You put a lot of effort into this. What makes you believe it's important to consciously remember things we learn? Maybe the knowledge is supposed to seep into our bones.
Maybe it's enough to record, find something when we need it, but not necessarily remember it. What proof do you have that remembering everything doesn't come at a cost?
I meant "find something when we need it" and remember it to be the same. I'm not trying to create a photographic memory. Short term memory is limited, and it requires repetition for something to sink into long-term memory.
How often have you looked something up (e.g. "how do I cherry pick in git?") only to forget it and then 2 months later to look up the same information again? For this we take notes.
I'm working on reducing the need to re-do the same process again and again, to making learning and remembering more efficient.
As a first step, I created http://www.codingbrain.com. It's a knowledge management app that integrates with your markdown notes.
I too posted on HN without much feedback https://news.ycombinator.com/item?id=10464525
However, I think codingbrain tries to do too many things at once and I have plenty of sub-ideas which I plan to implement in 2016
