CWmike writes "Microsoft's Windows ran to stay in place last month as Window 7's market share gains made up for the largest-ever declines in Windows XP and Vista, data released today by Web metrics firm Net Applications showed. By these numbers, Windows 7's gains were primarily at the expense of Windows XP. For each copy of Vista replaced by Windows 7 during November, more than six copies of XP were swapped out. Meanwhile, Apple's Mac OS X lost share during November... betcha Ballmer is having an extra giddy time with that news. Linux came up a winner last month, returning to the 1% share mark for the first time since July. Linux's all-time high in Net Applications' rankings was May 2009, when it nearly reached 1.2%."

MojoKid sends in a piece that takes a step back from Google's much-analyzed OS to look at what it is trying to accomplish. "Last week, Google open-sourced its Chromium OS project, more than a year before the operating system is scheduled for release. In doing so, Google hopes a variety of developers and companies will become involved in the project, and has pledged to release regular updates as well as a comprehensive log of bug reports and fixes. This article takes a look at Google's design vision for Chromium, the unique benefits it offers, and a bit of why Google is throwing its hat into this particular ring in the first place. Chromium, after all, is a Linux-based OS entering the smartbook/netbook market at a time when the product segment is already being well served by a variety of Linux distros, XP, and Windows 7. In the midst of all these options, do we need another operating system? We just might."

RasputinAXP writes "Verizon has changed their FiOS AUP effective yesterday, and added an interesting new clause to their specific examples that we're all familiar with: 'it is a violation of the Agreement and this AUP to ... post off-topic information on message boards, chat rooms or social networking sites.' At this point, every FiOS-based Slashdot user is breaking the new AUP."

duguk writes "Microsoft has confirmed that it is investigating a problem described as the 'black screen of death,' which affects Windows 7 — and reports suggest it affects Vista and XP, too. The firm said it was looking into reports that suggest its latest security update, released on Tuesday 25 November, caused the problem. The error means that users of Windows 7 and earlier operating systems see a totally black screen after logging on to the system." Update: 12/01 22:35 GMT by KD : Microsoft now says that its November Windows updates are not causing the BlackSOD: "The company has found those reports to be inaccurate and our comprehensive investigation has shown that none of the recently released updates are related to the behavior described in the reports."

theodp writes "Over at CNET, James Urquhart sings the praises of cloud computing, encouraging folks to 'really listen to what is being said, understand how the cloud is being used, and seriously evaluate how this disruptive model will change your projects, your organization, and even your career.' Fair enough. Over at the Google Docs Help Forum, some perplexed cloud computing users spent the month of November unsuccessfully trying to figure out why they've been zinged for inappropriate content. Among the items deemed inappropriate and unshareable include notes on Henry David Thoreau ('the published version of this item cannot be shared until a Google review finds that the content is appropriate'), homework assignments, high school yearbook plans, wishlists, documents containing botanical names for plants, a list of websites for an ecommerce class, and a list of companies that rent motorcycles in Canada. When it comes to support in the cloud, it kind of looks like you might get what you pay for."

Barence writes "Microsoft Research has found a novel way of beating the deplorably slow speeds of mobile broadband, by combining several phones together to make one high-speed hotspot. Dubbed Cool-Tether, the system harnesses the mobile data connection of multiple mobile handsets to build an on-the-fly Wi-Fi hotspot. 'To address the challenges of energy efficiency, Cool-Tether carefully optimises the energy drain of the WAN (GPRS/EDGE/3G) and Wi-Fi radios on smartphones,' Microsoft's research paper claims. 'We prototype Cool-Tether on smartphones and, experimentally, demonstrate savings in energy consumption between 38%-71% compared to prior energy-agnostic solutions.'"

