Submission + - PS3 Folding@home project gets Guinness record (news.com)

mytrip writes: "t's a small thing, but Sony got some good news today related to its troubled PlayStation 3 video game console. In fact, the system helped set a new Guinness World Record.

The record was set by Stanford University's Folding@home project, a distributed computing system utilizing PS3s among other computers, to help scientists study the effects of a process called "protein folding" on a series of serious diseases.

Well, Guinness has apparently certified the project as the world's most powerful distributed computing system. According to a release from Sony, Folding@home topped 1 petaflop last month, meaning that it surpassed a thousand trillion floating point operations per second. By comparison, the well-known SETI@home project has topped out, according to Wikipedia, at around 265 teraflops, or 265 trillion floating point operations a second."

Submission + - Canadian ISP Blocking Encrypted Email

An anonymous reader writes: Michael Geist reports that Rogers, one of Canada's largest ISPs, has implemented new technologies that may limit access to basic services such as email. The move comes as a result of Rogers packet shaping, which limits the bandwidth allocated to peer-to-peer applications. Many P2P apps now encrypt their data, so in response Rogers is simply degrading all encrypted traffic and in the process mistaking encrypted email traffic for BitTorrent traffic.
