I wrote a blog post about this year's Advent of Code. I had a blast and I am already looking forward to 2026! * All my Python solutions were under 1s using pure Python and 100ms with a little help from mypy/scipy • The AoC community is the best ❤️

Advent of Code 2025 🎄

December is the time for Advent of Code, as it has been since 2015, when the first Advent of Code event was published.

I've finished #adventofcode 2025 and this is the first year that I managed to get all solutions under 100ms ⚡ All but two are under 10ms. Not bad for the slowest popular language out there 🐍, although I did have to use numpy a few times.

It has been 15 years since I joined GitHub 😱
