Done right, internal hackathons are awesome. They encourage company developers to build all the crazy stuff that they’d normally never dabble with, be it for lack of time, fear that their co-workers/bosses would think they’re nuts, or because their ideas are just too far from “the company vision” or whatever. When all that’s on the line is bragging rights and beer, people build surprisingly awesome stuff. Like this hack from Netflix’s internal 24 hour Hack Day. It uses the data from a Fitbit to determine when you’ve fallen asleep while watching a streaming movie, and pauses your flick at that spot (watch the embedded video below). But wait, there’s more! Here are a few other entries that Netflix opted to share — no word here on who won.
