We've been working on an "OSNews version 5" upgrade for several months, and with several months to go, we decided to make some incremental changes to OSNews on the existing codebase. The major change, as you probably already noticed, is that we've removed the "Page1/Page2" tabs and instead have OSNews stories with original content and commentary in one column, and news, items on OS-related topics gleaned from other sources in the other. Read on for more details on the changes we've implemented.

You may remember that back in November last year, I wrote about the lack of a decent Paint.NET-like application for Linux (or, more specifically, for Gtk+ distributions, since Qt has Krita). As it turns out, this compelled Novell employee Jonathan Pobst to code a Paint.NET clone in Gtk+ using Cairo. Version 0.1 is here, and it's remarkably advanced for something so young.

"The ancient bug was discovered by Google security researcher Tavis Ormandy in January 2010 and involves a utility that allows newer versions of Windows to run very old programs. Mr Ormandy has found a way to exploit this utility in Windows XP, Windows Server 2003 and 2008 as well as Windows Vista and Windows 7. The patch for this vulnerability will appear in the February security update. Five of the vulnerabilities being patched at the same time allow attackers to effectively hijack a Windows PC and run their own programs on it."

A quick round up of various web-related news items. First up, a new open source product entitled the "Highgate media suite" will bring OGG video decoding to Silverlight. Microsoft have just joined the SVG working group (arguably 10 years late, but it's better than nothing). Adobe promise significant improvements in Flash 10.1, including Core Animation rendering on OS X and lowered CPU usage. Finally, CoperLicht--a WebGL JavaScript 3D engine (Quake in JS will be here one day)

"Today, Clang completed its first complete self-host! We built all of LLVM and Clang with Clang (over 550k lines of C++ code). The resulting binaries passed all of Clang and LLVM's regression test suites, and the Clang-built Clang could then build all of LLVM and Clang again. The third-stage Clang was also fully-functional, completing the bootstrap."

With all the virtualization schemes running on top of Linux, how do they exploit the underlying kernel for I/O virtualization? The answer is virtio, which provides an efficient abstraction for hypervisors and a common set of I/O virtualization drivers. Discover virtio, and learn why Linux will soon be the hypervisor of choice.

Finally something we can work with. While both the iPad and the Joo Joo are technically still vapourware, people have at least had the opportunity to play with the former, while the latter remained somewhat illusive. Now that the device has been set to ship at the end of this month, Ars Technica finally had some time to play with the Joo Joo and talk to Fusion Garage's CEO, Chandra Rathakrishnan. There's good news, and there's (potentially) bad news.

"In a definitive defeat for film studios - and in a first case of its kind worldwide - Australia's Federal Court has ruled that ISPs have no obligation to act on copyright infringement notices or to disconnect subscribers after receiving multiple letters. If copyright holders want justice for illegal file-sharing, they need to start by targeting the right people: those who committed the infringement."

Now this is something you don't read every day. Dick Brass, vice president at Microsoft from 1997 to 2004, has written an article for The New York Times' Op-Ed section, detailing the flaws in Microsoft's corporate culture, and how they've severely affected the company in a negative way. Telling, and painful. And, in a way, very sad. Update: Microsoft responds. "For Microsoft, it is not sufficient to simply have a good idea, or a great idea, or even a cool idea. We measure our work by its broad impact."

"The venerable GNU Image Manipulation Program is undergoing a significant transformation. The next major release, version 2.8, will introduce an improved user interface with an optional single-window mode. Although this update is still under heavy development, users can get an early look by compiling the latest source code of the development version from the GIMP's version control repository."

Symbian has completed the process of open sourcing its entire code base, in advance of its June deadline. While the release is ahead of schedule, the first phones - expected to be out early next year - will hit the market more than two years after the first Android phone became available. The code is expected to become available on the Symbian developer page on Thursday.

We've got news from the MPEG-LA, regarding any possible H264 license changes they might institute at the end of this year. More specifically, they've put out a press release stating that they will not change one specific aspect of the license that governs the AVC Patent Portfolio (to which h264 belongs): MPEG-LA will not collect royalties for internet video that is free to end users. The press release is highly confusing, so let's de-construct what's going on here.

Ah, the ARM chip. ARM is a hugely successful architecture, and can be found in just about every cell phone or other small device out there. ARM, however, wants more, and for a long time now we've been hearing predictions about an upcoming massive rise in ARM netbooks - so far, this hasn't materialised. Warren East, ARM's CEO, said in an interview with PC Pro that netbooks could one day make up 90% of the laptop market - preferably powered by ARM processors of course.

"The notion of a Firefox smartphone browser seemed implausible only a few short years ago, but today it's very much a reality. Firefox Mobile for Maemo demonstrates the flexibility of the Firefox Web browser and its potential to bring a desktop-like browsing experience to constrained computing environments. It is truly an impressive achievement, but it's only the beginning of what Mozilla hopes to accomplish on handheld devices. Stay tuned for our follow-up about Weave, in which we will examine some of the opportunities for innovation created by Firefox Mobile."
