swsuehr writes "The Book of Xen: A Practical Guide for the System Administrator provides an excellent resource for learning about Xen virtualization. I frequently need to create test environments for examples that appear in various books and magazine articles (in the interest of full disclosure, I've never written for the publisher of this book). In the days before virtualization that meant finding and piecing together hardware. Like many readers, I've been using virtualization in one form or another for several years, including Xen. This book would've saved hours searching around the web looking for tidbits of information and sifting through what works and doesn't work in setting up Xen environments. The authors have done the sifting for me within the ~250 pages of the book. But far beyond, the authors also convey their experience with Xen using walkthroughs, tips, and recommendations for Xen in the real world." Read on for the rest of Steve's review.

theodp writes "In the world envisioned by Microsoft's just-published patent application for Social Marketing, monopolists will maximize revenue by charging prices inversely related to the perceived influence an individual has on others. Microsoft gives an example of a pricing model that charges different people $0, $5, $10, $20, or $25 for the identical item based on the influence the purchaser wields. A presentation describing the revenue optimization scheme earned one of the three inventors applause (MS-Research video), and the so-called 'influence and exploit' strategies were also featured at WWW 2008 (PDF). The invention jibes nicely with Bill Gates's pending patents for identifying influencers. Welcome to the brave new world of analytics."

Charbax writes "Last April, Microsoft argued that it controlled the netbook OS market for devices sold in certain Microsoft-friendly US retail stores, while ABI Research claims that Linux actually has 32% of the worldwide netbook market, and that its market-share is growing. At the recent Netbook World Summit in Paris France, Aaron J. Seigo, Community leader at the KDE Foundation, and Arnaud Laprévote, CTO at Mandriva Linux, give us their estimation for next year's Linux market share (video) in the consumer laptop market. Their estimation is that Linux will dominate in ARM-powered laptops and that those may take over a significant share of the overall laptop market by their significantly cheaper prices (as low as $80), longer battery life (as long as 20-40 hours on a small battery using the Pixel Qi screens), as well as lower size and weight. Running some of the Chromium OS builds for ARM available shortly and having a full browser experience on those cheaper and better ARM-powered Linux laptops could make it a significant mass market success to shake up the Intel and Microsoft consumer PC/laptop monopoly in its boots."

TopSpin writes "NASA's Constellation Program and Ares rockets appear to have strong support in Congress. An appropriations bill passed by the House includes language that bars 'any efforts by NASA to cancel or change the current Constellation program without first seeking approval of Congress.' The Administration's appointed NASA leadership is being publicly hostile towards its traditional aerospace affiliations. As Charles Bolden put it to industry execs, 'We are going to be fighting and fussing over the coming year,' and 'Some of you are not going to like me because we are not going to do the same kind of things we've always done.'"

MojoKid writes "Samsung is betting there's room for more in the smartphone market and has unveiled its new bada OS. The name 'bada,' means 'ocean' in Korean and was chosen to convey the 'limitless variety of potential applications which can be created using the new platform.' Samsung claims the OS is extremely simple for developers, saying that bada was built to be extremely interactive with its users — including flash control, motion sensing, fine-tuned vibration control and face detection. Samsung is hoping developers will take this user interface and create a variety of applications focused around it, and thus provide different types of apps than exist for the iPhone and Android OS. The bada OS has a variety of sensors, including accelerometers, tilt, weather, proximity and activity. Samsung will be hosting a series of Developer Days in Seoul, London and San Francisco, among other cities, throughout 2010."

dcblogs writes "IBM has released a new mainframe server that doesn't include its z/OS operating system. This Enterprise Linux Server line supports Red Hat or Suse. The system is packaged with mainframe management and virtualization tools. The minimum processor configuration uses two specialty mainframe processors designed for Linux. IBM wants to go after large multicore x86 Linux servers and believes the $212,000 entry price can do it."

wkurzius writes with this nugget from Mac Rumors: "As anticipated, Google has finally released an official beta version of its Chrome browser for Mac. The initial beta version, termed Build 4.0.249.30, requires Mac OS X Leopard or Snow Leopard, and is only compatible with Intel-based Macs." And hierofalcon writes with word that Chrome has also been made available as an official Linux Beta.

snydeq writes "InfoWorld's Mel Beckman conjectures on the functionality necessary to make the Google 'smartbook dream' a reality, prioritizing the features any smartphone/netbook hybrid would require to succeed. From multitouch, to SSDs, to dual-boot capabilities, the list goes beyond what early Android-based entrants have to offer but remains within the realm of possibility, especially if Google CEO Eric Schmidt's hints at a future Chrome/Android OS convergence come to pass."

harrymcc writes "Barnes & Noble's Nook — the most significant e-reader since Amazon's original Kindle — hits B&N's retail stores today. I've published an extensive review of the device, which is also the first e-reader to run Google's Android OS: It's an interesting and capable gadget in many ways, but the interface — which is sluggish and somewhat quirky — isn't polished enough to render it a Kindle killer."

