Dear all,

I’m happy to announce that we’ve released four video courses about different topics in Haskell, at https://academy.47deg.com/collections/haskell

Introduction to optics (beginner)
Discovering functors, monads, and applicative (beginner)
Type level programming (intermediate)
Generic programming (advanced)

As far as I know, this is some of the first content in video about the more advanced techniques in the language, like data type promotion or constraint kinds.

I hope you all enjoy it! We're happy to hear any feedback from you :)
