I don't keep a general knowledge repo but recently I realised that I've gone through a bunch of books on math, statistics and machine learning that approach the same topics in different ways. I started a "knowledge repository" just as a way to solidify what I already know. I throw in a bunch of definitions, theorems, formulas, algorithm explanations - from easy and obvious stuff to more advanced concepts. I use Jupyter for this because the markdown is simple but still supports MathJax/LaTeX equations.
