He has been actively working with Unix since 1976 when he first encountered it at Case Western Reserve University, and he has been involved with what people now think of as open source, as he says, \u201clong before it was even termed open source.\u201d While working for the Computer Systems Research Group (CSRG) at the University of California at Berkeley, he helped with the 4.1BSD release and was responsible for the release of 4.2BSD. He has contributed to almost every aspect of BSD systems, most recently working (again) on the networking subsystem.<\/jats:p>","DOI":"10.1145\/1005062.1005076","type":"journal-article","created":{"date-parts":[[2005,1,26]],"date-time":"2005-01-26T16:33:14Z","timestamp":1106757194000},"page":"16-22","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["A Conversation with Sam Leffler"],"prefix":"10.1145","volume":"2","author":[{"given":"James","family":"Russell","sequence":"first","affiliation":[{"name":"IBM"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2004,5]]},"container-title":["Queue"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/1005062.1005076","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/dl.acm.org\/doi\/pdf\/10.1145\/1005062.1005076","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T21:38:33Z","timestamp":1750282713000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/1005062.1005076"}},"subtitle":["A Unix and BSD pioneer discusses the open source movement."],"short-title":[],"issued":{"date-parts":[[2004,5]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2004,5]]}},"alternative-id":["10.1145\/1005062.1005076"],"URL":"https:\/\/doi.org\/10.1145\/1005062.1005076","relation":{},"ISSN":["1542-7730","1542-7749"],"issn-type":[{"type":"print","value":"1542-7730"},{"type":"electronic","value":"1542-7749"}],"subject":[],"published":{"date-parts":[[2004,5]]},"assertion":[{"value":"2004-05-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
