I just completed "Movie Theater" - Day 9 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/9
This one was a brain-twister! I managed to improve my initial 80ms solution to 800us using some fun data structures

Written in Rust, like last year. (ugly, because I write as fast as possible for aoc) code can be found at git.emmabyte.de/emma/aoc2025

TIL that my website works fairly well on Android 2 (released in 2009)
The only feature not supported on the main page is CSS variables that I use for colors.

A friend of mine had the idea of doing something along the lines of advent of code, but in his style: cancer.
For that, he needed an easy hosting solution that can publish one puzzle every day. We set up GitHub Actions with Cloudflare pages and wrote about the process

Just finished the first iteration of something you might call an auto formatter, if you're being generous.
It currently completely ignores how the user formatted the code before, and is the most basic one could imagine a formatter to be.

After working on and off on my rust implementation of craftinginterpreters.com, it's starting to feel like just another codebase.
It started off feeling like something special and intangible, because it was my first "real" implementation of a programming language.

I was just compiling some rust and ofc it took a while because it's a huge binary and I made a mistake, so I had to redo it... So I got asked "is that doing some Ai" and now I wonder for how much longer anything software is gonna be "Ai" for.

I really just spent two days redoing half my infrastructure to host my own Bluesky PDS to get my handle until I saw that you just add a single DNS record. At least, I got a refresher on reverse proxies and containers.
Also, now I have another container host, because 6 wasn't enough, apparently.
