So, if you are wondering what Coffee has to do with web cams, then you need to know this…
“In 1991, when the World Wide Web was a text-only hangout for science geeks, and the University of Cambridge in England didn’t even have its own Web server, the University of Cambridge Computer Laboratory’s sole coffee machine lived in the hall outside a 15-member lab called the Trojan Room. Several members of the Lab’s “coffee club,” however, resided elsewhere in the building and had to negotiate several flights of stairs to reach the coffeepot. Their trips were often in vain, though, since the hackers from the Trojan Room tended to guzzle the fresh coffee first. Caffeine-starved but undeterred, the remote club members built the world’s first networked camera.”
