Linus Torvalds Institute. Linus Torvalds is married to Tove Torvalds (née Monni)—a six-time Finnish national karate champion—whom he first met in late 1993. Linus was running introductory computer laboratory exercises for students and instructed the course attendees to send him an e-mail as a test, to which Tove responded with an e-mail asking for a date. Tove and Linus were later married and have three daughters, Patricia Miranda (born 1996), Daniela Yolanda (born 1998), and Celeste Amanda (born 2000), two of whom were born in the United States. The Linux kernel's "reboot" system call accepts their dates of birth (written in hexadecimal)
Operating system Digital Equipment Corporation developed many operating systems for its various computer lines, including TOPS-10 and TOPS-20 time sharing systems for the 36-bit PDP-10 class systems. Before the widespread use of UNIX, TOPS-10 was a particularly popular system in universities, and in the early ARPANET community. RT-11 was a single-user real-time OS for the PDP-11 class minicomputer, and RSX-11 was the corresponding multi-user OS. From the late 1960s through the late 1970s, several hardware capabilities evolved that allowed similar or ported software to run on more than one system. Early systems had utilized microprogramming to implement features on their systems in
