Introduction to Kubernetes — Part 1: Get Something Running, Then Understand It
Deploy something first, understand it second. This course skips the architecture lecture and starts with a working app on your screen — then uses what breaks along the way to teach you what a Pod is, why Deployments exist, and how the pieces of a cluster work together.
Writing Principles
A hands-on course drawn from Roy Peter Clark's Writing Tools, teaching one writing principle per lesson through misconception-busting and real craft history — for anyone who wants clearer, more deliberate prose.
Introduction to Go
A hands-on tour of Go for programmers coming from other languages — syntax, types, concurrency, and the standard library, taught by building small working programs.
Astronomy Level 1
A first look at the sky for anyone. Meet the Sun, the Earth and the Moon, then find out why we have day and night.
Astronomy Level 2
Back to the sky, a step deeper. Starts with the year - exactly how long it is, the leap-year rule, and how to write that rule in Python.
