Karim,
First, I want to apologize for keeping this discussion going on.
I think the purpose of this list is not for people to do their laundry.
However, if I insist on this and even brought it up again yesterday, is
because I had hoped that we could have one single RT Linux by this
time (it's been a while since this kind of "unification" was first
suggested).
Second, I never meant to say that the RTAI people, Paolo included,
haven't contributed in spreading, improving, debugging, or even making
smoother this "wheel". What I can't accept is his denial that he and
the RTAI group based their system on Michael and Victor's RTLinux. Not
to mention that they took advantage of RTLinux popularity to trail their
system, which would initially "remain an in house effort based on our
in house needs, and on our amusement in developing it" (in Paolo's own
words), on the RTLinux's wagon. And now, they "spit on their own food".
Have you ever seen the first version of Linux, by Linus? It could
be printed out on a few sheets of paper. Have you seen how many lines of
code the current kernel has? Nevertheless, the system is still called
Linux, and there is no one that can go without recognizing the talent,
intelligence, courage, open mind, and pioneer spirit of Linus.
Unfortunately, I think that *you* got it upside down. Because you
see it as "Paolo and all the other RTAI developers ... have been very
keen to recognize the contributions of RTL", but what Paolo really says
is "Clearly RTAI has reinvented the wheel as it was already in use with
DOS, using APIs found elswhere, but not in RTL".
I wish I had saved old emails from when Paolo's memory was actually
keen and he admitted the contributions from RTLinux. It seems that a few
things in life do have the power to erase our memories.
Again, I apologize for this non-technical outburst. Maybe I was
too naive to believe that the unification was possible and RT people
could do the same that was done to Linux itself. After all, humans
cannot overcome human nature. ;-)
Hats on for all of us. ;-)
