         Ronan O'Gara has been at the heart of Munster and Irish rugby for the past fifteen years. Now, as he comes to the end of a glittering playing career, it is time for him to reflect on those many successes and occasional failures with the straight-talking attitude that has become his trademark. Never one to shy away from the truth, the result is Ronan O'Gara: Unguarded.     Packed full of anecdotes and analysis of the teammates O'Gara has been proud to share the shirt with, and of the coaches he has played under -- often in controversial circumstances -- this is the definitive record of an era when Munster rose to triumph in Europe, and Ireland to win the Grand Slam, before crashing down to earth again. It is simply the must-have rugby book of the year.

    As an important contributor to the online documentation for MySQL, Paul uses his day-to-day experience answering questions users post on the MySQL mailing list to pinpoint the problems most users and administrators encounter. The principal MySQL developer, Monty Widenius, along with a network of his fellow developers, reviewed the manuscript, providing Paul with the kind of insight no one else could supply. Instead of merely giving you a general overview of MySQL, Paul teaches you how to make the most of its capabilities. Through two sample databases that run throughout the book, he gives you solutions to problems you'll likely face. He helps you integrate MySQL efficiently with third-party tools, such as PHP and Perl, enabling you to generate dynamic Web pages through database queries. He also teaches you to write programs that access MySQL databases.

    The author successfully introduces Maxwell's equations, wave propagation, network analysis, and design principles as applied to modern microwave engineering. A considerable amount of material in this book is related to the design of specific microwave circuits and components, for both practical and motivational value. It also presents the analysis and logic behind these designs so that the reader can see and understand the process of applying the fundamental concepts to arrive at useful results. The derivations are well laid out and the majority of each chapter's formulas are displayed in a nice tabular format every few pages. This Third Edition offers greatly expanded coverage with new material on: Noise; Nonlinear effects; RF MEMs; transistor power amplifiers; FET mixers; oscillator phase noise; transistor oscillators and frequency multiplier.

    When Ruby first burst onto the scene in the Western world, the Pragmatic Programmers were there with the definitive reference manual, Programming Ruby: The Pragmatic Programmer's Guide.Now in its second edition, author Dave Thomas has expanded the famous Pickaxe book with over 200 pages of new content, covering all the improved language features of Ruby 1.8 and standard library modules. The Pickaxe contains four major sections:An acclaimed tutorial on using Ruby.The definitive reference to the language.Complete documentation on all built-in classes, modules, and methodsComplete descriptions of all 98 standard libraries.If you enjoyed the First Edition, you'll appreciate the expanded content, including enhanced coverage of installation, packaging, documenting Ruby source code, threading and synchronization, and enhancing Ruby's capabilities using C-language extensions. Programming for the World Wide Web is easy in Ruby, with new chapters on XML/RPC, SOAP, distributed Ruby, templating systems, and other web services. There's even a new chapter on unit testing.This is the definitive reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including more than 250 significant changes since the First Edition). Coverage of other features has grown tremendously, including details on how to harness the sophisticated capabilities of irb, so you can dynamically examine and experiment with your running code. Ruby is a wonderfully powerful and useful language, and whenever I'm working with it this book is at my side --Martin Fowler, Chief Scientist, ThoughtWorks

    Divided into two parts, the first part of the book introduces the programming language Prolog, while the second part teaches Artificial Intelligence using Prolog as a tool for the implementation of AI techniques. Prolog has its roots in logic, however the main aim of this book is to teach Prolog as a practical programming tool. This text therefore concentrates on the art of using the basic mechanisms of Prolog to solve interesting problems. The third edition has been fully revised and extended to provide an even greater range of applications, which further enhance its value as a self-contained guide to Prolog, AI or AI Programming for students and professional programmers alike.

    It's used to create and maintain database objects, place data into those objects, query the data, modify the data, and, finally, delete data that is no longer needed. Databases lie at the heart of many, if not most business applications. Chances are very good that if you're involved with software development, you're using SQL to some degree. And if you're using SQL, you should own a good reference or two.Now available in an updated second edition, our very popular "SQL Pocket Guide" is a major help to programmers, database administrators, and everyone who uses SQL in their day-to-day work. The "SQL Pocket Guide" is a concise reference to frequently used SQL statements and commonly used SQL functions. Not just an endless collection of syntax diagrams, this portable guide addresses the language's complexity head on and leads by example. The information in this edition has been updated to reflect the latest versions of the most commonly used SQL variants including: Oracle Database 10g, Release 2 (includingthe free Oracle Database 10g Express Edition (XE))Microsoft SQL Server 2005MySQL 5IBM DB2 8.2PostreSQL 8.1 database

    Captain Shore’s enthusiasm for firearms and especially for rifles led him to take every possible opportunity to try out different weapons, ammunition and methods of shooting. His interest was combined with sound common sense, and he would never countenance a rumour about a particular weapon or incident unless he was able to confirm it for himself.As a result everything in this book is based on his personal experience. In World War II Captain Shore took part in the British landings at D-Day, and fought in Normandy and northern Europe. He came across many different weapons in varying condition, some of the worst being those used by the Dutch and Belgian resistance fighters. He was keen to learn from experienced snipers and then to train others, and he became an officer sniping instructor at the British Army of the Rhine Training Centre.He shares a wealth of first-hand knowledge of different rifles, pistols, machine guns, ammunition, telescopes, binoculars and all the equipment a sniper should carry. This is not only an account of sniping in World War II but also a guide to all aspects of sniping based on personal knowledge and experience in training and battle. Illustrated heavily with photos, pictures and other illustrations of snipers, their weapons and their tactics.

    This text is user-focused and has been highly updated including topics, pictures and examples. The Williams text contains less theory and more application to engage students who might be more familiar with technology. Continually published and updated for over 15 years, Using Information Technology was the first text to foresee and define the impact of digital convergence--the fusion of computers and communications. It was also the first text to acknowledge the new priorities imposed by the Internet and World Wide Web and bring discussion of them from late in the course to the beginning. Today, it is directed toward the "Always On" generation that is at ease with digital technology--comfortable with iPhones, MySpace, Facebook, Twitter, Wikipedia, and the blogosphere--but not always savvy about its processes, possibilities, and liabilities. This 8th edition continues to address the two most significant challenges that instructors face in teaching this course: -Trying to make the course interesting and challenging, and -Trying to teach to students with a variety of computer backgrounds. In addition, this text correlates with Simnet Online for full integration of resources within the Computing Concepts course.
