First time accepted submitter Noctis-Kaban writes "Scientists in China have built and tested a radical new space drive. Although the thrust it produces may not be enough to lift your mobile phone, it looks like it could radically change the satellite industry. Satellites are just the start: with superconducting components, this technology could generate the thrust to drive everything from deep space probes to flying cars. And it all started with a British engineer whose invention was ignored and ridiculed in his home country."

Zothecula writes "Use digital technology long enough and you start to become dependent upon it for such mundane tasks as spell checking. That means when you pick up a garden variety ballpoint pen you're back in dictionary and 'I before E except after C' territory. The creators of the Lernstiftdigital pen hope to bring handwriting into the 21st century by having the pen vibrate to indicate when the writer makes spelling and grammatical errors or exhibits poor penmanship."
sciencehabit writes "The ancestor of all placental mammals—the diverse lineage that includes almost all species of mammals living today, including humans—was a tiny, furry-tailed creature that evolved shortly after the dinosaurs disappeared, a new study suggests. The hypothetical creature, not found in the fossil record but inferred from it, probably was a tree-climbing, insect-eating mammal that weighed between 6 and 245 grams—somewhere between a small shrew and a mid-sized rat. It was furry, had a long tail, gave birth to a single young, and had a complex brain with a large lobe for interpreting smells and a corpus callosum, the bundle of nerve fibers that connects the left and right hemispheres of the brain. The period following the dinosaur die-offs could be considered a 'big bang' of mammalian diversification, with species representing as many as 10 major groups of placentals appearing within a 200,000-year interval."
astroengine writes "The Earth has one permanent moon — you know, 'The Moon' — but at any given time there are thought to be two temporary interlopers that were once asteroids, but get captured by our planet's gravity to become mini-moons for a few months or even years. They eventually get flung back out into interplanetary space. This ultimate 'catch and release' provides an interesting opportunity for any future asteroid mission. So now astronomers want to find them, possibly using the newly-minted Hubble-class spy telescopes donated to NASA by the National Reconnaissance Office."

'Called DropTag, the gadget combines a battery, a low-energy Bluetooth transmitter, an accelerometer and a memory chip. Stuck on a parcel as it leaves an e-commerce warehouse, it logs any g-forces above a set risky shock level that it experiences. The idea is that when the courier puts it in your hands, you turn on Bluetooth on a smartphone running a DropTag app and scan it before you sign for it.'"
New submitter markfeffer, Senior Editor at Dice, writes "Red Hat's hired about 600 people in its last three fiscal quarters, and it's going to keep hiring – about 900 to 1,000 more this year. The company's primarily looking for software and technical support engineers, along with salespeople who can help strengthen its cloud-technology capabilities. They want people with strong technical skills, of course, but the company puts a premium on those who've taken the time to research its business and send in a resume that's custom-tailored to the job opening."

The president of the firm who audits many of the country's broadband meters says that he can't certify the measurements produced by five out of seven of his clients' meters because they don't count your bits correctly
First time accepted submitter Sagan's Pie writes "I'm starting to look for a laptop for college, and the only thing I seem to find are laptops or tablets that have Windows 8. I have used Windows 7 for a long time now, and would not have a problem giving it up, but not for Windows 8. After visiting many major online retail sites, I've found that finding either a Windows 7 laptop, or even a laptop without an operating system is nearly impossible. So where should I go if looking for laptops sans os, or at the very least sans Windows 8?"
astroengine writes "By focusing the Green Bank radio telescope on stars hosting (candidate) exoplanets identified by NASA's Kepler space telescope, it is hoped that one of those star systems may also play host to a sufficiently evolved alien race capable of transmitting radio signals into space. But in a study headed by ex-SETI chief Jill Tarter, the conclusion of this first attempt is blunt: 'No signals of extraterrestrial origin were found.' But this is the just first of the 'directed' SETI searches that has put some very important limits on the probability of finding sufficiently advanced alien civilizations in our galaxy."
clustro writes "Deloitte predicts that 8-character passwords will become insecure in 2013. Humans have trouble remembering passwords with more than seven characters, and it is difficult to enter long, complex passwords into mobile devices. Users have not adapted to increased computing power available to crackers, and continue to use bad practices such as using common and short passwords, and re-using passwords across multiple websites. A recent study showed that using the 10000 most common passwords would have cracked >98% of 6 million user accounts. All of these problems have the potential for a huge security hazard. Password vaults are likely to become more widely used out of necessity. Multifactor authentication strategies, such as phone texts, iris scans, and dongles are also likely to become more widespread, especially by banks."
