I discovered during my Wednesday trip to the MathWorks that they do extensive code reviews in house. Coincidentally, Guido van Rossum sent mail to the Python 3000 list the next day saying that the code review tool he built for Google isn't going to be released, but one designed to work with Subversion is, and Christian Hammond offered free Review Board hosting for Summer of Code projects. The study that Smart Bear Software did at Cisco convinced me that code reviews can actually work (I was sceptical for a long time, as I though they fell into the "nice, but people won't actually do it" bucket). Maybe their time has finally come?
