|
n. 1. [from CB slang] An electronic pseudonym; a nom de guerre intended to
|
|
|
|
|
conceal the user's true identity. Network and BBS handles function as the
|
|
|
|
|
same sort of simultaneous concealment and display one finds on Citizen's
|
|
|
|
|
Band radio, from which the term was adopted. Use of grandiose handles is
|
|
|
|
|
characteristic of warez d00dz , cracker s, weenie s, spod s, and other lower
|
|
|
|
|
forms of network life; true hackers travel on their own reputations rather
|
|
|
|
|
than invented legendry. Compare nick , screen name. 2. A magic cookie ,
|
|
|
|
|
often in the form of a numeric index into some array somewhere, through
|
|
|
|
|
which you can manipulate an object like a file or window. The form file
|
|
|
|
|
handle is especially common. 3. [Mac] A pointer to a pointer to
|
|
|
|
|
dynamically-allocated memory; the extra level of indirection allows
|
|
|
|
|
on-the-fly memory compaction (to cut down on fragmentation) or aging out of
|
|
|
|
|
unused resources, with minimal impact on the (possibly multiple) parts of
|
|
|
|
|
the larger program containing references to the allocated memory. Compare
|
|
|
|
|
snap (to snap a handle would defeat its purpose); see also aliasing bug ,
|
|
|
|
|
dangling pointer.
