Xen is a powerful new virtualization system that enables you to run multiple operating systems on one computer. Here's how you can install it on your Fedora machine, and how to get it configured to best suit your environment. This article is excerpted from the book Fedora 7 Unleashed by Andrew Hudson and Paul Hudson, SAMS Publishing, August 2007.

Can artists get away with using a PC over a Mac? When considering the fact that many art students are likely to be working inside of Mac labs at their respective schools, it does tend to make sense to follow the flow of things and use a Mac at home as well.

In early August I stated in this blog that after the OOXML JTC1 ballot closed on September 2, the sun would rise, the birds would sing, and so on. As we are now at the end of the month and about to move into October, I can state that those things all happened. Indeed, from my perspective, September was a very good month, maybe a historic month, for open standards and open source.

This posting follows up “Install Xen 3.1 Solaris domU (64 bit) at CentOS 5 dom0 (64 bit)” at Lxer.com and gives step by step instruction how to set up VNC on OpenSolaris DomU. In general , everything seems to be already told in OpenSolaris documents.However, I believe that detailed instructions won't be useless at mean time.

Don Parris discusses how to change user Access and Preferences settings in phpGroupware.

It's been a wild ride, but I have definitely not regretted my choice to make Ubuntu a major part of my life. As a full-time user, I have been charged by Windows and Linux user alike for not following their own lemming-like mindsets.

At the large school in Mexico where I'm employed as a system manager, I proposed (and got) a Linux server to replace an old Windows 2000 file server and domain controller for the alumni. I then was faced with the task of adding 3,000 users to this new CentOS 5 server. I wasn't about to add thousands of users and their passwords one by one to the new Samba primary domain controller (PDC) system. With a little help from OpenOffice.org Calc, a utility called Expect, and shell scripts, I automated the process.

Linux software maker Red Hat yesterday announced that the latest version of its operating system would be delayed for another 30 to 60 days. The latest version of Red Hat was originally expected in August.

If for any reason you need to move your /home directory to its own partition, here you will find how to do it, this will be useful in a lot of situation, because, you run out of disk space, or because you need to reinstall your system, or because you need to have a dual boot system with two Linux distros, sharing the same home directory

I call it the $0 Laptop, because that's what I paid for it. The dead Gateway Solo 1450 I got a few months back now runs. The Gateway's previous owner abandoned it because its DC power plug pretty much disintegrated -- a common problem in these machines because the plug in question is a PC-board-mounted piece of plastic. With a new power plug in place, I decided to try to get some Linux and BSD distros on it. Xubuntu 7.04 had a promising start. After booting the live CD, I even had the panels that went missing in my other installs. But the install crashed, and on subsequent tries, those panels disappeared, so I decided to move on.

A thread on the OpenBSD-misc mailing list compared the security of SELinux in the 2.6 Linux kernel to what's available in OpenBSD. The general opinion was that SELinux and its policy language are too complex, leading Damien Miller to note, "every medium to large Linux deployment that I am aware off has switched SELinux off. Once you stray from the default configurations that the system distributors ship with, the default policies no longer work and things start to break." Ted Unangst summarized, "the problem with security by policy is that the policy is always wrong."

QEMU is an open source emulator for complete PC systems. In addition to emulating a processor, QEMU permits emulation of all necessary subsystems, such as networking and video hardware. It also permits emulation of advanced concepts, such as symmetric multiprocessing systems (up to 255 CPUs) and other processor architectures, such as ARM or PowerPC. This article explores QEMU and its architecture and shows how to emulate a guest operating system on a Linux host.

One of the discrepancies in the reputation the US has as a tech innovator is the perception that it has lagged behind Europe when it comes to mobile telephony. As one critic said rather sarcastically about this lack of progress: "Ten years and all we have to show is ring tones." The first sign of change was the 31 July announcement by the FCC that licensees will be required "to allow customers, device manufacturers, third-party application developers and others to use or develop the devices and applications of their choosing." The second aspect of this change is the availability of open phones. Not only are the phones open, but their operating systems are open too, running Linux.

When you are a MSN + IRC user (like me), Pidgin 2.1.1 will be for you. Why? Because it introduces MSNP14 support, persistant chatrooms and more!

Linux is by far the software most commonly associated with (and often mis-identified with) open source and free software, where free refers to liberty, not costs. However, access to source code, ability to modify or redistribute, and the royalty-free nature of Linux are hardly the reasons why four out of five handset OEMs have adopted Linux. In other words, mobile Linux has not been adopted because of its "free software" qualities.

Red Hat Inc., the world's biggest seller of Linux operating-system programs, said profit rose 64 percent after sales of new products topped analysts' estimates. The shares rose 5.1 percent in extended trading. Net income climbed to $18.2 million, or 9 cents a share, from $11 million, or 5 cents, a year earlier, Raleigh, North Carolina-based Red Hat said today in a statement. Sales rose 28 percent to $127.3 million for the quarter ended Aug. 31, beating analysts' estimates in a Bloomberg survey. The company also gave an earnings forecast that matched estimates.

Below are addictive 3d games for linux users to fill their time with. These games are really good and some have won awards or have been featured on magazines. Most of it is cross platform and free. You don’t have to use ‘Wine’ to be able to play as they come with Linux installers.

Windows Addiction is an unperceived phenomenon which has gotten a hold of us, and we get upset when we don’t do Windows anymore. But what is the Windows Addiction? I think there is no proper working definition for it as yet but I feel it is an obsessive compulsive use of the Windows Operating System despite the fact the we don’t want to use it anymore and we feel miserable using it but we can’t stop using it due to various fears, false beliefs and myths. Now what is so bad about Microsoft Windows and if one is hooked on using them in an obsessively compulsive manor?

Microsoft continues to virtually own the desktop operating system and Office suite desktop market. Still, its recent market behavior signals that it is not taking any chances when it comes to Linux, or any other threat, on its prized desktop. Microsoft’s revised Windows XP downgrade rights policy that quietly went into effect this summer, for example, is designed to kill two birds with one stone: jumpstart PC sales and prevent Linux desktop vendors from exploiting its Vista headaches.

The Ubuntu Linux team is planning to release Gutsy Gibbon, the latest version of its OS, tomorrow.
