Geolocation EXPLAINed

How do you find the location of someone visiting your site? And, how do you do it fast? If you've ever been curious about how analytics services can place your site visitors on a map, or about how to analyze and improve a slow running query, then this talk is for you!

In this session, you'll learn about IP address networking, fundamental database operations, and query performance tuning. We'll develop a geolocation system from the ground up, and make sure it's running lightning fast along the way.
