This talk tells the history of the BSD Daemon. It starts with the first renditions in the 1970s of the daemons that help UNIX systems provide services to users. These early daemons were the inspiration for the well-known daemon created by John Lasseter in the early 1980s that became synonymous with BSD as they adorned the covers of the first three editions of `The Design and Implementation of the BSD Operating System' textbooks. The talk will also highlight many of the shirt designs that featured the BSD Daemon.
Dr. Marshall Kirk McKusick writes books and articles, teaches classes on UNIX- and BSD-related subjects, and provides expert-witness testimony on software patent, trade secret, and copyright issues particularly those related to operating systems and filesystems. He has been a developer and committer to the FreeBSD Project since shortly after its founding in 1993. While at the University of California at Berkeley, he implemented the 4.2BSD fast filesystem and was the Research Computer Scientist at the Berkeley Computer Systems Research Group (CSRG) overseeing the development and release of 4.3BSD and 4.4BSD. He earned his undergraduate degree in electrical engineering from Cornell University and did his graduate work at the University of California at Berkeley, where he received master's degrees in computer science and business administration and a doctoral degree in computer science. He has twice been president of the board of the Usenix Association, served nine years as a board member and treasurer of the FreeBSD Foundation, is a senior member of the IEEE, and a member of ACM, and AAAS.
In his spare time, he enjoys swimming, scuba diving, and wine collecting. The wine is stored in a specially constructed wine cellar (accessible from the Web at http://www.mckusick.com/~mckusick/) in the basement of the house that he shares with Eric Allman, his partner of 45-and-some-odd years and husband since 2013.
