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

    He seemed pointed toward stardom, but would it be in basketball, his true favorite, or maybe in track, where he qualified for the 2008 U.S. Olympic Trials as a hurdler? As for playing football, the only sport that really mattered in Griffin’s small Texas town, first he had to overcome his mother’s objections to the violence and danger—which he did by making a “Pinkie Promise” with her that no one would catch him. Eventually, he began to realize that all of his remarkable talents—unrivaled speed, pinpoint accuracy, exceptional intelligence, single-minded drive—combined into a potent force that few quarterbacks could rival. What followed seemed almost destined: a football scholarship to Baylor University, three exceptional seasons capped by winning the Heisman Trophy, and the 2012 draft—where Griffin, as the second overall pick, became the franchise quarterback for one of the oldest and most storied football teams in the country.In RG3: The Promise, Washington Post reporter Dave Sheinin provides an in-depth, behind-the-scenes look at Griffin’s first year in the NFL, from his record-breaking first game to the frightening knee injury that ended the Redskins’ playoff hopes. An award-winning journalist himself, Sheinin has reported on Griffin’s rookie season every step of the way, and now has written a unique, intimate look inside the transformation of one of the NFL’s brightest young stars.

    In Domain-Specific Languages , noted software development expert Martin Fowler first provides the information software professionals need to decide if and when to utilize DSLs. Then, where DSLs prove suitable, Fowler presents effective techniques for building them, and guides software engineers in choosing the right approaches for their applications. This book's techniques may be utilized with most modern object-oriented languages; the author provides numerous examples in Java and C#, as well as selected examples in Ruby. Wherever possible, chapters are organized to be self-standing, and most reference topics are presented in a familiar patterns format. Armed with this wide-ranging book, developers will have the knowledge they need to make important decisions about DSLs--and, where appropriate, gain the significant technical and business benefits they offer. The topics covered include: - How DSLs compare to frameworks and libraries, and when those alternatives are sufficient - Using parsers and parser generators, and parsing external DSLs - Understanding, comparing, and choosing DSL language constructs - Determining whether to use code generation, and comparing code generation strategies - Previewing new language workbench tools for creating DSLs

    The chilling words are followed by a confession to a murder committed nearly 13 years earlier.

If that's what you want to do, that is. Maybe you don't care about the exam, but need to use Servlets & JSPs in your next project. You're working on a deadline. You're over the legal limit for caffeine. You can't waste your time with a book that makes sense only AFTER you're an expert (or worse one that puts you to sleep). No problem. Head First Servlets and JSP's brain-friendly approach drives the knowledge straight into your head (without sharp instruments). You'll interact with servlets and JSPs in ways that help you learn quickly and deeply. It may not be The Da Vinci Code, but quickly see why so many reviewers call it "a page turner". Most importantly, this book will help you use what you learn. It won't get you through the exam only to have you forget everything the next day. Learn to write servlets and JSPs, what makes the Container tick (and what ticks it off), how to use the new JSP Expression Language (EL), what you should NOT write in a JSP, how to write deployment descriptors, secure applications, and even use some server-side design patterns.

    AND TO KILL All his life Greg McPartlin wanted to be a Marine corpsman, a medic skilled at saving lives. Three months of bagging-and-tagging bodies during Vietnam s Tet Offensive took the luster off of being a Marine but not off McPartlin’s desire to serve his country. After assisting in the sea recovery of Apollo 11 the first ship to bring men to the moon the twenty-year-old McPartlin was redeployed to Vietnam as an elite Navy SEAL. Barred as a medic from the make-or-break training of BUD/S considered vital to service as a Navy SEAL, McPartlin had to show he had what it took. But McPartlin had been in country before. In a war where you partied with your buddies in Saigon one day and crawled through an enemy-infested jungle hell the next, he proved that he was not only an outstanding medic but a real Navy SEAL the toughest of the tough. Combat Corpsman is McPartlin’s often humorous—and terrifying—account of his year of combat in what had been a Viet Cong stronghold until the SEALs took control and Charlie placed bounties on the men with green faces. It is the first inside story of a Navy SEAL medic, a man who wanted to heal, not to kill, but did both to save lives. This edition is heavily illustrated with 100 historical and personal photographs from Greg McPartlin’s tour of duty in Vietnam. Editorial Reviews: I wish I could make up anything as riotously wonderful yet starkly realistic as this book. —H. Jay Riker, author of The Silent Service: Virginia Class An accurate and humorous account of an early Navy SEAL platoon in Vietnam. —Frank Thornton, the most decorated SEAL from Vietnam era You would be hard-pressed to find a more gritty, realistic, tale of the rigors of combat and the actions of a SEAL Corpsman. The action on these pages is so real you can smell the mud, feel the sweetish taste of the powder smoke in the back of your mouth, hear the fragments whiz by and the bullets snap past - and know in a small way just what it is like to be one of the best. —Kevin Dockery, author of Hunters and Shooters and The Complete History of the Navy SEALs

    The unit, the reports claimed, had carried out a series of illegal spook operations: they had spied on President Jacob Zuma, run a brothel, illegally bought spyware and entered into unlawful tax settlements.In a plot of Machiavellian proportions, head of the elite crime-busting unit Johann van Loggerenberg and many of SARS’s top management were forced to resign.
