If I understand correctly, a lack of DNS records for a domain doesn't mean it has no owner. Say I have registered example.com, but not yet given it a nameserver. Most ISP's DNS servers would (correctly) respond to requests for www.example.com with an NXDOMAIN. Comcast, however, would return an A record pointing to their own web server. Essentially, they are ignoring the fact that I have paid for the right to configure the domain as I see fit. Or am I missing something?

The Texas Petawatt Laser 174

Roland Piquepaille notes the hype surrounding what the University of Texas at Austin is calling the world's most powerful laser. During a tenth of a femtosecond this laser is 2,000 times more powerful than all the power plants in the US, and is brighter than sunlight on the surface of the Sun. On his own blog Roland points out that UT's is not the first petawatt laser; that distinction belongs to a system installed at Lawrence Livermore National Laboratory in 1996.

Old Subway Cars As Artificial Reef 169

Pickens writes "Hundreds of retired New York City subway cars are being sunk sixteen nautical miles off Delaware's Indian River Inlet and about 80 feet underwater, continuing the transformation of a barren stretch of ocean floor into a bountiful oasis, carpeted in sea grasses, walled thick with blue mussels and sponges, and teeming with black sea bass and tautog. 'They're basically luxury condominiums for fish,' says Jeff Tinsman, artificial reef program manager for the Delaware Department of Natural Resources and Environmental Control. Subway cars are roomy enough to invite certain fish, too heavy to shift easily in storms, and durable enough to avoid throwing off debris for decades. Tinsman particularly favors the newer subway cars with stainless steel on the outside to create reefs. 'We call these the DeLoreans of the deep,' he said. But success comes at a price because other states, seeing Delaware's successes, have started competing for the subway cars, which New York City provides free. 'The secret is out, I guess,' said Michael G. Zacchea, the MTA official in charge of getting rid of New York City's old subway cars."
