Daemon to keep track of reddit's /r/thebutton April Fools 2015 prank. You'll need io.js (or run node.js with --harmony), a Redis server running locally, and the packages needle, redis and ws. You'll probably want to run this with systemd or something else to restart it, as it doesn't have bulletproof error handling.
