Dave Fetterman has put together an excellent set of recommendations for string comparision practices.  Now I am really pleased by this because:

  • these recommendations are going to help you to avoid some nasty security weaknesses that might otherwise plague you
  • you get to use ordinal based comparisons more often and they are by far the fastest and cheapest

Speed and Security?  Say it isn't so!
