Today, Rails developers and architects need better ways to interface with legacy systems, move into the cloud, and scale to handle higher volumes and greater complexity. In Service-Oriented Design with Ruby and Rails Paul Dix introduces a powerful, services-based design approach geared toward overcoming all these challenges. Using Dix's techniques, readers can leverage the full benefits of both Ruby and Rails, while overcoming the difficulties of working with larger codebases and teams. Dix demonstrates how to integrate multiple components within an enterprise application stack; create services that can easily grow and connect; and design systems that are easier to maintain and upgrade. Key concepts are explained with detailed Ruby code built using open source libraries such as ActiveRecord, Sinatra, Nokogiri, and Typhoeus. The book concludes with coverage of security, scaling, messaging, and interfacing with third-party services. Service-Oriented Design with Ruby and Rails will help you Build highly scalable, Ruby-based service architectures that operate smoothly in the cloud or with legacy systems Scale Rails systems to handle more requests, larger development teams, and more complex code bases Master new best practices for designing and creating services in Ruby Use Ruby to glue together services written in any language Use Ruby libraries to build and consume RESTful Web services Use Ruby JSON parsers to quickly represent resources from HTTP services Write lightweight, well-designed API wrappers around internal or external services Discover powerful non-Rails frameworks that simplify Ruby service implementation Implement standards-based enterprise messaging with Advanced Message Queuing Protocol (AMQP) Optimize performance with load balancing and caching Provide for security and authentication

    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.
