Knights Of The Lambda Calculus
The Knights of the Lambda Calculus is a semi-fictional organization of expert Lisp (programming language), Lisp and Scheme (programming language), Scheme Hacker (programmer subculture), hackers. The name refers to the lambda calculus, a mathematical formalism invented by Alonzo Church, with which Lisp is intimately connected, and references the Knights Templar. There is no actual organization that goes by the name ''Knights of the Lambda Calculus''; it mostly only exists as a hacker culture in-joke. The concept most likely originated at Massachusetts Institute of Technology, MIT. For example, in the Structure and Interpretation of Computer Programs]video lectures Gerald Jay Sussman presents the audience with the button, saying they are now members of this special group. However, according to the Jargon File, a "well-known LISPer" has been known to give out buttons with Knights insignia on them, and some people have claimed to have membership in the Knights.

Lambda Calculus
Lambda calculus (also written as ''λ''-calculus) is a formal system in mathematical logic for expressing computation based on function abstraction and application using variable binding and substitution. It is a universal model of computation that can be used to simulate any Turing machine. It was introduced by the mathematician Alonzo Church in the 1930s as part of his research into the foundations of mathematics. Lambda calculus consists of constructing § lambda terms and performing § reduction operations on them. In the simplest form of lambda calculus, terms are built using only the following rules: * x – variable, a character or string representing a parameter or mathematical/logical value. * (\lambda x.M) – abstraction, function definition (M is a lambda term). The variable x becomes bound in the expression. * (M\ N) – application, applying a function M to an argument N. M and N are lambda terms. The reduction operations include: * (\lambda x.M \rightarrow(\l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freemasonry
Freemasonry or Masonry refers to fraternal organisations that trace their origins to the local guilds of stonemasons that, from the end of the 13th century, regulated the qualifications of stonemasons and their interaction with authorities and clients. Modern Freemasonry broadly consists of two main recognition groups: * Regular Freemasonry insists that a volume of scripture be open in a working lodge, that every member profess belief in a Supreme Being, that no women be admitted, and that the discussion of religion and politics be banned. * Continental Freemasonry consists of the jurisdictions that have removed some, or all, of these restrictions. The basic, local organisational unit of Freemasonry is the Lodge. These private Lodges are usually supervised at the regional level (usually coterminous with a state, province, or national border) by a Grand Lodge or Grand Orient. There is no international, worldwide Grand Lodge that supervises all of Freemasonry; each Grand Lod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anime
is Traditional animation, hand-drawn and computer animation, computer-generated animation originating from Japan. Outside of Japan and in English, ''anime'' refers specifically to animation produced in Japan. However, in Japan and in Japanese, (a term derived from a shortening of the English word ''animation'') describes all animated works, regardless of style or origin. Animation produced outside of Japan with similar style to Japanese animation is commonly referred to as anime-influenced animation. The earliest commercial Japanese animations date to 1917. A characteristic art style emerged in the 1960s with the works of cartoonist Osamu Tezuka and spread in following decades, developing a large domestic audience. Anime is distributed theatrically, through television broadcasts, Original video animation, directly to home media, and Original net animation, over the Internet. In addition to original works, anime are often adaptations of Japanese comics (manga), light novels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jargon File
The Jargon File is a glossary and usage dictionary of slang used by computer programmers. The original Jargon File was a collection of terms from technical cultures such as the MIT AI Lab, the Stanford AI Lab (SAIL) and others of the old ARPANET AI/ LISP/PDP-10 communities, including Bolt, Beranek and Newman, Carnegie Mellon University, and Worcester Polytechnic Institute. It was published in paperback form in 1983 as ''The Hacker's Dictionary'' (edited by Guy Steele), revised in 1991 as ''The New Hacker's Dictionary'' (ed. Eric S. Raymond; third edition published 1996). The concept of the file began with the Tech Model Railroad Club (TMRC) that came out of early TX-0 and PDP-1 hackers in the 1950s, where the term hacker emerged and the ethic, philosophies and some of the nomenclature emerged. 1975 to 1983 The Jargon File (referred to here as "Jargon-1" or "the File") was made by Raphael Finkel at Stanford in 1975. From that time until the plug was finally pulled on the SAIL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lisp (programming Language)
Lisp (historically LISP) is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in 1960, Lisp is the second-oldest high-level programming language still in common use, after Fortran. Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket and Clojure. Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) the notation of Alonzo Church's lambda calculus. It quickly became a favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order functions, recursion, the self-hosting compiler, and the read ...
