Both IDC and Gartner have released their preliminary figures on the state of the US and worldwide PC market, and while both companies agree that overall, the market declined about 3-5% worldwide, they differ when it comes to the figures of Apple. Quite interesting.

Mono from SVN is now able to use LLVM as a backend for code generation in addition to Mono's built-in JIT compiler. "This allows Mono to benefit from all of the compiler optimizations done in LLVM. For example the SciMark score goes from 482 to 610. This extra performance comes at a cost: it consumes more time and more memory to JIT compile using LLVM than using Mono's built-in JIT, so it is not a solution for everyone. Long running desktop applications like Banshee and Gnome-Do want to keep memory usage low and also would most likely not benefit from better code generation. Our own tests show that ASP.NET applications do not seem to benefit very much (but web apps are inherently IO-bound). But computationally intensive applications will definitely benefit from this. Financial and scientific users will surely appreciate this performance boost."

"Is password protection an inherently flawed security model? A hack into a Twitter employee's Gmail provided access to a number of confidential Twitter docs housed in Google's cloud. What does that say about cloud security? Information from the docs was leaked to the media and published on various outlets." This may be a hard blow to those who have hopes in tossing sensitive data into the cloud.

The uphill battle that open-source programs face to steal ground from proprietary software comes with added pitfalls in China, where problems like software piracy take away strengths that open source has elsewhere. The Chinese government backs multiple domestic open-source projects, but their software is not widely used. Low awareness, a lack of big open-source projects and difficulty finding expertise in certain programming languages all hamper the development of open source in China.

One of the more controversial features of Google's Chrome/Chromium web browser is the way it handles updates. Contrary to other browsers, updates on Chrome are installed silently and automatically, without asking for the user's consent. While convenient and effective, it was also a security risk and sometimes it slowed people's machines down. Google now proposes a fix called Courgette.

For a while now, the Palm Pre and its webOS have been out and about, but the accompanying App Catalog remained remarkably empty, because Palm had not yet opened its software development kit for everyone. The SKD was leaked not too long ago, and today Palm has announced the official release of the Mojo SDK for everyone who wants to get their hands on it. It includes a webOS emulator.

It's time for another "OSNews asks" item. This time, I want to focus on something that I've been wanting to talk about with you all before, but never found the time for. The question is simple: which feature(s) from other operating systems would you like to see in your own main operating system?

Jeff Layton talks to Valerie Aurora, file system developer and open source evangelist, about a wide range of subjects including her background in file systems, ChunkFS, the Union file system and how the developer ecosystem can chip in.

One of the problem with operating system updates is that you often need to reboot the system. While this is nothing but a minor nuisance for us desktop users, it's a bigger problem when it comes to servers. Ksplice is a technology that allows Linux kernel patches to be applied without actually restarting the kernel.

"The latest version of Microsoft's flagship operating system, Windows 7, is available for pre-order in the UK. Amazon said that sales of Windows 7 in the first eight hours it was available outstripped those of Windows Vista's entire 17 week pre-order period."

"Microsoft has announced pricing for Azure that marginally undercuts Amazon on raw computing for Windows-based clouds but remains more expensive than the mega book warehouse's Linux option. The company has said it will charge $0.12 per compute hour for its Windows Azure Compute. Amazon's price for an ondemand Windows instance starts at $0.125. Amazon's Linux-based service undercuts Windows, with pricing starting at $0.10 per computing hour. Add in storage, and Azure's price will creep up further against Amazon: Azure will charge $0.15 per gigabyte stored versus $0.10 per gigabyte each month from Amazon."

During his keynote speech at the Worldwide Partner Conference, Steve Ballmer has dismissed Google's announcement of Chrome OS. "There's good data that says 50 percent of the time that someone's on their PC, they're not doing something with the Web browser," Ballmer said, suggesting that an ideal operating system would provide both rich online and offline integration. It is not sure yet what Chrome OS will exactly offer.

Microsoft plans to use Windows Embedded to combat rival operating systems in smartbooks and a number of other devices meant to always be connected to the Internet that Microsoft calls CIDs, or consumer Internet devices. In this interview Kevin Dallas, the general manager of Microsoft's Windows Embedded business, discussed Microsoft's strategies for smartbooks and other devices, such as the company's Haiku concept device.

YouTube will be phasing out support for Internet Explorer version 6. "Judging by this screenshot taken by an IE6 user who was watching some videos on YouTube, it appears the Google company will be phasing out support for the browser shortly."
