This looks very interesting and impressive, and I hope this will catch Jonathan's eye. Have you though about how the spin of particles could work in this framework? And have you though about what it would look like to extend local gaug

It appears no one here has actually read the essay. He's not talking about mathematical complexity of Maxwell's equations (and no, you can use differential forms, Clifford algebras, quaternions, vector calculus, but no matter how

Are you being thick on purpose? You are lying, you know you are lying, and you keep lying. 1. And you can't ignore the context and the conclusion of the study and cherry pick half sentences. What a convenient "brevity" that i

Yes, you are making a lot of mistakes. No, on the contrary, both studies encourage the use of masks. And it's totally beyond me why you're so bent on distorting the fact and trying to get that dangerous message of discouraging the

I gave two reasons, I'll give them here again: 1. Masks do work. Wearing a mask obviously provides a better protection than nothing for a healthy person. You can also read a few studies https://journals.sagepub.com/doi&

I'm baffled how one office spreading patently false information that defies logic and physics could be so effective. Not using a mask as community will ensure that virtually everywhere is potentially contaminated and you are under a la

No. You clearly have no idea how this works, and are basically an armchair health expert spreading patently false and dangerous information. Health care workers are required to use masks to protect immunocompromised patients. In Japan, peop

This is why that someone also needs to wear a mask. Don't worry, people aren't morons and have been using masks in Japan and other countries for decades just fine. Yes, masks can hold contaminated droplets --that's their purp

Expect he is wrong and spread dangerously false information and pushed people toward danger. And you are also doing it here as well. His "correctness" is reflected in the number of infected people in the US, which is over 27000 no

The real difference lies in the responsible community surrounding you which doesn't behave like nothing happened.

I wouldn't lump them together. There is a chasm between the adoption numbers for H.264 and H.265, HEVC failed gain the momentum AVC did --which is exactly the point GP is making. MPEG-LA is indeed well connected to lobbying parties and

That's a rationalization though, not the reason. FreeBSD's GPL "exorcism" efforts had been going on long before FSF started floating ideas about GPL 3.0.

Why? You don't understand what it is, so we must pick one from your false dichotomy? This dismissive and derogatory attitude of "if it's not Nobel Prize level, it's bullshit" is one of the root problems with regards

The equivalent functionality is the File Browser tab when you open RawTherape. You can filter images, assign ranks/color labels, create queues, do batch edits, assign a dark frame, etc etc. It doesn't have "collections"

RawTherapee does photo management and is non-destructive as well. Darktable supports masks and parametric masks for almost all operations. RawTherapee on the other hand has a wider range of tools and support for profiles and raw formats.

All floating point implementations are deterministic. You do get the same results on each run on a given CPU. There is no stochastic floating point implementation in AMD or Intel. I understand that they don't agree when run on differ

That indicates a numerically unstable code on his/her part though. Scientific results shouldn't depend on unspecified epsilon values that fall within the spec. If they're getting different results on different CPUs which both

This makes no sense at all. The differences that you're seeing fall within the spec. You're basically saying that Intel is justified in crippling AMD CPUs if AMD's floating point instructions doesn't implement Intel&#x27

As you point out, the spec includes threshold values for errors, and the actual epsilon error values vary between vendors as well as within the CPUs from the same vendor. He's wrong, because 1) this discussion is his false claim that I

And how does the difference between IEEE-754 1/x and SSE reciprocal instruction on the same CPU is relevant to Intel disabling AVX/AVX2 on AMD CPUs? So your logic is: given that IEEE-754 1/x and SSE rcpps yield different resu

Then it truly is irrelevant! You're not even talking about CPUs vs CPUs. The differences you are quoting coming from the difference in libraries (sin, exp etc will give different results depending on them libm implementation, that&#x

I completely disagree. Your plot doesn't show CPU instructions are unpredictable (which is not correct). Yes, IEEE floats are not the same as real numbers (which is what your plot is showing): they have inherent precision errors, and f
