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.

Martin L. Barrett and Clifford Wagner combine the efficiency of C with the productivity of UNIX, and give you the foundation to build stronger programming skills! This clear, concise book is written for experienced programmers, as well as those with a background in mathematics, engineering, and science. Five principles guide you through a complete course in programming: . Emphasis on software design via program and data structure design, the design of tables, data encapsulation, and the use of abstract data types solidifies all aspects of the design process. The development of C and UNIX simultaneously, yet independently of one another, allows you to develop skills in both languages, or focus on them individually. Chapter summaries, review problems, and numerous practical programming problems enable you to tie several different concepts together in a coherent scheme. Extensive examples covering scientific problems, applied mathematics, and floating point arithmetic broaden the spectrum of computer science and programming. Problems feature the ideal gas law, the accuracy of summations, root finding, the future value of an annuity, simulation, time series smoothing, image processing, integrals, descriptive statistics, fuzzy sets, and sparse arrays. A focus on basic principles gives you the groundwork for understanding data structures, analysis of algorithms, numerical analysis, computer graphics, and compiler design.

It began simply enough. A young Finnish student at the University of Helsinki named Linus Torvalds decided to develop his own computer operating system merely as a hobby. More than a decade later, this same operating system has caused nothing short of a revolution in the world of computers. Now known as Linux, Torvalds' creation was largely dismissed in the 1990s by tech pundits who claimed that it was unsuitable for the general public's computing needs. If they only knew how wrong they were! After a series of tweaks from excited developers around the world, Linux's unparalleled functionality and adaptability have now made it the main alternative to Unix and Microsoft Windows operating systems. And with good reason. System administrators realize that this robust alternative can greatly improve their operating system's reliability - and save them money, too. Linux systems are even less vulnerable to attacks by computer viruses and worms. Not surprisingly, businesses, government agencies, schools, and a wealth of other institutions are all looking to Linux to replace the Windows desktop for these same benefits. Linux in a Windows World takes an in-depth look at exactly how Linux can be brought into an organization that's currently based on Microsoft Windows systems. Featuring a litany of insider tips and techniques, Linux in a Windows World dispenses all the practical advice you need to migrate to this revolutionary open source software. Author Roderick W. Smith, himself a renowned system administrator and Linux convert, understands that the skills required to install, deploy, and maintain Linux are not easy to find. That's why he has tapped the absolute best source of information available: the Linux server experts who have made it their life's work to build and manage the Linux system. The latest in O'Reilly's line of bestselling Linux titles, Linux in a Windows World is an invaluable companion for any system administrator interested in integrating Linux into their Windows environment.
