How To Build a Homebrew PS3 Cluster Supercomputer 211

Posted by timothy from the slot-a-tab-b dept.
eldavojohn writes "UMass Dartmouth Physics Professor Gaurav Khanna and UMass Dartmouth Principal Investigator Chris Poulin have created a step-by-step guide designed to show you how to build your own supercomputer for about $4,000. They are also hoping that by publishing this guide they will bring about a new kind of software development targeting this architecture & grid (I know a few failed NLP projects of my own that could use some new hardware). If this catches on for research institutions it may increase Sony's sales, but they might not be seeing the corresponding sale of games spike (where they make the most profit)."

Researchers Getting the Lead Out of Electronics 178

Posted by samzenpus from the space-age-polymers dept.
alphadogg writes "Researchers at the University of Maryland say they have discovered a material to replace lead, a potential environmental hazard, in electronics products. The material, bismuth samarium ferrite (BSFO), was found by researchers in the university's A. James Clark School of Engineering. It can be used in products such as biomedical imaging devices and inkjet printers, and if implemented commercially could keep lead out of landfills and the ecosystem, they say. While manufacturers have developed replacements for lead in many products, until now no commercial replacement existed for lead zirconate titanate (PZT) — the material of choice for transducers, actuators, sensors and microelectromechanical systems used in common electronic devices, the university says."

This is so unbelievably wrong. You get so much more calories per square foot growing vegetables than meat.

"The meat-based food system requires more energy, land, and water resources than the lactoovovegetarian diet. In this limited sense, the lactoovovegetarian diet is more sustainable than the average American meat-based diet." http://www.ajcn.org/cgi/content/full/78/3/660S

Verizon To Charge Content Providers $.03 Per SMS 260

Posted by timothy from the but-there's-no-penny-slot dept.
An anonymous reader writes "It appears that Verizon is going to start double-dipping by charging both consumers AND content providers for SMS text messages. Verizon has informed content partners that it will levy a $.03 charge for messages sent to customers, effective November 1. From RCRWireless: 'Countless companies could be affected by the new fee, from players in the booming SMS-search space (4INFO, Google Inc. and ChaCha) to media companies (CNN, ESPN and local outlets) to mobile-couponing startups (Cellfire) to banks and other institutions that use mobile as an extension of customer services.'"

Ford To Introduce Restrictive Car Keys For Parents 1224

Posted by kdawson from the no-you-cannot-borrow-my-keys dept.
thesandbender writes "Ford is set to release a management system that will restrict certain aspects of a car's performance based on which key is in the ignition. The speed is limited to 80, you can't turn off traction control, and you can't turn the stereo up to eleven. It's targeted at parents of teenagers and seems like a generally good idea, especially if you get a break on your insurance." The keys will be introduced with the 2010 Focus coupe and will quickly spread to Ford's entire lineup.

Users Report Faulty WPA In 2nd-Gen IPod Touch 188

Posted by kdawson from the soft-touch dept.
jesuscash writes "It seems early adopters of the new iPod Touch are out of luck when they bring it home and attempt to connect it to their WPA/WPA2 secured network. Reading this Apple forum thread shows that many tests with different configurations show a no-go on WPA. Some of the last entries give the best clue, revealing a 'received deauthentication' error in their router logs. Apple has yet to respond."

New Study Shows Solar System Is Uncommon 290

Posted by kdawson from the isn't-that-special dept.
Iddo Genuth writes "Research conducted by a team of North American scientists shows our solar system is special, contrary to the accepted theory that it is an average planetary system. Using computer simulations to follow the development of planets, it was shown that very specific conditions are needed for a proto-stellar disk to evolve into a solar system-like planetary system. The simulations show that in most cases either no planets are created, or planets are formed and then migrate towards the disk center and acquire highly elliptical orbits." The research was published in Science magazine; here's the paper on ArXiv (PDF).
