The other book looks rather math heavy, but a quick glance through I think I remember how to read everything that's going on there.
When I saw the title of the lecture, my immediate reaction was, "oh no, this could be such a train wreck." But then I saw who was delivering that and changed my opinion to, "okay, I'd like to hear what he has to say on that topic."
Because I'm staying at a hotel right across the street from the convention center, I can apparently connect from the little patio area where there are tables I can use to work on stuff between things I'm interested in. There's a roasting lecture from a consultant based not too far from me that I plan to check out soon.
It looks like the situation with the mis-delivered coffees is getting sorted out. It'll probably still be delivered before I'm back home, but my staff will likely not do the product development work on those so I'll have that waiting for me first thing when I get back. I'll probably also have some coffee samples from other suppliers to process.
