Explorations

The foundation everything else runs on.

From first login to production confidence — not sysadmin training, practical Linux competence for developers and platform engineers who need to get work done.

Your company adopted it. This gets you functional.

Not certified, not expert-level — capable enough to deploy your app, debug when things break, and stop being the person who has to ask the platform team for help every time.

For platform engineers who already know bash.

Task-first, not syntax-first. You don't need to understand decorators before you can write a health-check poller. This site starts with the task. The Python comes with it.

You know how to code. This teaches you why it works.

The formal theory that makes you a stronger engineer — Big-O, data structures, FSMs, parsers, compilers. Not academic exercises; the stuff that makes you able to explain your own PR.

The tools that make working with everything else bearable.

Git workflows, editors, terminal multiplexers, and the other tools that separate engineers who fight their environment from ones who work in flow.
