Part one of a two part recording with Mark Seemann on dependency injection and rejection in F#.
Who he is, what he does. The new video site. Used to earn from C#, now earns from F# but would like to earn from Haskell; how much dev is going on in F#. Dependency rejection; side effects, purity and determinism. Impure functions. Pure and impure calling each other. Dijkstra, abstractions and monoids.
