Learn Linux kernel programming, hands-on: a uniquely effective top-down approach

The Linux^® Kernel Primer is the definitive guide to Linux kernel programming. The authors' unique top-down approach makes kernel programming easier to understand by systematically tracing functionality from user space into the kernel and carefully associating kernel internals with user-level programming fundamentals. Their approach helps you build on what you already know about Linux, gaining a deep understanding of how the kernel works and how its elements fit together.

One step at a time, the authors introduce all the tools and assembly language programming techniques required to understand kernel code and control its behavior. They compare x86 and PowerPC implementations side-by-side, illuminating cryptic functionality through carefully-annotated source code examples and realistic projects. The Linux^® Kernel Primer is the first book to offer in-depth coverage of the rapidly growing PowerPC Linux development platform, and the only book to thoroughly discuss kernel configuration with the Linux build system. Coverage includes

• Data structures

• x86 and PPC assembly language

• Viewing kernel internals

• Linux process model

• User and kernel space

• Interrupts and exceptions

• Memory allocation and tracking

• Tracing subsystem behavior

• I/O interactions

• Filesystems and file operations

• Scheduling and synchronization

• Kernel boot process

• Kernel build system

Foreword

2005 marks t he 10^th birthday of Java technology. Starting out as just a programming language, Java technology has exploded into a ubiquitous technology platform that today touches the lives of people everywhere. The 10^th birthday celebration book tells the story of how Java technology came to influence technologists, then businesses, then consumers, and now has become the predominate software on the planet.

In the early 1990s, a small group of us from Sun Microsystems were given the opportunity to spend all of our time thinking of what "the next big thing in technology" would be. What we created was a hardware-independent software platform unlike any other. We thought it was pretty cool, and so did our developer friends. But at that time, I don't think that any of us really had any idea of what we had done, not to mention how it would change the world. I certainly know I didn't.

Of course, it wouldn't have happened if it wasn't for the Java developer community. Developers are the ones who made the technology a success over the years. Their ingenuity, creativity, and millions of hours of contributed help has made the platform what it is today. We're lucky to have millions of developers constantly driving it forward into the future.

Every day I hear about new and cool uses for Java technology. I'm gratified, and still constantly amazed.

Extend RUP to Drive Improvements Across the Entire IT Lifecycle

The Rational Unified Process is a powerful tool for improving software development -- but it doesn't go nearly far enough. Today's development organizations need to extend RUP to cover the entire IT lifecycle, including the cross-project and enterprise issues it largely ignores. The Enterprise Unified Process (EUP) does precisely that, enabling you to deliver systems that meet all the needs of today's businesses. Now, EUP's creator and architects present the definitive introduction to EUP, and demonstrate how to use it in your environment.

The Enterprise Unified Process systematically identifies the business and technical problems that RUP fails to address, and shows how EUP fills those gaps. Using actual examples and case studies, the authors introduce processes and disciplines for producing new software, implementing strategic reuse, "sunsetting" obsolete code and systems, managing software portfolios, and much more. Their independent, "tool agnostic" coverage will be indispensable no matter which RUP products or platforms you've invested in. Coverage includes

• Practical, step-by-step guidance for adopting EUP in midsized-to-large organizations

• Proven processes for optimizing ongoing IT operations and support

• Enterprise business modeling and architecture with EUP

• EUP disciplines for enterprise administration, people management, and software process improvement

• Using the new EUP plug-in for IBM's RUP platform

• Workflow diagrams fully consistent with RUP for easy understanding

• Detailed appendices covering EUP roles, artifacts, and terminology

EUP is the missing link that can help IT professionals achieve the full benefits of RUP in the enterprise. This book will help you discover it, master it, implement it, and succeed with it.

“When my colleague and I were first reading John Terpstra’s Samba-3 by Example, we were impressed by how easy it was to find the chapter we wanted to implement, and the ease of following his step-by-step approach. We always felt Terpstra was there with us, for every configuration line. It was like having our own personal tutor. I always take his book to every client that uses Samba. Additionally, Terpstra does something most authors don’t, he keeps his documentation up to date. When we were doing our first implementation, he just released the update that morning; we downloaded it, printed it, and implemented it. Now, to me, that is cutting-edge technology at its best.”
—Steven C. Henry

“A cook learns to follow a recipe until he has mastered the art. This is your cookbook to successful Windows networks. I followed this recipe to migrate our NT4 domain to Samba-3, and the recipe just worked great. I could not have completed this project without the Samba-3 by Example book—it brings dry, lifeless man-pages down to the reality IT support people face.”
—Geoff Scott, IT Systems Administrator, Guests Furniture Hire Pty Ltd
