Traditionally, JavaScript has been a single-threaded language. Nearly all online forum posts, books, online documentation, and libraries refer to the language as single threaded. Thanks to recent advancements in the language--such as the Atomics and SharedArrayBuffers objects and Web Workers in the browser--JavaScript is now a multi-threaded language. These features will go down as being the biggest paradigm shift for the world's most popular programming language. Multithreaded JavaScript explores the various features that JavaScript runtimes have at their disposal for implementing multithreaded programming, providing both practical real-world examples, as well as reference material. Learn what multithreaded programming is and how you can benefit from it Understand the differences between a web worker, a service worker, and a worker thread Know when and when not to use threads in an application Orchestrate communication between threads by leveraging the Atomics object Build high-performance applications using the knowledge you gain from this book Benchmark performance to learn if you'll benefit from multithreading

Harnessing Hibernate is an ideal introduction to the popular framework that lets Java developers work with information from a relational database easily and efficiently. Databases are a very different world than Java objects, and they often involve people with different skills and specializations. With Hibernate, bridging these two worlds is significantly easier, and with this book, you can get up to speed with Hibernate quickly. Rather than present you with another reference, Harnessing Hibernate lets you explore the system, from download and configuration through a series of projects that demonstrate how to accomplish a variety of practical goals. The new edition of this concise guide walks you through Hibernate's primary features, which include mapping from Java classes to database tables, and from Java data types to SQL data types. You will also learn about Hibernate's data query and retrieval facilities, and much more. By reading and following along with the examples, you can get your own Hibernate environment set up quickly and start using it for real-world tasks right away. Harnessing Hibernate teaches you how to: * Perform Object/Relational mapping * Work with persistent data from Java code * Work with groups and relationships between objects * Extend Hibernate's rich type support for your own needs * Simplify query creation using criteria and examples * Use the Hibernate Query Language (HQL) and understand how it differs from SQL * Use Hibernate in conjunction with Spring * Use Hibernate in conjunction with other packages, such as the Stripes web framework and the Eclipse IDE Once you're past the first few chapters, you can jump to topics that you find particularly interesting or relevant. All background material and explanations of how Hibernate works and why is in the service of a focused task. Source code can be downloaded from the book's website. If using SQL is an uncomfortable chore, Harnessing Hibernate offers you an effective and trouble-free method for working with the information you store in your applications.

JBoss 3.2 Deployment and Administration is a guide to the variety of configurative, administrative, and deployment tasks that associated with setting up and running J2EE components on the JBoss application server. Deploying J2EE applications and configuring the application server is one of the most tricky and non-standard elements of J2EE development. Each server interprets and implements the specifications differently, adding its own proprietary features and functionality.JBoss is the leading open source J2EE application server. It was the JavaWorld 2002 Editor's choice for Best Application Server. Its downloads are an order of magnitude greater than any other server (200,000). TogetherSoft poll places JBoss as the leading choice for development (43 per cent). The basic runtime and source is free, however you can pay for documentation and support services.

ASP.NET 2.0 is the next version of ASP.NET, due to be revealed to the public for the first time as part of version 2.0 of the .NET Framework at PDC in October 2003.ASP.NET 2.0 Revealed covers all these features from the perspective of an ASP.NET developer.Prior knowledge of ASP.NET 1.x is assumed, as only people with that knowledge will be using ASP.NET at such an early stage.Because this is such a radical change, all ASP.NET developers will want to know as soon as possible what the new version contains.

The absolute cutting edge for application development at the moment is using Macromedia's Flash MX (the premier software for designing fantastic looking interfaces) with Microsoft's .NET framework (tremendously powerful server-side technology).
