I am most thoroughly, indubitably nerdy Herein I discuss wardriving on the bus with my iPod Touch.→[More:]

The iPod Touch has a powerful wifi receiver and can detect networks quickly and at a great distance, even on a moving bus. What's more, the Touch remembers networks it's visited before and connects even more quickly.

The upshot is there are several points on my daily bus route where I can upload and download email at a red light or a bus stop.

Some of the wireless has a standard name; some are personalised. The wireless points are everywhere. Four out of five are locked at any given point.

Even the poorest of neighbourhoods has wireless internet, which is great. Other digital knowledge is turning up. Digital cameras, mobile phones and used computers, recycled at thrift shops and small computer stores, are the cause (along with pirated software and folk wisdom).

The charity shop that I run is one of the few in the area that sells electronic goods, and I really enjoy explaining them to people and helping them determine if the goods are right for them.
