What I've written also has a connection with productivity systems like GTD (which I don't use personally but serves to illustrate my point).

Many if not most people on HN are knowledge workers. For us especially, many tasks in our inboxes are non-actionable. E.g. a link you stored that teaches a great trick to use your editor, or an elusive shell one-liner you came up with.

What to do with these? A good productivity system should also include a knowledge base, so that those non-actionable bits of information that have future value can be easily stored and later retrieved. Here they explain it better than I do: https://praxis.fortelabs.co/gtd-x-pkm-8ff720ef6939/

A further tweak is to force spaced repetition on those knowledge bits you want to be able to learn by heart. In Emacs, you can achieve this by simply tagging them for later org-drill (spaced-repetition) sessions.

As a student I used to do this with pen & paper. I would patiently deconstruct books into extremely long lists of items that included definitions, theorems, corollaries, demonstrations, and whatever concepts in the right order. Then I recalled them during repetition sessions. Doing this with a spaced-repetition algorithm is a much more efficient way, as you focus your effort on hard stuff and you time sessions appropriately to maximize the chances of learning it.
