Why Small-Scale Biomass Energy Projects Aren't a Solution To Climate Change 178

Posted by samzenpus from the try-something-else dept.
Lasrick writes "Roberto Bissio has an excellent piece in a roundtable on biomass energy, pointing out that small scale biomass energy projects designed for people in poor countries aren't really a solution to climate change. After pointing out that patent protections could impede wide-spread adoption, Bissio adds that the people in these countries aren't really contributing to climate change in the first place: 'Why? Because poor people, whose carbon emissions these technologies would reduce, produce very little carbon in the first place. As I mentioned in Round One, the planet's poorest 1 billion people are responsible for only 3 percent of global carbon emissions. The 1.26 billion people whose countries belong to the Organization for Economic Co-operation and Development account for 42 percent of emissions. The rich, if they reduced their emissions by just 8 percent, could achieve more climate mitigation than the poor could achieve by reducing their emissions to zero. The rich could manage this 8 percent reduction by altering their lifestyles in barely noticeable ways. For the poor, a reduction of 100 percent would imply permanent misery.'"

Gravity: Can Film Ever Get the Science Right? 438

Posted by samzenpus from the suspension-of-disbelief dept.
dryriver writes in with a story lamenting the lack of accurate science in movies. "The relationship between science and science fiction has always been tempestuous. Gravity focuses on two astronauts stranded in space after the destruction of their space shuttle. Since Gravity's US release (it comes to the UK in November) many critics have praised the film for its scientific accuracy. But noted astrophysicist Dr Neil deGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History in New York, had several issues with the accuracy of Gravity's portrayal of space. Through a series of posts on Twitter, Tyson — who later emphasized that he 'enjoyed the film very much' — highlighted various errors. He noted the Hubble space telescope (orbiting at 350 miles above sea level), the International Space Station (at 250 miles), and a Chinese space station could never be in line of sight of one another. On top of that, most satellites orbit west to east, yet in the film the satellite debris was seen drifting east to west. Tyson also noted how Sandra Bullock's hair did not float freely as it would in zero-gravity. This is arguably not so much an error in physics, but a reflection of the limitations of cinematic technology to accurately portray actors in zero-gravity. That is, of course, without sending them into space for the duration of the film. The Michael Bay film Armageddon is known for its woeful number of inaccuracies, from the space shuttles separating their rocket boosters and fuel tanks in close proximity to each other (risking a collision) and to objects falling on to the asteroid under a gravitational pull seemingly as strong as the Earth's. More than one interested observer tried to work out how big the bomb would have to be to blow up an asteroid in the way demanded in the movie. Answer: Very big indeed. Nasa is reported to have even used Armageddon as part of a test within their training program, asking candidates to identify all the scientific impossibilities within the film."

Lessons From the Healthcare.gov Fiasco 501

Posted by samzenpus from the better-luck-next-time dept.
Nerval's Lobster writes "In theory, the federal government's Health Insurance Marketplace was supposed to make things easy for anyone in the market for health insurance. But fourteen days after the Website made its debut, the online initiative—an integral part of the Obama administration's Affordable Care Act—has metastasized into a disaster. Despite costing $400 million (so far) and employing an army of experienced IT contractors (such as Booz Allen Hamilton and CGI Group), the Website is prone to glitches and frequent crashes, frustrating many of those seeking to sign up for a health-insurance policy. Unless you're the head of a major federal agency or a huge company launching an online initiative targeted at millions of users, it's unlikely you'll be the one responsible for a project (and problems) on the scale of the Health Insurance Marketplace. Nonetheless, the debacle offers some handy lessons in project management for Websites and portals of any size: know your IT specifications (federal contractors reportedly didn't receive theirs until a few months ago), choose management capable of recognizing the problems that arise (management of Healthcare.gov was entrusted to the Medicare and Medicaid agency, which didn't have the technical chops), roll out small if possible, and test, test, test. The Health Insurance Marketplace fiasco speaks to an unfortunate truth about Web development: even when an entity (whether public or private, corporation or federal government) has keen minds and millions of dollars at its disposal, forgetting or mishandling the basics of successful Web construction can lead to embarrassing problems."

