01 / inventory
System inventory
Hostname, kernel, OS, uptime, storage, and a small memory snapshot before troubleshooting starts.
./system-inventory.sh● /sudo-dev/work
Things I
have built.
A short index of work that has a name, a machine, or a folder behind it. The field notes carry the long version; this page keeps the useful tools close by.

Projects and systems
01↗02↗
Home Assistant / Thread / Zigbee
Home automation that grew from a garage door
Home Assistant runs on an Odroid M1. Zigbee2MQTT uses separate radio hardware, and a 2024 ESP32-S3/H2 build tested a wired Thread path.
macOS / WebRTC / GL.iNet
SuperSpock
A native macOS client for the GL.iNet Comet RM1. The Pion/WebRTC path now negotiates and receives video; input wiring is still unfinished.
// scripts / systems
Small tools that save me twice.
From the notebook
The small scripts that turn repeated chores into commands. These helpers are deliberately boring: they inspect a machine, check a path, or show what is listening. They do not install packages, rewrite configuration, or quietly “fix” anything.
02 / network
Network check
DNS, HTTP headers, and one reachability check without turning a name-resolution problem into a guessing game.
./network-check.sh sudo-dev.com03 / sockets
What is listening?
A compact view of TCP listeners. Useful when a service says it is running but the port tells a different story.
./listeners.sh04 / logs
Recent errors
Read-only recent error messages from macOS unified logging or Linux journalctl, with output capped so it stays useful.
./recent-errors.shWhat these do not do
No credentials, private hostnames, IP addresses, package installs, service restarts, or automatic fixes. Read the output before sharing it; machine names and addresses can still appear in otherwise harmless diagnostics.
