A Taste of Type Theory • Bartosz Milewski • YOW! 2019

This presentation was recorded at YOW! 2019. #GOTOcon #YOW https://yowcon.com Bartosz Milewski - Founder of Reliable Software ABSTRACT We use types in programming, often without realizing how deeply rooted they are in the foundations of mathematics. There is a constant flow of ideas from type theory to programming (and back). We are familiar with algebraic data types; inductive types, like lists or trees; we've heard of dependent types and, in the future, we might encounter identity types and possibly get familiar with elements of homotopy type theory. I can't possibly talk about all of this, but I'll try to give you a little taste.
