I am re-earning my Linux/UNIX chops after having been tossed about and apparently losing many brain cells

to stress during the dot-bomb in Silicon Valley, CA, US the last few years. Now, I want very much to become well-versed in Linux, and to be able to help others as I have so often been helped. My dream is to become a specialist in disaster recovery and security, but that dream is
very far away at this time.
My current position as of July 15, 2006 is as a Technical Marketing Engineer for Zmanda. Zmanda is a startup company based on the open source backup software, Amanda. I may need to create a separate login for work-related participation on LQ, but, I hope to share what I learn about the Amanda Community and Enterprise Editions. I'll be getting deeply into these applications on a daily basis. An article I co-wrote my first week on the job has made it up on the company website and on Slashdot in the hardware section, and I am going to submit it to LQ here as a tutorial.
Zmanda has issued me a generic laptop with Fedora Core 4 installed (courtesy of Linux Certified). I have never been thrilled with Red Hat, but everything on the laptop works, which is more than I can say for my many home adventures in Linux. It is frustrating to have a friend say with disdain "I use Gentoo and everything works and it was easy." My (
old) Toshiba laptop will run Linux, but my wireless cards don't work. Nothing seems to like the Texas Instruments chip. As soon as I have accumulated a few paychecks, I will do computer shopping.
I am going to give the latest Mandriva a try on That Old Laptop(c) due to a positive review in Tux magazine. I would also like to try Nubuntu, and eventually use it on a new, ultra-portable laptop that would be my traveling machine. I have a Dell Inspiron running Windows 2K that is my base machine. It is a little heavy and long in the tooth for the computer world, but it suits my needs.
