Ever since I read this https://paulbupejr.com/developing-the-optigap-sensor-system/ I've wanted to build a system that takes in a shape and adds bends and fiber routing so you can dynamically create readable objects. I was initially imagining wanting to add the bending points manually but I'm not so sure that's the best practice and I may want to think of a heuristic for good vs bad bend points before even considering the UI.

I also bought some cheap gloves from harbor freight and used a needle to route fiber through each finger to make a simple power glove like thing which I think I can connect to arm arm to make a cool robot game. I think of the two I am more excited for the first but its much more work than the second and my day job is getting more exciting than I would like so by the end of the month I'll have had to pick one to finish.

I am working on Cangjie Workbook. I am trying to create the best in class tool for learning Cangjie. It's a Chinese input method based on decomposing characters into sub parts (not necessarily related to how they are written). It has a high learning curve, but it is a lot of fun to type with and helps you remember characters. It is a tool that I use myself. I already have a couple of users that have been giving me feedback. You can use a subset for free and without any login credentials. The complete product is available for a small monthly fee. Any feedback is welcome!

I'm working a new Fantasy Football league/format that is category-based (like hockey/baseball) in an attempt to make games more "watchable". The problem with traditional Fantasy Football, is that half of the game (defence) is ignored, while not very economically-valuable positions, like RB and TE, are elevated far past their real world relevance. This new system is attempt to fix both problems!

A new spec, TPX, which is meant to enable building SaaS where the user brings their own inference:

https://tokenpony.dev/

It has a few potentially interesting side effects:

- enterprises can plug their preferred LLM into the SaaS they use.

- self hosters can extend their rigs into the web.

- simple SaaS products can offer LLM integrations without their entire pricing model being upended by LLM hosting and infrastructure.

- we can all live like Ender in Xenocide and have a personal AI that has context on everything we are doing.

- have a no op provider for people who are anti llm.

Still working away on a completely offline meeting document generator that works on generic laptops with no GPU (https://whistle-enterprise.com). A new release coming very soon focusing on getting clearer audio which in turn makes the transcription and end document generated more accurate.

Inbetween that I've been working on a "software house" (don't know how else to describe it). Pretty much codex/claude running on a VPS with a web interface and the ability to actually build and publish software / webapps etc.

It came from me sitting on the train on the way home and I had an idea pop into my head for a pebble watch app, I wanted to build it and test it there and then as I still had about 45 mins left. I know you can run codex against git repos in the cloud but I didn't want to faff with that (and last I remember the allowances for this were much less generous). It's been really fun, probably many things like this out there but it works exactly how I want it to. I plan to open source it once I've tidied things up a bit more.

I’m building an image sharing site (just for me and a couple of friends) that tries to emulate the old days of Flickr and Instagram. Chronological feed, no recommendation algorithm, no reels, no ads, etc. Knowing that it’ll never be open to registration or “real” users takes all the pressure and expectation away and it’s just been fun to work on.

An overhaul of my original PlayStation bare-metal programming tutorial repo: https://github.com/spicyjpeg/ps1-bare-metal

It was never really meant to be an SDK of sorts that other PS1 homebrew projects would pull as a submodule and depend on, but since it more or less became one I am likely going to split off the examples from the "core" (headers, CMake build scripts and tools). I have also been asked to add more examples, particularly on how to play sounds through the SPU and access the CD-ROM drive, and may cover I/O on some PS1-based arcade systems in the future.


👤 t4nner
emira, a tiling-scrolling WM for macOS: https://github.com/lightningboltemoji/emira

I know there are lots of options in this space, but I wanted to experiment with a new approach: a compositor overlay. During transitions (like scrolling on focus, moving a window, etc.) an overlay pops up and uses _screenshots_ of windows for animating while the real windows move below. Once in place, the cover dissolves out. It's not perfect, but this makes it _feel_ much closer to native.

iI am working on a synth engine (music synthesizer) in Python and C++ not a developer; music producer, classical pianist, and occasional NI Reaktor programmer.

It creates sound from math expressions which were inspired by the Desmos graphing calculator.

The sounds are mainly of the FM/DX7 taste.

i can't decide whether to show my progress on video by hiding or showing the expressions LLM(s) and myself "discovered".

It sometimes sounds extremely musical and sometimes very dirty and experimental, what's normal for frequency modulation.

Please help me decide: show all and open source or continue working on it and pitch it to some big names. ;-) I have the feeling it has strong potential for prototyping, as well as taking the role of a keyboard engine. It is completely viable to manipulation via AI because of its concept.

It runs nicely on an M4 Mac mini with 256 voices of polyphony and has a very high level of expressivity mainly via half-pedaling (sustain pedal).

Velocity, 8 macro knobs, no filters, no fx, ADSR envelope. A web interface and additionally CLI.


👤 vmg12
I made a site https://snack.game where people can upload and share multiplayer games.

