Using Waifu2x to Upscale Japanese Prints

Signalfd is useless
UNIX (well, POSIX) signals are probably one of the worst parts of the UNIX API, and that’s a relatively high bar. A signal can be sent to your program at any point when it’s running, and you have to deal with it somehow. Traditionally, there are three ways …

Inside Look at Valve's New Lighthouse Tracking System
While walking around the Bay Area Maker Faire this weekend, I stumbled across an amazing piece of technology: Valve's "Lighthouse" tracking system.
