Mastering Akka. A hands-on guide to build application using the Akka framework

Christian Baxter

For a programmer, writing multi-threaded applications is critical as it is important to break large tasks into smaller ones and run them simultaneously. Akka is a distributed computing toolkit that uses the abstraction of the Actor model, enabling developers to build correct, concurrent, and distributed applications using Java and Scala with ease. The book begins with a quick introduction that simplifies concurrent programming with actors. We then proceed to master all aspects of domain-driven design. We’ll teach you how to scale out with Akka Remoting/Clustering. Finally, we introduce Conductr as a means to deploy to and manage microservices across a cluster.

Microsoft AJAX Library Essentials: Client-side ASP.NET AJAX 1.0 Explained. A practical tutorial to enhancing the user experience of your ASP.NET web applications with the final release of the Microsoft AJAX Library

Cristian Darie, Bogdan Brinzarea

Microsoft AJAX Library Essentials is a practical reference for the client-side library of the ASP.NET AJAX Framework 1.0, and a tutorial for the underlying technologies and techniques required to use the library at its full potential. The main goal of this book is to get you comfortable with the Microsoft AJAX Library, a huge set of functions that can be used for developing powerful client-side functionality.Beginning with a hands-on tour of the basic technologies associated with AJAX, JavaScript, XMLHttpRequest, JSON, and the DOM, you'll move on to a crash course in the Microsoft AJAX tools. You will learn, through numerous step-by-step exercises, how to create basic AJAX applications, how the object-based programming model of JavaScript works, and how Microsoft AJAX Library extends this model. You'll understand the architecture of the Microsoft AJAX components, how they all fit together, and exactly what they can do for you. Then you will learn how to use the Microsoft AJAX Library in your web projects, and a detailed case study will walk you through creating your own customized client components. At every stage of your journey, you'll be able to try out examples to illuminate the theory, and consolidate your understanding. In addition to learning about the client and server controls, you'll also see how to handle errors and debug your AJAX applications.To complement your new found skills, the book ends with a visual reference of the Microsoft AJAX Library namespaces and classes, including diagrams and quick explanations for all the classes mentioned in the book, providing an invaluable reference you will turn to again and again.

Salesforce Anti-Patterns. Create powerful Salesforce architectures by learning from common mistakes made on the platform

Lars Malmqvist

Salesforce Anti-Patterns teaches you to spot errors in Salesforce patterns that may seem like a good idea at first but end up costing you dearly. This book will enable Salesforce developers and architects to understand how ingenious Salesforce architectures can be created by studying anti-patterns and solutions to problems that can later lead to serious implementation issues. While there are several books on the market that start with the question, “How do I create great Salesforce architecture?” and proceed to a solution from there, this book instead starts by asking, “What tends to go wrong with Salesforce architectures?” and proceeds to a solution from there.In this book, you’ll find out how to identify and mitigate anti-patterns in the technical domains of system architecture, data architecture, and security architecture, along with anti-patterns in the functional domain of solution architecture as well as for integration architecture. You’ll also learn about common anti-patterns affecting your Salesforce development process and governance and, finally, how to spot common problems in how architects communicate their solutions.By the end of this Salesforce book, you’ll have gained the confidence to architect and communicate solutions on the Salesforce platform while dodging common mistakes.
