Fatal Flaw Discovered In Invisibility Cloaks 255

KentuckyFC writes "Carpet cloaks took the world by storm last year because they were the first devices to hide objects at optical frequencies. The idea is that a thin layer of dielectric material placed on a surface can make light look as if it is reflecting off the original surface. In other words, the layer is invisible and anything embedded within it is invisible too. This trick is like hiding something under a carpet, hence the name. Carpet cloaks are relatively easy to make because the dielectric material does not need to be specially constructed to steer light in special ways; physicists call this an isotropic material. Now a group at MIT has shown that isotropic carpet cloaks have a fatal flaw. When viewed at an angle, the carpets don't hide objects at all. Instead, they simply shift their position by about the same distance as they are high. So when viewed from an angle of 45 degrees, an object 0.2 units high is shifted to one side by a distance of 0.15 units, says the team. That's a serious limitation for carpet cloaks."

Network Solutions Sites Hacked Again 68

CWmike writes "A week after Web hosting company Network Solutions dealt with a large-scale infection of WordPress-driven blogs, the company acknowledged that other sites it hosts have been compromised. 'We have received reports that Network Solutions customers are seeing malicious code added to their websites and we are really sorry for this experience,' said spokesman Shashi Bellamkonda in a blog post. 'At this time, since anything we say in public may help the perpetrators, we are unable to provide details.' Securi Security Labs said on Sunday that at least 50 sites hosted by Networks Solutions had been hacked, and that malicious JavaScript injected into those sites was redirecting unsuspecting users to a Ukrainian attack server. The same server was involved in the earlier attacks against Network Solutions-hosted blogs. According to the StopMalvertising blog, the attacks planted a rogue IFRAME on the hacked sites to shunt users to the attack server. That server then launches multiple exploits, including an attack kit of ActiveX exploits and three more leveraging Adobe Reader vulnerabilities, against visiting PCs. Several browsers, including IE8, Chrome and Firefox, display warnings when users are redirected to the attack site."

EU Piracy Estimates — Just How Inaccurate? 124

Last week we discussed news that a US government report questioned the reliability of piracy statistics from the media industry. Reader superapecommando sends in a follow-up written by Glyn Moody that examines a similar problem in Europe. Quoting: "As far as I know, no similar analysis has been carried out for European reports. So I thought it might be interesting to look at one particular European report on the subject — not least because I've heard that its findings influenced some of the MPs voting on the Digital Economy Act. ... the net result of this 68-page report, with all of its tables and detailed methodology, is that four out of the top five markets used for calculating the overall piracy loss in Europe draw on figures supplied by the recording industry itself. Those apparently terrifying new figures detailing the supposed loss of money and jobs due to piracy in Europe turn out to be little more than a re-statement of the industry's previous claims in a slightly different form. As a result, as little credence can be placed in the report as in those criticised by the US GAO."

Why Computer Science Students Cheat 694

alphadogg writes "Enrollment in undergraduate computer science courses is at an all-time high at colleges nationwide. But this trend that's been hailed by the US tech industry has a dark side: a disproportionate number of students taking these courses are caught cheating. More students are caught cheating in introductory computer science courses than in any other course on campus, thanks to automated tools that professors use to detect unauthorized code reuse, excessive collaboration, and other forbidden ways of completing homework assignments. Computer science professors say their students are not more dishonest than students in other fields; they're just more likely to get caught because software is available to check for plagiarism. 'The truth is that on every campus, a large proportion of the reported cases of academic dishonesty come from introductory computer science courses, and the reason is totally obvious: we use automated tools to detect plagiarism,' explains Professor Ed Lazowska, chair of computer science and engineering at the University of Washington. 'We compare against other student submissions, and we compare against previous student submissions and against code that may be on the Web. These tools flag suspicious cases, which are then manually examined.'"

US House Passes Ban On Caller ID Spoofing 171

smarek writes "The 'Truth in Caller ID Act' passed the US House of Representatives on Wednesday. The legislation is trying to outlaw Caller ID spoofing. In some cases, this spoofing has led to individuals giving out information that has led to identity theft. Last year the NYPD discovered over 6,000 victims of Caller ID spoofing, who together lost a total of $15 million. A companion bill has already been passed by the Senate, and the two are on their way to 'informal conference to reconcile any differences.' The bill that results will most likely pass." PCWorld's coverage notes that callers will still be able to block their information entirely, and that the bill may have negative consequences for legitimate phone-related services, such as Google Voice.

Palm WebOS Hacked Via SMS Messages 99

gondaba writes "Security researchers at the Intrepidus Group have hacked into Palm's new WebOS platform, using nothing more than text messages to exploit a slew of dangerous web app vulnerabilities. The white hat hackers found that the WebOS SMS client did not properly perform input/output validation on any SMS messages sent to the handset, leading to a rudimentary HTML injection bug. Coupled with the fact that HTML injection leads directly to injecting code into a WebOS application, the attacks made possible were quite dangerous (especially considering they could all be delivered over an SMS message)."

