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.

    Johnson. It was the first book exclusively on the theory of NP-completeness and computational intractability. The book features an appendix providing a thorough compendium of NP-complete problems (which was updated in later printings of the book). The book is now outdated in some respects as it does not cover more recent development such as the PCP theorem. It is nevertheless still in print and is regarded as a classic: in a 2006 study, the CiteSeer search engine listed the book as the most cited reference in computer science literature.

    Sipser's candid, crystal-clear style allows students at every level to understand and enjoy this field. His innovative "proof idea" sections explain profound concepts in plain English. The new edition incorporates many improvements students and professors have suggested over the years, and offers updated, classroom-tested problem sets at the end of each chapter.

    So successful was he that in 1966 Rolls-Royce decided the best thing to do was to spend 63.6 million pounds and buy its rival. By this time there was scarcely a single modern British aero-engine for which Hooker had not been responsible.

    The newest screenplay from the Oscar®-nominated writers of Election and About Schmidt, Sideways is the tale of two men's adventure in California wine country.Based on Rex Pickett's acclaimed first novel, Sideways tells the story of Miles (Paul Giamatti), a failed novelist, and his soon-to-be-married friend Jack (Thomas Haden Church), a washed-up actor.To salute the remains of their youth, the two men take one last road trip in the week before Jack's wedding.A serious wine enthusiast, Miles is determined to educate his friend on the region's beloved Pinot Noir wines before the week is out.Jack indulges his best friend's passion for the grape but is mainly interested in living his last week of bachelorhood to the hilt.Trouble ensues with wine and women (Virginia Madsen and Sandra Oh), and the duo comes to some profound realizations as they come to terms with maturity.

    It follows standards-based principles, but also teaches readers ways around problems they are likely to face using (X)HTML.While XHTML is the "current" standard, the book still covers HTML because many people do not yet understand that XHTML is the official successor to HTML, and many readers will still stick with HTML for backward compatibility and simpler/informal Web pages that don't require XHTML compliance.The book teaches basic principles of usability and accessibility along the way, to get users into the mode of developing Web pages that will be available to as many viewers as possible from the start. The book also covers the most commonly used programming/scripting language -- JavaScript -- and provides readers with a roadmap of other Web technologies to learn after mastering this book to add more functionality to their sites.

    To professional players, it is the hardest part in practice, as well; in championship games that last two days, for instance, the first day is usually spent playing and thinking about the first 50 moves, and the second day is spent finishing all the rest. Such is the consistency of professional play in the middle game and endgame that if a player comes out of the opening with a bad position, it is almost impossible for him to catch up. Amateurs sometimes rush through their initial moves, saving their powers for the fighting later, but this is more an indication that they do not understand the opening than a sign of talent. The number of possibilities in any opening position is so vast that a player must rely on his feeling for the game rather than on rigorous analysis for guidance. Here he has the greatest chance to use his imagination, play creatively, and develop a personal style. This is the one phase of go that has shown any significant evolution during the past few centuries, and it still defies absolute comprehension. No book can develop a person's imagination or personal style, and this one does not make the attempt. In a sense, therefore, it is very incomplete: the reader will not find a prescription for every situation and in actual play he will have to make his own choices most of the time. What we have tried to give him is a basis to start from: some sound moves, some useful ideas, some good examples. If we have succeeded, the following pages will help him to increase both his skill at and enjoyment of the game.

    This second edition is appropriate as a supplementary (companion) text for any college-level course covering digital signal processing.

    Mastering this art will not only make you the most desired developer in the market, but it will transform the craziest deadline into "Consider it done, Sir".

    Building on the successful top-down approach of previous editions, this fourth edition continues with an early emphasis on application-layer paradigms and application programming interfaces, encouraging a hands-on experience with protocols and networking concepts.

    It should be labelled 'start here'." --Pieter Jan Stappers, ID-StudioLab, Delft University of Technology

    Python is considered easy to learn, but there's no quicker way to mastery of the language than learning from an expert teacher. This edition of "Learning Python" puts you in the hands of two expert teachers, Mark Lutz and David Ascher, whose friendly, well-structured prose has guided many a programmer to proficiency with the language. "Learning Python," Second Edition, offers programmers a comprehensive learning tool for Python and object-oriented programming. Thoroughly updated for the numerous language and class presentation changes that have taken place since the release of the first edition in 1999, this guide introduces the basic elements of the latest release of Python 2.3 and covers new features, such as list comprehensions, nested scopes, and iterators/generators. Beyond language features, this edition of "Learning Python" also includes new context for less-experienced programmers, including fresh overviews of object-oriented programming and dynamic typing, new discussions of program launch and configuration options, new coverage of documentation sources, and more. There are also new use cases throughout to make the application of language features more concrete. The first part of "Learning Python" gives programmers all the information they'll need to understand and construct programs in the Python language, including types, operators, statements, classes, functions, modules and exceptions. The authors then present more advanced material, showing how Python performs common tasks by offering real applications and the libraries available for those applications. Each chapter ends with a series of exercises that will test your Python skills and measure your understanding."Learning Python," Second Edition is a self-paced book that allows readers to focus on the core Python language in depth. As you work through the book, you'll gain a deep and complete understanding of the Python language that will help you to understand the larger application-level examples that you'll encounter on your own. If you're interested in learning Python--and want to do so quickly and efficiently--then "Learning Python," Second Edition is your best choice.

    Their discussion ranges from the history of the field's intellectual foundations to the most recent developments and applications.Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives when interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the key ideas and algorithms of reinforcement learning. Their discussion ranges from the history of the field's intellectual foundations to the most recent developments and applications. The only necessary mathematical background is familiarity with elementary concepts of probability.The book is divided into three parts. Part I defines the reinforcement learning problem in terms of Markov decision processes. Part II provides basic solution methods: dynamic programming, Monte Carlo methods, and temporal-difference learning. Part III presents a unified view of the solution methods and incorporates artificial neural networks, eligibility traces, and planning; the two final chapters present case studies and consider the future of reinforcement learning.
