DESCRIPTION In today's world, user interfaces have to be highly dynamic, asynchronous, and reliable. To meet these demands, the programming world is undergoing a radical shift towards something called Functional Reactive Programming (FRP), or just Reactive Programming. FRP offers programmers a new way to construct their applications so that they respond directly to change. And developers spend less time tracing obscure problems and more time focusing on what their code should be doing. Grokking Reactive User Interfaces teaches programmers a new way of thinking about programs and data as well as how to build robust and extensible user interfaces. This well-illustrated book presents lots of concrete, real-world problems and then shows how FRP helps to solve them. It begins by looking at examples that get readers into the mindset of data flows and goes on to introduce the concept of a View Model. Readers also learn how FRP enables them to better manage change and introduce new features. The final part of this book focuses on higherlevel application design concerns and strategies as you look at architectural approaches and frameworks that work well with FRP thinking. KEY FEATURES • Provides lots of illustrations and real-life app examples • Teaches a new way of thinking about programs and data • Using FRP in day-to-day programming • Teaches how to handle increasing complexity in UIs AUDIENCE Readers should have a basic understanding of mobile UI development and be familiar with traditional object-oriented programming paradigms. ABOUT THE TECHNOLOGY FRP offers a new way to construct applications so that they respond directly to change. FRP is not a typical technology B that obviously and immediately replaces an inferior technology A. It’s more of a way of thinking rather than a mechanical solution.

DESCRIPTION The idea behind Docker, a free an open source program, is simple. Create a tiny virtual environment, called a container, for an application that includes only its particular set of dependencies. The Docker engine accounts for, manages, and builds these containers through functionality provided by the host operating system. Software running inside containers share the Linux OS and other resources, making their footprints radically smaller, and the containerized applications easy to install, manage, and remove. Applications can be packaged without worrying about environment-specific deployment concerns, and the operations team gets cleaner, more efficient systems across the board. Docker in Action starts with a clear explanation of the Docker model of virtualization and shows how to create, deploy, and manage applications hosted in Docker containers. It offers specific techniques for testing and distributing applications via Docker Hub and other registries. It shows how to take advantage of the Linux OS features that Docker uses to run programs securely, and how to manage shared resources. Using carefully-designed examples, the book guides readers on orchestrating containers and applications from installation to removal. Along the way, it teaches techniques for using Docker on systems ranging from personal dev-and-test machine to full-scale cloud deployments. KEY SELLING POINTS Explains the "why" and "how" of Docker Simplify software installation Addresses many of the everyday software problems faced by developers AUDIENCE Readers need a working knowledge of installing and running software on the Linux OS. No prior experience with Docker or other virtualization technologies is required. ABOUT THE TECHNOLOGY Docker provides software logistics. It uses "container" abstraction to hide complex tooling for packaging software, and running software in virtualized environments without overhead of a full virtual machine. Docker and the container abstraction are driving a change in the way people write, test, deploy, and distribute software.
