A practical QA lab on Linux

A practical QA lab on Linux

I keep Ubuntu servers and Raspberry Pi boxes for the same reason I keep test notes: they make experiments cheap. Self-hosted apps, Ollama models, deployment configs, and monitoring are easier to learn when the machine is yours and the blast radius is contained.

That lab also feeds product work. Hosting octbe.com taught me SEO, Linux services, and the difference between “it runs on my laptop” and “it survives a reboot”. The same environment is where I try automation scripts, log pipelines, and small security checks before they become someone else’s incident.

What the lab is for

• Repeatable deploys, not one-off miracles.
• Space to break things without taking production with them.
• A place to test AI tooling without sending private data to a random cloud.

Quality work is better when the tester understands the stack. A homelab is the fastest way I know to keep that understanding honest.
