one could already add loads off a volatile and portably prevent the loop from being optimized. But there was already a lot of existing embedded code that had this sort of loop, (and more will be written as it is an existing idiom) which the

As the only observable behaviour of this_thread::yield is forward progress, because of the as-if rule, the compiler doesn't actually need to replace the loop, when running on a runtime that guarantees preemption. That's the case w

right, but the issue was that if an application was linked with a library that happened to link with a fast-math shared library, it would unknowingly bring along the crt code. Now the only way to get it is to use the fast-math flag when lin

IEEE 754 defines bit exact results for a lot of FP operations, including denormals.

IIRC that has been since split out of the flag and need to be asked for separately at link time.

Fujitsu has a long history of designing their own micro but using a standard ISA for HPC. Used to be SPARC, now it is ARM. IIRC Fujitsu were the main architects behind the SVE ARM extension.

Things get complicated when a lambda that capture by reference is capturing things that are not on a single stack frame (or a stack frame at all). Then you have references to references. You could rely on the optimizer, but the capture has

It is undemocratic when the democratically elected people wants to subvert the democratic order. Most (but not all!) democratic countries have constitutions that actually limit the power of elected people exactly for this reason. Especiall

C++11/C11 memory model and atomics provide a more well funded model to interact with signal handler. I'm not sure if POSIX fully embraced it, but it will work well in practice.

>You cannot pass a lambda expression to a function that expects a function pointer (e.g. bool(*)(int) in this example) To be pedantic, you can: as long as the lambda doesn't close over any local variable, the object will decay to a

of course doctors should not be forced, that's ridiculous, but the SSN should prioritise hiring non-objecting doctors, at least in areas where there isn't enough coverage (in the same way it should prioritise hiring other speciali

Agree about that. The question is whether all websites providing black-market potentially generous medications are being targeted or specifically just abortion pills. I genuinely do not know, this might be making the news but actually be pa

It is indeed legal, but gynaecologists can object to help for conscientious reasons (65% do) and in quite a few hospitals, 100% do object, especially in the south. So in practice access to it is not always that easy.

Agree. Unscientifically, I don't think current LLM are conscious because I don't think they have enough awareness of their own thoughts (I, again unscientifically don't believe that the context window is enough). Still, tthey

Are we really still going with the "personal security" story? I thought he had pivoted a couple of times to other, not necessarily more credible, stories.
