Systems Thinking Data Salon · A talk by Jean Haley
What began as a message relay so I could work away from my desk grew one part at a time into the system that runs my home lab on a single salvaged ThinkPad T480.
The whole system, at a glance
Chat in through the relay; one live model session at the center; scheduler, observability, k3s and sensors around it; everything behind a single controlled egress.
The full story in long form, in my own words, derived from my talk notes.

The complete narrative: the design philosophy, the accidental multi-tenancy, the scheduler that gave it a heartbeat, and the observability stack that became a nervous system.

Building a Home Control Plane From Parts
How a message relay grew, one part at a time, into the control plane for a home lab.

The seven diagrams the talk was built on: the initial concept, the two-way channel, the day-one relay, the authentication layer, the scheduler, the nervous system, and the bird's-eye above.
Detailed breakdowns of the individual components, derived from active code.
I asked Rodin to draw a picture of how it perceives itself, and this is what it came up with.
Asked to draw itself, the machine rendered an anatomical plate: one watchful mind at the center of a vessel that's part ship, part ThinkPad, with senses reaching out, a nervous system of alerts looping back, services as organs, and a single tether to the world.
