CPUs are 100% efficient if they’re also replacing your electric space heater

I would say that patriotism in small amounts can be beneficial as it can drive you to improve your country, but patriotism in too large of amounts would drive you to ignore its flaws

aa i didn’t see that lol

actually Cunningham’s Law

I am told that where my italian great grandmother lived it was fairly normal to keep a goat in the house (like, indoors) for financial reasons

interesting to me as I have never heard of that being a thing in the U.S.

honestly if you can 3d print something you can make something almost as strong out of wood, it just takes more effort

one could also easily make a disposable mold for a low-melting-point metal alloy, those are much stronger than 3d prints and many can be melted on a normal stove

I think the problem is more that information on how to make guns is now easily available, rather than the specific usefulness of 3d printing as a manufacturing technique

there’s also the ‘being rich’ thing

I wonder if this is partially a north/south italy divide thing (I don’t know all that much about Italy but I have heard the north was generally more privileged)

yea, its because the Italians (and Irish, Chinese, etc as well) generally came to America later and were poorer than the British/French/Germans etc were, so they were often discriminated against (plus the mafia thing, but that also generally comes from being poorer)

my mother is Italian and often gets mistaken for Latin American

a court case also draws out media coverage, possibly more than an extended search would

antialiasing and denoising through temporal reprojection (using data from multiple frames)

it works pretty well imo but makes things slightly blurry when the camera moves, it really depends on the person how much it bothers you

its in a lot of games because their reflections/shadows/ambient occlusion/hair rendering etc needs it, its generally cheaper than MSAA (taking multiple samples on the edges of objects), it can denoise specular reflections, and it works much more consistently than SMAA or FXAA

modern upscalers (DLSS, FSR, XeSS) basically are a more advanced form of taa, intended for upscaling, and use the ai cores built into modern gpus. They have all of the advantages (denoising, antialiasing) of taa, but also generally show blurriness in motion.

“the garbage trend is to produce a noisy technique and then trying to “fix” it with TAA. it’s not a TAA problem, it’s a noisy garbage technique problem…if you remove TAA from from a ghosty renderer, you have no alternative of what to replace it with, because the image will be so noisy that no single-shot denoiser can handle it anyway. so fundamentally it’s a problem with the renderer that produced the noisy image in the first place, not a problem with TAA that denoised it temporally”

(this was Alexander Sannikov (a Path of Exile graphics dev) in an argument/discussion with Threat Interactive on the Radiance Cascades discord server, if anyone’s interested)

Anyways, it’s really easier said than done to “just have a less noisy technique”. Most of the time, it comes down to this choice: would you like worse, blobbier lighting and shadows, or would you like a little bit of blurriness when you’re moving? Screen resolution keeps getting higher, and temporal techniques such as DLSS keep getting more popular, so I think you’ll find that more and more people are going to go with the TAA option.

I think modern graphics cards are programmable enough that getting the gamma correction right is on the devs now. Which is why its commonly wrong (not in video games and engines, they mostly know what they’re doing). Windows image viewer, imageglass, firefox, and even blender do the color blending in images without gamma correction (For its actual rendering, Blender does things properly in the XYZ color space, its just the image sampling that’s different, and only in Cycles). It’s basically the standard, even though it leads to these weird zooming effects on pixel-perfect images as well as color darkening and weird hue shifts, while being imperceptibly different in all other cases.

If you want to test a program yourself, use this image:

Try zooming in and out. Even if the image is scaled, the left side should look the same as the bottom of the right side, not the top. It should also look roughly like the same color regardless of its scale (excluding some moire patterns).

founding fathers?

I don’t really understand how USB stuff works (what is the difference between a hub, interface, and controller?) but from what I’ve seen I think a hub supporting 20gbps would probably be in the 5-15$ range and probably not larger than a few centimeters

If you have multiple ports driven off the same internal hub, they will share bandwidth.

I’m usually happy with increased efficiency as it represents an increase in performance in the future. Cost is something that seems much more inevitable to go down than performance is to go up, so the two metrics I look for in the state of the CPU market are peak single core performance and performance per watt. Of course, this only applies to observing the industry from outside, I’m sure if I was actually in the market for a new CPU right now I’d probably be happier with a worse performance per watt chip as long as it was cheaper.
