Nope. I'm a systems theorist and I demand/require variable isolation.
Not a question of "silly" or "dumb" but a question of "speaking with
sufficient precision and clarity".
For instance you speak of "having an impression" and then decide I've
made an assumption.
I define my position. Explain my terms. Give my examples.
I also risk being utterly wrong because sometimes being completely wrong
gets others to cut away misconceptions and assumptions.
It annoys some people, but it gets results. You've been going around on
this topic for how long? and just today Hugo "got" that your problem is
becoming CPU bound (long process) instead of a hard lockup. We've
stopped talking about "trees" and started talking about free space
management. We've stopped talking about 17G of free space and gotten
down to the 5 or so, plus you've gotten angry at me, tried to prove me
an idiot, and so produced test cases and data that is absolutely clear
including steps to reproduce.
In real life I work on mission critical systems that can get people
killed when they fail. So I have developed the reflex of tenacity in
getting everyone using the same words, talking about the same concepts,
giving concrete examples, and generally bringing the discussion to a
very precise head.
Example: I had two parties in conflict about a system. One party said
that every time they did "an orderly shutdown" the device would hang in
a way that took days to recover from. The other party would examine the
device and say "could not reproduce". Turns out that the two parties
were doing entirely different (but both correct) sequences for "orderly
shutdown". They'd been having that conflict for more than a year. But
since they both _knew_ what an "orderly shutdown" was, they _never_
analyzed what they were saying. (turns out one procedure left a chip in
a state that it wouldn't restart until a capacitor discharged, and the
other procedure did not.)
So yea, when people make statements that "everybody understands" and
those statements don't agree. I start slicing concepts off one at a time...
It's not about "dumb" or "silly" it's about exact and accurate
descriptions that have been stripped of assumptions and tribal knowledge.
And I don't care if I come off looking like "the bad guy" because I
don't believe in "the bad guy" at all when it comes to making things
more clear and getting out of a communications deadlock. My only goal is
"less broken".
So occasionally annoying... but look... progress!
