By applying the design patterns outlined in this book, you’ll learn how to write flexible and resilient code that’s easier—not harder—to work with as your code base grows.JavaScript has become one of the most widely used—and essential—programming languages for the Web, on both the client-side and server-side. In the real world, JavaScript applications are fragile, and when you change them things often break. Author Eric Elliott shows you how to add features without creating bugs or negatively impacting the rest of your code during the course of building a large JavaScript application.Examine the anatomy of a modern JavaScript applicationLearn best practices for code organization, modularity, and reuseApply Model-View-Controller architectures to client-side web developmentDelve into client-side (browser) and server-side (Node) approachesUse Node to design and program RESTful APIsLearn the processes teams use to build, test, deploy, and scale large JavaScript applicationsExpand your application’s reach through platform targets and internationalization

    The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

    Relentlessly practical, the book delivers insight, not documentation, to teach developers what they need to know to build the next generation of SOAs.After explaining the advantages of service-orientation for application design and teaching the basics of how to develop SOAs using WCF, the book shows how you can take advantage of built-in features such as service hosting, instance management, asynchronous calls, synchronization, reliability, transaction management, disconnected queued calls and security to build best in class applications. "Programming WCF Services" focuses on the rationale behind particular design decisions, often shedding light on poorly-documented and little-understood aspects of SOA development. Developers and architects will learn not only the "how" of WCF programming, but also relevant design guidelines, best practices, and pitfalls. Original techniques and utilities provided by the author throughout the book go well beyond anything that can be found in conventional sources.Based on experience and insight gained while taking part in the strategic design of WCF and working with the team that implemented it, "Programming WCF Services" provides experienced working professionals with the definitive work on WCF. Not only will this book make you a WCF expert, it will make you a better software engineer. It's the Rosetta Stone of WCF.

    C. Grayling investigates why the institutions of representative democracy seem unable to sustain themselves against forces they were designed to manage, and why it matters. In each of five short chapters, he considers a moment in history in which the challenges we face today were first encountered, how they were overcome - or not - and with what consequences. With the advent of authoritarian leaders and the simultaneous rise of populism, representative democracy appears to be caught between a rock and a hard place, yet it is this space that it must occupy, argues Grayling, if a civilized society, that looks after all its people, is to flourish.

    Head First Ajax gives you an up-to-date perspective that lets you see exactly what you can do--and has been done--with Ajax. With it, you get a highly practical, in-depth, and mature view of what is now a mature development approach. Using the unique and highly effective visual format that has turned Head First titles into runaway bestsellers, this book offers a big picture overview to introduce Ajax, and then explores the use of individual Ajax components--including the JavaScript event model, DOM, XML, JSON, and more--as it progresses. You'll find plenty of sample applications that illustrate the concepts, along with exercises, quizzes, and other interactive features to help you retain what you've learned.Head First Ajax covers:The JavaScript event modelMaking Ajax requests with XMLHTTPREQUEST objectsThe asynchronous application modelThe Document Object Model (DOM)Manipulating the DOM in JavaScriptControlling the browser with the Browser Object ModelXHTML FormsPOST RequestsXML Syntax and the XML DOM treeXML Requests & ResponsesJSON -- an alternative to XMLAjax architecture & patternsThe Prototype LibraryThe book also discusses the server-side implications of building Ajax applications, and uses a black box approach to server-side components.Head First Ajax is the ideal guide for experienced web developers comfortable with scripting--particularly those who have completed the exercises in Head First JavaScript--and for experienced programmers in Java, PHP, and C# who want to learn client-side programming.

    It’s the latest in a long line of “Are you cool enough to use me?” programming languages, APIs, and toolkits. In that sense, it lands squarely in the tradition of Rails, and Ajax, and Hadoop, and even to some degree iPhone programming and HTML5.Dig a little deeper, and you’ll hear that Node.js (or, as it’s more briefly called by many, simply “Node”) is a server-side solution for JavaScript, and in particular, for receiving and responding to HTTP requests. If that doesn’t completely boggle your mind, by the time the conversation heats up with discussion of ports, sockets, and threads, you’ll tend to glaze over. Is this really JavaScript? In fact, why in the world would anyone want to run JavaScript outside of a browser, let alone the server?The good news is that you’re hearing (and thinking) about the right things. Node really is concerned with network programming and server-side request/response processing. The bad news is that like Rails, Ajax, and Hadoop before it, there’s precious little clear information available. There will be, in time — as there now is for these other “cool” frameworks that have matured — but why wait for a book or tutorial when you might be able to use Node today, and dramatically improve the maintainability.

     Fairies, demons, four-legged fiends, and, of course, zombies: the world is filled with fantastical beings, beautiful and scary.

    Oh, all right, Caesar didn't cry that, Kenneth Williams did in the movie Carry on Cleo. But nor did he sigh 'Et tu, brute?' as Shakespeare would have us believe. The history we think we know is full of misconceptions, mischiefs, misunderstandings ... and monks who misused their spell-checkers.What the general reader needs is a history that explores our ancestors with humour and compassion. 'Humour' and 'history' are not two words you often see in the same sentence: our past was a dangerous and dirty place full of cruel rulers, foul food and terrible toilets. A short life, not a merry one, for most. Dangerous days in which to live and, inevitably, die.Die dreadfully too. 'Murder breathed her bloody steam.' That's what rhymester Byron said when he looked at the crumbling Coliseum. The Roman Emperors: they came, they saw, they left behind their bloody steam. This is their story - it could be the funniest history you'll ever read. (Amazon UK)
