Got into the weeds a bit with today's Advent of Code (which I'm trying to solve using Rust, a language I don't yet know, combined with copious amounts of Copilot and ChatGPT to help me figure it out)
Sticking point was figuring out an idiomatic Rust way of reading a file three lines at a time - eventually got to something I didn't really dislike, but it was a messy process: https://github.com/simonw/advent-of-code-2022-in-rust/issues/4
Now reading https://fasterthanli.me/series/advent-of-code-2022/part-3 for a VERY different solution to the same problems
