Systems Journal

Plain-language notes about reliable software and operations.

A lightweight journal about operating small systems, learning from failures, and preferring understandable tools.

A small service is easier to repair when its failure mode is explicit and observable.

Note 02

Operational defaults shape a system long after the initial setup is forgotten.

Note 03

Simple backups and rehearsed recovery steps outperform clever emergency plans.
