Mac OS X Internals

Mac OS X was released in March 2001, but many components, such as Mach and BSD, are considerably older. Understanding the design, implementation, and workings of Mac OS X requires examination of several technologies that differ in their age, origins, philosophies, and roles.Mac OS X Internals: A Systems Approach is the first book that dissects the internals of the system, presenting a detailed picture that grows incrementally as you read. For example, you will learn the roles of the firmware, the bootloader, the Mach and BSD kernel components (including the process, virtual memory, IPC, and file system layers), the object-oriented I/O Kit driver framework, user libraries, and other core pieces of software. You will learn how these pieces connect and work internally, where they originated, and how they evolved. The book also covers several key areas of the Intel-based Macintosh computers.A solid understanding of system internals is immensely useful in design, development, and debugging for programmers of various skill levels. System programmers can use the book as a reference and to construct a better picture of how the core system works. Application programmers can gain a deeper understanding of how their applications interact with the system. System administrators and power users can use the book to harness the power of the rich environment offered by Mac OS X. Finally, members of the Windows, Linux, BSD, and other Unix communities will find the book valuable in comparing and contrasting Mac OS X with their respective systems.Mac OS X Internals focuses on the technical aspects of OS X and is so full of extremely useful information and programming examples that it will definitely become a mandatory tool for every Mac OS X programmer.

IPv6 Core Protocols Implementation

The authoritative reference text on KAME and IPv6!IPv6 was introduced in 1994 and has been in development at the IETF for over 10 years. It has now reached the deployment stage. KAME, the de-facto open-source reference implementation of the IPv6 standards, played a significant role in the acceptance and the adoption of the IPv6 technology. The adoption of KAME by key companies in a wide spectrum of commercial products is a testimonial to the success of the KAME project, which concluded not long ago. This book is the first and the only one of its kind, which reveals all of the details of the KAME IPv6 protocol stack, explaining exactly what every line of code does and why it was designed that way. Through the dissection of both the code and its design, the authors illustrate how IPv6 and its related protocols have been interpreted and implemented from the specifications. This reference will demystify those ambiguous areas in the standards, which are open to interpretation and problematic in deployment, and presents solutions offered by KAME in dealing with these implementation challenges.About the AuthorsQing Li is a senior architect at Blue Coat Systems, Inc. leading the design and development efforts of the next-generation IPv6 enabled secure proxy appliances. Qing holds multiple US patents. Qing is a contributing author of the book titled Handbook of Networked and Embedded Control Systems published in June 2005. He is the author of the embedded systems development book titled Real-Time Concepts for Embedded Systems published in April 2003. Tatuya Jinmei Ph.D. is a research scientist at Corporate Research & Development Center, Toshiba Corporation. He had been a core developer of the KAME project since the launch of the project through its conclusion. In 2003, he received the Ph.D. degree from Keio University, Japan, based on his work at KAME. Keiichi Shima is a senior researcher at Internet Initiative Japan Inc. He was a core developer of the KAME project from 2001 to the end of the project and developed Mobile IPv6/NEMO Basic Support protocol stack. He is now working on the new mobility stack (the SHISA stack) for BSD operating systems.IPv6 Core Protocols Implementation addresses with technical depth and clarity an IPv6 implementation on University California Berkeley Source Code Distribution (BSD), from the KAME project that was based in Japan, which is both a commercial and academic success in the world wide networking implementation market. The book begins with an overview of the KAME project and source code distribution, and then provides a concise, but thorough overview of the BSD network implementation. Then the book provides the architecture and an implementation code base component for IPv6 added to the current BSD TCP/IP Internet Protocol layer code base, the implications of the changes to the Transport Layer, and then provides a review of the BSD Socket Application Interface changes for IPv6. The authors did a very good job of representing the source code implementation and it was easy to read and comprehend, with discussion for each programmatic presentation of the code base functions and data structures. This book will be valuable to both networking architects and programmers that have to absorb and understand the implementation of IPv6 within the TCP/IP network implementation and reference model. The book was a pleasure to read and reminded me of the TCP/IP technical books by the late Dr. Richard Stevens, and afforded me the same technical depth. CTO IPv6 Forum www.ipv6forum.com ~Jim Bound. 

• Covering a snapshot version of KAME dated April 2003 based on FreeBSD 4.8
• Extensive line-by-line code listings with meticulous explanation of their rationale and use for the KAME snapshot implementation, which is generally applicable to most recent versions of the KAME IPv6 stack including those in recent releases of BSD variants
• Numerous diagrams and illustrations help in visualizing the implementation 
• In-depth discussion of the standards provides intrinsic understanding of the specifications

iSCSI

There are two core ways to implement Storage Area Networks (SANs) -- the traditional way, Fibre Channel, which is a direct link via cable, and the emerging way, IP SANs, whereby you access storage via the internet. Within IP SANs there are a number of important protocols including FCIP, iFCP, and iSCSI. iSCSI is an evolution of SCSI protocol that allows computers to talk to their hard disks, tapes, etc. The new iSCSI protocol carries SCSI commands over IP networks to facilitate data transfers over intranets and to manage storage over long distances. This book offers System and Storage engineers a quick and easy way to become familiar with the iSCSI protocols, with needed insight to its applicability.

