ASP.NET SignalR is the new solution to real-time communication between servers and clients in .NET. Use it to push new data to a web page or mobile device as soon as it becomes available, whether it's a notification, live chat, up-to-the-minute financial data, or a range of other exciting applications. Innovations like Google live search and live Facebook and Twitter updates are pushing users' expectations of the real-time web. With Pro ASP.NET SignalR, you can join this revolution and learn skills that will be valuable for years to come. Pro ASP.NET SignalR starts with an introduction to the real-time web. Learn about the technologies underlying the SignalR library, such as WebSockets and long-polling, and how SignalR elegantly flips between them depending on the capabilities of the client. Next, meet the concepts of hubs and persistent connections and how to use them to build the components of an ASP.NET SignalR application. Find out how to extend, test, debug, configure, scale, and host your applications, and how to target a range of clients, including Windows and iOS. The book rounds off with two case studies-a stock market price updater, and a collaborative drawing application-so you can get to grips with SignalR in a realistic scenario, using a broad range of the concepts covered in earlier chapters. As real-time updates to web and mobile apps become the norm, Pro ASP.NET SignalR will be your in-depth, one-stop companion to this new and exciting technology.

Threads are essential to Java programming, but learning to use them effectively is a nontrivial task. This new edition of the classic "Java Threads" shows you how to take full advantage of Java's threading facilities and brings you up-to-date with the watershed changes in Java 2 Standard Edition version 5.0 (J2SE 5.0). It provides a thorough, step-by-step approach to threads programming.

Java's threading system is simple relative to other threading systems. In earlier versions of Java, this simplicity came with tradeoffs: some of the advanced features in other threading systems were not available in Java. J2SE 5.0 changes all that: it provides a large number of new thread-related classes that make the task of writing multithreaded programs that much easier.

You'll learn where to use threads to increase efficiency, how to use them effectively, and how to avoid common mistakes. This book discusses problems like deadlock, race conditions, and starvation in detail, helping you to write code without hidden bugs.

"Java Threads," Third Edition, has been thoroughly expanded and revised. It incorporates the concurrency utilities from java.util.concurrent throughout. New chapters cover thread performance, using threads with Swing, threads and Collection classes, thread pools, and threads and I/O (traditional, new, and interrupted). Developers who cannot yet deploy J2SE 5.0 can use thread utilities provided in the Appendix to achieve similar functionality with earlier versions of Java.

Topics include:

Lock starvation and deadlock detection

Atomic classes and minimal synchronization (J2SE 5.0)

Interaction of Java threads with Swing, I/O, and Collection classes

Programmatically controlled locks and condition variables (J2SE 5.0)

Thread performance and security

Thread pools (J2SE 5.0)

Thread groups

Platform-specific thread scheduling

Task schedulers (J2SE 5.0)

Parallelizing loops for multiprocessor machines

In short, this new edition of "Java Threads" covers everything you need to know about threads, from the simplest animation program to the most complex applications. If you plan to do any serious work in Java, you will find this book invaluable.

This textbook grew out of notes for the ECE143 Programming for Data Analysis class that the author has been teaching at University of California, San Diego, which is a requirement for both graduate and undergraduate degrees in Machine Learning and Data Science. This book is ideal for readers with some Python programming experience. The book covers key language concepts that must be understood to program effectively, especially for data analysis applications. Certain low-level language features are discussed in detail, especially Python memory management and data structures. Using Python effectively means taking advantage of its vast ecosystem. The book discusses Python package management and how to use third-party modules as well as how to structure your own Python modules. The section on object-oriented programming explains features of the language that facilitate common programming patterns. After developing the key Python language features, the book moves on to third-party modules that are foundational for effective data analysis, starting with Numpy. The book develops key Numpy concepts and discusses internal Numpy array data structures and memory usage. Then, the author moves onto Pandas and details its many features for data processing and alignment. Because strong visualizations are important for communicating data analysis, key modules such as Matplotlib are developed in detail, along with web-based options such as Bokeh, Holoviews, Altair, and Plotly. The text is sprinkled with many tricks-of-the-trade that help avoid common pitfalls. The author explains the internal logic embodied in the Python language so that readers can get into the Python mindset and make better design choices in their codes, which is especially helpful for newcomers to both Python and data analysis. To get the most out of this book, open a Python interpreter and type along with the many code samples.

In today's rapidly changing technological world, it is increasingly important that web and desktop applications be accessible to everyone, including those of us with special needs. However, the legal requirements for accessibility are often convoluted and diffucult to understand, making it impossible for most developers to comply with the laws. In the first book on the market to address the topic, Author John Paul Mueller leads you through the maze of Section 508-the congressional law ensuring that all Americans have access to information technology-and offers comprehensive guidance on how to quickly and easily update your applications to conform to Section 508 requirements. To begin, Mueller outlines the Section 508 requirements that are relevant to web and desktop application developers, and explains the laws in language you can understand. Using extensive and varied program examples, Mueller continues on to teach you to write web and desktop applications that not only conform to Section 508 standards, but look forward to ensure long-term universal accessibility for all types of computer users. Specific topics include writing accessible web applications and desktop applications using Visual Basic .NET and Visual C# .NET, developing special application capabilities, using Microsoft and other third-party tools to develop accessible features, developing accessible scripting solutions, and more. The book even includes a directory of helpful organizations, agencies, and resources to help you with any further accessibility concerns you may have.
