This book is meant for both new programmers who want to know more about how computers work and also experienced programmers who want a little bit more control over their programs than C or C++ compilers allow. All programs in this book are written for the Linux Operating System on Intel machines. There are some C programs included to aid in understanding what the Assembly programs do. If you enjoyed the DOS edition of this book, which was previously published, then you will probably like this one even more, especially if the Software Freedom and Privacy that Linux provides is important to you. This book is not just a rewrite of the DOS book. Most of it is written from scratch with a special focus on the POSIX System Calls known as exit, read, write, open, close, and lseek. Learning these calls can allow you to write almost any Linux console application. Even if you don't become an Assembly master, you can still use much of the same information and efficiency when writing code in higher-level languages after coming back with a greater understanding of pointers, conditional loops, and numbers in bases like Binary, Hexadecimal, and Octal. I fight for the users and wish to empower people to write the smallest and fastest command-line utilities possible. My birth/legal name is Chandler Klebs but for all personal and professional purposes I use the name Chastity White Rose. This is completely explained in my different books I have published. I have many books on Amazon and I am recently getting started with Smashwords. My older books are under my old name and some are under my new name. I am transgender and have vowed celibacy and this had led to some strange inspiration in my writing.I consider the book titled: "Chandler's Honesty" to be the best of all my books. It provides the most information about my journey. However I also republished my very first book "Confessions of a Confused Virgin" on Smashwords as well. The difference between my beliefs has changed a lot in the 8 year difference between these books but I am the same confused virgin I was back then, except perhaps more confused after I talked to Honesty the unicorn.
