Importantly, this looks to be a Facebook-specific implementation of Vanish, a project with the goal of making data "self-destruct" after a set period of time done by Roxana Geambasu and her colleagues at the University of Washington, linked here. They describe in their USENIX Security paper why encryption alone doesn't solve the problem.
Phew! Thank goodness I defended over the summer. Maybe I should register for a new number certifying I've read the new rules?
These are well-known techniques in the telephony world. AT&T has been using this for many years to combat telecom fraud; knowing who you call means that if you don't pay your bill but another phone number starts calling people in your circle of friends, they can identify that it's you making those calls. Communities of interest have also been examined in the context of IP networks and email. It's an interesting field of research and this seems like a novel analysis, though I'm sure they are doing something very similar within every carrier network.
BuR4N writes "The American movie industry today decided to take another stab at the people behind The Pirate Bay the Swedish newspaper "Dagens Nyheter" reports. The last time it was IFPI ( http://www.ifpi.org/ ) that sued and won the first round in the court, the verdict was much debated especially when details about the judge being member of organisations around the copyright lobby emerged. The Local (Swedish news in English) has a good summary of this new turn in The pirate bay story. http://www.thelocal.se/20954/20090728/"

If you're interested in theory, read up on the DIMACS group at Rutgers. They are very well regarded.
UPenn, Cornell, Stanford immediate come to mind if you're looking to play at the top level. Look at proceedings of the POPL and PLDI conferences to get a sense of what people are doing and where they are doing it.
One good book on investing is David Chilton's The Wealthy Barber. I recommend it.
sudnshok writes "Hasbrouck Heights (NJ) Library Director Michele Reutty is under fire for refusing to give police library circulation records without a subpoena. Her lawyer explained, 'Reutty did the right thing... At no time did Michele Reutty say to any police officer or anybody else that she would not give the information if it was properly requested.' However, borough labor lawyer Ellen Horn, who also represented the library trustees, said Reutty was 'more interested in protecting' her library than helping the police. 'It was an absolute misjudgment of the seriousness of the matter,' Horn said."
Sony has announced that their first model of Blu-Ray player will release in August, not later this month as originally announced. The BDP-SP1, retailing for $1000, will now ship on or about August 15th. Bad news for fans of the new format, and even worse news for the PS3. Since Sony's lackluster E3 showing, a string of bad news has seemed to conspire against the company's next-gen console. From the Gamers with Jobs article: "With the PS3's high-end model coming it at a whopping $400.00 less than a stand-alone Blu-Ray player, Sony needs to release these players as soon as possible. If they wait too long, the PS3 will begin looming on the horizon, causing even devout early adopters to question the intelligence of buying a stand-alone Blu-Ray unit. Sony also needs the largest possible installed base, come launch-time for the PS3. For the Blu-Ray player to be the PS3's version of the PS2's DVD player, casual technophiles need to be able to see the virtues of the Blu-Ray format. If there are few players, and few titles, this might not happen."