First time accepted submitter LiteWait writes "My son is heading off to college next year and although he is bright kid with a great background in math and science, he has indicated that he'd like learn some introductory programming skills this summer. The courses at the local universities are pretty sparse and most of the CS101-type courses I've seen offered are too general to meet his needs. Even though he is a self-starter I think he would benefit from actual courses/code camps/etc rather than just slogging through online samples and tutorials. I'd like some advice on possible options for code camps, online courses, or developer training."
Michael Ross writes "Web designers, graphics artists, and others who create and edit digital images, have a number of commercial image-manipulation packages from which they can choose — such as Adobe Photoshop and Adobe Fireworks (originally developed by Macromedia). Yet there are also many alternatives in the open-source world, the most well-known being GNU Image Manipulation Program. GIMP is available for all major operating systems, and supports all commonly-used image formats. This powerful application is loaded with features, including plug-ins and scripting. Yet detractors criticize it as being complicated (as if Photoshop is intuitively obvious). Admittedly, anyone hoping to learn it could benefit from a comprehensive guide, such as The Book of GIMP." Keep reading for the rest of Michael's review.
Nerval's Lobster writes "Software developer Jeff Cogswell is back with an extensive under-the-hood breakdown of Facebook's Graph Search, trying to see if peoples' privacy concerns about the social network's search engine are entirely justified. His conclusion? 'Some of the news articles I've read talk about how Graph Search will start small and slowly grow as it accumulates more information. This is wrong—Graph Search has been accumulating information since the day Facebook opened and the first connections were made in the internal graph structure,' he writes. 'People were nervous about Google storing their history, but it pales in comparison to the information Facebook already has on you, me, and roughly a billion other people.' There's much more at the link, including a handy breakdown of graph theory."
CES this year was with Ubuntu Community Manager Jono Bacon, who was showing off the Ubuntu Phone that is supposed to be released later this year. According to the Ubuntu website, it "delivers a magical phone that is faster to run, faster to use and fits perfectly into the Ubuntu family." Big words, but if Ubuntu parent Canonical can live up to them, the mobile phone market may soon have an interesting new operating system competitor to shake things up.
Frequent contributor Bennett Haselton is still thinking about prediction markets, and giving away money. He writes: "In an article last December I described a problem with prediction markets, where even markets with cap on betting limits could be manipulated by a single trader willing to spend a lot of money to distort the marketplace odds. So I offered a $100 cash prize to be split between readers who collectively came up with the best solution to the problem. Here's an idea that I think would work." Read on for the rest.
tsamsoniw writes "While research companies including IDC and Gartner deemed HP the PC leader for Q4 2012, Canalys has a different perspective. The analyst firm has declared Apple the top PC vendor for the past quarter, thanks in part to the booming success of the iPad and the iPad mini. By Canalys's reckoning, Amazon, too, now beats out the likes of Acer and Asus as leading PC vendors, having shipped 4.6 million Kindles in Q4."
Titus Andronicus writes "LibreOffice 4.0.0 has been released. Some of the changes are for developers: an improved API, a new graphics stack, migrating German code comments to English, and moving from Apache 2.0 to LGPLv3 & MPLv2. Some user-facing changes are: better interoperability with other software, some functional & UI improvements, and some performance gains."
Hugh Pickens writes writes "Embry-Riddle Aeronautical University has announced plans to launch the nation's first ever bachelor's degree in Commercial Space Operations to supply the commercial spaceflight industry with skilled graduates in the areas of space policy, operations, regulation and certification, as well as space flight safety, and space program training, management and planning. The rapid expansion of commercial spaceflight operations is fostered by NASA's commercial cargo and crew development programs and by entrepreneurs developing capabilities for suborbital spaceflight, orbital space habitats, space resource prospecting and other commercial ventures. 'Embry-Riddle's new Commercial Space Operations degree is one of the most innovative non-engineering degrees in the aerospace industry,' says program coordinator Lance Erickson, a professor of applied aviation sciences at Embry-Riddle. 'When we were planning this degree, our advisers from the commercial space industry said they couldn't wait to hire our graduates.'"
New submitter jdela writes "Finnish Minister for Justice Anna-Maja Henriksson backs expanding FInland's child pornography blocklist to also include websites with animal porn and largely-undefined 'violent pornography.' Her proposal does not have the unanimous backing of the Finnish government, with Minister of Interior Päivi Räsänen doubting the need to expand pornography blocks. Under current law, adopted in 2006, the Finnish NBI maintains a blocklist of foreign sites linked to child pornography. This blocklist is enforced on Finnish Internet users."

