Xen 3.3 is available from the Ubuntu 8.10 repositories, but the Ubuntu 8.10 kernels (2.6.27-x) are domU kernels, i.e., they work for Xen guests (domU), but not for the host (dom0). Therefore we need to build our own dom0 kernel. This guide explains how to do this with a 2.6.27 kernel.

Even before the proverbial ink was dry on last week's interoperability deal between Microsoft and Red Hat, Linux competitor Novell laid off a still unknown number of employees involved with the open source openSUSE community.

Yes ladies and gentlemen, it's official... Ubuntu 9.04 has a whole new notification system, almost the same as the one in the Macintosh operating system.

VectorLinux made their 6.0 final release over the weekend. The first thing that is noteworthy about this release is that they have developed their own GUI installer, and it is quite nice.

As of late, file-systems have been a popular topic among Linux developers and users. The EXT4 file-system was recently stabilized and it brings some modest performance improvements and is finding its way into modern distributions. While not yet stabilized, the Btrfs file-system was merged into the Linux 2.6.29 kernel and is poised as the Linux competitor to Sun's famed ZFS file-system. There is also open-source work underway in supporting Microsoft's exFAT file-system on Linux. On top of all of that, there is also the Tux3 file-system.

Learn how you can improve UNIX file system performance and security. The UNIX® operating system enables you to split up your disk data into multiple volumes. Knowing how to do this is only half the battle, though; to make effective use of this ability, you must understand how the files on a UNIX system are organized as well as why they're organized in this way.

Linux MCE is superior to windows MCE * Cost The number one reason for choosing Linux, people have reported building a Linux media center with $400 total cost. Top that!

I have something of a relationship with both Python and Django, the latter because I use Django more or less regularly to contribute my portion of an application (which shall remain nameless for the moment) that my company ("my" in the sense that I work there, not that I actually own anything) is developing. I'm already sold on the relative simplicity and power of Python based on my attempts to hammer away with the language, so this book, at least as far as the topic is concerned, is everything I could ask for. But can the same be said for the content of the book?

KDE 4.1, launched at the end of July 2008, became the first release we could heartily recommend as a replacement for the ageing 3.5, and a solid nine months of updates to 4.1 has created a stable and innovative environment that can only get stronger as 4.2 beds itself into 2009. But KDE is still KDE, and that means that many of its best features are undocumented and undisclosed. Which is why now is the best possible time for a feature crammed full of the best tricks we can find for getting the most out of KDE 4. It doesn't matter if you're a new convert, an experienced user, or a potential switcher, you'll find something in the following pages that will make you feel a micron of pride of what open source can achieve.

Almost two years after Etch, Debian is putting the much-anticipated Lenny release on the proverbial shelves. There are some pretty nice new features in this release. In this article, we’re going to cover installation, basic setup, disk encryption, and try out some of Lenny’s new moves.

The relationship between embedded system developers and the kernel community is known for being rough, at best. Kernel developers complain about low-quality work and a lack of contributions from the embedded side; the embedded developers, when they say anything at all, express frustrations that the kernel development process does not really keep their needs in mind. A current discussion involving developers from the Android project gives some insight into where this disconnect comes from.