Head First Design Patterns

You're not alone. At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns--the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on...something else. Something more challenging. Something more complex. Something more fun. You want to learn about the patterns that matter--why to use them, when to use them, how to use them (and when NOT to use them). But you don't just want to see how patterns look in a book, you want to know how they look "in the wild". In their native environment. In other words, in real world applications. You also want to learn how patterns are used in the Java API, and how to exploit Java's built-in pattern support in your own code. You want to learn the real OO design principles and why everything your boss told you about inheritance might be wrong (and what to do instead). You want to learn how those principles will help the next time you're up a creek without a design pattern. Most importantly, you want to learn the "secret language" of Design Patterns so that you can hold your own with your co-worker (and impress cocktail party guests) when he casually mentions his stunningly clever use of Command, Facade, Proxy, and Factory in between sips of a martini. You'll easily counter with your deep understanding of why Singleton isn't as simple as it sounds, how the Factory is so often misunderstood, or on the real relationship between Decorator, Facade and Adapter. With Head First Design Patterns, you'll avoid the embarrassment of thinking Decorator is something from the "Trading Spaces" show. Best of all, in a way that won't put you to sleep! We think your time is too important (and too short) to spend it struggling with academic texts. If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, Head First Design Patterns will load patterns into your brain in a way that sticks. In a way that lets you put them to work immediately. In a way that makes you better at solving software design problems, and better at speaking the language of patterns with others on your team.

Patterns of Enterprise Application Architecture

The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform. This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts. Armed with this book, you will have the knowledge necessary to make important architectural decisions about building an enterprise application and the proven patterns for use when building them.  The topics covered include  Dividing an enterprise application into layers  The major approaches to organizing business logic  An in-depth treatment of mapping between objects and relational databases  Using Model-View-Controller to organize a Web presentation  Handling concurrency for data that spans multiple transactions  Designing distributed object interfaces

Refactoring to Patterns

In 1994, Design Patterns changed the landscape of object-oriented development by introducing classic solutions to recurring design problems. In 1999, Refactoring revolutionized design by introducing an effective process for improving code. With the highly anticipated Refactoring to Patterns, Joshua Kerievsky has changed our approach to design by forever uniting patterns with the evolutionary process of refactoring. This book introduces the theory and practice of pattern-directed refactorings: sequences of low-level refactorings that allow designers to safely move designs to, towards, or away from pattern implementations. Using code from real-world projects, Kerievsky documents the thinking and steps underlying over two dozen pattern-based design transformations. Along the way he offers insights into pattern differences and how to implement patterns in the simplest possible ways. Coverage includes: A catalog of twenty-seven pattern-directed refactorings, featuring real-world code examples Descriptions of twelve design smells that indicate the need for this books refactorings General information and new insights about patterns and refactoring Detailed implementation mechanics: how low-level refactorings are combined to implement high-level patterns Multiple ways to implement the same pattern?and when to use each Practical ways to get started even if you have little experience with patterns or refactoring Refactoring to Patterns reflects three years of refinement and the insights of more than sixty software engineering thought leaders in the global patterns, refactoring, and agile development communities. Whether you're focused on legacy or greenfield development, this book will make you a better software designer by helping you learn how to make important design changes safely and effectively.

Refactoring Workbook

Refactoring has gained widespread acceptance in the software engineering community as a proven means of improving software. Martin Fowler's seminal book on this topic, Refactoring, has been used in the classroom to explain that existing code could be improved and enhanced without significantly altering the fundamental structure of an application. But many find that this concept has a steep learning curve that inhibits its use. In this new book, William Wake offers a more introductory look at this important topic. The author outlines a proven workbook approach to learning and applying refactoring to "everyday" projects. This approach relies on examples that force the student to apply the main concepts of refactoring. As a result, readers gain thorough knowledge of how refactoring can help improve their software.

Refactoring

Your class library works, but could it be better? Refactoring: Improving the Design of Existing Code shows how refactoring can make object-oriented code simpler and easier to maintain. Today refactoring requires considerable design know-how, but once tools become available, all programmers should be able to improve their code using refactoring techniques. Besides an introduction to refactoring, this handbook provides a catalog of dozens of tips for improving code. The best thing about Refactoring is its remarkably clear presentation, along with excellent nuts-and-bolts advice, from object expert Martin Fowler. The author is also an authority on software patterns and UML, and this experience helps make this a better book, one that should be immediately accessible to any intermediate or advanced object-oriented developer. (Just like patterns, each refactoring tip is presented with a simple name, a "motivation," and examples using Java and UML.) Early chapters stress the importance of testing in successful refactoring. (When you improve code, you have to test to verify that it still works.) After the discussion on how to detect the "smell" of bad code, readers get to the heart of the book, its catalog of over 70 "refactorings"--tips for better and simpler class design. Each tip is illustrated with "before" and "after" code, along with an explanation. Later chapters provide a quick look at refactoring research. Like software patterns, refactoring may be an idea whose time has come. This groundbreaking title will surely help bring refactoring to the programming mainstream. With its clear advice on a hot new topic, Refactoring is sure to be essential reading for anyone who writes or maintains object-oriented software. --Richard DraganTopics Covered: Refactoring, improving software code, redesign, design tips, patterns, unit testing, refactoring research, and tools.
