All GeForce 8 Graphics Cards to Gain PhysX Support 114

Posted by Soulskill
from the theoretical-physx dept.
J. Dzhugashvili writes "Nvidia completed its acquisition of Ageia yesterday, and it has revealed exactly what it plans to do with the company's PhysX physics processing engine. Nvidia CEO Jen-Hsun Huang says Nvidia is working to add PhysX support to its GeForce 8 series graphics processors using its CUDA general-purpose GPU (GPGPU) application programming interface. PhysX support will be available to all GeForce 8 owners via a simple software download, allowing those users to accelerate games that use the PhysX API without the need for any extra hardware. (Older cards aren't CUDA-compatible and therefore won't gain PhysX support.) With Havok FX shelved, the move may finally popularize hardware-accelerated physics processing in games."

+ - The Aerodynamics of Bicycle Racing

Submitted by
Ponca City, We Love You
Ponca City, We Love You writes "Nick Frey, the reigning national time-trial bicycle champion, is a mechanical and aerospace engineering major at Princeton who puts his knowledge to work in modifications to his racing bike. Once a bicycle is moving fast enough, nearly all the cyclist's strength goes into pushing aside air. Reducing that resistance by a relatively small amount can result in major increases in speed with minimal increased effort so one of Frey's innovations is enclosing his brake cables in a special housing shaped like an airplane wing that shields them from the wind, reducing the resistance on his bike. "It's like free speed," says Frey. "And in cycling, every second counts." Other improvements include the helmet he purchased to match his riding posture and the silicon gel between his wheel rims and tires that subtly changes the shape of his tires, making them more aerodynamic. Frey subjects his own performance to rigorous analysis and posts his training and performance results, along with details about various races, on his blog."

+ - Updated Top 100 Alternative Search Engines

Submitted by
ReadWriteWeb
ReadWriteWeb writes "In a follow-up to his Top 100 Alternative Search Engines article at the end of January, Search Engine Optimizer (SEO) Charles S. Knight has produced an updated list, featuring 32 new search engines. The criteria for the list is that search engines should exhibit superiority to Google — not as a whole, but in just one particular area. An example is "Search Engine of the Month" GoshME, a Meta-Meta-Search Engine which searches across a variety of specialized search engines and databases, then categorizes and filters the results.

Knight writes that 68 of the original 100 search engines are still firmly in the top 100, either because they have continued to improve (see Zuula), or because they have yet to be challenged (amongst the "Answers" search engines, only ChaCha uses paid guides, not volunteers or community members). This block of 68 search engines, says Knight, forms a sort of "core" representation of the new breed of alternative search engines."

An anonymous reader writes "After several hundred times of logging into your Mac you may be tired of looking at the same old login screen. Maybe you'd like to have a customized login screen for your school or employer's workstations. Forget the $10 programs that automate the process, we'll show you how to customize the login screen entirely on your own, for free. It's not as difficult as you might think, and it's a fun way to personalize your Mac a bit more. Be sure to check out the screenshot below for an example of the results. http://osxdaily.com/2007/02/22/customize-the-mac-o s-x-login-screen/"

Submitted by daria42
daria42 (866794) writes "The battle to control the virtualisation market has heated up with the launch of a white paper from VMware, which accuses Microsoft of anti-competitive practices. In language reminiscent of Microsoft's anti-trust battles in the US and its ongoing struggle with the European Union, VMware claimed that the software giant is "forcing [its] specifications and APIs on the industry", and "trying to restrict customers' flexibility and freedom to choose virtualisation software"."

Chuck speaks about building hardware, education, reverse engineering, open-source, and many other fascinating topics."

+ - Bacteria to protect against quakes

Submitted by
Roland Piquepaille
Roland Piquepaille writes "If you live near the sea, chances are high that your home is built over sandy soil. And if an earthquake strikes, deep and sandy soils can turn to liquid, with some disastrous consequences for the buildings sitting on them. But now, U.S. researchers have found a way to use bacteria to steady buildings against earthquakes by turning these sandy soils into rocks. Today, it is possible to inject chemicals in the ground to reinforce it, but this can have toxic effects on soil and water. On the contrary, this use of common bacteria to 'cement' sands has no harmful effects on the environment. But so far, this method is limited to labs and the researchers are working on scaling their technique. Here are more references and a picture showing how unstable ground can aggravate the consequences of an earthquake."
