The creative work involved in creating concept art for games is one of the most rewarding jobs that an artist can have. In fact, it is possibly the most creative job in the entire game industry. Concept artists have the opportunity to visualize things that have never been seen before. They create the visual design of games. It is a huge responsibility and yet one of the most enjoyable experiences an artist can have.

When an artist creates a game, there is much more going on than in almost any other type of art anywhere. In a game, the artist is creating a self-contained world in which characters can interact with each other and things can happen. Unlike painting a picture, creating art for a game is about as close to intelligent art creation as an artist can get. It is like creating a world, and it is exciting to think about.

Concept art is the foundation of game creation. Game development relies on the concept art to give direction to the development team. The concept artist supplies the vision for the game. Without the concept art, there is a good chance that there will be miscommunication in the development process. The concept artist is the one who visualizes the game and then gives that vision to the rest of the development team.

This book is about creating game concept art. It covers a vast array of art required in the conceptual stage of game development. It is a beginning book, so it takes a basic look at creating game concept art. You do not need to have any game art development experience to read this book.

This book contains several step-by-step examples for you. These examples are designed to help you understand how the art is created. You are encouraged to follow the examples to get a feel for the project. After trying the examples in the book, you should try a few projects of your own.

Creating game concept art is fun. This book should help you on your way to a wonderful experience in creativity.

This book is a revised, updated and expanded edition of Drupal 5 Themes, written specifically for Drupal 6. The book will show you techniques and tools to help you improve the look and feel of any Drupal 6-powered website.

Starting from the basics of theme setup and configuration, you will learn about the Drupal theming architecture and the PHPTemplate engine, and then move on to modifying existing themes and building new themes from scratch. You will find out about tools to make your theme development easier, and also find invaluable information about under-documented elements of the theming system.

What you will learn from this book?

• Learn about the Drupal 6 Theming Architecture
• Find and install new themes
• Get the most from Drupal's theme configuration system
• Create a new theme from scratch

JBoss Tools consist of the best Java frameworks and technologies placed together under the same "roof". Discovering JBoss Tools is like exploring a cave; at first everything seems unknown and complicated, but once you become familiar with the main features of the Tools, you will start to feel at home.

This is the first book in the market on JBoss Tools, waiting to assist you to throw away all the tiny, dedicated tools you have used earlier, thus helping you to reduce the time you spend on developing a Java application. This book will explore the tools that will help you to build Hibernate, Seam, JSF, Struts, Web Services, jBPM, ESB, and so on and show you how to use them through screenshots, examples, and source code. JBoss Tools comes with a set of dedicated wizards, generators, editors, reverse engineering capabilities, configuration files, templates, syntax highlighting, and more for each of these technologies. Just choose the technologies, and JBoss Tools will glue them together in amazing Java web applications.

This book will show you how to develop a set of Java projects using a variety of technologies and scenarios. Everything is described through JBoss Tools "eyes". After we settle the project (or scenario) that will be developed, we configure the proper environment for the current tool (the selected projects cover the main components of a web application, with regard to the backstage technology). We continue by exploring the tool to accomplish our tasks and develop the project's components. A cocktail of images, theoretical aspects, source code, and step-by-step examples will offer you a complete insight into every tool.

At the end, we deploy and test the project. In addition, every chapter is rich with pure notions about the underlying technology, which will initiate into you or remind you of the basic aspects of it. It will also show you complete and functional applications, and get you familiar with the main aspects of every tool. By the end you will have enough information to successfully handle your own projects with JBoss Tools.

No matter how much (or how little) experience they have, developers of all levels will benefit as their use of JBoss Tools is directly proportional to the complexity of their application. Since JBoss Tools covers all levels of experience, you can use it at your own level for your own applications, without involving unnecessary features. All you need is to be familiar with the Eclipse environment and Java core, and to have some expertise in the technology for which you want to use the JBoss Tools. Basic expertise for each technology is provided in the book, but for more complete and detailed aspects you should read dedicated specifications, tutorials, and articles.

JavaScript: It's not just for calculators and image rollovers.

Drupal 6 is loaded with new features, and not all of them are necessarily implemented in PHP. This unique book, for web designers and developers, will take you through what can be done with JavaScript (and especially with jQuery) in Drupal 6.

With the combination of the powerhouse jQuery library with its own robust set of JavaScript tools, Drupal 6 comes with a pre-packaged killer JavaScript environment. Cross-platform by nature, it provides all of the tools necessary to create powerful AJAX-enabled scripts, gorgeous visual effects, and view-enhancing behaviors. In addition, Drupal developers have ported some of its most powerful PHP tools - like a theming engine and support for localization and language translation - to JavaScript, making it possible to write simple scripts where once only complex PHP code could be used.

