I am not disagreeing with that. But time is peripheral to the argument.
Minus time, skill set A is not skill set B.

Knowing how to ski does not prevent you from knowing how to drive, and

Knowing one set of skills does not necessarily preclude knowlege of the
other. In fact, one often complements the other. But that is ouside the
scope of the argument.

:What you apparently tried to convey was that the skill sets are
:"completely separate", "non-overlapping", or "independent of each
ther". None of which is equivalent to "mutually exclusive".

The following (from a probablility text at Rice) might suffice for the
sake of this question.

http://www.ruf.rice.edu/~lane/hyperstat/A132677.html

"Two events are mutually exclusive if it is not possible for both of them
to occur. For example, if a die is rolled, the event "getting a 1" and
the event "getting a 2" are mutually exclusive since it is not possible
for the die to be both a one and a two on the same roll. The occurrence
of one event "excludes" the possibility of the other event."

Can you agree with this?

Minus time, you should be able to see that the skill sets of system
administration skills and programming are mutually exclusive. The two
activities are so distinct, that you cannot do both at the same time.

You can be a sysadmin with great programming skills. But when you write
code to automate systems administration tasks, you are programming.

You can be a programmer with great system administration skills. But
when you format a drive, write firewall rules, configure software,
monitor services and vendor equipment, etc., you are doing systems
administration.

I think this problem has more to do with communication than with
English.
