Duke Univ. Device Converts Stray Wireless Energy Into Electricity For Charging 216

Lucas123 writes "Engineers at Duke University say they've constructed a device that can collect stray wireless signals and convert them into energy to charge batteries in devices such as cell phones and tablets. The WiFi collection device, made of cheap copper coils and fiberglass, can even aggregate energy from satellite signals and sound waves (abstract). The researchers created a series of five fiberglass and copper energy conductors on a circuit board, which was able to convert microwaves into 7.3V of electrical energy. By comparison, Universal Serial Bus (USB) chargers for small electronic devices provide about 5V of power. The device, the researchers say, is as efficient as solar cells with an energy conversion rate of 37%."

How could anyone ever not get it?

A space-warring world forcibly united under a pax (versus bugs) (US-)americana, kept in check through brainwashing highschools (with a nod to Pink Floyd) and psi-ops staring at no goats at all, as well as gamified, interactive global military-state television (nicely imagined when few people had ever seen such things, Fox, or even always-on internet) - full of overidentification that probably even North Korea would recognize&ban, and not-too-subtle references to world events, history and plenty of other notably (anti-)war movies...

The big mistake (like for Highlander) was ever making sequels of it.

Stephen Elop Would Pull a Nokia On Microsoft 292

Nerval's Lobster writes "A new Bloomberg report suggests that Stephen Elop, who's apparently on the short list of candidates to replace Steve Ballmer as Microsoft's CEO, would eliminate company projects such as Xbox and Bing while focusing resources on Office. Before he left Microsoft to join Nokia, Elop headed Microsoft's Business Division, so it's no surprise he'd want to focus on Office and the company's other, highly profitable enterprise software. But as head of Nokia, Elop made similarly bold strategic realignments that, while they probably looked good on paper, didn't quite work out. Specifically, Elop decided to abandon Nokia's popular homegrown operating systems, including Symbian, in favor of Microsoft's Windows Phone. That caused Nokia's share of the overall mobile-device market to dive into the single digits. At the time, Elop insisted he made the decision because Symbian and its ilk were incapable of competing in the broader market against Android and iOS; revelations by the Finnish media over the past few months, however, suggest that he'd been offered a generous cash incentive for selling off the company, which gives his 'strategic realignment' (which everyone knew would initially collapse Nokia's market-share, as its product pipeline emptied out) a whiff of self-interest. So while it's likely that a Microsoft run by Elop would make some decisive moves, his previous attempt at game-changing quickly transformed Nokia from a communications powerhouse into a second-tier competitor and (eventually) a Microsoft subsidiary. And by eliminating Bing and Xbox, Microsoft would be giving up completely on the search and gaming markets in favor of becoming more of an enterprise-centric company—something that could please analysts mostly interested in the company's bottom line, but basically an admission of defeat in the consumer realm."

Is Google Building a Floating Data Center In San Francisco Bay? 115

snydeq writes "CNET's Daniel Terdiman investigates an oversize secret project Google is constructing on San Francisco's Treasure Island, which according to one expert may be a sea-faring data center. 'Something big and mysterious is rising from a floating barge at the end of Treasure Island, a former Navy base in the middle of San Francisco Bay. And Google's fingerprints are all over it,' Terdiman writes. 'Whether the structure is in fact a floating data center is hard to say for sure, of course, since Google's not talking. But Google, understandably, has a history of putting data centers in places with cheap cooling, as well as undertaking odd and unexpected projects like trying to bring Internet access to developing nations via balloons and blimps.'"

LinkedIn's New Mobile App Called 'a Dream For Attackers' 122

An anonymous reader writes with a link to the New York Times' summary of a security and privacy disaster that's been inspiring angry posts on various social networks, including LinkedIn itself: "Security researchers are calling LinkedIn's new mobile app, Intro, a dream come true for hackers or intelligence agencies... Intro redirects e-mail traffic to and from users' iPhones and iPads through LinkedIn's servers, then analyzes and scrapes those e-mails for relevant data and adds pertinent LinkedIn details... Researchers liken that redirection to a so-called man-in-the-middle attack in which hackers, or more recently, intelligence agencies, intercept Internet traffic en route to its destination and do what they will with it."