This book gives you the keys to the toolbox, showing you how to use Drupal's JavaScript libraries to make your modules and themes more dynamic, interactive and responsive, and add effects to make your Drupal site explode into life!

If you've dipped your toe in the water of theme or module development with Drupal 6, this is the book you want to make the look and behavior of your work something special. With it's project-based approach, this book is carefully constructed to guide you from how JavaScript fits into the overall Drupal architecture through to making you a master of the jQuery library in the world of Drupal themes and modules.

What you will learn from this book?

• An introduction to JavaScript in Drupal 6
• The basics of the jQuery library
• Creating JavaScript-enabled themes
• Manipulating a page on the fly with jQuery
• Authoring simple PHPTemplate files designed to maximize scripting potential
• Using jQuery to add effects in Drupal 6
• Working with Drupal 6 behaviors
• Adding AJAX to modules
• Using Drupal's localization and language translation engine in your JavaScript
• Theming on the client-side with Drupal's JavaScript theme engine
• Building better forms
• Working with Drupal 6's JavaScript library
• Writing portable JavaScript tools as Drupal modules

Approach

This book focuses on teaching by example. Chapters are packed with example code, providing hands-on examples you can play with and then release to your own Drupal sites. By introducing short projects interspersed with discussion, the pace is rapid yet practical.

Who this book is written for?

This book is for web designers and developers who want to add JavaScript elements to Drupal themes or modules to create more flexible and responsive user interfaces.

You are expected to know about the basic operation of Drupal, and be familiar with the concept of theming and modules in Drupal. No experience of creating themes or modules is required.

You will need to know the basics of client-side web development; this means HTML, CSS, but also have a rudimentary grasp of the syntax of JavaScript. Familiarity with PHP programming will be an advantage, since we will be writing PHPTemplate files and (at the end) creating Drupal modules. However, the PHP is covered thoroughly enough that even the PHP neophyte will not find the text too demanding. The book also covers the jQuery JavaScript library and its use in Drupal, but no knowledge of jQuery is expected - you will learn everything you need in this book.

SOA is about architecture, not products and SOA enables you to create better business processes faster than ever. While BizTalk Server 2009 is a powerful tool, by itself it cannot deliver long-lasting, agile solutions unless we actively apply tried and tested service-oriented principles.

The current BizTalk Server books are all for the 2006 version and none of them specifically looks at how to map service-oriented principles and patterns to the BizTalk product. That's where this book fits in. In this book, we specifically investigate how to design and build service-oriented solutions using BizTalk Server 2009 as the host platform.

This book extends your existing BizTalk knowledge to apply service-oriented thinking to classic BizTalk scenarios. We look at how to build the most reusable, flexible, and loosely-coupled solutions possible in the BizTalk environment. Along the way, we dive deeply into BizTalk Server's integration with Windows Communication Foundation, and see how to take advantage of the latest updates to the Microsoft platform. Chock full of dozens of demonstrations, this book walks through design considerations, development options, and strategies for maintaining production solutions.

What you will learn from this book?

• Understand how the core aspects of SOA apply to specific BizTalk components
• Consume and expose WCF services from BizTalk solutions
• Build schemas that enable efficient data sharing
• Exploit asynchronous programming models and implement client callbacks
• Chain orchestrations together in a loosely coupled way
• See one solution for complex event processing in a BizTalk environment
• Efficiently version BizTalk artifacts
• Get to know Microsoft UDDI v3 services and how to add and reference services in this registry
• Enhance BizTalk solutions with the Microsoft ESB Guidance package
• Utilize the WCF SQL Server Adapter as both a client and a service

Approach

This book takes a hands-on approach to explain and present ways to use BizTalk Server 2009 in a service-oriented fashion. Written much like the author's blog, this book does not direct your every mouse click and keyboard stroke, but rather identifies the problem being solved, and includes the code snippets and screenshots necessary to recreate these solutions yourself.

Who this book is written for?

Targeted at individuals already familiar with BizTalk Server and not those expecting a full tutorial on every aspect of the product, this book is ideal for architects and developers who want to develop the most maintainable BizTalk Server solutions possible. This is the first book available on BizTalk Server 2009 and covers all relevant features for those of you designing a BizTalk business solution.

Solid/Liquid Separation (SLS) is a cross-sectional unit operation which is ubiquitous in all sectors of the process industry as well as in environmental protection. Hence process engineers and experts of different fields are frequently confronted with specific Solid/Liquid-Separation terms and definitions they do not use for their daily business. Very often they require a reference book with explanations and interpretations that are readily understandable.

