I know, I know. It's just that Anselm pointed out another place using the geosphere applet. This place is pretty cool, it lets anyone add waypoints and associated information to their dataset and the default visualization for the search tool is the applet: GPSter: Waypoint search. I'd like to add some specific points, but I need to get a GPS device so I can do it accurately.

In other news, I rewrote the applet to accept <group> tags in the XML so the points can be categorized. Then using javascript (or another applet in the page) you can interactively hide/show the different groups. The reason I did this is so when my current Friendster spider-run completes (it's at 7000 of 22000) I'll be able to group the points by the number of hops away from me they are within the Friendster network. I wrote another python application that should determine how many hops away (minimum) each user is from me. It's been running for 5 hours now and unfortunately I didn't code in any output to indicate progress, so I have no idea how long it will take :(

Graph traversal can be time consuming and resource intensive, and I'm running it against a 5000+ dataset of highly interconnected nodes, so if it isn't done by morning I guess I'll kill it and rethink my traversal alogrithm. I didn't really put any effort into optimizing it.
