eldavojohn writes "A Japanese/Algerian effort called The Sahara Solar Breeder Project employs a simple concept revolving around the pure silica in the sand of the Sahara Desert. The silica can be used to build vast solar arrays which will then provide the power and means to build more solar arrays in a classic breeder model. They would then use DC powerlines utilizing high temperature superconductors. The lead of the project points out that silica is the second most abundant resource in the Earth's crust. The project's lofty goals to harness the Sahara's energy has a few requirements — including 100 million yen annually — but also the worldwide cooperation of many nations and the training of the scientists and engineers to create and man these desert plants. The once deadly wasteland of the Sahara now looks like a land rich in an important resource: sunlight."

storagedude writes "There seems to be no end to the ways your personal data and online behavior can be used against you. According to the Wall Street Journal, insurance companies are considering using online behavioral and social networking data to try to weed out insurance risks. What you read, what you buy, how much TV you watch, your credit, your fan pages... it could all be used to predict your longevity and insurance risk. The practice, which appears to be in the early stages, could raise concerns with the FTC and insurance regulators, but insurance and data mining companies say they just plan to use it to speed up the applications of people who appear to be good risks; others would have to go through more rigorous traditional screening."

climenole tips a great article by Sir Tim Berners-Lee in Scientific American. Quoting: "The Web evolved into a powerful, ubiquitous tool because it was built on egalitarian principles and because thousands of individuals, universities and companies have worked, both independently and together as part of the World Wide Web Consortium, to expand its capabilities based on those principles. The Web as we know it, however, is being threatened in different ways. Some of its most successful inhabitants have begun to chip away at its principles. Large social-networking sites are walling off information posted by their users from the rest of the Web. Wireless Internet providers are being tempted to slow traffic to sites with which they have not made deals. Governments — totalitarian and democratic alike — are monitoring people's online habits, endangering important human rights. If we, the Web's users, allow these and other trends to proceed unchecked, the Web could be broken into fragmented islands. We could lose the freedom to connect with whichever Web sites we want."

michaelmarshall writes "For the first time, life has been found in the gabbroic layer of the crust. The new biosphere is all bacteria, as you might expect, but they are different from the bacteria in the layers above; they mostly feed on hydrocarbons that are produced by abiotic reactions deep in the crust. It could mean that similar microbes are living even deeper, perhaps even in the mantle."

Hugh Pickens writes "Researchers at MIT have developed a laser camera that can 'see' around corners and take pictures of a scene not in its direct line of sight. The camera system fires extremely short bursts of light that can reflect off one object, such as the open door of a room, and then off a second object inside the room before reflecting back to the first object and being captured by the camera, after which algorithms can use the information to reconstruct the hidden scene exploiting the fact that it is possible to capture light at extremely short time scales, about one quadrillionth of a second. By continuously gathering light and computing the time and distance that each pixel has traveled, the camera creates a '3D time-image' of the scene it can't directly see. 'It's like having X-ray vision without the X-rays,' says Professor Ramesh Raskar. 'We're going around the problem rather than going through it.'"

brothke writes "Security Engineering: A Guide to Building Dependable Distributed Systems by Ross Anderson is arguably the best information security book ever written. Anderson's premise is that security technology needs to take a structured engineering approach to systems design, with detailed requirements and specification from start-up to development and implementation; just as those designing buildings and bridges do. Without a deeply embedded structured approach to security systems design, Anderson argued that we find ourselves in the situation we are in today, with applications and operating systems full of bugs, vulnerabilities and other serious security flaws. As good as Security Engineering is, it was not written to be a detailed information security design guide. That vacuum has been filled by an incredibly important and valuable new bookSecurity Strategy: From Requirements to Reality." Read on for the rest of Ben's review.

CWmike writes "Columbia law professor Tim Wu, who coined the term 'net neutrality,' now says that Apple is the company that most endangers the freedom of the Internet. Wu recently published the book The Master Switch: The Rise and Fall of Information Empires, in which he details what he calls 'information empires' such as AT&T, NBC, Facebook, and Google. He told The New York Times, 'It's largely a story of the American affection for information monopolists and the consequences of that fondness.' When asked whether the Internet could similarly be controlled by large companies, he told the Times: 'I know the Internet was designed to resist integration, designed to resist centralized control, and that design defeated firms like AOL and Time Warner. But firms today, like Apple, make it unclear if the Internet is something lasting or just another cycle.' Asked which companies he feared most, Wu replied: 'Right now, I'd have to say Apple.'" Wu has been in the news a bit lately.

An anonymous reader writes in about a protest called for the busiest airline travel day of the year. "An activist opposed to the new invasive body scanners in use at airports around the country just designated Wednesday, Nov. 24 as a National Opt-Out Day. He's encouraging airline passengers to decline the TSA's technological strip searches en masse on that day as a protest against the scanners, as well as the new 'enhanced pat-downs' inflicted on refuseniks. 'The goal of National Opt-Out Day is to send a message to our lawmakers that we demand change,' reads the call to action at OptOutDay.com, set up by Brian Sodegren. 'No naked body scanners, no government-approved groping. We have a right to privacy, and buying a plane ticket should not mean that we're guilty until proven innocent.' The US Airline Pilots Association and other pilot groups have urged their members to avoid the scanners and have also condemned the new pat-down policy as humiliating to pilots. They've advised pilots who don't feel comfortable undergoing pat-downs in front of passengers to request they be conducted in a private room. Any pilots who don't feel comfortable after undergoing a pat-down have been encouraged to 'call in sick and remove themselves from the trip.'"

