Time to write a game theory test

All else fails I can go with this: "Submit a number between 0 and 100. Everybody who jointly chooses the highest number will get a mark of 0, everybody else will get the mark that they chose"

Programming languages train you to not want what they don't provide, which is why programmers should learn a wide variety of different styles in order to not take any shit from language designers

@pmidden I normally call it "writing Fortran in Haskell"

@flippac @profdc9 You seem to be confusing the situation in ~1933 (when everyone was trying to get people out of Germany by whatever means they could, and scientists had more resources than most people to do so) with the situation in ~1946 (when the USA and USSR were fighting each other over the spoils of victory)

@tito @joey Sorry yes, I meant to say "polymorphic dependent type theory". It's one of the last chapters in the book (and it has prerequesites on multiple earlier chapters that I already can't understand)

@julesh What is polymorphic dependent types theory? One with a universe?

@joey What I actually mean by it is the (0, infinity) fragment of QTT. I have no idea yet how that relates to the thing that is called polymorphic type theory, which for example is the title of one of the later chapters in Jacobs' categorical logic book

Dependent optics is a research project that became a meme, and categorical cybernetics is a meme that became a research project
