Nom du Keyboard writes "Recently word leaked out about Amazon removing titles containing fictional incest. Surprisingly that ban didn't extend to the 10 titles of Science Fiction Grand Master Robert A. Heinlein that incorporate various themes of incest and pedophilia. Now, it seems that the censorship is expanding to m/m gay fiction if it contains the magic word 'rape' in the title. Just how far is this going to be allowed to proceed in relative silence, and who is pushing these sudden decisions on Amazon's part?"

An anonymous reader writes "The Seoul Metropolitan Government just rolled out the world's first commercial all-electric bus service. The buses were designed to be as efficient as possible — each bus can run up to about 52 miles on a single charge and they have a maximum speed of about 62 miles per hour. The vehicles' lithium-ion battery packs can be fully charged in less than 30 minutes and they also feature regenerative braking systems that reuse energy from brakes when running downhill."

aztec1430 writes "Airplane!, The Empire Strikes Back, The Exorcist, and All the President's Men, were among the 25 films named by the Library of Congress to the National Film Registry on Tuesday for their cultural, historical or aesthetic significance. Now, which version was added? And will each new Lucas-a-fied version need to be resubmitted every year? ;)"

An anonymous reader writes "Elliptic Labs will reveal their Touchless Gesture User Interface technology at CES 2011. Elliptic Labs sprung forth from the signal processing environment at the University of Oslo and what they've come up with is an [iPad] dock which creates a 'touchless zone' that extends out about 1 foot in front and to the sides of the iPad screen. Users can then initiate a number of gestures, much like on Microsoft Kinect, to manipulate onscreen content."

chromatic writes "To answer the perennial question 'How can we teach kids how to program?', we created a web-based programming environment. As we began to write lessons and examples, we surprised ourselves. Modern languages may be powerful and useful for writing real programs, but BASIC and Logo are great languages for demonstrating the joy of programming."

wooferhound passes along this quote from the Orlando Sentinel: "Thanks to congressional inaction, NASA must continue to fund its defunct Ares I rocket program until March — a requirement that will cost the agency nearly $500 million at a time when NASA is struggling with the expensive task of replacing the space shuttle. About one-third of that money — $165 million — will go to Alliant Techsystems, or ATK, which has a $2 billion contract to build the solid-rocket first stage for the Ares I, the rocket that was supposed to fill the shuttle's role of transporting astronauts to the International Space Station. ... The odd scenario, in which NASA is throwing money at a canceled rocket program but can't fund a modernization program, is because of several twists in the legislative process that started a year ago and came to a head this month. At the root of the problem is a 70-word sentence inserted into the 2010 budget — by lawmakers seeking to protect Ares I jobs in their home states — that bars NASA from shutting down the program until Congress passed a new budget a year later. That should have happened before the Oct. 1 start of the federal fiscal year. But Congress never passed a 2011 budget and instead voted this month to extend the 2010 budget until March — so NASA still must abide by the 2010 language."

tcd004 writes "If you added the YouTube Facebook app prior to 2009, you've given YouTube free access to nearly all the data in your profile (as well as many of your friends). But if you install the same app today, it gets very limited access. Older versions of Facebook apps, it turns out, still have 'grandfathered' access to data that the social networking service has restricted for new apps. If you're protective of your privacy, it might be a good idea to delete and reinstall any older apps in your profile."

burnin1965 writes in to let us know that the looming crisis in rare-earth materials (which we have discussed recently) has prompted Molycorp, the erstwhile operator of a California mine closed in 2002, to announce plans to reopen it. "With increasing prices on rare earth ore, tariffs raised by the Chinese government, and the threat of embargoes that would damage United States high-tech manufacturing Molycorp now has the needed incentive to reopen the California Mountain Pass mine. They will spend the capital needed to implement badly needed updates to environmental controls that will mitigate the radioactive waste water releases that plagued the mine in the past. Chinese imports in the 90s nearly halved ore prices and the California mine experienced multiple failures in environmental controls that resulted in the release of huge volumes of radioactive waste water. Updating the mine to address the environmental issues was not financially viable due to the cheap Chinese imports so it was closed in 2002." Within two years the mine could be producing 20% of the amount of rare earths we import from China.

University of Idaho scientists have figured out a more effective way to track woodpecker populations than following the incessant laughter. They're using a laser onboard NASA's Icesat spacecraft to determine where the birds might be living. From the article: "NASA's Icesat satellite was initially intended for measuring glacial surfaces at the Earth's poles but has proven to be quite effective in measuring vegetation also. The satellite's laser bounces off of forest canopies, tree trunks and the ground making important characteristics about the forest easily measurable. For example, forest density is determined by the relative amount of light returned versus that which is returned from the ground. Once ideal woodpecker locations are identified 'we actually conduct ground-based woodpecker surveys in these locations as well to verify it,' says team-member Patrick Adam."

RogerRoast sends along a backgrounder from Scientific American on the best current theory as to why the north magnetic pole drifts. "The NMP, also known as the dip pole, is the point on Earth where the planet's magnetic field points straight down into the ground. Scottish explorer James Clark Ross first located the NMP in 1831 on the Boothia Peninsula in what is now northern Canada... [T]he NMP drifts from year to year as geophysical processes within Earth change. For more than 150 years after Ross's measurement its movement was gradual, generally less than 15 kilometers per year. But then, in the 1990s, it picked up speed, ... bolting north–northwest into the Arctic Ocean at more than 55 kilometers per year. If it keeps going it could pass the geographic north pole in a decade or so and carry on toward Siberia."

Relic of the Future writes "Seen on the blog 'Algorithmic Game Theory,' a report to congress and the president about past and future advances in information technology notes that, while improvements in hardware accounted for an approximate 1,000 fold increase in calculation speed over a 15-year time-span, improvements in algorithms accounted for an over 43,000 fold increase."

Modern Perl writes "Larry Wall, the creator of Perl, reflects on Perl's history of hacking its culture, from subverting the reductionist culture of Unix to reinventing the ideas of programming language and culture in Perl 6 and the verbal aikido used to encourage honest detractors to become valuable contributors. Perl turned 23 years old last week, and Perl 6 is available."
