说明：  <Programming from the Ground Up> 一本介绍从零开始linux/unix下汇编程序编写的书
(<Programming from the Ground Up> This book is not a reference book, it is an introductory book. It is therefore not suitable by itself to learn how to professionally program in x86 assembly language, as some details have been left out to make the learning process smoother. The point of the book is to help the student understand how assembly language and computer programming works, not to be a reference to the subject. Reference information about a particular processor can be obtained by contacting the company which makes it.)
