Congratulations on your book. I've always wondered about the power of logs produced by the VCS(Version Control Systems) we use, at work or otherwise. And it is really interesting to see a book to that effect.
I have already downloaded Code maat and am gonna have a spin at it.
But we'd love to know what were some of the interesting(most complex) problems that you encountered when working with larger codebases than against those smaller in size with a fewer collaborators?
