It is really convenient when practicing dancing or music and you need to constantly reset back to specific parts of songs. Unlike most DJ-type apps that could serve similar use cases, Tunemark works with most music apps, including streaming services.
I have new features such as sharing bookmarks and possibly BPM detection planned but also some quality of life changes like better UI scalability for different size screens/split screen use.
Working on a bread recipe community where you can share and iterate on bread recipes. It's out of personal interest to be able to record my bread recipes and thought it might be interesting for others too.
However, I worked on it for the past ~5 years on and off (well, mostly off) and rewrote it too many times. Now finally close to releasing, bought a domain and setting up all the last remaining things.
Instant linux boxes via ssh that suspend on disconnect. Checkout https://shellbox.dev
The idea is to have "real" linux, exposing ipv6, supporting nested virtualization, docker, etc.
Cool, I really like it!
I've been working on Mesaphore, an Excel-like spreadsheet app[0] backed by a Parquet-based file format. The premise is when Excel starts off as the starting point, then over time becomes a data exchange format between systems, and eventually becomes a bottleneck for the system. You still want to provide your users something Excel-like but also want to address the limits of Excel[1].
Majority of code (almost 70%) is generated by Gemini Pro and is extremely ugly. Due to a recent eye injury, I've not been able to code as much as I want, so I'm delegating many things to Gemini. Eventually, as my health improves, I plan to rewrite the entire thing.

I (w/ Claude) have built a framework for writing neural networks in Lean 4 that compiles to StableHLO MLIR and runs on GPU via IREE.
1) “AI harness plugin build system” to help improve reliability of and increase compatibility across the fragmented AI coding harness plugin ecosystem.
https://github.com/jondwillis/jacq
2) Claude code plugin based on some ideas found in https://www.anthropic.com/research/emotion-concepts-function The main idea is to add hooks that inject “baselines” under some conditions to counteract certain “emotions” that can cause subtle misaligned behavior in agents
https://github.com/jondwillis/functional-emotions
3) Final Fantasy XI custom client remaster in Bevy/Rust alongside an MCP integration that aims to allow agents to play autonomously on private servers à la “Claude plays Pokemon”

interesting idea!
Been working on and off on a Spotify recommendation egnine after getting tired of Spotify’s repetitive recommendations.
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, curated by you version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.
It works best if you follow a good amount of artists. Optionally you can get recommendations from artists that belong to playlists you follow or you've created. If you don't follow much or any artists, then you should enable that in order for the service to be useful, as right now that's the only pools of artists the recommendations are based on.

muster and muster-pattern-library. (https://github.com/azide0x37/muster)
an agentic coding scaffold/framework you can reference when building out your next random raspi project. prefer to build around systemd units first; make an idempotent installer script, then put as little as possible custom coding around that.
`impl muster` comes down to: /build out this tool wiring together `patterns` like: C3.dropfolder-trigger; R2.device-binding; C4.lazy-resource-gate
or composite patterns like:
T2R4.device-triggered-conveyor "Bind a physical device event to a bounded ingest job that waits for hot-storage capacity, proves cold-storage capability, stages local work, and hands output to a hot/cold conveyor."
I need to back up a couple hundred DVDs, so with muster I get out:
dvd-ingester T2R4.device-triggered-conveyor
Architecture DVD media becomes ready -> udev rule adds SYSTEMD_WANTS=dvd-rip@%k.service -> systemd runs /opt/dvd-ingester/current/bin/dvd-rip-one /dev/%I --apply -> dvd-rip-one proves DEST_DIR and waits for HOT_DIR capacity -> completed rip moves to HOT_DIR/<run-id> -> dvd-publish-one.timer drains HOT_DIR to DEST_DIR -> publish writes DEST_DIR/.incoming-<run-id> and atomically renames final output
Pipelined; ejects after rip completed. Monitors local disk capacity, retries after NAS comes back online; resumes after random reboot; etc.
I am building Akariq which provides data eSIM data plans to 185+ countries and regions across the world. I am 2-3x cheaper than big brands in the same space. I also prefer local data routing i.e. I don't route traffic from US or EU to Hong Kong, they stay in your country / region.
http://akariq.com/en/
Just curious, I have no idea how eSIM reselling business works: How can you offer 2-3x cheaper prices? Is it because others have very high margins, or because you have a secret optimisation method?
Great question. Cheaper prices come from a mix of focus on customer value primarily. That includes making sure that the eSIM is high quality (low latency, data routing in the region) and also focusing on getting the best eSIM plan to the customer - transparency, better FUP etc. So there's an element of optimisation involved here.
I'm working on JRECC, a Java remotely executing caching compiler.
It's designed to integrate with Maven projects, to bring in the benefits of tools like Gradle and Bazel, where local and remote builds and tests share the same cache, and builds and tests are distributed over many machines. Cache hits greatly speed up large project builds, while also making it more reliable, since you're not potentially getting flaky test failures in your otherwise identical builds.