It uses webtransport instead of websockets for the networking transport so the games feel a lot better than normal web based multiplayer games. I'm surprised more people aren't using webtransport given it's supported now by all major browsers.

I'm working on https://www.amika.dev/, which lets you put sandboxed agents on cloud VMs and then message them over the internet.

It's for agent + human devboxes, for chatting with coding agents from the web, or automating them with an API. Thing like Claude Code web, but any agent and you directly control the VM, too.

We're working to make amika.dev work on any computer, homelab, or K8S cluster. For tech folks, I describe it kinda like if Tailscale and Firecracker had a baby.

I am working on a discussion board for HN’s Who is hiring.

Too many times I have been burned by applying to scam listings or people who are just to self-promote and use people who want a job as a marketing channel (looking at you BetterStack, fu in particular).

I want people to be able to discuss and flag companies which are lying or just a waste of time, yet HN refuses to do anything about it and doesn’t allow threads as discussions and removes comments.

Hit me up if you want on the beta testers lists, already got a couple of people.

I got laid off at the end of April and have been building my own personal dream tool since, it's a skeuomorphic carpentry simulator with an agent MCP. You start with real wood specs and a shop full of miter saws, router tables, table saws and the like. Think of it like Sketchup but no extruding rectangles.

It's been really fun to build with. Agents can create parametric procedures so e.g. stick framing becomes a simple function call for the next agent, building a flywheel. There is full agent-human parity in every surface, so there is a human UI for the procedures too.

Every operation is yaml, so agents pick it up pretty quickly. Agents can also file feature requests when they reach for a tool that doesn't exist. You can export to 3d printing files, video walk-through, step files, get a BOM and a cut plan, view your project in life-size with AR. There is a notion-like interface for authoring build guides... a lot going on. If you're a woodworker/software engineer you might enjoy it.

You can add the MCP to your agent of choice, send a picture, description, sketch or whatever; say "build this with Sawdust"

Working with agents generates a lot of markdown input and output. So I'm working on viva, a tool to help author and review docs.

You tell it what kind of doc you want, attach any necessary links/files/repo paths/etc, then it asks you clarifying questions until it has the data it needs. Then it authors a doc and give you a review interface. You can approve, request more info, request changes, make direct edits, etc. Then submit and makes edits until and represents until you approve all sections.

I've been slowly building [MiserablyUnemployed.com](https://miserablyunemployed.com/) for the last four or five months.

It pulls jobs from tens of thousands of company HR pages, and only keeps them for seven days (unless it sees that the job has been filled). No reposts. Only fresh jobs.

Besides that it has a resume builder, matching system, application assistance via an extension, job tracking software, and an interview preparation helper. It turned into some fairly complex software that I ended up learning a lot from!

If any of you try it, let me know what you think.

I have two personal projects at the moment.

First, https://agency.nu/ a personal agent platform for people who aren’t necessarily developers, but still want to connect multiple Gmail, Calendar, and other accounts and automate workflows across them. Spent a lot of time making the interaction easy and natural, so it supports chat, realtime voice and telegram.

Second, https://vinarium.one/ something I primarily built for myself to keep track of the wines in my wine fridge, when to drink them, and what pairs well with a particular dish.

Both are very much scratching my own itch, but I’m curious if either resonates with anyone else here.


👤 yellowapple
I've been resuming work on a Zig library for developing N64 homebrew¹. Previous milestone was getting a framebuffer onto the screen, and after achieving that I took an overly-long break.

Current goal, which I've been working on for a bit more than a week now, is to add support for controlling the RDP (the part of the N64's GPU that actually does all the rasterization), such that programs can actually draw triangles. I'd already implemented the control registers, so the current work is defining all the RDP commands, along with documenting what they do and how to use them — which means that I need to fully understand what they do and how to use them, and that's been a fun rabbit hole to explore.

I'm currently about halfway to two-thirds of the way through defining packed structs for all the RDP commands, then the plan is to build a CommandList struct with methods to build RDP command lists and validate that they make sense (make sure all the triangle/rectangle rendering commands have all their subcommands in the right order, make sure you ain't calling them without there being a framebuffer defined as the rendering target, make sure the needed synchronization commands are in place where needed, etc.). Then that should hopefully be enough for Zig64 to draw its first triangle :)

More things than I meant to, but one's live and three are landing soon. I quit someone else's work a little while back, spent some time building a game that I'll get back too to the extent I can support myself, and then started a things-I-want-and-others-might-want-too studio.

https://sponder.app (Live) - an RSS and podcast mutator. Filter feeds for what you want, merge, time-delay, and drip articles on a cadence (I like to start from feeds' beginnings). For podcasts, detect similar metadata to previous releases so you can skip reruns.

https://tellmeapenguin.com (Close! Come help test it) - Endless mad libs about whatever you want, and if it's a good story, you can keep writing more chapters. The kiddos love it, and you can share back and forth with grandparents and whatnot to keep sillily in touch.

https://nounogram.com/ (Web is live, apps soon) - Hybrid nonogram and crossword puzzles. Shade the grid to find the layout, then add the words where they fit. I built it to make the kiddo practice handwriting, and then it was more fun than I expected.

https://getyarnt.com (Free until I ship the Stripe integration) - A task tracker that's actively hostile towards you having tasks. Started as a joke, but I'm using it to track my own stuff and really enjoying it. If you have a manager who likes assigning you work, tell them to get Yarnt!

