break
1. vt. To cause to be broken (in any sense). "Your latest patch to the editor broke the paragraph commands." 2. v. (of a program) To stop temporarily, so that it may debugged. The place where it stops is a `breakpoint'. 3. [techspeak] vi. To send an RS-232 break (two character widths of line high) over a serial comm line. 4. [UNIX] vi. To strike whatever key currently causes the tty driver to send SIGINT to the current process. Normally, break (sense 3) or delete does this. 5. `break break' may be said to interrupt a conversation (this is an example of verb doubling). This usage comes from radio communications, which in turn probably came from landline telegraph/teleprinter usage, as badly abused in the Citizen's Band craze a few years ago.
break-even point
n. in the process of implementing a new computer language, the point at which the language is sufficiently effective that one can implement the language in itself. That is, for a new language called, hypothetically, FOOGOL, one has reached break-even when one can write a demonstration compiler for FOOGOL in FOOGOL, discard the original implementation language, and thereafter use older versions of FOOGOL to develop newer ones. This is an important milestone; see {MFTL}.
breath-of-life packet
[XEROX PARC] n. An Ethernet packet that contained bootstrap (see {boot}) code, periodically sent out from a working computer to infuse the `breath of life' into any computer on the network that had happened to crash. Machines depending on such packets have sufficient hardware or firmware code to wait for (or request) such a packet during the reboot process. See also {dickless workstation}.
breedle
n. See {feep}.
