Cargo cult programming

Cargo cult programming

Cargo cult programming is a style of computer programming that is characterized by the ritual inclusion of code or program structures that serve no real purpose. Cargo cult programming is typically symptomatic of a programmer not understanding either the bug they were attempting to solve or the apparent solution (compare shotgun debugging, voodoo programming). [citation|title=The New Hacker's Dictionary |author=Eric S. Raymond|year= 1996|publisher=MIT Press|id=ISBN 0262680920]

Cargo cult programming can also refer to the results of (over-)applying a design principle blindly without understanding the reasons behind that design principle in the first place. An example would be a novice being taught that commenting code is good, and then adding comments for lines that are self-explanatory or need no comment; other examples involve overly complex use of design patterns or certain forms of coding style.

The term 'cargo cult', as an idiom, originally referred to aboriginal religions which grew up in the South Pacific after World War II. The practices of these groups centered on building elaborate mock-ups of airplanes and military landing strips in the hope of summoning the god-like airplanes that had brought marvelous cargo during the war [cite web | url = | title = Cargo Cult Programming article | publisher = Softpanorama (slightly skeptical) Open Source Software Education Society | author = Dr. Nikolai Bezroukov | accessdate = 2008-03-25] . Use of the term in computer programming probably derives from Richard Feynman's characterization of certain practices as "cargo cult science".

Cargo cult software engineering

A related term in software engineering is "cargo cult software engineering", coined by Steve McConnell.

McConnell describes software development organizations that attempt to emulate more successful development houses, either by slavishly following a software development process, or by taking a commitment oriented development approach.

In both cases, McConnell contends that competence ultimately determines whether a project succeeds or fails, regardless of the development approach taken; furthermore, he claims that incompetent "impostor organizations", that merely imitate the form of successful software development organizations are, in fact, engaging, in what he calls "Cargo cult software engineering". cite web | url = | title = Cargo Cult Software Engineering | publisher = IEEE Software | author = From the Editor | date = March/April 2000 | accessdate = 2008-05-24 ]
