Though Red Hat is poised to roll out its much-anticipated Red Hat Enterprise Linux 5 release shortly, work still continues on previous versions of RHEL. This week Red Hat rolled out a beta release of its fifth update to RHEL 4 officially tagged Red Hat Enterprise Linux 4.5, providing users with a small taste of the virtualization that is to come in RHEL 5.

A new version of WinAROS has been released. "WinAROS is a preinstalled AROS Environment that runs under Windows, using QEMU. WinAROS is a way to use AROS under Windows and try your programs, made with AmiDevCpp. The new Version comes with Themes and GhostScript installed."

"Almost a year ago the Linux WLAN developers announced the switch to a new WLAN subsystem. Today the new system finally found its way into the mm kernel tree of Andrew Morton. In May and April 2006 it became clear that the devicescape WLAN stack will be the future base for the Linux WLAN drivers. The aim was to overcome the current situation of having several different subsystems for different drivers and to create a common, well documented subsystem. The new stack will feature a reworked driver for Broadcom bcm43xx drivers as well as a Ralink rt2x00 driver. And, as already mentioned, Intel's ipw3945 driver will be implemented without the need for a proprietary deamon."

"One of the areas where Linux has rapidly progressed is in the field of virtualization. Among the virtualization options are Xen, QEMU, QEMU with KVM, and VMWare. With Fedora 7 it's so easy to use KVM virtualization that you can start virtualizing your favorite operating system and barely even touch the keyboard! In this guide we will tell you how as we work on virtualizing a battery of operating systems from Microsoft Windows Vista to Mandrake 9.2."

A sedate Dell posted fourth quarter results that didn't horrify investors even though its PC and notebook sales fell in dramatic fashion. Dell reported USD 14.4bn in revenue – down from USD 15.2bn in the same period last year. The company's net income came in at USD 673m, which marks quite the fall from last year's haul of USD 1bn. Officials declined to face off against financial analysts and discuss the results in a conference call as is customary, primarily because Dell counts its fourth quarter results as 'preliminary' due to a pair of investigations into its past accounting.

World wide web father Tim Berners-Lee told politicians on Thursday that it's critical to shield his seminal innovation from control by a single company or country. A top priority for policymakers going forward must be "making sure the web itself is the blank sheet, the blank canvas, something that does not constrain the innovation that's around the corner," the knighted engineer told a US House of Representatives panel that writes internet and telecommunications laws.

"Poke around the net for a while searching for information on what it's like to switch to a Mac, and you'll quickly get a face full of hyperbole, zealots, platform bigots, feature weenies, and naysayers - from both the Windows and Mac camps. But there are precious few places to get an honest word about what it's like to switch, other than some deeply technical face-offs. So, I've been taking notes for the past few years, and thought I'd write them down."

"2007 will go down in history as the year Sun Microsystems gave up the reins of the Java platform, releasing it under an open source license to the Java developer community. In this article, Java developer Elliotte Rusty Harold predicts new directions for the Java platform, in everything from scripting to bug fixing to new syntax."

"MINIX is an operating system designed for 'resource limited' or embedded computer systems. Versions 1 and 2 were teaching operating systems upon which the famous book, Operating Systems Design and Implementation, by Andrew S Tanenbaum and Albert S Woodhull, is based and also was the inspiration for Linux. With this latest release, version 3, MINIX aims to be a complete, stable, secure desktop operating system for everyday use. Does it live up to those claims? Read on to find out."

I've been an Arch user for roughly 3 years. I'm pretty much familiar with it all - The way it boots, its configuration and its package management. I've also heard a lot of good things about Ubuntu, and wanted to try it for a long time. So, two weeks ago, I took the plunge. These are my findings.
