@kcrca on a lighter note - I have a question regarding the research on defect density:

https://www.leshatton.org/IEEE_Soft_97b.html

I enjoyed Les' approach (stumbled across the paper in the art of unix) but haven't found anything that followed on this theme; are there any "modern" papers that take a similar, empirical approach to component size and defect density, particularly w.r.t. subroutines/functions?