I have been working for some time on a budget body/facial mocap solution with Unity. Mocap is hard, and what exists is locked behind subscriptions or is just very expensive.
With Unity I'm trying to bundle a bunch of different free, cheap or open source solutions together. For facial, that includes a custom converter from the output of Deadface (based on Mediapipe) with ARKit blendshapes, and also eye movement. For body it's a custom hook to SlimeVR that allows you to mocap with cheap-ish IMU-based DIY trackers, and all that on top of a custom made (not free but open source) physics rig solution that gives you accurate rigid body real time collision, saving on cleanup work.
It's being going really nice despite being an unusual workflow. Hope to release it as a plugin for a in-development sandbox game in the near future. Mocap and animation has been my passion long before i started with tech stuff, and finally I'm able to pursue it.
I’m building a UI design app similar to Figma or Sketch, but with a few differences:
1. Responsive artboards and flex-like layout engine
2. Deep support for design tokens
3. HTML/CSS previews and export
4. Multiplayer AI and human collaboration. Agents can connect to documents and collaborate like any other user.
Built in Swift and cross platform Mac, iPad and iPhone.
I’m designing and building the UI and implementing the underlying features with Codex. So far it’s going surprisingly well.
I'm working on an Arabic-language Electronic Health Records system (moving to Syria in about 2 months and planning to market to clinics there). No current plans to release as Free/Open-Source, but the stack is Elixir/Ash/Phoenix/LiveView/Bootstrap.
While working on it, I realized I should build a small Hex package for authoring and playing demos right in a Phoenix app (it's very easy to author scripts with AI or by hand):

My wife and I continue to work on Uruky, a simpler and cheaper Kagi alternative, based in the EU [1].
Since last month we’ve stabilized the search UI/UX and have 5 search providers you can choose from and sort as you prefer.
We entered May with over 50 paying customers and have recently launched Uruky Site Search [2] (for website owners, this effectively is our own search index and crawler, which we’ll be bringing into Uruky soon as another search provider option)!
Customers really enjoy the simple UI (search doesn’t require JavaScript) and search personalization (from choosing the providers to the domain boosting and exclusion). We also have hashbangs (like "!g", "!d", or “!e”) when something doesn’t quite give you what you’d expect, though.
You can see the main differences between Kagi, DuckDuckGo, Ecosia, etc. and Uruky in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you get a copy of the source code!
Our main challenge right now is outreach because we want to do it ethically, and it’s hard to find communities or places to sponsor which are privacy-focused and don’t require €5k+ deals. Ideas are welcome! We’ve been sponsoring a project per month (Qubes OS, The Tor Project, and Hister so far), with our limited budget of ~$100 / month.
Because of bots and abuse there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a week for free, reach out with your account number and we’ll set that up!
Thanks.

Hey, I'm from the EU and love to see such a project!
One thing I can recommend right off the bat is Reddit - there's many privacy focused subreddits, and also you can share the whole project in EU related subreddits and e.g. r/SideProject.
Would love to try it for a week, this is my account number - 9772263817629091
Keep up the great work!
Thanks for the suggestion! We're trying to avoid anything that's social media (though Reddit is debatable), at least for now.
I've topped up that account number for a week, enjoy (I'd recommend removing it from the post because anyone will be able to use it)!
Working on a tool that lets you author in WordPress as usual (own Docker container, full editor + plugins) but exports the site to static HTML for the public version, so PHP doesn't run in front of readers.

Adding support for the threads/atomics proposal to my Wasm to Go transpiler: https://github.com/ncruces/wasm2go
Since I started it a couple of months ago, it's been used by me to transpile SQLite to Go, and by some other folks to transpile other C, C++, Zig and even Perl libraries to Go.
I continue to write. Unsure the end goal but in my recent dispatch I learned to get out of my way, stop intellectualizing life and let it be.

