Understanding the Linux Kernel, Third Edition

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.

Java Performance Tuning, Second Edition

Performance has been an important issue for Java developers ever since the first version hit the streets. Over the years, Java performance has improved dramatically, but tuning is essential to get the best results, especially for J2EE applications. You can never have code that runs too fast. Java Peformance Tuning, 2nd edition provides a comprehensive and indispensable guide to eliminating all types of performance problems. Using many real-life examples to work through the tuning process in detail, JPT shows how tricks such as minimizing object creation and replacing strings with arrays can really pay off in improving your code's performance. Tuning J2EE applications bears many similarities to tuning J2SE apps, but important and specific considerations apply. For this reason, Java Performance Tuning, Second Edition includes four new chapters: a new chapter on J2EE application tuning in general followed by chapters on tuning JDBC, servlets and JSPs, and EJBs. Java Performance Tuning offers common-sense advice about what to tune and what to leave alone, emphasizing techniques that provide big performance gains with minimal code restructuring. It gives you crucial guidance that helps you tune without destroying your program's architecture. Blindly changing things in an effort to make a program run faster is a great way to create buggy, unmaintainable code. Java Performance Tuning teaches you to work efficiently and effectively, resulting in code that is robust, maintainable, and fast. Java Performance Tuning, Second Edition shows you how to:

• Create a performance plan


• Glean information about your program's behavior from profiling tools


• Identify bottlenecks before tuning


• Minimize the number of objects your program creates, particularly critical for J2EE applications


• Optimize the use of strings


• Avoid performance penalties from inefficient code

Enterprise JavaBeans, Third Edition

Enterprise JavaBeans was recently voted "Best Java Book" by the editors and readers of Java Developer's Journal. Readers of JavaPro named it the "Best Java Book for Experts." And Amazon.com included it in the Top Computer Books for 2000. Now the best only gets better! In the new 3rd edition, Enterprise JavaBeans has been completely revised and updated with a thorough introduction to the new 2.0 version of the EJB specification. Significantly different from the earlier version, the 2.0 specification introduces three dramatic improvements: A completely new version of container-managed persistence; local interfaces; and a totally new kind of bean called the "message driven bean." The new version of container-managed persistence (CMP) beans in 2.0 is more portable and robust than in the older 1.1 version. Most significant is the introduction of the relationship fields, which allow entity beans to declare relationships with each other as natural references. In order to make this huge leap in component relationships possible, EJB 2.0 had to redesign how entity beans are defined and interact. Our new 3rd edition examines this critical CMP model in detail. Local interfaces are thoroughly discussed as well. Local interfaces allow beans that are co-located to interact without the overhead of remote method calls. This improves the performance of beans considerably and complements the CMP relationship fields. Message driven beans are a new kind of enterprise bean based on asynchronous messaging and the Java Message service (JMS). Instead of responding to Java RMI calls, message driven beans process JMS messages sent by messaging clients. An entire chapter is devoted to message-driven beans and how to use them effectively. In addition, the 3rd edition contains an architecture overview, information on resource management and primary services, design strategies, and XML deployment descriptors.

Java Threads, Third Edition

Threads are essential to Java programming, but learning to use them effectively is a nontrivial task. This new edition of the classic Java Threads shows you how to take full advantage of Java's threading facilities and brings you up-to-date with the watershed changes in Java 2 Standard Edition version 5.0 (J2SE 5.0). It provides a thorough, step-by-step approach to threads programming. Java's threading system is simple relative to other threading systems. In earlier versions of Java, this simplicity came with tradeoffs: some of the advanced features in other threading systems were not available in Java. J2SE 5.0 changes all that: it provides a large number of new thread-related classes that make the task of writing multithreaded programs that much easier. You'll learn where to use threads to increase efficiency, how to use them effectively, and how to avoid common mistakes. This book discusses problems like deadlock, race conditions, and starvation in detail, helping you to write code without hidden bugs. Java Threads, Third Edition, has been thoroughly expanded and revised. It incorporates the concurrency utilities from java.util.concurrent throughout. New chapters cover thread performance, using threads with Swing, threads and Collection classes, thread pools, and threads and I/O (traditional, new, and interrupted). Developers who cannot yet deploy J2SE 5.0 can use thread utilities provided in the Appendix to achieve similar functionality with earlier versions of Java. Topics include:

• Lock starvation and deadlock detection


• Atomic classes and minimal synchronization (J2SE 5.0)


• Interaction of Java threads with Swing, I/O, and Collection classes


• Programmatically controlled locks and condition variables (J2SE 5.0)


• Thread performance and security


• Thread pools (J2SE 5.0)


• Thread groups


• Platform-specific thread scheduling


• Task schedulers (J2SE 5.0)


• Parallelizing loops for multiprocessor machines

In short, this new edition of Java Threads covers everything you need to know about threads, from the simplest animation program to the most complex applications. If you plan to do any serious work in Java, you will find this book invaluable. Scott Oaks is a senior software engineer for the Java Performance Engineering group at Sun Microsystems and the author of four books in the O'Reilly Java series.

