Chris Ullman is a freelance Web developer and technical author who has spent many years stewing in ASP/ASP.NET, like a teabag left too long in the pot. Coming from a Computer Science background, he started initially as a UNIX/Linux guru, who gravitated towards MS technologies during the summer of ASP (1997). He cut his teeth on Wrox Press ASP guides, and since then he has written over 20 books, most notably as lead author for Wrox's bestselling Beginning ASP/ASP.NET series, and has contributed chapters to books on PHP, ColdFusion, JavaScript, Web Services, C#, XML and other Internet-related technologies too esoteric to mention, now swallowed up in the quicksands of the dot.com boom.
Quitting Wrox as a full-time employee in August 2001, he branched out into VB6 programming and ASP development, maintaining a multitude of sites from http://www.cuasp.co.co.uk, his "work" site, to http://www.atomicwise.com, a selection of his writings on music and art. He now divides his time between being a human punchbag for his 29-month-old son Nye, composing electronic sounds on bits of dilapidated old keyboards for his music project Open E, and tutoring his cats in the art of peaceful co-existence, and not violently mugging each other on the stairs.
Chris Ullman contributed Chapters 1, 14, 15, 16, 17, and Appendix E to this book.

John Kauffman was born in Philadelphia, the son of a chemist and a nurse. He received his degrees from The Pennsylvania State University, the colleges of Science and Agriculture. His early research was for Hershey foods in the genetics of the chocolate tree and the molecular biology of chocolate production. Subsequently, he moved to the Rockefeller University, where he cloned and sequenced DNA regions that control the day and night cycles of plants.
Since 1997, John has written ten books, six of which have been on the Amazon Computer Best Seller List. His specialty is programming Web front-ends for enterprise-level databases.
In his spare time, John is an avid sailor and youth sailing coach. He represented the USA in the sailing World Championship of 1985 and assisted the Olympic teams of Belgium and China in 1996. He also enjoys jazz music and drumming and manages to read the New Yorker from cover-to-cover each week.
