Much to my joy, the software was completed before the hardware. Having been in this industry, I should note that the greatest virtue of the use of Ada is it results in the resignations of the C++ hackers. I am starting a new instrument in Ada. The C++ code that I have received from the vendors should NEVER be used in a medical device. The commercial software for controller board for my servomotor has the interesting feature that the board can apply the full 10 volts to the servo-amplifier at startup. This results in the rotor reaching top speed, ca. 3,000 rpm, with a 9 kilogram rotor with no simple means to slowly decelerate it. This is enough to make one a true believer in Ada!

Strange,but in europe and russia there is no so big blackouts(my friend had 360v in wallplugs,but it was locally caused by mistake with cables ;-). About Nuclear Plant: Whats,nuclear plant aren't connected with special buffer device and there is really some tanger for plant???????? I'm more worry about another things: If medical software are as buggy as USA power network(if not more buggest)i.e. one patient die on one system per 10 years,one per 3 day if we have 1000 patients,it's really bad. Medical soft are sometimes coded in C++(there was "first man killed by hackes " story in 1999 (or 2000?). How many patients killed by programmer...or more precisely,by manager that choose C++ for it)
