Submission + - NVidia Cripples PhysX "Open API" 1

An anonymous reader writes: In a foot-meet-bullet type move, NVidia is going to disable PhysX engine if you are using a display adapter other than one that came from their company. This despite the fact that you may have an NVidia card on your system specifically to do this type of processing. "For a variety of reasons some development expense, some quality assurance and some business reasons Nvidia will not support GPU accelerated PhysX with Nvidia GPUs while GPU rendering is happening on non-Nvidia GPUs." Time to say hello to Microsoft dx physics or Intel's Havok engine.

Submission + - Microsoft releases new OS attempt, Barrelfish (networkworld.com)

Julie188 writes: "You've likely heard of Microsoft's next-gen operating system projects Midori and Singularity, but earlier this month researchers released a prototye for another OS, code-named Barrelfish. Barrelfish is an OS written specifically for multicore environments. It hopes to improve the performance of boxes with such chips by creating a network bus, if you will, between cores. Today such systems tend to share resources like memory. As demand increases, performance of the box decreases as shared resources don't scale well. Barrelfish instead passes messages between cores on its bus, and reportedly uses a database-like approach to keep track of the hardware available."

AMD Radeon HD 5870 Adds DX11, Multi-Monitor Gaming 195

Vigile writes "Few people will doubt that PC gaming is in need of a significant shot in the arm with the consistent encroachment of consoles and their dominating hold on developers. Today AMD is releasing the Radeon HD 5870 graphics card based on the Evergreen-series of GPUs first demonstrated in June. Besides offering best-in-class performance for a single-GPU graphics board, the new card is easily the most power efficient in terms of idle power consumption and performance per watt. Not only that, but AMD has introduced new features that could help keep PC gaming in the spotlight, including the first DirectX 11 implementation and a very impressive multi-monitor gaming technology, Eyefinity, which we discussed earlier this month. The review at PC Perspective includes the full gamut of gaming benchmarks in both single- and dual-GPU configurations as well as videos of Eyefinity running on three 30" displays."

Early Details On Courier, Microsoft's Take On a Tablet 175

rbanffy points out an article on Gizmodo about Courier, a tablet (or more accurately, a booklet) in development at Microsoft. "The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre." A concept video shows off the ability to use the two different screens for separate purposes, like browsing the web or a photo album on the left and using the right as a notepad or workspace.

Submission + - First public sighting of Larrabee (pcpro.co.uk)

darien writes: "Intel has given the first public demo of Larrabee, its x86-based multi-core graphics system, at IDF in San Francisco. The demo showcased real-time ray traced reflections, but looked distinctly underwhelming compared to what's possible with current GPU technology — and no one was willing to talk about the technical details."

Submission + - SPAM: Court to scammer: Give up your house or go to jail 1

coondoggie writes: "Too many online scammers get away with what amounts to a wrist slap but a case if Las Vegas this week seems to be heading the right direction at least.

According to the Federal Trade Commission, a business opportunity scammer has been held in contempt for the second time by a federal court and ordered to turn over the title of his home in Las Vegas or face jail time.

The court found that the operator of the scam, Richard Neiswonger, failed to deliver marketable title to his home, in violation of a previous court order entering a $3.2 million judgment against him, the FTC stated. The FTC charged that the defendant deceived consumers with false promises that they could make a six-figure income by selling his "asset protection services" to those seeking to hide their assets from potential lawsuits or creditors.

US Supercomputer Lead Sparks Russian Govt's Competitive Drive 74

CWmike writes "Russia's launch of Sputnik in 1957 triggered a crisis of confidence in the US that helped drive the creation of a space program. Now, Russia is comparing the US's achievements in supercomputing with theirs, and they don't like what they see. In a speech on Tuesday, Russia's President, Dmitry Medvedev, criticized his country's IT industry almost to the point of sarcasm for failing to develop supercomputing technology, and urged a dramatic change in Russia's use of high-performance computing. Medvedev, at the opening address of a Security Council Meeting on Supercomputers in Moscow, told attendees that 476 out of the 500 supercomputers on the Top500 list were manufactured in the United States. 'Therefore, in general, our situation is very difficult,' he said."

