Within a minute or so, many hundreds of gems and descriptions should go flying past (do allow a couple minutes though, as RubyForge can often be extremely busy). Wading through such a list is impractical for most purposes, but generally you ll be aware of which gem you want to install before you get to this stage. People on the Internet will recommend gems, or you ll be asked to install a particular gem by this book or another tutorial. However, if you wish to browse, the best way to do so is to visit http:// rubyforge.org/, the home for the RubyGems repository. RubyForge features search tools and more information about each gem in the repository. Alternatively, you can use the search features offered by the gem program directly, like so:

If you are a decent storyboard sketcher, consider something completely different and present your PowerPoint slides with only the headlines and no graphics added at all. When you present live, use a Tablet PC to sketch a graphic to illustrate each headline as you go along. It will be a deeply engaging and interesting experience for the audience, plus you can save the sketches you made with the PowerPoint le and send the illustrated le to everyone who attended.

*** REMOTE GEMS *** calibre-classinherit (2.1.0) Provides class-level inheritance for mixin modules. calibre-classmethods (2.0.0, 1.0.0) Provides class-level inheritance for included modules.

Sometimes you may want to create Python code on the fly and execute it as a statement or evaluate it as an expression. This may border on dark magic at times consider yourself warned.

Learning can be a fun activity in its own right, but merely reading about something won t make you an expert at it. I ve read a few cookbooks, but this doesn t seem to improve my cooking when I attempt it from time to time. The missing ingredient is experimentation and testing, as without these your efforts are academic, at best. With this in mind, it s essential to get into the mood of experimenting and testing from day one of using Ruby. Throughout the book I ll ask you to try out different blocks of code and to play with them to see if you get the results you want. You ll occasionally surprise yourself, sometimes chase your code into dead ends, and often want to pull out your hair (if you have any, of course!). Whatever happens, all good programmers learn from experimentation, and you can only master a language and programming concepts by experimenting as you go along. Trust me, it s fun! This book will lead you through a forest of code and concepts, but without testing and proving the code is correct to yourself, you can quickly become lost. Use irb and the

If you re feeling particularly ambitious, try developing a single illustration across the entire presentation. You will have to plan this carefully in the story template, but the basic idea is that you introduce one piece of the graphic, one slide at a time, as you verbally explain each piece, until everything in the illustration comes together into a single graphic at the end of the presentation. This technique literally helps you explain the big picture to your audience.

other tools I ll cover frequently and experiment with the code as much as possible so that the knowledge will stick. Type in the following code at your irb prompt and press Enter:
