Happened to be part of conversation recently that you did not get or the library which README.md was to obscure because it consistently kept on using those weird phrases? “Typeclasses”, “semigroups”, “monoids”, “applicatives” – they all seem so weird, so academic, so pointlessly detached from the real-world problems. But then again, they pop up here and there in conversations (especially if talk to functional programmers). So are they really irrelevant. Is knowing them is just an academic exercise or do they have a real applications? Well, you have to join this talk to see and judge it for yourself.

Intention of this talk is not to give just raw definitions of such terms as ‘monoid’ or ‘functor’. The more important question (rarely explained in other talks & tutorials) is what are the motivations behind those concepts. And this is exactly what we want to discover.

Preferable audience for this talk are people who:

want to stay relevant to the continuously changing industry
confuse their wives/husbands/boyfriends/girlfriends (“You know honey, a monad is just a monoid in the category of endofunctors”)
sound smart on the next job interview
UWAGA: pomimo angielskiego opisu, prezentacja będzie po polsku.
