I made https://foragoodstrftime.com/ - which isn't open source (But honestly is just a few lines of code). I made it as I found it useful and hoped others would as well.
Great name

#112I built bip38, a java library for password-protected private keys in Bitcoin (and dogecoin) implementing the BIP388 standard.

And implementations of paper wallets for offline storage using it:

#115I created Lua with C/C++/Java/Javascript syntax https://github.com/mingodad/ljs
Also forked a scripting language https://github.com/mingodad/squilu and extended it to accept a pseudo C++/Java/CSharp/Typescript syntax to make easy to reuse code and have fast iteration when creating new functions (with it and minor changes I could get https://ssw.jku.at/Research/Projects/Coco/ parser to work for easy grammar development).
Create a tool for create, document and prototype database applications at "user level" in near realtime (live) https://github.com/mingodad/db-api-server.
Extended GLPK to accept a bigger subset of AMPL and made some performance improvements in the GMPL interpreter https://github.com/mingodad/GLPK

#116I built a C actor-like event library: https://github.com/FedeDP/libmodule
It actually has lots of improvements in the 6.0.0 pull request that i am delaying because i am too lazy (and haven't got much time) to fully rewrite doc.

#117I built an Android app that lets you create bookmarks for any kind of Android audio track (e.g. played by some music player or podcatcher app). My app, "Stop It!", captures which player app was used, which track/artist was playing, as well as the exact timestamp. I create bookmarks whenever I hear something I like (but I don't have time to pause the playback and make notes). Stop It lets me get back to that particular track and time stamp easily, hours or days later, and avoids that nice things fall through the cracks. The bookmark creation mechanism is to pause playback and immediately resume it, which you can do with any Bluetooth headset - no need to unlock your screen. The app is open source, but not on the Play store. I built it because nothing like this exists... More details here: https://www.augmentedmind.de/2020/08/16/stop-it-create-audio...

#118Currently:
AudioWrangler: https://apps.apple.com/us/app/audiowrangler/id1565701763
Got sick of my Mac using the wrong audio device when waking up, so I wrote a little utility that lets me prioritize which devices to use based on what's connected. It's my first app on the App Store. I'm enjoying learning Swift and using it to write desktop apps!
In the past:
* Lucid: https://github.com/mattgreen/lucid.fish
A pure-style prompt for fish shell that pioneered truly async fish prompts. Still use it daily.
* Fogeybot: https://github.com/mattgreen/fogeybot
A Discord bot for Heroes of the Storm that creates teams for pickup games using player ratings.

#119I made a video input form: https://github.com/wgryc/video-input-js
The idea is that you have a form field-like command that you can record a response with. You can then submit the video via a regular POST request.
I couldn't find any simple tools like this for rapid prototyping different survey responses and experiences. It was fun to build and nice that some people have starred this on GitHub!

#120Elder.js, an SEO first, Svelte framework and Static Site Generator. [0]
Lots of SSGs existed but none supported Svelte and I wanted partial hydration when people said it was impossible.
