Yes, 1 just looks like the bare minimum stamped sheet metal

In my computer once I installed my graphics card the integrated gpu was disabled, but there was a BIOS setting to keep both enabled

I was thinking about this a bit yesterday and I think the most feasible way would be to suspend a glass sheet above the lake, and then give people harnesses with magnets on the top that attach to magnets on the other side of the glass sheet. Then just put ball bearings on both sides to reduce friction.
- Comment on Horror 5 weeks ago:
You could try to use magnetism or something tho, although that means you’d only be able to walk on specially prepared lakes

Unless there’s force coming from somewhere other than buoyancy, you can’t get better than than 1.29 kg per cubic meter of lift in air at stp.
- Comment on Horror 5 weeks ago:
Well, air weighs a little bit more than 1 kilogram per cubic meter, and those balloons look a little bit smaller than a cubic meter
- Comment on Horror 5 weeks ago:
The theoretical best lift from a balloon that size is about 1 kg I would estimate
- Comment on Horror 5 weeks ago:
Well, if we used a pure vacuum, you’d only get about 17% more efficiency than just using helium I think
I don’t know if they had helium when this was made tho, they might have been thinking more hot-air-balloon style
- Comment on Horror 5 weeks ago:
Any amount of water contact introduces a fair amount of drag. There may be an ideal point somewhere in the middle, but I think if you take this to it’s natural conclusion you get a zeppelin.
I did a little bit of math and I think that to lift the payload capacity (including fuel and crew) of a modern day Panama canal ship you would need about a tenth of the peak U.S. helium reserve (a cube about half a kilometer long on each edge, about 1.3x longer than the long dimension of the ship)
I don’t think you’d get the best fuel efficiency going upwind lol
Anything smaller would come with proportionally less downsides and at least proportionally less benefits. I doubt it could ever be a net positive in any useful metric.

Degrees of freedom
3dof things usually just track rotation, because that’s easier. But for a full VR experience, better depth perception, and more normal interactions, 6fof is used which tracks position as well.
- Comment on Half Life: Alyx is Five Years Old Today 1 month ago:
IMO even a normal flatscreen is more immersive on average than a google cardboard, although that’s partially because a flatscreen hides the flaws in the graphics a lot better.
HLA tho needs 6dof controllers for the intended experience. That mod tries to get around it, but that obviously involves some sacrifices.
- Comment on Half Life: Alyx is Five Years Old Today 1 month ago:
IIRC no cardboard ‘headset’ ever had 6dof tracking. It’s about as far as you can get from an immersive VR experience. I say this as someone who bought one before learning about VR and getting a real vr headset.
It’s like VR with all of the downsides, even less apps, and the only advantage over a flatscreen being (limited) depth perception.
- Comment on Half Life: Alyx is Five Years Old Today 1 month ago:
I think there’s a mod for that iirc

Oh I guess I set it to private instead of unlisted on accident. It should be fixed now.

I mean just from persistence of vision you’ll see multiple copies of a moving object if your eyes aren’t moving. I have realized tho that in the main racing game I use motion blur in (beamng) I’m not actually reaching above 80fps very often.
here, I copied someone’s shader to make a quick comparison:
with blur: https://www.shadertoy.com/view/wcjSzV
without blur: https://www.shadertoy.com/view/wf2XRV
Even at 144hz, one looks smooth while the other has sharp edges along the path.
Keep in mind that this technically only works if your eye doesn’t follow any of the circles, as that would require a different motion blur computation. That’s obviously not something that can be accounted for on a flatscreen, maybe in VR at some point though if we ever get to that level of sophistication. VR motion blur without taking eye movement into account is obviously terrible and makes everyone sick.
Someone else made a comparison for that, where you’re supposed to follow the red dot with your eye. (keep in mind that this demo uses motion blur lengths longer than a frame, which you would not have if aiming for a human eye-like realistic look)

My mom is a biologist and complains how physicists always come into biology, try to reinvent everything without looking at any prior work, and then fail to execute their (sometimes interesting, sometimes not) method

I would honestly be very surprised if any Republican politicians actually care about sex or gender. I think they’re just evil and those are convenient issues to divide the working class. When you don’t have popular policy in real issues, you need to make up some fake ones to get people to still support you.
- Comment on Anon fixes their games 1 month ago:
You still see doubled images instead of a smooth blur in your peripheral vision I think when you’re focused on the car for example in a racing game.
- Comment on Anon fixes their games 1 month ago:
It’s usually better in modern games. In the 2005-2015 era it was often extremely overdone, actually often reducing the perceived dynamic range instead of increasing it IMO.

I think Halo Infinite has a good example of a limited ray traced effect (the shadows) and an example of a terrible DoF effect (it does not look realistic at all or visually appealing)
- Comment on Anon fixes their games 1 month ago:
Personally I use motion blur in every racing game I can but nothing else. It helps with the sense of speed and smoothness.

I bought Trackmania United Forever last weekend and it’s kinda interesting because the stadium environment still looks great, most of the rest look ok and some others look pretty bad.

Oh probably

Yeah, but it does have 10^67 years to catch it.
Assuming the light isn’t bending at all, I think it should get about 890 watts of light, or 2.810^10 joules per year (or 3.110^-7 kg per year?) from the sun, which should be enough to cause it to grow, at least while the sun is still around. I expect it would get a lot more mass from gasses, meteors, and dust in that time frame. Based on your numbers above I think it should only be losing like 2^-40 kg per year if it was losing mass at a constant rate.

Does the energy of light entering the black hole make it last longer?
- Comment on That explains a lot 2 months ago:
The black hole with the mass of the earth would have a diameter of around 4 cm

Or, the Italian way: simmer garlic in a pan with olive oil, throw in the vegetables and a bit of water, throw in some salt, cover, cook until soft, check occasionally that it isn’t burning
