You could copy this example to many different Linux or OS X machines, for example, and it would work on the majority (env is not universal). If this script were called test.rb and located in the current working directory, you could simply run it from a command line, like so:

Note On most Unix-like operating systems, as well as adding a shebang line, it s necessary to make the

A second possible outcome is that your audience remembered perhaps the bullet points on slides 12 and 33 and the diagram on slide 26 but that s all they remembered. In this scenario, they remember only bits and pieces of the presentation because they experienced fragmented learning (middle right). In fragmented learning, the audience members

Note When you count or number things in your daily life, you probably start counting from 1. The numbering

Naturally, if you copied the script elsewhere (/usr/bin, for example), you could access it directly:

Or if the script s location is in the path, it s even easier:

Whereas shebang lines are used on Unix-like operating systems, Windows users are more familiar with file extensions (such as DOC, EXE, JPG, MP3, or TXT) dictating how a file is processed. If you use My Computer or Windows Explorer to find a folder containing a Ruby file, the file might or might not already be associated with the Ruby interpreter (depending on which Ruby package you installed). Alternatively, Ruby files might be associated with your text editor. In any case, if you want to be able to double-click Ruby files in Windows and have them run directly as regular Ruby programs, you can do this by changing the default action for files with an extension of RB (or any other arbitrary extension you wish to use). The easiest way to set an association is to right-click the icon representing a Ruby file and choose the Open With (or Open, if it s currently not associated with any program) option from the menu. Associate the program with the ruby.exe Ruby interpreter on your computer, and check the Always use the selected program to open this kind of file option. This will cause Ruby files to be executed directly by the Ruby interpreter in future.

scheme used in Python may seem odd, but it is actually quite natural. One of the reasons for this, as you see later in the chapter, is that you can also count from the end: The last item of a sequence is numbered 1, the next-to-last 2, and so forth. That means you can count forward or backward from the first element, which lies at the beginning, or zero. Trust me, you get used to it.

remember at least some things; but from a presenter s perspective, you have no control over what they learned because the fragments could be any pieces of information among many, and you don t know which ones. The third possible outcome is that the audience remembered exactly what the presenter intended they experienced meaningful learning (lower right). Meaningful learning is what any group wants to achieve in their time together the people in the audience understand what the presenter intended, and they are able to apply the information after the meeting. Audiences routinely report that PowerPoint presentations today are Forgettable! and What s the point It s rare to hear an audience and a presenter agree that meaningful learning has occurred. In order to turn the situation around, you literally need to change the shape of the metaphor that guides the way you think about human communication. During a PowerPoint presentation, the memory of an audience member is the critical human element that determines how well new information is received, processed, and stored in the human mind. Researchers who study the mind generally accept that there are three types of human memory, as shown in Figure 2-6. The rst type is sensory memory. Sensory memory is the part of the mind where your audience members brie y store the initial impressions of sights and sounds as they look at and listen to the environment around them. Sensory memory is potentially unlimited in capacity, although sights and sounds might persist in sensory memory for less than a second.
