Do you want to push Ruby to its limits? The Ruby Cookbook is the most comprehensive problem-solving guide to today's hottest programming language. It gives you hundreds of solutions to real-world problems, with clear explanations and thousands of lines of code you can use in your own projects.

From data structures and algorithms, to integration with cutting-edge technologies, the Ruby Cookbook has something for every programmer. Beginners and advanced Rubyists alike will learn how to program with:

• Strings and numbers
• Arrays and hashes
• Classes, modules, and namespaces
• Reflection and metaprogramming
• XML and HTML processing
• Ruby on Rails (including Ajax integration)
• Databases
• Graphics
• Internet services like email, SSH, and BitTorrent
• Web services
• Multitasking
• Graphical and terminal interfaces

If you need to write a web application, this book shows you how to get started with Rails. If you're a system administrator who needs to rename thousands of files, you'll see how to use Ruby for this and other everyday tasks. You'll learn how to read and write Excel spreadsheets, classify text with Bayesian filters, and create PDF files. We've even included a few silly tricks that were too cool to leave out, like how to blink the lights on your keyboard.

The Ruby Cookbook is the most useful book yet written about Ruby. When you need to solve a problem, don't reinvent the wheel: look it up in the Cookbook.

Nothing is as constant as change, and this is as true in enterprise computing as anywhere else. With the recent release of Java 2 Enterprise Edition 1.4, developers are being called on to add even greater, more complex levels of interconnectivity to their applications.

To do this, Java developers today need a clear understanding of how to apply the new APIs, use the latest open source Java tools, and learn the capabilities and pitfalls in Java 2 Enterprise Edition 1.4 -- so they can plan a technology and implementation strategy for new enterprise projects.

Fortunately, this is exactly what they get with the new Java Enterprise in a Nutshell, 3rd Edition. Because most integrated development environments (IDE) today include API lookup, we took out the main API sections from our previous edition to make room for new chapters, among others, on Ant, Cactus, Hibernate, Jakarta Struts, JUnit, security, XDoclet, and XML/JAXP.

Revised and updated for the new 1.4 version of Sun Microsystems Java Enterprise Edition software, Java Enterprise in a Nutshell, 3rd Edition is a practical guide for enterprise Java developers.

In the last few years, security has become a hot-button issue for IT organizations of all sizes. Accordingly, many of the security features that were either optional or suspect in Windows 2000 have become solid, effective fixtures in Windows Server 2003-making it the most secure operating system Microsoft has ever produced. That is, if you know how to configure it properly.

The Windows Server 2003 Security Cookbook wants to make sure that you do know how. Picking up right where its predecessor, the Windows Server Cookbook, left off, this desktop companion is focused solely on Windows Server security. It teaches you how to perform important security tasks in the Windows Server 2003 OS using specific and adaptable recipes. Each recipe features a brief description of the problem, a step-by-step solution, and then a discussion of the technology at work. Whenever possible, the authors even tell you where to look for further information on a recipe.

The book is written in a highly modular format, with each chapter devoted to one or more technologies that Windows Server 2003 provides. This approach allows you to look up a task or scenario that you want to accomplish, find that page, and read that particular recipe only. Topics include:

• System preparation and administration
• Protecting the computer at the TCP/IP level
• Applying security options to Active Directory
• Improving security on domain controllers
• Securing DHCP controllers
• Encrypting and signing network traffic using IPSec
• Patch management

If you're an intermediate or advanced system administrator who wants to feel secure when deploying Windows Server 2003 and its related services, then you don't want to be without the Windows Server 2003 Security Cookbook.

System developers have used modeling languages for decades to specify, visualize, construct, and document systems. The Unified Modeling Language (UML) is one of those languages. UML makes it possible for team members to collaborate by providing a common language that applies to a multitude of different systems. Essentially, it enables you to communicate solutions in a consistent, tool-supported language.

Today, UML has become the standard method for modeling software systems, which means you're probably confronting this rich and expressive language more than ever before. And even though you may not write UML diagrams yourself, you'll still need to interpret diagrams written by others.

UML 2.0 in a Nutshell from O'Reilly feels your pain. It's been crafted for professionals like you who must read, create, and understand system artifacts expressed using UML. Furthermore, it's been fully revised to cover version 2.0 of the language.

This comprehensive new edition not only provides a quick-reference to all UML 2.0 diagram types, it also explains key concepts in a way that appeals to readers already familiar with UML or object-oriented programming concepts.

Topics include:

• The role and value of UML in projects
• The object-oriented paradigm and its relation to the UML
• An integrated approach to UML diagrams
• Class and Object, Use Case, Sequence, Collaboration, Statechart, Activity, Component, and Deployment Diagrams
• Extension Mechanisms
• The Object Constraint Language (OCL)

If you're new to UML, a tutorial with realistic examples has even been included to help you quickly familiarize yourself with the system.

You know the rudiments of the SQL query language, yet you feel you aren't taking full advantage of SQL's expressive power. You'd like to learn how to do more work with SQL inside the database before pushing data across the network to your applications. You'd like to take your SQL skills to the next level.

Let's face it, SQL is a deceptively simple language to learn, and many database developers never go far beyond the simple statement: SELECT FROM
