Caffeine 1.0 For Linux Released

Caffeine is a Gnome applet which basically prevents your computer's screensaver and power saving to activate. The applet works simple but effective: a coffee-cup will be displayed and when you click it, the coffee-cup fills up and keeps your computer from going to sleep.

Imagine that you’re giving a presentation. The room is illuminated only by the blue glow of the projector, displaying your slides on the screen behind you. You linger on a particularly crucial slide, carefully explaining the subtleties to your mesmerized audience. Several minutes pass, and just as you are about deliver the stunning conclusion, the projector goes dark, displaying only a tiny “No Signal” message in the bottom corner.


But that's not all: Caffeine can automatically start prevent the screensaver and power saving when playing a game, watching a flash video in Firefox (YouTube, Hulu, etc) and even while playing Quake Live.
