Lines Were Drawn looks at a group of Mississippi teenagers whose entire high school experience, beginning in 1969, was under federal court-ordered racial integration. Through oral histories and other research, this group memoir considers how the students, despite their markedly different backgrounds, shared a common experience that greatly influences their present interactions and views of the world—sometimes in surprising ways. The book is also an exploration of memory and the ways in which the same event can be remembered in very different ways by the participants.The editors (proud members of Murrah High School’s Class of 1973) and more than fifty students and teachers address the reality of forced desegregation in the Deep South from a unique perspective—that of the faculty and students who experienced it and made it work, however briefly. The book tries to capture the few years in which enough people were so willing to do something about racial division that they sacrificed immediate expectations to give integration a true chance.This period recognizes a rare moment when the political will almost caught up with the determination of the federal courts to finally do something about race. Because of that collision of circumstances, southerners of both races assembled in the public schools and made integration work by coming together, and this book seeks to capture those experiences for subsequent generations.

Command Line Kung Fu information: Become a Linux Ninja with Command Line Kung Fu Do you think you have to lock yourself in a basement reading cryptic man pages for months on end in order to have ninja like command line skills? In reality, if you had someone share their most powerful command line tips, tricks, and patterns you'd save yourself a lot of time and frustration. What if you could look over the shoulder of a good friend that just happened to be a command line guru? What if they not only showed you the commands they were using, but why they were using them and exactly how they worked? And what if that friend took the time to write all of it down so you can refer to it whenever you liked? Well, a friend did just that. Command Line Kung Fu is packed with dozens of tips and over 100 practical real-world examples. You won't find theoretical examples in this book. The examples demonstrate how to solve actual problems and accomplish worthwhile goals. The tactics are easy to find, too. Each chapter covers a specific topic and groups related tips and examples together. For example, if you need help extracting text from a file look in the "Text Processing and Manipulation" chapter. Also, a comprehensive index is included. If you want to find every example where a given command is used -- even if it's not the main subject of the tip -- look in the index. It will list every single place in the book where that command appears.
