feature

fear and loathing = F = feature creature

feature n.

1. [common] A good property or behavior (as of a program). Whether it was intended or not is immaterial. 2. [common] An intended property or behavior (as of a program). Whether it is good or not is immaterial (but if bad, it is also a misfeature). 3. A surprising property or behavior; in particular, one that is purposely inconsistent because it works better that way -- such an inconsistency is therefore a feature and not a bug. This kind of feature is sometimes called a miswart; see that entry for a classic example. 4. A property or behavior that is gratuitous or unnecessary, though perhaps also impressive or cute. For example, one feature of Common LISP's format function is the ability to print numbers in two different Roman-numeral formats (see bells whistles and gongs). 5. A property or behavior that was put in to help someone else but that happens to be in your way. 6. [common] A bug that has been documented. To call something a feature sometimes means the author of the program did not consider the particular case, and that the program responded in a way that was unexpected but not strictly incorrect. A standard joke is that a bug can be turned into a feature simply by documenting it (then theoretically no one can complain about it because it's in the manual), or even by simply declaring it to be good. "That's not a bug, that's a feature!" is a common catchphrase. See also feetch feetch, creeping featurism, wart, green lightning.

The relationship among bugs, features, misfeatures, warts, and miswarts might be clarified by the following hypothetical exchange between two hackers on an airliner:

A: "This seat doesn't recline."

B: "That's not a bug, that's a feature. There is an emergency exit door built around the window behind you, and the route has to be kept clear."

A: "Oh. Then it's a misfeature; they should have increased the spacing between rows here."

B: "Yes. But if they'd increased spacing in only one section it would have been a wart -- they would've had to make nonstandard-length ceiling panels to fit over the displaced seats."

A: "A miswart, actually. If they increased spacing throughout they'd lose several rows and a chunk out of the profit margin. So unequal spacing would actually be the Right Thing."

B: "Indeed."

`Undocumented feature' is a common, allegedly humorous euphemism for a bug. There's a related joke that is sometimes referred to as the "one-question geek test". You say to someone "I saw a Volkswagen Beetle today with a vanity license plate that read FEATURE". If he/she laughs, he/she is a geek.

In archaeology, a feature is any evidence of past human activity that is non-portable. A fire pit, a cache, and the outlines in the dirt showing where old postholes were dug are all features. (Large structures, like mounds, cromlechs, and pyramids can be called either features or artifacts, but usually are not called either).

Sometimes feature is also used to mean the context in which artifacts and ecofacts are found, or the arrangement of the items at a site, as these cannot be moved without altering them. But I believe that it is more common to use features to simply mean specific things, independent from the context in which they are found, and to use the word 'context' when talking about the context.
