Maybe we are just quibbling over semantics but the compiler intrinsic here is '__builtin_popcount'. 'stdc_count_ones' is a standard library element that presumably will be implemen…

I think you shared the wrong link. Based on a quick youtube search I think you meant this one https://youtu.be/EL7Au1tzNxE

For pytorch the analogue is Named Tensors, but it's a provisional feature and not supported everywhere. https://docs.pytorch.org/docs/stable/named_tensor.html

That seems uncharitable. I for one enjoy the tidbits he posts in is blog.

Well, actually... the "main" function is handled specially in the standard. It is the only one where the return type is not void and you don't need to explicitly return from it - i…

Those points are true of current AI models, but how sure are you they will remain true as technology evolves? Maybe you believe that they will always stay true, that there's some i…

I can't understand how you reach your conclusion. At present, if you have financial capital and need intellectual capital you need to find people willing to work for you and pay th…

Actually `e^(sqrt(n) pi)` is very close to being an integer for a couple of different `n`s, including 67 and 163. For 163 it's much closer to an integer, but for 67 you get somethi…

Charitably it was a joke, as was my quip about `e^(sqrt(67) pi)`. It is a funnier joke without a disclaimer at the end, but unlike GP I couldn't bring myself to leave one out and p…

Very nice, didn't know about that one! In a similar vein, Ramanujan famously proved that e^(sqrt(67) pi) is an integer. And obviously exp(i pi) is an integer as well, but that's le…

Right, it's a limit at infinity

You make a valid point, but I feel there is something in the direction the article is gesturing at... The mean of the n-dimensional gaussian is an element of R^n, an unbounded spac…

Ditto. I think that ship has sailed, but I think it's unfortunate that "ReLU(x)" became a popular notation for "max(0,x)". And using the name "rectified linear unit" for basically …

To me it sounded like part of the problem is that people on ECMO cannot leave the ICU because at any moment they might have a complication that requires immediate emergency care. S…

Is github copilot using GPT-4 or 3.5? I've tried to find out for sure but I can't seem to find the information anywhere

I think matplotlib's main strength is its breadth and power. It really lets you do exactly what you want if you spend enough time fiddling and digging through the documentation. Al…

I agree that to fully specify electromagnetism you also need to include how the fields affect charged matter. So EM = Maxwell's equations + Lorentz force equation (not sure why you…

It's true that you can always define notation to combine all equations you want into one. This means that, by itself, the observation that you can write Maxwell's equations as a si…

Sorry, but gauge transformations do not (by construction) affect the physical fields at all. You cannot set E to 0, even at a point, with a gauge transformation.

>You can make the electric field disappear by choosing the right gauge. Same goes for the magnetic field (can't make both disappear together though). What? No you can't. The fields…
