Is that what it takes to get two different desktop orientations using Linux?

I couldn’t resist

You could use Windows 11 from Microsoft, it can do both landscape and portrait.

Ravens make this gurgling throw up noise which is pretty cool

I get the concern that small landlords will sell to big corpos who can handle the thinner margin, but for those smaller landlords that have paid off their property, or bought 10+ years ago, the margins are already super high, so the 3% cap isn’t going to cause them to sell when they have a $1200 mortgage and are collecting $2800 in rent, or no mortgage at all in many cases so pure profit more or less

Because it feels good to shout fuck Donald trump once in a while.

If you don’t like it then go somewhere else.

If I wanted to polarize, I would be on truth social shouting fuck trump, not on Lemmy.

It’s the billionaires that shape the world, not you and me.

The world you would rather live in is not the world you actually live in.

If you get upset when you read naughty words or read an opinion you don’t agree with, then grow up and go fuck yourself.

I can say whatever the fuck I want to say and your opinion doesn’t mean shit to me.

Trump is a piece of shit and I will be glad when he is gone.

Copy paste top answer from the original question is below.

I find it refreshing that there are actually people out there who are smart and understand this stuff, when I am constantly surrounded by stupid people like myself.

For an exact calculation we need to address a few choices: (you can change them, the answer will not be tremendously affected)

1. What is the receiver? Let's assume a 70 m dish, like this one [CDSCC] in the Deep Space Network.
2. [Voyager 1] can transmit at 2.3GHz or 8.4GHz. Let's assume 8.4GHz, for better beam forming (but probably it can only use the lowest frequency at the highest power, so this could be too optimistic).
3. Does "received" mean all photons hitting the antenna dish, or only those entering the electronic circuit of the first LNA? A similar question can be asked for the transmitter in the space craft. We'll ignore this here since losses related to illuminators or Cassegrain construction will not even be one order of magnitude, insignificant compared with the rest. Answers:\

A) Voyager sends 160 bits/second with 23W. Using 8.3GHz this is 4⋅1024 photons per second, or 2.6⋅1022 per bit, because for frequency f the energy per photon is only Eϕ=ℏω=2πℏf=5.5⋅10−24J  or  5.5 yJ (yoctojoule).

B) The beam forming by Voyager's d=3.7mdish will direct them predominantly to Earth, with (πd/λ)2 antenna gain, but still, at the current distance of R=23.5 billion kilometers, this only results in 3.4⋅10−22 Watt per square meter reaching Earth, so a receiver with a D=70m dish will collect only 1.3 attowatt (1.3⋅10−18W), summarized by: Preceived=Ptransmit (πdλ)2 14πR2 πD24 Dividing by Eϕ we see that this power then still corresponds to c. 240000 photons per second, or 1500 photons per bit. If we assume f=2.3GHz this becomes 415 photons per bit. And if we introduce some realistic losses here and there perhaps only half of that.

C) (Although not asked in the question) how many photons per bit are needed? The [Shannon limit] C=Blog2(1+SN), relates bandwidth B, and S/N ratio to maximum channel capacity. It follows that with only thermal noise N=kTnoiseB, the required energy per bit is: Ebit=SC=kTnoise 2C/B−1C/B ⇒ limC≪B  Ebit=kTnoiselog2, where C≪B is the so-called "ultimate" Shannon limit. With only the CMB (Tnoise=3K)we would then need 41yJ, or 41⋅10−24J, per bit. That's only 7.5 photons at 8.3GHz. But additional atmospheric noise and circuit noise, even with a good cryogenic receiver, could easily raise Tnoise to about 10K and then we need 25photons per bit at 8.3GHz, and even 91 at 2.3GHz. So clearly there is not much margin.

Wake me up when this piece of shit is dead or in prison.

I had a job that bought me one of these about 15 years ago, never used it

Modern American liberalism is democratic socialism and that’s what it has meant since FDR…

"In the United States, liberalism is associated with the welfare-state policies of the New Deal programme of the Democratic administration of Pres. Franklin D. Roosevelt, whereas in Europe it is more commonly associated with a commitment to limited governmentand laissez-faire economic policies."Consequently, the ideas of individualism and laissez-faire economics previously associated with classical liberalism are key components of modern American conservatism and movement conservatism, and became the basis for the emerging school of modern American libertarian thought.

This doesn’t mean that liberalism = conservatism.

This is a really insightful argument you have proposed. am going to have to give it a lot of thought because it’s so sophisticated and well thought out/communicated. You should be proud of yourself.

That study, which is admittedly a bit above my pay grade, says that more study is needed. It doesn’t say that diabetes has been cured, which is the headline that media outlets have chosen.

My only point was that if diabetes was actually cured, everyone would know about it, not just you and me.

Maybe you should try putting a stick in your ass

Careful, your ad hominem is showing

How would reading Cell Discovery increase my chances of hearing about a cure to one of the world’s most pervasive afflictions on some obscure Lemmy post, and more puzzling, how would reading Cell Discovery make it more likely that some wild medical claim with far reaching implications would both be true and also absent from every other news source? What kind of magic does this Cell Discovery have?

You just said that liberals are hardcore capitalists despite the fact that liberals are the ones pushing for a hybrid socialist democracy where key industries are socialized so that rampant corruption, which is an effect of the invisible hand, can be avoided. You go on to say that liberal means conservative.

Phrases like ‘we are living in a post truth world’ are a self fulfilling prophecy for those who use that phrase… for the rest of us you just sound like a far-right provocateur.

It appears you are either very confused or you are a dishonest interlocutor and are completely full of shit.

Sad

It’s not autism, it’s the word ‘real’ that threw me off. But I don’t know that suspension of disbelief is any better.

Belief is irrelevant, all that matters is what can be tested and demonstrated.

Also I didn’t realize that shower thoughts required metaphors.

I suppose shower thoughts are generally just half baked ideas, and science is magic is quite half baked, so I think we are good.
