// from zero
Null is not empty.
It's the state before a system exists. Everything starts there. I build systems — not just software. I show you how. From zero.
// start here
Linux, terminal, backend fundamentals.
Most tutorials skip the foundation. I start exactly there — the part everyone assumes you already know.
Linux
The system your code actually runs on — processes, permissions, packages, and why the server does what it does.
Terminal
Here's the command, here's what it does, here's why. One concept at a time, no prior setup assumed.
Backend fundamentals
HTTP, DNS, databases, deployments — the moving parts behind every running service, connected end to end.
$ ss -tlnp # which ports are listening, and which process owns them
$ df -h / # how much disk is actually left
$ journalctl -u caddy -n 50 # what the service last logged
// series
Two running series.
Short, concrete pieces — published on the channels below.

//log
A build-in-public log: what I am building, what broke, and what it taught me — as it happens.