All of it's on https://hahamoment.dev/ in the likely event you don't need any of this but do want to turn on a light.

I tried to build something similar ~10 years ago in the form of a more interactive music game, but felt like it wasn't actually that helpful for intermediate and advanced students. So this time I'm doing it in collaboration with actual music teachers and building a tool that actually helps me learn. I'd say 90% of my flute practice is done using it at this point, and I'm in the process of taking on the first arms length users in a closed beta.

Been going a while, working to shift into a verification layer on existing static scanners rather than a standalone product: https://rsolv.dev takes a highly opinionated TDD approach to _proving_ (or disproving!) scanner-indicated codebase vulnerabilities and writing red tests against the desired secure behavior, so that customers can trust that they're not just making code mutations without cause, and that the shipped fixes actually work, and that there's regression protection in their suite.

Aside from that, I've been getting into building hyper-local services around public data; it feels really rewarding and relatable to invest more locally!

Already up and running: https://hailpass.com/?ref=HAILHN9 (ref code there knocks $10 off the season price) as a "season pass" for latlong/street address level-targeted hail notifications, built specifically for damaging-size hail (not just _any_ hail) on the Colorado front range. Email is free, texts are on the season pass model.

I work on a suite of open source public transit software projects, collectively called OneBusAway (or OBA). The software is used by millions of transit riders every day around the world, including in New York City, the Seattle area, San Diego, and Washington, D.C.

Through the non-profit that collectively owns OBA, I've been working on a managed services offering to help transit agencies adopt the software, which has historically been beloved by users, but a real pain to set up and maintain. The software, cleverly named OBA Cloud, turns what used to require a month-long engagement with a transit consulting firm into a 15 minute, wizard-driven process.

The best part is that since all of the software is free and open source, a transit agency that decides they love OBA but wants to be locked back into an expensive contract can always ask a consulting firm to run the software for them.

Since last month[1], we've added a number of great new features to OBA Cloud, like broadcasting critical alerts to all riders in the system via push notification, and support for Live Activities on iOS.

We're hosting four new public transit systems over last month, and are continuing to make terrific strides on our other marquee projects:

The iOS app update went live, and our riders are generally loving it: https://apps.apple.com/us/app/onebusaway/id329380089

The new Android app maintainer is gearing up to release the biggest new version of the app in a decade: https://github.com/onebusaway/onebusaway-android/

Our GSoC interns are continuing to do amazing work on their projects, including the next generation OBA API server, Maglev: https://github.com/onebusaway/maglev

We're always looking for more folks to contribute to the project, across a variety of disciplines (ie not just engineers!): https://ossvolunteers.com/organizations/open-transit-softwar...

Recently bought a Sovol SV08 printer. It comes with open source binaries, but there is no source code. Turns out they are a known to be violating the GPL. Looks like it can be rebuilt from other sources, so I have started to put together a clean implementation using Yocto. It will be possible to add support for similar 3D printers.

I bought that printer in order to print parts for two other projects: a baby monitor (security camera) and a hat-mounted teleprompter monocle. Both using COTS part and running Yocto-based open source images. All affordable products in both of those sectors are completely untrustworthy or otherwise unsuitable for my requirements, since one of which is total replacement of the firmware with my own custom versions.

In my day job, I am a principle embedded engineer consultant working on distributed embedded systems, so all of the above software will be relatively easy.

The mechanical work will be the most challenging, as I presently only use OpenSCAD. I would entertain suggestions for alternative open source CAD solutions, but I hope to recruit a ME (or two!) to help drive that portion of the work to completion.

I'm working on https://wireplug.org:

wireplug lets you create mesh VPNs using standard WireGuard. Your wg config files stay almost the same, except you no longer have to specify an `Endpoint` for your peers. Instead, wireplug detects all your possible endpoints (including LAN) and coordinates them with your peers for you. It handles NAT traversal and works with the in-kernel WireGuard driver on Linux and OpenBSD. This lets you keep managing your own keys and network topology, while also maintaining connectivity when moving between networks.

Currently working on improving NAT traversal by adding support for PCP and NAT-PMP.

My wife and I are working on a math/science/CS-inspired jewelry business. We try to create pieces that stand on their own aesthetically but have a hidden meaning.

