In Eric Raymond's "The Art of Unix Programming", within the section called "The Basics of Unix Philosophy" there is a rule quoted by Rob Pike: "Rule 5. Data dominates. If you've chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming" At face value Rob's rule number 5 makes sense. But what is Rob actually saying? In complex software systems it might be difficult to track down and identify how the rule of evolving functions to deal with data worked. So why not use a small microscopic example instead. Taking a small program, a passive network scanner, from data structures to operations on the data structures illustrates Rob's rule number 5 perfectly. This is an interesting experience from my perspective as most of the programs and scripts I have written deal with transitionary data. What I mean by transitionary is simply find it, operate on it and/or print it then move on. Not an unusual trait in system administration centric programs. While working on a passive scanner that could also verify a port I witnessed rule number 5 occur right before by fingertips.

In the previous article we looked at what’s the use LVS, to have a system of load balancing built into the Linux kernel. As mentioned, however, LVS was born to be good in one thing: the load balance, but does not provide additional options, such as monitoring the progress of the machines on which we are balancing service and in case of trouble in one machine remove it from the active machines. To accomplish this goal and many more wel” take a look at ldirectord

"Wouldn't it be nice to just start an application at the navigation stage? Well you can. As well as: graphically feed text to Espeak or Festival, graphically display a command's output like a directory listing or a file's contents, graphically start a web browser at a specific website like a Google search with your input, and so much more! This is basic BASH and Zenity, so don't worry, it's easy!"

We have detailed the steps for installing Google Earth in Ubuntu already. One of the issues that popped up recently is the frequent crashing of Google Earth when you try to launch the app after installation in Ubuntu Maverick, Lucid. There is an easy fix for this.

I recently got into a friendly argument with a friend of mine who is very much anti-Ubuntu. He believes that Canonical is slowly but surely selling-out the GNU/Linux community to make a profit. I completely disagree with him. I have watched several interviews with Canonical's CEO, Mark Shuttleworth, and I find him to be as committed to the free software/open source principles as anyone else. I also think that he has a very adventurous streak, and he is not the type of person that likes to take the same conservative routes that many others prefer.

Microsoft has released the sources of the F# programming language as open source code under the Apache 2.0 licence. The compiler and libraries are now available as "code drops" within the F# PowerPack collection on the CodePlex web site, Microsoft's hosting platform for open source projects. Both components were previously already available to download free of charge under Microsoft's Research Shared Source License Agreement, which permits developers to use the code in non-commercial projects. The Apache licence takes things a step further and allows the unrestricted use of the F# libraries and compiler.

Scott McNealy has kept a low profile since Oracle bought his company earlier this year, but on Wednesday the former chairman and CEO of Sun Microsystems shared some thoughts on the acquisition. "Do I have a problem with Larry Ellison buying Sun? No, that's part of capitalism, as soon as we go public we're for sale, that's part of the deal," McNealy said, referring to Oracle's chairman and CEO. "And do I have a problem with him exercising his intellectual property rights? No, I don't have a problem with that. Would it be how we necessarily ran and operated? Obviously not."

Open Source Movies, also called Open Content Movies or simply Open Movies are, as the name suggests, movies that enable the end user to view and edit the production materials. Philosophically speaking, Open Movies share the same notion that lies at the heart of open source softwares. However, they are not as popular as open source softwares. As a matter of fact, they are so rare that after a decade of their presence, there are roughly dozens of them available. Apparently, Free/Libre/Open source community, a community that is so proud of itself for producing quality alternatives to proprietary products has failed to realize the importance of open movie movement.

X11 has been with us (the Linux/UNIX community) for quite some time. Well, quite some time depending upon your age; it was released in 1984. In computing terms, this is the equivalent of saying that you have been using the original black and white Mac OS for the past 26 years. When software reaches this kind of age, it becomes nearly impossible to maintain.
