Those little pictures in the margins of the book emphasize a point to remember, a danger to be aware of, or information that we think you may find helpful. This book uses the following icons:
Tips are little bits of information that you may find useful — procedures that aren't necessarily obvious to the casual user or beginner.
When your mother warned you, “Don't touch that pan — it's hot!”, but you touched it anyway, you discovered the meaning of “Ouch!” We use this icon for situations like that. Out of curiosity, you may very well touch the hot pan, but you can't say that we didn't warn you!
All geeky stuff goes here. We use this icon when talking about technical information. You can skip it, but we think you'll find some great nuggets of information next to these icons. You may even surprise yourself and find you enjoy them. Be careful — you may turn into a geek overnight!
When you see this icon, brand the text next to it into your brain so that you remember whatever it was we thought you should remember.
