You want to replace Agile with CSP? Interesting . Why not replacing Agile with FSMs, though? Or continuations? Or monads?

I dislike UB, but I do at language level. When LLVM is reached, UB can only have and only be continued to be removed, never added (from a global point of view, applying general as-if rules a compiler can always generate its own boilerplate

I thought the compiler was free to pretend loops without side effects always terminate, and in that sense it is already a "correct" optimization? Or is it only for C++, I'm not sure?

Maybe in this context, making a "hard choice" is accepting that something like 0.3% of the world population dies? Historically we saw worse and recovered, while trying to engineer something with no guarantee it won't be massi

Is there a guarantee it would not associate with other viruses (possibly other strains, or even something worse?) And the lack of testing to "save time" actually does not look like a good idea for a live virus you want to give to

If you want that much to program in a functional style, maybe use a functional language. It will probably be more efficient, compile faster, and be easier to maintain.

The number of ITU standards is HUGE and some of them are good, and some of them are even still in use. Given the volume, they are necessarily quite heterogeneous and designed by distinct groups of people. Likewise for the IETF RFCs. Both at

It depends, but I agree that this is a crazy hard problem to address correctly and not create dystopian side effects or even just risk that. Imagine you need some QoS on a few streams for serious and useful purposes (telesurgery comes to

Yeah, and the reaction of the IETF is really weird. They feel threatened. And they would not feel threatened if the project was pure garbage. And their points are weak. This is basically: this is OUR standard and WE are in charge of this pa

You would be surprised about what is happening in modern computers. I don't know about REP SCASB, but IIRC, REP MOVSB is now an insanely efficient way to memcpy on last Intel microarchs (not necessarily always the fastest, but really f

There is no answers if you don't specify tons of parameters, like the number of element, prior memory fragmentation, etc. 200x can be a reasonable outcome. So can be 3x in other conditions. As a rule of thumb I now consider that a co

The basic speed up will not even be because of vectorisation. It will be because of caches.

Or you would have the Ethernet situation: a new better tech that is called Ethernet while having mostly nothing to do with the old one, and people migrate to it, and the old tech is eventually not used anymore.

We don't usually call a disease that can easily evolve to pneumonie "a cold". And your focus on the supposedly low lethality is misplaced. Way more people need a stay in an hospital (sometimes short). This disease has the pow

I said "during", and "focus". Right out stating to the world "oh my god the world is overreacting, this is not such a big deal, and the best opportunity in your life to get rich for completely abstract reasons"

For some young people, it might ressemble to a "bad cold", and some people might even be completely asymptomatic, HOWEVER: - in France 50% of ICU patients are under 60 - this is really the wrong message to pass - for some peop

That standard argument is a myth simply used to shape opinion in the context of a shortage of masks, to redirect the existing one to health care workers. In countries where the epidemic is controlled, pretty much everybody wear masks, inclu

Well, in some frequency ranges, using a conventional radar, yes. And for some applications, that is important. But even state of the art modern stealth planes are way less stealth than some people expect.

Exp is the simplest, and works very well with this virus. To not get exp you have to basically eradicate it (can be done locally with strict lockdown measures, but one day or another you will have to lift them...)

The "new" AMD attack depends on lack of already existing spectre mitigations. If I understand correctly, this one is a real new one that works against a correctly patched system.

It's even worse than that. If it is believed that the plane is only suitable for American pilots, it should not even be sold outside of the USA...
