To defeat a selection mechanism by introducing a (sometimes
|
||
temporary) device that forces a specific result. The word is used in
|
||
several industries; telephone engineers refer to spiking a relay by
|
||
inserting a pin to hold the relay in either the closed or open state, and
|
||
railroaders refer to spiking a track switch so that it cannot be moved. In
|
||
programming environments it normally refers to a temporary change, usually
|
||
for testing purposes (as opposed to a permanent change, which would be
|
||
called <a href="../H/hardwired.html"><i class="glossterm">hardwired</i></a>). </p></dd><dd><p> 2. [borderline techspeak] A visible peak in an otherwise rather
|
||
constant graph (e.g. a sudden surge in line voltage, an unexpected short
|
||
“<span class="quote">high</span>” on a logical line in a circuit). Hackers frequently use
|
||
this for a sudden short increase in some quantity such as system load or
|
||
network traffic.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="spiffy.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../S.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="spin.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">spiffy </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> spin</td></tr></table></div></body></html>