Read your most recent piece and I like it. Beat generation sort of feel, extemporaneous, haunting in a good way. Keep writing even if only a handful of people read it.
Thank you, much appreciated!
It's been three months now of building Crit - https://crit.md - local first, open source tool for reviewing markdown and code output from your favourite AI agent.
It's inspired by GitHub PR review workflow, only with quick iterations and local.
It's been great! I found some dedicated users, dogfooding it every day with Claude and starting to get more contributions from the little community. We just got accepted into Homebrew core which was my target.
I'm expanding the team features now as I've got a few users keen to get the sharing service deployed in their private networks!
An EU replacement for PagerDuty, focusing on the absolute basics - SSO as the minimum even on free, no AI driven workflows, overviews etc. but may include ML/AI driven insights in future since that’s the way the world seems to be going.

I'm working on https://fdeploy.com
fDeploy is a self-hosted Windows deployment automation tool — a lightweight, on-prem alternative to Octopus Deploy.

Just started working on a book to celebrate the 50th year of our symposium, which is coming up in 5 years. The initial idea is a how-to book, filled with essays from past contributors, but since we only started yesterday - that may change.
I've been going through Nora Sandler's Writing a C Compiler book and writing a compiler in Python. I'm excited to start the chapters on optimization - those seem like the most fun algorithm problems.
I recommend the book. It certainly isn't easy (maybe 3x harder than Crafting Interpreters), but I've learned a ton (eg how to deal with operations on different sizes of types, or the trick of using pseudoregisters to avoid having to figure out registers up front).

I vibe-produced a website for an (earnest?) pastiche of Final Fantasy games (i.e., for a game that does not, and probably never will, exist). I noticed that Nano Banana could generate reasonable facsimiles of Square Enix's promotional render style and ran with it. Next up: faking some gameplay or a few shots from an FMV-style cutscene.

I’m working on a ground-up implementation of RADIUS with everything running on stateless compute. It’s a beast with many problems to solve but I have EAP-TLS, TTLS and PEAP all working. I’d love to connect with folks interested in this kind of thing.
What motivated you to start this and which language did you choose?
Past trauma motivated it.
I was responsible for multiple RADIUS services used by millions of people every day. The existing software is slow to build with, difficult to scale and expensive. I couldn't let it go.
Step one was building the platform to run it on and make it sustainable as a business. Step two is implementing protocols like RADIUS that lack a separated compute/storage model but should really have one.
I chose C# because I know it, and build native single-file executables using AoT.
So you are looking to offer a managed RADIUS server once you've finished building the software?
Maybe. I'm thinking about options but haven't decided on anything yet.
Sort of uncurious about your implementation, but very curious regarding your trauma. I have found a lot of the OSS options for RADIUS suck in specific ways. Never had to scale it however.
The two are linked. Need to change the configuration of a fleet? That's going to be restarting every instance of the process. Update an extension model? Same. Load balance? You'll need one that understand RADIUS or clients will suffer because of incorrect session affinity. Client with dramatically different loads? Better put them on different clusters. Somebody had a power outage? Better have 10x capacity on hot standby for the load.
And on and on.
A stateless compute model with separation between the packet handling and the authentication logic solves pretty-much all of it.
Why RADIUS and not DIAMETER, the successor?
A small, generic Go library for retrying fallible operations with exponential backoff and pluggable jitter strategies. https://github.com/nodivbyzero/try
Working on Marmot https://github.com/maxpert/marmot recently added support for vector index. My local benchmarks show pretty decent QPS with less than GB of RSS on DBpedia dataset.
Interesting part is that I started off implementing a research paper for indexing and performance was not good enough. I ended up tuning things up for my own use-case and ended up with good enough replicatable RAG store.
Main project is a deterministic .NET runtime (https://github.com/Smaug123/WoofWare.PawPrint). Today I upgraded it to net10, which has naturally caused dozens of regressions which Claude is beavering away at.
Side project is my own agent harness, https://github.com/Smaug123/writ , which is being built sandbox-first and with Nix as a first-class citizen. Obviously everyone has to write their own agent harness as a rite of passage.
I'm working on Isola (https://github.com/isola-run/isola), a passion project of mine. It allows you to easily create and control sandboxes for executing untrusted code on any Kubernetes cluster (one helm install). To support some features I wanted (like on demand snapshotting of specific containers' filesystem in a sandbox pod or limiting egress rate from the sandbox I am working on now) I contributed some changes to gVisor. Happy to chat about the design and implementation of such a project if anyone interested!
I'm working on Repple (https://repple.sh)! It's a modern spaced repetition x incremental reading/PDF library app with a few (tasteful!) QOL AI features.
I've been using Anki for 10+ years and love it but always wanted something with a cleaner UX and a reader view. The recent Anki ownership change pushed me to finally make something, and it's seeing some traction :)
Right now I'm focusing on getting the reading and note-taking view to be nice. I used to use Polar Bookshelf (RIP) but that went away, trying to make something better.
The flashcard side also has a REST API btw!
Currently working on `imgsrv` which is basically a container registry but it holds disk images. Enforces versioning, allows attaching multiple formats for a single release, prioritizes immutability, etc. Intended to build fully automated image release pipelines. I use a PXE setup for my homelab, so having a common place to manage image release lifecycle is helpful.
Right now I intend to make it compatible with Incus as a remote. So it's just a matter of adding it as remote and then you can consume all of your versioned images.

