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?"
