I will make this short. The 3rd and so far biggest CakeFest will be held in Berlin, home of Debuggable! From July 9-12, people from all over Europe and the rest of the world will travel to Germany in order to celebrate and learn about the best PHP framework there is.
The even is broken into two parts - the workshop portion (July 9th and 10th) and the actual conference (July 11th and 12th). You can find out more information about the conference at its web site (including registering and reserving your spot!)
