yes.

what you did was in essence to piss on his code, concepts and
description. [oh, i wrote roughly half of ktimers, so you pissed on my
code too ;-) ]

Here are a few snippets from you that show that most of the negative
messaging from you was directed against the text Thomas wrote (or
against Thomas), not against the code:

" How you get to these conclusions is still rather unclear, I don't even
really know what the problem is from just reading the pretext. "

" What is seriously missing here is the big picture. "

" This no answer at all, you only repeat what you already said above. "

" The main problem with your text is that you jump from one topic to the
next, making it impossible to create a coherent picture from it. "

" You don't think that having that much timers in first place is little
insane (especially if these are kernel timers)? "

" Later it becomes clear that you want high resolution timers, what
doesn't become clear is why it's such an essential feature that
everyone has to pay the price for it (this does not only include
changes in runtime behaviour, but also the proposed API changes). "

" It's nice that you're sure of it, but as long don't provide the means
to verify them, they are just assertions. "

note that these were pretty much out of the blue sky, and they pretty
much set the stage. Given that Thomas is a volunteer too, he does not
have to bear with what he senses as arbitrary abuse.

maybe because your 'get him back to a normal conversation' attempt used
precisely the same somewhat dismissive and somewhat derogatory tone and
type of language that your initial mails were using? Past experience is
extrapolated to the future, so even small negative messages get easily
blown up, and the "cycle of violence" never stops, because nobody breaks
the loop.

maybe it is insulting because the "get over yourself" implicitly
suggests that the fault is with Thomas?

Let me give you a few alternatives, that might have had a completely
different effect and which do not contain any implicit insults:
"So Thomas, I know we got on to the wrong footing, but lets start
talking again."

or:

"So Thomas, I know we had a couple of nasty exchanges in the past, but
lets bury the hatchet and try again. I apologize if I offended you in
any way in the past."

just try it, really. Even if it's a bold faced lie ;)

Thomas wrote you 11 replies in 2.5 months, and some of those were
extremely detailed. That's a far cry from not talking at all. He did try
hard, he did get involved in a flamewar with you, which wasnt overly
productive. But he is a volunteer, he has no obligation to waste time on
flamewars.

yes, i definitely was not nice in a couple of mails, and i'd like to
apologize for it.

ok, apology taken :)

well, direct communication with you has proven to be very unproductive a
number of times, so what would have been the point? But we did mention
lots of technical points in our subsequent mails, referring to your
ptimers queue a number of times. We even adopted the ktime.h
simplification idea and credited you for it.

also, what did you expect? Basically you came out with a patch-queue
based on ktimers, but you did not send any changes against the ktimers
patch itself, which made it very hard to map the real finegrained
changes you did to ktimers. You provided a writeup of differences, but
they did not fully cover the full scope of changes, relative to ktimers.
You based your queue on a weeks old version of ktimers, which also
raises the possibility that you were working on this for some time, in
private, for whatever reason. (Again, this is not a complaint - we are
happy you are communicating via code - whatever form that code is in.)

they were not ignored - we mentioned the ptimer changes in our
subsequent announcements, and we Cc:-ed you to those annoucements so
that you get it first-hand.