Arguendo writes "Martin Goetz, who obtained the first software patent in 1968, has penned a thoughtful defense of software patents for Patently-O. Goetz argues that there is no principled difference between software and hardware patents and that truly patentable software innovations require just as much ingenuity and advancement as any other kind of patentable subject matter. The Supreme Court is of course currently considering whether to change the scope of patentable subject matter in the Bilski case, which we've discussed before." Does it weaken Goetz's argument that his description of the software lifecycle harks back to the waterfall days and bears little resemblance to current development practice in open source and/or Internet contexts?

jvillain writes "India is about to pull the plug on 25 million cell phones in the name of fighting terrorism and fraud. 'The ban by India's Department of Telecommunications has been unfolding gradually since Oct. 6, 2008, six weeks before the attacks in Mumbai killed 173 people and wounded 308. A memo then directed service providers to cut off cellphone users whose devices didn't have a real IMEI — or unique identity number — in the interests of 'national security.' Since then, the move has picked up steam as a way to circumvent terrorists using black market, unregistered cellphones. The Mumbai attackers kept in touch with each other via cellphones and used GPS to pinpoint their attacks, which started Nov. 26, 2008, and went on for three days. The telecommunications department has issued warnings and deadlines through 2009 but has announced this one is for real, telling operators to block cellphones without valid IMEI numbers. Previously, it warned companies to stop importing them and customers to stop buying them.'"

miller60 writes "'Google is seeking to patent a system that provides precision cooling inside racks of servers, automatically adjusting to temperature changes while reducing the energy required to run chillers.' The cooling design uses an adjustable piping system featuring 'air wands' that provide small amounts of cold air to components within a server tray. The cooling design, which could help Google reduce the power bill for its servers, reinforces Google's focus on data center innovation as a competitive advantage. Check out the patent application and a diagram of the system."

Ponca City, We love you writes to tell us that a new software approach to police sketch artists is finding surprising success in a trial run of 15 police departments in the UK and a few other sites. The software borrows principles from evolution with an interactive genetic algorithm that progressively changes as witnesses try to remember specific details. Current field trials are reporting an increase in successful identification by as much as double conventional methods. A short video with a few working shots of the new "EFIT-V" system is also available on YouTube. "[Researcher Christopher Solomon]'s software generates its own faces that progressively evolve to match the witness' memories. The witness starts with a general description such as 'I remember a young white male with dark hair.' Nine different computer-generated faces that roughly fit the description are generated, and the witness identifies the best and worst matches. The software uses the best fit as a template to automatically generate nine new faces with slightly tweaked features, based on what it learned from the rejected faces. 'Over a number of generations, the computer can learn what face you're looking for,' says Solomon. The mathematics underlying the software is borrowed from Solomon's experience using optics to image turbulence in the atmosphere in the 1990s."

The LHC has become the world's highest-energy particle accelerator, weighing in at over one trillion electron volts. "Until now the LHC had been operating at a relatively low energy of 450 billion electron volts. On Sunday, engineers increased the energy of this 'pilot beam,' reaching 1.18 trillion electron volts at 2344 GMT. The previous record of 0.98 trillion electron volts has been held by the Tevatron accelerator since 2001. The LHC is eventually expected to operate at some seven trillion electron volts."

adeelarshad82 writes "Michael Arrington announced the death of the CrunchPad on Monday morning in a blog post heavily spiced with angst and drama. According to Arrington, the Crunchpad, a 12-inch Web tablet expected to be priced at about $300, was just days away from launch. At the last minute, however, Arrington received an email from Chandra Rathakrishnan, the chief executive of manufacturing partner Fusion Garage, apparently trying to cut Arrington out of the product on the eve of the launch. Fusion Garage, according to Arrington, wanted to market the device itself under its own name; which obviously was the deal breaker. Arrington claims that the company had overcome obstacles at every stage in the business such as deals with Intel, retail launch, securing venture capital and angel investments. Interesting bit is that some were already speculating that the Crunchpad was not real."

blackbearnh writes "The work of making high-volume web sites perform well is an ongoing challenge, and one that continues to evolve as the nature of web content changes. According to Google Performance Guru Steve Souders, fat JavaScript libraries and rich content are creating new problems for web site tuning, but one of the biggest problems lies outside the control of web site administrators — ad servers. In an interview previewing the upcoming Velocity Online conference run by O'Reilly, Souders talks at length about the real causes of poor web performance today, and in particular, the effect that poorly performing ad servers are creating. 'We adopted a framework of inserting ads, of creating ads, that's pretty simple. And because it's pretty simple, it's not highly tuned. That's one reason why we shouldn't be too surprised that we see performance issues in third party ads. The other reason is that ad services are not focused on technology. Certainly companies like Yahoo and Google and Microsoft, we're technology companies. We focus on technology. So it's not surprising that our web developers are on the leading edge of adopting these performance best practices. And it's also not surprising that ad services might lag two, three or four years behind where these web technology companies are.'"

eldavojohn writes "With the problem of moving conventional rocket fuel to the Moon and Mars on their minds, researchers from Purdue and Penn State successfully tested and demonstrated the use of aluminum-ice (ALICE) as fuel. In a paper from last August they outlined how it would work (PDF), and now they know it does. Space.com also has more information on the paper and how nano-scale aluminum functions as a fuel."

