While some potential users of the iPad may be put off by such things as its lack of multi-tasking, which they might have expected on a device this size, the device may prove highly useful to users with varying disabilities. Ms Ricky Buchanan runs the ATMac website, which is dedicated to accessibility issues with Apple products.

"Whereas the iPhone is aimed at short, focused tasks, the iPad is more likely to lend itself to longer, more general tasks that involve using multiple apps, just as we're used to on the Mac. It's easy to imagine wanting to use an iPad to read text in Mobile Safari, copy some text to a Pages document, and send that document to a colleague via Mail. That specific example may turn out to be possible with the current iPhone OS, but it points toward needing more ways for iPad apps to work together in the future."

Notebooks with dual GPUs have been shipping for a while now, but switching between the fancy discrete GPU and the low-power integrated one hasn't exactly been painless. Today, NVIDIA introduced a technology called Optimus, which makes the switching process automatic and transparent. In Windows, that is.

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.

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."

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."
