Evi Nemeth
Evi Nemeth (born June 7, 1940 – missing-at-sea June or July, 2013) was an engineer, author, and teacher known for her expertise in computer system administration and networks. She was the lead author of the "bibles" of system administration: "UNIX System Administration Handbook" (1989, 1995, 2000), "Linux Administration Handbook" (2002, 2006), and "UNIX and Linux System Administration Handbook" (2010). Evi Nemeth was known in technology circles as the matriarch of system administration. Nemeth was best known in mathematical circles for originally identifying inadequacies in the "Diffie–Hellman problem", the basis for a large portion of modern network  cryptography. Career. Nemeth received her bachelor's degree in mathematics from Penn State in 1961 and her PhD in mathematics from the University of Waterloo, Ontario in 1971. She taught at Florida Atlantic University and the State University of New York at Utica (SUNY Tech) before joining the computer science department at the University of Colorado Boulder (CU-Boulder) in 1980. She served as manager of the college's computing facility from 1982 to 1986. She also was a visiting Associate Professor at Dartmouth College in 1990, and at UC San Diego in 1998, while on sabbatical from CU-Boulder . While at CU-Boulder, Nemeth was well known for her undergraduate systems administration activity, in which students over the years had the opportunity to develop in-depth knowledge and skills in Unix system administration. Together with Steve Wozniak, Nemeth established the Woz scholarship program at CU-Boulder which funded inquisitive undergraduates for many years. Nemeth also had a special talent for inspiring and teaching young people. She mentored numerous middle- and high-school students, who worked with her to support computing in the college and came to be known as "the munchkins". She also mentored talented young undergraduates, taking them  to national meetings where they installed networks and broadcast the meetings' sessions on the Internet on the multicast backbone. She coached the university's student programming teams in the ACM International Collegiate Programming Contest. From 1998 to 2006, Nemeth worked with Cooperative Association for Internet Data Analysis (CAIDA) at the University of California, San Diego, on various Internet measurement and visualization projects. Outside the United States, Nemeth helped bring Internet technology to the developing world through her involvement with programs of the Internet Society and the United Nations Development Programme. A network guru T-shirt from the 1980s shows OSI  Model layers with additional Layer 8 as the "financial" layer, and Layer 9 as the "political" layer. The design was credited to Evi Nemeth. Later life. After her retirement, Nemeth sailed her 40-foot sailboat "Wonderland" around various parts of the world, including a circuit of the Atlantic; the Panama Canal; and across the Pacific to New Zealand. She, along with the other crew aboard the vintage yacht "Niña", traveled across the Tasman Sea en route to Australia from New Zealand. The Tasman Sea had 65 mile-per-hour winds and reached 26 feet. A natural disaster might have led  to the disappearance of the boat. They were last heard on June 4, 2013. On July 5, 2013, New Zealand authorities officially ended the search for the "Niña", however relatives of the crew of "Niña" have continued to search. Quotes. "Early ethernet developers... objected to a roundoff error that exceeded the ARPANET's entire bandwidth, but marketing won out." "Many people equate the word ‘daemon’ with the word ‘demon’, implying some kind of Satanic connection between Unix and the underworld. This is an egregious misunderstanding. ‘Daemon’ is actually a much older form of ‘demon’; daemons have no particular bias towards  good or evil, but rather serve to help define a person's character or personality. The ancient Greeks' concept of a ‘personal daemon’ was similar to the modern concept of a ‘guardian angel’ – ‘eudaemonia’ is the state of being helped or protected by a kindly spirit. As a rule, Unix systems seem to be infested with both daemons and demons." (p. 403, "USAH")
