Victor wants to know how the Internet works and who owns it. The Internet is essentially a collection of networks. There's a great book about its foundation called Where Wizards Stay Up Late: The Origins Of The Internet by Katie Hafner. It was a project of DARPA which got computers and networks to talk to each other. So in essence, the Internet is merely a protocol, with individual networks owning each other. The wires between them, however, are owned by ISP companies.
DARPA, the Defense Advanced Research Projects Agency, held a challenge over the weekend that put humanoid robots to task. The robots were expected to drive and park a vehicle, open a door and walk through it, turn a valve handle one full rotation, use a power drill to cut a hole in a sheetrock wall big enough for a person to fit through, climb over and through rubble, climb a metal staircase, and then perform a surprise task. The robots were able to complete most of these objectives, but had some minor issues along the way.