J2EE and XML Development

An Introduction level book

 

Java and XML have a great synergy, they marry together to create a "Write once, run anywhere" with a "platform independent data" paradigm. The nice thing about this is that you can keep the service interface relatively stable (e.g. use XML document instead of a specific data structure). But often what people overlook is, if you choose not to expose/distribute your data model directly (using classic data structure/class), then you have to expose/distribute the meta data of the data model (in XML world, this is called schema). Once the schema is changed (as you change in the data structure/class), you are pretty much facing the same problem as in the classic data model, the communicating parties have to know what is changed and change (the parsing rule at least) accordingly. Particularly, in the internal system, the benefit of using XML interface is dramatically reduced.

The authors of book are trying to push every data model in the interface by using XML document, even the data persistence, along with various X-technologies. That is a very "dangerous mind" if not done carefully, since XML is not a panacea in design and development. Even in modeling data, XML is not one size fit all. So when is it a good idea to use XML for your data? The following is that I quoted from Ted Neward's blog,

When your data is naturally hierarchical to begin with
When exchange with foreign platforms (which is to say, platforms not native to what you're currently authoring in) is important
When pre-existing tool support (XSLT, XML viewers, import/export utilities, etc) is of paramount importance

As you can see, there are some constraints before you decide to go with XML. Not mentioning the performance overhead. Though authors mentioned that designers need to justify the usage of XML by various criteria, but this is a book about promoting XML. :) Don't be trapped.

Overall, the book contains some useful information about various XML related technologies, particularly the chapter 5 "User Interface Development" (which is quite funny for a server side development book). And the information is too general or shallow to be useful in the real world development, you need to dig more into the technology by yourself from this introduction.

There are some examples showing how the concept could be working in the real world. But they are very rudimentary. Some specs the authors used (e.g. JAX-RPC) are already upgraded or changed. As a book on such popular topics regarding J2EE and XML, it sets the bar too low.

Good coverage on XML and Java but not J2EE

The book covers a wide range of XML technologies and its implementations in Java. Most of the examples/patterns discussed in the book apply equally well or can be easily adapted for non-J2EE Java application.
Some examples use depreciated APIs, some use APIs that no longer exist in latest packages. It's not a big problem and equivalents usually can be easily found. Just be aware how fast the technologies are evolving.

Design Patterns Explained

"One of the great things about the book is the way the authors explain concepts very simply using analogies rather than programming examples—this has been very inspiring for a product I'm working on: an audio-only introduction to OOP and software development."

—Bruce Eckel

"...I would expect that readers with a basic understanding of object-oriented programming and design would find this book useful, before approaching design patterns completely. Design Patterns Explained complements the existing design patterns texts and may perform a very useful role, fitting between introductory texts such as UML Distilled and the more advanced patterns books."

—James Noble

Leverage the quality and productivity benefits of patterns—without the complexity! Design Patterns Explained, Second Edition is the field's simplest, clearest, most practical introduction to patterns. Using dozens of updated Java examples, it shows programmers and architects exactly how to use patterns to design, develop, and deliver software far more effectively.

You'll start with a complete overview of the fundamental principles of patterns, and the role of object-oriented analysis and design in contemporary software development. Then, using easy-to-understand sample code, Alan Shalloway and James Trott illuminate dozens of today's most useful patterns: their underlying concepts, advantages, tradeoffs, implementation techniques, and pitfalls to avoid. Many patterns are accompanied by UML diagrams.

Building on their best-selling First Edition, Shalloway and Trott have thoroughly updated this book to reflect new software design trends, patterns, and implementation techniques. Reflecting extensive reader feedback, they have deepened and clarified coverage throughout, and reorganized content for even greater ease of understanding. New and revamped coverage in this edition includes

• Better ways to start "thinking in patterns"
• How design patterns can facilitate agile development using eXtreme Programming and other methods
• How to use commonality and variability analysis to design application architectures
• The key role of testing into a patterns-driven development process
• How to use factories to instantiate and manage objects more effectively
• The Object-Pool Pattern—a new pattern not identified by the "Gang of Four"
• New study/practice questions at the end of every chapter

Gentle yet thorough, this book assumes no patterns experience whatsoever. It's the ideal "first book" on patterns, and a perfect complement to Gamma's classic Design Patterns. If you're a programmer or architect who wants the clearest possible understanding of design patterns—or if you've struggled to make them work for you—read this book.
