You don't need the look up table. All you are asked for is min/mean/max which can all be computed in one pass without storing the data. All you need is a hash table with 400 entries and 3 floats (running min, mean and max) an

I think what you need is something that is at least as large as the largest Fibonaci number you are going to compute. Since the Fibonnaci numbers grow as `phi^n` where `phi` is the golden ratio (~= 1.618) if you want to use something of the

Very nice! Had never seen this trick. One non-obvious aspect is that the function relies on using Python's big ints, even for pretty small values of n. You are calculating `2^(n(n+1))` for the numerator, so if n=8 you already get `2^72

I believe numpy introduced ndarrays with user-specified strides, that made this a O(1) operation. Even if not, it certainly predates pytorch in this regard. Pytorch (and other tensor libraries) just used the ndarray concept from numpy.

The analysis in the article is mostly very good, but I object to this observation `The biggest loss of all, though, is a necessary one: the myth that anything but a for-profit corporation is the right way to organize a company.` I don'

If we had to have global policing of every large computing cluster and everything that runs there, that does not feel to me like a huge overreach or something that could easily slide into totalitarianism. It would be better if we didn'

Well, it's a matter of opinion which one is the root cause. My take is that if you remove nuclear/biological war out of the picture somehow, climate change is not an existential risk. If you remove the latter then the former is st

I don't disagree with that, but then the risk is nuclear war. It could be triggered by global warming conflicts or by something else. Still, like I said somewhere else, even all out nuclear war is unlikely to lead to human extinction

Oh, for sure. I am just saying it's not an extinction risk, not that it is not a huge and pressing problem. I would still bet against going back to 19th century. Worst case scenario for me is hundreds of millions dying and a big regres

I am not saying it's not a huge problem. Hundreds of millions dying would probably make it the worst thing that ever happened. I am just saying it's not an extinction risk.

Interesting, I have some vague recollections off hearing about this. But according to your link, IPCC says it's not a plausible scenario in the medium term. And I'd say that even 8 degrees of warming wouldn't be enough for ex

For sure. If the Russian federation breaks up into a bunch of independent states we will have a huge problem. It was not very fair from civil war already, with the aborted coup. Could you imagine if the Wagner group became a nuclear power??

Sorry, I meant IPCC (International Panel on Climate Change). I don't think IUPAC (International Union of Pure and Applied Chemistry) has come out with views on impact of global warming :)

You are right, but "human civilization will be extinct" is an awkward phrase. Human extinction via climate change is off the table. The end of human civilization? Depends on what one means by it. If it means we'll go back to

For frontier AI models you don't need a few GPUs or a small cluster. You need thousands of them, you need them all connected with high bandwidth and you need a lot of power. It's not something you can do in your garage or undetect

It will be very difficult, but if you think about nuclear weapons it doesn't sound so hopeless. First nuclear weapons were used in 1945, almost 80 years ago. Today, out of ~ 200 countries in the world only 9 have nukes. Of those, only

There is no scenario where climate change leads to human extinction. Worst case scenario is global population goes down by a single digit percentage. Horrible, horrible stuff, but not extinction. And most likely scenarios are not nearly tha

If you look at the link to the Cloudfare post [1], they are comparing a bunch of different IPC methods. I bet what I did is for all the other ones (shared memory, mmaped files, unix sockets, etc) they did send 1KB messages, but for signals

That is a valid point but I think that is outside the scope of dimensional analysis. Distinguishing scalars from vectors (or just different rank tensors in general) is usually obvious, because they have a different number of components, and

Very interesting. And it's not even an esolang, but something actually intended for production use! Looking closer, it's not as bad as what I had in mind. Association order only depends on type, not value (which is what I meant by

Wow, this is (evil) genius. It suggests all sorts of obnoxious "features" for esolangs: - Order of operations depends on number of terms in more complicated manner. - Order of operations depends on data? This would make compiling
