This practical guide shows how Apache ZooKeeper helps you manage distributed systems, so you can focus mainly on application logic. Even with ZooKeeper, implementing coordination tasks is not trivial, but this book provides good practices to give you a head start, and points out caveats that developers and administrators alike need to watch for along the way.In three separate sections, ZooKeeper contributors Flavio Junqueira and Benjamin Reed introduce the principles of distributed systems, provide ZooKeeper programming techniques, and include the information you need to administer this service.Learn how ZooKeeper solves common coordination tasksExplore the ZooKeeper API’s Java and C implementations and how they differUse methods to track and react to ZooKeeper state changesHandle failures of the network, application processes, and ZooKeeper itselfLearn about ZooKeeper’s trickier aspects dealing with concurrency, ordering, and configurationUse the Curator high-level interface for connection managementBecome familiar with ZooKeeper internals and administration tools

    Due to their monopoly position in web browsers, and the fact web browsers have spread from PCs to phones, tablets and TVs; their status will continue to grow and grow. Despite their success, many software engineers are apprehensive about JavaScript and HTML. This apprehensiveness is not completely unfounded; both JavaScript and HTML were rushed in their early years, and driven by commercial rather than engineering interests. As a result, many dubious features crept into these languages. Due to backwards compatibility concerns, most of these features still remain. In addition, many software engineers have used these languages without ever learning them. JavaScript and HTML have low barriers to entry, and this, along with their similarity to other languages, led many software engineers to conclude that there really was nothing much to learn. If you have not used JavaScript and HTML for a number of years, or if you are a programmer or software engineer using other languages, you may be surprised at what they now offer. Browser based web applications are now capable of matching or exceeding the sophistication and scale of traditional desktop applications. In order to create complex web applications however, it is essential to learn these languages. This book takes the point of view that once you have a strong grasp of the fundamentals, the details will take care of themselves. It will not present you with long lists of APIs, or intricate details of every attribute, these can be found in reference manuals. It will focus on the details of each language that are fundamental to understanding how they work. This book will guide you through the process of developing a web application using HTML5, Javascript, jQuery and CSS. It contains the following content: 1. An introduction to the HTML5 markup language, and how it differs from HTML4 and XHTML. 2. An introduction to JavaScript, including an in-depth look at its use of objects and functions, along with the design patterns that support the development of robust web applications. 3. An introduction to jQuery selection, traversal, manipulation and events. 4. An in-depth look at the Web storage and IndexedDB APIs for client side data storage. 5. A guide to implementing offline web applications with the Application Cache API. 6. An introduction to the ways JavaScript can interact with the users file-system using the FileReader API. 7. The use of Web Workers in a web application to execute algorithms on background threads. 8. An introduction to AJAX, and the jQuery API supporting AJAX. 9. An introduction to Server Sent Events and Web Sockets. All subjects are introduced in the context of a sample web application. This book is intended for anyone with at least a superficial knowledge of HTML and programming.

