For signed. Unsigned overflow was defined for a while now.

I do not see there a promise that the cast will produce an invalid pointer, nor anything prohibiting the compiler from rounding the pointer down, thus producing a valid one. “Converted” does not require bit copy. I don’t see how this interp

Fun story: even the latest C spec doesn’t require CHAR_BIT == 8, but it does now codify 2s complement int representation. (IIRC)

That cast is valid. Spec does not guarantee same bit sequence for resulting pointer and source pointer. But as the cast is explicitly allowed, it is not UB. Compiler is free to round the pointer down. Or up. Or even sideways. All ok. Derefe

I stoped reading about here: > bool parse_packet(const uint8_t* bytes) { > const int* magic_intp = (const int*)bytes; // UB! Author, if you are reading this, please cite the spec section explaining that this

If my download ever finishes i'll spin up a torrent. So far on retry/resume #12, 97.3/120GB done (i am live updating this comment as long as i can)

Libc still unaffected. Write native code. Your users will thank you

If you believe Boom, let me know if you'd be interested in a bet. I'll take the "not gonna happen" side of that for any amount.

yes, but it was rather choosy with the rest of the hardware

probably cause it is just CE 2.11? either you have seen it and seeing it again is pointless, or you do not know what CE is, and the headline means nothing to you

There are already proper procedures for doing this. If the users did something illegal, you can go after them. If you prove that somebody actively enabled or encouraged them, you go after them. But even if the app actively enabled or encour

Only a few years ago, i would have used this and donated some bucks for the effort. But apple silicon has made x86 laptops irrelevant, and i haven't owned a desktop in decades. Sad, since windows 7 is the second-best looking OS i'

I never learned to properly touch type, i have my own method, somehow, which uses two fingers of the left hand and three of the right. Spacebar being pressed too soon or too late is, sadly, common :(

In GM cars (as observed in my last few), the logic is in the head unit: "mic on -> hvac lower", while "hotword detect" uses a different "mic on" method that does not EDIT, previously "does not" abo

both forth and java would have made more sense than a custom vm. not sure why they went this way on ARM. on 6502 it makes sense though. small cpu -> custom work needed

no, but i hope someday someone will make that happen. i provide enough info and reference material

that is why it was not "static const char buf[]" ;) it was not an accident executable stacks are still common (incl on windows with some settings), and sometimes they are required (eg for gcc nested functions)

Cute, but Rice's theorem remains, and while they translated every byte as code, still no handling is possible for char buf[] = {0xB8, 0x2A, 0x00, 0x00, 0x00, 0xC3}; return ((int (*)(void))buf)(); static translation is only p

That is a gross misrepresentation of the situation. Old batteries' internal resistance rises and they become unable to deliver high current. If you try, thanks to V=IR, the output voltage will droop and you'll brown out. Limiting
