Pathways
Guided routes through the material with a single goal in mind. Where the Explorations are a library you browse by topic, a Pathway is a curriculum you follow start to finish — and it deliberately crosses site boundaries, because real goals don't respect them.

How Modern Software Really Runs on a CPU
16 steps live · 5 sitesFrom machine code to Kubernetes — the same problem, solved again at every altitude.
You write code, deploy it with kubectl apply, and a container starts somewhere. This pathway is what actually happens in between — from the CPU executing machine instructions, through the OS process model and Linux isolation primitives, to how Kubernetes decides where your workload runs and how much CPU it's allowed to use.
Put Your Kubernetes App on the Internet
13 steps live · 4 sitesIt runs in the cluster. Now give the world a URL that reaches it.
Your app is deployed and healthy — but only you can reach it, through kubectl and port-forwards. This pathway covers everything between your Service and a stranger's browser: how DNS finds you, how TLS earns the padlock, and the Gateway API front door that ties it all together.
How APIs Actually Work
10 steps live · 3 sitesPast curl and Postman to what is really happening on the wire.
You use APIs every day but the under-the-hood picture stays fuzzy: what an endpoint really is, where the front-end/back-end line sits, and how it all gets secured. This pathway walks from the core concept, to how an endpoint is exposed and protected, to seeing it live in your terminal.
