Extreme Programming does not mean programming naked while rollerblading down the side of the Grand Canyon. It does mean a new approach to software development that is both radical and common-sense. Unlike many software development methodologies, XP has been accepted quickly because its core practices - particularly code sharing, test-first development, and continuous integration - resonated immediately with software developers everywhere. Instead of impressing developers with a body of theory, XP got programmers to say, "Yeah, that's how I'd like to work." Oddly enough, although most developers turn to Extreme Programming methods in order to code real, hands-on, and extensible projects quickly ("Code comes first"), most books on Extreme Programming insist on focusing on the theory and not the practice. Not the Java Extreme Programming Cookbook. Brimming with over 100 "recipes" for getting down to business and actually doing XP, the Java Extreme Programming Cookbook doesn't try to "sell" you on XP; it succinctly documents the most important features of popular open source tools for XP in Java - including Ant, Junit, HttpUnit, Cactus, Tomcat, XDoclet - and then digs right in, providing recipes for implementing the tools in real-world environments. Each recipe offers solutions that help you put an extreme programming environment together: then provides code for automating the build process and testing. Although the time saved using any one of these solutions will more than pay for the book, Java Extreme Programming Cookbook offers more than just a collection of cut-and-paste code. Each recipe also includes explanations of how and why the approach works, so you can adapt the techniques to similar situation. One of the biggest challenges facing developers today is sorting through the wide variety of tools available form various source and figuring out how to them effectively. The recipes in Java Extreme Programming Cookbook showcase how to use the most important features of these XP tools. Many of these tools are geared towards unit testing, while others are invaluable for continuous integration; with these practical examples, you'll be able to choose the most effective tools to accomplish your goals, then implement them in a cohesive development environment quickly.

For many Java developers, web services appeared to come out of nowhere. Its advantages are clear: web services are platform-independent (like Java itself), language-agnostic (a clear advantage over Java RMI), can easily be tunneled through firewalls (an obvious benefit to anyone who has dealt with modern enterprise networks), object-oriented (we all know about that), and tends to be loosely coupled (allowing more flexible application development). But these advantages have been obscured by a cloud of hype and a proliferation of jargon that are difficult to penetrate. What are SOAP, UDDI, WSDL, and JAXM? To say nothing of JAXR, tModels, category bags, WSFL, and other friends? And assuming that you understand what they are, how do you do anything with them? Do they live up to their promises? Are they really the future of network computing, or a dead end? Java Web Services gives the experienced Java developer a way into the Web Services world. It helps you to understand what's going on, what the technologies mean and how they relate, and shows Java developers how to put them to use to solve real problems. You'll learn what's real and what isn't; what the technologies are really supposed to do, and how they do it. Java Web Services shows you how to use SOAP to perform remote method calls and message passing; how to use WSDL to describe the interface to a web service or understand the interface of someone else's service; and how to use UDDI to advertise (publish) and look up services in each local or global registry. Java Web Services also discusses security issues, interoperability issues, integration with other Java enterprise technologies like EJB; the work being done on the JAXM and JAX-RPC packages, and integration with Microsoft's .NET services. The web services picture is still taking shape; there are many platforms and APIs to consider, and many conflicting claims from different marketing groups. And although web services are inherently language-independent, the fit between the fundamental principles on which Java and web services are based means that Java will almost certainly be the predominant language for web services development. If you're a Java developer and want to climb on the web services bandwagon, or if you only want to "kick the tires" and find out what web services has to offer, you will find this book indispensable.

This guide takes a step-by-step approach to teaching developers how to build real graphics applications using Cocoa. By showing the basics of an application in one chapter and then layering additional functionality onto that application in subsequent chapters, the book keeps readers interested and motivated. Readers will see immediate results, and then go on to build onto what they've already achieved. The book is divided into four major parts: Part I introduces the Mac OS X graphical user interface (Aqua) from a developer's point of view, Cocoa developer tools (such as the Interface Builder, Project Builder, and gdb debugger), object-oriented concepts, the Objective-C language in which Cocoa is written, and the basics of Cocoa programming itself; Part II focuses on building the first complete application, calculator, a simple four-function calculator. The chapters in this part of the book extend the application, piece by piece, by introducing such features as nibs, icons, delegation, resizing, events, and responders. Part III focuses on building an application called MathPaper, which is similar to a word processor but which instead solves mathematical expressions the user supplies. The chapters in this part of the book extend MathPaper by developing both the front and back ends using a variety of Cocoa classes and methods. They introduce Cocoa'sdocument-based architecture, tasks, pipes, Rich Text format, handling document files, and using Quartz to draw in windows. Part IV focuses on building the GraphPaper application, a more complex multithreading application that graphs mathematical functions in multiple dimensions and that uses mouse-over capabilities to identify graph points. The chapters in this part of the book add more advanced Mac OS X features such as multithreading, colour, mouse events, zoom buttons, pasteboards, services, preferences, and the defaults database.

