Well the guys at PHP.net are at it again. As quoted from the site:

"From July, 10th to 13th 2003 LinuxTag, Europe's largest Fair and Congress dedicated to Open Source in general and Linux in particular, takes place in Karlsruhe, Germany."

So if you're gonna be in the area, you might take the time to stop by and check things out. They're going to have speakers such as Ken Coar (Apache), Rasmus Lerdorf (PHP), or Kaj Arnö (MySQL). Just check out LinuxTag and PHP.net for more information.
