Please look up Linus on Gamedev.net and sse that this post has been discussed a lot already.

Its not the first time Linus displays he's anti-social qualities.
He's probably fed up with suggestions about C++, hehe

Even though the thread seems to be about Git, they soon start talking about how C++ is useless for low level OS programming (See a couple of replies later)

I didn't read the whole thing, but it appears that there was already some kind of heated confrontation, and perhaps the spirit with which he bashed C++ was used as a way to get someone angry/upset.

Hmm, attacks on C++ have come from the other side, too - no encapsulation, no modules, no reflection et al. Linus seems to touch on something along these lines further down, too.

It's definitely an eyesore of a language in some several ways. I tend to think of it as a bit of the programmers' kitchen sink, a general wastebucket of 40 or so years of programming legacy - within which are plenty of powerful and quirky constructs with which you can flesh out your designs and generally experiment, but it attracts bugs, and makes bad habits and obfuscated idioms very easy to form.

Anyway, I think C++ is straddling a divide which is about to become a lot more pronounced in the next few years. It will probably eventually fall completely within the systems stream where Straustrup sees it, even if Torvalds is less-than-accepting of it - I seriously don't see C++ holding its own in application programming when apps are just about set to cut themselves loose of the iron entirely.

EDIT: I should say that I don't agree with Linus's idea of what a systems language is, in general, but then again I've always found the GNU/Linux scene's insistence that C is the only choice a bit obtuse.
Also, I find myself becoming more of a fan of Walter Bright.
