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

#412I'm working Solarite, a library for doing minimal DOM updates on web components when the data changes. And other nice features like nested styles and passing constructor arguments to sub-components via attributes.

#414I'm building https://aero.zip, an E2E encrypted, resumable file transfer tool (think WeTransfer but encrypted and not P2P). I just posted it to Show HN:

A few technical details I enjoyed working on:
* Streaming ZIP: To allow downloading multiple files as a single archive without buffering, I implemented a custom streaming ZIP64 archiver. A Service Worker intercepts the request, fetches encrypted chunks, decrypts them, and constructs the ZIP stream on the fly in the browser.
* OPAQUE auth: I used the OPAQUE protocol (via serenity-kit) for the password-authenticated key exchange. It ensures the server never learns the password and protects weak passwords against offline attacks if the DB leaks.
* Passkey PRF auth: If your passkey provider supports PRF (like iCloud Keychain or Windows Hello), the app derives the data encryption key directly from the passkey, allowing a login flow that doesn't require entering a master password.

#417CtrlAssist – an open source project to bring more accessible, collaborative gaming to Linux! Inspired by PC gaming sessions with my own family, where both young and old relish exploring rich stories with immersive worlds (like Witcher 3, RDR3, Hogwarts Legacy, etc) but find coordinated combat or movement control too challenging to play solo, CtrlAssist lets you combine multiple controllers into one virtual gamepad, much like assist features on dedicated game consoles.

Whether your helping grandparents through tough boss fights, or co-oping with nieces and nephews to level age gaps, CtrlAssist aims to make PC gaming on Linux fun and accessible for everyone. While I’m certain similar utilities exist, I also just wanted a holiday hobby project to practice Rust development while scratching a personal itch.
Please give it a try, share your feedback in the relevant discussion categories, or check out the open issues if you’d like to contribute, help is always welcome!

#418https://mytinycafe.com/ An PWA primarily for my wife and my daughter. They can order their hot chocolate and their coffee as if they were going to grab something at a fancy café downtown, but instead it's at home and I'm the barista. It is quite nice to have for when my wife comes back from work and want something specific, or when we are waiting for the visit of a few friend, they can order exactly the available bev…
It's really super cool!

#419im build an offline-first iPad-focused Dungeons & Dragons campaign app called Campaign Codex. i got inspired by watching Critical Role and saw a bunch of them using iPads during their sessions.
thought it would be cool to build something like this. im still building but feel free to download it via testflight and give some feedback: https://testflight.apple.com/join/kM4udJSZ

#420A few games developed entirely with AI. I'm using GitHub CoPilot to drive the development, and I'm having the AI come up with the graphics programmatically as well. It's a pretty fun project.
