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.

EPOC (operating system) system to drive their next generation of devices. First, however, they needed to engineer a 16-bit single-board computer—something that was extremely difficult at the time. They codenamed the project "SIBO", for "single-board organiser" or "sixteen-bit organiser". To develop the SIBO hardware and software, they needed samples of the 16-bit microprocessors they would be programming; but it took more than a year to secure the chips, which caused a significant delay. By 1987, development of EPOC was underway: It was a single-user, preemptive multitasking operating system designed to run in read-only memory (ROM). The operating system and its programmes were written