An anonymous reader recommends a piece up at Augmented Planet that makes a couple of points about privacy in the realm of geotagging and augmented reality that haven't been discussed much. First, once you geotag and upload, say, a photo to the Net you can lose ownership over the data and especially its metadata. Second, data on the Net is long-lived and might be put together in ways you wouldn't like, long after it was created. "If you geotag a picture with your new 50" plasma TV in the background and upload it to the Web, congratulations you have just told everyone where you live and what you have of value. The web has a long memory — geotag something today and in six months it is still on the Web. When you tweet from the beach in Barbados telling your friends you are away for 2 weeks, that picture of your 50" plasma will still be out there along with its location. It's easy to track down someone's home address if you have their real name." The submitter adds, "I never really cared about my online privacy too much. This article made me think seriously about privacy for the first time. No mean feat."

CNET's Crave has up a detailed interview with Last.fm's Matthew Ogle, the company's head of Web development. Reader CNETNate notes that Last.fm has streamed 275,000 years of audio around the world. From the interview: "We stream all music directly off our servers in London. We have a cluster of streaming nodes including a bunch of powerful machines with solid-state hard drives. We have a process that runs daily which finds the hottest music and pushes those tracks on to the SSDs streamers that sit in front of our regular platter-based streaming machines. That way, if someone is listening to one of our more popular stations, the chances are really good that these songs are coming off our high-speed SSD machines. They're fast because every song is sitting in memory instead of being on a slow, spinning platter." The interview is actually on two pages but pretends it's on three.

Hugh Pickens writes "Numerous high-tech devices have been proposed to help ships cope with piracy on the high seas. Now a company has developed a ship-borne launching device that fires a net or coiled rope into the path of pirate vessels using compressed air with a range of up to a range of 400m. The payload net or rope, which has a parachute attached to the end, will unravel and lay out across the surface of the water so that as the pirate boat travels through the water its propeller shaft will pick up the line and become entangled. 'With the trials and testing we've done, it has taken us some 45 minutes to cut and disentangle the line from the propeller itself,' says Jonathan Delf. 'Within that time of course, the target ship is on its way and hopefully help has arrived in the form of naval forces or helicopter support.' The system can be fired up to five times off just a cylinder of air like a simple scuba tank." The video mentions that the device can also fire a payload of golf balls. The systems have recently been sold to "several large shipping companies that travel near the oil-rich Nigerian Delta, which, like the Somalian coast, is rife with piracy."

Many readers are submitting stories related to Google Chrome OS. ruphus13 points out a GigaOm opinion piece about how, if users end up rejecting its current cloud-only focus, the nascent OS may succeed as a netbook secondary operating system alongside Windows (in company with secondaries based on other Linux flavors, including Android). Engadget reviews a Chrome OS on a USB key setup that is claimed to offer eye-opening performance compared to running under virtualization. And an anonymous reader notes the 0.1 beta release of ChromeShell, which installs a "Chrome OS-like" environment that boots to the Chrome browser in ~3 seconds; users can switch to Windows later as desired.

mssmss writes "Has anyone used G-WAN — a free (as in beer), supposedly fast and scalable Web server? The downside is it supports only C scripts, which the author claims is a plus since most programmers know C anyway. There is currently only a Windows release and no clear answer in their FAQs whether there would be Linux/Solaris releases. As an interesting aside, releasing a Web server while at the same time fighting a losing battle (PDF) with a large bank over a piracy claim of $200 million (the bank is alleged to have done the piracy) is quite a feat."

thetinytoon writes "German federal president Horst Köhler has refused to sign a law to block child pornography that passed Parliament earlier this year, stating that he 'needs more information.' In Germany, the federal president has the right to reject a law only if its passage violated the order mandated by the constitution, or if it is obviously unconstitutional — he can't veto a law simply because he disagrees with it. The law was passed under a coalition government, but a different coalition took power before the law reached the president's desk. Political observers guess that the political parties would like to get rid of the law without losing face, but since it has already passed the Parliament, they can't simply abandon it."
