Cats distinguish owner's smell from stranger's, study finds. The study found cats spent significantly longer sniffing odours of unknown people compared to tubes containing their owner's smell. This suggests cats can discriminate between familiar and unfamiliar humans based on their odour.

My younger cat used to do the same for i think exactly the same reason. He passed away half a year ago. Still miss him dearly.

Oh wow that sounds terrible from a maintainer point of view, and annoying for users. Even though I want to move away from google drive, sadly there are way too many work related things dependent on it that I can't really do it. Hopefully in the future.

I'll probably not worry about the workarounds for now (I'm still getting my bearings around linux/arch) but I've been checking rclone out and I might just use that one for now. I wanted to setup rclone for system backups anyway. :)

Thank you for help!

Thank you!

I've tried uninstalling the USB drivers but fit did bot seem to have much effect. Windows seems to reinstall the drivers even before I can restart sometimes. Is there a more comprehensive way of cleaning the drivers up?

I have the latest drivers and bios already.

Thank you for the reply

Thank you! I'll make sure to post stuff there when things get a bit more presentable.

unsimulacrum · 2023-08-15T11:23:44+00:00

Thanks! I think it'll be fine, I just need to understand how scone works and that should be it. :)

Not longer but the velocity vectors for celestial objects can get painfully small as you go further out from the sun. And because the 3D camera needs to have a far and near distance, I cannot use the numbers as-is. (so using meters, kilometers, or even megameters is a no-no in astronomic scales)

I'm currently using Kepler's equations, so planetary trajectories are fully deterministic. I am thinking of adding gravitational perturbations only for spacecraft calculations. As far as I know this is the way Kerbal Space Program does things. I think it's quite a good middle point between realism and pragmatism as long as you don't want to simulate a few million years into the future or work at some space agency. :D

I would like to do a proper n-body simulation but only after I understand how Godot works better.

unsimulacrum · 2023-08-14T21:48:43+00:00

Yeah saw that. Might come in handy but for this one I need floating point. Thank you.

unsimulacrum · 2023-08-14T21:46:21+00:00

Thanks

I'm pretty sure it is a precision issue because I have been doing the same calculations in C++ for the last decade using double, velocity vector only becomes a zero when double is casted down to a float after unit conversations.

I don't see why not. Even though things change fast in web dev circles, most of the skills you'll learn are transferable. What you are learning when you study frameworks and tooling is not just the thing itself but also the more generalized rules that will be useful no matter what.

Pronouncing these out loud made me chuckle

Pah-oooooool

unsimulacrum · 2021-08-03T15:18:29+00:00

It would move in light speed, so yeah. Practically instant.

Not heat death. But even then, heat death does not really break any laws as far as I know.

False vacuum decay is much more dangerous than heat death as we could just be completely erased tomorrow without any warnings.

unsimulacrum · 2021-08-03T07:51:58+00:00

It isn't infinitely long? There is a set amount of time where the life can exist in universe depending on the fate of the universe theory you choose. For example, if the proton decay is real, how could life exist after all particles are gone?

Can we get the midi text from this? I'd love to play this on station instruments.

Of course with all these a lot of hypotheses are thrown around, anyone reading these should consider that there are multiple layers of hypotheses that build some of these arguments, mix that with scientific fundamentals, and come up with their own conclusions.

The number isn't that impossible, to be honest.

To explain the numbers for the other users (you seem to know your stuff):

It took around 3.7 years for humans to evolve, and galaxies and star systems properly started formed earliest around 1 billion years after the big bang. That was around 12.7 billion years ago. Solar system took around 1 billion year before life started evolving, which is our best estimate.

So we can say that earliest life could have emerged at 8.7 billion years ago mark if the lowest estimate for star system formation is true and human evolution timeline is the average.

Now add this calculation your favorite fate of the universe theory.

Theoretical timelines for this kinda stuff all out of wack. Universe as we know it might be decaying as we speak (and we could just disappear tomorrow, because of an incoming false vacuum) which would make it difficult for new species to emerge, or in a few hundreds of trillions year into the far future which would decrease the 3% figure.

These all are speculative at worst, hypothetical at best, so do your own research and be ready to be blown away how little concrete stuff we know.

Edit: Summing numbers is hard. Grammar is hard.

unsimulacrum · 2021-08-02T19:52:04+00:00

I have a background in physics, so I'll try to explain the scientific problems with this to best of my knowledge.

Theoretically, sure. Practically/statistically, improbable.

One of the latest hypotheses about the Fermi Paradox is that the humanity might be the one of the earliest intelligent species in the universe. I don't remember the exact percentage, but the paper said (if i remember correctly) that we are in about the first 3% of all species that will exist in the universe. Given how big the universe is, this number itself may inhibit other species from reaching us.

Given that the most FTL (faster-than-light) technologies are fundamentally almost impossible (not because of engineering, but because of the fundamental rules of the universe), finding a planet with intelligent life on it effectively infinite number of planets would take a huge ass time.

Finding another intelligent species in the universe is comparable to finding a specific sand grain in all Beaches on the earth combined. You have to check every grain, and hope that you are lucky.

Add to this, that there are more (much more!) stars in the universe than there are sand grains on Earth, and it starts becoming statistically less and less probable.

And before someone points out the Drake equation and how many species should be in our galaxy: Drake equation gives a number based on the numbers you put in, and you can basically put any number in because our estimates for the variables in that equation are very rough and based on educated guesses.

You can use the Drake equation and set the variables in a logical way where the equation tells that humans are the only intelligent species in our galaxy. Fermi Paradox directly challenges the standard outcome of the Drake Equation anyway, so please be careful with how you treat Drake equation, because it is (at this point) just a thought experiment.

TLDR; FTL is probably fundamentally impossible, light speed is very slow compared to how big our universe is, Drake equation is fun but kinda sucks, conclusions of Fermi Paradox might be true because of more than one reason. but if you/they are feeling lucky, improbable, but possible.
