No. This proof says nothing about the security of RSA. I don't know anyone seriously trying to break RSA by factoring polynomials. It's pretty easy to test a bunch of random polynomials and pretty quickly find that this just isn&#

It turns out there are some longer videos on YouTube, though also curiously cut down sufficiently far that a lot of it is without context, e.g. https://www.youtube.com/watch?v=PkSzmnA1CQQ https://www.youtube.com&

There is an article claiming that an AI held its own against a human in a debate. But the supplied video gives just a few seconds of canned material which could apply to any debate. Am I missing a video somewhere? Even on their website they

When this topic is discussed using common speech, it becomes confusing. `Consciousness' is used to describe so many things: the state of being conscious (as opposed to unconscious), the feeling of awareness (as opposed to an automaton

I would be more inclined to believe it if it didn't fly out of frame before it had even been in the air as long as the "unsustained" flight. I simply can't imagine why they are so careful to obscure their sustained fligh

You move around by dragging the picture from side to side. Not the most intuitive interface, to be sure.

Like other colorisers I've seen, it does seem to have non-uniform colouring of clothing, with bleed from surrounding areas into clothing being fairly common. That's seems slightly weird, as I am sure few training images would have

He/she does go on to explain what they mean by that: press releases deliberately talk up the `magical' aspect of quantum computing, and this is at least in part necessary for further funding. You can argue about whether the word `

Physcial qubits currently suffer from noise problems and so logical qubits have to be simulated. You can't just implement them directly in a scalable way in hardware. So, you could say that a meaningful, scalable quantum computer of an

There are many applications of a fast factoring algorithm in number theory, and many people who would love to get their hands on one for that reason. You'd be exceptionally famous if you developed a very fast algorithm for this. That i

I'm not sure that becoming a founder at 45 is likely to be successful. It is surely because successful founders have many failures under their belt that the average successful founder is 45. This implies that stepping out at 45 is not

It's not relevant for the size of integers considered for cryptographic applications, and I doubt sheer performance is the main consideration in such applications anyway. Having said that, if you do want a simple BSD licensed library f

When I was younger, my friends had my telephone number. I used to enjoy coming home and chatting to friends on the phone. I loved receiving calls. There was something nice about having that landline handset against my ear. Nowadays, the tax

Is it yet known what the optimal sequence is for 3x3 matrix multiplication (for noncommuting entries, of course)?

There's a degree 10 polynomial here, but it has an integer root, which seems to be what they computed. This can be achieved just by factoring the leading and trailing coefficients, and by various other easy methods. It's not reall

I'm not seeing that. I see a degree 10 equation, which oddly has no rational roots (though my guess is this is what is meant by "solving"). I've never seen any mention of the Chinese solving degree 14 equations in any bo

Looking at the description of the C64 port, it looks like each frame of the character in the DOS and Apple II versions were just drawn over the scene and the pixels affected just redrawn when he moves (including blocks that obscure his view

The DOS version had a CGA port, which runs extremely slow. Seems to be about 5-8 fps on a 4.77MHz machine, probably 8-12 fps on an 8MHz machine. The technical document doesn't seem to say how the sprites were done on the Apple II (I co

It may be a tiny thing, but I'm still amazed at how fast the new REPL starts up, and how quick the package manager is, compared to what was there before. Congrats!

There's no way today's software can be scaled in terms of performance in the face of the "end of Moore's law", with a mere recompile. Today's software will be displaced by tomorrow's software. Of course I

They've hired heavily on the GPU side and announced a partnership with AMD (presumably to use their infinity fabric). This'll sound a bit strange at this point, but I have the feeling CPU's will become little more than an I&#

The problems Intel has at 10nm are well covered by the tech press. And Intel has confirmed this to investors. The thing that is new here is the claim that internal documents show that Intel is rather more worried than people expected. It&#x

I'm still talking about undergraduate mathematics here. There's billions of dollars spent worldwide on providing exactly that. The issue is that a standard undergraduate course, especially in mathematics, is quite deep, relative t

This is probably an obvious statement, but if you write such a reference, then there will be one more reference, and someone else will have to write a new, more comprehensive reference based on all the existing ones, plus the new one you wr

Wikipedia doesn't contain nearly enough knowledge. It tells you what a CPU is, not how to build one. It tells you some of the chemical properties of certain common chemicals, but not the millions of reactions, or thousands of entries i

Getting a CPU Z validation is a sport, nothing more. But they have to develop tricks and techniques to further their sport, which may have other benefits in terms of understanding the hardware.

I am not sure if they got into the OS at that speed. From the video I got the impression that they adjusted the core frequency and voltages using software, once inside the OS.

There'd be something like a 2% error margin in their timings. They can only report what they measure. It's actually a good sign such discrepancies show up in their data; it means it is likely real data.

Whereas a lot of OA options exist, they are quite scattered. Some universities have preprint servers that are more or less maintained, with varying up times. There are multiple open access options you have to pay for, if your grant or insti
