Any courses you would particularly recommend? I always found that Udemy's vast catalogue made it hard to actually pick a course.

The pillaging will continue until quarterly earnings improve

I did Andrew Ng's old Machine Learning, Obarsky's Scala course, the Ng's Deep Learning specialization, Nand to Tetris part 1 and a small Data Science course which wasn't very good. I think my very first course was "Model Thinking" course, but I never took the exam there.

I also tried the sequel to the Scala course at one point, and the Cryptography course, but I dropped out from those after finding out they were a bit too hard - I spent way more time on the coursework than I'd intended.

But I can't say I like the direction it's taken in recent years.
