My impression after a quick once-over is that there's an order of magnitude too little linear algebra in this. Can't have 3D video games without it, can't do large parts of machine learning and statistics without it, etc etc.
It says it's an early draft, and the lack of a coherent path in the Linear Algebra section (currently final section) plus only two sub-chapters makes me think it's under work atm.
I also have not a clue what I'm talking about with math (sub-highschool understanding) so I could be very mistaken about the path thing.
Came here to say this. I think he is focusing on the math that "typical" coders need without any emphasis on what ML practicioners need. Nevertheless I agree more linear algebra should be included.
I think that a course like this should really prepare you to be able to go and look things up yourself i.e. you only need enough linear algebra to recognise what it looks like, then you can go and read one of many excellent linear algebra books.
If you want to do video games you'll need to read something else anyway, so better to get into the habit now.
