    He is a brilliant kicker both from the hand and at penalty goals, a sublime organizer of play from the out-half position, and a cool head in the pressure-cooker of club and international rugby. The list of the Cork man's achievements goes on and on:  he is the leading points scorer in Irish rugby history, and one of the top ten in the world; the leading points scorer in the history of the Heineken Cup; and the first ever points and try scorer at the home of Gaelic sports, Croke Park. In his candid, illuminating autobiography, O'Gara tells the story of those many on-field successes, culminating in the glorious year of 2006 when his tactical prowess and will to win first helped guide Ireland to the Triple Crown in the Six Nations championship, then Munster to a memorable Heineken Cup victory over Biarritz at the Millennium Stadium in Cardiff. O'Gara kicked a perfect five out of five in the 23-19 win as Munster lifted the coveted trophy for the first time, sparking wild celebrations heard all the way back in Limerick and Cork. Yet as in any sporting career, there have been the setbacks as well, most notably Ireland's disappointing performance in the Rugby World Cup in France last year. O'Gara reveals what really went on in a divided dressing-room as a series of flat performances sent the Irish crashing out, while he personally had to deal with a series of front-page allegations about his private life. O’Gara has never been shy about the fact that he's fond of a drink and a bet, and he confronts his critics head on in this book. This is the unforgettable story of a rugby player at the top of his game, of a life lived to the full, and of a passionate and proud representative of the people of Cork and Ireland.

    But, although they use these patterns purposefully, they often use them informally and nearly unconsciously. This book organizes this substantial emerging "folklore" of system design -- with its rich language of system description -- and closes the gap between the useful abstractions (constructs and patterns) of system design and the current models, notations and tools. It identifies useful patterns clearly, gives examples, compares them, and evaluates their utility in various settings -- allowing readers to develop a repertoire of useful techniques that goes beyond the single-minded current fads. KEY TOPICS: Examines the ways in which architectural issues can impact software design; shows how to design new systems in principled ways using well-understood architectural paradigms; emphasizes informal descriptions, touching lightly on formal notations and specifications, and the tools that support them; explains how to understand and evaluate the design of existing software systems from an architectural perspective; and presents concrete examples of actual system architectures that can serve as models for new designs. MARKET: For professional software developers looking for new ideas about system organization.
