We're 25% of the way through #AdventOfCode 2025! How is everyone feeling? Learn anything cool? Make any neat visualizations?? Ready for more???
🚨 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.
The first #AdventOfCode 2025 puzzle comes out in about five hours! What's your plan? What language(s?!) are you using? What's your IDE of choice and why is it Vim? Do you have a comfy chair? Did you check out the beta release of Lua 5.5? How much sleep have you gotten? Drinking enough water? 🌟 ❤️ 🎄
Anybody 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!

Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more: adventofcode.com/2025/about#f... adventofcode.com/2025/about#f...
