Doug Bierer has been writing code since the early 1970s. His first project was a terrain simulator that ran on a Digital Equipment Corporation PDP-8 with 4 K of RAM. Since then, he's written applications for a variety of customers worldwide, in various programming languages, including BASIC, Assembler, PL/I, C, C++, FORTH, Prolog, Pascal, Java, PERL, PHP, and Python. His work with database technology spans a similar range in terms of years and includes Ingres, d:Base, Clipper, FoxBase, r:Base, ObjectVision, Btrieve, Oracle, MySQL, and, of course, MongoDB. Doug runs his own company, unlikelysource, and is also CTO at Foreach Code Factory, being involved in both training (php-cl) and a new cloud services platform (Linux for PHP Cloud Services).
