This blog post covers how we virtualized NVIDIA HGX B200 GPUs using open-source software. It talks about VFIO passthrough, QEMU PCI topology fixes, large BAR boot stalls, and Fabric Manager partitions.
In this post, I demonstrate the optimal workflow for creating new Debian packages in 2025, preserving the upstream Git history. The motivation for this is to lower the barrier for sharing improvements to and from upstream, and to improve software provenance and supply-chain security by making it easy to inspect every…
The research roots of finding “optimal routing” networks trace back to the late 1970s. Mathematicians defined special kinds of networks called “expanders“. These are graphs with strong connectivity properties guaranteeing no subset of vertices can be isolated from the rest. In 1976, Leslie Valiant gave one of the…
I just removed myself from every OpenStack mailing list and meetup. I’m sure I’ll still use it, but I don’t see myself as part of that community any longer.

A comprehensive tutorial on how to build a personal professional website on a Raspberry Pi.
Transactional databases have long been the most critical component of application design. Why? Because a steadfast database is generally the ultimate enforcement point for correctness in a messy, distributed world. Without them we’d overpay and undercharge. We’d lose riders trying to get home from the airport, and…
Initial Gravwell testers did a lot of home monitoring with the software and wanted to get licenses for their friends and colleagues but Gravwell was built for larger enterprises and our pricing model isn't set up for home use. All of that changes with the Community Edition...
Our journey investigating a months-long issue and what we learned from it
Throughout my career, I’ve developed some opinions. Some have worn particularly deep ruts, reinforced by years of experience. I tried to…
Moving off of Github and onto my own public Git hosting.
