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] [Rust] Solving Advent of Code 2020 in under a second
For instance, I wrote this in C for day 15 https://github.com/ednl/aoc2020/blob/main/day15.c which runs in 1.635 s on a Raspberry Pi 4 (4 GB, RPiOS 32-bit on SSD, overclocked to 1.8 GHz) when timing on the command line with "time", taking the lowest "user" value of about 10 manual runs. Compiled with gcc -Ofast (version 8.3.0).
Yep, linked above, or: https://github.com/ednl/aoc2020/blob/main/day15.c

[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

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 -🎄-
Python, Numpy, SciPy Took me a while to figure out how to calculate the new state with different kernels for odd and even rows. In the end, it means doing almost twice the work. Still about 9x faster than the native Python version I did first. Part 2 below, full code at https://github.com/ednl/aoc2020/blob/main/day24alt.py
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
