Infrastructure

Troubleshooting notes, configuration discoveries, packet-level oddities, DNS, email systems, and the things vendors forgot to document.

Physical systems

Electrical, plumbing, mechanical, appliance, automotive, and construction observations that deserve better than a scrap of paper.

Recurring lessons from debugging systems of every kind, including the uncomfortable number of times the symptom is not the problem.
