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."

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."

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."

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.

One of the more interesting conversations Tim Lord had at 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.

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.'"

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?

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."
