Advent of Code 2021 in Ruby

02 Dec 2021

Another year of Advent of Code, no tradition like it! 🎄

I’ve probably got even less time than last year (it’s a bad trend right now…), but I’ll do a few just to keep the tradition alive. This year I’ll use Ruby. Don’t have a good motivation why.

Update: after solving a few problems in Ruby, I started getting tired of using a language I’m not that familiar with. It was a great idea the first years and I learned a lot, especially when doing pure FP in Haskell and some actor based things in Elixir, but at this point I don’t really dig deep into the languages - and to be honest, a lot of the languages I’ve chosen are very similar. Ruby and Java are considered different but they aren’t fundamentally that different.

I decided to continue doing some of the problems this year in Java instead because I enjoy the problems and I mostly use Java professionally at this point in my career so there’s no friction when using it. It’s hard to give up a streak of using new languages, but I think it’s a wise decision. When my kids are older and I have more time, I can see myself getting into a real challenge like doing them in APL or Prolog. But for now, I’ll go ahead and enjoy the puzzles with a language I already know by heart.
