A quiet place for useful notes
Jing Online is a personal technology notebook. It collects short essays, working notes, and lessons learned while building and maintaining small software systems.
The topics are deliberately practical:
- Linux services, networking, and observability
- Automation that removes repetitive work
- Static sites and lightweight self-hosting
- Notes on tools that are useful enough to keep
This site is written for future me first. If a note helps someone else avoid an afternoon of debugging, that is a welcome bonus.
There is no publishing schedule. New articles appear when a project leaves behind a lesson worth keeping.
