Warren Gay has been an electronics enthusiast since childhood and often drags discarded TV sets home after school. In high school, he learned to program the IBM-1130 and then pursued a career in software development at Ryerson Polytechnical in Toronto. Since then, he has worked professionally for over 30 years, mainly in C/C++, under Unix and Linux. Meanwhile, the love of electronics has never faded since the early creation of his home-brewed Intel 8008 system in the 1970s to the present-day projects employing the Raspberry Pi. Warren also holds an advanced amateur radio license and was able to work the Mir space station (U2MIR) using packet radio in August 1991. He's authored other books, including Sams Teach Yourself Linux in 24 Hours, Linux Socket Programming by Example, and Advanced Unix Programming.
