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]
Also in 1983, Dave Smith's company marketed the first polyphonic synthesizer keyboard that could play more than one sound at a time called the 'Six-Trak'. [22] It had a six track sequencer and each track could access a different sound. The same year the SCI Pooppit T8 with optical key sensing became the first piano action emulating MIDI keyboard.
First implemented as a compile-and-go system rather than an interpreter, BASIC emerged as part of a wider movement towards time-sharing systems. General Electric, having worked on the Dartmouth Time-Sharing System and its associated Dartmouth BASIC, wrote their own underlying operating system and launched an online time-sharing system known as Mark I featuring a BASIC compiler (not an ...
Victor H. Yngve (July 5, 1920 – January 15, 2012 [1]) was a professor of linguistics at the University of Chicago and the Massachusetts Institute of Technology (1953-1965). ). He was one of the earliest researchers in computational linguistics and natural language processing, the use of computers to analyze and process langua
The Kurzweil K250 was the first electronic instrument to faithfully reproduce the sounds of an acoustic grand piano. [5] It could play up to 12 notes simultaneously (known as 12-note polyphony ) by using individual sounds as well as layered sounds (playing multiple sounds on the same note simultaneously, also known as being multitimbral ).
Together with J. C. Shaw [43] and Herbert Simon, the three co-wrote the Logic Theorist, the first true AI program, in the first list-processing language, which influenced LISP. 1943 Newman, Max: Instigated the production of the Colossus computers at Bletchley Park.
The very first time a stored-program computer held a piece of software in electronic memory and executed it successfully, was 11 am 21 June 1948, at the University of Manchester, on the Manchester Baby computer. It was written by Tom Kilburn, and calculated the highest factor of the integer 2^18 = 262,144. Starting with a large trial divisor ...
He is credited with one of the first software hash tables, and influencing early research in using transistors for computers at IBM. [3] At IBM he made the first checkers program on IBM's first commercial computer, the IBM 701. The program was a sensational demonstration of the advances in both hardware and skilled programming and caused IBM's ...
