One of the greatest frustrations in most software projects is version control: the art of managing changes to information. Today's increasingly fast pace of software development--as programmers make small changes to software one day only to undo them the next--has only heightened the problem; consecutive work on code or single-programmer software is a rare sight these days. Without careful attention to version control, concurrent and collaborative work can create more headaches than it solves. This is where Subversion comes into play. Written by members of the Subversion open source development team, "Version Control with Subversion" introduces the powerful new versioning tool designed to be the successor to the Concurrent Version System or CVS. CVS users will find the "look and feel" Subversion comfortably familiar, but under the surface it's far more flexible, robust, and usable, and more importantly, it improves on CVS's more notable flaws. The book begins with a general introduction to Subversion, the basic concepts behind version control, and a guided tour of Subversion's capabilities and structure. With thorough attention to detail, the authors cover every aspect of installing and configuring Subversion for managing a programming project, documentation, or any other team-based endeavor. Later chapters cover the more complex topics of branching, repository administration, and other advanced features such as properties, externals, and access control. The book ends with reference material and appendices covering a number of useful topics such as a Subversion complete reference and troubleshooting guide. "Version Control with Subversion" aims to be useful to readers of widelydifferent backgrounds, from those with no previous experience in version control to experienced sysadmins. If you've never used version control, you'll find everything you need to get started in this book. And if you're a seasoned CVS pro, this book will help you make a painless leap into Subversion.

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.

There's nothing that hard-core Unix and Linux users are more fanatical about than their text editor. Editors are the subject of adoration and worship, or of scorn and ridicule, depending upon whether the topic of discussion is your editor or someone else's. vi has been the standard editor for close to 30 years. Popular on Unix and Linux, it has a growing following on Windows systems, too. Most experienced system administrators cite vi as their tool of choice. And since 1986, this book has been the guide for vi. However, Unix systems are not what they were 30 years ago, and neither is this book. While retaining all the valuable features of previous editions, the 7th edition of Learning the vi and vim Editors has been expanded to include detailed information on vim, the leading vi clone. vim is the default version of vi on most Linux systems and on Mac OS X, and is available for many other operating systems too. With this guide, you learn text editing basics and advanced tools for both editors, such as multi-window editing, how to write both interactive macros and scripts to extend the editor, and power tools for programmers -- all in the easy-to-follow style that has made this book a classic. Learning the vi and vim Editors includes: A complete introduction to text editing with vi: How to move around vi in a hurry Beyond the basics, such as using buffers vi's global search and replacement Advanced editing, including customizing vi and executing Unix commands How to make full use of vim: Extended text objects and more powerful regular expressions Multi-window editing and powerful vim scripts How to make full use of the GUI version of vim, called gvim vim's enhancements for programmers, such as syntax highlighting, folding and extended tags Coverage of three other popular vi clones -- nvi, elvis, and vile -- is also included. You'll find several valuable appendixes, including an alphabetical quick reference to both vi and ex mode commands for regular vi and for vim, plus an updated appendix on vi and the Internet. Learning either vi or vim is required knowledge if you use Linux or Unix, and in either case, reading this book is essential. After reading this book, the choice of editor will be obvious for you too.
