Miscalculation Invalidates LHC Safety Assurances 684

KentuckyFC writes "In a truly frightening study, physicists at the University of Oxford have identified a massive miscalculation that makes the LHC safety assurances more or less invalid (abstract). The focus of their work is not the safety of particle accelerators per se but the chances of any particular scientific argument being wrong. 'If the probability estimate given by an argument is dwarfed by the chance that the argument itself is flawed, then the estimate is suspect,' say the team. That has serious implications for the LHC, which some people worry could generate black holes that will swallow the planet. Nobody at CERN has put a figure on the chances of the LHC destroying the planet. One study simply said: 'there is no risk of any significance whatsoever from such black holes.' The danger is that this thinking could be entirely flawed, but what are the chances of this? The Oxford team say that roughly one in a thousand scientific papers have to be withdrawn because of errors but generously suppose that in particle physics, the rate is one in 10,000."

A Cheap, Distributed Zero-Day Defense? 116

coondoggie writes "Shutting down zero-day computer attacks could be carried out inexpensively by peer-to-peer software that shares information about anomalous behavior, say researchers at the University of California at Davis.The software would interact with existing personal firewalls and intrusion detection systems to gather data about anomalous behavior, says Senthil Cheetancheri, the lead researcher on the project he undertook as a grad student at UC Davis from 2004 to 2007. He now works for SonicWall."

I've found that Synergy doesn't work correctly with the mouse look in WoW. It just spins the view around really fast and eventually settles on looking straight up - quite annoying. Keys & clicking on things work just find though.

Students Are Always Half Right In Pittsburgh 881

Pittsburgh Public Schools officials have enacted a policy that sets 50 percent as the minimum score a student can receive for assignments, tests and other work. District spokeswoman Ebony Pugh said, the 50 percent minimum gives children a chance to catch up and a reason to keep trying. If a student gets a 20 percent in a class for the first marking period, he or she would need a 100 percent during the second marking period just to squeak through the semester. The district and teachers union issued a joint memo to ensure staff members' compliance with the policy, which was already on the books but enforced only at some schools. At this rate, it won't be long before schools institute double extra credit Mondays and Fridays to ensure students don't take three day weekends.

Google Unsure About Letting Users Vote On Search 145

narramissic writes "Google began running a live test last year that lets people rank and remove search engine results and comment on them. Testers were presented with different variations of the experiment, which the company first publicly detailed about two weeks ago in an official blog posting. For example, in one version of the test, people can only remove results, while in another they can append comments that only they can see, said Google software engineer Matt Cutts. But while implementing these features permanently would be a major step for Google in giving more participation to its users, the company remains undecided. 'It's a really fun experiment. I can't say for sure whether it will go live for everybody because we're always running a ton of experiments. Only some of those, the ones that are being very successful, are launched live for everybody,' said Cutts. In the meantime, Google is collecting data that offers some interesting search quality insights."

Hit Man Email Scammer Back With a Vengeance 169

coondoggie writes "The online Hitman scammer, who threatens to kill recipients if they do not pay thousands of dollars to the sender, is still sending out thousands of emails and the FBI is again today warning users to ignore the spam and report any incidents to the Internet Crime Complaint Center. Two new versions of the scheme began appearing in July 2008, the FBI said. One instructed the recipient to contact a telephone number contained in the e-mail and the other claimed the recipient or a 'loved one' was going to be kidnapped unless a ransom was paid."

Adobe Flash Ads Launching Clipboard Hijack Attacks 353

bullyBEEF writes "Malicious hackers are using booby-trapped Flash banner ads to hijack clipboards for use in rogue security software attacks. In the Web attacks, which affect Mac, Windows, and Linux users running Firefox, IE, and Safari, bad guys are seizing control of the machine's clipboard (probably using the Flash command setClipboard) and inserting a hard-to-delete URL that points to a fake anti-virus program. A number of legitimate sites have been seen to host ads carrying the attack — including Newsweek, Digg, and MSNBC.com. Researcher Aviv Raff offers a harmless demo of how it's done."

