I have added two events to .
I will visit 20C3 at least one day, while travelling back from Germany to Vienna.
In February I plan to visit FOSDEM, because I have never been in Brussel.
In January I already planned to visit NordU. They now have the program online. 2 Full days FreeBSD 5.x tutorial with Kirk McKusick sounds interesting. Unfortunately I couldn’t find any information about how to pay.
