Off the Beaten Track: Explaining Type Errors

Last week I gave a talk at Off the Beaten Track 2018 about something that Richard Eisenberg, Harley Eades and I have been thinking about recently: namely, how to generate good interactive error explanations for programmers, especially for type errors. None of the talks at OBT were recorded, but I’ve prepared a version of my slides interspersed with (something like) a transcript of what I said.
