RiderOfGiraffes, thank you. Couldn't find a "search box", hence the somewhat duplicate entry. The page posted today should be more useful to readers, as it has many more actionable details. The talk was given by my father.
(link at the bottom of the news page)
It would be really useful to be able to cross-reference items more easily, and then to merge discussions and comments, but I suspect that won't happen.
Anyway, interesting talk, interesting idea. Thanks to you and your father.
