A small collection of notes, references and documentation.
This site hosts a handful of internal notes and reference material. Content is kept intentionally minimal and is updated from time to time without notice.
Everything here is static — no accounts, no tracking, no cookies.
A few commands that come up often:
# check the current time on the server
date -u
# show listening ports
ss -tlnp
# follow a log file
tail -f /var/log/app.log
All systems normal. If something looks broken, it is probably being edited right now — try again in a minute.
