The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

SIMD intrinsics and the possibility of a standard library solution

Most of the time is spent parsing, but this problem lends itself nicely to a SIMD formulation, which using vectorclass doesn't even require detailed knowledge of the intrinsics. Hot runs take ~14 Β΅s on a Core i9-12900K, including I/O. Full code is (here)[https://github.com/ahans/aoc2022/blob/main/cpp/day04.cc], the interesting part is this, where we process 32 elements at once:
- Significantly faster quicksort using SIMD
- Parsing JSON faster with Intel AVX-512
- What do you think is faster for batch-processing a lot of "double-type" arithmetic?

Scala using Β΅Json. Really happy with how concise this is. I was able to parse everything into a Packet class that extends Ordered, which gives us the compare function. So once that was implemented recursively according to the rules we were given, I was able to jsut call .sorted for part 2.

Scala using jgrapht. I thought part 2 would require a different graph (similar to 2018 day 22) since the story said "to avoid needing to get out your climbing gear..." Glad that wasn't the case!

Scala. Pretty happy with how I parsed these into anonymous instances of my Monkey trait. For me part 2 wasn't hard because of the modulo trick, but because I was using mutable queues. So I had to add a reset() method to get things back the way they were before running part 2

Scala using tail recursion. Not the prettiest, but it works

Scala. Not too bad with my Point helper class. After part 1 I refactored the movements into a move helper that just takes 2 arbitrary points; the current point and the one we are moving towards. Then it was easy enough to just apply that in order each iteration for part 2.

Scala. It's ugly, but it works Β―\_(γ)_/Β―

Scala. Parsing wasn't as hard as I thought it would be using transpose and then just filtering non-alphanumeric characters. I initially parsed to a Map[Int, mutable.Stack[Char]] but then that bit me in part 2 when I would have to "reset" it (dang mutability!). So instead I parse to Map[Int, String] and just build the mutable stacks twice.
