FYI...a couple of linux definitions for you.

Linux
Linux (pronounced "Lee-nooks") is a freely-distributed, open operating system (OS) based on Unix, the multi-user, multi-tasking OS created by Ken Thompson and Dennis Ritchie at Bell Labs in the late '60s. Linux was written by Linus Torvalds of Finland and has been built upon by many computer scientists and hackers from around the world. Debian (pronounced "Deb'-ian") Linux is one branch of Linux's evolutionary tree.

GUIX

[Pronounced "Gwicks"] Derogatory tech support slang for Unix/Linux newbies who are used to GUIs (Graphical User Interfaces) and don't know their way around a command line interface. Hardcore Linux user are sometimes called Penguinheads.
