Usenet over NNCP

Usenet, of course, originally ran over UUCP in quite a few cases. Since NNCP is quite similar to UUCP – in fact, you can map UUCP commands to NNCP ones – it is quite possible, and not all that hard, to run Usenet over NNCP. In fact, in a number of ways, it works better than Usenet over UUCP! Introduction to NNCP…

For remote access to them I’m more commonly authenticating to the Kube API to spawn a privileged ephemeral debugger pod rather than accessing the host directly. I have little need for host access even for the…

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…