We currently have two styles: lambda calculus based pieces (we depict the lambda/Tromp diagram) where we have Y-Combinator earrings (well, strictly speaking they are one beta reduction away from Y-combinator. Aesthetic oblige) and a pendant depicting a lambda expression computing Graham's number. The other style is quantum computing circuits, based on quantum computing research my brother (a physics professor) is doing: a pendant that is actually a non-local controlled-NOT gate. I wrote a tiny DSL to describe the jewelry pieces, and an interpreter to produce CAD files. We then either 3D print them or have them produced by lost-wax.

We are 200% out of our comfort zone (and love it): I know nothing of front end dev, payments, or anything like that. The diamond district in New York is a neighborhood we normally actively avoid, but if you are forced to go there it is fascinating (people examining diamonds on the corner of the street, others in fur coats in summer straight out of a mafia movie...), and especial marketing. Jewelry is a completely saturated business (luckily we are not doing this to pay the rent); we think we have a unique angle, but we are still figuring out the target audience (if there is one), how to advertise, etc.

Any ideas on marketing are welcome.

Work: Security engineering focused on securing authnz at hyperscale in our new agentic reality. What interests me? Agentic engineering, vulnerability discovery at massive scale. Vulnerability remediation at massive scale. Bounding agent non-determinism.

Personal: Local models. Agent harnesses. Track cars, turning wrenches.

Had agents build recently:

- Photo catalog app with all 100K photos in my library described by a local 9B parameter model (it is absolutely amazing and my favorite personal project in terms of genuien impact)

- Generic RAG layer (vector embedding + FTS in SQLite with RRF and document ingestiation layers for 1-2GB knowledge bases to power agent context for stuff I am interested in, neuroscience and philosophy is where I spend time on this right now, and basically every AI research paper publicly available to help agents tinker with local models). This is especially useful for local models, but it even helps frontier models because they can freely churn through without a bunch of web calls and such when you are on a topic thread or research.

- Qwen 3.6 35B A3B clean-up proxy, achieving a clean thinking + tool calling A3B that I can leave running for 24+ hours. This particular model gets stuck in long reasoning chains and needs encouragement to get on with it, especially on context tasks. It actually reasons well but then starts second guessing and loops. Built a deterministic framework to inspect its thinking and make it wrap its thinking up if it gets stuck and also to trigger calls to external models and inject solutions to problems when it gets stuck. The agent sees the solution injected from a remote model like it is its own thinking, kind of a subconscious it has no idea about. Metacognition in models, it is wild.

DSV4->GLM->Kimi is the "phone a friend" external brain pathing I built. As far as I know no one has shared all of the bugs I have 'fixed' in my project and gotten local Qwen A3B this reliable.

I used to teach C to students many years ago, and with agents it's becoming a niche craft. C is still both an important and fun language to use, and I've been very slowly making a C language course to let beginners learn a bit about the language and practice writing simple code with no AI: https://c-course.com

A work in progress, and will stay so for much longer, I guess.

I'm working on Eland (Extensible Layered Algorithm for Network Drawing), a graph layout library strongly inspired by Elk, but a complete reimplementation.

The reason I need a complete reimplementation is that existing graph layout libraries tend to be black boxes that you can't really fiddle with. If you want to tweak part of the algorithm, you have to fork it or write your own. With Eland, you can replace individual steps with your own implementation while keeping the rest of the algorithm unchanged. To ensure validity of the various steps, I've introduced contracts where every step specifies what properties it requires from the graph, which properties it promises to add, and which it invalidates, which I think is pretty cool.

The reason I need all of this is that I'm working on a system to display and browse through data lineage graphs. I've noticed through experience that existing graph layout libraries don't do quite what I need, so I ended up building my own.

I’m working on PhotoFig: https://photofig.com, a recently launched product-photo editor for online sellers who need to clean up hundreds of images.

It was inspired by my wife having to carefully mask product photos for her online shop. Existing tools could remove backgrounds automatically, but didn’t give her enough control when the result needed correcting. So masking is a first-class feature, with SAM-assisted selection and a precise manual brush.

The backend and storage are self-hosted on hardware I own. Along the way I’ve had to solve some interesting infrastructure problems, including writing a Kubernetes operator that bin-packs GPU workloads across workers. I’m planning a technical write-up on the architecture.

I've continued working on my game project, Vestiges, which is a 2D narrative strategy rogue-like made in Godot.

I'd hoped to have a more meaningful update from when I first mentioned this project last month (https://news.ycombinator.com/item?id=48884984). But I've felt discouraged much of the time since then and haven't worked on it as much as I'd intended.

As was recommended to me by guiambros last month, I started the process of setting up Vestiges on Steam, but that's still in progress (currently, my identity is being verified). I also set-up at micro.blog (https://ksaun.micro.blog/) and (https://mastodon.social/@ksaun), but haven't posted anything yet.

I bought a Linux laptop for this project (I was working on a 2020 Surface Book 3). I had used and liked Unix in the 1990s, but not much since then. The video game industry being so Windows-centric, I'd stuck with that OS throughout my career. So recently I spent a few days enjoying (not sarcastically!) setting up my new computer and work environment. In doing so, I also took the opportunity to improve some aspects of my development process.

