Conventions
The following is a list of the typographical conventions used in this
book:
Italics
Used to indicate URLs, filenames, filename extensions, directory
names, and folder names. For example, a path in the filesystem will
appear as C:\Program Files.
Constant width
Used to show code examples, the contents of files, and console
output, as well as the names of variables, commands, and other code
excerpts.
Constant width bold
Used to highlight portions of code, typically new additions to old
code, as well as to show text that should be typed literally.
Constant width italic
Used in code examples and tables to show sample text to be replaced
with your own values.
You should pay special attention to notes set apart from the text
with the following icons:

This is a tip, suggestion, or general note. It contains useful
supplementary information about the topic at hand.
|

|
This is a warning or note of caution, often indicating that your
money or your privacy might be at risk.

The thermometer icons, found next to each hack, indicate the relative
complexity of the hack:
