You code? Sia dev Luke is hosting an Advent of Code leaderboard! Sign up at adventofcode.com and use this leaderboard code: 30280-93df612d Advent of Code is a programming challenge where you compete to solve a new puzzle each day in the month of December. It's a fun way to learn new algorithms, data structures, and programming languages. The faster you solve the problems, the more points you'll earn. We'll also be giving out swag to participants -- more details on that later.
