GNU/Linux and free software are a boon to a lot of businesses, and a thorn in the sides of others. Both the friends and enemies of Linux are realizing that Linux is important, and that it is here to stay. HP is leveraging Linux to try to return from the brink of financial ruin. As colleges and other schools around the country teeter on the verge of bankruptcy, many are moving to open source textbooks as a lower cost alternative. Free software is freeing people from the shakedown that is cable television. Finally, Microsoft has broken down and contributed code to a GPL version 3-licensed project.

This morning I noticed Ubuntu 11.10 Oneric Ocelot is here. After switching to Linux Mint when Ubuntu started using Unity as the default desktop, I'm wondering if Ubuntu 11.10 is just another Ubuntu headache or the real deal?

As always, the free software community and the technology world in general are in a constant state of flux. Once you get used to the way that things operate, you can be certain that they are going to change. A lot of surprising events occurred recently: Intel teamed up with Google, Microsoft teamed up with Arm, and a controversy brewed over whether Windows 8 will lock out GNU/Linux, FreeBSD, and other free operating systems. The world of free software is NEVER boring.

The Free Software movement has truly become a global phenomenon. Today, I found a piece of legislation that is currently before the Philippines’ House of Representatives that reads like it was written by Doctor Richard Stallman himself! There is absolutely no doubt in my mind that the world has really changed, and it will continue to do so. Ubuntu is evolving as well: I will discuss Ubuntu’s possible move to a rapid release cycle, similar to the one that Firefox recently shifted to. The third story in this week’s round up discusses how the Acer Aspire One has grown into an elder statesman of the GNU/Linux netbook movement.

I embrace the uniqueness of the free software and open source communities, and this edition of TLWIR focuses on some of the finest examples of that which differentiates our way of thinking.

As we have mentioned before, graphical configuration of most things in openSUSE is pretty easy. Command line configuration is pretty easy too and once known can be quicker than the GUI. We will step you through both configurations as we build up in this series to PXE Installation server.

This week was punctuated by three phenomenal stories that show how free software is prospering. C++ has been one of the staples of free software for several decades. It is the programming language of choice for a lot of programmers, and it just got a brand new revision. Google has provided some much-needed backing of free software by buying Motorola Mobility and its associated patent pool. Microsoft has waived a backhanded truce flag at the Linux community by saying that it no longer sees Linux as a threat.

Typically when you want to measure tomcat performance, you will set up the client on a separate machine so that when you are doing testing the client resource usage does not impact the test.

This week’s edition of The Linux Week in Review maintains a focus on one of the core principles of success: keeping it simple and stupid. Every situation does not call for us to have a PhD in computer science, or Bill Gates’ bank account. Often times, simple is better. Libreoffice can perform what most businesses need at a great price: free. NASA recently decided to, in the vernacular of the streets, keep it real by ditching expensive proprietary solutions, coming back to Earth, and embracing free software. Asus decided to leave ostentatious excess behind, and instead introduced its low-profile, but elegant, X101.