chicksdaddy writes "To paraphrase a quote attributed to F. Scott Fitzgerald: 'Rich countries aren't like everyone else. They have less malware.' That's the conclusion of a special Security Intelligence Report from Microsoft, anyway. The special supplement, released on Wednesday, investigated the links between rates of computer infections and a range of national characteristics including the relative wealth of a nation, observance of the rule of law and the rate of software piracy. The conclusion: cyber security (by Microsoft's definition: low rates of malware infection) correlated positively with many characteristics of wealthy nations – high Gross Income Per Capita, higher broadband penetration and investment in R&D and high rates of literacy. It correlated negatively with characteristics common in poorer nations – like demographic instability, political instability and lower levels of education.'"
ananyo writes "How open do researchers want open-access papers to be? Apparently, not that open — when given a choice of licenses, most opt to limit the use of data and words in their open-access publications, according to figures released by the open-access journal Scientific Reports. Since July 2012 the journal has been offering researchers a choice of three types of license. The first, most liberal license, CC-BY, allows anyone, even commercial organizations, to re-use it. A more restrictive version, CC-BY-NC-SA, lets others remix, tweak and build on work if they give credit to the original author, but only for non-commercial (NC) purposes, and only if they license what they produce under the same terms (SA, or 'share-alike'). A third licence, CC-BY-NC-ND, is the most restrictive, allowing others to download and share work, but not to change it in any way (ND, 'no derivative works'), or use it commercially. The results from Scientific Reports shows that, for the 685 papers accepted by the journal, authors chose either of the more restrictive licences 95% of the time — and the most restrictive, CC-BY-NC-ND, 68% of the time."
colinneagle writes "Open Source guy Bryan Lunduke has experienced the difficulties of migrating a successful closed source project to an open license first-hand, but still believes — or at least wants to believe — that it can be done. He writes: 'Occasionally, someone makes a go of it, to take a good piece of closed source software and release the source code under a nice, open license. In fact, I did just that about a year ago. I tried to take a software development tool (along with some video games) that I had developed (and was earning a good living from) and migrate them to the GPL with continued development funded via donations. The results were...disastrous. Within a very short period of time of going Open Source, the total funding for the projects fell to less than 20% of what was being brought in via sales when the software was Closed Source, which almost completely impeded the ability to fund continued development. Luckily, I was able to recover and get things back on track, but it was definitely not a fun experience.'" How viable is migrating a closed source project to something open?
tad001 writes "CNET is reporting 'Discovered last night within a freshly jailbroken iPad: a set of buttons and code references for "radio," a feature found in iTunes on Macs and PCs, but not on the iPad or iPhone.' ... 'The buttons hint at Apple's much-rumored radio service, a product that will let people stream music much like they do on the popular Pandora service, but with deep ties to Apple's iTunes library.' ... 'The discovery follows a high-profile jailbreak of iOS 6.1, the updated system software Apple released just last week. A team of developers came up with a tool that gives users deep system-level access to do things like install applications from third-party app stores, change the look and feel of iOS, and add new software features.'"
sciencehabit writes "Left to its own devices, a bubble will weaken and pop as the fluid sandwiched between two thin layers of soap succumbs to gravity and drains toward the floor. But when researchers trapped a bubble between two platinum electrodes and cranked up the voltage, the fluid reversed direction and actually flowed up, against the force of gravity. The newly strong and stable bubbles could live for hours, and even visibly change colors as their walls grew fatter. Because soap film is naturally only nanometers thick, this whimsical experiment could help scientists create more efficient labs-on-chips, the mazes of nanotunnels that can diagnose disease based on the movements of a miniscule drop of blood."
MojoKid writes "Sony's next-generation PS4 unveil is just two weeks away, which means leaks concerning both it and Microsoft's next-generation Xbox Durango (sometimes referred to as the Xbox 720), are at an all-time high as well. Rumors continue to swirl that the next iteration of Xbox will lock out used games entirely and require a constant Internet connection. New games would come with a one-time activation code to play. Use the code, and the game is locked to the particular console or Xbox Live account it's loaded on. Physical games will still be sold (the Durango reportedly supports 50GB Blu-ray Discs), but the used game market? Kiboshed. If this is true, it's an ugly move on Microsoft's part. Not only does it annihilate the right of first sale, it'll eviscerate any game store or business that depends on video game rentals for revenue."
jfruh writes "The MPAA and other entertainment industry groups have been locked for years in a legal struggle against Newzbin2, a Usenet-indexing site. Since Newzbin2 profited from making it easier for users to find pirated movies online, the MPAA contends they can sue to take those profits on behalf of members who produced that content in the first place. But a British court has rejected that argument."
