37signals (http://www37signalscom/), a successful Web software company, was founded in 1999 initially as a Web design agency that promoted the use of clean, fast, and functional designs over the gee-whiz Flash-based Web sites that were popular at the time With only two cofounders running the entire company, they quickly realized they needed some tools to help them run their business efficiently They tried some off-the-shelf software but found nothing that matched their needs, and found most solutions to be bloated and complex They felt their attitude toward Web design should also be applied to applications, and in mid-2003 decided to develop their own project management tool As designers, rather than coders, 37signals turned to the services of David Heinemeier Hansson, a student in Copenhagen, Denmark, to develop their project management application.

Rather than use the then-common tools such as Perl or PHP Hansson was con, vinced that 37signals could develop the application far more quickly and completely by using Ruby Previously a PHP coder, Hansson was beginning to feel the pain of using PHP for large Web application development and felt a new direction should be sought As development on the nascent application (entitled Basecamp ) progressed, the team members showed it to others in the industry and quickly realized from the responses they heard that they should release the application to the public rather than keep it for their own use With a successful public release of Basecamp in February 2004 only about four months after beginning the project the development methodology adopted by 37signals and Hansson was proven, and 37signals began a rapid transition into an application development company, with Hansson eventually becoming a partner at the company.

If you plan to use video, audio, or motion graphics in your presentation, these forms of media stand out so signi cantly from the even pacing of your presentation that you want to use them carefully and strategically. Before you use them, consider the research study described in 2 that found when you remove extraneous information from a multimedia presentation, you increase learning. Remember, in Act II it s all about the hierarchy in your storyboard, and your measure of success is if your audience can recall and apply the information on your Key Point slides. If you can use video, sound, or motion graphics to illustrate the Key Point headlines, go ahead and sketch these elements on the Key Point slides. Be very careful about using these types of media in another part of the presentation if you don t use them on your Key Point slides you would be unsuccessful in your presentation if the audience remembered your trendy video on the Detail slides but not the message of your Key Point slides.

The popitem method is similar to list.pop. Unlike list.pop, however, popitem pops off a random item because dictionaries don t have a last element or any order whatsoever. This may be very useful if you want to remove and process the items one by one in an efficient way (without retrieving a list of the keys first): >>> d {'url': 'http://www.python.org', 'spam': 0, 'title': 'Python Web Site'} >>> d.popitem() ('url', 'http://www.python.org') >>> d {'spam': 0, 'title': 'Python Web Site'} Although popitem is similar to the list method pop, there is no dictionary equivalent of append. Because dictionaries have no order, such a method wouldn t make any sense.

Ruby proved to be the silver bullet that powered the rapid development of Basecamp Hansson used Ruby s object orientation and reflection features to build a framework that made developing database-driven Web applications easier than ever before This framework became known as Ruby on Rails, and was first released to the public in.

July 2004. 37signals continued to develop new products quickly using the power of the new framework. Like Ruby itself, the Ruby on Rails framework didn t immediately experience an explosion of popularity, but found a small number of ardent fans who began to realize its power and, in many cases, wished to replicate 37signals success.

Earlier in this chapter, you learned about displaying a blank screen for the Setting slide while you tell an anecdote, creating a sense of surprise after the Title slide, when the audience expects to see bullet points on screen. Now that you ve sketched a number of other slides, consider fading to black to emphasize the Key Point slides. Visuals projected on a screen can be spellbinding, but when you break that spell by blacking out the screen, you focus the audience s attention completely on you and your ideas at a speci c moment. This creates an abrupt shift in the presentation with dramatic effect that works well to emphasize your three Key Point slides.