White House Official Tracked Down and Fired Over Insulting Tweets 208

Hugh Pickens DOT Com writes "BBC reports that Jofi Joseph, a senior National Security Council staffer who was a key member of the White House team negotiating on Iran's nuclear weapons program, has been fired ... after a months-long probe into a barrage of tweets that included caustic criticisms of former Secretary of State Hillary Clinton and top NSC officials, especially Ben Rhodes – whom he accused of dodging questions about Benghazi. Joseph, who posted under the now defunct Twitter name @NatSecWonk, gave a lacerating commentary on anything from policy to personal appearance. 'Was Huma Abedin wearing beer goggles the night she met Anthony Weiner,' he tweeted, referring to the scandal-hit former New York mayoral candidate and his wife, a former aide of Hillary Clinton. He tweeted that Mrs Clinton 'had few policy goals and no wins' in the Middle East. He said Chelsea Clinton was 'assuming all of her parents' vices,' and targeted figures such as Republican commentator Liz Cheney and Mitt Romney's wife Ann for their looks and weight. Many in the foreign policy community reacted with shock to the revelation that Joseph was the mystery tweeter because Joseph was well known among policy wonks and his wife, Carolyn Leddy, is a well-respected professional staffer on the Republican side of the Senate Foreign Relations Committee. 'What started out as an intended parody account of DC culture developed over time into a series of inappropriate and mean-spirited comments,' said Joseph in an apology. 'I bear complete responsibility for this affair and I sincerely apologize to everyone I insulted.'"

Students Hack School-Issued iPads Within One Week 375

Hugh Pickens DOT Com writes "Los Angeles Unified School District started issuing iPads to its students this school year, as part of a $30 million deal with Apple. Now Sam Sanders reports at NPR that less than a week after getting their iPads, high school students have found a way to bypass software blocks on the devices that limit what websites the students can use. The students are getting around software that lets school district officials know where the iPads are, what the students are doing with them at all times and lets the district block certain sites, such as social media favorites like Facebook. 'They were bound to fail,' says Renee Hobbs, who's been a skeptic of the iPad program from the start. 'There is a huge history in American education of being attracted to the new, shiny, hugely promising bauble and then watching the idea fizzle because teachers weren't properly trained to use it and it just ended up in the closet.' The rollout of the iPads might have to be delayed as officials reassess access policies. Right now, the program is still in Phase 1, with fewer than 15,000 iPads distributed. 'I'm guessing this is just a sample of what will likely occur on other campuses once this hits Twitter, YouTube or other social media sites explaining to our students how to breach or compromise the security of these devices,' says Steven Zipperman. 'I want to prevent a "runaway train" scenario when we may have the ability to put a hold on the roll-out.' The incident has prompted questions about overall preparations for the $1-billion tablet initiative."

Comment To teach nonfree programs is to implant dependence (Score 1) 319

To teach use of a non-free program is to implant dependence on its owner, which contradicts the social mission of the school.

Bertrand Russell's The Impact of Science on Society (1952) should probably be given another read:

Fichte laid it down that, education should aim at destroying free will, so that, after pupils have left school, they shall be incapable, throughout the rest of their lives, of thinking or acting otherwise than as their schoolmasters would have wished [...] to produce the sort of character and the sort of beliefs that the authorities consider desirable, and any serious criticism of the powers that be will become psychologically impossible. Even if all are miserable, all will believe themselves happy, because the government will tell them that they are so.

Fighting Zombies? Chevrolet Reveals New "Black Ops" Concept Truck 220

cartechboy writes "Whether its the Mayan calendar, a rough economy, or a fear of zombies, there are people who are currently preparing for the end of the world, coming, like, soon. And they can attract some fringe elements. So maybe those elements are worth a little truck marketing. Yesterday at the Texas State Fair, Chevrolet unveiled a "Black Ops" concept truck that it says will "explore the extremes of preparedness." The truck comes with a vault storage unit, solar power pack, gas masks, gloves, a military first aid kit, a folding shovel, a generator and some rope. Twinkies apparently not included."

