About fifteen years ago a puzzle game called Trainyard came out for iOS and took my dev team by storm for a few weeks. It ceased getting updates some years ago and isn't on the app store anymore. So I came up with a variant on it and just put up https://www.geoffcanyon.com/lightyard.html I need more puzzles to include in the base pack, if you come up with something interesting, export it and send it to me!

trainyard is/was an amazing game.

Agreed!

Despite the fact that trainyard has been defunct for ~8 years, I didn't want to simply clone it.

I tried to give a similar, but not the same, experience -- I'd be very curious to know how close you think I came.

Hey everyone!

Last year, Mozilla released Orbit, an AI-powered browser summarizer hosted on a GCP server. After people started digging into the extension, they discovered things like backend endpoints such as store_result. Eventually, Mozilla discontinued the project. For the past month, I’ve been trying to rebuild Orbit from scratch, but with one major difference: Apogee is fully local and privacy-focused. Apogee doesn’t send or store your data. It can directly connect to your local Ollama instance for inference. I’ve also added WebGPU integration for Chrome and Transformers.js for Firefox to provide faster, local responses.

It can summarize: Articles and websites, YouTube and Billie videos, Wikipedia articles, Hacker News and Reddit threads.

You can check out the source code here: https://github.com/darshi1337/apogee

Install Apogee:

Chrome: https://chromewebstore.google.com/detail/apogee/pgemlpomhkdc...

Firefox: https://addons.mozilla.org/en-US/firefox/addon/apogeeext/

Obviously it is far from complete. Would love to hear your feedback and suggestions!

TUI file manager with Bitwarden/SFTP/S3 support written in go.

Runs pretty much anywhere.

Current feature in the works is built-in audio player.

As someone who still likes to purchase and organize music in files and directories, I couldn't resist the itch to code a worthy competitor to Cubic Player :)

I am working on vorfract, a Voronoi voxel world which uses Voronoi cells as voxels instead of the regular cubic ones.

It's an early version so many (if not most) things that would be in a game are still missing at the moment (though planned on paper).

One interesting thing is that because the Voronoi voxels are so malleable, things like round or hollow worlds are a pretty natural outcome.

In parallel to working on it, I've been mostly using it to build and improve my own voxel castle with a pointy roof, slanted walls, custom built stairs, tables, chairs and all those nice things.

In the last update I added a CRT filter and some pixelation options as I find that appealing. As for the future (maybe as the next thing?), I guess I'd probably like to add the ability to build less blocky things like round towers (or flower vases!), but that is still very much a work in progress.

The Web version (WebGL) is completely free (and will stay that way):

I've been working on building hyper-local services, sort of as a love letter to my community in Denver, Colorado. Before decent LLM harnesses, these would've been prohibitively expensive in time and resources to build out and would never break even. Now I think I might be able to at least cover hosting costs and tokens; that's enough to keep these sustainable for my neighbors.

Broomsday: https://broomsday.com sends folks emails and SMS the night before street sweeping parking restrictions for their block(s). Email notifications are free, SMS on a paid season pass. The schedule here is block-by-block and easy to forget, so people get ticketed _a lot_ at $50 a pop. The city has an email-only notification service that's free, but it's poorly supported and the interface sucks. This is ready; I'm testing with friends and family currently before attempting real marketing.

HailPass: https://hailpass.com similarly is a notify-before-pain service that integrates a bunch of open weather services (NWS/NOAA mostly, plus a handful of impact reporters and working on a small hail-specific ML model) to give folks on the Front Range 5-10m heads-up before damaging hail arrives at their location. Weather prediction is (not shocking) hard so I'm still tuning to get as much signal out of the noise as possible; some false alarms will be unavoidable but I want to cut them down before even a F&F release. This year's season is pretty much over with, so aiming for an April '27 release.

There's a lot of ski/snowboard/winter sport culture here, but there's also existing services for those, and I'm mostly trying to offer new coverage where there isn't a good option for my neighbors. Might do an ash borer treatment/prevention service navigator yet.

None of this is going to make me wealthy or famous, but building things that help the people that I actually interact with every day and that are a part of a community that supports my family feels _really_ good.

Working on Clor, an agent multiplexer for Claude and Codex with shared memory. It's free on your own machines.

The idea is to help developers multiplex agent sessions and run Claude and Codex together, which is much more powerful than running one or the other alone.

My secret goal is to figure out how to make software development the kind of focused, meditative work it used to be.

Very happy to get critical feedback from any HN'ers: jake@clor.com

I've always wanted to make a video game, and over the past few months have been building one, Fairway Rogue. It's a procedurally generated, deck-building, mini-golf roguelite. It's been a lot of fun, and I've learned a lot.

I remember someone saying that when you build a game, you end up building tools to help you build the game. I never really got that, but now I do. I've spent quite a bit of time working on tools to help me balance the various game mechanics.

One weird learning, it was much easier to get it on the iOS app store, than the Google Play store. Google wants you to have a closed playtest with at least 12 players, for 14 days. I did that and they said the testers weren't engaged enough.

If you want to check it out on iOS https://apps.apple.com/us/app/fairway-rogue/id6783598189, I'm still trying to get it on Android

I’m working on an app to help my late diagnosed ADHD - through sound.

The app wraps whatever is playing on mac through device convolution (old radio, hifi system) - Room convolution (a bedroom, a forest) and adds ambience (rain, wind, waves) and Apples spatial processing - so it sounds like a real space.

For me - hearing the sound in a space really helps more than just the dry sound.

TLDR power user work out tracker, all PRs, metrics, fast keypad input or codemirror syntax input if you're lazy type that jots in notepad. Generate any exercise based on movement + modifer system. Mountan of metrics (your basic lifitng stuff), rolling averages etc. Fractional set tracking, bodypart volume... too much to list. Build and import programs using syntax.

Lazy overview while I work on docs.

Looking for users to stress test at some point, but feel free to play around.
