In two and half weeks the likely biggest Linux Event kicks off: LinuxTag 2008 in Berlin. Four days of exhibition and more talks (the organizers say 240, German/English mixed) than ever before. I plan to be around all the time. 
On Wednesday everyone's darling, the multi-headed president of KDE e.V. and the galaxy, Aaron Seigo will give a keynote about KDE4. On Friday is a day-long track with KDE talks, on Saturday is openSUSE day and there are separate talks about Amarok and Kontact planned. Additionally there will be of course KDE and openSUSE booths all the time.
Special tip: one can travel for 59 Euro from everywhere in Germany with ICE to LinuxTag/IT Profits and back.
Thanks your special tip
It was quiet funny to order the ticket on the hotline, but finally I was able to get one. The event name is "IT Profits 4.0" " IT Profits" does not work.
