Put a battery gauge on there, run MS teams, and watch it drain in realtime.

In many cases when chasing numbers, yes. In most claims of the “fastest overclock of $thing” the accepted criteria is completing the benchmark without crashing.

As promised in many science fiction novels, humanity will split into two species: Those who can think and those who cannot. Keep your kids away from LLMs and they will have an advantage over those who…

This is why you also charge possession of stolen property, and not only theft

Despite the lack of context (as is expected when gangsters like Fenwick and West get involved -- i've gotten letters from them), I will throw my lot in with Adafruit. The people who run Adafruit …

Completely garden-variety normal ARM-designed cores: Cortex-X925 and Cortex-A725

68k outliving 486 support in the kernel will be hilarious

Sound like Microsoft's given me permission to make some binary patches to return functionality I already paid for, and to share it with my 7 billion closest friends. Cool.

Yup, it is the rich who are hoarding the secrets of avoiding neutron embrittlement. And we'll never tell you what they are.

modifying source to avoid an assembly isntr isn't a fix... this need a compiler fix most likely, or a microcode fix, if possible.

Do you also install pre-alpha revisions of operating systems on your main work pc? No, you do not. Why? Because of the "foreseeable compatibility and security issues". "Well, why don…

Prior to the invention of copyright, it was not very cheap or easy to make a faithful copy of something. Books had to be type set by hand, before the printing press they had to be copied by hand. Phot…

Which is ok since it is UB to deref

No cause that requires initial alignment.

Without memcpy there is no guarantee that that line produces an invalid pointer I don’t see what spec part would prohibit that cast from validly compiling to BIC r3, r0, #3
Spec only guarantee…

For signed. Unsigned overflow was defined for a while now.
comment
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 requi…
comment
Fun story: even the latest C spec doesn’t require CHAR_BIT == 8, but it does now codify 2s complement int representation. (IIRC)
comment
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.…
