to Joyent
was a dream come true. I went
from aspiring
kernel dev

to the mac
. I learned to prevail against bugs that made me
wanna throw my computer out the window, such
as i40e ring
and inside baseball semantics
between vfork
and signal delivery
. I
reviewed a
lot of code
, including this absolutely beautiful patch by
Patrick Mooney to
implement a
faster clock_gettime
. I
read a
lot of code
too, which wasn’t always easy, but sometimes I
was lucky enough to find myself treated to one of
Robert’s epic
block comments
. I fixed some bugs, including a
few brutal
that would lockup compute nodes weekly and crash
customer manta jobs.
I created
of my own.
I panicked
a lot of kernels (*slaps /var/crash/volatile*…I can fit so
many cores in here). I touched
lx brand,
zones, dladm, dlmgmtd, mdb, mac, dls,
ip, aggr,
ixgbe, i40e,
bufmod!), viona
networking), simnet,
even sdev! I
was honored
to give
a talk

about one
of the founders
of this great tradition that we call
the Unix
Time-Sharing System
. But above all, I got to work with and
learn from some truly great people. I feel like I packed a
decade of learning into three-and-a-half years.

At this point, you can’t send or receive a packet in SmartOS
or OmniOS (and hopefully all illumos distros after some
upstreaming) without crossing my code. In fact, this
blog itself is hosted on OmniOS and was delivered to you by my
networking bits. I think that’s pretty rad, but also scary as
hell (networking gods, I tempt ye not). I’ve come a long way
from recovering database developer.

But like all good parties, it had to come to an end; and it
did, on Feb 03, 2020. I was let go as part of a RIF (Reduction
In Force). It’s not a fun way to go. I’m bummed. I feel like I
was just starting to ease into my all-night rager as an
illumos kernel developer, only to have 5-0 break it up before
I could jump off the roof into the pool. I’ve looked up to the
Sun developers since Surge BoF 2012, when I watched Bryan and
Brendan use DTrace to debug latency outliers in the cloud.
I’ll never forget that evening; I had never seen two people
with such command and poise over the operating system — they
were brilliant to watch. After becoming addicted
to SmartOS
that year, I knew that somehow, someway, I wanted to be a part
of it. I wanted to join the team at Joyent and further their
mission of bringing a better cloud to the world. It was going
to be my own version of Sun, in a world where the original had
long since been swallowed up by the event horizon Oracle.

And it was just that, for a while. My first day at Joyent is
one I’ll cherish forever. Sitting in a room overlooking the
San Francisco Bay with Bryan, Robert, and Angela, with Jerry
and Patrick on the phone, discussing my potential future
contributions — I had arrived. I was exactly where I was meant
to be, with the people I was meant to be with. The lx branded
was alive
, containers
were looking more promising by the day, and I was ready to
dive head-first into the depths of the kernel I loved so much.

But as any software veteran knows, projects often don’t
survive the whims of management. No one is fired for picking
Linux (these days), but they might be for picking something
else. I already experienced this once before, as a
core developer
the Riak
. We were rigorous, paying homage to the
theoretics of distributed systems, but with a focus on
bringing that theory to the masses. So much so that our last
CEO said we had to stop doing so much “computer science”. He
meant it as an insult, but we wore it as a badge of honor. But
hey, MongoDB had a sweet API and BJSON, who cares if it lost
your data occasionally [1]. I understand
that people like to stick with what is popular. I respect that
decision — it is theirs to make. But I’ll never be a part of
that crowd. I want to use software that speaks to me, software
that solves the problems I have, software guided by similar
values to my own. For me, no project does this more than
SmartOS and the illumos kernel. It is my Shawshank Redemption
in a sea of MCU.

I don’t know what the future holds. I still believe in the
illumos kernel and the operating systems based on it (I’m not
alone). I’m going to do my best to continue working on it —
paid or not. But for now, I’ve got a mountain to snowboard,
and a winter to enjoy (hello Winter of Z). To my fellow
Joyeurs, past and present: it was an honor. I’ll see you
around the bend.
