The Linux community is splitting - right down the middle, at this point - over Microsoft's controversial claims that the open-source operating system infringes on patents it holds. Last Tuesday, Mandriva became the third Linux vendor within five days to say it isn't interested in signing a licensing deal with Microsoft to avoid possible infringement claims. A blog posting to that effect by Mandriva CEO Francois Bancilhon followed similar declarations by officials at Red Hat and Canonical.

"Let's face it; some distributions have better controls for handling display issues than others. Two that do it right out of the box that come to mind include Fedora (Red Hat) and openSUSE (Novell). Each includes tools that minimize the need to do what I gleefully refer to as the 'Xorg dance'. Basically, these options mean you are going to be spending more time exploring what these distros have to offer, yet less time wondering why your resolution looks completely off. Unfortunately, even with the latest release of Ubuntu, we have yet to see this level of functionality."

Alan Cox talks about cooperation with hardware vendors, patent law, microkernels, and GPLv3: "I think is a bad idea and that Novell are going to get stung by the GPLv3, and rightfully so. The license is designed to keep the software free, if it fails to do this then it needs fixing, so GPLv3 hopefully will fix this flaw."

"The Linux kernel is the core of a large and complex operating system, and while it's huge, it is well organized in terms of subsystems and layers. In this article, you explore the general structure of the Linux kernel and get to know its major subsystems and core interfaces."

The T2 SDE release 7.0-rc named 'Water Falls' features two newly supported CPU architectures AVR32 and Blackfin as well as the brand new GCC 4.2 and GlibC 2.6. Additionally the T2 7.0 series comes with over 400 new packages while most of the existing packages received an update, including KDE 3.5.7, GNOME 2.18.2, X.org 7.3, XFCE 4.4.1, and Enlightenment 17. Many new features were implemented, including architecture and target package overlays.

At its 10th anniversary and after a period of uncertainty for the RPM community, together with a new roadmap towards version 5.0 the project environment of the popular Unix software packaging tool RPM Package Manager was relaunched under the domain rpm5.org by the newly formed RPM project team, further on lead by RPM's primary developer Jeff Johnson. The primary goals of RPM 5.0 are the additional support for the XML based archiving format XAR, an integrated package dependency resolver, further improved portability and extended cross-platform support. Note: Please note that rpm5 is a fork of the 'real' rpm project.

"The one 'hole' in my workflow has been OCR. For years, people have been able to scan a document and have it converted into real text. One of my old printers even came with OCR software included - for Windows of course. But when I've really needed OCR, I've just assumed that there were no high quality packages available for Linux. Recently I decided to find out for myself (a complete OCR virgin) what is available, how to use it, and what the results are like. I installed every free OCR package I could find, and systematically tested them. They all work very differently, so I tried to design a simple test for my specific needs."

"PCLinuxOS is a live CD distribution that enables users to test Linux without actually having to install it. The highly anticipated new version, PCLinuxOS 2007, was released on Monday. Its intuitive selection of software, high level of stability and functionality, and the quality of the graphics make this the distribution's best release ever."

"Good operating system performance depends in part on the operating system's ability to efficiently manage resources. In the old days, heap memory managers were the norm, but performance suffered due to fragmentation and the need for memory reclamation. Today, the Linux kernel uses a method that originated in Solaris but has been used in embedded systems for quite some time, allocating memory as objects based on their size. This article explores the ideas behind the slab allocator and examines its interfaces and their use."

Linus Torvalds has announced the first release candidate for version 2.6.22 of the Linux kernel, noting that the changelog itself for this release is just too big to put on the mailing list. According to the kernel-meister himself: "The diffstat and shortlogs are way too big to fit under the kernel mailing list limits, and the changes are all over the place. Almost seven thousand files changed, and that's not double-counting the files that got moved around. Architecture updates, drivers, filesystems, networking, security, build scripts, reorganizations, cleanups... You name it, it's there."

"Arch Linux, or Arch for short, is one of the uprising new distributions. Well, at least compared to old folks like Debian or Slackware it’s still fresh and shining. Arch is gaining new users and good reviews every day. Let’s find out why this is happening." More here.

"Wireless networking on Linux is entering a new era. An era of bliss and ease; where users and network administrators have abundant time for relaxing lie-abouts on sunny warm hills because their wireless systems are humming along contentedly, instead of being vexing and unreliable. OK, so maybe it's not going to be quite that Utopian, but things are definitely looking up, thanks to a lot of hard work by a lot of talented developers. So what's going to be different? A brand-new wireless LAN kernel stack, which is going to reduce the current WLAN herd-of-cats approach to a single unified subsystem that supports all wireless drivers."

According to kerneltrap: "The future of Reiser4 was raised on the lkml, with the filesystem's creator, Hans Reiser, awaiting his May 7th trial. Concerns that the filesystem wasn't being maintained were laid to rest when Andrew Morton stated, 'the namesys engineers continue to maintain reiser4 and I continue to receive patches for it.'"

Linux Kernel 2.6.21 has been announced. Linus writes: "So the big change during 2.6.21 is all the timer changes to support a tickless system (and even with ticks, more varied time sources). Thanks (when it no longer broke for lots of people ;) go to Thomas Gleixner and Ingo Molnar and a cadre of testers and coders." More info here and here.