Limited meaningful work on the game itself. From a technical perspective, I could release the demo now, but I'm dissatisfied with the content (specifically the writing). Not that it needs to be amazing just yet, but I want it to be at least less embarrassing. This writing work (for me) requires greater focus than I can usually muster, so I've been procrastinating, polishing other things even though they could ship as-is. Fortunately, at the moment I'm not in any particular hurry.

Since last time, I've mostly finished work on tutorial features and content as well as the other implementations I wanted for the free demo. (As suggested by the same colleague who persuaded me to try genAI,) I also now have an MCP server implemented so that Claude can playtest as a player would, but I've only just started to make use of it. For the modes that are ready, I added full support for keyboard-only play (which was a more substantial effort than I'd anticipated, taking close to two days (very part-time for me, but Claude was fairly busy)). (And some progress on the aforementioned writing, just not much.)

Working on goldy: https://github.com/koubaa/goldy

A new kind of GPU library written in rust with backends for CUDA, DX12, Vulkan, and Metal (tenstorrent and wgpu are planned) and bindings for rust-dynamic, python, c++, c, and dotnet (Java and Fortran are planned).

Uses the slang shader language exclusively. All submissions are expressed as graphs (like cuda graphs), are retained automatically (sometimes partially with a graph partition algorithm), and automatic synchronization of GPU resources. No runtime dependencies (slang is vendored) and new calling convention for shaders using a virtual entry point that allows resources to appear as arguments to the shader 'main'. Includes automatic VRAM and resource recycling for device resources.

Shader coroutines, rust shader authoring, and automatic kernel fusion are planned.

Supports both GPGPU and graphics.

Made it because cross backend GPU libraries usually either target lowest common denominator or are specialized for either compute or graphics or ML. In my experience GPU programs and frameworks are written to target a different kind of machine than a tape machine, but nobody outside of tenstorrent have bothered to describe that machine. So I defined a new kind of abstract machine for cooperative resource-oriented computation called a Fondaco machine for which goldy is the reference implementation.

I am not really working on anything new as such, but I am mostly just polishing existing workflows. For instance, the task for today will be to use mechanize (in ruby) to automatically tap into a webservice which I use manually right now via a browser interface. I want to do this all from the commandline next. (Ideally I'd not want to depend on this and do it locally, but it does various things with .pdf files which I have not yet been able to do myself. ghostscript is surprisingly awful, and while there may be alternatives, I am not too familiar with all of what they can do, whereas the webservice really has all pdf-related tasks already solved, as-is, including optimising for size. For some reason ghostscript produces much worse results, from A to Z.)

Nothing too interesting though.

I have more interesting projects, but these have to come after I focus on more pressing reallife requirements; on my next todo list, though, I want to extend the code I use to compile from source. I track almost 4000 programs already and can compile most of these (for some reason GCC 16.2.0 does not want to compile today); I want to extend this, finishing an automatic build of the linux kernel and full bootstrap into a new system while also adding more language bindings, such as lua. And also allow for this to be compilable via a web-interface.)

Mostly hardware.

A cheap rowing counter. Competitive rowers use a training device that counts their strokes per minute. I figured out that the major parts are really cheap, even as individual purchases, so I wanted to build a budget version. So far it counts strokes fairly accurately and I've just completed initial tests of the display.

Drone experiment. I'm building a image recognition drone from scratch. It's based on a H743 Slim V4, with an RPI5 and a OAK-D Lite. I'm currently trying to figure out why the back left rotor is producing way too little thrust.

Like everyone else, I'm also working on an agent harness. tl;dr I don't trust any agent to not be dumb, but the agents seem to have some success recognizing when the work of an other agent is dumb. In early tests, the back and forth seems to provide more stable and better results.

I've been working on a Persian classical poetry archive with LLM-generated translation. As a poetry enthusiast but a non-speaker of Persian, I wanted to read Rumi, Hafiz, and Bedil, but found myself jumping between ChatGPT and Google Translate. I sourced my data from Ganjoor, which was luckily available via their public API. Then I quickly put together a website with bring-your-own-key translation feature.

For now, there's no backend and it's hosted on GitHub Pages; it's a static website reading chunks from an sqlite-based DB file. I intend to change it in the future by running an LLM (preferably a frontier Gemini model, as works great for Persian) over the whole data set so you won't need a key to read the translated poetry. However, I don't have the budget of $1000-$2000 to spend on the tokens currently.

Lots of fun projects being listed.

Each job runs in a microvm that boots in 400ms from a packed image. Also supports a way to pause on every failure so you or your agent can immediately shell at that point, fix and retry(in a new environment) to verify. Also supports the full DAP protocol so you can interactively step/forward/investigate context at each step/job.

A diffusion-based UI design tool I left Figma to build.

My core hypothesis is that LLMs are trained to write consistent code (good for a billing function), but they also express design through code, resulting in consistent design as well.

