at 45:40, I think d should be "minus" , not , such that gives implicit description of the plane +d=0, of which the distance to point x is given as Dist(x) = = -=ax+by+cz+d.
Answer to question at 1:02:00 (to my own understanding) Because B as the top-left 3*3 part of K is fundamentally (ww^T) if we let w be a R^3 vector having equal values as the first 3 entries of v, which is pretty obviously a SPD matrix.

This is Gold! Can't wait for the next video!
super helpful explanations, thank you!!

at 45:40, there is a typo, d should be -
at 47:00, should d be -d ?
