Wormhole 1.1.7 just released with a bunch of bug fixes and usability improvements. It now also includes Linux DEB and RPM packages github.com/wormhole-app...

new spec writing motto: MUST or bust

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

I just completed "Secret Entrance" - Day 1 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/1 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

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.
