You're invited to San Francisco's first MediaWiki hackathon, January 20-22, 2012.

If you're a developer or designer and want to build an application on top of MediaWiki, or using Wikipedia content, please participate in our hackathon in San Francisco (January 20-22 at pariSoma). We'll bring together our senior coders with new developers to build applications running in MediaWiki itself, on mobile devices, or based on Wikipedia's content and data.

This is a free event put on by the Wikimedia Foundation, the non-profit that runs Wikipedia and maintains MediaWiki. You'll get a brief overview of all the key technologies you need, and then you'll have a weekend to build something amazing and make it open source. At the end, show it off and take the next step to get it running on our servers. Join us Friday night for drinks and conversations, and get ready for a weekend of coding. Food and drinks provided. :-)