Strange Ubuntu/Vista Compatibility Bug, Solved 140

Walter Vos writes "Since I've been running Vista and Ubuntu in dual boot with a shared FAT32 partition for my personal folders, I've been seeing some strange compatibility issues between these two operating systems. Somehow Vista locks the folders on the FAT32 partition that are used for folders like Documents, Downloads, etc. A blogpost I wrote gives a detailed description of the problem and a fix for it."

A Hidden Loop In the Carbon Cycle Discovered 310

Googlesaysmysiteisdangerousanditisn't! writes "A recent article in Science says that researchers in China and the US have found massive carbon uptake in the world's deserts. The effects of this are huge. 35% of the Earth's land surface is desert, and the uptake equates to 5.2 billion tons of carbon sequestered each year. This is more than half of the carbon released by humans. In these 'dry oceans,' the grains of sand allow the carbon dioxide to enter and react with alkaline soil to become carbonates. Another scientist suspects that biotic desert crusts, alkaline soils, and increased precipitation may be driving the uptake."

3D Printing For Everyone 183

mmacx writes "Technology Review has up an article about Shapeways, a new online rapid-prototyping service that allows users to upload digital designs which are then printed on 3-D printers and shipped back. A spinoff from Philips Research, the service gives small businesses, designers, artists, and hobbyists access to prototyping tools that were once available only to the largest corporations. The fee for a typical printed object is $50-$150. Their video shows the steps behind the process." We've been talking about 3D printing for years.

The War Against Virtual Beer Pong 368

Michelle Shildkret, 360i on behalf of TIME.com writes "JV Games was all set to release 'Beer Pong' for the Nintendo Wii when parents and lawmakers got a whiff, forcibly renaming the game to Pong Toss and filling its pixelated cups with water instead. But the game is still rated 'T' for teen, and anybody who encounters it will be able to draw clear conclusions as to its intended purpose (drink and get drunk)." Lesson: Don't play games that simulate drinking before you play games that simulate driving, or larceny.

Scrabulous Is Dead, Hasbro's Version Brain-Dead 395

eldavojohn writes "Sometime this morning, Facebook shut down Scrabulous to American and Canadian users. Scrabulous, we hardly knew ye." This is sadly unsurprising, now that Hasbro's finally taken legal action against the developers, after quite a few months of letting it go unmolested. Seems like they waited until there was an official Scrabble client available (also on Facebook), while the snappy and fuller-featured Scrabulous kept people interested in a 60-year-old board game. The official client, which is at least labeled a beta, is a disappointment. This is not a Google-style beta release, note: it's slow to load, confusing, and doesn't even offer the SOWPODS word list as an option, only the Tournament Word List and a list based on the Merriam-Webster dictionary. (Too bad that SOWPODS is the word list used in most of the world's English-speaking countries.) It also took several minutes to open a game, rather than the few seconds (at most) that Scrabulous took — it's pretty impressive, but not in a good way, that the programmers could extract that sort of performance from the combination of Facebook's servers and my dual-core, 2GHz+ laptop. The new Scrabble client has doodads like 3D flipping-tile animations, too, but no clear way to actually initiate the sample game that jamie and I have attempted to start. I hope that once we get past that obvious hurdle, we'll find there's a chat interface and game notebook as in Scrabulous, but my hopes are low.

Web-Crawling Program Spots Disease Outbreaks 52

no1home writes "There is a story at Discovery Channel's site about a new utility for mapping disease. The premise is to have bots crawl the web looking for stories about disease outbreaks and log them onto a map. '"We were originally thinking about how we could expand disease surveillance and pick up outbreaks earlier than traditional methods," said John Brownstein of Harvard Medical School and Children's Hospital Boston, who created HealthMap in September of 2006 with Clark Friefeld, a software developer at Harvard Medical School.' But then it was noticed by Google.org and has since grown into its own website, HealthMap Global disease alert map, and claims to be able to identify 95% of all disease outbreaks, some of them before WHO or CDC."
