e^x and a constant were walking down the street, when up ahead they see a differential operator.
The constant screams, "Ahh, I'll be reduced to zero," and jumps into the bushes.
e^x says, "Ha, I am not afraid," walks up to the differential operator and says, "Hi, i am e^x."
The differential operator smiles and says, "Hi, I am d/dy."
Well, technically, there is a different -
Geocaching is primarily GPS based, and locating position with the help of satellites that provides longitude and latitude coordinates, and is very accurate.
This Urban Tapestries is GSM/GPRS based, using a mobile phone, locating a position with the help of surrounding mobile phone base stations. The accuracy of a position is dependent on the site topology, and could be anywhere around 10-50 meters radius in urban context, for example.
Application wise, I think each serve slightly different purpose too -
Urban Tapestries will probably do a information push when one is within a vincinity, and may not require one to actively seek it, except to give Urban Tapstries permission to push. This also means that it could be subscription based.
Theoretically, it could be possible to use geocaching caches(it's data) in GSM environment. However, the geocaching cache's seeker will probably have a harder time, as the cache will be very hard to find.
maximises choice but minimizes the decisions needed
