Reserved identifiers in C
You aren't supposed to create identifiers that match these patterns, if you're trying to write portable, future-proof C code. But you probably are. We all are.

AoC 2020 day 13, part 2, can't solve
I don't know how to solve this problem. Is there some bit of math knowledge about prime numbers I'm missing? I don't know much about number theory.
I've never had to look at a hint for an AoC day before, and I don't want to start now, so I might drop out.
I don't recognize any of the people on the Merveilles leaderboard who are still participating.

What was the first (known) maths mistake?
Beer, multiple numbering systems, accounting, civilization
