Dan Pilone is a Software Architect for Vangent, Inc., and has led software development teams for the Naval Research Laboratory, UPS, Hughes, and NASA. He's taught graduate and undergraduate Software Engineering at Catholic University in Washington, D.C.

Dan's previous Head First books are Head First Software Development and Head First Algebra, so he's used to them being a little out of the ordinary, but this is the first book to involve bounty hunters. Even scarier was watching Tracey shift to become a night owl and Apple fan-girl to get this book done.

Dan's degree is in Computer Science with a minor in Mathematics from Virginia Tech and he is one of the instructors for the O'Reilly iPhone Development Workshop.

Tracey Pilone would first like to thank her co-author and husband for sharing another book and being relentless in his willingness to stay up late to get things right.

She is a freelance technical writer who supports mission planning and RF analysis software for the Navy, and is the author of Head First Algebra.

Before becoming a writer, she spent several years working as a construction manager on large commercial construction sites around Washington, D.C. There she was part of a team responsible for coordinating the design and construction of office buildings, using engineering and management skills that somehow all came in handy writing Head First books.

She has a Civil Engineering degree from Virginia Tech, holds a Professional Engineer's License, and received a Masters of Education from the University of Virginia.
