Years ago, as a Network Engineer in the Air Force, I learned the importance of Univac as I studied it. My masters thesis was on the inner working of the Univac 1050II. Later Sperry Univac, and still later Linux. My forte was hex and decimal programming. But as familiar things fade away, I decided it was time for a change. Ubuntu with KDE became my passion and I am still reliant on it to perform a myriad of software task daily.

Where did open source come from?

Originally coined in 1998, the term open source came out of the free software movement, a collaborative force going strong since the dawn of computing in the 1950s. This early community was responsible for the development of many of the first operating systems, software and, in 1969, the Internet itself. Read more at http://www.ubuntu.com/project/open-source

Linux From Scratch (LFS) is a project that provides you with step-by-step instructions for building your own custom Linux system, entirely from source code.

Currently, the Linux From Scratch organization consists of the following subprojects:

LFS :: Linux From Scratch is the main book, the base from which all other projects are derived.
BLFS :: Beyond Linux From Scratch helps you extend your finished LFS installation into a more customized and usable system.
ALFS :: Automated Linux From Scratch provides tools for automating and managing LFS and BLFS builds.
CLFS :: Cross Linux From Scratch provides the means to cross-compile an LFS system on many types of systems.
HLFS :: Hardened Linux From Scratch focuses on building an LFS system with heightened security.

Why Linux is Better

Need to monitor Linux server performance? Try these built-in command and a few add-on tools. Most Linux distributions are equipped with tons of monitoring. These tools provide metrics which can be used to get information about system activities. You can use these tools to find the possible causes of a performance problem. The commands discussed below are some of the most basic commands when it comes to system analysis and debugging server issues such as:

Finding out bottlenecks.
Disk (storage) bottlenecks.
CPU and memory bottlenecks.
Network bottlenecks.
