- 🚨 Any #AdventOfCode friends at GitHub? AoC users are getting '429 Too Many Requests' in response to the github.com/login/oauth/... request step of the OAuth flow. Last time this happened, I think someone at GitHub tweaked a rate limit in my OAuth app.

- Reposted by Eric WastlAnybody else want to join me in taking the #chill, casual fun approach to #AdventOfCode? We'll help each other out when we get stuck, celebrate each other's wins (no matter how small), and generally pursue AoC as a collaborative game (not a competitive one) Let's have some chill holiday fun, y'all!
