This book shows you how to run experiments on your website using A/B testing - and then takes you a huge step further by introducing you to bandit algorithms for website optimization. Author John Myles White shows you how this family of algorithms can help you boost website traffic, convert visitors to customers, and increase many other measures of success. This is the first developer-focused book on bandit algorithms, which have previously only been described in research papers. You'll learn about several simple algorithms you can deploy on your own websites to improve your business including the epsilon-greedy algorithm, the UCB algorithm and a contextual bandit algorithm. All of these algorithms are implemented in easy-to-follow Python code and be quickly adapted to your business's specific needs.

Beginning Amazon Web Services with Node.js teaches any novice Node.js developer to configure, deploy, and maintain scalable small to large scale Node.js applications in Amazon Web Services. Hosting a Node.js application in a production environment usually means turning to PaaS hosting, but this approach brings problems. Deploying Node.js directly to AWS solves the problems you encounter in these situations, enabling you to cut out the middle man. You will begin with a basic RESTful web service in Node.js, using the popular Express.js framework, pre-built and ready to run in your local environment. You will be introduced to the most powerful tools in AWS, and learn how to configure your project to take advantage of them. You will be guided through the steps of getting the various key components to work together on AWS. Through code samples using the AWS JavaScript SDK and tutorials in the AWS console, you will gain the knowledge to incorporate secure user authentication, server auto-scaling, a load balancer, CDN, customized caching behavior, and outage monitoring. Node.js is single-threaded, and designed to run high input / high output applications, making it ideal for the cloud environment. If your main task is handling a high volume of requests over HTTP / the web, it will scale very well in proportion to the computing power you allocate to it. Amazon Web Services offers a broad set of services that help organizations move faster, lower costs, and scale applications. Trusted by the largest enterprises and start-ups alike, AWS powers a wide variety of workloads across a broad spectrum. If leveraged properly, you can build a Node.js app on AWS which can automatically power itself up to handle a massive volume of traffic, and then scale back down to a lighter configuration when user demand has dropped. Amazon Web Services offers a broad set of services that help organizations move faster, lower costs, and scale applications. Get started with Node.js and AWS using this book today.

Beginning JSON is the definitive guide to JSON - JavaScript Object Notation - today's standard in data formatting for the web.

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.
