Chief programmer teams alive and well in academia
According to Wikipedia, “a chief programmer team is a programming team organized in a star around a “chief” role, granted to the software engineer who understands the system’s intentions the best. Other team members get supporting roles.” Amusingly, this set-up is alive and well in academia, and for good reason. At least my research group…

What’s better: Submit to ICSE or TSE? (Conference or journal?)

I finally figured out the appropriate German translation, and, oh wonder, it is shorter than the English version.…

Last weekend, I ventured into unchartered territory (for me) and attended the Berliner Methodentreffen, a research conference mostly frequented by social scientists. I participated in a workshop on mixed methods, where the presenter discussed different models of mixing methods with each other (“Methodenpluralität” in German). She omitted one model that I thought is often used:…

We may not know what we are doing…
From my excursion into qualitative research land (the aforementioned Berliner Methodentreffen) I took away some rather confusing impressions about the variety of what people consider science. I’m well aware of different philosophies of science (from positivism to radical constructivism) and their impact on research methodology (from controlled experiments to action research, ethnographies, etc.) I did…
