The #Haskell #Unfolder is back! In tomorrow's episode, we'll take a look at #CUDA and write some simple functions in it. We'll also show how to interface from Haskell to CUDA and how to use QuickCheck to test CUDA functions from Haskell.

New episode of the Interlude is out! This time with @tomjaguarpaw. He talks about stability of both GHC and Haskell libraries, effects, and strictness, and the premise of functional programming: make invalid states and invalid laziness unrepresentable!
