    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.

    He was a normal kid...On February 7, 2000, Yahoo.com was the first victim of the biggest distributed denial-of-service attack ever to hit the Internet. On May 8th, Buy.com was battling a massive denial-of-service attack. Later that afternoon, eBay.com also reported significant outages of service, as did Amazon.com. Then CNN's global online news operation started to grind to a crawl. By the following day, Datek and E-Trade entered crisis mode...all thanks to an ordinary fourteen-year-old kid.Friends and neighbors were shocked to learn that the skinny, dark-haired, boy next door who loved playing basketball--almost as much as he loved computers--would cause millions of dollars worth of damage on the Internet and capture the attention of the online world--and the federal government. He was known online as Mafiaboy and, to the FBI, as the most notorious teenage hacker of all time. He did it all from his bedroom PC. And he's not alone.Computer hacking and Web site defacement has become a national pastime for America's teenagers, and according to the stories you'll read about in The Hacker Diaries--it is only the beginning. But who exactly are these kids and what motivates a hacker to strike? Why do average teenagers get involved in hacking in the first place? This compelling and revealing book sets out to answer these questions--and some of the answers will surprise you. Through fascinating interviews with FBI agents, criminal psychologists, law-enforcement officials--as well as current and former hackers--you'll get a glimpse inside the mind of today's teenage hacker. Learn how they think, find out what it was like for them growing up, and understand the internal and external pressures that pushed them deeper and deeper into the hacker underground. Every hacker has a life and story of his or her own. One teenager's insatiable curiosity as to how the family's VCR worked was enough to trigger a career of cracking into computer systems. This is a remarkable story of technological wizardry, creativity, dedication, youthful angst, frustration and disconnection from society, boredom, anger, and jail time. Teenage hackers are not all indifferent punks. They're just like every other kid and some of them probably live in your neighborhood. They're there. All you have to do is look.

    "Design Patterns Explained "complements the existing design patterns texts and may perform a very useful role, fitting between introductory texts such as UML Distilled and the more advanced patterns books." James Noble Leverage the quality and productivity benefits of patterns without the complexity! "Design Patterns Explained, Second Edition" is the field's simplest, clearest, most practical introduction to patterns. Using dozens of updated Java examples, it shows programmers and architects exactly how to use patterns to design, develop, and deliver software far more effectively. You'll start with a complete overview of the fundamental principles of patterns, and the role of object-oriented analysis and design in contemporary software development. Then, using easy-to-understand sample code, Alan Shalloway and James Trott illuminate dozens of today's most useful patterns: their underlying concepts, advantages, tradeoffs, implementation techniques, and pitfalls to avoid. Many patterns are accompanied by UML diagrams. Building on their best-selling First Edition, Shalloway and Trott have thoroughly updated this book to reflect new software design trends, patterns, and implementation techniques. Reflecting extensive reader feedback, they have deepened and clarified coverage throughout, and reorganized content for even greater ease of understanding. New and revamped coverage in this edition includesBetter ways to start "thinking in patterns"How design patterns can facilitate agile development using eXtreme Programming and other methodsHow to use commonality and variability analysis to design application architecturesThe key role of testing into a patterns-driven development processHow to use factories to instantiate and manage objects more effectivelyThe Object-Pool Pattern a new pattern not identified by the "Gang of Four"New study/practice questions at the end of every chapter Gentle yet thorough, this book assumes no patterns experience whatsoever. It's the ideal "first book" on patterns, and a perfect complement to Gamma's classic "Design Patterns." If you're a programmer or architect who wants the clearest possible understanding of design patterns or if you've struggled to make them work for you read this book.

    Since that time, this text has been revised, tweaked, and enhanced to account for the changes found within each release of the .NET platform (1.1, 2.0, 3.0 and now 3.5)..NET 3.0 was more of an augmentative release, essentially providing three new APIs: Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF). As you would expect, coverage of the "W's" has been expanded a great deal in this version of the book from the previous Special Edition text.Unlike .NET 3.0, .NET 3.5 provides dozens of C# language features and .NET APIs. This edition of the book will walk you through all of this material using the same readable approach as was found in previous editions. Rest assured, you'll find detailed coverage of Language Integrated Query (LINQ), the C# 2008 language changes (automatic properties, extension methods, anonymous types, etc.) and the numerous bells and whistles of Visual Studio 2008. What you'll learn Everything you need to knowget up to speed with C# 2008 quickly and efficiently. Discover all the new .NET 3.5 featuresLanguage Integrated Query, anonymous types, extension methods, automatic properties, and more.