Diffusion models are just now good enough to do UI, and are trained on a much wider set of visual data, resulting in more unique outputs. LLMs are now good enough to convert images to code very effectively, so the end result is better even though you have to do a conversion.

Here's a page detailing the standard flow: https://diffui.ai/blog/show-hn

Akariq has taken most of my time [0]. I sell travel eSIM plans for 190+ countries, no app or account needed! Since last time, many HN readers have tried it with very positive reviews. I reply to each and every customer who reach out to me and also implemented some feedback they gave.

On July 24 2026, all major eSIM providers including Akariq faced disruptions. However, Akariq was able to serve all customers even during the downtime either by switching to backup resources or issuing replacement eSIMs free of cost. Some customers of major providers like Airalo experienced serious down time. I wrote more about the incident here and what I am striving to be better in terms of automation etc [1].

One review from a customer in China [2] made all my effort worth it. They said that they were able to use Akariq to access Gmail, WhatsApp etc around the GFW. It even worked smoothly in areas like Beihai and Weizhou island apart from the cities. Tethering with their laptop was helpful too.

I’m currently on the beach at Google (since mid July), so I’m looking internally and externally for a new role. But I’m exhausted, so I’m playing around with local LLMs and DeepSeek more as well. I’m currently trying to get an agent harness going where orchestration happens via bazel, and agents are completely isolated beyond what context you give them access to as expressed in starlark. Agent executions are organized as a DAG like a build would be, where the output of one agent can serve as context for another (there is also a feedback mechanism which is needed for arbiter nodes).

I’ve mentioned it before, but we can get some pretty good results for developing implementation and tests with this setup. The context isolation makes it easy to separate test and code writing using a specification as a source of truth. Tests are then run by an arbiter that feedback to tests or implementation depending on who it blames for test failures. The tests are then treated as an independent implementation, and through the math of coincident errors, the arbiter feedback loop ensures that both are eventually correct (N-versions and clean room research did this with humans in the 80s). This then allows us to use less reliable LLMs to develop code, like Qwen on a MacBook Pro.

I hope to have something out on GitHub before my beach period ends (well, if I’m unsuccessful in getting a new role, then I’ll have a lot more time to play at least).

I lead development on Pindigo (https://pindigo.app), a social score-tracking and ranking app for pinball players.

Most of my time lately has gone into Flippd, its successor, which we recently soft-launched. We’ve also released a tech demo that uses custom computer-vision models to identify a pinball machine from a photo and extract the player’s score.

A boat game for 5+ age group!

I was never much of a game developer, but recently my 5 year old son wanted to play a game so we decided to build one together.

It's a boat game, you basically steer a boat in an isometric 2d world, transporting passengers, cargo etc between ports.

As we designed it, the ideas just kept on coming. He made or directed a lot of the art inside of the game (even the audio), and we included friends and family as characters within the game.

A lot of fun to build - hilarious at times. I used Lua and LÖVE2D, building basically a game engine for an isometric world, so that took significantly more time than expected.

If you want to test it [1], please do, but keep in mind it's only in Norwegian, but I am sure most people would be able to figure it out as it's meant for age group 5 and up:

[1] https://apps.apple.com/no/app/b%C3%A5tspillet/id6791630382

At this point our entire extended family and their kids, grandchildren etc are actually playing this, so it's been super fun.

I’m exploring how to use AI for faith oriented experiences and products. There are two specific areas I’m interested in. I’m furthest along with this app in the App Store. https://trysojourn.app

1) grounding LLM scripture references in the actual text and eliminating hallucinations. This is the platform for that. https://withlattice.com

2) how to use AI to get people into scripture more as opposed to being a substitute for it. This is the product I made for it - it uses #1 above. https://trysojourn.app

I’ve been playing around with exploiting LLMs having ‘read’ every book ever written to make a chatbot to help people choose library books. You talk to it a bit about things you’ve read, and it uses the llm’s latent knowledge of books to suggest ones you might like.

It’s pretty fun! It might even work on your local library (I got carried away and spent a while making it work on a few thousand round the world - you can see the coverage here: https://leafle.nanosheep.net/coverage).

I started making a programming language that is designed to encompass frontend, backend, database, container, and cluster, so that there it is not necessary to stitch together other languages.

It uses functional programming and event sourcing to try and effectively "solve" modern distributed web application development, so that your app code in this language can be extremely simple but not have bad architecture and gaps.

I'm probably oversimplifying the complexity, so I don't even know if it's feasible, but it's pretty fun to give Claude my crazy ideas and see what happens.

👤 alasano
I'm working on what could be described as a Ralph Loop on horse steroids.

It's an externally orchestrated (meaning it's not the agent running the loop) spec driven agentic build system.

A bunch of buzz words but essentially it's a tool you use as the last step after planning your work and writing a spec, to actually have agents write the code.

