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] |

Programming Game
A programming game is a video game that incorporates elements of computer programming, enabling the player to direct otherwise autonomous units within the game to follow commands in a domain-specific programming language, often represented as a visual language to simplify the programming metaphor. Programming games broadly fall into two areas: single-player games where the programming elements either make up part of or the whole of a puzzle video game, and multiplayer games where the player's automated program is pitted against other players' programs. As puzzle games Early games in the genre include '' System 15000'' and ''Hacker'', released in 1984 and 1985 respectively. Programming games have been used as part of puzzle games, challenging the player to achieve a specific result once the program starts operating. An example of such a game is ''SpaceChem'', where the player must use its visual language to manipulate two waldos as to disassemble and reassemble chemical molecu ...

Robert Morris Sr
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' () "fame, glory, honour, praise, renown, godlike" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin.Reaney & Wilson, 1997. ''Dictionary of English Surnames''. Oxford University Press. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe, the name entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including Engl ...

Machine Code
In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers, machine code is the binaryOn nonbinary machines it is, e.g., a decimal representation. representation of a computer program that is actually read and interpreted by the computer. A program in machine code consists of a sequence of machine instructions (possibly interspersed with data). Each machine code instruction causes the CPU to perform a specific task. Examples of such tasks include: # Load a word from memory to a CPU register # Execute an arithmetic logic unit (ALU) operation on one or more registers or memory locations # Jump or skip to an instruction that is not the next one In general, each architecture family (e.g., x86, ARM) has its own instruction set architecture (ISA), and hence its own specific machine code language. There are exceptions, such as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relocation (computer Science)
In software development, relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. A linker usually performs relocation in conjunction with ''symbol resolution'', the process of searching files and libraries to replace symbolic references or names of libraries with actual usable addresses in memory before running a program. Relocation is typically done by the linker at link time, but it can also be done at load time by a relocating loader, or at run time by the running program itself. Segmentation Object files are typically segmented into various memory segment or section types. Example segment types include code segment (.text), initialized data segment (.data), uninitialized data segment (.bss), or others as established by the programmer, such as common segments, or named static segments. Relocation table The relocation table is a list of address ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Code
In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...

Tron
''Tron'' (stylized as ''TRON'') is a 1982 American science fiction action adventure film written and directed by Steven Lisberger from a story by Lisberger and Bonnie MacBird. The film stars Jeff Bridges as Kevin Flynn, a computer programmer and video game developer who is transported inside the software world of a mainframe computer where he interacts with programs in his attempt to escape. It also stars Bruce Boxleitner, David Warner, Cindy Morgan, and Barnard Hughes. ''Tron'' was one of cinema's earliest films to use extensive computer-generated imagery (CGI). The inspiration for ''Tron'' dates back to 1976, when Lisberger became intrigued with video games after seeing ''Pong''. He and producer Donald Kushner set up an animation studio to develop ''Tron'' with the intention of making it an animated film. To promote the studio itself, Lisberger and his team created a 30-second animation featuring the first appearance of the title character. Eventually, Lisberger decide ...

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] |
