#AdventOfCode off to a good start! I don't stay up late to do them (because central time US, work and !young) but still plan to get through them this year. When work doesn't slow me down too much I do.
Just doing it in #Python this year - saves me time over doing it in Rust, and also I haven't been doing so much Python recently, so it's nice to get back to it for a bit. If I have extra time I'll probably go back and complete some in #Rust too, I'd like to build more proficiency there still, especially in the tricky algorithmic problems that come later.
