Caitrin McCullough's first name really doesn't have an L in it, honest. She got her start in publishing working on O'Reilly's animal books before jumping ship to the Head First division, where she manages the online presence of this dymanic series. When she's not taking web programming courses or hunting down broken links, she's either hiking up a mountain or sitting at home with her two cats (depending on the time of day). She's been playing acoustic bass since fifth grade, when she was the only person in her class tall enough to play one. She also studies historical rapier combat.
