Katzenmann@feddit.orgto Advent Of Code@programming.dev•🛜 - 2024 DAY 8 SOLUTIONS -🛜English1·6 months agoRust
Pretty happy with my solution today. I took my time today as it was a bit of a slow day and did it in Rust instead of python. Having proper Vec2 types is very nice.
Tap for spoiler

Katzenmann@feddit.orgto Advent Of Code@programming.dev•🌉 - 2024 DAY 7 SOLUTIONS - 🌉English1·6 months agoMy initial comment was a bit harsh, I’m sorry for that. It was meant to be a bit of a joke. Anyway here’s my code. Do note that I don’t do the challenges timed so I have a bit more time to name my variables accordingly. Takes 35 seconds to run on a pc with a AMD Ryzen 5 5600

Gnome is very different than xfce and has a different workflow. I find the workflow of xfce very nice and like the modularity of it
It’s pretty good. No justifying his behaviour tho

I went all-in on proton a few years ago but I dislike the direction in which they are going now. Does anybody have tips on how (and where) to switch smoothly. I could self host email but I’ve heard that it’s a big hassle
