lLudwig
sponsored the 1st International Virus Writing Contest in 1993.
lThe
purpose was to design the smallest possible virus having a certain minimal functionality.
lThe
winning entry was 101 bytes in length.
lIf
every elementary particle in the universe were a PC generating a 101-byte file every 10-26 sec from the big bang until now, the chance they would
have produced this one is less than one chance in 10109.
