Cosmic Ray Intensity Reaches Highest Levels In 50 years
An anonymous reader writes "A NASA probe found that cosmic ray intensities in 2009 had increased by almost 20 percent beyond anything seen in the past 50 years. Such cosmic rays arise from distant supernova explosions and consist mostly of protons and heavier subatomic particles — just one cosmic ray could disable unlucky satellites or even put a mission to Mars in jeopardy."Read more of this story at Slashdot.
Nvidia Discloses Details On Next-Gen Fermi GPU
EconolineCrush writes "The Tech Report has published the first details describing the architecture behind Nvidia's upcoming Fermi GPU. More than just a graphics processor, Fermi incorporates many enhancements targeted specifically at general-purpose computing, such as better support for double-precision math, improved internal scheduling and switching, and more robust tools for developers. Plus, you know, more cores. Some questions about the chip remain unanswered, but it's not expected to arrive until later this year or early next."Read more of this story at Slashdot.
Microsoft Blocks Pirates From Security Essentials Software
CWmike writes "Microsoft will block users running counterfeit copies of Windows from installing the free Security Essentials antivirus software, said Alex Kochis, director of Microsoft's Genuine Windows team, in a post to a company blog. On-again, off-again debates about the wisdom of blocking security-oriented downloads like patches or defensive software have centered around the argument that Microsoft should protect all users, including pirates, since hijacked PCs threaten the entire Windows ecosystem. In this case, though, one analyst isn't buying that line. 'I can't see any justification for making Microsoft give away Security Essentials [to counterfeit Windows users],' said John Pescatore, Gartner's primary security analyst. 'Those people have many other choices, including free. There are plenty of alternatives to Security Essentials,' he said, adding that that makes a difference. Windows patches, on the other hand, aren't available from anyone but Microsoft."Read more of this story at Slashdot.
What To Cover In a Short "DIY Tech" Course?
edumacator writes "Our school is working hard to provide our students with relevant opportunities of study. We have a short 'seminar' period that meets three days a week for thirty minutes. I've chosen to teach a seminar on 'Home Grown Technology' even though I'm an English teacher and only an amateur techie. If you had thirty minutes, three days a week, for nine weeks, what would you teach a group of high school students? I'm considering the Wii-mote smartboard and multitouch displays, but I'm afraid I'm overreaching."Read more of this story at Slashdot.
Google Wants to Map Indoors, Too
An anonymous reader writes "Google maps are getting extended indoors next month with a new app called Micello that takes over where conventional navigators leave off — mapping your route inside of buildings, malls, convention centers and other points of interest. You don't get a 'you are here' blinking dot yet — but they do promise to add one next year using WiFi triangulation. At the introduction next month, Micello will only work in California, but they plan to expand to other major US cities during 2010."Read more of this story at Slashdot.
NVidia Cripples PhysX "Open" API
An anonymous reader writes "In a foot-meet-bullet type move, NVidia is going to disable PhysX engine if you are using a display adapter other than one that came from their company. This despite the fact that you may have an NVidia card on your system specifically to do this type of processing. 'For a variety of reasons some development expense, some quality assurance and some business reasons Nvidia will not support GPU accelerated PhysX with Nvidia GPUs while GPU rendering is happening on non-Nvidia GPUs.' Time to say hello to Microsoft dx physics or Intel's Havok engine."Read more of this story at Slashdot.
Auto-Detecting Malware? It's Possible
itwbennett writes "If antivirus protectors could collect data from machines and users, including geographic location, social networking information, type of operating system, installed programs and configurations, 'it would enable them to quickly identify new malware strains without even looking at the code,' says Dr. Markus Jakobsson. In a recent article, he outlines some examples of how this could work. The bottom line is this: 'Let's ignore what the malware does on a machine, and instead look at how it moves between machines. That is much easier to assess. And the moment malware gives up what allows us to detect it, it also stops being a threat.'"Read more of this story at Slashdot.
Oracle Fined For Benchmark Claims
pickens writes "Information Week reports that the Transaction Processing Council, which sets benchmarks for measuring database performance, has fined Oracle $10,000 for Oracle's ads published August 27 and September 3 on the front page of the Wall Street Journal which violate the 'fair use' rules that govern TPC members by 'comparing an existing TPC result to something that does not exist.' The ads said to expect a product announcement on October 14 that would demonstrate that some sort of hybrid Oracle-Sun setup would offer two-digit performance on the TPC-C online transaction processing test compared to IBM's 6 million transaction per minute result on its Power 595 running AIX and DB2. The TPC Council serves as a neutral forum where benchmark results are aired and compared. 'At the time of publication, they didn't have anything' submitted to the council says Michael Majdalany, administrator of the council adding that that Oracle is free to use TPC numbers once it submits an audited result for the Sun-Oracle system. Fines by the TPC are infrequent, with the last action — a $5,000 fine — levied against Microsoft in 2005 for unsupported claims about SQL Server. 'It takes a fairly serious violation to warrant a member being fined,' says Majdalany."Read more of this story at Slashdot.
