I finally got my yaml task runner to a workable state.

Getting the parts that I absolutely HAD to implement while not descending into feature-creep hell (driven by my own curiosity) was challenging.

Then again so were the self-debates about the syntax and documentation.

Maybe one day I’ll learn Go or something, but until then - Boku is my yaml-based task runner written in Python.

I’m building Electrobun ( https://github.com/blackboardsh/electrobun ) It’s an alternative to Electron/Tauri that uses Bun. It has a bsdiff based update mechanism that lets you ship updates as small as 4KB, a custom zstd self extractor that makes your app bundle as small as 12MB, and more. I’m currently working on adding Windows and Linux support.

Excited for this!

On my free time I've been making a small "game" where you control a spacecraft using a 6502 computer. You can control things like thrusters, antennas and read data from star sensors, gyros, etc. using memory mapped I/O directly and you can't control anything directly. The whole thing works pretty well, it's built using Godot & a custom Rust extension with the 6502 emulator & assembler. It can even be exported to the…

Very curious, email me?

litevna.app - a DICOMweb compatible medical imaging archive, built on cloudflare workers, to optimize fast image delivery globally. Images are all encoded as HTJ2K for progressive image loading, and the popular OHIF zero-footprint DICOM viewer is built in.

Building mainly to power the next generation of pacsbin.com, but may offer as a standalone service as well.

Been working on a single-pass WebAssembly JIT compiler (atm only guaranteed to work on M1 air), been super interesting learning and thinking through strategies to balance fast compilation & fast generated code. It's the fastest single-pass JIT output-wise that I'm aware of, but the compilation speed could use some work.

Also: the README is pretty outdated, the real interesting stuff happens in https://github.com/csjh/mitey-jit/blob/main/backend/arm64/ba...

I was reading a lot of technical books and kept highlighting things I wanted to remember — but I rarely went back to review them. The notes just sat there, on my Kindle or in the reading app. So I started building something simple: a tool that lets me turn highlights into flashcards with as little friction as possible. Just select text on your iPhone, share it with the app, and it creates a flashcard using AI — a Q&A…

Nice. Minimizing UX friction is always difficult and this is clever.

Building (https://estan.ai), an AI that reverse-engineers real estate listings by pulling not just from public records, but also social media, neighborhood forums, historical sales, and user reviews. It flags red flags—like crime trends, sketchy development patterns, neighborhood trends, and so on—then presents them in plain, opinionated language.

Goal: replace the vague boilerplate of listings with something closer to a paranoid friend who's done way too much research. Curious if this kind of subjective, context-heavy analysis adds real value—or just noise.

A new YouTube app/player, for my kids. It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood. Visually it looks the same. The suggested videos come from predefined buckets on topics they love. E.g. 33% fun math, 33% DIY engineering, 33% creative activities. Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with…

Nice idea. Do you have a timer .. like after a half hour of playing it recommends them to go outside and play (after checking with parents)?

A timer is a great idea.

I’ll add it to our community ideas Google doc.

That's an interesting project!

We have an opening in Wasmer to work on the compiler side of things, I think you could be a great fit: https://www.workatastartup.com/jobs/15822