Sharky2009 writes "VMware is developing virtualisation for smartphones which can run any two OSes — Windows Mobile, Android or Linux — at once. The idea is to have your work applications and home applications all running insider their own VMs and running at the same time so you can access any app any time. VMware says: 'We don't think dual booting will be good enough — we'll allow you to run both profiles at the same time and be able to switch between them by clicking a button,' he said. 'You'll be able to get and make calls in either profile – work or home – as they will both be live at any given point in time.'" Also mentioned in February of this year, but now the company's announced a target of 2012 for mass production.

dnaumov writes "FreeNAS, a popular, free NAS solution, is moving away from using FreeBSD as its underlying core OS and switching to Debian Linux. Version 0.8 of FreeNAS as well as all further releases are going to be based on Linux, while the FreeBSD-based 0.7 branch of FreeNAS is going into maintenance-only mode, according to main developer Volker Theile. A discussion about the switch, including comments from the developers, can be found on the FreeNAS SourceForge discussion forum. Some users applaud the change, which promises improved hardware compatibility, while others voice concerns regarding the future of their existing setups and lack of ZFS support in Linux."

adeelarshad82 writes "Truly open-development, open-source phones like the Nokia N900 will never hit the mainstream in the US because wireless carriers in the country hate the unexpected, writes PCMag's Sascha Segan. The open-source philosophy is all about unexpected, disruptive ideas bubbling upwards, and that drives network planners nuts. So, you get unsatisfactory hybrids like Google Android, which uses some open-source components but locks third-party developers into a crippled Java sandbox. The bottom line is that while Linux the OS, the kernel, and the memory manager are attractive to phone manufacturers, Linux the philosophy — and users banding together ad hoc to create new things — is anathema to wireless carriers."

Barence writes to mention that Nokia is giving users a first glimpse at what promises to be a completely overhauled Symbian user experience this coming year. Nokia's chief exec blamed the user interface — as opposed to the OS itself — as the root problem. "The company will roll out a completely re-engineered user interface in 2010, aimed at addressing many of the criticisms associated with the OS. 'We will reduce the clutter and improve the input methods including multi-touch and single tap,' Kallasvuo told delegates. 'It should be just two taps to get to your favorite music or videos, rather than eight. We'll improve browser experience so that it's a quicker, flash improved, media experience with pinch-to-zoom and so on.' And, Kallasvuo wasn't stopping there. Aside from completely redesigning the interface, he also suggested that future Symbian OSes would be much faster."

Zordak writes "US patent 6,631,400 claims a method of making sure enough people get your spam. A federal district court had overturned the patent as anticipated and obvious, and not drawn to patentable subject matter. The Federal Circuit, the appeals court which hears patent matters, upheld the finding of obviousness, thus invalidating the patent."

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."

necro81 writes "The NY Times is reporting on a new study from Osram, a German lighting manufacturer, which has calculated the total lifecycle energy costs of three lightbulb technologies and found that both LEDs and CFLs use approximately 20% of the energy of incandescents over their lifetimes. While it is well known that the newer lighting technologies use a fraction of the energy of incandescents to produce the same amount of light, it has not been proven whether higher manufacturing energy costs kept the new lighting from offering a net gain. The study found that the manufacturing and distribution energy costs of all lightbulb technologies are only about 2% of their total lifetime energy cost — a tiny fraction of the energy used to produce light." The study uses the assumption that LEDs last 2.5 times longer than CFLs, and 25 times longer than incandescents.

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."

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.

Charbax writes "While Archos' current 'Archos 5 Internet Tablet with Android' is a 4.8" WVGA tablet that runs Android 1.5 (and perhaps 2.0 soon with the full Google Marketplace Experience), users of last year's 4.8" and 7" Archos Linux tablets have been complaining that Archos' firmware updates to its proprietary, embedded Linux OS were too infrequent, and added too little of the requested functionality. Under pressure from hackers demonstrating jailbreak methods, Archos has just now officially released (PDF) the open-source Special Developer Edition firmware based on Angstrom Linux, generated from a customized, open embedded build for last year's Archos 5 and 7 Internet Media tablets. If many talented developers join the community of Archos hackers to make software for this new Archos SDE firmware, then Android, Angstrom Linux, Maemo Mer, Qt and Ubuntu Linux could be expected to run smoothly on it soon. That could make it the ultimate pocket Linux Internet tablet for Linux hackers. Installing Archos' new SDE firmware permanently disables DRM playback and voids the warranty."
