About the Authors Brad Bulger can remember when computers were as big as refrigerators and old- timers would come into the machine room and call them “mini.” After working for several companies that no longer exist, he is now a member of The Madfish Group ( http://www.madfishgroup.com ), where he builds Web sites for money. He would still like to know when the future is going to get here but has a sneaking suspicion he already knows. Jay Greenspan is a New York–based writer, editor, and technical consultant. He has contributed to sites run by Apple Computer and Wired Digital, and is author of MySQL Weekend Crash Course. He runs Trans-City Productions, Inc. ( http://www. trans-city.com ), a firm that provides editorial services to high-tech companies. David Wall is a freelance technical consultant, lecturer, and writer. He specializes in Linux/Apache/MySQL/PHP (LAMP) servers and in Voice over IP technologies from IBM and Cisco Systems. His consultancy, David Wall Enterprises ( http:// www.davidwall.com ), has offices in Washington, D.C., and Sydney.
