Less obviously, the ABSTRACT value of a variable is never used if the program places no By determining, statically, where the structure of a constraints on its representation. Furthermore, program requires sets of variables to share a common communication induces representation constraints: a representation, we can identify abstract data types, detect necessary condition for a value defined at one site to be abstraction violations, find unused variables, functions, used at another is that the two values must have the same and fields of data structures, detect simple errors in representation1. operations on abstract datatypes, and locate sites of possible references to a value. We compute representation By extending the notion of representation we can encode sharing with type inference, using types to encode other kinds of useful information. We shall see, for representations. The method is efficient, fully automatic, example, how a refinement of the treatment of pointers and smoothly integrates pointer aliasing and higher-order allows reads and writes to be distinguished, and storage functions. We show how we used a prototype tool to leaks to be exposed. answer a user’s questions about a 17,000 line program We show how to generate and solve representation written in C. -
Haxe Game Development Essentials
F re e S a m p le Community Experience Distilled Haxe Game Development Essentials Create games on multiple platforms from a single codebase using Haxe and the HaxeFlixel engine Jeremy McCurdy In this package, you will find: The author biography A preview chapter from the book, Chapter 1 'Getting Started' A synopsis of the book’s content More information on Haxe Game Development Essentials About the Author Jeremy McCurdy is a game developer who has been making games using ActionScript, C#, and Haxe for over four years. He has developed games targeted at iOS, Android, Windows, OS X, Flash, and HTML5. He has worked on games that have had millions of gameplay sessions, and has built games for many major North American television networks. He is the games technical lead at REDspace, an award-winning interactive studio that has worked for some of the world's largest brands. They are located in Nova Scotia, Canada, and have been building awesome experiences for 15 years. Preface Developing games that can reach a wide audience can often be a serious challenge. A big part of the problem is fi guring out how to make a game that will work on a wide range of hardware and operating systems. This is where Haxe comes in. Over the course of this book, we'll look at getting started with Haxe and the HaxeFlixel game engine, build a side-scrolling shooter game that covers the core features you need to know, and prepare the game for deployment to multiple platforms. After completing this book, you will have the skills you need to start producing your own cross-platform Haxe-driven games! What this book covers Chapter 1, Getting Started, explains setting up the Haxe and HaxeFlixel development environment and doing a quick Hello World example to ensure that everything is working. -

Being as a general purpose programming language, it is influenced by many ancestors including, Erlang, Haskell, Java, Lisp, OCaml, Scheme, and Smalltalk. Scala has many attractive features, such as cross-platform taking advantage of JVM; as well as with higher level abstraction agnostic to the developer providing immutability with persistent data structures, pattern matching, type inference, higher or- der functions, lazy evaluation and many other functional programming features. -

First Steps in Scala Typing Static Typing Dynamic and Static Typing
CS206 First steps in Scala CS206 Typing Like Python, Scala has an interactive mode, where you can try What is the biggest difference between Python and Scala? out things or just compute something interactively. Python is dynamically typed, Scala is statically typed. Welcome to Scala version 2.8.1.final. In Python and in Scala, every piece of data is an object. Every scala> println("Hello World") object has a type. The type of an object determines what you Hello World can do with the object. Dynamic typing means that a variable can contain objects of scala> println("This is fun") different types: This is fun # This is Python The + means different things. To write a Scala script, create a file with name, say, test.scala, def test(a, b): and run it by saying scala test.scala. print a + b In the first homework you will see how to compile large test(3, 15) programs (so that they start faster). test("Hello", "World") CS206 Static typing CS206 Dynamic and static typing Static typing means that every variable has a known type. Dynamic typing: Flexible, concise (no need to write down types all the time), useful for quickly writing short programs. If you use the wrong type of object in an expression, the compiler will immediately tell you (so you get a compilation Static typing: Type errors found during compilation. More error instead of a runtime error). robust and trustworthy code. Compiler can generate more efficient code since the actual operation is known during scala> varm : Int = 17 compilation. m: Int = 17 Java, C, C++, and Scala are all statically typed languages. -
Framework Overview with UML Diagrams
Framework Overview with UML Diagrams Learn to Build Robust, Scalable and Maintainable Applications using PureMVC Framework Overview This document discusses the classes and interfaces of the PureMVC framework; illustrating their roles, responsibilities and collaborations with simple UML (Unified Modeling Language) diagrams. The PureMVC framework has a very narrow goal. That is to help you separate your application’s coding concerns into three discrete tiers; Model, View and Controller. In this implementation of the classic MVC design meta-pattern, the application tiers are represented by three Singletons (a class where only one instance may be created). A fourth Singleton, the Façade, simplifies development by providing a single interface for communications throughout the application. The Model caches named references to Proxies, which expose an API for manipulating the Data Model (including data retrieved from remote services). The View primarily caches named references to Mediators, which adapt and steward the View Components that make up the user interface. The Controller maintains named mappings to Command classes, which are stateless, and only created when needed. The Façade initializes and caches the Core actors (Model, View and Controller), and provides a single place to access all of their public methods. AUTHOR: Cliff Hall <[email protected]> LAST MODIFIED: 3/05/2008 Façade and Core The Façade class makes it possible for the Proxies, Mediators and Commands that make up most of our final application to talk to each other in a loosely coupled way, without having to import or work directly with the Core framework actors. When we create a concrete Façade implementation for our application, we are able to use the Core actors ‘out of the box’, incidental to our interaction with the Façade, minimizing the amount of API knowledge the developer needs to have to be successful with the framework. -

Pamela Jennings, 1996 To my Parents ACKNOWLEDGEMENTS First and foremost I want to acknowledge the help, dedication and commitment of my advisor Janet Murray. Her relentless criticism and simultaneous encouragement sharpened both my wit and the focus of my arguments. Jay Bolter gave me the courage to start this project and provided not only lucid intellectual advice, but also a shoulder to lean on and a voice of sanity in the darkest hours of this thesis. Celia Pearce gave me a new appreciation of games and encouraged me to include installation pieces I would have otherwise overlooked.
