Many titles include programming code or configuration examples. To optimize the presentation of these elements, view the eBook in single-column, landscape mode and adjust the font size to the smallest setting. In addition to presenting code and configurations in the reflowable text format, we have included images of the code that mimic the presentation found in the print book; therefore, where the reflowable format may compromise the presentation of the code listing, you will see a Click here to view code image link.

First and foremost, a big thanks to my friends and family
for supporting me throughout this process. You pushed me
to start this book and then begged me to finish it!

To my late father, who taught me to inspire
and entertain others with my talent and
wild imagination: I am forever your biggest fan.

Last, to the love of my life and best friend, Jessica:
without you this book would have been just
more dust in the wind of my ideas. Thank you for
all of your guidance and wisdom, and for believing
that I could accomplish this. I love you always and forever.

Matthew Johnson

For my wonderful wife, who brought me tea
whenever I locked myself in my office to write
and tolerated being temporarily widowed by this book.
