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.

Compare Search Results Between Google and Caffeine, Side-By-Side

Google is in the process of implementing some very major changes to their search algorithms and this can therefore alter the existing rankings of your web pages in Google Search results of the future.

For instance, if one of your web pages is currently ranked in Google at #3 for the phrase "wallpapers", it’s quite possible that the position may shift either ways after the new version of Google goes live.

Google has created a preview site (Caffeine) where you can play around with the upcoming changes before these get pushed to the main google.com website. And that is expected to happen in the next few weeks itself.

If you like to compare the existing Google ranks of your web pages with that of the future, check out Compare Google - this tools places the top 20 results from the old and new search engine side by side so you can easily figure out how your site will perform in the future.

Another Google comparison tool is located at Cartercole.com which, unlike Compare Google, displays Google search results in their original form - this is perfect for queries that trigger Google Universal Search so you can know what images and video clips results will get displayed in Google Caffeine for your queries.
