For anyone interested, advent of code is about to start! (first puzzles dropping at midnight ET which is in around 11 hours)
We have a community in the instance at !advent_of_code@programming.dev for discussion about the event and that will have solution threads where you can post and compare against other people
Advent of code is a programming puzzle advent calendar where new puzzles drop every day until the 25th. They can be done in any language and puzzles are released on the AoC site
In the past, people have stolen the problems to use in their own challenges, coding tutorials, and even commercial projects. The author has asked people to keep their inputs out of git or anywhere publicly searchable.
