Rule 1: Never let an oceanographer with 2 FORTRAN courses design or
maintain any software project with more than 16 lines of code checked
into the repository.
Rule 2: Oceanographers with less than 2 formal FORTRAN classes have
decided they're really nacent software engineers because they've
mastered most of the buzzwords, and thus will give you all sorts of
"requirements" which are typically orthogonal to any software design or
engineering training you've had.
Rule 3: If you finally convince the denizens of Rule 2 that their
application cannot be written as spec'd, they are suddenly experts in
"Service Oriented Architecture" and Software as a Service. And you're
not. So there. Just believe me. Really. Cause I said so.
Don't ask me how learned these truths. Oh, and the bar is slightly
higher for meteorologists, by a couple of additional formal software
classes. But in the grand scheme of things, it's not much higher...

ibid. Been there, done that. But not for spacecraft. Or, I could talk
about computer scientists just now discovering what discipline experts
do for the Data-Net NSF call that's out now, but that's another thread...

They're grasping it to keep me from driving it through their hearts...
Oh, yeah. That meeting is already over.

My personal preference is a garlic-flavored wooden stake. I keep the
silver bullets for backup when I missed with the stake.
