benrothke writes "At first glance, The Art of the Data Center: A Look Inside the Worlds Most Innovative and Compelling Computing Environments appears like a standard coffee table book with some great visuals and photos of various data centers throughout the world. Once you get a few pages into the book, you see it is indeed not a light-read coffee table book, rather a insightful book where some of the brightest minds in the industry share their insights on data center design and construction."

First time accepted submitter xyourfacekillerx writes "After a long hiatus of developing (ASP.NET), I decided to pick it up again. I need to learn .NET and SQL for my new job (GIS tech using ESRI software). Down the road they need a PHP website, tons of automation tasks, some serious data consolidation, they want mobile apps in theory. This is not my job description, but I'm sure I can do it. Long story short, I need to setup a development environment on my home desktop, so I can do all this in my spare time. Trouble is, I share the machine (Win 8.1, 2.7 dual core pentium something or other, with virtualization support.) I want to avoid affecting the other users profiles. I currently use my profile for music production (Reason) and photography (Photoshop, et al) so it's already resource intensive with RAM, CPU and VMM. I'll be needing to install all of your basic Microsoft developer suites, IIS, SQl Server, ANdroid SDK, Java SDK, device emulators, etc. etc. Plus AMP and finally GIS software. There will obviously be a lot of services running, long build times, and so on. To wit, I wouldn't be able to use my desktop for my other purposes like the music editing. So I need some advice. Would it help to set up all these tools under a different account on the same Win 8.1 install? Or should I virtualize my development environment (and how?), and run the virtual machine side by side? Or should I add a HDD or secondary partition and boot to that when I intend to develop? I am poor ATM, but is there a cheap very mini PC I can place next to my desktop and run all my development software off that, remote desktop into it? I've done a lot of googling the last week and haven't turned up anything, so I turn to Slashdot. Please help me get organized so I can start coding again."
Nerval's Lobster writes "Will Xbox One and PS4 emulators hit your favorite download Websites within the next few years? Emulators have long been popular among gamers looking to relive the classic titles they enjoyed in their youth. Instead of playing Super Mario Bros. on a Nintendo console, one can go through the legally questionable yet widespread route of downloading a copy of the game and loading it with PC software that emulates the Nintendo Entertainment System. Emulation is typically limited to older games, as developing an emulator is hard work and must usually be run on hardware that's more powerful than the original console. Consoles from the NES and Super NES era have working emulators, as do newer systems such as Nintendo 64, GameCube and Wii, and the first two PlayStations. While emulator development hit a dead end with the Xbox 360 and PS3, that may change with the Xbox One and PS4, which developers are already exploring as fertile ground for emulation. The Xbox 360 and PS4 feature x86 chips, for starters, and hardware-assisted virtualization can help solve some acceleration issues. But several significant obstacles stand in the way of developers already taking a crack at it, including console builders' absolute refusal to see emulation as even remotely legal."
dcblogs writes "IDC expects that anywhere from 25% to 30% of all the servers shipped next year will be delivered to cloud services providers. In three years, 2017, nearly 45% of all the servers leaving manufacturers will be bought by cloud providers. The shift is slowing the purchase of server sales to enterprise IT. The increased use of SaaS is a major reason for the market shift, but so is virtualization to increase server capacity. Data center consolidations are eliminating servers as well, along with the purchase of denser servers capable of handling larger loads. The increased use of cloud-based providers is roiling the server market, and is expected to help send server revenue down 3.5% this year, according to IDC."
goodminton writes "I'm research the long-term consistency and reproducibility of math results in the cloud and have questions about floating point calculations. For example, say I create a virtual OS instance on a cloud provider (doesn't matter which one) and install Mathematica to run a precise calculation. Mathematica generates the result based on the combination of software version, operating system, hypervisor, firmware and hardware that are running at that time. In the cloud, hardware, firmware and hypervisors are invisible to the users but could still impact the implementation/operation of floating point math. Say I archive the virutal instance and in 5 or 10 years I fire it up on another cloud provider and run the same calculation. What's the likelihood that the results would be the same? What can be done to adjust for this? Currently, I know people who 'archive' hardware just for the purpose of ensuring reproducibility and I'm wondering how this tranlates to the world of cloud and virtualization across multiple hardware types."
mattydread23 writes "Amazon is getting into the desktop virtualization space. This is potentially huge news for providers like Citrix, but as writer Nancy Gohring points out, the company is starting small. Very small: 'The administrator console only allows managers to provision five WorkSpaces at a time. It's possible that will change when the service becomes generally available. For now, Amazon is accepting sign ups for a limited preview of the service. '"
An anonymous reader writes "I've recently been charged with updating our existing serial console access tools. We have 12 racks of servers each with a console server in it (OpenGear, ACS, and a few others). Several of these systems host virtual machines which are also configured to have 'serial' management (KVM, virt serial). In total it comes to about 600 'systems.' All the systems also have remote power management (various vendors). Right now our team has a set of home grown scripts and a cobbled together database for keeping this all together. Today any admin can simply ssh into the master, run 'manage hostname console' and automatically get a serial console or run 'manage hostname power off' to cut the power to a system. I'd rather use some tools with more of a community than just the 4 of us. What tool(s) should I move my group onto for remote serial/power management?"

