Thank you! I have two kind suggestions with the only intention that might make your videos more popular, which it deserves. a) Adding the key equtions above the code block. I guess most guys found these videos mainly want to clarify the concepts with code. b) Zoom in the working area. Sometime I found the font is somehow small on a 15 inch laptop. Recorder like Camtasia can automatically zoom in the area your are working with one click (not perfect but can be manually adjusted trivially).
Just suggestions, I believe you have your own philosophy and I highly supports that. The contents per se already manifest itself. Thanks again!
