Encyclopedia > Marshall Kirk McKusick

Marshall Kirk McKusick (b. January 19, 1954) is a computer scientist, famous for his extensive work on BSD, from the 1980s to FreeBSD in the present day. He was president of the USENIX Association from 1990 to 1992 and again from 2002 to 2004, and still serves on the board. He is also on the editorial board of ACM Queue Magazine. He is known to friends and colleagues as "Kirk". January 19 is the 19th day of the year in the Gregorian calendar. ... 1954 (MCMLIV) was a common year starting on Friday of the Gregorian calendar. ... Computer science is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. ... BSD redirects here; for other uses see BSD (disambiguation). ... FreeBSD is a Unix-like free software operating system descended from AT&T UNIX via the Berkeley Software Distribution (BSD) branch through 386BSD and 4. ... The USENIX Association is the Advanced Computing Technical Association. ...


McKusick received his B.S. in electrical engineering from Cornell University, and his Master's degree in business administration and Ph.D. in computer science from the University of California, Berkeley. The examples and perspective in this article or section may not represent a worldwide view. ... Electrical engineers design power systems. ... Cornell University is a research university located on the East Hill of Ithaca, New York. ... A masters degree is an academic degree usually awarded for completion of a postgraduate or graduate course of one to three years in duration. ... A doctorate is an academic degree of the highest level. ... University of California, Berkeley The University of California, Berkeley (also known as California, Cal, UCB, UC Berkeley, The University of California, or simply Berkeley) is a public, coeducational university situated east of the San Francisco Bay in Berkeley, California, overlooking the Golden Gate. ...


He lives in California with Eric Allman, his domestic partner since graduate school. McKusick is an avid wine collector and the temperature and vital statistics of his house and wine cellar are available on the web from his homepage. Eric Allman (born 1959) is a computer programmer. ...


BSD

Kirk started with BSD by virtue of the fact that he shared an office at Berkeley with Bill Joy, who in essence spearheaded the beginnings of the BSD system. (source: BSDTalk interview with Kirk McKusick). BSD redirects here; for other uses see BSD (disambiguation). ... William Nelson Joy (born 1954), commonly known as Bill Joy, co-founded Sun Microsystems in 1982 along with Vinod Khosla, Scott McNealy and Andy Bechtolsheim, and served as chief scientist at the company until 2003. ...


Some of McKusick's largest contributions to BSD have been to the file system. He helped design the original Berkeley Fast File System (FFS). More recently, he implemented soft updates, a new approach to maintaining disk integrity after a crash or power outage, in FFS, and a revised version of UFS known as "UFS2". In computing, a file system is a method for storing and organizing computer files and the data they contain to make it easy to find and access them. ... In computing, the Berkeley Fast File System (or FFS) is a file system used mostly by BSD-derivative Unix variants. ... In computer file systems, soft updates are an approach to maintaining disk integrity after a crash or power outage. ... UNIX file system (UFS) is a file system used by many Unix and Unix-like operating systems. ...


He was also primarily responsible for creating the complementary features of filesystem snapshots and background fsck (file system check and repair), which both integrate closely with soft updates. After the filesystem snapshot, the filesystem can be brought up immediately after a power outage, and fsck can run as a background process. The system utility fsck (for file system check or file system consistency check) is a tool for checking the consistency of a file system in the Unix system and clones thereof. ...


The Design and Implementation series of books are regarded as very high quality works in computer science. They have been strongly influential in the development of the BSD descendants and have contributed to their cohesive and well-thought-out nature.