Scientists Create New "Lightsaber-Like" Form of Matter 175

First time accepted submitter loftarasa writes "A group of scientists led by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic have developed a form of matter by binding massless photons together in a special kind of medium to create 'photonic molecules', effectively bringing us a bit closer to a world with lightsabers. 'The discovery, Lukin said, runs contrary to decades of accepted wisdom about the nature of light. Photons have long been described as massless particles which don't interact with each other – shine two laser beams at each other, he said, and they simply pass through one another. "Photonic molecules," however, behave less like traditional lasers and more like something you might find in science fiction – the light saber.' The work is described in Nature (paywalled)."

Space Food From Space Farms 168

Modern Farmer magazine has an article about NASA's efforts into growing food in space, a slow, difficult process that's nonetheless necessary if humanity is to have any significant presence away from Earth's surface. Quoting: "This December, NASA plans to launch a set of Kevlar pillow-packs, filled with a material akin to kitty litter, functioning as planters for six romaine lettuce plants. The burgundy-hued lettuce (NASA favors the 'Outredgeous' strain) will be grown under bright-pink LED lights, ready to harvest after just 28 days. NASA has a long history of testing plant growth in space, but the goals have been largely academic. Experiments have included figuring out the effects of zero-gravity on plant growth, testing quick-grow sprouts on shuttle missions and assessing the viability of different kinds of artificial light. But [the Vegetable Production System] is NASA's first attempt to grow produce that could actually sustain space travelers. Naturally, the dream is to create a regenerative growth system, so food could be continually grown on the space station — or, potentially, on moon colonies or Mars. ... Plant size is a vital calculation in determining what to grow on the space station, where every square foot is carefully allotted. Harvest time is also of extreme importance; the program wants to maximize growth cycles within each crew’s (on average) six-month stay."

White House: Use Metric If You Want, We Don't Care 1145

Earlier this year we discussed a petition on the White House's 'We The People' site asking the administration to adopt the metric system as the standard system of measurement in the U.S. Today, the administration issued a disappointing response. Simply put: they're not going to do anything about it. They frame their response as a matter of preserving a citizen's choice to adopt whatever measurement system he wants. Quoting Patrick D. Gallagher of the National Institute of Standards and Technology: "... contrary to what many people may think, the U.S. uses the metric system now to define all basic units used in commerce and trade. At the same time, if the metric system and U.S. customary system are languages of measurement, then the United States is truly a bilingual nation. ... Ultimately, the use of metric in this country is a choice and we would encourage Americans to continue to make the best choice for themselves and for the purpose at hand and to continue to learn how to move seamlessly between both systems. In our voluntary system, it is the consumers who have the power to make this choice. So if you like, "speak" metric at home by setting your digital scales to kilograms and your thermometers to Celsius. Cook in metric with liters and grams and set your GPS to kilometers. ... So choose to live your life in metric if you want, and thank you for signing on."

Psychiatrists Cast Doubt On Biomedical Model of Mental Illness 329

jones_supa writes "British Psychological Society's division of clinical psychology (DCP) will on Monday issue a statement declaring that, given the lack of evidence, it is time for a 'paradigm shift' in how the issues of mental health are understood. According to their claim, there is no scientific evidence that psychiatric diagnoses such as schizophrenia and bipolar disorder are valid or useful. The statement effectively casts doubt on psychiatry's predominantly biomedical model of mental distress – the idea that people are suffering from illnesses that are treatable by doctors using drugs. The DCP said its decision to speak out 'reflects fundamental concerns about the development, personal impact and core assumptions of the (diagnosis) systems', used by psychiatry. The provocative statement by the DCP has been timed to come out shortly before the release of DSM-5, the fifth edition of the American Psychiatry Association's Diagnostic and Statistical Manual of Mental Disorders. The manual has been attacked for expanding the range of mental health issues that are classified as disorders."
