Hand-held devices could soon have pressure-sensitive touch-screens and keys, thanks to a UK firm's material that exploits a quantum physics trick. The technology allows, for example, scrolling down a long list or webpage faster as more pressure is applied. A division of Samsung that distributes mobile phone components to several handset manufacturers has now licensed the "Quantum Tunnelling Composite". The approach could find use in devices from phones to games to GPS handsets.

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.

And there we are, the KDE team has released KDE Software Compilation 4.4, formerly known as, well, KDE. Major new features include social networking and online collaboration integration, the new netbook interface, the KAuth authentication framework, and a lot more.

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 '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."

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.

Mozilla has announced that they are going to drop support for Mac OS X 10.4 Tiger definitively. "Mac OS X 10.4 was released in April of 2005 and a lot has changed since then," Josh Aas writes, "We would like to take advantage of more modern technologies on Mac OS X and 10.4 support has been a hindrance. Where we can work around supporting 10.4, doing so consumes valuable time and effort. Neither Chrome nor Safari has to deal with this."

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.

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.

"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."

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.

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.
