These gigantic Japanese nerds just rigged up an R2-D2 DVD Projector into a server monitoring system that alerts them whenever a system is down. R2’s got Nagios, a monitoring app, an IR controller, and the ability to project what’s wrong for the people to see. The video illustrates how it works in a dramatically geeky manner. These should be standard issue in every server farm around the world. [Syun – Thanks Motohiro!]
