Thanks to @was.tl we are enjoying #AdventOfCode again in 2025, and I am also running the unofficial/community survey again in 2025! 😊 💡 Take care that it closes "early", late Dec 12th or thereabouts! Consider filling it out if you haven't already: forms.gle/TAgtXYskwDXD...

🚨 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!

Last year, I talked about #AdventOfCode on a podcast aimed not at programmers but at escape room enthusiasts! If you or someone you know would like a less technical introduction to what AoC even is, here you go: roomescapeartist.com/2023/11/28/r...
