Creating Debian packages from upstream Git
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…

Flat Datacenter Networks at Scale at Amazon
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…

Goodbye, OpenStack
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. When I was at DreamHost, I really felt like part of that community and that I could help make it better. However, in the three years since I’ve left DreamHost, I…

Modern Transactional Stack
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…

Gravwell Community Edition: A Splunk Alternative Built with Go
