Some good points in this list although I'm not in full agreement with everything (especially the one about the lack of usefulness for TDD). The importance and the impacts of the tooling is often underestimated indeed. The last two random opinions about mocking and overtesting are very much true as well.

Very interesting piece. Goes in length about the UNIX history and the evolution of POSIX. It also highlight its limitations and where the design needs to evolve.
