Mung (computer term)

Last updated

Mung or munge is computer jargon for a series of potentially destructive or irrevocable changes to a piece of data or a file. [1] It is sometimes used for vague data transformation steps that are not yet clear to the speaker. [2] Common munging operations include removing punctuation or HTML tags, data parsing, filtering, and transformation. [2]

The term was coined in 1958 in the Tech Model Railroad Club at the Massachusetts Institute of Technology. [1] In 1960 the backronym "Mash Until No Good" was created to describe Mung, and by 1976 it was revised to "Mung Until No Good", making it one of the first recursive acronyms. [3] It lived on as a recursive command in the editing language TECO. [4]

Munging may also describe the constructive operation of tying together systems and interfaces that were not specifically designed to interoperate (also called 'duct-taping'). Munging can also describe the processing or filtering of raw data into another form. [2]

As the "no good" part of the acronym implies, munging often involves irrevocable destruction of data. [1]

<span class="mw-page-title-main">PDF</span> Portable Document Format, a digital file format

Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991. PDF was standardized as ISO 32000 in 2008. The last edition as ISO 32000-2:2020 was published in December 2020.

XSLT is a language originally designed for transforming XML documents into other XML documents, or other formats such as HTML for web pages, plain text or XSL Formatting Objects, which may subsequently be converted to other formats, such as PDF, PostScript and PNG. Support for JSON and plain-text transformation was added in later updates to the XSLT 1.0 specification.

A recursive acronym is an acronym that refers to itself, and appears most frequently in computer programming. The term was first used in print in 1979 in Douglas Hofstadter's book Gödel, Escher, Bach: An Eternal Golden Braid, in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym. Other references followed, however the concept was used as early as 1968 in John Brunner's science fiction novel Stand on Zanzibar. In the story, the acronym EPT later morphed into "Eptification for Particular Task".

Address munging is the practice of disguising an e-mail address to prevent it from being automatically collected by unsolicited bulk e-mail providers. Address munging is intended to disguise an e-mail address in a way that prevents computer software from seeing the real address, or even any address at all, but still allows a human reader to reconstruct the original and contact the author: an email address such as, "no-one@example.com", becomes "no-one at example dot com", for instance.

A munged password refers to the practice of creating a password with common replacement strategies. For example, replacing 'S' with '$' or '5' in a password. Alternatively, it can be seen as an application of Leet speak. It can lead to creation of secure passwords which are easy to remember, although they are still susceptible to brute-force guessing.

Richard Cameron developed CiteULike in November 2004 and in 2006 Oversity Ltd. was established to develop and support CiteULike. In February 2019, CiteULike announced that it would be ceasing operations as of March 30, 2019.

Data wrangling, sometimes referred to as data munging, is the process of transforming and mapping data from one "raw" data form into another format with the intent of making it more appropriate and valuable for a variety of downstream purposes such as analytics. The goal of data wrangling is to assure quality and useful data. Data analysts typically spend the majority of their time in the process of data wrangling compared to the actual analysis of the data.
