Bad programmer John made a code error, which forced each user to spend an average of 15 minutes searching for a solution. There were 10 million users. 150 million minutes are wasted = 2.5 million hours. If a person sleeps 8 hours a day, then he has 16 hours left for conscious activity. That is, John destroyed 156250 man-days ≈ 427.8 man-years. The average man lives 64 years, meaning John killed approximately six hundred and sixty-eight people.



How do you sleep, John, a serial programmer?
