Ask HN: What are the MOOCs you have taken in 2018? Which do you recommend?
I would recommend Financial Markets
https://www.coursera.org/learn/financial-markets-global
Another great course I'd recommend is Big History[3]. Like nand2tetris,it gives you a great overview of the entire history of our being. From Big Bang to 2018.
Also, I am looking for some great online courses on Distributed systems. It would be good if assignments are challenging and where you have to write a lot of code.
