Ian Lamont writes "A Google executive speaking at the Emerging Technology conference has described a problem that mobile phone carriers and manufacturers have been struggling with over the last few years: Users aren't taking advantage of many phones' hardware-based features. Rich Miner, Google's group manager of mobile platforms, stated that 80% of mobile phones being sold today have cameras on them, yet the number of people who actually know how to use them or get the images off the phones ranges between 10% and 50%, depending on the model. Miner listed several reasons for this state of affairs, including bad UIs and small screens, but added that the participation of companies with software expertise — including Google — would help increase usage of such features."

NASA researchers have dropped 90 rubber ducks into holes of Greenland's fastest moving glacier: the Jakobshavn Glacier in Baffin Bay. Scientists are unsure as to why glaciers speed up in the summer months. One theory is that the summer sun melts ice on the surface of the glacier, which creates pools of water, which then flow into moulins -- narrow tubular shafts in the glacier. These then transport the water from the top to the underside of the glacier. The rubber ducks, labeled with the words "science experiment" and "reward" in three languages, along with an email address, may provide some answers. It is hoped that in addition to bath time, the ducks can make a livable climate lots of fun.

arcticstoat writes "GPGPU computing has just taken a major step into the world of mainstream software development, as Adobe has now released a GPU-accelerated version of its Creative Suite, comprising Photoshop, After Effects and Premiere Pro. Both Premiere Pro and After Effects only support GPU features on Nvidia's professional range of Quadro GPUs, but Photoshop CS4 allows GPU acceleration on any mainstream GPU that supports Shader Model 3.0 (such as Nvidia's GeForce 6200 series of GPUs). Built on OpenGL, Photoshop CS4's GPU features allow real-time rotation of images and accelerated zooming and panning. As well as this, Photoshop CS4 also uses the GPU for anti-aliasing on text and objects, and it can tap the GPU for brushstroke previews, HDR tone mapping and colour conversion."

An anonymous reader writes "You've seen the Large Hadron Rap by Kate 'Alpinekat' McAlpine. Now a NASA magazine has commissioned an astrobiology rap. Jonathan Chase, aka 'Oort Kuiper', produced a six-minute YouTube rap video on astrobiology, the scientific search for extraterrestrial life. The lyrics include: 'We've been on Earth for many years and we are still producing answers; as time passes, collective knowledge advances.' This epic rap battle sees Alpinekat/CERN on top with over three million views on YouTube compared with about ten thousand for Oort Kuiper/NASA."

ThinSkin writes "Who needs a brick-and-mortar game shop when you have the world wide web of video game download services? Joel Durham Jr. over at ExtremeTech examines some game download services to decide once and for all which virtual storefront has the best deal for gamers. Among the services reviewed are: Steam, Impulse, Direct2Drive, Good Old Games, and WildTangent Orb. The most popular site in the roundup, Steam, was also the most favored because of its wide selection of popular titles, while Direct2Drive also scored top marks because it has 'just about every title in the universe.'" Which service(s) do you like the most, and what have your experiences with them been?

CWmike writes "Every June and November a new list of the world's fastest supercomputers is revealed. The latest Top 500 list marked the scaling of computing's Mount Everest — the petaflops barrier. IBM's 'Roadrunner' topped the list, burning up the bytes at 1.026 petaflops. A computer to die for if you are a supercomputer user for whom no machine ever seems fast enough? Maybe not, says Richard Loft, director of supercomputing research at the National Center for Atmospheric Research in Boulder, Colo. The Top 500 list is only useful in telling you the absolute upper bound of the capabilities of the computers ... It's not useful in terms of telling you their utility in real scientific calculations. The problem with the rankings: a decades-old benchmark called Linpack, which is Fortran code that measures the speed of processors on floating-point math operations. One possible fix: Invoking specialization. Loft says of petaflops, peak performance, benchmark results, positions on a list — 'it's a little shell game that everybody plays. ... All we care about is the number of years of climate we can simulate in one day of wall-clock computer time. That tells you what kinds of experiments you can do.' State-of-the-art systems today can simulate about five years per day of computer time, he says, but some climatologists yearn to simulate 100 years in a day."

mjasay writes "As if the proprietary software world needed any help, two business professors from Harvard and Stanford have combined to publish 'Divide and Conquer: Competing with Free Technology Under Network Effects,' a research paper dedicated to helping business executives fight the onslaught of open source software. The professors advise 'the commercial vendor ... to bring its product to market first, to judiciously improve its product features, to keep its product "closed" so the open source product cannot tap into the network already built by the commercial product, and to segment the market so it can take advantage of a divide-and-conquer strategy.' The professors also suggest that 'embrace and extend' is a great model for when the open source product gets to market first. Glad to see that $48,921 that Stanford MBAs pay being put to good use. Having said that, such research is perhaps a great, market-driven indication that open source is having a serious effect on proprietary technology vendors."

Aeonite writes "Equal parts ninja geekery and pop-cultural satire, The Ninja Handbook falls into that odd category of book that presents fiction as reality. Numerous Guides to Piracy have been published, and more than a few authors have taken a crack at Zombie Survival Guides, the most popular spin-off being the zombie novel World War Z, which is now on its way towards Hollywood. Of course, the creators of the Ask a Ninja website have taken the opposite tack here, having first staked their claim as an Internet video sensation before moving on to "old media.""

Frequent Slashdot Contributor Bennett Haselton writes "A federal judge has ruled that a school district didn't violate a student's free speech rights when it suspended her for a parody MySpace page she created calling her principal a sex addict who "hits on students". In the ruling, Judge James M. Munley made the curious argument that if the case involves a student publishing lewd and offensive speech outside of school on their own time, then the proper precedent-setting cases to look to, are cases involving students making offensive statements in school during school hours, not cases involving students making less-offensive statements outside of school on their own time. In other words, if you can't find prior caselaw where all of the factors are the same, then the lewd-speech issue is more significant than the issue of whether the speech was made in or out of school."

alphadogg writes "When you file your taxes online, you want to be sure that the Web site you visit — www.irs.gov — is operated by the Internal Revenue Service and not a scam artist. By the end of next year, you can be confident that every U.S. government Web page is being served up by the appropriate agency. That's because the feds have launched the largest-ever rollout of a new authentication mechanism for the Internet's DNS. All federal agencies are deploying DNS Security Extensions (DNSSEC) on the .gov top-level domain, and some expect that once that rollout is complete, banks and other businesses might be encouraged to follow suit for their sites. DNSSEC prevents hackers from hijacking Web traffic and redirecting it to bogus sites. The Internet standard prevents spoofing attacks by allowing Web sites to verify their domain names and corresponding IP addresses using digital signatures and public-key encryption."
