How I got my AI to do jobs from a text on my phone
I nearly replaced my whole AI setup with a shiny self-hosting agent — then added the one piece I actually envied instead: now I text my always-on computer a job and it runs, hands-free.

Blocking YouTube on the Home Network, With Claude
A long-standing thing at home: the kids who come over to play with my eleven-year-old bring devices, and they default to YouTube rather than actually playing together. Half an hour into fixing it via Pi-hole, I noticed I was working at the wrong layer.
-
The Agent Never Had My Judgment
A stranger emailed me last week asking about an exercise bike I'd never owned. I knew it was a scam in two seconds and moved on. Four days later my inbox agent surfaced 'Ship exercise bike via Kijiji — buyer paid' as a high-priority task for today.

Claimed Two Open Source Projects That Weren't Mine