But it happens within an orchestrator that is durable and which coordinates layers of agents to build -> verify -> review -> triage -> fix -> verify fixes , until the code you get as a result is as close as possible to exactly what you specified.

So you can plan however you want, use whatever harness or agent etc and then just delegate the build to the engine (MCP server or CLI)

You can mix and match models from any provider for any part of it.

I'm building this because I think micromanaging agents is what causes AI burnout and because I want to be able to plan work, walk away and come back knowing it's been correctly implemented.

I'm slowly working on a spacecraft design webapp: https://vesperastro.com. Think PCPartPicker for spacecraft.

You can build out and trade hardware in the master equipment list and immediately visualize how any changes impact mass, power, propellant, and link margins, or break power or data interface compatibility. You can also play around with orbit and operating modes to optimize things like orbit average power.

I'm hoping it can be useful in rapidly iterating early stage spacecraft designs and weighing system-level trade studies across CONOPS and hardware. Its still very much a work in progress so I'm always open to feedback.

Many/most large repos have a set of hand-authored scripts for doing these kinds of checks, the tool I'm building basically packages these in a fast, reusable and extensible tool, with some niceties added.

I'm working on a platform for context management that includes apps that operate on structured text formats (e.g. YAML, JSON, XML, MD) and provides editors for structured text formats (code editing using codemirror, markdown editing using prosemirror) and eventually all media assets (images, videos, audio).

The idea is you have a set of sources (e.g. Github, Google Docs, local file system), a bunch of transformations (templates, apps, llms/gen-ai, simulations) and sinks (communicated through changesets). The platform is like a cache layer that connects these together and allows for a graph of operations (source->executor->sink->source->executor->etc.) which allows for tracing the lineage of assets through a system.

It's an impossibly large vision made barely possible with agental coding assistance.

I’m working on The Marvelous Brass Chessplaying Automaton, a chess app for Apple platforms:

https://testflight.apple.com/join/mqfhpmHY

This work is motivated for my lifelong love for chess, my passion for Apple hardware and software (not as much as before, sadly), and my frustration of not having an Apple-native app comparable to ChessBase. My disappointment with the trend of recent macOS apps using Electron or other cross-platform frameworks instead of the native toolkits is also a factor. I miss the days when Apple users demanded more from macOS apps.

My aim with MBCA is to create a serious chess app that satisfies the needs of everyone from club players to professionals, with a native Apple look and feel and iCloud sync. Currently the app supports the iPhone, iPad, Mac, and Apple Watch. I hope to make a visionOS port later. There is still a lot of work to do, but I’m having a lot of fun developing it, and I already find the current version very useful for my chess training.

The name, in case you wonder, is from a short story by Gene Wolfe, my favorite science fiction author.

I've pivoted to game dev because I'm burned out on AI dev tools.

Imagine a combination of X-Com 2 and Starcraft using cards, set in a world reminiscent of Arcane but 10,000 years in their future when humans have ascended to godhood and colonized the multiverse.

It's been a lot of fun, Godot and agents have taken most of the pain I remembered from my childhood attempts at game dev out of the equation so I can focus on game mechanics, art and lore. I'm almost ready to start soliciting external playtesters (which I'll admit is a bit stressful), I just need to clean up the UI/card templating/art/tooltips/etc so the game is accessible out of the gate and I don't churn for reasons other than the gameplay not being tuned yet.

Climbing gym photogrammetry. My idea is that route and climb recordings is best recorded against a 3D climbing gym model, rather than a plan video, and technology has gotten good enough to do with a regular phone.

As a climber myself, to climb effectively, one has to review their own climb, and with other people. 4D video, body positions across time, is very helpful in improving climbing. I managed to get a reasonable result (far from good) from one video, rather requiring multiple camera angles.

Haven't gotten to monetization yet, but I am enjoying every moment of making it.

I’m working on “nah” [1] an agent hook guard that blocks catastrophic agent actions like filesystem destruction, secrets exfiltration, and git disasters.

All the agent hook guards I’ve seen can be easily removed by agents (and they often do so they can get going with the task). I made mine harder to remove, and I’m working on making it impossible.

I also made “nah” easily extensible. Just point your agent to the docs which ship with the CLI, and ask it to build a custom guard.

I’m working on strong Python and Typescript pseudo-interpreters so I can detect disasters in inline code with less false positives. Bash parser is already very strong.

This is a side-project that I want to be proud off. I spend a lot of time designing, not just coding.

I have a Pebble Time 2, which is an open source watch. I built a voice operated AI assistant for it.

It's hosted on a VPS, connected over Tailscale, and has a realtime TTS server (Piper).

The Pebble has built in transcription, so my app takes the transcript, hits the server endpoint with three possible paths:

1. Deterministic response

The server looks for certain triggers from the transcript like "Add task," "Complete task," "Set a timer," etc that will run a simple function on server and write / retrieve to a database, no LLM call needed. It then responds with the TTS output and the watch speaks. This path is nearly instant.

