chirishnique and other readers sent in a story in AFP about a heroic supercomputer computation that has verified Einstein's most famous equation at the level of subatomic particles for the first time. "A brainpower consortium led by Laurent Lellouch of France's Centre for Theoretical Physics, using some of the world's mightiest supercomputers, have set down the calculations for estimating the mass of protons and neutrons, the particles at the nucleus of atoms. ... [T]he mass of gluons is zero and the mass of quarks is only five per cent. Where, therefore, is the missing 95 per cent? The answer, according to the study published in the US journal Science on Thursday, comes from the energy from the movements and interactions of quarks and gluons. ... [E]nergy and mass are equivalent, as Einstein proposed in his Special Theory of Relativity in 1905." Update: 11/21 15:50 GMT by KD : New Scientist has a slightly more technical look at the accomplishment.

snydeq writes "Programmers are finding themselves increasingly drawn to the Mac as a development platform, in large part due to Apple's decision to move to Intel chips and to embrace virtualization of other OSes, which has turned Mac OS X into a flexible tool for development, InfoWorld reports. The explosion of interest in smartphone development is helping the trend, with iPhone development lock-in to the Mac environment the chief motivating factor for Apple as a platform of choice for mobile development. Yet for many, the Mac remains sluggish and poorly tuned for development, with developers citing its virtual memory system's poor performance in paging data in and out of memory and likening use of the default-network file system, AFS, to engaging oneself with 'some kind of passive-aggressive torture.' What remains unclear is whether Apple will lend an ear to this new wave of Mac-based development or continue to develop products that lock out uses programmers expect."

superglaze writes to tell us that VMware has announced a large effort behind their Mobile Virtualization Platform, promising the possibility of multiple operating systems on mobile devices. "The company described MVP as a 'thin layer of software' that will be embedded in handsets and 'be optimized to run efficiently on low-power-consuming and memory-constrained mobile phones.' Asked whether MVP would offer something different from the abstraction already provided by mobile Java, VMware's European product director Fredrik Sjostedt told ZDNet UK that MVP would require less recoding. 'If you want to have an application run on a Java-specific appliance, you need to code it for Java,' Sjostedt said. 'What we're introducing with MVP is an [embedded] abstraction layer below that, between the physical hardware and the software layer.'"

An anonymous reader notes an Inquirer story reporting on something of a breakthrough in virtual machine management — a demonstration (not yet a product) of migrating a running virtual machine across CPUs from different vendors (video here). "Red Hat and AMD have just done the so called impossible, and demonstrated VM live migration across CPU architectures. Not only that, they have demonstrated it across CPU vendors, potentially commoditizing server processors. This is quite a feat. Only a few months ago during VMworld, Intel and VMware claimed that this was impossible. Judging by an initial response, VMware is quite irked by this KVM accomplishment and they are pointing to stability concerns. This sound like scaremongering to me ... All the interesting controversy aside, cross-vendor migration is [obviously] a good thing for customers because it avoids platform lock-in."

Miah Clayton writes "In the past, installing Mac OS X, Linux, and Windows on an Intel mac meant that you were forced into only having 3 usable partition slots due to the MBR/GPT hybrid limitations. Steven Noonan figured out a way to avoid dealing with the MBR partition limit and have a Linux install that isn't performance-crippled by having a swap file instead of a swap partition."

snydeq writes "Powering down servers to conserve energy is a controversial practice that, if undertaken wisely, could greatly benefit IT in its quest to rein in energy costs in the datacenter. Though power cycling's long-term effects on server hardware may be mythical, its effects on IT and business operations are certainly real and often detrimental. Yet, development, staging, batch processing, failover — several server environments seem like prime candidates for routine power cycling to reduce datacenter energy consumption. Under what conditions and in what environments does powering down servers seem to make the most economic and operational sense, and what tips do folks have to offer to those considering making use of the practice?"

alphadogg writes "The Payment Card Industry Security Standards Council, the organization that sets technical requirements for processing credit- and debit-cards, Wednesday issued revised security rules, while also indicating next year it will focus on new guidelines for end-to-end encryption, payment machines and virtualization. PCI adherence has been pushed big time in the industry to help avoid more big breaches such as the one involving TJX. Those familiar with the standard say it could be expensive to implement and that there are some things those using wireless LANs will need to pay especially close attention to."