XML is a text-based markup language that has taken the programming world by storm. More powerful than HTML yet less demanding than SGML, XML has proven itself to be flexible and resilient. XML is the perfect tool for formatting documents with even the smallest bit of complexity, from Web pages to legal contracts to books. However, XML has also proven itself to be indispensable for organizing and conveying other sorts of data as well, thus its central role in web services like SOAP and XML-RPC. As the Perl programming language was tailor-made for manipulating text, few people have disputed the fact that Perl and XML are perfectly suited for one another. The only question has been what's the best way to do it. That's where this book comes in. Perl & XML is aimed at Perl programmers who need to work with XML documents and data. The book covers all the major modules for XML processing in Perl, including XML::Simple, XML::Parser, XML::LibXML, XML::XPath, XML::Writer, XML::Pyx, XML::Parser::PerlSAX, XML::SAX, XML::SimpleObject, XML::TreeBuilder, XML::Grove, XML::DOM, XML::RSS, XML::Generator::DBI, and SOAP::Lite. But this book is more than just a listing of modules; it gives a complete, comprehensive tour of the landscape of Perl and XML, making sense of the myriad of modules, terminology, and techniques. This book covers: *parsing XML documents and writing them out again *working with event streams and SAX *tree processing and the Document Object Model *advanced tree processing with XPath and XSLT Most valuably, the last two chapters of Perl & XML give complete examples of XML applications, pulling together all the tools at your disposal. All together, Perl & XML is the single book that gives you a solid grounding in XML processing with Perl.

The Korn shell is an interactive command and scripting language for accessing Unix(r) and other computer systems. As a complete and high-level programming language in itself, it's been a favorite since it was developed in the mid 1980s by David G. Korn at AT&T Bell Laboratories. Knowing how to use it is an essential skill for serious Unix users. Learning the Korn Shell shows you how to use the Korn shell as a user interface and as a programming environment. Writing applications is often easier and quicker with Korn than with other high-level languages. Because of this, the Korn shell is the most often used shell in commercial environments and among inexperienced users. There are two other widely used shells, the Bourne shell and the C shell. The Korn shell, or ksh, has the best features of both, plus many new features of its own. ksh can do much to enhance productivity and the quality of a user's work, both in interacting with the system, and in programming. The new version, ksh93, has the functionality of other scripting languages such as awk, icon, Perl, rexx, and tcl. Learning the Korn Shell is the key to gaining control of the Korn shell and becoming adept at using it as an interactive command and scripting language. Prior programming experience is not required in order to understand the chapters on basic shell programming. Readers will learn how to write many applications more easily and quickly than with other high-level languages. In addition, readers will also learn about Unix utilities and the way the Unix operating system works in general. The authors maintain that you shouldn't have to be an internals expert to use and program the shell effectively. The second edition covers all the features of the current version of the Korn shell, including many new features not in earlier versions of ksh93, making it the most up-to-date reference available on the Korn shell. It compares the current version of the Korn shell to several other Bourne-compatible shells, including several Unix emulation environments for MS-DOS and Windows. In addition, it describes how to download and build ksh93 from source code. A solid offering for many years, this newly revised title inherits a long tradition of trust among computer professionals who want to learn or refine an essential skill.

