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.

"Version 4.0.1 released 25 November 2014. Version 4 of DragonFly brings Haswell graphics support, 3D acceleration, and improved performance in extremely high-traffic networks. DragonFly now supports up to 256 CPUs, Haswell graphics (i915), concurrent pf operation, and a variety of other devices. As announced during the 3.8 release, DragonFly BSD is 64-bit only. No 32-bit installation images have been generated, and no compatibility work is being done for 32-bit systems. Changes since DragonFly 3.8: new device files /dev/upmap and /dev/kpmap have been added. These memory mappable drivers allow for a per process or common to the kernel shared memory space. The objective is to allow kernel-provided information to be directly read from memory, without having to pay the cost of a traditional system call."
