I understand that this Turkish guy will be added to the list here 
http://en.wikipedia.org/wiki/Turing_Award next year for his stunning 
contribution to the field of computer science.  The year after he will 
win the award again for his outstanding contribution which prevents 
people from sending double spaced crap to this list.
