Annotation Gain hands-on experience with PureMVC, the popular open source framework for developing maintainable applications with a Model-View-Controller architecture. In this concise guide, PureMVC creator Cliff Hall teaches the fundamentals of PureMVC development by walking you through the construction of a complete non-trivial Adobe AIR application. Through clear explanations and numerous ActionScript code examples, youll learn best practices for using the frameworks classes in your day-to-day work. Discover how PureMVC enables you to focus on the purpose and scope of your application, while the framework takes care of the plumbing in a maintainable and portable way. Get a detailed overview of the PureMVC process for developing your applicationModel the domain by designing the schema and creating framework-agnostic value objectsImplement framework-agnostic View components that expose an API of events and propertiesUse the Proxy pattern to keep track of value objects and hide service interactionFacilitate two-way communication between a View component and the rest of the applicationStitch the Model and View tiers together with command objects in the ControllerManage problematic View component life cycles, and learn how to reuse the Model tier.

Today's ActionScript-based applications require increasingly sophisticated architectures and code. This eBook aids intermediate and advanced ActionScript developers in learning how to plan and build applications more effectively. You'll learn how to apply design patterns as solutions to common programming scenarios. Beyond a reference, Advanced ActionScript with Design Patterns is a practical guide complete with sample mini-applications illustrating each design pattern. The accompanying media files include all the lesson files needed to work with the text. Joey Lott works with ActionScript.

Now that ActionScript is reengineered from top to bottom as a true object-oriented programming (OOP) language, reusable design patterns are an ideal way to solve common problems in Flash and Flex applications. If you're an experienced Flash or Flex developer ready to tackle sophisticated programming techniques with ActionScript 3.0, this hands-on introduction to design patterns is the book you need. ActionScript 3.0 Design Patterns takes you step by step through the process, first by explaining how design patterns provide a clear road map for structuring code that actually makes OOP languages easier to learn and use. You then learn about various types of design patterns and construct small abstract examples before trying your hand at building full-fledged working applications outlined in the book. Topics in ActionScript 3.0 Design Patterns include: Key features of ActionScript 3.0 and why it became an OOP language OOP characteristics, such as classes, abstraction, inheritance, and polymorphism The benefits of using design patterns Creational patterns, including Factory and Singleton patterns Structural patterns, including Decorator, Adapter, and Composite patterns Behavioral patterns, including Command, Observer, Strategy, and State patterns Multiple design patterns, including Model-View-Controller and Symmetric Proxy designs During the course of the book, you'll work with examples of increasing complexity, such as an e-business application with service options that users can select, an interface for selecting a class of products and individual products in each class, an action game application, a video record and playback application, and many more. Whether you're coming to Flash and Flex from Java or C++, or have experience with ActionScript 2.0, ActionScript 3.0 Design Patterns will have you constructing truly elegant solutions for your Flash and Flex applications in no time.

A Beginner’s Guide to 3D Modeling is a project-based, straightforward introduction to computer-aided design (CAD). You’ll learn how to use Autodesk Fusion 360, the world’s most powerful free CAD software, to model gadgets, 3D print your designs, and create realistic images just like an engineering professional—with no experience required! Hands-on modeling projects and step-by-step instructions throughout the book introduce fundamental 3D modeling concepts. As you work through the projects, you’ll master the basics of parametric modeling and learn how to create your own models, from simple shapes to multipart assemblies. Once you’ve mastered the basics, you’ll learn more advanced modeling concepts like sweeps, lofts, surfaces, and rendering, before pulling it all together to create a robotic arm. You’ll learn how to: • Design a moving robotic arm, a door hinge, a teapot, and a 20-sided die • Create professional technical drawings for manufacturing and patent applications • Model springs and other complex curves to create realistic designs • Use basic Fusion 360 tools like Extrude, Revolve, and Hole • Master advanced tools like Coil and Thread Whether you’re a maker, hobbyist, or artist, A Beginner’s Guide to 3D Modeling is certain to show you how to turn your ideas into professional models. Go ahead—dust off that 3D printer and feed it your amazing designs.

The software development ecosystem is constantly changing, providing a constant stream of new tools, frameworks, techniques, and paradigms. Over the past few years, incremental developments in core engineering practices for software development have created the foundations for rethinking how architecture changes over time, along with ways to protect important architectural characteristics as it evolves. This practical guide ties those parts together with a new way to think about architecture and time.