Submission + - Are Compact Fluorescents Really Green? (inhabitat.com)

Mike writes: "Ever since An Inconvenient Truth debuted houses, businesses, and even entire nations have switched from incandescent bulbs to more energy-efficient compact fluorescent lamps. However concerns have grown recently over the toxic mercury contained within CFLs, and competing technologies like LEDs and OLEDs are casting a shadow over the bulb's eco merits. An in-depth report explores the current state of the debate and where the future of energy efficient lighting is heading."

Submission + - Transparent aluminium is 'new state of matter' (physorg.com) 2

Professor_Quail writes: Oxford scientists have created a transparent form of aluminum by bombarding the metal with the world's most powerful soft X-ray laser. 'Transparent aluminum' previously only existed in science fiction, featuring in the movie Star Trek IV, but the real material is an exotic new state of matter with implications for planetary science and nuclear fusion.

Submission + - Music industry thrives in an era of file sharing (zeropaid.com)

levicivita writes: "Zero Paid analyzes a recent study "Adding up the Music Industry for 2008" by "Will Page, the Chief Economist for PRS for Music, a UK-based royalty collecting group for music writers, composers, and publishers" which found that "total music industry revenues are up 4.7% since 2007 [which] corroborates what many studies have shown, that P2P actually increases music consumption." How is that possible? Will reports that "sales of recorded music fell 6% [...], digital was up 50% while physical dropped 10%, but concert ticket sales grew by 13%.""

Submission + - People Emit Visible Light (aol.com)

Anonymous Coward writes: "The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists now reveal. Japanese researchers have shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive. In fact, virtually all living creatures emit very weak light, which is thought to be a byproduct of biochemical reactions involving free radicals."

Submission + - New C++ standard delayed until 2010 or later

wandazulu writes: At the end of an article written by the creator of C++ where he talks about removing a feature from the new C++ standard, he drops a bombshell: The new C++ standard (typically referred to as C++0x) has been delayed until 2010 or later. What does this mean? No new C++ features like threads, proper enum classes, or hash tables. C++0x is dead, long live C++1x!.

MIT Electric Car May Outperform Rival Gas Models 457

alphadogg writes "Inside a plain-looking garage on the Massachusetts Institute of Technology's campus, undergraduate Radu Gogoana and his team of fellow students are working on a project that could rival what major automobile manufacturers are doing. The team's goal is to build an all-electric car with similar performance capabilities of gasoline-only counterparts, which includes a top speed of about 161 kph, a family sedan capacity, a range of about 320 kilometers and the ability to recharge in about 10 minutes. They hope to complete the project, which they chronicle on their blog, by the third quarter of 2010. Each member of MIT's Electric Vehicle Team works almost 100 hours a week on the project they call elEVen. 'Right now the thing that differentiates us is that we're exploring rapid recharge,' Gogoana said during an interview. He said that many of today's electric vehicles take between two to 12 hours to recharge and he doesn't know of any commercially available, rapidly recharging vehicles."

Bethesda Speaks On Gamebryo Engine, Final Fallout 3 DLC 101

PsxMeUP writes "Game Observer conducted an interview with Ashley Cheng, Production Director at Bethesda. He answered questions about the Gamebryo engine, why they prefer it over other engines and the advantages it presented while making Fallout 3. Cheng also talks a bit about what inspired their designers while making Fallout 3 and what is in store for the PS3. Apparently, much of the team has read Cormac McCarthy's The Road, which inspired the look and story of Fallout 3. Bethesda, according to Cheng, will never create a game like Final Fantasy because the Gamebryo engine is better at handling 'open ended worlds ripe for exploration.'" Meanwhile, Bethesda's Jeff Gardiner spoke recently about the game's fifth and final DLC release, Mothership Zeta, which finds players aboard an alien spaceship in orbit. He said, "The player will have a handful of tasty alien technologies to play with. There are new fire arms and melee weapons, which will comprise the most powerful weaponry in the game."
