I invite you to the yearly Berlin hackathon. It's 1-3 June and registration is now open. If you need financial assistance or help with hotel/hostel, just mention it in the registration form. https://wmberlin.eventbrite.com/ This is the premier event for the MediaWiki and Wikimedia technical community. We'll be hacking, designing, and socialising, primarily talking about Gadgets, the switch to Lua, Wikidata, and Wikimedia Labs. 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!
