I invite you to the yearly Berlin hackathon.
This is the premier event for the MediaWiki and Wikimedia technical community. We'll be hacking, designing, and socialising.
Our goals for the event are to bring 100-150 people together, with lots of people who have not attended such events before. User scripts, gadgets, API use, Toolserver, Wikimedia Labs, mobile, structured data, templates -- if you are into any of these things, we want you to come!
Some financial assistance will be available -- more details soon.
This event will be hosted by Wikimedia Germany (WMDE) and supported by the Wikimedia Foundation. Thank you, WMDE!
Dates: June 1-3 2012. Barely-started wiki page, no registration details yet: https://www.mediawiki.org/wiki/Berlin_Hackathon_2012 . Organizers: me and WMDE's Nicole Ebber with assistance from Lydia Pintscher and Daniel Kinzler.
Mark your calendars!
