I don't know dakimov and what his history may be (maybe it's even a language issue or that he simply doesn't "speak HN" yet - I also sometimes find myself out of touch with the culture on this site like he seems to be), but I can vouch for what he's saying. I find it difficult to read discussions about C on HN. A lot of the discussion is as if to read a bunch of kids who seemingly just learned javascript or ruby yesterday, then they go way out of their element talking about C. An experienced and competent C programmer would not be surprised by anything in these slides, except perhaps the slide about the novel use of "static", because it's an obscure C99 feature that nobody really uses (in the same way that most people would also not recognize that, for example, C99 specifies compiler support for complex numbers).
