For the new Haskell Interlude, we sat down with Edward Kmett. Ed is the Founder and Chief Scientist of Positron AI. More importantly, he’s a legend in the Haskell community for authoring many, many popular Haskell packages, first and foremost lens - and generally turning up the abstraction level to 11. We talk about design principles for Haskell libraries, category theory, cache-oblivious algorithms and his current work involving Haskell, C++, and FPGAs. Ed talks fast, so strap in!
