The technical review team

Rich Rosen is one of the co-authors of Mac OS X for Unix Geeks. He also collaborated with Leon Shklar on Web Application Architecture: Principles, Protocols & Practices, a textbook on advanced web application development. He began his career eons ago at Bell Labs, where his work with relational databases, Unix, and the Internet prepared him well for the world of web technology. He lives in New Jersey with his wife, Celia, whose singing provides a sweet counterpoint to the cacophony he produces in his Mac-based home recording studio.

Sean Murphy has been a Cocoa aficionado for almost 10 years, contributes to open source projects such as Camino, and works as an independent iOS designer and developer. He lives in Pennsylvania with his best friends—a fiancÉe, horses, dogs, and cats—and seriously loves hiking, hockey, and nature.
