Rudd Canaday
Rudd Canaday is an American computer systems engineer and a previous member of the technical staff at the Bell Telephone Laboratories in Murray Hill, New Jersey, credited to co-develop the initial design of the Unix file system. In 2015 he joined a Palo Alto based tech startup, Entefy, as a Senior Architect & Engineer. Research and career Canaday received his Bachelor of Arts (BA) in Physics from Harvard University in 1959 and received his Doctor of Philosophy (PhD) in Computer Science from Massachusetts Institute of Technology in 1964. In 1960s, Ken Thompson developed a game called '' Space Travel'' on Multics file system, which ran very slowly on the machine. This caused Thompson to design his own hierarchical file system along with Dennis Ritchie, Doug McIlroy and Canaday. Joe Ossanna also joined Thompson, Ritchie and Canaday to program the operating system called Unics, later named Unix. In 1973, Canaday along with Evan Ivie started developing the Programmer's Workbench ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Space Travel (video Game)
''Space Travel'' is an early video game developed by Ken Thompson in 1969 that simulation video game, simulates travel in the Solar System. The player flies their ship around a two-dimensional scale model of the Solar System with no objectives other than to attempt to land on various planets and moons. The player can move and turn the ship, and adjust the overall speed by adjusting the scale of the simulation. The ship is affected by the single strongest gravity, gravitational pull of the astronomical bodies. The game was Software development, developed at Bell Labs before the rise of the commercial video game industry in the early history of video games, and was ported during 1969 from the Multics operating system to the General Comprehensive Operating System, GECOS operating system on the GE-600 series, GE 635 computer, and then to the PDP-7 computer. As a part of porting the game to the PDP-7, Thompson developed his own operating system, which later formed the core of the Uni ...

History Of Unix
The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-600 series, GE-645 mainframe. Multics introduced many Multics#Novel ideas, innovations, but also had many problems. Bell Labs, frustrated by the size and complexity of Multics but not its aims, slowly pulled out of the project. Their last researchers to leave Multics – among them Ken Thompson, Dennis Ritchie, Douglas McIlroy, Doug McIlroy, and Joe Ossanna – decided to redo the work, but on a much smaller scale. APDF/ref> In 1979, Ritchie described the group's vision for Unix: 1960s Multics In the late 1960s, Bell Labs was involved in a project with Massachusetts Institute of Technology, MIT and General Electric to develop a time-sharing system, called Multics, allowing multiple users to access a mainframe computer, mainframe simultaneously.

PWB/UNIX
The Programmer's Workbench (PWB/UNIX) was an early, now discontinued, version of the Unix operating system that had been created in the Bell Labs Computer Science Research Group of AT&T. Its stated goal was to provide a time-sharing working environment for large groups of programmers, writing software for larger batch processing computers. Prior to 1973 Unix development at AT&T was a project of a small group of researchers in Department 1127 of Bell Labs. As the usefulness of Unix in other departments of Bell Labs was evident, the company decided to develop a version of Unix tailored to support programmers in production work, not just research. The Programmer's Workbench was started in 1973,John R. Mashey (2004)Languages, Levels, Libraries, and Longevity. ACM Queue 2 (9). by Evan Ivie and Rudd Canaday to support a computer center for a 1000-employee Bell Labs division, which would be the largest Unix site for several years.

Douglas McIlroy
Malcolm Douglas McIlroy (born 1932) is an American mathematician, engineer, and programmer. As of 2019 he is an Adjunct Professor of Computer Science at Dartmouth College. McIlroy is best known for having originally proposed Unix pipelines and developed several Unix tools, such as echo, spell, diff, sort, join, graph, speak, and tr. He was also one of the pioneering researchers of macro processors and programming language extensibility. He participated in the design of multiple influential programming languages, particularly PL/I, SNOBOL, ALTRAN, TMG and C++. His seminal work on software componentization and code reuse makes him a pioneer of component-based software engineering and software product line engineering. Biography McIlroy earned his bachelor's degree in engineering physics from Cornell University, and a Ph.D. in applied mathematics from MIT in 1959 for his thesis ''On the Solution of the Differential Equations of Conical Shells'' (advisor Eric Reissner). ...

Dennis MacAlistair Ritchie (September 9, 1941 – October 12, 2011) was an American computer scientist. He created the C programming language and the Unix operating system and B language with long-time colleague Ken Thompson. Ritchie and Thompson were awarded the Turing Award from the Association for Computing Machinery (ACM) in 1983, the IEEE Richard W. Hamming Medal from the Institute of Electrical and Electronics Engineers (IEEE) in 1990, and the National Medal of Technology from President Bill Clinton in 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007. Early life and education Dennis Ritchie was born in Bronxville, New York. His father was Alistair E. Ritchie, a longtime Bell Labs scientist and co-author of ''The Design of Switching Circuits'' on switching circuit theory. As a child, Dennis moved with his family to Summit, New Jersey, where he graduated from Summit High School. He graduated from Harvard Un ...
