Foo (other)
The terms foobar (), foo, bar, baz, and others are used as metasyntactic variables and placeholder names in computer programming or computer-related documentation. - Etymology of "Foo" They have been used to name entities such as Variable (computer science), variables, Function (computer science), functions, and command (computing), commands whose exact identity is unimportant and serve only to demonstrate a concept. History and etymology It is possible that ''foobar'' is a playful allusion to the World War II-era military slang List of military slang terms#FUBAR, FUBAR (''Fucked Up Beyond All Recognition)''. According to an Internet Engineering Task Force Request for Comments, RFC, the word FOO originated as a nonsense word with its earliest documented use in the 1930s comic ''Smokey Stover'' by Bill Holman (cartoonist), Bill Holman. Holman states that he used the word due to having seen it on the bottom of a jade Chinese figurine in Chinatown, San Francisco, San Francisco ...

Metasyntactic Variable
A metasyntactic variable is a specific word or set of words identified as a placeholder in computer science and specifically computer programming. These words are commonly found in source code and are intended to be modified or substituted before real-world usage. The words foo and bar are good examples as they are used in over 330 Internet Engineering Task Force Requests for Comments, the documents which define foundational internet technologies like HTTP (web), TCP/IP, and email protocols. By mathematical analogy, a metasyntactic variable is a word that is a variable for other words, just as in algebra letters are used as variables for numbers. Metasyntactic variables are used to name entities such as variables, functions, and commands whose exact identity is unimportant and serve only to demonstrate a concept, which is useful for teaching programming. Common metasyntactic variables Due to English being the foundation-language, or lingua franca, of most computer programming la ...

Fu (character)
The character ''Fú'' (, Unicode U+798F) meaning "fortune" or "good luck" is represented both as a Chinese ideograph and, at times, pictorially, in one of its homophonous forms. It is often found on a figurine of the male god of the same name, one of the trio of "star gods" ''Fú, Lù, Shòu''. Mounted ''Fú'' are a widespread Chinese tradition associated with Chinese New Year and can be seen on the entrances of many Chinese homes worldwide. The characters are generally printed on a square piece of paper or stitched in fabric. The practice is universal among Chinese people regardless of socioeconomic status, and dates to at least the Song Dynasty (AD 960 – 1279). When displayed as a Chinese ideograph, ''Fú'' is often displayed upside-down on diagonal red squares. The reasoning is based on a wordplay: in nearly all varieties of Chinese, the words for "upside-down" (, Pinyin: dào) and "to arrive" (, Pinyin: dào) are homophonous. Therefore, the phrase an "upside-down ''Fú ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colossal Cave Adventure
''Colossal Cave Adventure'' (also known as ''Adventure'' or ''ADVENT'') is a text-based adventure game, released in 1976 by developer Will Crowther for the PDP-10 mainframe computer. It was expanded upon in 1977 by Don Woods. In the game, the player explores a cave system rumored to be filled with treasure and gold. The game is composed of dozens of locations, and the player moves between these locations and interacts with objects in them by typing one- or two-word commands which are interpreted by the game's natural language input system. The program acts as a narrator, describing the player's location and the results of the player's attempted actions. It is the first well-known example of interactive fiction, as well as the first well-known adventure game, for which it was also the namesake. The original game, written in 1975 and 1976, was based on Crowther's maps and experiences caving in Mammoth Cave in Kentucky, the longest cave system in the world; further, it was intended ...

Om Mani Padme Hum
' ( sa, ॐ मणि पद्मे हूँ, ) is the six-syllabled Sanskrit mantra particularly associated with the four-armed Shadakshari form of Avalokiteshvara, the bodhisattva of compassion. It first appeared in the Mahayana ''Kāraṇḍavyūhasūtra'' where it is also referred to as the ''sadaksara'' (six syllabled) and the ''paramahrdaya'', or “innermost heart” of Avalokiteshvara. In this text the mantra is seen as the condensed form of all Buddhist teachings. The precise meaning and significance of the words remains much discussed by Buddhist scholars. The literal meaning in English has been expressed as "praise to the jewel in the lotus", or as a declarative aspiration possibly meaning "I in the jewel-lotus". ''Padma'' is the Sanskrit for the Indian lotus (''Nelumbo nucifera''), and ''mani'' for "jewel", as in a type of spiritual "jewel" widely referred to in Buddhism. The first word, '' aum/om'', is a sacred syllable in various Indian religions, and ''hum'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scram
A scram or SCRAM is an emergency shutdown of a nuclear reactor effected by immediately terminating the fission reaction. It is also the name that is given to the manually operated kill switch that initiates the shutdown. In commercial reactor operations, this type of shutdown is often referred to as a "scram" at boiling water reactors (BWR), a "reactor ''trip''" at pressurized water reactors and at a CANDU reactor. In many cases, a scram is part of the routine shutdown procedure, which serves to test the emergency shutdown system. The etymology of the term is a matter of debate. United States Nuclear Regulatory Commission historian Tom Wellock notes that ''scram'' is English-language slang for leaving quickly and urgently, and cites this as the original and most likely accurate basis for the use of ''scram'' in the technical context. A persistent alternative explanation posits that ''scram'' is an acronym for "safety control rod axe man", which was supposedly coined by Enrico ...

Tech Model Railroad Club
The Tech Model Railroad Club (TMRC) is a student organization at the Massachusetts Institute of Technology (MIT). Historically it has been a wellspring of hacker culture and the oldest such hacking group in North America. Formed in 1946, its HO scale layout specializes in automated operation of model trains. History The first meeting of the Tech Model Railroad Club was organized by John Fitzallen Moore and Walter Marvin in November of 1946. Moore and Marvin had membership cards #0 and #1 and served as the first president and vice-president respectively. They then switched roles the following year. Circa 1948, the club obtained official MIT campus space in Room 20E-214, on the third floor of Building 20, a "temporary" World War II-era structure, sometimes called "the Plywood Palace", which had been home to the MIT Radiation Lab during World War II. The club's members, who shared a passion to find out how things worked and then to master them, were among the first Hacker (term), ha ...
