[2021 Day 6 (Part 2)] [Rust] Pretty darn elegant
This lets you cut out the relatively expensive fcount.remove(0) operation, and each loop is basically one addition and a few assignments. Full solution here.

Advent of Code: Day 3
Your solution is pretty much exactly the super concise version of my definitely over-engineered solution.

You can see the code here

Here's my solution

[2015 day 04][Zig] Some tips to solve the problem without brute force?
Your solution looks remarkably similar to my Rust solution which solves both parts in 1.6s on the cheap NUC I use as my coding workstation.

2020 Day 8.2 in Python - trying to figure out how to do this efficiently?
It's in Rust, so I'm not sure how readable you'll find it, but in case it helps, you can see the code here.

Programing midlife "crysis"
I found a single crate with a bunch of binaries worked well. It let me use a shared library easily. You can see my crate organization here if that's helpful.

2020 day 7 (part 2) How would you solve this without recursion?
You can see my code here in case it helps.

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

-🎄- 2020 Day 24 Solutions -🎄-
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
