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.

Wonder what Apple will come out with this weekend that linux has been doing for years.
Tested the motors from what I got at Goodwill. They work. I did not test the rc receivers from two of them. Need to start doing research. Pulled a couple of motors from some old old cdrom. Tested them and they work. They are going into a toy for an xmas gift.
Bought an adult bike from Goodwill for 5 dollars. Have a lot of work to do in it, but looks like it will be fine. Have to adapt...
