How-To's
How-To's, shown in Figure 6.6, attempt to answer “How do I…?” questions for new developers. The informa-
tion is of variable quality and often leaves out key facts. For example, the Graphics & Animation Coding How-
To document explains how to obtain a graphics context for 2D drawing, but doesn't include full sample code
and doesn't explain what a graphics context is or why you might need one. Experienced developers can use
how-to's as memory joggers. New developers are likely to find they need extra help to understand the jargon
and concepts described in these documents.
FIGURE 6.6
It's a good idea to be slightly skeptical of the information in the how-to's. For example, you quickly discover that
there are easier ways to find out which version of SDK is installed than are described here.