    If you are serious about developing with the C# language, you need this book." -Bill Craun, Principal Consultant, Ambassador Solutions, Inc. "More Effective C# is an opportunity to work beside Bill Wagner. Bill leverages his knowledge of C# and distills his expertise down to some very real advice about programming and designing applications that every serious Visual C# user should know. More Effective C# is one of those rare books that doesn't just regurgitate syntax, but teaches you how to use the C# language." -Peter Ritchie, Microsoft MVP: Visual C# "More Effective C# is a great follow-up to Bill Wagner's previous book. The extensive C# 3.0 and LINQ coverage is extremely timely!" -Tomas Restrepo, Microsoft MVP: Visual C++, .NET, and Biztalk Server "As one of the current designers of C#, it is rare that I learn something new about the language by reading a book. More Effective C# is a notable exception. Gently blending concrete code and deep insights, Bill Wagner frequently makes me look at C# in a fresh light-one that really makes it shine. More Effective C# is at the surface a collection of very useful guidelines. Look again. As you read through it, you'll find that you acquire more than just the individual pieces of advice; gradually you'll pick up on an approach to programming in C# that is thoughtful, beautiful, and deeply pleasant. While you can make your way willy-nilly through the individual guidelines, I do recommend reading the whole book-or at least not skipping over the chapter introductions before you dive into specific nuggets of advice. There's perspective and insight to be found there that in itself can be an important guide and inspiration for your future adventures in C#." -Mads Torgersen, Program Manager, Visual C#, Microsoft "Bill Wagner has written an excellent book outlining the best practices for developers who work with the C# language. By authoring More Effective C#, he has again established himself as one of the most important voices in the C# community. Many of us already know how to use C#. What we need is advice on how to hone our skills so that we can become wiser programmers. There is no more sophisticated source of information on how to become a first-class C# developer than Bill Wagner's book. Bill is intelligent, thoughtful, experienced, and skillful. By applying the lessons from this book to your own code, you will find many ways to polish and improve the work that you produce." -Charlie Calvert, Community Program Manager, Visual C#, Microsoft In More Effective C#, Microsoft C# MVP and Regional Director Bill Wagner introduces fifty brand-new ways to write more efficient and more robust software. This all-new book follows the same format as Wagner's best-selling Effective C# (Addison-Wesley, 2005), providing clear, practical explanations, expert tips, and plenty of realistic code examples. Wagner shows how to make the most of powerful innovations built into Microsoft's new C# 3.0 and .NET Framework 3.5, as well as advanced C# language capabilities not covered in his previous book. Drawing on his unsurpassed C# experience, the author reveals new best practices for working with LINQ, generics, metaprogramming, and many other features. He also uncovers practices that compromise performance or reliability and shows exactly how to avoid them. More Effective C# shows how to Use generics to express your design intent more effectively Master advanced generics techniques, such as constraints, method constraints, and generic specialization Use the multithreaded techniques you'll need to work with the .NET framework every day Express modern design idioms using the rich palette of C# language features Successfully mix object oriented and functional programming constructs Create composable interfaces and avoid confusion in public interfaces Use extension methods to separate contracts from implementation Program successfully with C# closures and anonymous types Write more effective LINQ queries Make the most of LINQ Lazy Evaluation Queries and Lambda Expressions Distinguish and convert between delegates and expression trees Efficiently utilize nullable types and partial classes Use implicit properties for mutable, nonserializable data You're already a successful C# programmer-this book can help you become an outstanding one.

    . . . Put this one on your must-have list if you have software, love software, hate programmers, or even ARE a programmer, because Mr. Platt (who teaches programming) has set out to puncture the bloated egos of all those who think that just because they can write a program, they can make it easy to use. . . . This book is funny, but it is also an important wake-up call for software companies that want to reduce the size of their customer support bills. If you were ever stuck for an answer to the question, 'Why do good programmers make such awful software?' this book holds the answer."--John McCormick, Locksmith columnist, TechRepublic.com "I must say first, I don't get many computing manuscripts that make me laugh out loud. Between the laughs, Dave Platt delivers some very interesting insight and perspective, all in a lucid and engaging style. I don't get much of that either!"--Henry Leitner, assistant dean for information technology andsenior lecturer on computer science, Harvard University "A riotous book for all of us downtrodden computer users, written in language that we understand."--Stacy Baratelli, author's barber "David's unique take on the problems that bedevil software creation made me think about the process in new ways. If you care about the quality of the software you create or use, read this book."--Dave Chappell, principal, Chappell & Associates "I began to read it in my office but stopped before I reached the bottom of the first page. I couldn't keep a grin off my face! I'll enjoy it after I go back home and find a safe place to read."--Tsukasa Makino, IT manager "David explains, in terms that my mother-in-law can understand, why the software we use today can be so frustrating, even dangerous at times, and gives us some real ideas on what we can do about it."--Jim Brosseau, Clarrus Consulting Group, Inc. A Book for Anyone Who Uses a Computer Today...and Just Wants to Scream! Today's software sucks. There's no other good way to say it. It's unsafe, allowing criminal programs to creep through the Internet wires into our very bedrooms. It's unreliable, crashing when we need it most, wiping out hours or days of work with no way to get it back. And it's hard to use, requiring large amounts of head-banging to figure out the simplest operations.It's no secret that software sucks. You know that from personal experience, whether you use computers for work or personal tasks. In this book, programming insider David Platt explains why that's the case and, more importantly, why it doesn't have to be that way. And he explains it in plain, jargon-free English that's a joy to read, using real-world examples with which you're already familiar. In the end, he suggests what you, as a typical user, without a technical background, can do about this sad state of our software--how you, as an informed consumer, don't have to take the abuse that bad software dishes out.As you might expect from the book's title, Dave's expose is laced with humor--sometimes outrageous, but always dead on. You'll laugh out loud as you recall incidents with your own software that made you cry. You'll slap your thigh with the same hand that so often pounded your computer desk and wished it was a bad programmer's face. But Dave hasn't written this book just for laughs. He's written it to give long-overdue voice to your own discovery--that software does, indeed, suck, but it shouldn't.
