Thanks to Courtney Nash, who supported our efforts to think beyond the
conventional curriciulum and took time to wonder with us about what the
learner’s brain wanted to know next. She consistently pushed us toward the
bigger picture—and it’s a much better book for that. Extra props to her for
googling our odd British phrases and sayings to find U.S.-friendly translations!
And to Brett McLaughlin, who started us off on this book, and
provided some really kick-ass training on the Head First way
and why it rules the world. Also to the folk who rocked training
in Boston 2008 and added so much to the experience: Lou Barr,
Elizabeth Robson, John Guenin, Edward Ocampo-Gooding, Aaron
Glimme, Dave Sussman, Les Hardin, David Flatley and Tracey
Pilone. (We heard everybody named in person buys a copy.…)
Our artworker and brain-fuzz-detector:
To Badger (Jennie Routley), for the initial “you should write one
of those…I could do the pictures!”, through to many hours of
genius graphics work. Also for never holding back on telling us
that some algebra was “disgusting” when we’d crossed the line.
The O’Reilly team:
To Karen Shaner, who handled the tech-review process, and
provided a pep talk when the comments first started coming. To our production
editor, Rachel Monaghan, for being patient about the fact that we mistyped “Length” eight times in
one chapter. To Lou Barr, for her genius Head First template. And to Scott DeLugan and Sanders
Kleinfeld, for once again going above and beyond to get the book out.
Lindsey’s friends and family:
To Helen, for understanding that when I say, “I’ll be there in a minute…I’m almost done…”, it’s an
expression of hope and not reality. And for accommodating a year of lost weekends and working-on-
vacation, and never, ever being intolerant of yet another conversation about triangles. And to Joe—my
brilliant, dyspraxic stepson—for being our “learning differences” guinea pig.
Dawn’s friends and family:
Work on this book would have been lot harder without my amazing support network of family and
friends. Special thanks go to David, Mum and Dad, Carl, Steve, Gill, and Paul. I’ve truly appreciated
all your support and encouragement.
And finally: To Bert Bates and Kathy Sierra, for creating the series that changed our lives.
