Windows 8 sales are good, if not great, at 40 million copies in the first month

Tami Reller, corporate vice president (and chief financial officer and chief marketing officer) for Windows and Windows Live, announced today that Microsoft has sold 40 million Windows 8 licenses after its first month of retail availability. Is that number good, bad, or merely mediocre? Probably good, but perhaps not great. Microsoft sold 60 million copies of Windows 7 in the first ten weeks of that operating system’s availability, with the Wall Street Journal estimating that 40 million copies were sold in the first month. With Windows 8 selling 40 million copies in five weeks, it seems to be selling at about the same pace as Windows 7. Considering the different market dynamics—Windows 7 was an iterative release that fulfilled substantial pent-up demand as businesses chose to ignore Windows Vista whereas Windows 8 is a more controversial update being brought to a market that is generally happy with Windows 7 anyway—this is a healthy performance. Windows 7 sold very well and matching it is no mean feat. The apparent failure to surpass Windows 7’s launch could explain the mixed reports on early sales. Strong sales can still be disappointing if they were expected to be stronger still. Read 4 remaining paragraphs | Comments

Amazon floats Windows Server 2012 into AWS cloud

Amazon Web Services announced today that it will now offer virtual Windows 2012 server instances as part of its Enterprise Compute Cloud (EC2) service. Amazon Web Services’ Windows team General Manager Tom Rizzo—who until this June was Microsoft’s Senior Director for the Office and Office 365 teams, and had previously run Microsoft’s SharePoint team—revealed the addition of the Server 2012 platform in a post on the AWS team’s official blog . As Ars found in our review of Windows Server 2012 , the operating system has a number of advantages for cloud users over previous Windows Server operating systems, including better software-defined networking and improved remote configuration through PowerShell commands. Amazon is hardly the first to offer Server 2012 as a public cloud service—Microsoft’s Azure and a number of smaller cloud providers have had Server 2012 instances available since the operating system was released (and in some cases, before that). But there are a number of things that Amazon has done with Windows 2012 that are sure to draw attention from companies and developers looking to ease into using Server 2012 or go big right away. One is Amazon’s support for Server 2012 in AWS’s Elastic Beanstalk , a service that automatically takes care of many of the deployment and capacity-provisioning aspects of deploying an application to the AWS cloud. Amazon is also offering Server 2012 as part of its “free” tier of services as well—up to 750 hours of EC2 “Micro Instance” compute time per month, for up to a year. There’s also direct integration into Microsoft Visual Studio 2012 through the AWS Explorer Read 1 remaining paragraphs | Comments

Researcher advises against use of Sophos antivirus on critical systems

Antivirus provider Sophos has fixed a variety of dangerous defects in its products that were discovered by a security researcher who is recommending many customers reconsider their decision to rely on the company. “Sophos claim that their products are deployed throughout healthcare, government, finance, and even the military,” Tavis Ormandy wrote in an e-mail posted to a public security forum . “The chaos a motivated attacker could cause to these systems is a realistic global threat. For this reason, Sophos products should only ever be considered for low-value non-critical systems and never deployed on networks or environments where a complete compromise by adversaries would be inconvenient.” A more detailed report that accompanied Ormandy’s e-mail outlined a series of vulnerabilities that attackers can exploit remotely to gain complete control over computers running unpatched versions of the Sophos software. At least one of them requires no interaction on the part of a victim, opening the possibility of self-replicating attacks, as compromised machines in turn exploit other machines, he said. The researcher provided what he said was a working exploit against Sophos version 8.0.6 running Apple’s OS X. Attackers could “easily” rewrite the code to work against unpatched Sophos products that run on the Windows or Linux operating systems, he said. Read 7 remaining paragraphs | Comments

Better on the inside: under the hood of Windows 8

Windows 8’s most obvious—and most divisive—new feature is its user interface . However, it would be a mistake to think that the user interface is the only thing that’s new in Windows 8: there’s a lot that’s changed behind the scenes, too. Just as is the case with the user interface, many of the improvements made to the Windows 8 core are motivated by Microsoft’s desire to transform Windows into an effective tablet operating system. Even those of us with no interest at all in tablets can stand to take advantage of these changes, however. For example, Windows 8 is more power efficient and uses less memory than Windows 7; while such work is critical to getting the software to run well on low-memory tablets with all-day battery life, it’s equally advantageous for laptop users. The biggest single piece of technology that is new to Windows 8 is, however, squarely Metro focused: it’s a large set of libraries and components called WinRT. I’ve already written extensively about what WinRT is, so I won’t be getting into that here, but there are system capabilities that WinRT apps can use (or are forced to use) that are interesting in their own right.

Storage Spaces explained: a great feature, when it works

Windows Home Server was never a particularly popular product, but it did bring some interesting features to the table for the few who used it and became fans. One of these features was called Drive Extender, and its claim to fame was that it allowed users to pool their system’s hard drives so that they were seen by the operating system as one large hard drive. This obviated the need to keep track of the amount of free space across several disks, and it also allowed users to automatically mirror their data to multiple disks at once, keeping their files safe in the event of drive failure. Microsoft killed Drive Extender not long before pulling the plug on the Windows Home Server entirely , but the intent behind it lives on in Windows 8’s new Storage Spaces feature: “Storage Spaces is not intended to be a feature-by-feature replacement for that specialized solution,” wrote Microsoft’s Rajeev Nagar in a blog post introducing the feature, “but it does deliver on many of its core requirements.” In essence, Storage Spaces takes most of Drive Extender’s underlying functionality and implements it in a way that is more technically sound; early versions of Drive Extender sometimes corrupted data when copying files between drives and mangled file metadata, but the underlying filesystem improvements made to support Storage Spaces should make it much more robust, at least in theory.

$99 Raspberry Pi-sized “supercomputer” hits Kickstarter goal

A prototype of Parallella. The final version will be the size of a credit card. Adapteva A month ago, we told you about a chipmaker called Adapteva that turned to Kickstarter in a bid to build a new platform that would be the size of a Raspberry Pi and an alternative to expensive parallel computing platforms. Adapteva needed at least $750,000 to build what it is calling “Parallella”—and it has hit the goal. Today is the Kickstarter deadline, and the project is up to more than $830,000 with a few hours to go. ( UPDATE : The fundraiser hit $898,921 when time expired.) As a result, Adapteva will build 16-core boards capable of 26 gigaflops performance, costing $99 each. The board uses RISC cores capable of speeds of 1GHz each. There is also a dual-core ARM A9-based system-on-chip, with the 16-core RISC chips acting as a coprocessor to speed up tasks. Adapteva is well short of its stretch goal of $3 million, which would have resulted in a 64-core board hitting 90 gigaflops, and built using a more expensive 28-nanometer process rather than the 65-nanometer process used for the base model. The 64-core board would have cost $199. Read 2 remaining paragraphs | Comments
