Rackspace and AppFog are throwing a Happy Hour on Thursday, February 7 at AppsWorld in San Francisco, and we’re asking developers to create an app that helps us choose the beers that will be served at the party.

All you need to do is RSVP to the party, register for the contest, and then create an app (deployed on AppFog and Rackspace) that allows people to vote for which beers will be served at the happy hour.
That’s right, your votes determine which beers we drink! We’ve selected six beers for the contest: Widmer Hefeweizen, Sierra Nevada Pale Ale, Stella Artois, Lagunitas IPA, Newcastle Brown Ale, and Guinness Stout.
We've moved! The Rackspace DevOps Blog is now hosted on Rackspace Cloud Files (powered by OpenStack Swift) using Octopress. This blog was hosted on WordPress, using a mix of various Rackspace Open Cloud products:
