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.

Need help finding good python solutions
I got all but one star in 2020 when I did it in Python: https://github.com/ednl/aoc2020 but I'm afraid there may be some short variable names despite not doing it for speed.

2015-2022: What solution to a problem are you the most proud of
I liked my solution for https://adventofcode.com/2020/day/17 Game of Life in 3D and 4D: https://github.com/ednl/aoc2020/blob/main/day17.py

2020 Day 8.2 in Python - trying to figure out how to do this efficiently?
Day 8 runs in 0.02 s using python 3.9 on my M1 Mac Mini. Just flipping in part 2, no special optimisation. My code: https://github.com/ednl/aoc2020/blob/main/day08.py

[2020 Day 6 (Part 2)][C] Works on example but not on puzzle input. Can't figure out why.
Good that you got it working! My version in C is a bit shorter, perhaps you could use some ideas for the next puzzles? I like the dynamically sized getline() function, for instance: https://github.com/ednl/aoc2020/blob/main/day06.c

[2020] Optimized solutions in C++ (291 ms total)
Day 23 part 2 in 0.06 s on a dual core 1.3 GHz i5 Haswell (2013 MB Air) https://github.com/ednl/aoc2020/blob/main/day23.c because of a simple array as a linked list.

[2020 Day *][C99] Computers are fast: AoC 2020 in < 2s, including compile time
Day 23 part 2 (1 million cups, 10 million moves) runs in 0.06 s on my 2013 dual core Haswell i5 1.3 GHz. Main reason is a super fast simulated linked list via a pre-allocated array of integers. Source https://github.com/ednl/aoc2020/blob/main/day23.c

-π- 2020 Day 24 Solutions -π-
Thanks to /u/thomasahle for encouraging me to implement axial coordinates, which made it a lot easier. Also thought of a better way to parse the input in one go. And this allowed me to tighten up the grid dimensions. Runs in under a second on a very old laptop, half of which is because of the scipy import ... https://github.com/ednl/aoc2020/blob/main/day24alt2.py

-π- 2021 Day 19 Solutions -π-
Python in ~50 lines. Neither particularly elegant nor super-efficient, but completes in a few secs and only required limited interactions with the hell of linear algebraic rotation matricesβ¦

2020 Day 20 Solutions
So far, this is the only day that looks to be impossible (merely compressing the necessary instructions, would likely go over 512 bytes)β¦ But I'd say my current iteration is still fairly short and readable.
Python in ~40 lines, optimised for 1. concision 2. clarity (definitely room for optimising time complexity).
