On Thursday morning I merged a security fix from the agent after 71 CI checks passed (kairos#4569). Before noon, every pull request that ran CI after it was red, and so was the post-merge run on master.

A colleague asked me this week how the part of my agent factory that reads GitHub mentions actually works. He wants something similar for his own repos.

The netboot server for my lab moved from my Mac to a Linux box this week. The agents did the migration, with a few back-and-forths, and the one thing I did myself was point DNS at the new machine. Then I opened the dashboard and everything was already there: my data, my login, the same certificate. Realizing I had not had to interact with either machine directly was a little crazy.

In "The Birth of My Homelab" I mentioned a new project called Mowa, short for MacOS Web API, and said more would come in a follow-up post. That was August 2025. This is the follow-up.

Kairos is at 100% on the OpenSSF Best Practices badge, at the passing level. I checked the project page directly rather than take an internal report's word for it: badge_percentage_0: 100, badge_level: passing. The rest of the week went to supply chain fixes, maintainer lifecycle documentation, and closing out the monorepo consolidation.

Last week ended on 4.2.0 shipped and a reviewer agent reading every change before I do. Both held. riscv64 moved the most this week: it now builds on every push instead of only at release time, and there is a public invitation out asking anyone with real RISC-V hardware to test it.

I was putting Home Assistant OS on a spare Raspberry Pi 4, booting off a USB SSD, with an HDMI capture card plugged into the board so I could watch the boot on my main monitor. I powered it on, console output started scrolling, and about four and a half seconds in the screen went to NO SIGNAL and stayed there. Every boot attempt did the same thing.

Last week ended on a version that had shipped but not released, and a review load I was not keeping up with. Both moved. 4.2.0 is out, reset works again on non-UKI installs, fork pull requests finally get CI, and there is now a reviewer agent reading every change before I do. 34 changes landed against Kairos this week, up from 19.

Last week I wrote that I wanted to get the agents working on actual Kairos tickets, and that the next post would either have results or another pile of postmortems. I'm happy to say it has results. It has a few postmortems too, but the results came first this time.

I picked up Ruby because of how expressive it was. Writing it just felt nice, in a way that other languages did not. Later I found out that was deliberate: Matz designed Ruby so that programmers would enjoy using it. I then spent the better part of a decade writing Ruby and enjoying it.
