[dtrace-discuss] John Birrell

It is with a heavy heart that I announce that we in the DTrace community
have lost one of our own: the indomitable John Birrell, who ported DTrace
to FreeBSD, suffered a stroke and passed away on Friday, November 20,
2009.
We on Team DTrace knew John to be a remarkably talented and determined
software engineer. As those who have attempted ports can attest, DTrace
passes through rough country, and a port to a foreign system is a
significant undertaking that requires mastery of both DTrace and
(particularly) the target system. And in being the first to attempt a port,
John's challenge was that much greater -- and his success in the endeavor a
tribute to both his ability and (especially) his tenacity. For example,
in performing the port, John decided that DTrace's dependency on the
cyclic subsystem was such that it, too, needed to be ported. He didn't
need to do this (and indeed, other ports have decided that an arbitrary
resolution profile provider is not worth the significant trouble), but
that he undertook this additional technical challenge anyway -- even when
any victory would remain hidden to all but the most expert eye -- says a
lot about John as both an engineer and a man. Later, when the port ran
into some frustrating licensing issues, John once again did not give up.
Rather, he backed up, and found a path forward that would satisfy all
parties -- even though it required significant technical reworking on his
part. I have long believed that the mark of a great engineer is not how
frequently they get knocked down, but rather how quickly they get back up
-- and in this regard, John was indisputably a giant.
John, you will be missed -- not only by the FreeBSD community upon which
you made an indelible mark, but by those of us in the DTrace community who
only had the opportunity to work with you more recently. And while your
legacy might remain anonymous to the future generations that will benefit
from the fruits of your long labor, we will always know that it never
would have happened without you. Thank you, and farewell.

I did not know John, but your tribute to him was the most touching and
reflective that I have read for some time. It is always sad to suffer a
loss (and I have had two within the last week); so I am certain that
your sentiments will be well-received and echoed by the folks that did
in fact know John.
My condolences to his family and friends.
Regards... Sean.

This is awful, awful news. John was a great guy, a great talent, and an inspiration.
My condolences to his family and friends!

That's sad news. John was a great guy. He was very helpful when I was digging into the FreeBSD implementation trying to write some custom sdt-based providers.
John, we'll miss you
Fer
