The Library of Congress World War II Companion

The noted historian John Keegan called World War II "the largest single event in human history." More than sixty years after it ended, that war continues to shape our world. Going far beyond accounts of the major battles, The Library of Congress World War II Companion examines, in a unique and engaging manner, this devastating conflict, its causes, conduct, and aftermath. It considers the politics that shaped the involvement of the major combatants; military leadership and the characteristics of major Allied and Axis armed services; the weaponry that resulted in the war's unprecedented destruction, as well as debates over the use of these weapons; the roles of resistance groups and underground fighters; war crimes; daily life during wartime; the uses of propaganda; and much more. Drawn from the unparalleled collections of the institution that has been called "America's Memory," The Library of Congress World War II Companion includes excerpts from contemporary letters, journals, pamphlets, and other documents, as well as first-person accounts recorded by the Library of Congress Veterans History Project. The text is complemented by more than 150 illustrations. Organized into topical chapters (such as "The Media War," "War Crimes and the Holocaust," and two chapters on "Military Operations" that cover the important battles), the book also include readers to navigate through the rich store of information in these pages. Filled with facts and figures, information about unusual aspects of the war, and moving personal accounts, this remarkable volume will be indispensable to anyone who wishes to understand the World War II era and its continuing reverberations.

Understanding the Linux Kernel

In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does. This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics: Memory management, including file buffering, process swapping, and Direct memory Access (DMA) The Virtual Filesystem layer and the Second and Third Extended Filesystems Process creation and scheduling Signals, interrupts, and the essential interfaces to device drivers Timing Synchronization within the kernel Interprocess Communication (IPC) Program execution Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. This book will help you make the most of your Linux system.
