The US Swim Team's Secret Weapon, Science 180

Posted by ScuttleMonkey on Friday August 15, 2008 @05:11PM from the but-not-chemistry dept.

Hugh Pickens writes "When American Swimmer Margaret Hoelzer goes for the gold tonight in the 200-meter backstroke, part of her success will be due to a new system developed by Tim Wei, a mechanical and aerospace engineer at Rensselaer Polytechnic Institute, that uses fluid dynamics to study human movement allowing scientists and coaches to study how fast and hard a swimmer pushes the water as he moves through it. 'Wei uses a tracking technique called digital particle image velocimetry, commonly used to measure the flow of small particles around an airplane or small fish or crustaceans in water.' Wei filtered compressed air in a scuba tank through a porous hose to create bubbles about a tenth of a millimeter in diameter. When an athlete swims through a sheet of bubbles that rises from the pool floor, a camera captures their flow around the swimmer's body and the images show the direction and speed of the bubbles, which Wei then translates into the swimmer's thrust using software that he wrote."

Comment Eliminate Component Based Pricing (Score 4, Insightful) 483

When traveling to California last year, that was one thing that I really didn't like - how prices are quoted exclusive of tax.

In Australia, the price quoted has to be the price that is paid by the consumer - the airline industry recently got into trouble for not doing this i.e advertising cheap fares exclusive of the fuel levy, tax and other surcharges.

In addition to this, the amount of tax that was charge very often ends up on the receipt so businesses can use it to calculate their GST credits etc

New Grads Shun IT Jobs As "Boring" 752

Posted by timothy on Tuesday June 24, 2008 @12:17PM from the work-from-home-chicks-dig-it dept.

whencanistop writes "Despite good job prospects, graduates think that a job in IT would be boring. Is this because of the fact that Bill Gates has made the whole industry look nerdy? Surely with so many (especially young) people being 'web first' with not just their buying habits, but now in terms of what they do in their spare time, we'd expect more of them to want to get a career in it?"

Griefers Assault Epileptics Via Message Board 621

Posted by kdawson on Saturday March 29, 2008 @05:05PM from the not-funny-mcgee dept.

An anonymous reader tips us to a story up at Wired reporting on what may be the first computer attack to inflict physical harm on victims. Last Saturday, griefers posted hundreds of bogus messages on the support forums of the nonprofit Epilepsy Foundation that used JavaScript and strobing GIFs to trigger migraines and seizures in users. For about 3% of the 50 million epileptics worldwide, flashing lights and colors can trigger seizures. "'I don't fall over and convulse, but it hurts,' says [an IT worker in Ohio]. 'I was on the phone when it happened, and I couldn't move and couldn't speak.' ... Circumstantial evidence suggests the attack was the work of members of Anonymous, an informal collective of griefers best known for their recent war on the Church of Scientology. The first flurry of posts on the epilepsy forum referenced the site EBaumsWorld, which is much hated by Anonymous. And forum members claim they found a message board thread — since deleted — planning the attack at 7chan.org, a group stronghold."

China Continues to Shut Down Video Sites 158

I Don't Believe in Imaginary Property writes "It's not just YouTube that's blocked in China. After the unrest in Tibet, at least 25 video sharing sites have been shut down and others have been penalized. While the Chinese government is not admitting that violence in Tibet had anything to do with it, they do have a sudden interest in strictly enforcing licensing restrictions that require video sharing websites to register with the government. Among other things, Chinese video sharing sites must promise not to show videos that inspire fear, contain pornography, or endanger national security."

Sequoia Vote Machine Can't Do Simple Arithmetic? 254

whoever57 writes "Ed Felten is showing a scan of the summary from a Sequoia voting machine used in New Jersey. According to the paper record, the vote tallies don't add up — the total number of Republican ballots does not match the number of votes cast in the Republican primary and the total number of Democratic ballots does not match the number of votes cast in the Democratic primary. Felten has a number of discussions about the problems facing evoting, up to and including a semi-threatening email from Sequoia itself." Update: 03/20 23:30 GMT by J : Later today, Felten added an update in which he analyzes Sequoia's explanation. He has questions, comments, and a demand.