2. Fast response

If no trigger is found, then it hits a gpt5.6 Luna endpoint, which decides if it can answer the query itself, or if it needs to defer to the big brother model. If it can handle a query itself, it usually responds to simple questions in less than 8 seconds. It's also good about properly deferring, very close to 100% after a few weeks.

3. Deferred response

The VPS hosts a Hermes installation, and for more complicated tasks or for ongoing projects the Luna router sends it to the Hermes agent. This is typically quite slow, as you'd expect, but remarkably capable. I built the voice app to cache a few lines like "this will take some time" which will automatically trigger if the router indicates it's deferring, and then will respond with the full response from Hermes once it's finished (sometimes minutes later).

Pebble has a quiet mode, and my app will only display the text response if it's on, otherwise all responses are run through the TTS. Piper is so fast that this adds almost no time to the response.

In only a few weeks this has become the primary way I set up tasks, review and close them, set timers and reminders, log my weight, check in on the progress of projects I'm running on Hermes, and ask simple day to day AI questions.

Since Pebble is open source, AI tools are very good at building it, and it's trivially easy to set it up so that you can just ask the model to deploy it live. It's an awesome experience to tell it to change something, and two minutes later, that change is on your wrist.

Very fun project!

Waystops (https://www.waystops.com), a map-based travel app for working out what destinations exist and which are actually worth visiting.

Google Maps is great for route planning and looking up things you already know about, but it's pretty useless for discovery. Sometimes you just want to know what places are actually worth going to as a tourist or backpacker.

It's the kind of information you'd traditionally get from guide books, but in a format that IMO makes a lot more sense - a map. Right now the scores and content are seeded by an AI, but the idea would be for these to eventually be user-derived.

It's still pretty early and I have a WIP native app which makes it a lot nicer to interact with on mobile, but it would be awesome to get people trying it out already. It's free to use, with nothing paywalled or anything like that. I'd only think about some kind of monetization if it actually gets some traction. Would love any feedback!

Working on an Agentic IDE (free) - multiple AI agents support + classic IDE experience

BETA - means, production ready, but not still extending and experimenting with features - I keep working on it, and collecting feedback.

I am working on agentic infrastructure for deploying very small production apps en masse.

In particular, I’m exploring what the infrastructure should look like when agents are the primary users: deployment, databases, domains, secrets, observability, and lifecycle management.

The goal is that everybody and their pet can deploy an app.

These units are called saasies, and the project is Saasie.

I've slowly been making some tiny apps that just don't collect data in anyway that I want to use myself, pretty basic stuff. I'm sure there are plenty of them but I feel like it says something the world of smartphone apps that they're hard to find.

I have started working on a 1 Person RTS project (crazy right? i know :D)

Basically a 2d rts, fully orthogonal view, plays in space with spaceship combat.

You start with a deployable base, kinda like the old C&C, which you can place around a minable planet. Than from this you can place further structures arround that planet including the typicals, mining (2 types) of resources, researching stuff, and building ships.

The 2 things i focus the most on in this game on are

1. Responsiveness. Im a strong fan of starcraft 2 (and brood war) and have spend tons of time playing sc2. I love this super responsive controles and its the only thing i will settle for in terms of controles

2. I love the game starsector (yes no rts) for the way its ships are designed. You have a base hull that has some stats like hp / speed / etc - than this thing has basically mountpoints where you can fit weapons into. I always loved this system. So what i build is a game where you can (outside of battle) define your desired ship blueprints combined of a hull, weapons and "inbuilds" (as in upgrades). You can than just build those ships ingame.

So ye made quite progress so far , not sure tho what will be the first mode i focus on once i get a playable (as in demo) state.

Btw using godot engine as base, but some logic is running as c++ gd extensions (rts is heavy calcs , gdscript is just not fast enaugh (or im just not a gamdev ¯\_(ツ)_/¯)

Here a screenshot of the ship blueprint editor for those who are curious - https://i.postimg.cc/bq5JB9J7/editorexample.jpg

The incumbent here is SpielerPlus - practically every handball team in Germany uses it, and I've yet to meet a coach who's happy with it. That gap is the whole opportunity.

Most inventions are just better versions of things that already exist - I'm building the Google Workspace for clubs.

Making rent as an open source developer.

Desperately trying to attract new monthly sponsors and people willing to buy me the occasional pizza with my terrible HTML skills. Is it working?

If any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent. Feel free to contact me.

I’ve been waiting for a spine surgery and to do something with my time I started experimenting with an idea I had. It completely pulled me in, and helps me to distract myself.

It is work in progress, lacks of documentation, I am not even sure I will release it.

About 100 games and still yet to finish 1..

..but I get to take the common stuff from each and put it into an open-source Godot framework so as to not feel totally useless :')

https://github.com/InvadingOctopus/comedot

and all of this is making me want for a better programming language designed from the ground up for games, with no need to care about hardware, so I've been brainstorming and rubber-duckying about that as well.
