Here's a pretty in depth blog post about how google maps works. A good geek...

Yesterday afternoon I was trying to search for something on my PC, I couldn't find it. I checked my settings in the MSN Desktop Search and realized it was only indexing Outlook and my My Documents folder. Well, I rarely keep anything in the My Documents folder, so I setup the search to reindex my machine. 15 hours later it finally finished indexing. It indexed close to 500k items on my machine. During that process I figured out there were some virii on my machine as well. So I had Norton do a full system scan last night and it came up with 9 files on my old harddrive which is hooked up as an E drive. Now I guess I should run a disk defrag and try to clean up the drives a little. I think I'm going to write an application to help me archive my many thousands of images. I have probably 100 gigs of photos taken with my cameras, so I need to figure out a way to archive them on DVDs and have a thumbnailing application on the PC so I can tell what images are on what DVDs. That could be a fun little project to start on this...
