I'm not sure if you actually brought in a developer... the explanation is so frustrating. Is this even supposed to be a lecture? While writing the matrix multiplication, you're stumbling over your words using just a single piece of pseudocode, and I have to figure out what you're trying to do by looking at the code myself. It's not like you're providing proper comments either. This is a very disappointing lecture.

Thank you for the great lecture.

I recommend it.

It was a great lecture! I've got a good grasp of the basic concepts of Python Flask. Thank you for the great lecture!