snydeq writes "Neil McAllister cuts through VMware's marketing hype to examine the potential impact of VMware's newly pronounced 'virtual datacenter OS' — which the company has touted as the death knell for the traditional OS. Literally an operating system for the virtual datacenter, VDC OS is an umbrella concept to build services and APIs that make it easier to provision and allocate resources for apps in an abstract way. Under the system, McAllister writes, apps are reduced to 'application workloads' tailored through vApp, a tool that will allow developers to 'encapsulate the entire app infrastructure in a single bundle — servers and all.' The concept could help solve the current bugbear of programming, parallel processing, McAllister concludes, assuming VMware succeeds."

ruphus13 writes with some more news for people foretelling the death of VMware. Sun has open sourced their xVM server, their bare-metal hypervisor virtualization solution. What used to once be the cash cow for VMware is now coming under increased threat, and Sun is once again turning to the Open Source community as a weapon. "Sun xVM Server is an outgrowth of the Xen project — which raises the question of why a company would go with Sun's version rather than the Xen one. Apart from its support for SPARC and Solaris (as well as other chips and operating systems), Sun is also building a services and sales organization around a commercial version of xVM server... If you want to kick the tires or cut your costs, you can hop over to xVMServer.org, download the source (GPL 3) and join the community. But Sun is betting that, as deployments move from an initial testing phase to active usage, large organizations will be willing to pay for guaranteed support (starting at $500 per year per physical server)."

Barence writes "Microsoft is working on a web-based operating system called Midori, as it looks to life beyond Windows. Midori is expected to be a cloud-computing service, and so not as dependent on hardware as current generations of Windows. It's also expected to run with a virtualization layer between the hardware and the OS, and is expected to be a commercial offshoot of the Singularity research project which Microsoft has been working on since 2003." If this story sounds familiar to you, it probably is.

goombah99 writes "After snapping up virtualization company InnoTek at the beginning of the year, Sun has recently released VirtualBox as a fully functional and highly polished free GPL open source x86 Virtual Machine. It can host 32- or 64-bit Linux, Windows XP Vista and 98, OpenSolaris and DOS. It runs on Mac OS X, Windows, and Unix platforms. The download is just 27MB. A review of it on MacWorld, showing HD movies playing inside windows XP on a mac, demonstrates performance visually indistinguishable from VMware. Like its competition, it can run other OSes in rootless, rooted, or seamless modes display modes (where all the applications have their windows mixed at the same time). Each VM instance can only run single core (though I/O is multi-core), and it does not yet support advanced windows graphics libraries however, so some gamers may be disappointed. Slashdot discussed the InnoTek acquisition earlier.

rsiles writes "Honeynet solutions were seen just as a research technology a couple of years ago. It is not the case anymore. Due to the inherent constraints and limitations of the current and widely deployed intrusion detection solutions, like IDS/IPS and antivirus, it is time to extended our detection arsenal and capabilities with new tools: virtual honeypots. Do not get confused about the book title, specially about the "virtual" term. The main reason to mention virtual honeypots, although the book covers all kind of honeynet/honeypot technologies, is because during the last few years virtualization has been a key element in the deployment of honeynets. It has offered us a significant cost reduction, more flexibility, reusability and multiple benefits. The main drawback of this solution is the detection of virtual environments by some malware specimens." Read below for the rest of Raul's review.

Mierdaan writes "VMware's bare-metal hypervisor is available for free starting today. ESXi, which can either be installed or run from an embedded device available in certain servers, has a 32MB footprint and gives small businesses an easy way to get into the virtualization world, with easy upgrade paths to enterprise-level features such as (H)igh (A)vailability and (D)istributed (R)esource (S)cheduler. ESXi runs on most any hardware with a server-class disk controller, and previously retailed for $495. VMware is obviously shooting to prevent Microsoft's Hyper-V technology from gaining a foothold in the marketplace."

ruphus13 writes "A new Goldman Sachs IT report recently released states that IT jobs will be dramatically reduced in 2009, starting with contract and offshore developers. From the article: 'Sharp reductions likely in contract staff, professional services and hardware, and almost no investment in cloud computing.' The article goes on to say 'The CIOs indicated that server virtualization and server consolidation are their No. 1 and No. 2 priorities. Following these two are cost-cutting, application integration, and data center consolidation. At the bottom of the list of IT priorities are grid computing, open-source software, content management and cloud computing (called on-demand/utility computing in the survey) — less than 2% of the respondents said cloud computing was a priority.' Postulating a 'pointy haired boss' problem, an analyst goes on to say, '[Grid computing, Open Source and Cloud computing] require a technical understanding to get to their importance. I don't think C-level executives and managers have that understanding.' But they do control the paychecks ..."