GPS Receiver Noise Can Be Used To Detect Snow Depth
cremeglace writes "Scientists at the University of Colorado at Boulder have found a use for GPS besides finding restaurants or the occasional road-that-doesn't-exist: it can be used to measure snow depth. The new technique, which takes advantage of distortions of the GPS signal after it reflects off the snowpack, may potentially improve weather forecasts by allowing meteorologists to track snowfall patterns. ScienceNOW has the story, which one geophysicist describes as 'a classical case of one person's noise becoming another person's signal.'"Read more of this story at Slashdot.
Dam Burst Tool Disables China's Green Dam Censorware
An anonymous reader writes "The infamous Green Dam censorship software has suffered yet another blow. As ZDNet explains, Dam Burst, a tool released by security researcher Jon Oberheide, allows unprivileged users to disable the censorware by removing the hooks that enable it to monitor and block user activity, effectively restoring running applications to their original uncensored state. While the Dam Burst software is currently available at Oberheide's website, community mirrors will undoubtedly be necessary to avoid blocking by the Great Firewall."Read more of this story at Slashdot.
US Relaxes Control Over ICANN
An anonymous reader tips news that the US Dept. of Commerce has signed an agreement with ICANN to end their current oversight responsibilities and allow more input from the global community. "The move comes after European regulators and other critics have said the US government could wield too much influence over a system used by hundreds of millions of people worldwide. Those critics have complained, among other things, about the slow rollout of Internet addresses entirely in languages other than English." The US will still be involved; every three years, ICANN's work will be evaluated by a committee, one member of which will be from the Dept. of Commerce.Read more of this story at Slashdot.
Using Aluminum Oxide Paint To Secure Wi-Fi
eldavojohn writes "The BBC reports on people using aluminum oxide in their paint to block Wi-Fi signals from leaving their home or business. Aluminum oxide resonates at the same frequency as Wi-Fi signals and other radio waves, blocking data from going outside a building. It's not a flawless solution, as it may also block AM/FM signals. You or your neighbors may be unwittingly using this already, as most pre-finished wood flooring uses aluminum oxide as a protective coating."Read more of this story at Slashdot.
Company Uses DMCA To Take Down Second-Hand Software
dreemteem writes "A judge Tuesday heard arguments in a dispute over software sales that could potentially have repercussions on the secondhand sale of virtually any copyrighted material. The suit was filed by Timothy Vernor, a seller on eBay, after Autodesk, citing the Digital Millennium Copyright Act, asked eBay to remove some of its software products that Vernor had listed for sale there, and later to ban him from the site. Vernor had not illegally copied the software but was selling legitimate CDs of the products secondhand. For that reason, he argued, he was not infringing Autodesk's copyright. Autodesk countered that because it licenses the software, rather than selling it outright, a licensee does not have the right to resell its products."Read more of this story at Slashdot.
Federal Summit Eyes Crackdown On Texting While Driving
suraj.sun sends along this quote from an Associated Press report: "Opening a government meeting on auto safety, the Obama administration reported Wednesday that nearly 6,000 people were killed and a half-million injured last year in vehicle crashes connected to driver distraction, a striking indication of the dangers of using mobile devices behind the wheel. The Transportation Department was bringing together experts over two days for what it's calling a 'distracted driving summit' to take a hard look at the highway hazards caused by drivers talking on cell phones or texting from behind the wheel. ... Driver distraction was involved in 16 percent of all fatal crashes in 2008. Eighteen states and the District of Columbia have passed laws making texting while driving illegal and seven states and the district have banned driving while talking on a handheld cell phone, according to the Insurance Institute for Highway Safety. Many safety groups have urged a nationwide ban on texting and on using handheld mobile devices while behind the wheel."Read more of this story at Slashdot.
Artificial Heart Recipient Has No Pulse
laggist writes "A heart patient in Singapore has been implanted with an artificial heart that pumps blood continuously, allowing her to live without a pulse. From the article: '... the petite Madam Salina, who suffers from end-stage heart failure, would not have been able to use the older and bulkier models because they can only be implanted in patients 1.7m or taller. The 30-year-old administrative assistant is the first recipient here to get a new artificial heart that pumps blood continuously, the reason why there are no beats on her wrist.'" The story is light on details, but an article from last year in MIT's Technology Review explains a bit more about how a pulse-less artificial heart works.Read more of this story at Slashdot.
