How to Set Up a High Performance Cluster (HPC) Using Debian Lenny and Kerrighed. There are many guides found on the net describing Kerrighed and how to set it up using Ubuntu and others.However, to the best of my knowledge there isn’t a step by step guide specifically designed for Kerrighed using Debian Lenny. So here it is. You can set up your own Beowulf Cluster using Debian Lenny and Kerrighed in about 50 steps. Many of the steps described here are taken straight from other guides because there are applicable here (see sources at the bottom.) Many other steps are based on my own trial and error.

While CIA Agent Carl Cummings was being taught to heel, Frank was sitting at his kitchen table, tapping away at the cramped keyboard of a cheap netbook connected to a neighbor’s unsecured WiFi network. Even this was risky, he reminded himself, so this brief session would have to be his last until he moved on.

Computer security firm Symantec announced on Monday that Shaoxing, China was malware capital of the world last month.

[Something we never have to worry all that much about, but interesting in a morbid sort of way, I thought.]

You often may need to compare one version of a file to an earlier one or check one file against a reference file. Linux provides several tools for doing this, depending on how deep a comparison you need to make.

Time to kill? Check. Running Linux? Check. Now, here’s the last piece of that puzzle: 15 current and future gaming options that don’t require Windows.

When it comes to hardware and software, IBM and Novell have a longstanding SUSE Linux business relationship. So where are the two companies heading next together? Novell and IBM provided some clues during last week’s Novell BrainShare conference. Here are the details.

An open source, Linux-based web development package that’s crammed with features. Sukrit Dhandhania takes Quanta Plus for a test drive…

I ran the command google-chrome in Konsole and then received the infamous error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory message. This problem has been coming up a lot in Mandriva. And I had to do a lot of digging to get a work around for this.

This guide explains how you can install and use KVM for creating and running virtual machines on a Fedora 12 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

Microsoft it trying to get open source and open standards excluded from a key EU document, the Digital Agenda for Europe. If it succeeds, it would be a massive setback for open source throughout the continent. EU citizens need to write to the Commissioners now.

Document Freedom Day is a global day for document liberation. It will be a day of grassroots effort to educate the public about the importance of Open Document Formats and Open Standards in general. Every year on the last wednesday in March, we celebrate his day. This year in The Netherlands in conferencecentre "Het Brandpunt" in Baarn, the former residence of the Dutch queen, we will have five speakers who will talk about the importance of open documents and open standards for the Dutch government.

Ubuntu is set to release their next Long Term Support version at the end of April, and we now have a beta version to look at and see what we can expect. There are some pretty big changes coming in Lucid Lynx, many of which are partly or fully implemented in the current beta. There are the surprising changes, the controversial changes, and the just plain cool. Though the full release is still a month away, Ubuntu 10.04 is clearly shaping up to be an impressive release.

One of the driving mantras for us is “less is more”. I want us to “clean up, simplify, streamline, focus” the user experience work that we lead. The idea is to recognize the cost of every bit of chrome, every gradient or animation or line or detail or option or gconf setting. It turns out that all of those extras add some value, but they also add clutter. There’s a real cost to them – in attention, in space, in code, in QA. So we’re looking for things to strip out, as much (or more) as things to put in.

Ubuntu 10.04 codenamed Lucid Lynx is on the verge of its final descent. A lot of new things are coming your way. Ubuntu Artwork Pool in Flickr is buzzing with activity, so is the awesome Community Contributed Themes at Ubuntu Artwork Wiki page. But apart from these eye candy, in a more subtle way, a number of new applications are also in the pipeline. Let's explore these new comers.

My love for new technology was part of my downfall today. You see, because I so love technology, I might occasionally be a little too trusting of it and perhaps a little too casual in how I deal with it. Consider this foray into Lucid Lynx a cautionary tale.

The Italian Constitutional Court just published its decision: two articles of a 2009 Italian regional law that promotes Free Software and open digital standards violate the Italian Constitution. It will be VERY interesting now to find how many other local laws (both in Italy and in OTHER countries) have similar problems...

Astrology is a set of traditions, beliefs and systems which hold that there is a connection between the movement of heavenly bodies and events that take place on Earth such as human affairs, and personality.

"I’ve been playing with the Ubuntu 10.4 beta for the past two days, and it’s bloody brilliant. You’re sick of hearing it, I know. Every Ubuntu release sends fanboys scrambling for the same, old script – the one where Ubuntu cracks the mainstream, crushes Windows and convinces the ignorant public that open source can cure cancer and inspire world peace."

Dell has announced that it will be adding Ubuntu Enterprise Cloud (UEC) to its infrastructure solutions. The company plans to offer "blueprints" for optimising deployments of UEC of Dell hardware such as the PowerEdge C-Series. UEC joins the ranks of the proprietary solutions from VMWare and Microsoft, for which Dell already offers blueprints for deployment.
