I am planning to use Rust this year to refresh my knowledge after having not used it for six months or so. I'm contemplating doing some solution visualisation this year, as I'm always impressed by that when others do it - but very much time availability dependent.

I'm using rust. I'm hoping I'll be able to finish all the days unlike last year.

I’m going to try to use both zig and gerbil. Usually i use clojure, so might fallback to that as well. I started doing puzzles from 2015 this week, and that’s been fun so far

Nobody doing python? It is my first time participating so I think I’ll try it out my strongest language first. I think if I were to try something else it would be Go, to brush up, or Typescript, which I’ve been wanting to learn but haven’t really had an application for, yet.

I'm participating for the first time, using C.

I forgot about this until the 2nd, so I'm a bit behind but oh well.

(Also my day 1 solution is absolutely not optimised haha, especially when I read up to a whole line just to search for a string which is a maximum of 5 characters)

This is my first time participating and I initially thought I would do one different language per day (I don't know how feasible that is, I'll probably run out of "common" languages early on and on the twenty-fifth find myself writing in some old obscure dialect of BASIC if I make it that far :D), but since I started 3 days late (I only learned about this event then), I have some catching up to do, so I think I'll write the ones I'm behind on in python, because that's what I'm quickest and most familiar with, since I don't think I will be able to catch up writing in the other languages.

I've done it with a new language each year in the past, but this year I decided to do it with stuff I'm very familiar with - with an added twist: I have to visualize something for each day.

So I built myself a little app/puzzle harness that serves up the sample/puzzle input and provides some boilerplate so I can just write the x-data for a new Alpine.js module for each day. Then I setup d3 and plan to visualize something for each day using it. For example, I just settled on a simple bar graph (final value of each row) for each part of day 1:

Hoping once it inevitably gets to grids and such, I can do something more interactive. Would love to have something where I can animate or manually step through each step of the solution (such as the pathfinding algorithm last year).

I've decided to catch up with what's new in Python (language itself and the ecosystem). I've set up a repository with pyproject.toml, and git hooks configured, and I'm running pylint, pytype and pytest.

Of course, any feedback (or pull requests) is welcome, especially if you're familiar with all the new things in Python land.

It's my first time participating, and I'll be sticking with Java since I'm getting ready to interview, but might switch to Go midway through if I get bored

Using C primarily, as before. I'm not sure if I'll do all days this time, the later days tend to take up much time and stress me out.
