This is very close to the date in question, but better late than never! And I'm sure that, if you were already planning on attending BeGeistert, this was the last step you were waiting for. Registration is now open for this upcoming weekend's BeGeistert, held in Dusseldorf, as usual.

This year it seems there won't be a coding sprint unfortunately (unless something changes), but you can and should attend the weekend of course, so head over to the link above and sign up for a weekend of Haiku and cola, lots and lots of cola.
