If it needs to be said, it’s because compensation isn’t merely about the [...]

The singular urgency of Ava DuVernay’s 13th

On Sunday afternoon, I was on the phone with one of my Oxide co-founders, Steve Tuck. He and I were both trying to grapple with the brazen state-sponsored violence that we were witnessing: the murder of George Floyd and the widespread, brutal, and shameless suppression of those who were demonstrating against it. Specifically, we were [...]

The soul of a new computer company

Over the summer, I described preparing for my next expedition. I’m thrilled to announce that the expedition is now plotted, the funds are raised, and the bags are packed: together with Steve Tuck and Jess Frazelle, we have started Oxide Computer Company.

Transceivers: The Device Between the NIC and the Network

One of the stories that has stuck with me over the years came from a support case that a former colleague, Ryan Nelson, had point on. At Joyent, we had third parties running our cloud orchestration software in their own data centers with hardware that they had acquired and assembled themselves. In this particular episode, [...]
