    They teach you how to make games. This book does not show you how to make games. It shows you how to take your game project to the finish line. Many game projects never make it beyond the alpha state.Game Development Success Is All About The Inner Game.Being a successful game developer does not (just) mean being a great programmer, a smart game designer or a gifted artist. It means dominating the inner game of game making. This separates the pros from the wannabes. It's the knowledge of how to stay focused, motivated and efficient during your game projects. It's the skillset of keeping things simple and avoiding misleading dreams of the next overnight success. Finally it's about thinking as a salesperson, not just as a designer, programmer or artist.

    Only then do you write the code itself and, with the test spurring you on, you improve your design. In acceptance test driven development (ATDD), you use the same technique to implement product features, benefiting from iterative development, rapid feedback cycles, and better-defined requirements. TDD and its supporting tools and techniques lead to better software faster.Test Driven brings under one cover practical TDD techniques distilled from several years of community experience. With examples in Java and the Java EE environment, it explores both the techniques and the mindset of TDD and ATDD. It uses carefully chosen examples to illustrate TDD tools and design patterns, not in the abstract but concretely in the context of the technologies you face at work. It is accessible to TDD beginners, and it offers effective and less well known techniques to older TDD hands.Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.What's InsideLearn hands-on to test drive Java codeHow to avoid common TDD adoption pitfallsAcceptance test driven development and the Fit frameworkHow to test Java EE components-Servlets, JSPs, and Spring ControllersTough issues like multithreaded programs and data access code

    The boys are the first responders to a crashed airplane deep within the woods. It doesn’t take long to find out that this C-47 Skytrain had gone down in 1953 and was carrying a very mysterious and highly sensitive cargo. Very quickly, the CIA takes control of the crash site as Josh and Eddie find themselves under the microscope of the agency (for a very good reason!)! There are men in dark clothing watching them from around every corner. They seek the help of some familiar friends and some new acquaintances as well, while trying to find out what this mysterious cargo is and why it is still so important today. Thinking the CIA could be their worst nightmare, the boys could not have been more wrong. Who comes to town next will stop at nothing to reclaim what they say is theirs, and they are quick to prove it! Ultimately, Josh, Eddie and Brad must decide whether to let this one go, or to once again risk their lives to see it through. One thing is for sure…they cannot allow the cargo to fall into the wrong hands! …Be careful wishing for big adventures…one may find you!!!

    Falling bodies fall with predictable accelerations. Eclipses can be accurately forecast centuries in advance. Nuclear power plants generate electricity according to well-known formulas. But those examples are the tip of the iceberg. In Nature's Numbers, Ian Stewart presents many more, each charming in its own way.. Stewart admirably captures compelling and accessible mathematical ideas along with the pleasure of thinking of them. He writes with clarity and precision. Those who enjoy this sort of thing will love this book."—Los Angeles Times

    It's a book of great breadth."--Gregory Djanikian, Philadelphia Inquirer

    But what if there was a better way? A true electronic space drive, reliable, safe, and cheap to operate? But the drive system is only part of the problem; it takes money, management, and engineering to build a working spaceship. Lots of it. And even if you DO manage to build a working spaceship, what will you do with it? How can you recoup the initial investment and finance more ships? Threatened industries will try to shut the company down. Governments will try to take it over. How is a small, threatened company, barely a step from bankruptcy, to succeed despite such terrible odds? Eccentric genius Morton Sneyd and his grandson Chuck invent an interplanetary space drive, based on an idea from a long-lost Nikola Tesla notebook. From a new industrial revolution to the brink of global war, restless humanity presses onward, eventually to the first contact with an alien species. There will be changes...

    Create a tiny virtual environment, called a container, for your 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, such as libraries, making their footprints radically smaller, and the containerized applications are easy to install, manage, and remove. Developers can package their applications without worrying about environment-specific deployment concerns, and the operations team gets cleaner, more efficient systems across the board. Better still, Docker is free and open source.Docker in Action teaches readers how to create, deploy, and manage applications hosted in Docker containers. The book starts with a clear explanation of the Docker model of virtualization, comparing this approach to the traditional hypervisor model. Developers will learn how to package applications in containers, including specific techniques for testing and distributing applications via Docker Hub and other registries. Readers will learn 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 teaches you how to orchestrate containers and applications from installation to removal. Along the way, you'll learn techniques for using Docker on systems ranging from your personal dev-and-test machine to full-scale cloud deployments.
