The Haskell Interlude

José Calderón  is interviewed by Niki Vazou and Wouter Swierstra .  José has been working on functional programming at Galois and University of Maryland.  He tells us about his research background in many different continents, his experience with teaching compilers, the relation between music and functional programming and the "Recursive Programming Techniques" book that in the  1970s captured the essence of functional programming.

Graham Hutton is interviewed by Wouter Swierstra and Andres Löh. Graham is known for his work on Haskell both in research and teaching Haskell, and in particular his Haskell book. Graham will tell us a little bit about how his book came about and give us advice for how to write a book ourselves, but also look back on his experience using Haskell and teaching Haskell in the last thirty years, and tell us a little bit about how bad the compile times were for the very first versions of GHC.
