I see no X here.

   Hackers (and the interactive computer games they write) traditionally
   favor this slightly marked usage over other possible equivalents such
   as  "There's no X here!" or "X is missing." or "Where's the X?". This
   goes  back  to  the  original PDP-10 {ADVENT}, which would respond in
   this  wise  if  you  asked it to do something involving an object not
   present at your location in the game.
