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.

A subgroup of the Unix family is the Berkeley Software Distribution family, which includes FreeBSD, NetBSD, and OpenBSD. These operating systems are most commonly found on webservers, although they can also function as a personal computer OS. The Internet owes much of its existence to
