The New Hacker's Dictionary

flavorful // adj.

Full of flavor (sense 2); esthetically pleasing. See random and losing for antonyms. See also the entries for taste and elegant.

flippy /flip'ee/ n.

A single-sided floppy disk altered for double-sided use by addition of a second write-notch, so called because it must be flipped over for the second side to be accessible. No longer common.

flood // v.

[common]

1. To overwhelm a network channel with mechanically-generated traffic; especially used of IP, TCP/IP, UDP, or ICMP denial-of-service attacks.

2. To dump large amounts of text onto an IRC channel. This is especially rude when the text is uninteresting and the other users are trying to carry on a serious conversation. Also used in a similar sense on Usenet.

3. [Usenet] To post an unusually large number or volume of files on a related topic.

flowchart // n.

[techspeak] An archaic form of visual control-flow specification employing arrows and 'speech balloons' of various shapes. Hackers never use flowcharts, consider them extremely silly, and associate them with COBOL programmers, card wallopers, and other lower forms of life. This attitude follows from the observations that flowcharts (at least from a hacker's point of view) are no easier to read than code, are less precise, and tend to fall out of sync with the code (so that they either obfuscate it rather than explaining it, or require extra maintenance effort that doesn't improve the code). See also PDL, sense 1.

flower key // n.

[Mac users] See feature key.

flush // v.

1. [common] To delete something, usually superfluous, or to abort an operation. "All that nonsense has been flushed."
