PurelyFunctional.tv: How did you get into functional programming?
Joe Armstrong: I guess the book by Peter Henderson about Lispkit Lisp did it for me.
I bought in in 1980 and implemented lispkit lisp in Fortran.
PF.tv: Very briefly, what is your talk about?
JA: Dunno - not written yet.
PF.tv: What do you hope people will take away from the talk?
JA: The idea that programming is fun.
PF.tv: Your previous talks have been about software reliability, software complexity, and interesting solutions to that. Are these related to programming the Sonic Pi?
PF.tv: What concepts do you recommend people be familiar with to maximize their experience with the talk?
JA: Download Sonic Pi and play with it. Please do this.
PF.tv: What resources are available for people who want to study up before the talk?
