In-reply-to » I finished all 12 days of Advent of Code 2025! #AdventOfCode https://adventofcode.com — did it in my own language, mu (Go/Python-ish, dynamic, int/bool/string, no floats/bitwise). Found a VM bug, fixed it, and the self-hosted mu compiler/VM (written in mu, host in Go) carried me through. 🥳

@prologic@twtxt.net How on earth did you do that so quickly, especially day 10? People were struggling with this a lot. 🤯

In-reply-to » Day 9 also required some optimizations, if you aren't careful, you end up with really inefficient algorithms with time/memory complexity beyond what a typical machine has 🤣

@movq@www.uninformativ.de I shrank Day 9 Part 2 from “cover the whole map” to “only track the interesting lines.” By compressing coordinates to just the unique x/y breakpoints, the grid got tiny. I still flood-fill and do the corner-pair checks, but now on that compact grid with weighted prefix sums for instant rectangle checks. Result: far less RAM, way less CPU, same correct answer.

In-reply-to » i've learned a lot of lessons from writing my notes app, gonna apply this to bbycll and refactor the code to make it way more legible cause my custom templating system is only kind of a giant mess

@zvava@twtxt.net I figure I will know when it is ready, the day I see you using it. Can’t wait! :-)

In-reply-to » Use more WebP, I guess.

@prologic@twtxt.net @movq@www.uninformativ.de h.265 is from 13 years ago and support is still incredibly spotty (though it being proprietary probably has a lot to do with that)

also see: jpegxl’s adoption (three or six years old depending how you quantify it) which afaik is mostly attributed to google deciding not to put it in chrome (though they changed their stance recently iirc (webp, of course, did not have this problem since it was pushed so hard by google (the browser wars never ended)))

really love this design language i borrowed from firefish/misskey v12, you can even select a bbycll theme in zinnia to make things even more confusing :3 though i myself somehow see past the similarities just knowing how different the codebases are
