Among other things, I learned one of my most memorable quips from him: "Don't put your ego in your code." Basically: don't consider attacks on the quality of your code as attacks on the quality of who you are. Learn, improve, and teach others the same.
He came off as incredibly self-absorbed and at times, borderline hostile. A sibling poster quoted him as saying "don't put your ego in your code", but in the 4+ years I dealt with him, he was nothing but ego.
I don't doubt his intelligence and obviously he's a very accomplished individual, but I just don't see what everyone else saw in him.
Notice the font size of his name, versus the font size of the students who actually wrote the book and everything will be clear to you!
How does one increase font size on HN? I feel I deserve a larger font for my username!
Except that, thank you for that YT link. A critical opinion, when well stated is worth its weight in gold.
