writing the application to directly access device registers and machine addresses. "To get 19.2 kilobaud on the serial port, you need to get down to the bare metal." People who can do this sort of thing well are held in high regard.
barf /barf/ n.,v. [from mainstream slang meaning 'vomit'] 1. interj. Term of disgust. This is the closest hackish equivalent of the Valspeak "gag me with a spoon". (Like, euwww!) See bletch. 2. vi. To say "Barf!" or emit some similar expression of disgust. "I showed him my latest hack and he barfed" means only that he complained about it, not that he literally vomited. 3. vi. To fail to work because of unacceptable input, perhaps with a suitable error message, perhaps not. Examples: "The division operation barfs if you try to divided by 0.'' (That is, the division operation checks for an attempt to divide by zero, and if one is encountered it causes the operation to fail in some unspecified, but generally obvious, manner.) "The text editor barfs if you try to read in a new file before writing out the old one." See choke, gag. In Commonwealth Hackish, barf is generally replaced by 'puke' or 'vom'. barf is sometimes also used as a metasyntactic variable, like foo or bar.
barfmail n. Multiple bounce messages accumulating to the level of serious annoyance, or worse. The sort of thing that happens when an internetwork mail gateway goes down or wonky.
barfulation /bar'fyoo-lay'shU0259.gifn/ interj. Variation of barf used around the Stanford area. An exclamation, expressing disgust. On seeing some particularly bad code one might exclaim, "Barfulation! Who wrote this, Quux?"
barfulous /bar'fyoo-lU0259.gifs/ adj. (alt. barfucious, /bar-fyoo-shU0259.gifs/) Said of something that would make anyone barf, if only for esthetic reasons.
barney n. In Commonwealth hackish, barney is to fred (sense #1) as bar is to foo. That is, people who commonly use fred as their first metasyntactic variable will often use barney second. The reference is, of course, to Fred Flintstone and Barney Rubble in the Flintstones cartoons.
baroque adj. Feature-encrusted; complex; gaudy; verging on excessive. Said of hardware or (esp.) software designs, this has many of the connotations of elephantine or monstrosity but is less extreme and not pejorative in itself. "Metafont even has features to introduce random variations to its letterform output. Now that is baroque!" See also rococo.