I'm making a surf forecasting site a la surfline.com, I started mostly to have an API to use for my tidbyt, but I figured I might as well make it a full thing and built my own features! It's on quickswell.com but it's only Socal at this time (fewer spots to compute)
Diving deeper into woodworking and knocking out a few cabinetry/storage projects with the work-in-progress up at at https://shopspec.io
I’m building a small map application that allows me/friends/family to explore data overlays about morel mushrooms phenology and habitat (ground temp/moisture/terrain/aspect/tree species/etc) in our area. There’s some lightweight forecasting and timing models to help guess at near-term fruiting. I had a big push about a mouth ago to tighten things up, and initial experiences in the field this year have been very promising.
I’ll keep chipping away at it this year, and probably expand beyond morels to other seasonal natural phenomena that my people enjoy like smelt/salmon run, wildflower blooms, etc.
I'm continuing to focus on ways to set strong code quality guardrails in an era where most code is not handwritten.
The result is http://getcaliper.dev.
It has a number of mechanisms that help substantially:
1. It can extract deterministic quality checks from your CLAUDE.md text; these checks then get executed after every agent turn.
2. It performs a lightweight ai-powered review at every commit; feedback goes directly to the agent, which can then make corrections.
3. It performs a more 'traditional' deep AI review at merge, or on-demand.
Free to use, just bring your own API key. Any and all feedback is welcome!
Writing my own programming language eyg.run that for a long time had no syntax. I worked on a structural editor for a long time and this weekend I finally documented the sneaky text syntax that did exist for testing. So the structural editor I'm not sure about the future. The language is still fun to write and use tho.
I'm working on https://vtxmacro.com, a free and fully autonomous LLM trading platform. Basically have any model you want trade for you. Right now I support ~860 models across 16 providers (including OpenRouter), plus Local AI and OpenAI Compatible endpoints.
The bot settings (system prompt and user prompt, temperature, reasoning, etc.) are 100% transparent and customizable, and all users can view and copy anyone else's settings from the leaderboard. The goal is to build the best trading bots possible by seeing what works.
You can run a bot on Gemini 4 31B with a free tier Google AI Studio account (I'm running 5 bots on it myself). Or just run Gemma 4 26B on your PC if you have the GPU for it. I'm running 5 on my 5090, so I'm trading with 10 bots total.
The platform is connected to Hyperliquid and you can trace all the trades on the blockchain from the user's Analytics page (always public).
The way it works is you set a loop interval (default 1 minute) and the model receives the candles, market stats, indicators, account balance, current positions and so on and decides Buy, Sell, or Hold and how many units.
It's still experimental but I have already processed 1m+ prompts, 10k+ trades, and almost $1m in volume since January 2026. I have around 15 bots running right now, you can check their PnL on the leaderboard (public). I've made a lot of changes in the last few weeks so most recent either 24h or 7d results are the most relevant. The model you use is super important (Gemma 4 31B so far is the best value I found, better than Gemini 3 Flash and you can run it for free) and also the coin you choose is important too. Preferably, you want something that's trending. My friend's bot did well with ZEC and VVV this week.
Right now I'm working on improving reliability (I bought a Japanese VPS to run my own HL node), and this weekend I moved the app from Render to my own DC VPS for 10x+ cheaper and 1000x more bandwidth (25 TB instead of 25 GB, seriously if you're using Render and want cheaper infra look into buying your own VPS).
I'm also implementing CLI/MCP for OpenClaw support. And next is an automatic screener that will use LLMs to pick the most promising cryptos to trade (since I noticed this has a huge effect on PnL).
If you have questions, let me know, the Trade page has my Telegram group link.
I’m working on Beanback, my side project SaaS app for ‘effortless digital loyalty for cafes’.
It replaces paper stamp cards with Apple Wallet passes (Google Wallet coming soon) without the need for customers to download an app or signup. It’s still very work-in-progress (forgive the landing page) but I’m enjoying using Ruby on Rails. Please let me know your thoughts!
https://beanback.space/
Still working on ghidra-delinker-extension, trying to wrap up the OMF object file exporter at the moment. Then I'd like to implement generation of debugging symbols (at least DWARF and CodeView, maybe STABS and CTF), although lately I've received a PR for PowerPC and an issue for delinking shared objects.
I'm also thinking about writing the Necronomicon of delinking at some point. The extension keeps spreading by word of mouth and there's only so much UX improvements I can do, for something that requires throwing everything you've learned in CS 101 into the trashcan before you can "get" it.
For occasions like birthdays or Christmas where people want to give you gifts, I have always wanted to ask them to make donations to charities of my choosing instead. So I built an app to enable this: http://donateyourgift.com/ It is very simple but I didn't find anything quite singly-focused like it, so I built it just to scratch my own itch.
I have been experimenting on using AI for hardware development. I showed some experiments on HN a couple of weeks ago (https://news.ycombinator.com/item?id=47801255). I am now trying to make my approach a little bit more comprehensive and structured, instead of several disjoint MCP servers, a single platform that connects lab instruments to AI assistants: https://teasel.tools/
As a demo, I repaired an old Philips PM5190 function generator (about 40 years old) and connected it to Claude Code. Lots of fun. Going to post a follow up video the next couple of days.
The other day I got into some pretty weird territory with Claude, trying to map out what an immortal ASCII cat would look like. Basically an autonomous Tamagotchi.
The idea was to create a quine that runs forever on something like Akash network with its own crypto treasury to support and pay it's bills and try to replicate. It would then talk to an LLM for support and actions on what to do to stay alive.

