Chris Ullman is a Computer Science graduate who came to Wrox five years ago, when 14.4 modems were the hottest Internet technology and Netscape Navigator 2.0 was a groundbreaking innovation. Since then he's applied his knowledge of HTML, server-side web technologies, Java, and Visual Basic to developing, editing, and authoring books. When not trying to reconstruct the guts of his own PC or trying to write extra chapters in a hurry, he can be found either playing keyboards in psychedelic band, The Bee men, tutoring his cats in the way of eating peacefully from their own food bowl and not the one next to theirs, or hoping against hope that this is the year his favorite soccer team, Birmingham City, can manage to end their exile from the Premier League.
Jon Blank has been a part of the Linux world since before "Linux" was a buzzword, and has been programming (much to the detriment of his social life) in various languages for the better part of his life. He came to the PHP world by way of Perl, and came to Perl by way of The Web Union, an experimental Web hosting provider for students and non-profit organizations that he runs in his spare time. He currently lives in the New York City area, where he is trying to craft a stable career in a field where tempting offers are always around the corner. He doesn't think he'll succeed.
Jon's interests include online role-playing, vintage computers and video games, and graphics arts, as well as many sorts of programming. His primary focus as a programmer is on automation – convincing the computer to do the sort of boring and/or repetitive work that only a computer can stand.
