Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

A couple of weeks ago a recruiter found my profile in the web and contacted me for a job as Linux Administrator.
He asked me about my server and was very surprised that I had not tried virtualization.
I answerd that I did not any need to have a virtualization as I did not have any Windows installed in any computer at home.
I did not understand the power of virtualization then.
Last weekend I had some time and decided to start with virtualization....
Non Uniform Memory Architecture is kind of a dry subject for most. Where a bit of code or data sits in processor cache is of little importance to the average user, unless you become interested in things like virtualization (which seeks to maximize the utilization of that cache and slams face first into the issue ) or you're interested in performance testing, in which case squeezing every extra productive cycle out of the hardware becomes a pressing concern. I happen to be interested in both, so...
If anyone is thinking of buying the £350 Acer Aspire 5720 from Tesco Direct with a view to running fully virtualized guests (as I did), don't bother. The VT functionality has been disabled in the BIOS, even though the T7500 processor is completely capable of it. There is no option in the BIOS screen to enable it, and no BIOS updates on the web site.
I put this in an email to Acer technical support and was told "the issue you have described is one of a software related nature"...