I am working on mesh (https://growmesh.io) I started working on the topic of human development two years ago and I dived into the topic of how humans have been trained, manipulated, educated or brainwashed. My central idea which I am investigating is that whenever a person is interacting a highly tuneable ML model such as the X/Fb/TikTok feed or chat interfaces with LLMS, does the thinking and development of the human happens more times or less due to the new experience.
After having it on my TODO list for a long time, I've installed EndeavourOS on another m.2 drive on my desktop. With the advancements in gaming support on Linux over the last few years, over 80% of my daily tasks, work, and games are well-supported by Linux. I've been using Linux in VirtualBox or WSL for many years, but it's been a long time since I've ran Linux directly on hardware. I'm excited!
I've been working on a AI app to replace Claude Desktop and Mobile for personal use.
The main goals are to own my data (memories, artifacts, chats), be able to switch AI providers at any point (if one is down or I want to try a new model), have the same experience between desktop and mobile especially when it comes to working remotely on code.
A bigger vision is to offer everyone a alternative to Claude and ChatGPT they can own just like OpenClaw but with a great app experience.
I hope to have the first beta published by the end of next week.

I am working on Desiderata (https://github.com/github-of-NMI/Desiderata).
An LLM benchmark for open-weight models only, with secret questions.
The questions are asked multiple times to calculate a consistency score.

I’m working on bomberman in ClojureScript, using no libraries, and making sure I write every line myself, it feels good to go slowly for a change having used a lot of LLMs in the past year.
I’m working on what I call a Software Delegate [0].
You delegate a task or GitHub issue to it and it uses AI coding agents and developer tools to write the code, run checks, read failures, fix problems, and iterate until the result is good, then comes back with a pull request. It does everything a human dev would do, fully automated.

I’m working on Recoil, memory safe, compiled static language (yeah, I know, everybody’s doing it) with Rebol syntax and built-in candies like parsing, finite state machine and rich syntax (that’s given, because of Rebol).