To fulfil this need, BOKELA has assembled a team of authors consisting of academic and industrial experts to compile the 'Solid/Liquid Separation Lexicon'. This work gives a comprehensive survey of the definitions, terminology and concepts introduced by the Karlsruhe (Germany) School for Solid/Liquid-Separation Science. These terms are widely used as a standard and are now largely accepted in the scientific community.

Developing powerful web applications with clean, manageable code makes the maintenance process much easier. Aspect-Oriented Programming (AOP) is the easiest and quickest way to achieve such results. Spring is the only Java framework to offer AOP features. The combined power of Spring and AOP gives a powerful and flexible platform to develop and maintain feature-rich web applications quickly.

This book will help you to write clean, manageable code for your Java applications quickly, utilizing the combined power of Spring and AOP. You will master the concepts of AOP by developing several real-life AOP-based applications with the Spring Framework, implementing the basic components of Spring AOP: Advice, Joinpoint, Pointcut, and Advisor.

This book will teach you everything you need to know to use AOP with Spring. It starts by explaining the AOP features of Spring and then moves ahead with configuring Spring AOP and using its core classes, with lot of examples. It moves on to explain the AspectJ support in Spring. Then you will develop a three-layered example web application designed with Domain-Driven Design (DDD) and built with Test-Driven Development methodology using the full potential of AOP for security, concurrency, caching, and transactions.

What you will learn from this book?

• Learn how Aspect-Oriented Programming can support Object-Oriented Programming to solve problems in the implementation phase
• Write clean and concise code by implementing concurrency control in cross-cutting functionalities to manage code easily and create applications quickly
• Realize a dynamic proxy with JDK, by implementing an interface that manages invocations
• Realize the structural behavior of the pattern proxy design pattern by applying the crosscutting concerns of security, logging, and transactionality to specific Joinpoints
• Simplify applying Advices through using AspectJ annotations
• Develop better applications by handling important functionalities such as transaction management, application logging, exception management, and layout
• Learn how the AOP enabled by the Spring Framework and Inversion of Control (IoC), can help you to remove the implementation compromises in applications

Approach

Employing a comprehensive tutorial-based approach, this easy-to-follow book shows the reader various means of using AOP with Spring in a real-world scenario. Clear step-by-step instructions ensure that you will not get lost in the new world of AOP and Spring.

Who this book is written for?

If you are a Java software architect, engineer, or developer and want to be able to write applications in a more modular and concise way by using Spring, then you need this book. Readers need basic knowledge of Spring and its configuration.

What do Wayne Gretzky and thermodynamics have in common? A lot more than you might think. The game the National Hockey League calls " the coolest game on earth" is also a fast-paced, dynamic display of physics in action.

In The Physics of Hockey, physicist and amateur hockey player Alain Haché examines some of the physical principles behind the world's most popular winter team sport. What makes ice so slippery you can skate on it? How can you skate backwards most rapidly? How can physics improve your slapshot? Why do some collisions cause injuries but not others? How does a Zamboni work? And how do you prepare a pure, smooth ice surface in Dallas when it's 90 degrees outside and there are twenty thousand people inside?

This is physics by a hockey fan for the hockey fan. Haché investigates the properties of the ice surface, the science of skating and of skates, the odds of winning and losing streaks, and the principles behind shooting, hitting, and goaltending. Touching on topics such as solid-state physics, statistical physics elasticity, probability, thermodynamics, and mechanics, Haché uses science to enhance our appreciation and understanding of the game. The book is illustrated with photos and graphs and punctuated with anecdotes to show how famous players, past and present, are really physicists on skates.

A thought-provoking, fun, and gentle introduction to some basic issues in physics, The Physics of Hockey is a truly unique book worthy of the shelf of every hockey fan and physics enthusiast.

If you think computer security has improved in recent years, The Myths of Security will shake you out of your complacency. Longtime security professional John Viega, formerly Chief Security Architect at McAfee, reports on the sorry state of the industry, and offers concrete suggestions for professionals and individuals confronting the issue. Why is security so bad? With many more people online than just a few years ago, there are more attackers -- and they're truly motivated. Attacks are sophisticated, subtle, and harder to detect than ever. But, as Viega notes, few people take the time to understand the situation and protect themselves accordingly. This book tells you:

Why it's easier for bad guys to "own" your computer than you think Why anti-virus software doesn't work well -- and one simple way to fix it Whether Apple OS X is more secure than Windows What Windows needs to do better How to make strong authentication pervasive Why patch management is so bad Whether there's anything you can do about identity theft Five easy steps for fixing application security, and more

Provocative, insightful, and always controversial, The Myths of Security not only addresses IT professionals who deal with security issues, but also speaks to Mac and PC users who spend time online.
