David Airlie has re-based his drm-radeon-testing tree and there's now a whole lot of new code and features that users can play with and test. The drm-radeon-testing tree is a branch of the Linux kernel and is code for the Radeon DRM area that will ultimately make it into the mainline tree in the Linux 2.6.34 kernel series and later. To be found in drm-radeon-testing right now is new I2C code that supports the hardware I2C engines found on Radeon graphics cards and exposes it to user-space, a PLL algorithm rework, DRM power management support, basic Evergreen "R800" KMS support, and various other fixes and new additions. Like the recent R800 Evergreen in xf86-video-ati DDX support, the kernel mode-setting support lacks IRQ and any acceleration (2D, 3D, X-Video) support at this time for these Radeon HD 5000 series products...

As we alluded to last week, we have been in the process of benchmarking many Radeon HD 2000/3000/4000 series graphics cards using the open-source ATI Linux graphics stack with the Mesa R600/700 DRI driver. We have now carried out our first batch of R600/700 3D tests using this constantly evolving open-source driver to provide OpenGL acceleration and here are the results.

The past few weeks or so, there's been a lot of interest in a supposed battery status report bug in Windows 7. After installing Windows 7, some users reported seeing "consider replacing your battery"-warnings in systems that appeared to be operating just fine on Windows XP or Vista. After extensive research, Steven Sinofsky has now explained on the Engineering 7 blog that the fault is not with Windows 7 - it really, really is your battery.

"The 'Llano' processor that AMD described today in an ISSCC session is not a CPU, and it's not a GPU - instead, it's a hybrid design that the chipmaker is calling an 'application processor unit', or APU. Whatever you call it, it could well give Intel a run for its money in the laptop market, by combining a full DX11-compatible GPU with four out-of-order CPU cores on a single, 32nm processor die."

Google's Nexus One Android phone is selling at a much slower rate than the Droid, according to a research firm -- but happy customers include Linux creator Linus Torvalds, who endorsed the phone. Last week, meanwhile, the Torvalds-directed Kernel.org announced that Android code has been deleted from the Linux kernel....

Developed by industrial designer Barton Smith, the Stream Adaptive Computer System is an interesting take on making computing easier and more adaptable to suit the user's current needs. Today, he also unveiled the operating system and user interface that would run on Stream. It's... Amazing.

"The scuttlebutt is that IBM seemed perfectly content to wait until May to launch the Power7-based Power Systems servers, but something changed and compelled the company to move up the announcement of its first machines using the eight-core processor to today. Big Blue is not in a habit of explaining its motives or its timing for product launches, but it seems clear that IBM wanted to get out in front of a whole lot of processor and systems launches that are expected between now and the summer."

With state trackers emerging for the Gallium3D driver architecture to provide acceleration for a range of APIs from OpenGL ES and OpenVG to OpenGL and OpenCL, we knew it was likely that at some point there would be support for Microsoft's DirectX API. There was even a rumor of Tungsten Graphics already having a working DirectX state tracker...

You may remember that back in November last year, I wrote about the lack of a decent Pain.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.

There's plenty of ways to introduce subtle bugs into your code that give you a hard time finding and fixing. In this post I'd like to introduce you to malloc_debug, a heap implementation with added debug helpers, and outline how it can be used to find some of these problems.

Later this month, Microsoft will most likely unveil Windows Mobile 7 Windows Phone 7 at the Mobile World Congress. Rumours abound, and the latest set of rumours paint a rather dramatic turnaround for Microsoft's mobile platform - no more multitasking, application distribution limited to official channels, and a whole lot more.

Peter Hutterer has put out a new release candidate for X Server 1.7.5, which also marks this point release as being just about complete. There are still two weeks left before the 1.7.5 release is expected to be made and then after that we still may see X.Org Server 1.7.6...

"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."

Hey, that rhymes even! :P Lesson 4 is now out. Decision-making and repeating instructions are on the agenda for this one, expanding the repetoire of basic skills for writing code. Learning to Program With Haiku, Lesson 4.

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)

In a way, it's kind of sad. The old media squealing and squirming, trying pathetically to hold on to a time that has long been lost to the sands of... Well, time. Jeff Zucker, President and CEO of NBC, made such a pathetic attempt before a US Congress committee yesterday, claiming Boxee stole Hulu's content.

"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."

"The Mono Project releases the first preview of Moonlight 3.0, giving application developers a first look at the open-source implementation of Microsoft's Silverlight 3 technology for the Linux platform." Sadly, it's still Firefox-only.

ARM Holdings announced that more than 1.3 billion chips based on its designs were sold during the fourth quarter of 2009. Reporting better-than-expected financial results, the company added that it's signing up licensees for three new designs, code-named & Eagle,& & Heron,& and & Merlin.& ...

Intel has signed an agreement to acquire Virtutech, and Intel subsidiary Wind River will add the Virtutech product line, including its Simics virtualization and simulation software, to an embedded software product portfolio that already includes Wind River Linux. Intel's acquisition of Virtutech is expected to close this quarter, says Wind River....

We have just received official word from Unigine that they still are not ready to release their OpenGL Linux version of their Unigine Heaven benchmark. "Unfortunately we were asked by a hardware vendor not to release current version :(," said Denis Shergin, the Unigine Corp CEO...

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."

Sun Microsystems CEO Jonathan Schwartz, an advocate of Web 2.0, used Twitter early Thursday to announce his resignation. He was named CEO in 2006 as Sun faced a switch in strategic direction away from proprietary systems and toward open source code, including its valued Solaris 10 operating system. "Today's my last day at Sun. I'll miss it", he said in a tweet to his followers, reported the New York Times on its Web site at 1:12 a.m. Thursday. He added a bit of haiku: "Financial crisis, Stalled too many customers, CEO no more."

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.

"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."

While the Linux community is still waiting on the native Linux release of the OpenGL3-using Unigine Heaven tech demo with its heavenly graphics (it's being held off by a bugged ATI Catalyst driver), the core developers working on this advanced game engine continue adding in new features. One of the latest features added into this proprietary engine is physical destruction with a destructible body type currently offering three destruction patterns...

Last week we delivered our first Linux benchmarks of Intel's Core i3 Clarkdale processor with a variety of computational tests through the Phoronix Test Suite. While the Core i3 packs a nice performance punch, that is not all it has to offer. Also found on the Clarkdale (and mobile Arrandale) processors is an integrated 45nm graphics processor that is supposed to offer a decent level of performance in comparison to earlier Intel IGPs normally found on the motherboard's Chipset. In this article are these first Intel benchmarks for the Clarkdale graphics processor as we see how its open-source Intel driver stack compares to that of AMD with their open-source Radeon stack up through the Radeon R700 series.

As promised, Fusion Garage has sent out a press release regarding its Joo Joo tablet device. The news is all good: full production has started, and the device will ship this month, readily beating the iPad to market. It has also been confirmed it will come with Flash, and once Flash 10.1 goes final, the Joo Joo will be able to playback HD through Flash, so that things like Hulu will work.

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.
