Plan 9 from Bell Labs

By the mid 1980 s, the trend in computing was away from large centralized time-shared computers towards networks of smaller, personal machines, typically UNIX worksta­ tions . People had grown weary of overloaded, bureaucratic timesharing machines and were eager to move to small, self-maintained systems, even if that meant a net loss in computing power. As microcomputers became faster, even that loss was recovered, and this style of computing remains popular today.
