Victor A. Vyssotsky
Victor Alexander Vyssotsky (February 26, 1931 – December 24, 2012) was a mathematician and computer scientist. He was the technical head of the Multics project at Bell Labs and later executive director of Research in the Information Systems Division of AT&T Bell Labs. Multics, whilst not particularly commercially successful in itself, directly inspired Ken Thompson to develop Unix. Later, Vyssotsky was the founding director of Digital's Cambridge Research Lab. In 1960, Vyssotsky co-created the BLODI Block Diagram Compiler at Bell Labs. In 1961, together with Robert Morris Sr. and Doug McIlroy, he devised the computer game Darwin (later known as Core War) on an IBM 7090 The IBM 7090 is a second-generation Transistor computer, transistorized version of the earlier IBM 709 vacuum tube mainframe computer that was designed for "large-scale scientific and technological applications".

Computer Game
A video game or computer game is an electronic game that involves interaction with a user interface or input device (such as a joystick, controller, keyboard, or motion sensing device) to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with audio complement delivered through speakers or headphones, and sometimes also with other types of sensory feedback (e.g., haptic technology that provides tactile sensations). Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming. Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and computer games (which includes LAN games, online games, and browser games). More recently, the video game industry h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1931 Births
Events January * January 2 – South Dakota native Ernest Lawrence invents the cyclotron, used to accelerate particles to study nuclear physics. * January 4 – German pilot Elly Beinhorn begins her flight to Africa. * January 22 – Sir Isaac Isaacs is sworn in as the first Australian-born Governor-General of Australia. * January 25 – Mohandas Gandhi is again released from imprisonment in India. * January 27 – Pierre Laval forms a government in France. * January 30 – Charlie Chaplin comedy drama film ''City Lights'' receives its public premiere at the Los Angeles Theater with Albert Einstein as guest of honor. Contrary to the current trend in cinema, it is a silent film, but with a score by Chaplin. Critically and commercially successful from the start, it will place consistently in lists of films considered the best of all time.

IBM 7090
The IBM 7090 is a second-generation Transistor computer, transistorized version of the earlier IBM 709 vacuum tube mainframe computer that was designed for "large-scale scientific and technological applications". The 7090 is the fourth member of the IBM 700/7000 series#Scientific Architecture, IBM 700/7000 series scientific computers. The first 7090 installation was in December 1959. In 1960, a typical system sold for $2.9 million (equivalent to $ million in ) or could be rented for $63,500 a month (). The 7090 uses a 36-bit word length, with an address space of 32,768 words (15-bit addresses). It operates with a basic memory cycle of 2.18 μs, using the IBM 7302 Core Storage Magnetic-core memory, core memory technology from the IBM 7030 (Stretch) project. With a processing speed of around 100 FLOPS, Kflop/s, the 7090 is six times faster than the 709, and could be rented for half the price. An upgraded version, the 7094, was up to twice as fast. Both the 7090 and the 7094 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Core War
''Core War'' is a programming game introduced in 1984 by D. G. Jones and A. K. Dewdney. In the game, two or more battle programs, known as ''warriors'', compete for control of a virtual computer. These programs are written in an abstract assembly language called ''Redcode''. Initial standards for Redcode and the virtual machine were established by the International Core Wars Society (ICWS), with later revisions shaped by community consensus. Gameplay At the start of a match, each warrior is loaded into a random memory location. Programs take turns executing one instruction at a time. A program wins by terminating all opponents, typically by causing them to execute invalid instructions, leaving the victorious program in sole possession of the machine. Early versions of Redcode featured only eight instructions. This number increased to 10 in the ICWS-86 standard, 11 in ICWS-88, and 16 in the 1994 draft standard, which is still widely used. With various addressing modes and ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darwin (programming Game)
Darwin was a programming game invented in August 1961 by Victor A. Vyssotsky, Robert Morris Sr., and M. Douglas McIlroy. (Dennis Ritchie is sometimes incorrectly cited as a co-author, but was not involved.) The game was developed at Bell Labs, and played on an IBM 7090 mainframe there. The game was only played for a few weeks before Morris developed an "ultimate" program that eventually brought the game to an end, as no-one managed to produce anything that could defeat it. Description The game consisted of a program called the ''umpire'' and a designated section of the computer's memory known as the ''arena'', into which two or more small programs, written by the players, were loaded. The programs were written in 7090 machine code, and could call a number of functions provided by the umpire in order to probe other locations within the arena, kill opposing programs, and claim vacant memory for copies of themselves. The game ended after a set amount of time, or when copies of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doug 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). ...