A small launcher for Claude Code, to make switching between different providers and configurations easier:
https://ccode.kronis.dev/
For example, if I downgrade from Max to Pro I'd still be able to use the subscription, but also run sessions with other models (less expensive/local) as desired:
Source available, pre-built binaries on itch.io, pay-what-you-want with a minimum price of 0 USD, probably get it for free first if interested in taking a look.
I finally got around to signing app for Mac, which is what this post originally was about: https://news.ycombinator.com/item?id=48075366 (the new versions will be out soon)
Also thinking that I might make it an Anthropic API --> OpenAI API proxy that allows talking to providers that don't support the Anthropic API directly, alongside allowing switching models dynamically during a session (Claude Code wouldn't even have to know about it, it'd just send requests to a local endpoint and the proxy would do the rest).
Early on, but Go is lovely to work with, mdBook is great for getting a site off the ground and I'm really surprised that more people don't use Itch.io for distributing software (or the pay-what-you-want model in general), it's dead simple!
Trying to get my product (desktop application) to the state of minimal sellable version (according to my quality level expectations).

I'm not just talking GPS coordinates, but speed, direction, motion detection, precise timing between waypoints, being able to play these trips forward and backward, step by step, etc. I'm talking time-travel debugging for GPS applications.
It's early days. I'm not even sure it's possible.
It seems doable and cool to me. Glad your working on it!

I'm learning about inference by running vLLM on a k8s cluster (EKS), building a gateway to keep a <2s TTFT SLO.
Most recent ha-ha moment: I kept wondering if it was normal that my cluster was only able to process 4 requests per second per vLLM engine (just seemed really low to me).
I realized a better metric is in-flight requests... Each engine is processing 70 requests at any given time, streaming tokens for over 30s.

A few days back, a book on FreeBSD Driver Development was posted here [0], and everyone assumed a) it's LLM slop and b) a terrible introduction to the topics covered.
I scanned a couple of chapters and realised it likely wasn't LLM generated, it just needed an edit. The intro to C is a hard and weird intro, but then driver development in FreeBSD is hard and weird and people who aren't prepared to get through such intros probably aren't going to get through the rest of it.
Being the contrarian, I've started going through it. I was involved on the periphery of the FreeBSD project ~25 years ago, went to conferences, ran a BSDUG in my hometown, and so on. And I realised I've missed systems programming and FreeBSD itself a little, and in recent years became a little sentimental.
What I've discovered so far in the first few chapters:
1. I miss FreeBSD. And it's weird my muscle memory kicks in and am surprised in a lovely way to find familiar things like /etc/rc.conf work the way I remember them.
2. This is not AI slop. There are issues that I can blame on him not using the same platforms I am (if you're on Apple Silicon, just use UTM and the aarch64 ISO - don't use the VirtualBox config he suggests, as an early example), but as somebody who sees a lot of AI generated content in my day job - this isn't it
3. I have got excited about coding again for the first time in a while.
So, this is my hobby for a while. Go back to where I started, get into low-level systems programming again, I have some ideas on some hardware I want to help out on... it's different to a lot of what I've been working on for the last decade or so, but that excites me.

I've been vibecoding* a calendar-based personal note-taking thingy: https://github.com/cu/doneski
The idea is that each morning, you click the "New Day" button, and your Todo list along with other notes carry forward from the previous day to the new one. When you accomplish something, you add it to the Done section. Other sections can be added as needed. I have been using a text editor and/or shell script for this purpose for about a decade, but have been inspired to make it into an app now that I can delegate the boring bits of app development. It is not quite done yet, but it's getting close to being usable.
(* To the inevitable downvoters, this is in part an experiment to get familiar with what SOTA LLMs can handle. With the intent of comparing it to local LLMs once I get my Strix Halo set up as a coding assistant. I only code as a hobby currently, and have too many other hobbies, and this app wouldn't exist without something else doing the heavy lifting. That said, this is a pretty low-stakes application and I don't commit any code that I haven't reviewed and don't understand.)

There is a little video demo here (but bear in mind that everything is temp graphics) https://hakon.gylterud.net/diary/2026-05.html#2026-05-02
Working on a native non JS Http client similar to Insomnia.
Working on a framework for factory management systems.
Working on a Platform That hosts Open Source software & Gives users Enterprise-Level AI Assistants & Support to challenge Saas Software (Just a MVP right now!!)
I just hate the Saas Scene today - even a small productivity app is worth $10-$15 / month . When you couple that with a bunch of apps that you use , you spend hundred of dollars in hard-earned Cash .
The Open Source Community is Amazing on Some fronts , but then enterprise & non-technical users can't use them without a layer of Support , Hosting & Setup Assistance .
We want to be the delivery layer between the Current Open-Source Community & Saas users .
Got a lot of ideas to work on it , but decided to build out a small version right now and launch it !!
Playing Doom.
I am working https://vibu.app which is free digital voucher
and for fun, I am building yet another programming language!
getting my 1-person business to 2M ARR[0]
the requirements for growth keep changing plus all the AI noise means that the playbook changes regularly. staying on top of the state of the market while improving/maintaining the product and understanding our icp + exploring new verticals is a tricky (but fun) task to manage!

