In military sciences as in highly sensitive State sciences the exact details are
never published. Please do elaborate how secrecies entered into CC! What is the
tradition? Or did it start with DEEP BLUE? And then, how do you feel when you
one time have to defend the factual reality of the invisible (matches of DB2
against commercial progs) and then here you remind us of the existence of the
claimed real in opposition to the invisible. Do you see any need to reform
"classical" CC?
