1. one liner wars
A game popular among hackers who code in the language APL (see
write-only language and
line noise). The objective is to see who can code the most
interesting and/or useful routine in one line of operators chosen from
APL's exceedingly hairy primitive set. A similar
amusement was practiced among TECO hackers and is
now popular among Perl aficionados.Ken Iverson, the inventor of APL, has been credited with a one-liner
that, given a number N, produces a list of
the prime numbers from 1 to N inclusive.
It looks like this: Here's a Perl program that prints
primes:
perl -wle '(1 x $_) !~ /^(11+)1+$/ && print while ++ $_'

In the Perl world this game is sometimes called Perl Golf because the
player with the fewest (key)strokes wins.