blackbearnh writes "O'Reilly News talked to Bill Coleman, former founder of BEA and current founder and CEO of Cassett Corporation, about the challenges involved in building more energy-efficient data centers. Coleman's company is trying to change the way resources in the data center are used, by more efficiently leveraging virtualization to utilize servers to a higher degree. In the interview, Coleman touches on this topic, but spends most of his time discussing how modern data centers grossly overcool and overdeploy hardware, leading to abysmal levels of efficiency."

David Martinjak writes "Running Xen: A Hands-On Guide to the Art of Virtualization was published by Prentice Hall, and authored by Jeanna N. Matthews, Eli M. Dow, Todd Deshane, Wenjin Hu, Jeremy Bongio, Patrick F. Wilbur, and Brendan Johnson. The book, which will be referred to as simply Running Xen, was a great resource on Xen and virtualization from the administration side. A wide range of topics was covered from installing Xen all the way up to managing virtual resources, including migrating guest environments. Overall, the explanations were concise and understandable; while the information was presented in a straightforward manner. Running Xen was definitely a useful resource for administering systems with Xen." Keep reading for the rest of David's review.

Dr. Jim writes "The good folks over at the Gartner Group have revealed the top 10 technologies that they believe will change the world over the next four years. The usual suspects including multi-core chips, virtualization, and cloud computing are on the list. Multicore servers and virtualization will mean that firms will need fewer boxes, and apps can be easily moved from box to box (and right out the door to an outsourced data center). Workplace social networks and cloud computing means that the need for a centralized IT department will go away. Firms will no longer need to own/maintain the boxes that they use to run their firm's apps. With no need to touch a box, there will be no need to have the IT staff co-located with the boxes."

Joyce writes "Novell today announced the availability of SUSE Linux Enterprise 10 Service Pack 2 (SP2), containing enhancements in virtualization, management, hardware enablement and interoperability. Several improvements specific to SUSE Linux Enterprise Desktop 10 and SUSE Linux Enterprise Real Time 10 are also included. Delivering Xen version 3.2, SP2 includes several virtualization advances, including support for fully virtualized Windows Server 2008 and Windows Server 2003 and the live migration of those Windows Server guests across physical machines. Advances in high availability and storage management such as updates to Heartbeat 2 and OCFS2 are also included." And an anonymous reader points out today's release of Red Hat Enterprise Linux version 5.2, which brings "a broad refresh of hardware support and improved quality, combined with new features and enhancements in areas such as virtualization, desktop, networking, storage & clustering and security. Virtualization of very large systems, with up to 64 CPUs and 512 GB of memory, is now possible. Red Hat Enterprise Linux 5.2 Desktop includes enhanced support for laptop suspend/hibernate and resume, updated graphics drivers and a comprehensive update of desktop applications, including OpenOffice 2.3 and Firefox v3," and points out this guide for upgrading your RHEE system.

buzzardsbay writes "While technologies such as virtualization, multi-threading, and blade servers have made the data center leaner, those who work there are getting... well... not leaner. According to a new study by CareerBuilder.com, 34 percent of IT workers say they have gained more than ten pounds in their current jobs. And 16 percent say they've gained at least twice that. The culprits seem to be the stressful-yet-sedentary nature of tech work coupled with our famously poor eating habits. According to the survey, some 41 percent of IT workers eat out for lunch twice or more per week, making portion and calorie control difficult. Eleven percent buy their lunch out of a vending machine at least once a week."

For months now, I've been geeked about Amazon's EC2 as a web hosting service. But until today, in my opinion, it wasn't ready for prime time. Now it is, for two reasons. One, you can get static IPs, so if an outward-facing VM goes down you can quickly start another one and point your site's traffic to it without waiting for DNS propagation. And two, you can now separate your VMs into "physically distinct, independent infrastructure" zones, so you can plan to keep your site up if a tornado takes out one NOC. If I were developing a new website I'd host it there; buying or leasing real hardware for a startup seems silly. If you have questions, or especially if you know something about other companies' virtual hosting options, post comments -- let's compare notes.
