Microsoft To Support CentOS Linux In Hyper-V 291

jbrodkin writes "Long the enemy of Linux users, Microsoft is apparently seeing dollar signs in the Linux-dominated Web server market. Microsoft's virtualization software, Hyper-V, will immediately add support for CentOS Linux, a community version of Red Hat that even Microsoft notes is a 'popular Linux distribution for hosters.' 'This enables our Hosting partners to consolidate their mixed Windows + Linux infrastructure on Windows Server Hyper-V,' Microsoft said. In addition to Web hosting, this targets another area where Microsoft is stuck in second place: the virtualization market dominated by VMware."

The Decline and Fall of System Administration 500

snydeq writes "Deep End's Paul Venezia questions whether server virtualization technologies are contributing to the decline of real server administration skills, as more and more sysadmins argue in favor of re-imaging as a solution to Unix server woes. 'This has always been the (many times undeserved) joke about clueless Windows admins: They have a small arsenal of possible fixes, and once they've exhausted the supply, they punt and rebuild the server from scratch rather than dig deeper. On the Unix side of the house, that concept has been met with derision since the dawn of time, but as Linux has moved into the mainstream — and the number of marginal Linux admins has grown — those ideas are suddenly somehow rational.'"

Google x86 Native Browser Client Maybe Not So Crazy After All 332

GMGruman writes "Google's experimental technology to run native x86 binaries in the browser shows lots of potential, writes Neil McAllister. He's previously said it was a crazy idea, but a new version of Native Client (NaCl) caused McAllister to take a fresh look, which has led him to conclude the technology is crazy like a fox. McAllister explains what NaCl is useful for, how to use it, and why it's not a Java or a Flash or a JavaScript replacement, but something else."

Behind-The-Scenes Superbowl Tech 154

jfruhlinger writes "You might be a hardcore sports fan or might think of jocks with disdain, but if you're a geek you'll probably be intrigued by the tech behind the brand-new stadium where this weekend's Superbowl will be played. 84 Cisco access points, 70 wiring closets, 40,000 wired ports, 8 million feet of Ethernet cabling, 260 miles of fiber, 100 TB of storage — all on a single network."

Thin Client, Or Fat Client? That Is the Question 450

theodp writes "If virtual desktops are so great, asks Jonathan Eunice, then why isn't everyone using them? However encouraged folks are by the progress virtual desktop infrastructure (VDI) has made, and however enthused they may be about extending the wins of server virtualization over into the desktop realm, you don't see analysts and developers eating the virtual desktop dog food. And even the folks you meet from Citrix, Microsoft, Quest, VMware, and Wyse — the people selling VDI — use traditional 'fat' notebooks. So, are you using virtual desktops? Why, or why not?" I wonder how long the abbreviation VDI will stick around.

Openwall Linux 3.0 — No SUIDs, Anti-Log-Spoofing 122

solardiz writes "Openwall GNU/*/Linux (or Owl for short) version 3.0 is out, marking 10 years of work on the project. Owl is a small, security-enhanced Linux distro for servers, appliances, and virtual appliances. Two curious properties of Owl 3.0: no SUID programs in the default install (yet the system is usable, including password changing); and logging of who sends messages to syslog (thus, a user can't have a log message appear to come, say, from the kernel or sshd). No other distro has these. Other highlights of Owl 3.0: single live+install+source CD, i686 or x86_64, integrated OpenVZ (host and/or guest), 'make iso' & 'make vztemplate' in the included build environment, ext4 by default, xz in tar/rpm/less, 'anti-Debian' key blacklisting in OpenSSH. A full install is under 400 MB, and it can rebuild itself from source."

Android Phones Get Virtualization 122

bednarz writes "VMware is teaming with LG to sell Android smartphones that are virtualized, allowing a single phone to run two operating systems, one for business use and one for personal use. A user's personal email and applications would run natively on the Android phone, while a guest operating system contains the employee's work environment. The devices would also have two phone numbers."

Want an IT Job? Add 'Cloud' To Your Buzzword List 187

jfruhlinger writes "There was a predicted uptick in IT hiring for late this year, but it's mid-November and it hasn't happened yet. Kevin Fogarty does see growth in one area, though: cloud and virtualization experts are being fought over, lured away from in-house jobs to cloud consultancies popping up everywhere."

Oracle Solaris 11 Express Released 160

comay writes "Today Oracle released Solaris 11 Express 2010.11. It includes a large number of new features (PDF) not found in either Oracle Solaris 10 or previous OpenSolaris releases, including ZFS encryption and deduplication, network-based packaging and provisioning systems, network virtualization, optimized I/O for NUMA platforms and optimized platform support including support for Intel's latest Nehalem and SPARC T3. In addition, Oracle Solaris 10 support is available from within a container/zone so migration of existing systems is greatly simplified." Reader gtirloni adds, "Oracle also announced that this is not a beta or preview, but a full, supported release aimed at everybody developing, testing, prototyping or demonstrating applications running on the latest Solaris release (not allowed to be used in production)."

Recommendations For Home Virtualization? 384

An anonymous reader writes "I'll have to upgrade my home computers sometime in the next few months and I'm thinking it's time to swallow the virtualization pill. Besides the ease of switching between Windows and Ubuntu, I'm looking mainly for the ability to save machine state in order to be able to revert to a known working state. Googling turns up mostly guides from 2009 and earlier. Is VMWare ESX pretty much the way to go? Performance does matter — not for gaming but I am heavily into photography, so apps like Lightroom and Photoshop need to run well. Thanks for any insight."

