Dear Haskell Mailing List, we are looking for participants for a ~30 minute interview on bugs, debugging and bug-classification in Haskell. There is a big body of literature on this for e.g. Java, but Haskell might has its own challenges (or hidden similarities), and we hope to map out valuable research that helps practitioners. Your opinion really matters, and I want to encourage anyone to reach out to us even if you don't feel "experienced enough". We don't have a measure for what a real Haskell programmer must do, and if you are coming from a different paradigm and background your insights are very valuable too. The only requirement is to use Haskell regularly enough to encounter and fix bugs, preferably in contact with other humans. This research is currently conducted at the TU Delft and underlies its Data Protection and Ethics standards. Participants from Industry are particularly encouraged and it is possible to redact the transcript post-interview to ensure only things are shared you are comfortable sharing. We will not share interviews or transcripts - only excerpts anonymized and gathered in a codebook. Looking forward for all your Bugs!
