Advent of Code 2024

See Advent of Code for details.

It reminds me of the Lego advent calendar where each model is a tiny investment in time to build it. I look at Advent of Code as a similar low-investment opportunity to practice some coding on puzzles that can be interesting without having tons of gotchas.

Why Ruby?

I'm doing them in Ruby because while I'm not an expert, I know it well enough and I could use some more practice.

I'm more knowledgeable in Java, but it takes more work to get anything done in Java. I feel my knowledge of Python is not quite strong enough; I would spend even more time looking things in the language. I could have tried JavaScript, but I feel Ruby is a little better at parsing text than JS.

I could have tried Groovy, but it's been a while since I've coded in Groovy and it has been losing popularity lately. I feel that's unfortunate.

Why Are There No Tests?!?

I just tinker on these late in the evening. For these, I care more about coming up with a solution that I find elegant than adhering to strict engineering discipline. I try to keep the code "simple", so each solution is a single script that operates on an input text files and writes to stdout.
