Meta note: I'm submitting this again, and don't think of this as a dupe, because I think the transcript/blog form is much more engaging than a video (and by accounts on the video thread, the transcript may be the better form here even if one likes videos).

note that the authors own submission was marked as a dupe of the video: https://news.ycombinator.com/item?id=16051337

Ok, since people seem determined to resubmit it we'll mark this one as the dupe and revive that one.
