Handwritten notes are much more effective when having conversations and taking notes. Programmers often pull out their laptops or phones when talking with eachother, but when talking to scientists, they always seem to use paper, and so I've taken up that habit as well. (using bullet journalling mostly)

I then transcribe into a collected note markdown document in github, which forces me to complete the first spaced repetition of the information, which is a huge help in remembering it.

Then, I keep all notes in one document, so that when I review todos for the day, I have to scroll past / search through the other ones, completing more spaced repetition cues.
