About
Matthew J. Harmon. Two decades in information security: incident response, threat intelligence, risk assessment, and the unglamorous work of making controls actually hold.
This site is the archive — talks going back to 2010, the tooling that came out of that work, and the occasional argument. The name is a joke that got less funny over time.

This site
Static, built with Zola. No trackers, no third-party requests, no fonts fetched from anyone else’s server. Two visual skins ship with it — the toggle is in the header, and your choice is remembered locally. Everything is also available as an Atom feed.

Publishing without downtime
Every publish reboots a unikernel that serves 34 sites. Five gates stand between a bad build and everyone's traffic — and each one exists because something got through.

The itys.net unikernel
This site is served by a Go program that is the operating system, with the whole site compiled into its disk image. Thirty-three sites share it.
