I have noticed the update but I fail to understand his irony. If he did not suggest to Zuck even indirectly the idea of News Feed who would care about that post and why?
“Zuck [...] went ahead and built Facebook, and just to prove how useless everything we teach about efficiency and careful software design in CS161 really is, he implemented it in PHP.”
That is a good one. I end up having the thought "damn, a solid implementation of this would really be worth something" when merely skimming half the research papers I come across.
