Passage: Peterson grew up in Santa Barbara, California. As a son of British mother and an American father, his paternal ancestors emigrated to Santa Barbara from Spain. Peterson was educated at public schools in the Santa Barbara area. He was raised next door to the director of the University of California, Santa Barbara computer laboratory, who introduced him to computer programming at an early age in 1978.In 2017, Peterson's life story was featured in a book written by motivational speaker Brian Tracy about entrepreneurs. Peterson spent much of his early childhood remotely connecting to the UCSB mainframe computers via terminal and modem. Through early access to technology, Peterson learned to make his own Unix and VMS based software applications on the campus PDP-11 and DEC VAX computer systems. In the early years of computing, the largely technical science of programming was a pastime overrun by the likes of college professors and engineers. To fit in, Peterson reportedly maintained an identity for login on the MIT Artificial Intelligence Laboratory PDP-10, where he was known by his peers as "Dr. Jeffrey Peterson", at the age of eleven.In 1981, Peterson landed his first job, as a troubleshooter for a software company focused on Commodore computers. In 1983, he worked as a product tester for vintage hardware manufacturer LOBO Systems. During the mid-1980s, Peterson focused on the development of software for freely distributed bulletin board system and multi-user dungeon gaming applications. He was known among his colleagues as an expert at implementing customized kernel-level multitasking solutions, who regularly pushed early hardware beyond traditional limits. Peterson, already a seasoned assembly and C language developer in his early years, contributed heavily to the emerging F/OSS programming communities of the 1980s. He has published numerous texts, including articles on multiprocessing, quasi-empirical methods, and artificial intelligence.Peterson was ridiculed about his early programming years in a satirical...
