Akka uses Actors-independently executing processes that communicate via message passing—as the foundation for fault-tolerant applications where individual actors can fail without crashing everything. Perfect for high-volume applications that need to scale rapidly, Akka is an efficient foundation for event-driven systems that want to scale elastically up and out on demand, both on multi-core processors and across server nodes.Akka in Action is a comprehensive tutorial on building message-oriented systems using Akka. The book takes a hands-on approach, where each new concept is followed by an example that shows you how it works, how to implement the code, and how to (unit) test it. You'll learn to test and deploy an actor system and scale it up and out, showing off Akka's fault tolerance. As you move along, you'll explore a message-oriented event-driven application in Akka. You'll also tackle key issues like how to model immutable messages and domain models, and apply patterns like Event Sourcing, and CQRS. The book concludes with practical advice on how to tune and customize a system built with Akka.

    

    It was going fine until I met her. Remy Harris, the wild eyed vixen no man can pin down. She’s more than willing to have a good time, but I’m looking for so much more than that. RemyLove ‘em and leave ‘em. It’s safer that way. In my experience all men are looking for is a good time anyway. It’s better to give them what they want and walk away before they can do the same to you. When I needed a calculus tutor I never expected to find one who’s so...sexy. Since when are nerds so hot? **While every book in this series can be read as a stand alone, you will likely get more enjoyment from Impossible Girl if you've read Worth the Wait and Naughty Angel first**mature content

    If you have read the Swift Programming Guide, and want to explore more, this book is for you.Swift is a great language for systems programming, but also lends itself for very high-level programming. We'll explore both high-level topics (for example, programming with generics and protocols), as well as low-level topics (for example, wrapping a C library and string internals).

    You want to develop software in the most effective, efficient way possible. This book gives you the answers you’ve been looking for in friendly, clear language.We’ll cover, in depth, the core concepts of Clojure: immutable collections, concurrency, pure functions, and state management. You’ll finally get the complete picture you’ve been looking for, rather than dozens of puzzle pieces you must assemble yourself. First, we focus on Clojure thinking. You’ll discover the simple architecture of Clojure software, effective development processes, and how to structure applications. Next, we explore the core concepts of Clojure development. You’ll learn how to model with immutable data; write simple, pure functions for efficient transformation; build clean, concurrent designs; and structure your code for elegant composition. Finally, we move beyond pure application development and into the real world. You’ll understand your application’s configuration and dependencies, connect with other data sources, and get your libraries and applications out the door.Go beyond the toy box and into Clojure’s way of thinking. By the end of this book, you’ll have the tools and information to put Clojure’s strengths to work.https://pragprog.com/book/vmclojeco/c...

    This junior novel is based on the high-anticipated Walt Disney Studios film, Tomorrowland, and includes a full-color photo insert!

    That's what happened to little ole' me, Eve Stone. Only that it's not love that the breathtakingly handsome fae wants from me. Aradaen Starlight wants to save his kingdom, and for that he needs my virginity. Mating with me will make him invincible, but that will be that. He can't get serious with me, because he's bound to further his race with a woman of his kind, not to mention that I, as a human, am way beneath fae royalty. To his courts, it's a jest of nature that I of all people should be the Starlight prince's fated mate. But when it turns out that I have magic in my blood, I become interesting to them. The prince and I make an agreement in order to save our worlds, but we cannot fall in love. If we do, all hell will break loose.

    Yet despite dazzling success with the public, it never received its fair share of praise from the critics. Gene Kelly's genius as a performer is there for all to see. What is less acknowledged is his innovatory contribution as director. Peter Wollen has finally done justice to this landmark film. In a brilliant shot-by-shot analysis of the famous title number, illustrated by specially produced frame stills, he shows how skillfully Kelly binds the dance and musical elements into the narrative, and how he successfully combines two distinctive traditions within American Dance, tap and ballet.Scriptwriters Betty Comden and Adolph Green, and indeed Kelly himself, were all under threat from the McCarthyism which menaced Hollywood at this time. The ethos in which the film was conceived could not long survive in the era of blacklisting. Wollen argues convincingly that "Singin' in the Rain" was the high point in the careers of those who worked on it.

    Whether it's a data format like JSON, a network protocol like SMTP, a server configuration file for Apache, a PostScript/PDF file, or a simple spreadsheet macro language--ANTLR v4 and this book will demystify the process. ANTLR v4 has been rewritten from scratch to make it easier than ever to build parsers and the language applications built on top. This completely rewritten new edition of the bestselling Definitive ANTLR Reference shows you how to take advantage of these new features. Build your own languages with ANTLR v4, using ANTLR's new advanced parsing technology. In this book, you'll learn how ANTLR automatically builds a data structure representing the input (parse tree) and generates code that can walk the tree (visitor). You can use that combination to implement data readers, language interpreters, and translators. You'll start by learning how to identify grammar patterns in language reference manuals and then slowly start building increasingly complex grammars. Next, you'll build applications based upon those grammars by walking the automatically generated parse trees. Then you'll tackle some nasty language problems by parsing files containing more than one language (such as XML, Java, and Javadoc). You'll also see how to take absolute control over parsing by embedding Java actions into the grammar. You'll learn directly from well-known parsing expert Terence Parr, the ANTLR creator and project lead. You'll master ANTLR grammar construction and learn how to build language tools using the built-in parse tree visitor mechanism. The book teaches using real-world examples and shows you how to use ANTLR to build such things as a data file reader, a JSON to XML translator, an R parser, and a Java class->interface extractor. This book is your ticket to becoming a parsing guru!What You Need: ANTLR 4.0 and above. Java development tools. Ant build system optional (needed for building ANTLR from source)

    Windows Presentation Foundation (WPF) is the recommended technology for creating Windows user interfaces, giving you the power to create richer and more compelling applications than you dreamed possible.

    As in other areas of social sciences, some Muslim thinkers and scholars have developed an amazing skill for the unthinking repetition and blind copying of Western, non-Islamic ideas and practices. “In the Lizard’s Hole” is a Prophetic epitaph that describes this activity very well. Some Muslim psychologists insist dogmatically on prying even into lizard’s holes that have been partly or totally abandoned by their Western counterparts. But do Muslims really need modern psychology at all? Is modern psychology wholly Western? Is there a way in which it could be reconciled with Islam? These burning questions lie lurking behind the dilemma of Muslim psychologists.
