An Open edX learning platform running on my own Talos Kubernetes cluster, with an external MySQL database and one HTTPS front door. Built to turn real homelab work into courses. The first, SEC101: Patching Under Pressure, was drafted from the PHP2Shell incident on this site, scrubbed of every internal detail, and reviewed before it reaches anyone.
This is the short version. The full story — what is under the hood, the gremlins it took to get standing, how course one was built, and the pipeline that turns every project here into a lesson — is on the blog.
