The examples in the article don't bother me much, but I've noticed that I struggle a lot more when it comes to linear algebra. It might be due to less experience, but I can easily lose track of which things are scalars vs vectors vs matrices vs tensors. I'm noticing it right now working through various tutorials on neural networks... I get the concepts easily but when I sit down to implement, translating the notation into code is a lot more difficult than the scalar functions I'm used to.

Some authors use conventions such as boldface for vectors and capital letters for matrices. There are also often conventions around different types of e.g. scalars. a, b, c are typically used for different things than i, j, k, within a text.

Matrix and trace derivatives became a lot easier when I started doing it all in index notation.
