This is Snacks

A snack is short and explains one idea. It ends when that idea has landed.

It is not a chapter of a long course cut into pieces. It is the opposite: it is written whole and it stands on its own. If you read exactly one of these, that one still pays.

What you are reading right now is a snack. This one.

programprogram: A complete offering on one subject. "Working with files" is one. There will be more, about matters with nothing to do with this one.
bentothe box: A box with compartments: it decides which snacks are in, in what order, and which ones are open. Each snack is eaten on its own; somebody arranged the box. A snack does not know which bento it lives in: the bento places it, and the same snack can sit in two.
snackthe idea: One short idea. It is the unit you read and the unit you share.
beatthe block: Each block inside a snack: a stretch of prose, a figure, or a question.

Four levels, and these are the only four words.

ProseThe argument, in a narrow column so it reads without effort. Short sentences for what matters.
FigureA drawing you play with, not an illustration. If it has buttons it is because there is something to try.
QuestionOne only, at the end. Not an exam: it is how you know the idea landed. That is why the answer tells you why.

Three kinds of block, and not one of them is decoration.

What makes a snack a snack and not a chapter?

One idea at a time, and always something to look at.

Where to start

A bento is an order: which snack comes first and which comes after.
