Steve's been programming on the Internet before it was even called the Internet, and he finds Perl the ideal CGI tool. Steve has written on many programming topics (he's at work now on his 48th book), and has been a contributing editor at PC Magazine.
Besides writing, he has a Ph.D. in physics from Cornell University, where he was on the faculty for ten years. He's also been on the faculty at MIT, where he got his undergraduate degree. These days, Steve and Nancy divide their time between residences in the Austrian Alps, Tanglewood, and a small, picturesque town on the New England coast.
