Description: I needed a bunch of truth-tables, with random result-rows, as exercises for logical minimization. An easy task utilizing Perl:
perl -e "print sprintf('%03b',$_).' '.int(rand()+0.5).$/ for 0..7"

    Really no need for both print and sprintf when just printf will suffice. And while I'm at it, I'll just reach into my (perl) golf bag and club your code down some:
    perl -e'printf"%03b %b\n",$_,rand(2)for 0..7'
      I really like this - it's shorter and easier to read!

      You can chop one character off like perl -e'printf"%03b %b\n",$_,rand 2for 0..7'.
