An anonymous reader writes "Peter Jansen, a PhD student and member of the RepRap community, has constructed a working prototype of an inexpensive table-top laser cutter built out of old CD/DVD drives as an offshoot of his efforts to design an under $200 open-source Selective Laser Sintering (SLS) 3D printer. Where traditional laser cutters use powerful, fixed-focus beams, this new technique dynamically adjusts the focal point of the laser using a reciprocating motion similar to a reciprocating saw, allowing a far less powerful and inexpensive laser diode to be used. The technique is currently limited to cutting black materials to a depth of only a few millimeters, but should still be useful and enabling for Makers and other crafters. The end-goal is to create a hybrid inexpensive 3D printer that can be easily reconfigured for 2D laser cutting, providing powerful making tools to the desktop."

I Don't Believe in Imaginary Property writes "A Facebook employee has given a tell-all interview with some very interesting things about Facebook's internals. Especially interesting are all the things relating to Facebook privacy. Basically, you don't have any. Nearly everything you've ever done on the site is recorded into a database. While they fire employees for snooping, more than a few have done it. There's an internal system to let them log into anyone's profile, though they have to be able to defend their reason for doing so. And they used to have a master password that could log into any Facebook profile: 'Chuck Norris.' Bruce Schneier might be jealous of that one."
Probably was a former employee who did the job. At work we always joke to make a backdoor, ready to delete all backups in case we get fired. Unfortunately we have fireproof safes and off-site backups...

Slatterz writes "Apple co-founder Steve Wozniak, better known in the industry as 'Woz,' believes that the iPod is on its way out and has revealed his discomfort with some aspects of the iPhone. Wozniak said that the iPod has had a long time as the world's most popular media player, and that it will fall from grace due to oversupply. Wozniak also commented on the iPhone's proprietary nature and locked service provider, and compared it to Google's open Android platform. 'Consumers are not getting all they want when companies are very proprietary and lock their products down,' he said. 'I would like to write some more powerful apps than what you're allowed.'"
GogglesPisano writes "UK geneticist Steve Jones gave a presentation entitled Human Evolution Is Over. He asserts that human beings have stopped evolving because modern social customs have lowered the age at which human males have offspring, which results in fewer of the mutations necessary to drive evolutionary change. Apparently the fate of our species now depends upon older guys hooking up with younger woman. I, for one, welcome this development."
chirone writes: President Hugo Chavez has announced that Venezuela's official time will be put ahead by half an hour starting January 1. "Its about the metabolic effect, where the human brain is conditioned by sunlight," Chavez said in a rambling, seven hour discussion on his radio show "Alo, Presidente" with Science and Technology Minister Hector Navarro.
