:hello, world: interj. 1. The canonical minimal test message in the
C/UNIX universe. 2. Any of the minimal programs that emit this
message. Traditionally, the first program a C coder is supposed to
write in a new environment is one that just prints "hello, world"
to standard output (and indeed it is the first example program
in {K&R}). Environments that generate an unreasonably large
executable for this trivial test or which require a {hairy}
compiler-linker invocation to generate it are considered to
{lose} (see {X}). 3. Greeting uttered by a hacker making an
entrance or requesting information from anyone present. "Hello,
world! Is the {VAX} back up yet?"
