Xandros has announced the end of Linspire. The company says that it had too many for-pay distributions running around in the company portfolio, so one was bound to be cut. Linspire didn't make it. "Xandros purchased Linspire, the company, earlier this summer. This week, the company announced that it was going to revamp community distribution Freespire, basing its next version on Debian instead of Ubuntu, and using it as a precursor for Xandros Desktop Professional, in much the same way Red Hat uses Fedora and SUSE uses openSUSE. But the company didn't need multiple for-pay desktop distributions, so Linspire is getting the boot."

Here is an interesting discussion of the changes KDE 4.x (via Mandriva Linux 2009 pre-releases) brings to desktop interaction. The article argues that KDE 4 might very well be the next big thing in computing, as it finally tries to steer away from the Xerox desktop metaphor we've all been using since the glory days of disco. While I personally don't really believe KDE 4.x to be revolutionary (I see it more as evolution with pepper in its butt), the article details many of the new things in KDE 4.x, and might make the lives of those first confronted with the new desktop just that little bit easier.

Ars Technica has analyzed recently publicized Vista's security flaws. "Unfortunate, yes, but not as was reported in the immediate aftermath of the presentation evidence that Vista's security is useless, nor does this work constitute a major security issue. And it's not game over, either. Sensationalism sells, and there's no news like bad news, but sometimes particularly when covering security issues, it would be nice to see accuracy and level-headedness instead. ... Furthermore, these attacks are specifically on the buffer overflow protections; they do not circumvent the IE Protected Mode sandbox, nor Vista's (in)famous UAC restrictions."

For a technology that has been in stable release since May 22, 2000, PHP 4 has finally reached the end of its official life. With the release of PHP 4.4.9, official support has ended and the final security patch for the platform issued. With PHP 5 offering a viable upgrade path for the last few years, the recommendation is for addministrators and developers is to move to the PHP 5 platform (if they haven't already done so), which is currently at 5.2.6. For those who are not able to migrate their systems to the new version of PHP noted PHP security expert, Stefan Esser, will continue to provide third party security patching for the PHP 4 line through his Suhosin product.

ACM has announced the availability of the SIGOPS Operating Systems Review, an Issue on Research and Developments in the Linux Kernel. It is available, for free, from the ACM Archives site. The issue has 12 papers about the advances that have been merged or are candidates to be merged into the Linux kernel, as well as new idea papers discussing promising experimental work.

When the story about Microsoft shelling out $100,000 to Apache for ASF sponsorship broke across my radar it rather tickled my funny bone and my curiosity. When ASF Chairman Jim Jagielski declared that "Microsoft's sponsorship makes it clear that Microsoft 'gets it' regarding the ASF" I had a fit of the giggles and then, like many others, I started to ponder on the reasons why and what it actually meant. Gary Richmond explores Microsoft's motives. You can read the full article at Freesoftware Magazine

The Genode OS framework, the reference implementation of the Genode operating system architecture, has seen its first release. "Genode is a novel operating-system architecture that enables dynamic workload while retaining security and robustness. The fundamental difference of Genode compared to other OS architectures is its strict organizational structure, which allows the execution of sensitive applications with a trusted computing base of a few thousand lines of code beside high-complexity workload. With its organizational approach, the architecture facilitates a clean separation of policies and mechanisms, and enables the definition and application of system policies in a natural and distributed fashion." The Genode OS Framework runs on Linux via libSDL, or on real hardware on top of the L4/Fiasco microkernel.

The JNode team has released the latest version of their operating system written in Java (it does have a small assembler nano kernel). "This release features the integration of the OpenJDK implementation of Swing and AWT, and significant improvements to the overall JNode GUI including improved painting and font rendering, generic VESA support and graphical console. The release also includes a new command argument framework for the shell, reworked shell commands, a configure tool for the JNode build environment, Samba file system with read/write support and many stability and bug fixes across the whole system." They have screenshots, a changelog, and (surprise!) a download page.

From OpenSuse's automatic green-finding algorithm, to Fedora's long-winded concept explanations, examining each distribution's art process can tell you a lot about the distribution.

"The Linux Foundation has just released a beta of a new program, Linux Application Checker (AppChecker), that's going to make independent software vendors and other programmers start to love developing for Linux." This program checks your application against different versions of the Linux Standard Base (LSB), and against all the Linux distributions in the LSB Database. After the test is done it will present a report about the compatibility status of your application with the various distributions, and which external libraries and interfaces your application uses.

It seems Lenovo is being selective in which markets get Linux on its new range of IdeaPad netbooks. "People in most markets Lenovo serves, including Singapore, China and the UK, will be offered the company's new IdeaPad S10 with either Microsoft Windows XP or a Linux OS, but Australian and US computer buyers will only be offered Windows XP according to Lenovo."

"In a little over a month since version 0.3.5, we are announcing the release ReactOS 0.3.6. This release along with the rest of the 0.3.x series is still considered alpha quality software, so do not set your expectations too high. ReactOS 0.3.6 is the product of the current development focus: bugfixes, compatibility, and stability."

The Mozilla and Nokia teams have been working hard to port Firefox 3 and the Mozilla Platform to Qt and there are now some solid results available from their efforts. An experimental build of Firefox Qt is available and you can download the sources from Mozilla's mercurial repository. The plan is to merge the Qt branch into the central Mozilla branch to make the port official.

IBM has marked its 10 years of participation in Linux and open source with an open source code contribution focused on supercomputing.
