it depends what the purpose of grading is. if the people is to purely assess, grading question by question is better. if the purpose is to provide feedback, knowing how the student did in general can substantially help with identifying what to emphasize

no (in both directions). lots of np/exp problems paralize well and you can be in NC and parallelize really inefficiently (e.g. you can get a 10x speedup, but you need 1000000x the hardware). the better framing is that NC is the class of efficient algorithms that can be sped up near arbitrarily by parallelization

Hmm your last sentence seems to exactly agree that it's a class of algos that parallelize well? What does sped up arbitrarily mean? It's still polynomial speed up right?

It's a difference of degree. People expect something that "parallelizes well" to show near 1-to-1 speedup. Double the hardware, double the speed. This is "you can always speed it up, but the hardware requirements can increase at any polynomial rate".

Ah got it. Reread previous comment and that makes sense.

Yeah it's more of "on a hypothetical infinitely parallel computer, you'll get a big speedup'.

Which is still useful if you can prove a problem is in NC. It's just not quite as strong as people make it out to be.

if supplements don't absorb and therefore don't affect health, there's no reason to take them.

You missed the K2 part of his comment though. Both my mother and I have chronically tested incredibly low for vitmain D, both always taken supplements, both never had improvement. A couple years ago, my mom texted me saying she tried a D3+K2 supplement and for the first time in her life tested in range for vitamin D on her panel. I was skeptical but tried it, and have tested in normal range since.

Arguably it's a CFAA violation, but that's not a law that will ever be used against a company.

Add/Sub isn't 1 cycle if you want overflow handling. One of the really nice parts about float is that it loses precision gradually.

What do you mean by Array Language? Would Julia qualify here?

I was thinking like APL, all the open ones are float64 based.

on a Mac you should be able to emulate it pretty quickly since it's arm to arm

Last anyone tried that in earnest, the binary executable formats were of course incompatible and there were hardware checks.

the problem is Tesla's board is controlled by musk

The mitigation here is to make it only turn on after 60 days. most places don't store cctv footage for more than a month, so if you have a dummy period, by the time it's noticed, the footage will be gone

Good point

the other part is that numbers and symbols were very much not the priority. The printing press was for books, magazines etc. math remained hand written until the computer

Nope, not at all. Monotype had a special system for doing math in hot metal typesetting. With handset type it was possible, but very time-consuming. You can find typeset mathematics going back centuries before the computer. There were also (somewhat impractical) systems for setting music with metal type although engraving was more common because of the interactions of lines and symbols.