The Big Promise of 'Big Data' 78

snydeq writes "InfoWorld's Frank Ohlhorst discusses how virtualization, commodity hardware, and 'Big Data' tools like Hadoop are enabling IT organizations to mine vast volumes of corporate and external data — a trend fueled increasingly by companies' desire to finally unlock critical insights from thus far largely untapped data stores. 'As costs fall and companies think of new ways to correlate data, Big Data analytics will become more commonplace, perhaps providing the growth mechanism for a small company to become a large one. Consider that Google, Yahoo, and Facebook were all once small companies that leveraged their data and understanding of the relationships in that data to grow significantly. It's no accident that many of the underpinnings of Big Data came from the methods these very businesses developed. But today, these methods are widely available through Hadoop and other tools for enterprises such as yours.'"

Skills Needed For a Future In IT 258

Lucas123 writes "An increase in the pace of change in IT has created new dynamics for jobs involving the Web, mobile computing and virtualization. For those looking to enter the marketplace in years to come, 30-somethings hoping to upgrade their skills, or those who'll be winding their careers down by 2020, skill sets are drastically changing. For example, graphics chips are doubling in capacity every six months. That translates into a thousandfold increase in capacity over a five-year period — the average shelf life of most game platforms. 'We've never seen anything like it in any industry.' Colleges are in continual catch-up mode and have only recently added project management and soft skills training to computer science programs. According to one expert, 'They're about five years behind where they need to be.'"

Extreme Memory Oversubscription For VMs 129

Laxitive writes "Virtualization systems currently have a pretty easy time oversubscribing CPUs (running lots of VMs on a few CPUs), but have had a very hard time oversubscribing memory. GridCentric, a virtualization startup, just posted on their blog a video demoing the creation of 16 one-gigabyte desktop VMs (running X) on a computer with just 5 gigs of RAM. The blog post includes a good explanation of how this is accomplished, along with a description of how it's different from the major approaches being used today (memory ballooning, VMWare's page sharing, etc.). Their method is based on a combination of lightweight VM cloning (sort of like fork() for VMs) and on-demand paging. Seems like the 'other half' of resource oversubscription for VMs might finally be here."

Irish Gov't Invests In Color-Coded Fiber Optics 129

c0mpliant writes "The Irish government has invested a further €5 million, after already having invested €5 million one year ago, in a new system of fiber optics which heralds an era of virtualization of fiber networks, using color coding to enable multiple fiber providers to serve businesses and homes, often on a single strand of fiber. The technology, which has already sparked interest from companies such as BT and IBM, is already in its first phase and boasts an impressive 2.5 terabytes capacity, double the capacity of the London phone system. The company behind the technology, Intune Technology, is comprised of a group of ex-UCD photonics researchers and has been around since 1999 and are based in Dublin. The project is set to be completed by 2020."

Half of Windows 7 Machines Running 64-Bit Version 401

nk497 writes "Microsoft has said that nearly half of machines running Windows 7 are using the 64-bit version, up from just 11% of PCs running Vista. The 32-bit version is limited to 4GB RAM, while the 64-bit version allows 192GB, as well as added security and virtualization capabilities. While Microsoft is pushing 64-bit as a way to gain performance in the OS, it earlier this year advised users to install the 32-bit version of Office 2010, 'because currently many common add-ins for Office will not function in the 64-bit edition.'"

Preserving Virtual Worlds 122

The Opposable Thumbs blog has an interview with Jerome McDonough of the University of Illinois, who is involved with the Preserving Virtual Worlds project. The goal of the project is to recognize video games as cultural artifacts and to make sure they're accessible by future generations. Here McDonough talks about some of the technical difficulties in doing so: "Take, for example, Star Raiders on the Atari 2600. If you're going to preserve this, you've got a couple of problems. The first is that it is on a cartridge that is designed to work on a particular system that is no longer manufactured. And as long as you've got a hardware dependency there, you're really not going to be able to preserve this material very long. What we have been looking at is how feasible is it for things that fundamentally all have some level of hardware dependency there — even Doom has dependencies on DLLs with an operating system, and on particular chipsets and architectures for playing. How do you take that and turn it into something that isn't as dependent on a particular physical piece of hardware. And to do that, you need information about that platform. You need technical specifications that allow you to basically reproduce a virtualization that may enable you to run the software in its original form in the future. So what we're trying to do is preserve not only the games, but preserve the knowledge that you would need to create a virtualization platform to play the game."

New LLVM Debugger Subproject Already Faster Than GDB 174

kthreadd writes "The LLVM project is now working on a debugger called LLDB that's already faster than GDB and could be a possible alternative in the future for C, C++, and Objective-C developers. With the ongoing success of Clang and other LLVM subprojects, are the days of GNU as the mainstream free and open development toolchain passé?" LLVM stands for Low Level Virtual Machine; Wikipedia as usual has a good explanation of the parent project.

Work Underway To Return Xen Support To Fedora 13 93

Julie188 writes "Details on this are admittedly sketchy, but both Red Hat and Xen.org have gone on record promising that some kind of support for the Xen hypervisor is forthcoming for Fedora users. As we know, on Monday, Fedora 13 was released, chock full of features to appeal to business users. One of the ballyhooed improvements to 13 is virtualization — meaning KVM and only KVM — for Red Hat. Xen was dropped from Fedora a few releases ago and it hasn't come back in 13, except that 13 still supports Xen guests. Meanwhile, 'work is underway in Xen.org to add platform support to Fedora 13 post-release,' promises Xen.org's Ian Pratt."
