Learning Infrastructure with a local Compute Cluster

In this presentation, I use a TuringPi v2 to show how you can set up an at-home compute cluster and use it to learn crucial infrastructure engineering skills.

This version of the talk was given at the 10th Edition of All Things Open in November 2022.
