Drinking tea at my townhouse with a friend, last week. We start talking about a Google engineer Rockwell (* name changed).
"Group X started jovially calling Rockwell 'Mr. No', because he says no to so many of their requests."
"It's not just that group. Everyone calls him that."
"Someone even wrote a device driver in the linux kernel called /proc/rockwell. If you run it on production machines, it prints out 'No.'"
"[laughing] That's awesome!"
"Actually, nine out of ten times, it outputs 'No.' The tenth time, it writes 'We're already doing that.'"
