Something I've been grinding on lately. Learning the backend infrastructure that is literally running the AI future.

Still early but already building real things. Here's what I've done and why it matters 🧵

[Alberto Roldan @ValorFatalis]

AI needs somewhere to live and someone has to build it.

That's what I'm building toward.

Next up: Git & Version Control.

On real bare metal hardware. Not a sandbox.

Doing this has made one thing very clear about the AI era:

Every LLM runs on Linux.
Every model ships in a container.
Every GPU cluster runs on Kubernetes.

The demand for infrastructure engineers isn't shrinking. It's growing.

Spirit Airlines collapsed at 3AM on May 2nd. I just pledged to help build Spirit 2.0 — a people-owned airline. One member, one vote. Join us.

I wrote six scripts this week going through bash fundamentals — hello world → variables → conditionals → loops → functions → error handling.

Every single one starts with this header now.

Small habits. Production mindset from day one.

Most bash scripts are missing 3 flags that prevent serious production damage.

Here's what they are and why they matter 🧵

Every professional bash script should start with this:

#!/bin/bash
set -euo pipefail

Three flags. One line. Here's what each one does.

Three flags. One line.

The difference between a script that fails safely and one that causes silent damage in production.
