QOTW: "...then we get a signal through, then various miracles occur, and
the conclusion is, 'You mean it only takes thirteen lines of code to do
that? Our software folks said it's not possible.'
Cameron Laird, on his typical experience with industrial automation projects

"In fact what you'd really like is a 'resumption' object created by raising
the exception, that you can pass control to at any time, sort of like
yielding from a generator. Maybe you're getting deja vu now, since this is
basically what Stackless Python continuations were."
Paul Rubin, on the idea of resumable exceptions

Magazines have definite appetites for, among other things,
articles of the "What's new in Release 2.x and how to make
best use of it" and "X-ing with three different technologies:
concrete examples of good style" sorts.

I feel responsible for escalating the pugnacity of the process-
control thread. That adds to my responsibility to clarify: FAR
more than any narrow technical complaints about the software of
industrial automation I have, I'm ready to take over as dictator
and change the *approach* of the vendors. It's not so much that
I think the applications and libraries are bad, as that they're
senselessly closed and ludicrously misdocumented. In general.
In my opinion.

Finally, AMK is soooooooo right. His statement is so perfect,
even I can't find anything to add to it.

My question is:

"What do I have to say to get into the QOTW?"

Hardly seems fair... if you or I did it there would be
all manner of rude comments about the phallic connotations
of our new moniker... ;-)
