I read it as tupple.

-1 for Hertz is listed as "earth rotation cycle, tide changes, circadian rhythm", but 1e-1 hz is just a cycle time of 10 seconds. More like how often waves crash on the beach.

Great catch! Super helpful. Thank you

Yes, just prototypes: https://www.uploadvr.com/meta-butterscotch-varifocal-prototy...

It's for wireless PCVR, more useful for standing games like Beat Saber, HL:A, Bonelab, VRChat, etc

It even improves seated VR! You get better image quality using wireless over virtual desktop than wired using quest link.

[ehaliewicz2 → dharmab]

It depends on your network though. In my case the image quality was good, but going to the link cable was a substantial improvement in quality and latency.

On: Google calls Gemma 3 the most powerful AI model you can run on one GPU

[hnuser123456]

I suppose we could eventually get to a super-MoE architecture. Models are limited to 4-16GB in size, but you could have hundreds of models on various topics. Load from storage to RAM and unload as needed. Should be able to load up any 4-16GB model in a few seconds. Maybe as well as a 4GB "Resident LLM" that is always ready to figure out which expert to load.

Because believing the FSM oversees the electrons doesn't help you build new things and demonstrably increase your understanding of the world.

Oxygen detection on specific exoplanets is very difficult, unless the planet happens to pass between its star and Earth so we can see light passing through its atmosphere. Oxygen detection across an entire galaxy, not as hard.

There seems to be a large region of the universe, beyond furthest edges of the observable, but "in front of" the CMB, that is already outside of our past light cone due to expansion of the universe.

[hnuser123456 → hnuser123456]

To add, Earth is only ~4.5 billion years old, the universe is 13.7 and possibly double that, so earth is only 1/3 the age of the universe. It took a lot of big stars going supernova to pollute the galaxy with enough dirt to make rocky planets, and in all that meantime, everything has been flying apart, with a significant chunk of it already so far away and expanding away even faster, there is measurable difference between the observable universe and the "whole universe."

On: How fast the days are getting longer (2023)

[hnuser123456]

Yes, though a location at 45 degrees N/S only gets 70.7% as much sun power per area due to not being perpendicular to the sun's light, and even less on the ground due to extra atmosphere to pass through.

[frankus → hnuser123456]

Appropriately enough, that "everywhere on earth gets the same number of hours of daylight" fact came from a solar system salesperson, who didn't go out of his way to emphasize the atmospheric effects here at ~49°N.

The silver lining is that our longest days are often our sunniest.

[hnuser123456]

I didn't have to do any cleartype tuning on my LG C2. But maybe since it's a TV they have room for conventional subpixel layouts.
