DirkCam Update

DirkCam has been live for a couple of days now. At first, the camera took a picture once every thirty seconds, and uploaded it each time. Since Dirk's site has a fairly small and select cross-section of visitors, we think we can save bandwidth by introducing the following: From now on, the camera will only take a picture and upload it if something in its field of view changes. This means that if Dirk falls asleep or goes out, the whole system is saved the bother of messing about with hundreds of identical pictures. The practical upshot for the visitor should be much the same as before, as the minimum interval between uploads is still thirty seconds.
