geaux and other readers let us know that the new Top 500 Supercomputer list is out. The top two both break the Petaflops barrier: LANL's IBM "RoadRunner" and ORNL's Cray XT5 "Jaguar." (Contrary to our discussion a few days back, IBM's last-minute upgrade of RoadRunner salvaged the top spot for Big Blue. Kind of like bidding on eBay.) The top six all run in excess of 400 Teraflops. HP has more systems in the top 500 than IBM, reversing the order of the previous list. Both Intel and AMD issued press releases crowing over their wins, and both are correct — AMD highlights its presence in 7 of the top 10, while Intel boasts that 379 of the top 500 use their chips.

An anonymous reader writes "International Humanitarian Law professor Ludwig Braeckeleer thinks so. In an article published yesterday in the Korean newspaper OhMyNews, he reveals a discovery he made while researching a story on the bombing of Pan Am Flight 103 over Scotland. It turns out that a Wikipedia administrator named SlimVirgin is actually Linda Mack, a woman who as a young graduate in the 1980s was hired by investigative reporter Pierre Salinger of ABC News to help with the investigation. Salinger later came to believe that Mack was actually working for Britain's MI5 on a mission to investigate the bombing and to infiltrate and monitor the news agency. Shortly after her Wikipedia identity was uncovered, many of her edits to articles related to the bombing were permanently removed from the database in an attempt to conceal her identity. This discovery comes only months after another Wikipedia admin was caught lying about his credentials to the press. What can Wikipedia do about those who would use it for their own purposes?"
