Why GNU grep is fast

I am the original author of GNU grep.  I am also a FreeBSD user,
although I live on -stable (and older) and rarely pay attention

It caught the man’s ankle as it whipped around…

The coolest talk of this year’s Blackhat must have been the one of Sean Devlin and Hanno Böck. The talk summarized this early year’s paper, in a very cool way: Sean walked on stage and announced that he didn’t have his slides. He then said that it didn’t matter because he had a good idea on how to retrieve them…
