   This summer I found a fairly interesting bug in UNIX.  It is simple, easy
to understand and very cute to tell a novice.  What the system does is tell you
you have been using 35000% of the cpu if you do the right things at the right
time.

 To wit:

The command login resets the connect time for the terminal session.  It does
nothing to the cpu time used.  The net effect is that the time command tries
to divide a big number by close to zero and give outrageous numbers. (I have
a listing at home that tells that I used 4.5 MILLION percent of the cpu!!!!!)

This is certainly interesting and if this effect can be used effectively for
our military on a network of CRAY-2's, we'll be able to simulate the Soviet
Union and detect when Andropov even thinks. (I was going to say more but this
sounds better)

Postscript:
1.  notice the date in the header.  The actual message was initially written
    a few days before that.
2.  I can't get anything out from pucci so try and get to me at
    pur-ee!9743 (The system admin's have decided to stop being cs or ee' and
    are more interested in being managers so it will be a while before I have
    a real id.
)(oops. no missing parens here)
3.  I would be interested in running a survey of working conditions and job
    satisfaction for systems admin's and programmers (see 2)  As seems to be
    the standard practice I will summarize any ideas when the mail slows down.
