Thank you so much for making this good learning material and for making it easily available for free and for everyone.

That was good and the first time I have learned about the 'circ' or 'circle' operator in mathematics, now need time to grasp the concept.

I think the ideal is you always use your computer, but you know you made a mistake by intuition while it's compiling.

The lecture went a bit trapezoid in the middle, but was still pretty interesting.

[brettknoss]

Is this in Pluto.jl? If so, will the notebooks be avaliable?

[GoatMen]

Julia's jit implementation is so sad. I really loved the idea of the language but it let us all down.