Michael Ross writes "An online store is one of the most common use cases for a website nowadays. For those web developers and business owners who choose the current version of Drupal as a basis for such an e-commerce project, the canonical solution is Drupal Commerce. There are numerous online resources for learning Commerce, and yet for the longest time no printed book. Now we have Getting Started with Drupal Commerce, written by Richard Jones."

Ford, University of Michigan Open Next-Generation EV Battery Research Lab 67

Posted by samzenpus from the giving-it-a-charge dept.
cartechboy writes "Its no secret that one constraint on electric vehicle adoption is battery production capacity and cost. Right now battery costs add thousands of dollars in price tags on electric vehicles, so the race is on to gain capacity make cheaper batteries. Today, Ford and the University of Michigan are announcing an $8 million EV experimental battery research lab to try and accelerate this type of early testing. The lab, which will be on campus in Ann Arbor, Michigan, will allow automakers, battery makers and individual researchers to test battery cells earlier in the process than ever. The lab says it will have strict controls to protect each entity's individual intellectual property as the research in theory happens all in one place."

What's Lost When a Meeting Goes Virtual 96

Posted by samzenpus from the from-the-comfort-of-your-own-house dept.
nbauman writes "This summer, NASA's Lunar Science Forum became the largest scientific gathering to embrace the new world of cyber meetings. The experience drew mixed reviews, according to a report in Science magazine. Mihály Horányi, who has been a regular, sat down at his computer at 1:45 p.m. on the first day of the conference and began talking into a webcam perched above the screen. 'Last year it was a performance. This year it meant staring at myself, being annoyed that I kept leaning in and out of the picture, and thinking, "Boy, am I getting old."' He and other participants say the virtual conference was a pale imitation of the real thing. At previous forums, 'You see your friends, you ask about their kids, and then the discussion flows into the science.' He participated much less this year, 2 hours a day. In addition to the physical challenge of sitting at one's computer for hours on end, participants say that their day jobs competed for their attention. 150 to 200 people "attended" at any one time. Even without distractions, the quality of the interaction was much lower than in person. 'I received a handful of short comments [from my talk] and had maybe one e-mail exchange,' Horányi recalls. One scientist who didn't present this year—and who listened to only one talk after the fact—said that he much prefers an in-person meeting because 'you get a much better sense of how the audience is reacting to what you're saying, especially any negative feedback.'"

Grocery Store "Smart Shelves" Will Identify Customers, Show Targeted Ads 274

Posted by samzenpus from the watching-you dept.
cagraham writes "Snack company Mondelez International (maker of Oreos, Trident, Cadbury eggs) will introduce so-called 'smart shelves' into store checkout aisles beginning 2015. The shelves will use Microsoft's Kinect software, in addition to other tech, to identify shoppers age and sex, and will then use that info to deliver demographically tailored advertisements. The shelves will be able to track engagement, monitor how long customer's watch each ad, and offer discounts if a customer is considering a purchase (weight sensors will tell the machine if you pick up a product). Mondelez says the software will only use and collect aggregate data, and will not record any video or photos."

Brazil Announces Secure Email To Counter US Spying 165

Posted by samzenpus from the keep-your-eyes-on-your-own-paper dept.
Hugh Pickens DOT Com writes "Phys Org reports that Brazilian President Dilma Rousseff has announced her government is creating a secure email system to try and shield official communications from spying by the United States and other countries. 'We need more security on our messages to prevent possible espionage,' Rousseff said on Twitter, ordering the Federal Data Processing Service, or SERPRO, to implement a safe email system throughout the federal government. The move came after Rousseff publicly condemned spying against Brazilian government agencies attributed to the United States and Canada. 'This is the first step toward extending the privacy and inviolability of official posts,' Rousseff said. After bringing her complaints against U.S. intelligence agencies to the United Nations General Assembly last month and canceling a state visit to Washington, Rousseff announced that the country will host an international conference on Internet governance in April."

