C# Multithreaded and Parallel Programming
Most modern machines have dual-core processors. This means that the present-day computer has the ability to multitask. Using multiple cores means your applications can process data faster and be more responsive to users. However, to fully exploit this in your applications, you need to write multithreading code. We will begin by covering some techniques that have been around since the beginning of .NET, including the BackgroundWorker component, timers, and the Thread class. We will use tasks, task factories, and parallel loops to develop multithreaded applications at a higher level than directly creating and managing individual threads. Finally, we will look at the tools Visual Studio provides for debugging parallel applications, common concurrent design patterns, and the latest updates in PLINQ and async. ...

AngularJS Test-driven Development
Starting with reviewing the test-driven development (TDD) life cycle, you will learn how Karma and Protractor make your life easier while running JavaScript unit tests. You will learn how Protractor is different from Selenium and how to test it entirely. This book is a walk-through to using TDD to build an AngularJS application containing a controller, model, and scope. Building on the initial foundational aspects, you will expand to include testing for multiple controllers, partial views, location references, CSS, and the HTML element. In addition, you will explore using a headless browser with Karma. You will also configure Karma file watching to automate testing and tackle components of AngularJS (controller, service, model, and broadcasting) using TDD. At the end of this book, you will extend explore how to pull data using an external API, setting up and configuring Protractor to use a standalone Selenium server, and setting up Travis CI and Karma to test your application. ...

CORS in Action
Suppose you need to share some JSON data with another application or service. If everything is hosted on one domain, it's a snap. But if the data is on another domain, the browser's "same-origin" policy stops you cold. CORS is a new web standard that enables safe cross-domain access without complex server-side code. Mastering CORS makes it possible for web and mobile applications to share data simply and securely. CORS in Action introduces CORS from both the server and the client perspective. It starts with making and enabling CORS requests and then explores performance, debugging, and security. You'll learn to build apps that can take advantage of APIs hosted anywhere and how to write APIs that expand your products to a wider range of users. For web developers comfortable with JavaScript. No experience with CORS is assumed. ...
