Software engineering primer for non software engineers
With AI providing a route for people without software engineering backgrounds to produce code, I figured giving some context on the important parts of software engineering would be useful.

Tracking value for your effort
Spoons are a representation of energy available to each person. To use spoons more effectively, insight into how spoons are being used can help optimise high-reward tasks.

First time in a long time, I've published a Derw release!
Tooling around Derw has been rock-solid and reliable - like bach (test lib), coed (v-dom).
There's many things I could improve. Returning to a project after a time away brings fresh inspiration and prioritisation.
