Acknowledgments
I’d like to thank Christian Hur for working with me on this project. We had a
great experience and worked well together. Christian made this large project a
pleasure, and I greatly appreciate the knowledge, insight, experience, and effort
Christian put forth. Thank you also to Anne Grubb, MC Press Book Editor.
I’d also like to thank my family for their support. A special thanks to Paul for his
love and patience. Writing this book would not have been possible without the
support my family provided. This effort is dedicated in loving memory of my
beloved nephew Brent. We miss him so, and he will always live on in our
memories. Brent was known to say “the sky’s the limit.” These words are so true;
they’re definitely inspirational words to live by. Don’t hesitate to reach for the
sky.
My hope is that this book inspires experienced business developers to feel
comfortable learning Web skills and those new to development to dive in and
learn how to get down to business with Web tools. I’ve been fortunate to have a
career that I enjoy and am very passionate about. I hope this book inspires others
to realize the same career satisfaction.
Laura Ubelhor
First and foremost, I’d like to thank Laura Ubelhor for the opportunity to be a
part of this project and for the learning opportunities she has provided. The
completion of this project could not have been accomplished without her
experience, encouragement, and guidance. I’d also like to thank Anne Grubb for
her support and encouragement. Truly, I’ve been blessed to have worked with
Laura and Anne on this project, and I’ll remain forever thankful.
I cannot express enough thanks to Jim Buck for his encouragement and advice.
Jim has led me to places I never thought I would go, and I offer my sincere
appreciation for introducing me to this project. I’d also like to thank all my
colleagues at Gateway Technical College for their support. A special thanks to all
my students at GTC for giving me inspiration to keep on writing and teaching.
I’d also like to thank my family for their support and encouragement. Most of all,
I want to thank my wife, Kelly, for her incredible heart and invaluable support.
Thanks for giving me the strength to believe in my passion and pursue my
dreams.