ihaque writes "A Stanford researcher, Philip Guo, has developed a tool called CDE to automatically package up a Linux program and all its dependencies (including system-level libraries, fonts, etc!) so that it can be run out of the box on another Linux machine without a lot of complicated work setting up libraries and program versions or dealing with dependency version hell. He's got binaries, source code, and a screencast up. Looks to be really useful for large cluster/cloud deployments as well as program sharing. Says Guo, 'CDE is a tool that automatically packages up the Code, Data, and Environment involved in running any Linux command so that it can execute identically on another computer without any installation or configuration. The only requirement is that the other computer have the same hardware architecture (e.g., x86) and major kernel version (e.g., 2.6.X) as yours. CDE allows you to easily run programs without the dependency hell that inevitably occurs when attempting to install software or libraries. You can use CDE to allow your colleagues to reproduce and build upon your computational experiments, to quickly deploy prototype software to a compute cluster, and to submit executable bug reports.'"

Last year we discussed news that researchers from Oxford University discovered playing Tetris after watching a disturbing film reduced the amount of intrusive flashbacks experienced by test subjects. The researchers then wondered if that was true for other games, so they began a new study, the results of which were just published in the journal PLoS ONE. Reader SpuriousLogic points out that while they repeated their earlier finding about Tetris, they also found that subjects who played trivia game Pub Quiz instead reported more flashbacks. "Research tells us that there is a period of up to six hours after the trauma in which it is possible to interfere with the way that these traumatic memories are formed in the mind. During this time-frame, certain tasks can compete with the same brain channels that are needed to form the memory. This is because there are limits to our abilities in each channel: for example, it is difficult to hold a conversation while doing math problems. The Oxford team reasoned that recognizing the shapes and moving the colored building blocks around in Tetris competes with the images of trauma in the perceptual information channel. Consequently, the images of trauma (the flashbacks) are reduced. The team believe that this is not a simple case of distracting the mind with a computer game, as answering general knowledge questions in the Pub Quiz game increased flashbacks. The researchers believe that this verbal based game competes with remembering the contextual meaning of the trauma, so the visual memories in the perceptual channel are reinforced and the flashbacks are increased."

netbuzz writes "David Kernell, whose prying into Sarah Palin's personal e-mail account caused an uproar two months before the 2008 presidential election, was today sentenced to a year and a day by a judge in Knoxville, Tenn. Kernell was convicted of misdemeanor computer fraud and felony obstruction of justice back in April. His attorney had argued for probation on the grounds that what Kernell did amounted to a prank that spun out of control."

Muad writes "Michael Kerrisk has been the maintainer of the Linux Man Pages collection (man 7) for more than five years now, and it is safe to say that he has contributed to the Linux documentation available in the online manual more than any other author before. For this reason he has been the recipient a few years back of a Linux Foundation fellowship meant to allow him to devote his full time to the furthering this endeavor. His book is entirely focused on the system interface and environment Linux (and, to some extent, any *NIX system) provides to a programmer. My most obvious choice for a comparison of the same caliber is Michael K. Johnson and Eric W. Troan's venerable Linux Application Development, the second edition of which was released in 2004 and is somewhat in need of a refresh, lamentably because it is an awesome book that belongs on any programmer's shelf. While Johnson and Troan have introduced a whole lot of programmers to the pleasure of coding to Linux's APIs, their approach is that of a nicely flowing tutorial, not necessarily complete, but unusually captivating and very suitable to academic use. Michael's book is a different kind of beast: while the older tome selects exquisite material, it is nowhere as complete as his — everything relating to the subject that I could reasonably think of is in the book, in a very thorough and maniacally complete yet enjoyably readable way — I did find one humorous exception, more on that later. Keep reading for the rest of Federico's review.

dvdme writes "It seems the placebo effect isn't just valid on drugs. It's also a fact on elevators, offices and traffic lights. An article by Greg Ross says: 'In most elevators installed since the early 1990s, the 'close door' button has no effect. Otis Elevator engineers confirmed the fact to the Wall Street Journal in 2003. Similarly, many office thermostats are dummies, designed to give workers the illusion of control. "You just get tired of dealing with them and you screw in a cheap thermostat," said Illinois HVAC specialist Richard Dawson. "Guess what? They quit calling you." In 2004 the New York Times reported that more than 2,500 of the 3,250 "walk" buttons in New York intersections do nothing. "The city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals, even as an unwitting public continued to push on."'"

nicholasjay writes "Netflix is swallowing America's bandwidth and it probably won't be long before it comes for the rest of the world. That's one of the headlines from Sandvine's Fall 2010 Global Internet Phenomena Report, an exhaustive look at what people around the world are doing with their Internet lines. According to Sandvine, Netflix accounts for 20 percent of downstream Internet traffic during peak home Internet usage hours in North America. That's an amazing share — it beats that of YouTube, iTunes, Hulu, and, perhaps most tellingly, the peer-to-peer file-sharing protocol BitTorrent."

arkenian writes "Difficult-to-read fonts make for better learning, according to scientists. The finding is about to be published in the international journal Cognition. Researchers at Princeton University employed volunteers to learn made-up information about different types of aliens — and found that those reading harder fonts recalled more when tested 15 minutes later. The article goes on to note a second test in a real school environment: 'Keen to see if their findings actually worked in practice, the Princeton University team then tested their results on 222 students aged between 15 and 18 at a secondary school in Chesterfield, Ohio.'... 'Students given the harder-to-read materials scored higher in their classroom assessments than those in the control group. This was the case across a range of subjects — from English, to Physics to History.'"