I got let go back in March, and since I've pivoted into building a game. In the 3 weeks leading up to unemployment, I had gotten way more into an old GBA game I used to play back in the day, Harvest Moon Friends of Mineral Town. The (remake of the) game that inspired Eric Barone to make Stardew Valley. I was bumping into the same in-game limitations of the cartridge and platform that always made me want more from it, (and while Stardew Valley was nice, it never fully scratched that itch) and as I found myself unemployed, I found the mental space to start building.
The game is going to be a farming tycoon/city builder game where you can buy farm stands and advertise to sell your goods. As your operation grows, you grow the local economy and people move to the town turning it into a city, opening up the chance to sell at farmer's markets or supermarkets. As the city grows you'll have to buy/sell land with the city and work with the mayor to plan where the city should claim new land for you to purchase so you can stay on the outskirts with healthy soil (or in the endgame, run for mayor and manage the growth of the city yourself, a la Sim City/Cities/Frostpunk)
I chose Love2D as my engine so I can use the relative simplicity of 2d art in 2.5D pseudo-3D instead of 3d modeling. The world space is a 3d euclidian grid of cells wrapped around a horizontal cylinder on the x axis. The view space is perpendicular to the side of the cylinder, giving us a natural horizon at the vertex of the cylinder on screen. The world space coordinates are expressed in terms of the polar coordinates of the cylinder, giving natural rise to radius as altitude, angle theta as latitude, and x axis as longitude. All the world math can be calculated using the trigonometry of the unit circle, and converted to 3d Cartesian coordinates before converting them to screenspace coordinates. I can use regular flat plans and elevations for the texutures of building faces, and render them upon linearly transformed quad polygons. Maybe I can also do some screenspace displacement a al Crimson Desert at the finish line to give buildings window sills and ledges when you see down a side of one.
I am doing the development without LLMS as much as possible so I retain a good grasp on Logic, Language, and Math. I have been having a lot of fun digging back into these multivariable calculus and linear algebra concepts I thought were beyond me (because of some autobiographical amnesia issues I deal with) to discover that no wait, I was taught these concepts in high school and was quite comfortable applying them. All the development is done on my own private, secured git instance on my homelab server and I can pull down the latest revision to my iphone to show off, it's been really cool. Kind of a pita to find a good git app on iPhone that allows custom git servers with ports though.
screenshot of a very early hello world, before I made the mental connection between wrapping a 2d cartesian plane around a cylinder and actual 3d cylindrical polar coordinates, which is why the shapes just sit over the world rather than extending from it, I hadn't yet conceived of the radius of the cylinder being altitude: https://fucci.dev/assets/helloworldspace.png
I am writing synthetic aperture sonar/radar simulator and image formation code from scratch.

Too many codes or old or gate kept behind proprietary walls. Many are old and don't use the newest acceleration techniquea to make the simulation fast. Additionally, none of them scale using aws. I want SAS/SAR image to be easy to generate for anyone.
I just started on an open source and open weight supervised learning model to recognize japanese kanji characters drawn on the screen.
I have a working prototype written in Julia which is a very simple neural network. The input is in vector format so traditional convolutional neural networks don’t work out of the box but I swapped the convolution layer with a path simplification algorithm and it worked extremely well. Like 20 samples per character (from a set of only 5 hiragana during prototype phase) was enough to get 100% accuracy in a test collection of 5 samples per character after only 30 iterations of training.
I plan an working with free and open data, which I don‘t think exists for japanese kanji characters (at least not in vector format; KanjiVG only has one sample per character and I need dozens) so I also build a crowdsourcing web site to collect data from random people on the internet.
I am planning to run some more experiments with my prototype model before I release the crowdsourcing web page to an actual server though.

Another thing I’m working on: homemade linen.
Right now I just germinated a 4x8 bed with flax for fiber. The plan is to grow it for 100 days or so and then harvest, dry, ret, dry, and spin. I need a lot more to do anything serious, but I think it’d be awesome to have a scarf that I made with linen I grew and harvested myself
