Lisandro sends in news that testing of the new class of superconductors we discussed a while back (compounds of iron, lanthanum, and rare earths) has turned up a major surprise: magnetism doesn't shut off the superconducting state. Magnetic fields represent one of three factors that limit expanded applications for superconductors (the others are current density and temperature dependence.) The research will appear in Nature; here's a preprint (PDF).

Roland Piquepaille writes "An international team of scientists has found a strange ring around a dead star by using images taken by NASA's Spitzer space telescope. This star, called SGR 1900+14, belongs to a class of objects known as magnetars. According to NASA, a magnetar is 'a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.' So far, about a dozen magnetars have been found. An amazing thing about these stellar objects is their magnetic field. One of the researchers said that 'magnetars possess magnetic fields a million billion times stronger than the magnetic field of the Earth.'

An anonymous reader writes "The italian economic journal 'Il sole 24 ore' published an article about a successful cold fusion experiment performed by Yoshiaki Arata in Japan. They seems to have pumped high pressure deutherium gas in a nanometric matrix of palladium and zyrcon oxide. The experiments generates a considerable amount of energy and they found the presence of Helium-4 in the matrix (as sign of the fusion). I was not able to find other articles about this but the journal is very authoritative in Italy. Google translations are also available."

jlunavtgrad writes "I recently attended an embedded engineering conference and was surprised at how many vendors were selling tools to analyze source code and scan for bugs, without ever running the code. These static software analysis tools claim they can catch NULL pointer dereferences, buffer overflow vulnerabilities, race conditions and memory leaks. Ive heard of Lint and its limitations, but it seems that this newer generation of tools could change the face of software development. Or, could this be just another trend? Has anyone in the Slashdot community used similar tools on their code? What kind of changes did the tools bring about in your testing cycle? And most importantly, did the results justify the expense?"

StarEmperor writes "A team of Canadian and German scientists have fabricated a room-temperature superconductor, using a highly compressed silicon-hydrogen compound. According to the article,"The researchers claim that the new material could sidestep the cooling requirement, thereby enabling superconducting wires that work at room temperature.""

Finallyjoined!!! sends us a BBC account of a dad who traveled to Nigeria and brought back an XO laptop for his 9-year-old, Rufus. Here is Rufus's review, a child's view of OLPC. "Because it looks rather like a simple plastic toy, I had thought it might suffer the same fate as the radio-controlled dinosaur or the roller-skates he got last Christmas - enjoyed for a day or two, then ignored. Instead, it seems to provide enduring fascination... With no help from his Dad, he has learned far more about computers than he knew a couple of weeks ago, and the XO appears to be a more creative tool than the games consoles which occupy rather too much of his time."

An anonymous reader writes "AMD has released two videos that show an overview of the new AMD Spider platform and how easy it is to overclock it with a single tool. The AMD Spider is based on AMD Phenom processors, the newly released ATI Radeon HD 3800 series discrete graphics and AMD 7-Series chipsets."

BaCa writes with a link indicating that a survey of white collar US workers shows that something like a third of all employees break IT policies. Of those, almost a sixth actually used P2P technologies from their work PCs. Overall, the survey indicates workers aren't overly concerned about any kind of security: "The telephone survey found that 65% of white-collar professionals are either not very concerned or not concerned at all about their privacy when using a workplace computer. A surprising 63% are not very concerned or are not concerned at all about the security of their information while at work. Additionally, most employees have the misconception that these behaviors pose little to no risk to their companies."

An anonymous reader writes "After 15+ years as a code monkey, mostly doing back-end systems design / development, I was surprised by recent developments at my workplace that have resulted in my being transitioned into a dual architect / managerial role within the next few weeks. While I am somewhat confident at this point in my career in my experience and training for an architect-type position, I have serious concerns about being able to properly fulfill the role as manager. Aside from 'Become a manager in 2 days' type books, what resources would you recommend I look to for guidance in this transition?"

mrneutron2004 writes "Tweaktown seems to have the first review out of the gate on AMD's flagship R600 core. 'Our focus today is solely on the HD 2900 XT 512MB GDDR-3 graphics card – it is the first GPU with a fast 512-bit memory interface but what does this mean for performance? ... After taking a look at the GPU and the card from PowerColor as well as some new Ruby DX10 screenshots, we will move onto the benchmarks and compare the red hot flaming Radeon monster against Nvidia's GeForce 8800 GTX along with the former ATI GPU king, the Radeon X1950 XTX."
