All the others are not very butthole-ish, though.

I feel like we're talking past each other. My impression was that 30% towards your living situation is a pretty decent target; what would you expect the percentage to be?

Okay, what I meant was, is rent taking 30% really indicative of a low standard of living?

Rent eating 30-40% of your income is extremely normal, isn't it? Or is that only true in the US (where it has recently become much more than that for many people)?

Probably moreso for expressing the opinion so strongly without actually knowing any of the three languages.

Edit: I'm just guessing why a different comment got downvotes. Why am I getting downvotes?

I think generally C compilers prefer to keep the stack intact for debugging and such.

Okay, yeah, I was indeed reading your original reply as a criticism of one of the people involved (presumably the security researcher), rather than as a criticism of the post title. Sorry for misunderstanding.

Apparently GCC does indeed do tail-call optimization at -O2: https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-foptimize-sibling-calls

But in that case, I'm not sure why the solution to the denial of service vulnerability isn't just "compile with -foptimize-sibling-calls."

What about Julia?

I agree with Linus's argument here. I also think the selected quotes are the main points in that argument, not just "inflammatory minor excerpts."

Not sure if this was intended as a response to me?

The bit you quoted from the post explicitly said "most x86 laptops", not "all".

it's old man screaming at cloud

Not exactly -- part of the point of that idiom is that the old man is powerless, and the cloud ignores him. But Hellwig is using his authority as a maintainer to make things more difficult for R4L with his "explicit NACK".

this drama Martin is doing in social media is pretty much pointless.

Well, maybe, and if you haven't seen it already, Linus chastised him for that. Several people have spoken up to say that Martin has done this sort of thing before.

But on the other hand, arguably it is important for people who don't read the Linux kernel mailing list to hear when things like this happen; and if Martin hadn't posted about it, how would we have known about it? Would The Register have written the summary that they did?

Martin isn’t even relevant! He’s just for the popcorn, like the rest of us! Free kernel development popcorn!

I'm not sure why he phrased things that way, because he was a maintainer of ARM/APPLE, which relies on R4L, until he decided to step down following Linus's reprimand. So no, he wasn't just an outside observer.

...do those changes proposed by the project affect the stable branch now?

Not sure which changes you mean, exactly, but the rust/kernel folder in the patch set does indeed already exist in the stable branch.
