If this is the talk I think it is, I can say it helped me greatly as a programmer. I'm one of those 'homegrown' programmers with no formal education, and I'd probably horrify some of you with my work. But I'm learning, and very aware of my deficiencies.
What I loved about this talk is that it seemed more a 'philosophy of programming' thing, where a lot of what he said applied even to my shitty programming, and (hopefully) even improved it.
