Combining § Spaced Repetition and § Zettelkasten seems like a good idea:
Spaced repetition to memorize things that you need in your head often
Zettelkasten to hold your conversations with, keep track of ideas
There are a number of questions that need to be answered:
how I decide what goes into Zettelkasten vs SRS?
should I create Zettelkasten cards for things that go into SRS?
how do I keep Zettelkasten cards in sync with SRS cards?
My current () approach is to create Zettelkasten cards, but add a “Cards” section for flashcards at the bottom.
I add SRS cards:
for fundamental knowledge—things that other ideas build on top of (e.g., math definitions and properties)
things that I “should know,” things that help me in work
“emergency” exits—how to unfreeze Emacs, ssh, telnet, magic sysrq
