Unfortunately, despite the best efforts of myself, the technical editor, the copy editor, the line editor, the proofreader, and despite the multiple revisions, errors still occur. This page lists all the errors found in the book since it went to print.
Note: errors are corrected in subsequent printings and therefore your particular copy may not contain all of the following. You may also be experiencing problems not caused by a mistake in the book. If so, you may find the solution to your problem by using the book’s corresponding forum. Significant changes in the technology will be addressed there and you can also find problems and solutions encountered by other readers.
