This book is not a typical O'Reilly book, written as a cohesive manuscript by one or two authors. Instead, it is a new kind of book a first, bold attempt at applying some principles of open source development to book authoring. About 200 members of the Python community contributed recipes to this book. In this Preface, we, the editors, want to give you, the reader, some background regarding how this book came about and the processes and people involved, and some thoughts about the implications of this new form.

Programming .NET Components, Second Edition begins with a look at the fundamentals of component-oriented programming and then progresses from there. It takes the time to carefully examine how components can simplify and add flexibility to complex applications by allowing users to extend their capabilities. Next, the book introduces a variety of .NET essentials, as well as .NET development techniques. Within this discussion on component development, a separate chapter is devoted to each critical development feature, including asynchronous calls, serialization, remoting, security, and more. All the while, hazardous programming pitfalls are pointed out, saving the reader from experiencing them the hard way.

Perl is a very powerful tool for Oracle database administrators, but too few DBAs realize how helpful Perl can be in managing, monitoring, and tuning Oracle9i, Oracle8i, and earlier databases. You don't need to be a Perl expert to reap the rewards of reading Perl for Oracle DBAs. The book explains what you need to know about Perl, profiles the best Perl open source applications available to DBAs, and provides the Perl DBA Toolkit, a comprehensive suite of ready-to-use scripts designed to ease the burden of Oracle database administration.

This book has two goals: to make you a Perl expert, and, at a broader level, to supplement your current
arsenal of techniques and tools for crafting applications. It covers advanced features of the Perl language,
teaches you how the perl interpreter works, and presents areas of modern computing technology such as
networking, user interfaces, persistence, and code generation.

This book is about the Java™ language and programming environment. If you've been at all active on the Internet in the past few years, you've heard a lot about Java. It's one of the most exciting developments in the history of the Internet, rivaling the creation of the World Wide Web. Java became the darling of the Internet programming community as soon as the alpha version was released. Immediately, thousands of people were writing Java applets to add to their web pages. Interest in Java only grew with time, and support for Java in Netscape Navigator guaranteed it would be a permanent part of the Net scene.

This book is intended for everyone who has a UNIX computer connected to a TCP/IP network. This obviously includes the network managers and the system administrators who are responsible for setting up and running computers and networks, but it also includes any user who wants to understand how his or her computer communicates with other systems. The distinction between a "system administrator" and an "end user" is a fuzzy one. You may think of yourself as an end user, but if you have a UNIX workstation on your desk, you're probably also involved in system administration tasks.

This book covers all the built-in features and standard bundled libraries of Ruby. It isn't an introductory book; rather it works best sitting top of your desk when you program in Ruby. The book assumes you have prior programming experience, preferably in Ruby. System programming experience may be required to understand some parts of the book, for example, network programming using sockets.

Director in a Nutshell is the most concise and complete guide available for Director. It also covers the use of Director on the Internet with Shockwave, Netscape Navigator, and Microsoft Internet Explorer. Java in a Nutshell and WebMaster in a Nutshell have established themselves as indispensable developer references, and Director in a Nutshell continues this family tradition. Like all In a Nutshell books, it takes the Director topic and drills down, expands, and delights the reader by providing useful information that the reader didn't even expect to find.

Steven Feuerstein's first book, Oracle PR/SQL Programming, has become an indispensable reference for both novice and experienced PL/SQL developers. This new book focuses on one particularly important and advanced aspect of Oracle's powerful PL/SQL language -- the built-in packages. Built-in packages are collections of PL/SQL objects stored directly in the Oracle database and available from such programming environments as Visual Basic, Oracle Developer/2000, Oracle application server (for web-based development), and, of course, the Oracle database itself. Built-in packages dramatically extend the capabilities of PL/SQL. For example, DBMS_SQL executes dynamically constructed SQL statements and PL/SQL blocks of code; DBMS_PIPE communicates between different Oracle sessions; and DBMS_LOB accesses and manipulates Oracle8's large objects (LOBs) from within PL/SQL programs. Oracle Built-in Packages is the first and only comprehensive reference to the Oracle built-in packages. It supplies extensive examples on using the built-ins effectively and covers the newest Oracle8 packages. The book comes with a diskette containing the companion guide, an online tool developed by RevealNet, Inc., that provides point-and-click access to more than 175 files of reusable source code and examples.

The first edition of Oracle PL/SQL Programming quickly became an indispensable reference for both novice and experienced PL/SQL developers. Oracle8 presents PL/SQL programmers with new challenges by increasing both the possibilities and complexities of the language. This second edition focuses on Oracle8, covering Oracle8 object types, collections, object views, and external procedures. It also contains a chapter on tuning PL/SQL, as well as expanded discussions of debugging and tracing PL/SQL execution. A companion diskette contains the Companion Utilities Guide for Oracle PL/SQL Programming, an online Windows-based tool that includes more than 100 files of source code and documentation prepared by the authors. Experienced developers will learn even more about this powerful language, and newcomers to PL/SQL will soon be on the road to mastery.

This tutorial for Perl/Tk, the extension to Perl for creating graphical user interfaces, shows how to use Perl/Tk to build graphical, event-driven applications for both Windows and UNIX. With Tk, Perl programs can be window-based rather than command-line based, with buttons, entry fields, listboxes, menus, and scrollbars. Anyone who has written even the simplest Perl program should be able to learn Tk from this book. It gets right to the point of what you need to know and why, teaching how to implement and configure each Perl/Tk graphical element. Numerous illustrations demonstrate how each element is drawn and how its configuration options affect its presentation. Learning Perl/Tk is for every Perl programmer who would like to implement simple, easy-to-use graphical interfaces.

Programming Perl, 2nd Edition is the authoritative guide to Perl version 5, the scripting utility that has established itself as the programming tool of choice for the World Wide Web, UNIX system administration, and a vast range of other applications. Version 5 of Perl includes object-oriented programming facilities. The book is coauthored by Larry Wall, the creator of Perl.

This book is a quick-reference guide for Recovery Manager (RMAN), Oracle's utility to manage all of your Oracle database backup and recovery activities. This book is not a comprehensive backup and recovery book. It contains an overview of RMAN architecture, shows briefly how to backup and restore databases using RMAN, describes catalog setup issues, and provides quick-reference syntax diagrams of RMAN commands.

It takes a book as versatile as its subject to cover Apache Tomcat, the popular open source Servlet and JSP container and high performance web server. Tomcat: The Definitive Guide is a valuable reference for administrators and webmasters, a useful guide for programmers who want to use Tomcat as their web application server during development or in production, and an excellent introduction for anyone interested in Tomcat.
