If you read the last sentence of the post that you're replying to, I already said that it won't matter to most people. That being said, "is only for editing in post" (which is not really true, banding is an issue in scen

I'm guessing you don't record videos then. In terms of video capabilities, Canon 5D Mk II is limited to 8-bit 4:2:0 1080p H.264 recording at 30fps, maxing out at 12 minutes of recording. That is a far cry from 10-bit (or 12-bit) 4

If you look at the plots in the 2nd link you are referring to, they show the gains of AVIF over WebP are also similar, so the case of AVIF "isn't a sufficient incremental benefit" as well by your criteria. Not to mention JPEG

Physicist here. Why is this crackpot paper on the front page of HN? (I'm guessing posted by the crackpot author himself) No, you can't reconstruct physics from those 9 half-wrong statements that were pull out of thin air: entropy

You can call in convention as many times as you want, but unfortunately, it just is not a convention. It is called theory of electrodynamics which is a well established, experimentally verified branch of physics. What exactly is more su

What is not true? You can't have reference frame independent (which is a term that also includes orientations) Maxwell equations and anisotropic speed of light at the same time. If Maxwell equations are correct (which was already well

Physicist here. It's not an axiom, historically, it follows from Michelson-Morley experiments, which precede special relativity, and whose purpose was to detect such an isotropy. They repeated the experiment during different times of t

You are not answering the (rhetorical) question that you quoted, and the answer to your response is already in the paragraph that followed it: As I said, the necessary keywords for Googling it, along with a brief description is already pres

So you think there's a cabal of "gatekeeper" scientists who are trying to hold the hordes of capable (yet somehow unfamiliar with the corresponding mathematical literature) engineers from making useful contributions to their

You are saying most people don't know what η in that context means (=people who likely haven't read a book or a paper on stochastic gradient, and don't know how it actually works), but they would somehow magically figure out

by tagrun 4y ago
Unlike the example in the link you give, η isn't a generic random name like a,x that can mean anything. If you ever read a paper on stochastic gradient optimization, you'd know that η means learning rate in the context. It is bik

Sandboxing without any overhead is pretty accessible on any Linux distro, so I don't see why QubesOS should be the go-to choice. For example, I use firejail for all internet facing applications that I use (also for Wine and any proprie

You can have matrices of anything including rings, quaternions, octonions, dual numbers, matrices, vectors, bras, kets, etc etc, as long as you can multiply and add those objects. If you prefer real numbers, use the corresponding wavelength

My favorite colors are 1, 2, 3 and 4 in some 8-bit grayscale color space. Here's a matrix [ 1 2 ] [ 3 4 ] This represents some linear transformation, and is a matrix. Are you trying to argue otherwise? FYI, matrices transf

Any 2D array of data is a valid matrix. But not any multidimensional data is a valid tensor.

Which mathematician disagrees with what exactly? Tensors are introduced by physicists to ensure various physical quantities (which involve coordinates and their derivatives) do not depend on the arbitrarily chosen coordinate system. This i

It has nothing to do with tensor fields, uniform/constant tensors still obey the proper coordinate transformations, that's the defining property of any tensor. (With non-uniform tensor fields, covariant derivatives also pick up a

Gtk isn't tied to C++ or Java in any way. While Qt and wxWidgets are written in C++, they aren't heavily tied to C++ either. For all these toolkits, bindings for many languages exist.
