One of the great things with meeting up with other developers is to get a glimpse of how they do things and get this "I didn't know you could do that!" moment. Learning new things is always great. There's a lot of little functionality or tools that are so useful, but that many people are not aware of. In this talk, I'll share as many of these tips, tricks and tools as I can, as quickly as possible. I'll cover various areas of webmapping, from MapServer to GeoExt, from user interface to server administration. The goal: leave with new ideas.
