The Ghost Operator's Signal
It usually arrives out of nowhere. A person claiming to work for a domain registration center or network authority says another company wants to register your brand name as several .cn domains – maybe example.cn, example.com.cn, example.net.cn, and so on.

Modern dashboards look impressive. Yet, when systems fail, we return to the shell.
The basics – ps, grep, awk, ip, nmcli, sed, uniq, sort – never left.
They are still the quickest path between question and answer.
This post is not nostalgia. It’s about precision, control, and speed.
The old tools survive because they do exactly what we ask.
Continue reading “The Forgotten Basics: Why ps, grep, and awk Still Beat Fancy Tools”The UNIX philosophy is still alive: one task – one tool.
Backups feel safe, but they are only useful if you can restore them when the unexpected occurs.
Many operators treat backups as a safety net; few test that net for real resilience.
When a stakeholder looks at the org chart, they see a line of titles that rises like a ladder:
junior engineer → senior engineer → lead → architect.
The assumption is simple: tenure equals expertise.
That ledger is wrong.

Code is the shield and the blade.
A single line of script can stop an exploit or create one.

We used to think of privacy as secrecy.
Something for spies, activists, or people with something to hide.
That mindset doesn’t fit the world we live in anymore.
Today, privacy is choice – the ability to decide what others see about you, when, and how.

There’s power in owning your words.
At Tom’s IT Cafe, we built a fully self-hosted Matrix Synapse server – secured, encrypted, and tuned for reliability.

SOPS restores the signal.

Sysadmins.
DevOps.
Developers.
Operators in different uniforms.
Ghosts know that secrets are critical.
You can’t let them sit or travel in plain text.
Ansible Vault is the blade of the Operator.
Write once.
Execute unlimited.
The Ghost Ops way.
Variables – loaded.
Templates – locked.
Tasks – trained.
Playbooks – executing.
Roles – fixed directory structures of Ansible code.

Variables – loaded.
Templates – locked.
Tasks – trained.
Ghosts may notice – we’re flying low with plain text variables – for now.

Logic and data separated.
Variables are loaded.
Dynamic configuration files? Templates are your blades – fed by variables.
They support logic.
Loops.
Conditionals.
Ghosts don’t over-complicate.
Clarity keeps templates sharp.
Hostnames.
Network addresses.
Ports.
Filenames.
They change.
They’re variables.
Modules are small working horses.
Tactical code units. One module. One function. The UNIX way.
Clear Python code.
You don’t need Python – modules are abstracted to YAML.
