Is there any need for that? Just have a few good CPUs there and you’re good to go.

As for how the HW looks like we already know. Look at Strix Halo as an example. We are just getting bigger and bigger integrated GPUs. Most of the flops on that chip is the GPU part.

CDNA is based on the older gcn arch so they share the same as pre RDNA ones and RDNA ones.

I tried it out.

I asked if it can generate a voice clip. It said it can’t on the chat.

I asked it where can it make one. It told me to use Audacity to make one myself. I told it that the advertisement said it could.

Now it said yes it can here is a clip and gave me a broken link.

It’s a hilarious joke.

They were around $60 or your regional equivalent. This means $140+ today assuming 1990 dollar.

And that is why we use products made by companies in California.

Non competes are good for the big incubent companies, but bad for the economy and the workers.

Another issue are non competes.

Everyone wants to get a tech sector like California but insist on having non competition agreements being either valid or conditionally valid meaning there is a gray area that stifles innovation.

Inverse fourier transform of a non transformed signal gives you basically the fourier transform with some changes (I can't remember which, were the numbers conjugates or something?). Applying it the second time gives you same result as if you'd do the forward direction transform twice.

If you apply fourier transform 4 times you get your original function back. You can think of it as 90 degree rotation. Inverse transform just rotates it in the opposite direction.

The rotation analog is not even too far fetched as fractional fourier transform allows you to do an arbitrary angle rotation.

Depends on the place. This sort of interoperability is explicitly allowed in the EU.

It was a joke. Obviously there was no contact whatsoever between the two.

Gemini basically forces the current US ethnical representation fashions to every situation regardless of how well it fits.

It was extra hilarious when asked to generate a picture of ancient Greek philosopher it made it a Native American. Because it is well known Greeks not only had contact with the new world but also had prominent population of Native Americans.

It really wants to mash the whole world to a very specific US centric view of the world, and calls you bad for trying to avoid it.

Not just that. It does require Atkinson cycle to reach the efficiencies they have. It just means that the compression stroke is shorter than the power stroke.

Basically with that cycle they can get massive compression ratios. As an example newer Toyotas are at 14:1 ratio with 41% thermal efficiency. That’s close to diesel territory on a gasoline car.

Naturally when you floor it it goes to Otto cycle and efficiency drops.

It may be choking on too large of a threadcount. By default Starfield creates as many workerthreads as what you have cores. And it scales really badly. For your setup it likely makes 32 threads like it does on my 16 core Zen4.

I limited mine to the same as what the consoles have and it made things quite a bit smoother. You can try adding these to your StarfieldCustom.ini

1) Probability of that is so miniscule as to be nonexistent. I’d suspect foul play at that point. As in someone just transporting the animal there. You can’t really get identical DNA on earth. It’s to be expected that it would be even harder if there are no common ancestors. 2) Yes. In order to make that you need to basically fully understand the organism in question. All of it’s properties are the same and product of the same evolutionary history by the virtue of you just looking at the existing creature and making an 1:1 copy

In 2020 Apple invented unified memory?

More seriously people need to stop with the Apple comparisons. Unified memory has been a thing for a way longer time. Heck around 2014 AMD had integrated GPUs with not just unified memory but fully unified address spaces with the host. Unified memory in itself happened way before that.

Not to mention that mobiles have always been unified archs. It’s just a design decision.

Browser doesn’t really have limitations in that regard. Thus it offers nothing unique in that sense that’s not already in normal windows/whatever desktop platform demos.

If some frontend developer would make a demo without using webgl or webgpu that would actually get interesting.

With browser it’s the bog standard WebGL and now WebGPU. They bring nothing over just doing normal demo using native graphics apis directly.

They are good ways to distribute programs for customers but that’s it.

It’s the same mechanism that triggers the game mode in Windows. You can tag a program in the Xbox game bar as a game if it hasn’t recognized it by default.

Even better: Make the train stop right before lights turn red. With careful timing you can wreck the car with no harm to the train.

On that I fully agree. And the reason why scala approach doesn't work is because it's horrendously inefficient. What actually does work at massive scale is the GPU style workload.

Intel tried with their Larrabee on what happens if they just toss in ton of traditional low performance CPU cores. It failed to perform. It's really hard to beat the modern SIMT style GPUs when it comes to massively parallel computation.
