Carl and Richard talk to Neil Danson about his experiences with F#. The conversation starts off connecting Carl's thoughts on neural networks and a listener question - so what is the role of F# in the big data analytic world? Neil digs into how F# has permeated all types of development in the .NET world, even WPF! There's also some serious discussion about quality of code in F# and how Bob Martin's SOLID principles can be applied to functional programming.
