only a few of them require programming, per se. Only a radical subset of the DH community knows how to code; nearly all are engaged in building something.
This made me rethink of how necessary we need coding or programming to learn in DH? Sometimes DH students have misconception that they always need coding to work in DH field. The other more important element to work in DH is "the ideas" of what you actually what to build, transform and create. Computational tools or even coding skills will come after that.
