Personal workspace

Short notes on systems, tools, and practical engineering.

This site collects small operational notes, configuration reminders, and observations from day-to-day work with Linux servers and web tools.

Server hygiene

Keep public services explicit, document ports, and verify changes after every deployment.

DNS basics

A single clear hostname is usually easier to maintain than several temporary aliases.

Operations

Prefer small reversible changes, readable configs, and service checks that can be repeated.
