In the landscape of 1994, the word "modern" meant something radically different than it does today. Intel had just released the Pentium (P5). RISC architectures (SPARC, MIPS, Alpha, PowerPC) were waging a clock-speed war. And the Unix operating system—born in the 1970s on DEC PDP minicomputers—was undergoing a painful, bloody, yet glorious metamorphosis to survive on these new, complex beasts. complex beasts. : Analysis of tightly-coupled
