Unix popularized a syntax for regular expressions that found widespread use. The Unix programming interface became the basis for a widely implemented operating system interface standard (POSIX, see above). The C programming language soon spread beyond Unix, and is now ubiquitous in systems and applications programming.
Unix workstations of the 1990s, including those made by DEC, HP, SGI, and Sun The Common Desktop Environment (CDE) was widely used on Unix workstations. The Unix wars continued into the 1990s, but turned out to be less of a threat than originally thought: AT&T and Sun went their own ways after System V.4, while OSF/1's schedule slipped behind. [46]
Dennis MacAlistair Ritchie (September 9, 1941 – c. October 12, 2011) was an American computer scientist. [3] He created the C programming language and the Unix operating system and B language with long-time colleague Ken Thompson. [3]
Some programs that were part of later versions of Research Unix, such as mk and rc, were also incorporated into Plan 9. Thompson tested early versions of the C++ programming language for Bjarne Stroustrup by writing programs in it, but later refused to work in C++ due to frequent incompatibilities between versions. In a 2009 interview, Thompson ...
The C Programming Language, with C creator Dennis Ritchie, the first book on C; The Practice of Programming, with Rob Pike; The Unix Programming Environment, a tutorial book, with Rob Pike "Why Pascal is Not My Favorite Programming Language", a popular criticism of Niklaus Wirth's Pascal. Some parts of the criticism are obsolete due to ISO 7185 ...
At Sun, Joy was an inspiration for the development of NFS, the SPARC microprocessors, [12] the Java programming language, Jini/JavaSpaces, [13] and JXTA. [14] In 1986, Joy was awarded a Grace Murray Hopper Award by the ACM for his work on the Berkeley UNIX Operating System. [15]
He pursued a doctorate in physics for one year, but left the program to focus on his programming at the MIT AI Laboratory. [ 11 ] [ 14 ] While working (starting in 1975) as a research assistant at MIT under Gerry Sussman , [ 14 ] Stallman published a paper (with Sussman) in 1977 on an AI truth maintenance system , called dependency-directed ...
Pike wrote the first window system for Unix in 1981. [3] [non-primary source needed] He is the sole inventor named in the US patent for overlapping windows on a computer display. [4] With Brian Kernighan, he is the co-author of The Practice of Programming and The Unix Programming Environment. [1]
