Felienne Hermans on Functional Excel and Graphical Languages
Felienne Hermans spent some time blowing my mind on some of the underlying functional concepts exposed in Excel. Essentially she describes Excel as a graphical language and goes through some functional concepts and how they are surfaced in spreadsheets. It then led to a larger discussion on the notion of graphical languages. It was one of the more interesting things I got to learn about at NDC London!
