I wonder if it does anything useful at all, since it -O9 is not defined, unless the compiler is some kind of special version.

  IIRC, the code is actually `if O>2` or so; 3 and up are literally identical. EDIT: Per https://wiki.gentoo.org/wiki/GCC_optimization#What_about_-O_levels_higher_than_3.3F https://wiki.gentoo.org/wiki/GCC_optimization#What_about_-O_... it's `enabled = (level >= 3);`

It puts the article in a different light. Makes you wonder what else he is incompetent or negligent about. In this sense it does hurt: it hurts him, it makes him less credible.

  you realize who the author of the article is do you?
  - johnisgood 8y ago
    What are you trying to say? That because he is an authority figure to you and perhaps to other people, it is somehow OK to be ignorant about certain things? Last time I did something similar it was due to sheer ignorance and placebo. It might be a bad mistake, or a terrible habit, but it is what it is. It is silly regardless of who it comes from. :)

      He is competent, and he wrote a blogpost to share something he knows on the web. It's a bit goofy to start claiming things about a character you don't know from a free publication.

        Let me repeat: it is silly regardless of who it comes from. Everything else is irrelevant. You appear to be biased to the point of completely ignoring everything I have said. I get it, you like him. It does not change anything. I merely suggested the possibility that he might be negligent or wrong about other relevant things. Do you think that this is impossible?

        The author is competent and not at all silly. And the author explicitly stated what -O9 does and why he used it. > You appear to be biased to the point of completely ignoring everything I have said. This is in violation of you usage agreement with ycombinator. > I merely suggested the possibility that he might be negligent or wrong about other relevant things. No, that's not true. > Do you think that this is impossible? Strawman. I see that you created your account just a few days ago ... you might want to be careful with it. In any case, I won't be engaging with you further, and I doubt that I'm the only one.
