With Intel Corp. processors supporting the company's Virtualization Technology (VT) becoming more pervasive, Linux kernel developers are writing the code to improve hardware virtualization and hence performance. Speaking at this year's linux.conf.au Linux and open-source conference in Sydney, Intel software engineer Jeff Dike spoke about three virtualization methods -- User-Mode Linux (UML), Kernel Virtual Machine (KVM) and hardware virtualization.
FSMLabs says its real-time Linux distribution is being used to fly cameras above NFL games, film sets, and other events. RTLinux powers the real-time camera control software used by Cablecam, a provider of video footage to sports broadcasting companies and movie studios.

Nadia Derbey posted a set of patches to the Linux Kernel Mailing List titledAKT, Automatic Kernel Tunables, explaining,"this is a series of patches that introduces a feature that makes the kernel automatically change the tunables values as it sees resources running out." The kernel portion of the AKT framework is described as providing sysfs interfaces for registering tunables, and for activating the automatic tuning of registered tunables. Nadia explains the second feature,"it can be called during resource allocation to tune up, and during resource freeing to tune down the registered tunable." The userland portion of the framework provides an interface for configuring whether or not a tunable should be set automatically.The default automatic adjustment routine provided by the patches simply allow a tunable to be configured with a minimum and maximum values, as well as a thresholds.
SYDNEY -- One of the great things about Linux.conf.au is the chance to mingle with some of the brightest lights in the open source community. For example, Jeff Dike, author and maintainer of User-Mode Linux is here this week to talk about UML and the Kernel-based Virtual Machine (KVM). During one of the breaks on Monday, I sat down with Dike to talk about UML's immediate future, and picked his brain about other virtualization technologies.
Do we really need a separate distribution like GNewSense strictly for ideological purity? Ubuntu can be made truly free by removing the restricted modules package and leaving the multiverse packages disabled. That’s all you need to do. Not hard, is it? If Feisty Fawn, the next release, includes binary blobs in the kernel as Red Hat/Fedora does then there is exactly one extra step: recompile the kernel leaving out the offending bits. That’s the worst case scenario for ANY Linux distribution.
NEPOMUK is the social semantic desktop project which is planned to be integrated into KDE 4. The work is being done by Mandriva programmers Sebastian Trüg (of K3b's fame) and Stephane Lauriere. As the move to kdelibs is planned, there will be a couple of presentations in Paris to clarify the aims of the project and its technical aspects.
In the beginning of 2003, the Dutch government started a program called Open Standards and Open Source Software (OSSOS) to stimulate Dutch government agencies to use open standards in their software and to inform them about open source software. Last month, 10 big Dutch cities signed a Manifesto of the Open Cities, signaling that the OSOSS program is working.
Charles Wuischpard, an IBM veteran, has 'aggressive revenue goals' for the Linux computer maker.
Spanish software house Fluendo is selling codecs for Windows Media Player, MPEG-2 and MPEG-4 to Linux and Solaris users. Although there are open source media players that can work with Windows Media Player, the software can either fail to run or work only in a limited fashion, particularly on websites hosting video.
Kaffe using GNU Classpath (without AWT) is now working fine on SkyOS, just like Wine. Although there is no Wine graphics driver yet, you can already start Windows console applications directly from within SkyOS (once a Wine/SkyGI backend is available Wine should run on SkyOS as good as it does on Linux, and will be available via Software Store). On the driver side there is now an ACPI driver including support for ACPI power/sleep buttons (a SkyOS service, the PowerMonitor, will react on power events with configurable actions like shutdown, reboot, etc.). And finally, the SkyOS LiveCD is shaping together and should soon be available.
SYDNEY -- It took more than 17 hours in planes and a trip through customs, but I've made the trek from Denver, Colorado, to Sydney, Australia, for Linux.conf.au (LCA) 2007. Already it looks like the trip was worthwhile.
Samba software, is a free, open source implementation of networking protocols to share files between UNIX/Linux and Windows computers. There are many ways to set permissions to your Samba shares and improve security
. This article will cover some of the basic permissions and permission precedence with examples.

Text-editing operations are normally done interactively, inside a text editor application. Some tasks, however, can be accomplished quickly and easily, right from the UNIX command line. What's more, these one-liners can be used in scripts to automate various editing procedures.
Matt Asay has some good advice for folks asking him for career advice: "Work for an open source company." I'd wholeheartedly agree. I'd like to add "or within the open source group of a traditional software company".
Symbian Ltd will today announce the availability of libraries to support the Posix APIs, with a view to attracting developers of open source apps to port to its smart phone OS.
There is a growing recognition of Linux in the retail sector, as retailers are starting to see the advantages and cost savings of a Linux system, Columbitech said.

The Forum for Open Source Initiatives in India (FOSII) has been formed by a group of individuals from the Linux/Open Source to accelerate the adoption of Open Source by fostering innovation and development within the country. The FOSII is comprised of senior industry professionals, technology journalists, enthusiasts, mediapersons and others from the Open Source community. Sandeep Menon, convener of FOSII and director of Linux business for Novell West Asia, said, "FOSII members belong to various facets of the Linux/OSS (Open Source Software) ecosystem, which includes the industry, academia, government and the community.
Among other improvements, Libervis.com now has a link sharing section allowing FOSS and Free Culture people to share important "digital freedom" related links for each other.
This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast.
