A friend and I made an app for photo memos. The idea is to use it instead of the camera when you just want to remind yourself of a thing. Originally we wanted to challenge ourselves to write the app in 24 hours, but it predictably stretched out (quite) a bit.

#52A bunch of different things, few of which I got actual traction on, in true ADHD form (though some of that was being unable to go to the local hackerspace, for hardware work)
One thing which has been rather fun and successful, is speeding up uutils' implementation of integer factorisation: https://github.com/uutils/coreutils/pulls?q=is%3Apr+author%3... (uutils is a Rust reimplementation of the GNU coreutils and findutils)
I'm not yet satisfied with the performance, and I still have quite a few ideas how to improve it, but it's still more than 44 times faster than it was when I started (measured on factoring everything between 2 and 10⁷; it's a lot more on larger / more-interesting sizes)

#53I've been following this book to learn how to parse/interpret/compile languages: https://craftinginterpreters.com/
And started designing and implementing my own pure-functional, JavaScript-targeted language with features like built-in partial-application of arguments, and every function being able to be called in a prefix, infix, or pipeline style

#54Nothing of any importance. Managed to screw myself up to the point of having constant generalized anxiety, so yeah, things are really working out here.
Hang in there. These are strange times and the most we can ask of ourselves is to get through them.
"Little things", like kind words, are not insignificant. Thanks, sincerely.

#57Didn't build as much as I dove into NixOS. Really enjoying it so far.

#58I created a YouTube series teaching entry-level programming in JS, in Esperanto. Because why the hell not.

#59I started implementing a version of APL, but that have taken some significant steps away from traditional APL, and introducing features that normally would not be seen as fitting with the language. It's still an experiment, but some of the key features are: immutability, lazy evaluation, first class functions, a macro facility and automatic parallelisation (the last one doesn't really work as well as I would have hoped).
I started the project in January, so I guess this counts?
Here's a video showing what it looks like:

#60I built an Alexa skill that sits in front of the local council's website (South Worcestershire, UK) and tells me which set of bins go out this week. Have already probably saved myself more time from looking up the website manually than it took to build the skill. Code at https://github.com/morgan-murray/bin-day
