To be honest your pr and these notes are super helpful cos, otherwise I'd have been too lazy to read up the original implementation, but I can't merge it. Will make the fix soonish and credit it to you. I'll tell you a secret, nobody is good at C except for a few wizards like woz, Linus, jart, Knuth, Bellard and the like. I am also a total looser at C. I just love C. And also the base of this is mostly Karpathy's work and other awesome folks who are way better at everything than me.