Scientology Injunction Denied Against "Anonymous" 486

Posted by ScuttleMonkey on Saturday March 15, 2008 @03:26AM from the much-gnashing-of-teeth dept.

Anonymous writes "A circuit court judge has denied the Church of Scientology's second request for an injunction against protests by the internet group "Anonymous." The Church sought to prevent Anonymous from protesting on the birthday of the Church's leader, the late Ron L. Hubbard. The petition filed by the Church listed twenty-six individuals allegedly affiliated with Anonymous, but "accidentally" included others who merely work near the location of the first protests held in February and did not participate in them, such as a Starbucks employee. Furthermore, the Church failed to show that any of those listed actually committed any wrongdoing."

DOE Shines $14M on Solar Energy Research 164

Posted by samzenpus on Thursday March 13, 2008 @05:11AM from the government-heliotrope dept.

coondoggie writes "Eleven university solar research projects aimed at developing advanced solar photovoltaic (PV) technology manufacturing processes and products got a $14 million boost today from the Dept. of Energy. Photovoltaic-based solar cells convert sunlight directly into electricity, and are made of semiconductor materials similar to those used in computer chips. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity."

Unreal Creator Proclaims PCs are Not For Gaming 705

An anonymous reader writes "TG Daily is running an interesting interview with EPIC founder and Unreal creator Tim Sweeney. Sweeney is anyway very clear about his views on the gaming industry, but it is surprising how sharply he criticizes the PC industry for transforming the PC into a useless gaming machine. He's especially unhappy with Intel, which he says has integrated graphics chipsets that 'just don't work'."

Sun Is Porting Java To the iPhone 275

Posted by kdawson on Saturday March 08, 2008 @02:27PM from the who's-driving-now dept.

krquet notes an InfoWorld article on Sun's plans for the iPhone. After studying Apple's newly released SDK docs for 24 hours, Sun decided it was feasible to develop a JVM, based on Java Micro Edition, for both the iPhone and the iTouch. An analyst is quoted: "I think going forward, with the SDK, it takes out of Apple's control which applications are 'right' for the iPhone." The article doesn't speculate on how Apple might to react to such a loss of control. "Apple had not shown interest in enabling Java to run on the iPhone, but Sun plans to step in and do the job itself... The free JVM would be made available via Apple's App Store marketplace for third-party applications."

Iran May Shut Down Internet During Election 234

Posted by Zonk on Tuesday March 04, 2008 @11:43AM from the can't-stop-the-signal-mal dept.

daveschroeder writes "'The Iranian government might block private access to the Internet for the general legislative election on March 14, two Iranian news outlets reported Monday. In 2006, the authorities banned download speeds on private computers faster than 128 kilobytes per second. The government also uses sophisticated filtering equipment to block hundreds of Web sites and blogs that it considers religiously or politically inappropriate. Many bloggers have been jailed in the past years, and dozens of Web sites have been shut down.' It would appear that Iran's own government is more a threat to the nation's internet connectivity than the fragility of the undersea cable network."

Strict Order Boarding Would Get Planes in the Sky Faster 880

electrostatic writes "In a Nature.com oldie-but-goodie, a physicist says he has solved a problem that costs airlines millions every year: what is the quickest way to get passengers aboard an aircraft? Boarding is a serious issue for airlines, particularly those operating short flights that run several times a day, yet boarding times have steadily increased for decades. Back in 2005 Jason Steffen of the Fermilab in Batavia, Illinois said the method used by many airlines to this day is almost the worst. 'The best way to board, according to the researchers, would be a row-by-row, seat-by-seat, strict order. That would mean everyone lines up, row 25 first. I can't imagine fliers will go for that. Next best, they say, would be boarding all the window seats first, followed by those in the aisle. Obviously that's not practical, at least for couples or families traveling together.'"