Books With "Questionable Content" Being Deleted From ebookstores In Sweeping Ban 548

Posted by samzenpus from the cleaning-things-up dept.
Nate the greatest writes "The Kernel started an uproar last week when they 'discovered' that the Kindle Store and other ebookstores sell adult content in the erotica category. None of the content is actually illegal, but it is icky enough that the major ebookstores decided to respond by removing anything even vaguely questionable. Unfortunately, they went too far, resulting in an act of censorship the likes of which we haven't seen since Paypal went after the indie ebook distributor Smashwords. The Daily Mail reports that WH Smith went so far as to shut down their website with the promise that it won't reopen until all self-published titles have been removed, and according to BBC News, B&N is also deleting content. Numerous authors have reported on KBoards that Amazon and B&N have removed far more than just the titles that feature questionable content like pseudo-incest; they appear to be running keyword searches and removing any title that mentions innocuous words like babysitter, sister, or teenager. And they're not the only ones; there's a new report that Kobo has jumped on the ban wagon as well."

Billion Year Storage Media 204

Posted by samzenpus from the built-to-last dept.
Thorfinn.au writes "Even though the data density of digital information storage has increased tremendously over the last few decades, the data longevity is limited to only a few decades. If we want to preserve anything about the human race which can outlast the human race itself, we require a data storage medium designed to last for 1 million to 1 billion years. In this paper a medium is investigated consisting of tungsten encapsulated by silicon nitride which, according to elevated temperature tests, will last for well over the suggested time."

First Evidence Found of a Comet Strike On Earth 68

Posted by samzenpus from the big-boom dept.
mdsolar writes in with a story about evidence of a comet explosion over Egypt 28 million years ago. "Saharan glass and a brooch belonging to King Tut provide the first evidence of a comet directly impacting Earth, a new study claims. The finding may help unlock some of the mysteries surrounding the birth of our solar system. About 28 million years ago a comet exploded over Egypt, creating a 3600F (2000C) blast wave that spread out over the desert below. The fiery shockwave melted the sand, forming copious amounts of yellow silica glass scattered over 2,300 square miles (6,000 square kilometers) of the Sahara. Polished into the shape of a scarab beetle, a large piece of this glass found its way into a brooch owned by the famed Egyptian boy king Tutankhamen. 'Because there is no sign of an impact crater, it has been a mystery as to what kind of celestial event actually could have caused this debris field, but a small, black stone found lying in the middle of the glass area caught our attention,' said study co-author David Block, an astronomer at Wits University in Johannesburg, South Africa."

Netflix Pursues Cable-TV Deals 93

Posted by samzenpus from the on-demand dept.
An anonymous reader writes "Netflix is making a push to make its online video service available as an app on set-top boxes. 'A deal would mark the online video service's first such tie-up with a U.S. cable provider and would come after a similar agreement it recently announced with U.K. cable operator Virgin Media Inc. The talks are in early stages and no deal is imminent, the people cautioned. Netflix and U.S. pay-TV companies are rivals in some key respects. Netflix's subscription video offering is an attractive alternative for some consumers who are frustrated with costly cable bills. And both sides want to be the go-to destination for consumers to find on-demand TV programming.'"

D-Link Router Backdoor Vulnerability Allows Full Access To Settings 228

Posted by samzenpus from the protect-ya-neck dept.
StealthHunter writes "It turned out that just by setting a browsers user-agent to 'xmlset_roodkcableoj28840ybtide' anyone can remotely bypass all authentication on D-Link routers. It seems that thttpd was modified by Alphanetworks who inserted the backdoor. Unfortunately, vulnerable routers can be easily identified by services like shodanHQ. At least these models may have vulnerable firmware: DIR-100, DI-524, DI-524UP, DI-604S, DI-604UP, DI-604+, TM-G5240."