MojoKid writes "Imagination Technologies has announced the first CPU based on its new version of the MIPS architecture. The new P5600 chip (codenamed Warrior) is a 32-bit CPU based on the MIPS Series 5 architecture and is designed to challenge companies like ARM in the embedded and mobile markets. Major features of the new chip include: support for 40-bit memory extensions, or up to 1TB of RAM, a 128-bit SIMD engine (Single Instruction, Multiple Data), and Hardware virtualization (MIPS R5 can virtualize other machines in hardware). The P5600 core is being touted as supporting up to six cores in a cache-coherent link, most likely similar to ARM's CCI-400. According to IT, the chip is capable of executing 3.5 DMIPs/MHz in CoreMark, which theoretically puts the P5600 on par with the Cortex-A15."
itwbennett writes "As part of the project to preserve the world's first website and all of the accompanying technology, CERN last week launched a line mode browser emulator. To make the browser experience authentic, the developers recreated how terminals would draw one character at a time by covering the page in black and then revealing each character by erasing a character-sized rectangle from that cover, one-by-one, line-by-line. They also recreated the sound of typing on older keyboards, specifically an IBM RS/6000 keyboard, by using HTML5 audio elements."
Nerval's Lobster writes "Linux vendors Red Hat and SUSE are pushing to make sure Linux-based virtual machines are an important part of datacenter-based hybrid clouds. The two are taking significantly different tacks toward the same destination, however. SUSE is using the visibility and cloud hype of VMware by extending its partnership with the virtualization provider to promote its SUSE Linux Enterprise Server for VMware as an alternative operating system for virtual machines running on VMware's vCloud Hybrid Service. Red Hat is happy to include VMware in its plans, but isn't limiting itself either to VMware-based clouds or, in fact, the idea that a Linux vendor has to tag along with a cloud- or virtualization developer to find its place in mixed infrastructures. 'We do not buy into the premise that a private or a hybrid platform based on one vendor's technologies and products is the answer,' wrote Bryan Che, general manager of Red Hat's Cloud Business Unit. More than 25 percent of customers want clouds or datacenter infrastructures using virtualization products from more than one vendor, according to a buyers' guide published in August by market researcher IDC."

Nerval's Lobster writes "Microsoft plans to raise the price of the Datacenter edition of the upcoming R2 release of Windows Server 2012 by 28 percent, adding to what analysts call a record number of price increases for enterprise software products from Redmond. According to licensing data sheets available for download from the Windows Server 2012 R2 Website (PDF), the price of a single license of Windows Server 2012 R2 Datacenter will be $6,155, compared to $4,809 today—plus the cost of a Client Access Licenses for every user or device connecting to the server. News of the increase was posted yesterday by datacenter virtualization and security specialist Aidan Finn, a six-time Microsoft MVP who works for Dublin-based value added reseller MicroWarehouse Ltd. and has done work for clients including Amdahl, Fujitsu and Barclays. The increase caps off a year filled with a record number of price increases for Microsoft enterprise software, according to a Tweet yesterday from Microsoft software licensing analyst Paul DeGroot of Pica Communications."

Dan Kusnetzky and I started out talking about cloud computing; what it is and isn't, how "cloud" is often more of a marketing term than a technical one, and then gradually drifted to the topic of how IT managers, CIOs, and their various bosses make decisions and how those decisions are not necessarily rational. What you have here is an 18-minute seminar about IT decision-making featuring one of the world's most experienced IT industry analysts, who also writes a blog, Virtually Speaking, for ZDnet.
Nerval's Lobster writes "The same layers of virtualization that have made networked business computing so much more convenient and useful have also given bad guys much easier access to both physical and virtual servers within previously-secure datacenters. A group of engineering researchers from MIT has demonstrated one approach to making secure servers harder to access using a physical system that prevents attackers from reading a server's memory-access patterns to figure out where and how data are stored. Ascend, which the group demonstrated at a meeting of the International Symposium on Computer Architecture in Tel Aviv in June (PDF), is designed to obscure both memory-access patterns and the length of time specific computations take to keep attackers from learning enough to compromise the server. The approach goes beyond simply encrypting everything on the whole server to try to shut off one of the most direct ways attackers can address the server directly — whether the server is an air-gapped high-security machine sitting in an alarmed and guarded room at the NSA or a departmental server whose security settings are a little too loose. Other ways to try to obscure memory-access patterns were built as applications to run on the server. Ascend is the first time a hardware-only approach has been proposed, and the first to approach an acceptable level of performance, according to Srini Devadas, Edwin Sibley Webster Professor of Electrical Engineering and Computer Science, the MIT researcher who oversaw the team developing the hardware."
First time accepted submitter Jagungal writes "Although the core Xen hypervisor has always been open source from the start, Citrix have now released the next version of their XenServer including all features and tools under an open source license. This includes also introducing a new XenServer.org community portal. The major change for users is that they now get all features from the licensed version for free but unless they pay for support, they have to do all security updates manually. Change logs for the new version 6.2 can be found here. It's been a few years since Citrix started giving it away, free as in beer.
