Another way to go with your sketches is related to the three-panel photographs approach, except here you sketch simple icons that represent the essence of your idea in a basic visual form. For example, as shown on the third Key Point slide on the lower right in Figure 7-12, sketch the innovative three-part strategy as the numbers 1-2-3 in a box, the experienced team as a group of three face symbols, and our clients are so satis ed as a piece of paper with the gure 100% on it. Sketch only the rst and second icons on the second Key Point slide, and only the rst icon on the rst Key Point slide. It would be ne to use the same graphic on the third Key Point slide and on the Call to Action slide sketch a note to differentiate the Call to Action version later by adding animation to that slide only.

An official English language Web site soon followed in late 1999 with the creation of ruby-lang.org (http://www.ruby-lang.org/), which is still Ruby s official English language Web site (see Figures 5-1 and 5-2 for a comparison of the official site between then and now). Ruby failed to catch on with all but a few ardent developers until 2000 and 2001 (with the main Ruby Usenet newsgroup comp.lang.ruby being created in May 2000), and even then the English-speaking Ruby community was tiny. Matz didn t consider this to be important though, and was even surprised that other people found his language useful, having only created it to fit his own way of thinking.

The keys method returns a list of the keys in the dictionary, while iterkeys returns an iterator over the keys.

However, the exposure of Ruby to the larger audience of software developers continued to be low. IBM published an article with a brief overview of Ruby and an interview with Matz in 2000, and the much-revered Dr. Dobb s Journal published an article by Dave Thomas and Andy Hunt with a similar introduction in January 2001. Despite Ruby s obvious power, it appeared as if Python and PHP were going to win the race to become the next Perl as general scripting and Web languages, respectively, up until 2004 (although Ruby was more popular than Python even in 2000). But then everything changed when a young Dane released a tool based upon Ruby that would quickly change the perception of the language in the worldwide development community.

Since 2005 it has become impossible to publish any book or article about Ruby without mentioning Ruby on Rails. Ruby on Rails is a Web application framework that has

As shown here, you build a visual formula out of the icons by sketching a plus sign after the rst icon and an equal sign after the second element. You can also sketch the numbers 1-2-3 or the letters A-B-C alongside each icon to relate that familiar organizational structure to the audience and build the formula 1+2=3 or A+B=C. If your headlines support the concept, create an unexpected formula that will play out in the presentation such as 1+1=11, which will intrigue your audience as they wait to see how you will explain what it means.

propelled the popularity of Ruby outside of Japan from a humble core of avid developers to hundreds of thousands of developers all now interested in using the language. This section examines Ruby on Rails, explains why it s important, and discusses how its presence has changed the whole dynamic of the Ruby ecosystem.

The pop method can be used to get the value corresponding to a given key, and then remove the key-value pair from the dictionary: >>> d = {'x': 1, 'y': 2} >>> d.pop('x') 1 >>> d {'y': 2}

Note An application framework is a set of conventions, structures, and systems that provide an underlying structure to make application development easier. Ruby on Rails is such a framework for Web application development.

I ll be covering Ruby on Rails development in 13, but let s first look at the motivation behind the framework and how it has changed the entire Ruby landscape.
