Sadly there won't be a BeGeistert this year. However, we are still setting up a coding sprint.
The event will take place in Toulouse, from 20 to 24 November 2017. It is right after the Capitole du Libre, a local conference around free software things where there will be talks and/or workshops about Haiku as well (most likely in French, however).
If you want to help with development of Haiku or some 3rd party application, you are welcome to stay for the sprint. We will have beds and food provided, so you have nothing to take care of and can spend most of the time coding without much distraction.
I have set up a webpage for the event: http://pulkomandy.tk/kdc/
Please let me know if you plan to attend, so I can have a rough idea how many rooms I should book.
