Traffic-Flow Algorithm Can Reduce Fuel Consumption 328

thecarchik writes "New projects from German automakers Audi and BMW promise to ease congestion simply by looking at traffic signals and driving style, in an effort to smooth the flow of traffic. Through a test course in Munich, vehicles were able to post phenomenal fuel efficiency gains simply by adjusting the timing of traffic lights depending on traffic volume — to whatever speed provides a so-called 'green wave' of four or more synchronized signals."

Submission + - Linux Driver Violates BSD License (undeadly.org)

bsdphx writes: After years of encouragement from the OpenBSD community for others to use Reyk Floeter's free atheros wireless driver, it seems that the Linux world is finally listening. Unfortunately, they seem to think that they can strip the BSD license right out of it.

The Fallacy of Hard Tests 404

Al Feldzamen writes in with a blog post on the fallacious math behind many specialist examinations. "'The test was very hard,' the medical specialist said. 'Only 35 percent passed.' 'How did they grade it?' I asked. 'Multiple choice,' he said. 'They count the number right.' As a former mathematician, I immediately knew the test results were meaningless. It was typical of the very hard test, like bar exams or medical license exams, where very often the well-qualified and knowledgeable fail the exam. But that's because the exam itself is a fraud."

Does Sprawl Make Us Fat? 659

Ant writes "A Science News article talks about the relationship between city design and health. New cross-disciplinary research is exploring whether urban sprawl makes us soft, or whether people who don't like to exercise move to the sprawling suburbs, or some combination of both." From the article: "So far, the dozen strong studies that have probed the relationships among the urban environment, people's activity, and obesity have all agreed, says Ewing. 'Sprawling places have heavier people... There is evidence of an association between the built environment and obesity.' ... However, University of Toronto economist Matthew Turner charges that 'a lot of people out there don't like urban sprawl, and those people are trying to hijack the obesity epidemic to further the smart-growth agenda [and] change how cities look.' ... 'We're the only ones that have tried to distinguish between causation and sorting... and we find that it's sorting,' [says Turner]. 'The available facts do not support the conclusion that sprawling neighborhoods cause weight gain.'"

Inside MySpace.com 250

lizzyben writes "Baseline is running a long piece about the inner workings of MySpace.com. The story chronicles how the social networking site has continuously upgraded its technology infrastructure — not entirely systematically — to accommodate more than 26 million accounts. It was a rocky road and there are still hiccups, several of which writer David F. Carr details here." From the story: "MySpace.com's continued growth flies in the face of much of what Web experts have told us for years about how to succeed on the Internet. It's buggy, often responding to basic user requests with the dreaded 'Unexpected Error' screen, and stocked with thousands of pages that violate all sorts of conventional Web design standards with their wild colors and confusing background images. And yet, it succeeds anyway."

Apple and Windows Will Force Linux Underground 554

eastbayted writes "Tom Yager at InfoWorld predicts: 'At the end of the decade, we'll find that Apple UNIX has overtaken commercial Linux as the second most popular general client and server computing platform behind Windows.' That's not a gloom-and-doom omen for the ever-popular Linux kernel, though, he stresses. While Apple and Microsoft will grapple for dominance of client and server spaces, Linux will be 'the de facto choice for embedded solutions.' And by 'embedded,' Yager means 'specialized.' With a push of a button and a flip of switch, he predicts, you'll be able to create a configured database and a mated J2EE server — all thanks to Linux."

The Dangers of Open Content 240

gihan_ripper writes "Recently released open movie Elephants Dream found itself in hot water with Catalonians after accidentally using an offensive word instead of 'Català' in the subtitle menu. The cause? Designer Matt Ebb had used Wikipedia to look up the Catalan word for Catalan on a day when the entry had been vandalized. He writes about this experience on the Elephant Dream blog. We may have scoffed at John Seigenthaler over his criticisms of Wikipedia, but it gives us pause for thought when we to heavily on Wikipedia."

AppleBerry Predicted? 181

dr_fatty writes "The Globe and Mail is reporting that analyst Peter Misek, who predicted a partnership between Research in Motion and IBM, is now predicting a partnership between Apple and Rim. The predicted result? The AppleBerry. 'Such a deal would have huge merit because each company lacks what the other provides. RIM wants a firm foothold in the consumer market and Apple doesn't have a presence in the booming wireless data sector, he said.'"

Creative Sues Apple 423

E IS mC(Square) writes "Looks like Apple's legal problems are not yet over. ZDNet reports that Creative has sued Apple over their iPod interface. From the article: 'Creative Technology said Monday that it has filed two legal actions against Apple Computer, charging the popular iPod infringes on its patented technology. ... In both cases, Creative says that the iPod and iPod Nano infringe on a patent the company has for the interface in its Zen media player, a patent granted last August.'"

Pr0n's Effect On Society 1021

Rytis writes "An article at the Financial Times is analysing the growing impact of internet pornography, the phenomena itself and the problems that it causes to our society. Surveys within Great Britain have shown that more than a half of 9-19 years olds have seen pornography online. From the article: 'To some men, Haynes argues, clicking on porn is simply a way to pass the time. It's a hobby. Once they'd idly play solitaire; now they idly click on a porn site. Others, though, succumb to addiction: Most addictions are to do with internal emptiness, wanting to fill up dead space, and addiction is always destructive.'"

US Government Seeks Open-Source Translation 309

valdean writes "The Boston Globe is reporting that last week the United States Government began publishing captured Iraqi documents on the web in order to harness the translating talents of the bilingual public. The article calls it 'the same open source principle' that created Linux. Check out the Foreign Military Studies Office's document portal."

Suing Google Over Pagerank 427

Yardboy wrote in to tell us about a story from Reuters describing a lawsuit by parental advice company Kinderstart.com against Google for 'charging it unfairly deprived the company of customers by downgrading its search-result ranking without reason or warning.' Kinderssart claims Google is responsible for 'a "cataclysmic" 70 percent fall in its audience -- and a resulting 80 percent decline in revenue.' I guess the courts will now decide: Can google taketh what they giveth?

Futurama Returns 386

riflemann writes "Another 26 episodes of Futurama will shortly go into production! This news comes from none other than Billy West (voice of Fry) himself, in a short post to his own message board. No further details are available, except that it's likely to be on TV, not straight to DVD." The best news is that means fresh quotes for slashteam to hide in the source code.

The Mythbusters Construct a Kit Bot 148

A reader wrote in to mention a writeup of a really great Mythbusters project. Hyneman, Savage, and Imahara went out and purchased a 'Vex' robot kit from RadioShack, and constructed the bot to see what it was like. They were pleasantly surprised. From the article: "Jamie Hyneman: I must admit I was expecting to turn up my nose at a do-it yourself robotics kit from Radio Shack. But guess what? The VEX System kicks butt. In a total of about 12 person-hours, Adam Savage and Grant Imahara (my cohosts on MythBusters) and I were able to build a functional, if somewhat basic, prototype equivalent of an iRobot's PackBot."
