Jörg W Mittag
Not a software developer in the sense that I write software as part of my job or otherwise get paid to do so. Also, not a developer in the sense that I write software for others.
I write software for myself, often for no other reason than that I want to. (What I call recreational programming.)
My current go-to language is Ruby, but I’m interested in all sorts of other languages as well: Newspeak, Seph, Ioke, Self, Io, Slate, Reia, Cobra, Fortress, Sapphire, Haskell, Scala, Clojure, Racket, Go, Fancy, Poison, and many more.
