My browser has no idea how to interact with a proper HATEOAS conforming REST API, I would be doing that, the browser would just show me responses. And if one claims that this is all that is necessary, because the API response already contai

Seriously, has anyone ever made a non-toy implementation conforming to the idea of HATEOAS? A REST client needs little to no prior knowledge about how to interact with an application or server beyond a generic understanding of hypermedia.

The raven paradox is not that mysterious in my opinion, observing non-black non-ravens is indeed support for all ravens being black. How do you check that all ravens are black? From the set of all objects in the universe you select all obje

Of course under the assumption that LK-99 is indeed not what has been claimed, I am not completely ruling out that they just failed to reproduce the material. And while I initially said that the LK-99 paper does at least not look like a cra

Maybe not yet the final nail in the coffin but I would no longer bet much on a successful replication. Which leaves me wondering how we got the initial papers. Does fraud make any sense, how could you possibly benefit from something like th

I just assumed the uranium one is a joke created after this story started by some third party and made to look like the original one, so I also did not look any deeper. But the channel being created in 2012 then makes no sense. Someone just

I intentionally picked the favorable numbers as I was expecting even with those it would turn out to be a pretty futile endeavor, even ignoring things like forest fires. And it pretty much is, at least with a billion trees. And for a trilli

A trillion trees by 2030, each fixating 30 kg of CO₂ per year [1], with a global CO₂ emission of about 40 trillion kg by 2030 - roughly linearly extrapolated from [2] - that would capture about 75 % of global emissions, much more than I wou

As I learned from the Dave's EEVBlog video [1], their demonstration video [2] says in the description that the material was deposited onto a copper plate which could probably explain the interaction with the magnet. And as I just noti

Just two degrees off? Can they not wiggle the antenna a bit around [1] just as in the old days when you had to hold the TV antenna a bit above the TV to see anything but noise? [1] Joking aside, they obviously can not, Voyager is missing th

The number is wrong to begin with, Voyager 2 is about 20 billion kilometers from Earth [1] if I did not do the conversion incorrectly as NASA shows it in miles only. [1] https://voyager.jpl.nasa.gov/mission/status/

Which falls into the category where I said it would be possible - you don't have to bring your own Hadron collider but only your brain in order to check whether the proof is correct. Admittedly not any brain will do, so in a sense you

Only as long as the experiments are reasonably simple. There are probably still some things requiring only simple experiments to be discovered, but most of the low hanging fruit has probably already been consumed by a couple of centuries of

Okay, yes, there is a bit more information than in a matrix with half the number of entries, namely the position of the zeros. But when it comes to the number of floating point operations, doubling that number seems at least somewhat questi

Does sparse mean anything other than we can not actually do as many FP8 operations per second as we just claimed? To me it sounds like they can do X matrix operations per second on sparse matrices using Y FP8 operations per second, but inst

If you read some real papers and some crackpot papers, you can learn to identify bad papers without having to have much knowledge on the topic. Bad papers will, for example, often lay out trivial things at length, i.e. have very low informa

I got this wrong, they also produced a thin film in addition to bulk material. And my worry was that one could maybe not easily scale this up in case the effect relied on it being a thin film in which case you can only make ever so wide bef

After skimming the paper, it reads like a legitimate paper even though I have zero expertise in the area. That it is in Word instead of LaTeX makes it feel a bit less legitimate to me and they could of course always have some error in there

You mean how can I do any kind of reasoning if I think the logic I use for reasoning does work or at the very least is kind of an arbitrary choice? I have no answer for that. And that is very similar to something else that always bothered m

Math and logic are fundamentally some kind of game, you make up some rules and axioms and then you figure out the consequences. So the interesting question is which rules and axioms you pick and I would guess aliens in our universe would pi

If mathematics (or the underlying 'thing' that math describes) is objectively true or real, then it could have a platonic existence by power of its own self reference. My response would be, that math is not true. It is build on

Sure, they can be and are often longer, but not because you were forced to use long keys, it just happened that the thing you want to store in a hash table is a long string. The way you worded it made it sound to me like you were saying tha

You cannot put 51 pigeons in 50 pigeonholes. So the key length of your hash keys is m >= logn, which means the time to compare keys is also logn, which means hash tables are never actually O(1) access or insert time. I am not sure I am
