In this tutorial I will describe how to setup and expand a replicated Glusterfs Volume on Debian Squeeze. Glusterfs is a clustered, scalable network file system licensed under the GNU GPL. Glusterfs should be able to handle petabytes of data anbd thousands of clients – may be I will try that later .. In my tutorial I will use only four storage server and one client.

Valve is currently exploring possibilities for "wearable computing" and they're also getting into blogging...

In my past several articles, I've looked at various packages to do all kinds of science. Sometimes, however, there just isn't a tool to solve a particular problem. That's the great thing about science. There is always something new to discover and study. But, this means it's up to you to develop the software tools you need to do your analysis. This article takes a look at the GNU Scientific Library, or GSL. This library is the Swiss Army library of routines that you will find useful in your work.

A look at the new features in Fedora 17, including some screenshots.

KDE4 Activities are misunderstood, which is unfortunate because they are powerful, fast tools for organizing complex workflows. So what's the point, who needs them, and how do you use them?

Fedora 17’s Beefy Miracle finally hits Beta, after a two-week delay to the original release. The Beta includes GNOME 3.4, GIMP 2.8, and Linux Kernel 3.3...

hostapd, the Host Access Point daemon, provides strong WPA2 encryption and authentication on Linux-based wireless access points. It is fairly simple to configure, supports WPA2-Personal and Enterprise, and also provides a unique modification to WPA2-Personal that makes it both strong and simple to administer.

The recently released Who Writes Linux kernel contributor list reveals that some of the usual supporters of Linux -- Red Hat, SUSE, IBM, Intel, Oracle -- remain firmly behind the open source OS. There has also been a lot of attention on the other contributors, which now include Microsoft. What I find most fascinating about the Linux contributor list are the contributors that show some new direction and potential for Linux, in this case the processor players.

When Rackspace launched new cloud services on OpenStack this week, the company essentially declared war against proprietary cloud computing platforms and closed systems. Here's why.

Somewhere around 2002 I put my eyes on a "Linux special" edition of a popular computer magazine containing no less than 5 Mandrake installation CDs. I called in a geekier friend of mine and spent the whole afternoon reading the huge instructions leaflet and performing all the required steps. I was very, very excited and eager to explore the new possibilities. But...

This guide explains how you can configure DNSSEC on BIND9 on Debian Squeeze and Ubuntu 11.10. It covers how to enable DNSSEC on authoritative nameservers (master and slave) and on resolving nameservers, creation of keys (KSKs and ZSKs), signing of zones, key rolling with rollerd, zone file checking with donuts, creation of trust anchors, using DLV (DNSSEC look-aside validation), and getting your DS records into the parent's zone.

I have a confession: I believe in OpenStack — the open source cloud platform. But I’m not suggesting that it will dominate cloud computing. Similar to how the Linux industry evolved to support multiple distributions (Red Hat, SUSE, Ubuntu, etc.), I believe the cloud computing industry will support many open source options — OpenStack, Citrix CloudStack, Eucalyptus, and additional options from Red Hat, VMware and so on.

The Chakra Development Team, through Anke Boersma, proudly announced yesterday, April 16th, the immediate availability for download of the Chakra GNU/Linux 2012.04 operating system.

The Google Play Store "Traps" pirates, even though they aren't pirates! This is how you can break free!

Yesterday I reported on it appearing the 295.40 NVIDIA Linux driver effectively fell off a cliff with a range of performance regressions, stability issues, and other problems. This issue has been confirmed by NVIDIA and they're working to address the situation...

Computer languages and software interfaces may fall under copyright protection if Oracle succeeds in its Java lawsuit against Google. Amazingly, "copyfighters" appear to have paid little or no notice to this rare extension of copyright into new realms. But the consequences and costs for the software industry could be enormous.

Kubuntu gets new sponsorship, ChromeOS gets a new look and Debian stick with the tried and true

OpenTTD is a free and open source reimplementation of the Microprose game "Transport Tycoon Deluxe" with lots of new features and enhancements. The game is quite popular among Linux gamers and can be played with free graphics files from the openttd-opengfx package and optional sound files from the openttd-opensfx package (which is non-free). These files can be downloaded from game itself.

Linus Torvalds announced this weekend, April 15th, that the third Release Candidate of the upcoming Linux 3.4 kernel is available for download and testing.

On March 30th,2012, at Beijing, China, a grand meeting called KDE China User was held. This meeting has provided KDE users, community members and technophiles concerned about KDE’s development with a nice “face-to-face” opportunity, to discuss about KDE’s latest and cutting edge technology trends.