George Washington Racks Up 220 Years of Late Fees At Library Screenshot-sm 146

Everyone knows that George Washington couldn't tell a lie. What you probably didn't know is that he couldn't return a library book on time. From the article: "New York City's oldest library says one of its ledgers shows that the president has racked up 220 years' worth of late fees on two books he borrowed, but never returned. One of the books was the 'Law of Nations,' which deals with international relations. The other was a volume of debates from Britain's House of Commons. Both books were due on Nov. 2, 1789."

Why Aren't SSD Prices Going Down? 249

Lucas123 writes "NAND flash memory makers took an economic beating from 2007 through the first quarter of 2009 due to supply outstripping demand. During that time, solid state drives dropped in price 60% year over year. But after the economic meltdown, fabricators pulled back on production and investment in new facilities and the price of SSDs have remained flat or increased over the past year, and that is not expected to change until 2011. Until that time, SSDs remain 10x more expensive than hard disk drives. SSD vendors, however, are using a few tricks to get sales up, including selling lower-capacity boot drives that hit a sweet spot in the techie/gamer market."

Cows On Treadmills Produce Clean Power For Farms 640

separsons writes "William Taylor, a farmer in Northern Ireland, recently developed the Livestock Power Mill, a treadmill for cows. Taylor uses the device to generate clean, renewable power for his farm. Cows are locked into a pen on top of a non-powered, inclined belt. The cows' walking turns the belt, which spins a gearbox to drive a generator. One cow can produce about two kilowatts of electricity, enough energy to power four milking machines. It may seem like a kooky idea, but Taylor could be onto something: According to his calculations, if the world's 1.3 billion cattle used treadmills for eight hours a day, they could provide six percent of the world's power!"

This Is Apple's Next iPhone 492

An anonymous reader writes "There has been some speculation about it. Not anymore: 'This is Apple's next iPhone. It was found lost in a bar in Redwood City, camouflaged to look like an iPhone 3GS. We got it. We disassembled it. It's the real thing, and here are all the details.' Judging by Gizmodo's reaction, it looks like a winner."

In Defense of Jailbreaking 405

Keith found a nice manifesto saying "There's a trend that's been disturbing me lately. When the topic of modding or jailbreaking comes up — say, in the wake of the iPad announcement, or Sony's restrictive PS3 update — there is an outcry. Who am I to tell Apple what's best for their devices?"

Life Recorder 347

Bruce Schneier writes "In 2006, writing about future threats on privacy, I described a life recorder: A 'life recorder' you can wear on your lapel that constantly records is still a few generations off: 200 gigabytes/year for audio and 700 gigabytes/year for video. It'll be sold as a security device, so that no one can attack you without being recorded."

Wisconsin Designates State Microbe Screenshot-sm 102

Hugh Pickens writes "The NY Times reports that state legislators in Wisconsin raced against the clock to pass a bill designating Lactococcus lactis as Wisconsin's official state microbe. 'The first time I heard the idea, I thought, I've got more important things to do than spending my time honoring a microbe,' says Gary Hebl, a Democratic state representative who proposed the bill which, he says, would make Wisconsin the first state in the nation to grant such a designation, 'but this microbe is really a very hard worker,' added Hebl, referring to the bacterium supported by the Department of Bacteriology at UW — Madison used to make cheddar, Colby, and Monterey Jack cheese. The proposal faced only one detractor in committee ('the opponent was clearly lactose-intolerant,' says Hebl), and there was no sign of a last-minute campaign from other bacteria, so by evening, the Assembly had approved the measure, 56 to 41. In case there were any doubts about Wisconsin's priorities, a separate bill also awaits consideration in Madison, declaring cheese Wisconsin's state snack."

Volcanic Ash Heading Towards North America 338

chocomilko writes "St. John's International Airport, the easternmost airport in Canada, has begun canceling flights due to worries of ash from Iceland's Eyjafjallajokull volcano, leaving travelers stranded after the weekend's Juno awards festival. Early reports stated that there was a 30% chance ash would reach the island by early Monday; Air Canada has issued an all-day travel advisory. A thick blanket of fog currently covering the city isn't helping matters, either."

Towards an Open Geolocation Database 74

theodp writes "With the location land rush in full swing, TechCrunch's Erick Schonfeld declares it's time for an open database of places and calls on the Big Dogs of location — Twitter, Google, Foursquare, Gowalla, SimpleGeo, Loopt, Citysearch, et al. — to make it so. An open database that maps latitude and longitude coordinates to businesses, points of interest, and even people's homes should just be part of the basic fabric of the mobile Web. Foursquare CEO Dennis Crowley was enthusiastic about the idea (in a standing-up-at-a-cocktail-party sort of way), says Schonfeld, while Twitter founder Jack Dorsey was a little bit more lukewarm and cautious. Time for Larry and Sergey to invite the Families to a sit-down at 37.423021,-122.083739?"
