GNU grep was written my Mike Haertel, not Haerkal as written in the article. Super smart guy.

  > GNU grep was written my Mike Haertel, not Haerkal as written in the article. It's a typo, which is odd, because the author could just have copied-and-pasted it from a terminal session, which they obviously know enough to do. % grep -V <snip> Written by Mike Haertel and others, see <http://git.sv.gnu.org/cgit/grep.git/tree/AUTHORS>.

  His email about why GNU grep is fast contains one of my favorite quotes about programming. Don't know if he coined it. > The key to making programs fast is to make them do practically nothing. ;-)