One of Java's most striking claims is that it provides a secure programming environment. Yet despite endless discussion, few people understand precisely what Java's claims mean and how it backs up those claims. If you're a developer, network administrator or anyone else who must understand or work with Java's security mechanisms, Java Security is the in-depth exploration you need. Java Security, 2nd Edition, focuses on the basic platform features of Java that provide security--the class loader, the bytecode verifier, and the security manager--and recent additions to Java that enhance this security model: digital signatures, security providers, and the access controller. The book covers the security model of Java 2, Version 1.3, which is significantly different from that of Java 1.1. It has extensive coverage of the two new important security APIs: JAAS (Java Authentication and Authorization Service) and JSSE (Java Secure Sockets Extension). Java Security, 2nd Edition, will give you a clear understanding of the architecture of Java's security model and how to use that model in both programming and administration. The book is intended primarily for programmers who want to write secure Java applications. However, it is also an excellent resource for system and network administrators who are interested in Java security, particularly those who are interested in assessing the risk of using Java and need to understand how the security model works in order to assess whether or not Java meets their security needs.

Data is the lifeblood of modern business, and modern data centres have demanding requirements for size, speed, and reliability. Storage Area Networks (SANs) and Network Attached Storage (NAS) allow organizations to manage and back up huge file systems quickly, thereby keeping their lifeblood flowing. W. Curtis Preston's insightful book takes you through the ins and outs of building and managing large data centres using SANs and NAS. Network administrators are aware that multi-terabyte data stores are common and petabyte data stores are starting to appear. Given this much data, how can they ensure that it is available all the time, that access times and throughput are reasonable, and that the data can be backed up and restored in a timely manner? SANs and NAS provide solutions that help work through these problems, with special attention to the difficulty of backing up huge data stores. This book explains the similarities and differences of SANs and NAS to help determine which, or both, of these complementing technologies are appropriate for your network. Using SANs, for instance, is a way to share multiple devices (tape drives and disk drives) for storage, while NAS is a means for centrally storing files so they can be shared. Preston examines each technology with a vendor neutral approach, starting with the building blocks of a SAN and how they can be assembled for effective storage solutions. He covers day-to-day management and backup and recovery for both SANs and NAS in detail.

The Web services architecture offers a new way to think about and implement application-to-application integration and interoperability that makes the development platform irrelevant. Two applications, regardless of operating system, programming language, or any other technical implementation detail, communicate using XML messages over open Internet protocols such as HTTP or SMTP. The Simple Open Access Protocol (SOAP) is a specification that details how to encode that information and has become the messaging protocol of choice for Web services. This is a detailed guide to using SOAP and other Web services standards - WSDL (Web Service Description Language), and UDDI (Universal Description, Discovery, and Integration protocol). It covers the concepts of the Web services architecture and offers practical advice on building and deploying Web services in the enterprise. It decodes the standards, explaining the concepts and implementation in a clear, concise style. You'll also learn about the major toolkits for building and deploying Web services. Examples in Java, Perl, C#, and Visual Basic illustrate the principles. Significant applications developed using Java and Perl on the Apache Tomcat Web platform address real issues such as security, debugging, and interoperability.

Geometry, of all the branches of mathematics, is the one that is most easily visualized by making something. However, it is all too easy to reduce it to reams of formulas to memorize and proofs to replicate. This book aims to take geometry back to its practical roots with 3D printed models and puzzles as well as demonstrations with household objects like flashlights and paper towel tubes. This is not a traditional geometry textbook, but rather builds up understanding of geometry concepts while also bringing in elements of concepts normally learned much later. Some of the models are counterintuitive, and figuring out how and why they work will both entertain and give insights. Two final chapters suggesting open-ended projects in astronomy and physics, and art and architecture, allow for deeper understanding and integration of the learning in the rest of the book.

There are lots of introductory C books, but this is the first one that has the no-nonsense, practical approach that has made Nutshell Handbooks(r) famous. C programming is more than just getting the syntax right. Style and debugging also play a tremendous part in creating programs that run well and are easy to maintain. This book teaches you not only the mechanics of programming, but also describes how to create programs that are easy to read, debug, and update. Practical rules are stressed. For example, there are fifteen precedence rules in C (&& comes before || comes before ?:). The practical programmer reduces these to two: * Multiplication and division come before addition and subtraction. Contrary to popular belief, most programmers do not spend most of their time creating code. Most of their time is spent modifying someone else's code. This books shows you how to avoid the all-too-common obfuscated uses of C (and also to recognize these uses when you encounter them in existing programs) and thereby to leave code that the programmer responsible for maintenance does not have to struggle with. Electronic Archaeology, the art of going through someone else's code, is described. This third edition introduces popular Integrated Development Environments on Windows systems, as well as UNIX programming utilities, and features a large statistics-generating program to pull together the concepts and features in the language.
