This is a great time to be a Flash game developer. Right now, there is no better development tool for small and medium-size games. Flash CS3 Professional (a.k.a. Flash 9) is fast, powerful, and easy to develop with. The key to this is ActionScript 3.0, the great new programming language inside this latest version of Flash. ActionScript 1.0 and 2.0 were often frustrating for game developers. They weren’t fast enough to get key tasks done, and...

First released to the public in 2004 after being developed to support the Basecamp project management application, Ruby on Rails promised nothing less than a revolution in the way web applications are constructed. With a strong grounding in the pragmatic ethic of avoiding repetition, the Rails way of supporting common conventions instead of complex options showed that there was a simpler way to build for the Web, and “ my code is shorter...

If you’re used to huge, overly complex web applications, you’re in for a treat—both Ruby and Rails can do a lot of the code writing for you, creating skeleton applications that you can modify easily. And if you’re new to web programming, you’re also in for a treat because you’re getting started the right way. Ruby is the programming language you’re going to be using, and Rails is the web application framework that will put...

Ruby on Rails? What’s that?” asks my uncle. “You write about this stuff for dummies? You mean those black and yellow books that everyone buys?” “Yes, like the one I’m quoting you in,” I say. “Please check your spelling as you speak.” “I will. But what’s Ruby on Rails? Is it the 6:05 train to Poughkeepsie? Is it the name of an old vaudeville act? Is it a pop singer? A rock band? Is it a rare stone from India? Is it the...

Ruby on Rails has shaken up the web development industry in a huge way—especially when you consider that version 1.0 of Rails was only released in December 2005. The huge waves of enthusiasm for the new framework, originally in weblogs and later in the more traditional media, are probably the reason why this book is in your hands.

There have been many extravagant claims made about Rails. For example, an article in OnLAMP.com1 claimed that “you could develop a web application at least ten times faster with Rails than you could with a typical Java framework...” The article then went on to show how to install Rails and Ruby on a PC and build a working ‘scaffold’ application with virtually no coding. While this is impressive, ‘real’ web developers know that this...

It has been 18 months since I announced the first edition of this book. It was clear before the book came out that Rails would be big, but I don’t think anyone back then realized just how significant this framework would turn out to be. In the year that followed, Rails went from strength to strength. It was used as the basis for any number of new, exciting web sites. Just as significantly, large corporations (many of them household names)...
