Absolutely incredible band

That too 😂

The greenhouse effect still has a limit to how much it can trap.

At the end of the day infrared radiation is still basically light.

Even on the cloudiest day, or when there is super dense smoke or ash, it is still not pitch black out. Some light gets through. If you are looking into a mirror, it might seem like it reflects 100% of light. But they only reflect around 95%.

You would require something which can let through 100% of all sunlight, but still trap 99.5% from leaving.

You could have a look at how one-way mirrors work, to understand the percentages of light passed through and reflected.

Data comes from NASA planetary fact sheets (amazing resource btw).

Overall equation structure:

Circular area that can receive sunlight: pi x radius ^ 2

Total incoming power : solar irradiance x circular area

Spherical area : 4 x pi x radius ^ 2

Black body radiation : stefan-boltzmann constant x Area x Temperature ^ 4

You know have incoming power and outgoing power.

Percentage : 100 x (Outgoing - incoming) / outgoing

I don't think so.

Even out at Mars you already have significantly diminished solar incidence.

I think that past Saturn you probably start to have so little incoming solar energy that it's almost impossible to retain it.

EDIT:

Saturn receives around 1% of the solar irradiance of earth.

Pluto receives 0.064%. less than 1W/m2.

With a radius of 1188km, the absolute maximum incident solar energy is 3.8E12 W. (Assuming no efficiency loss as the angle of incidence decreases due to curvature)

The radiating surface is the full sphere, and using Earth's black body temperature of 254K.

Therefore, Pluto would be radiating approximately 5.67E-8 x 254^4 x 4 x pi x 1188000 ^2 = 7.38 E14.

In other words, you would need to retain at least 99.5% of all energy emitted by pluto. Mirrors reflect around 95% of visible light, and infrared is even more difficult to reflect.

For me the main thing would be airflow there, and the type of work. I've done full days in 35+ machining but windows and doors were open so there was a breeze which made it bearable (not pleasant days mind you)

The poor placement of "people having sex with hats on" makes it appear like the x-axis label. Which implies that there are >1900 people.

Interesting article, clearly written with an extreme bias.

It definitely makes some extravagant claims that are not thoroughly backed up.

This definitely doesn't belong in TIL. It is not an established fact, and if it is an established fact, a medium article from a strongly biased author is not a reliable source for it.

TIL the US committed mass war crimes in Korea resulting in a 20% population reduction is maybe more apt. But it still requires a better source than this article. Such as an academic paper or article which includes references to reliable sources.

Yeah my bad, didn't realise he was being held in a prison. The article linked is just a tiny snippet so I was missing context.

What a horseshit title.

It's not el Salvador's responsibility to transport him back to the US.

I don't think he is being stopped from leaving, but it's up to the US to make it right, not El Salvador

EDIT: it wasn't clear from the article that he was being held in a prison. My bad on that.

Absolutely should be released, but it is still not on El Salvador to send him to the US.

I think it's a good point. The hypocrisy and double standards have really come to the fore in the past 3 years.

However, I think it's partially due to a lack of empathy/inability to understand the desperation that drives some parts of the war machine, survive at any cost.

Land mines are a horror of war that bite long after the conflict ends. They are also one of the most cost effective ways of slowing/containing a large scale enemy assault.

Personally, I don't know where I stand on this news, existential threats shift viewpoints drastically.

I think it's fair to say: we should not use landmines, we should wish for other countries to not use them. However, I don't think that they should be demonised. And they should be used as "reasonably" as possible. (E.g. securing a border or military base, not near a residential area). Of course when survival comes into play, soldiers will do what they feel they need to at the end of the day, and who are we to judge from the comfort of our screens?

Absolutely it should be celebrated.

Once enough users are here, you can join a niche small instance that doesn't federate with as many mainstream ones to get that small community vibe. (Or better yet, make your own instance to build what you want)

The more people using federated social media instead of single-entity controlled social media the better for society.

Everything has a cost. Usually of the same type as what you are buying.

You can usually reword security/stability as a type of freedom. The freedom to have a guaranteed income usually costs some of the freedom to choose where/when/how you work. For example.

You might say that you will pay for the freedom to not have school shootings with the freedom to have free access to guns. You lose one freedom to gain another.

You are correct that to some degree they are antonyms, but I would say that it's freedom vs stability. It's just that security is a type of stability.

If you break them down more mathematically freedom is represented as infinite possible trajectories, which is in other words a very unstable position. In order to increase stability you must reduce the possible trajectories.

He did it twice. And it was very clear.

I would add that I think checking out and joining smaller instances is also a great opportunity. Distributes the user load across servers and being one of fewer voices in an instance means you have a bigger say in who you federate with. You also get to be a third party instance to most of the big drama and don't get judged just for your instance as much

Edit: also, if you like your instance, contribute to it!

Lots of great software already posted, but with some complaints about windows inefficiencies I can't believe no one has posted:

Microsoft PowerToys https://learn.microsoft.com/en-us/windows/powertoys/

Basically, it's a suite of tools that windows devs have made to make their lives easier while working in windows. Some features have made it into actual windows releases over the years, but most not.

It has an always on top, batch rename, customisable window snapping, better search, keyboard key remapper, mouse across multiple devices, colour eyedropper, and many many more.

Absolute must have for anyone that uses windows regularly.

I think the only time martial law can be seen as reasonable is in an outright state of war. And even then, only when it's existential.

It's kind of inherently the antithesis of democratic values.

I'm so annoyed at coverage of these issues and the economy as a whole. Journalists have to use the biggest numbers they can to make people think it's important.

Ok a 64% reduction in profits is not good. But that also means that the company is still profitable and wants to fire the thousands of people, and in so doing harm the local economy, that gave it massive profits for decades.

A 64% reduction in profits cannot be the company making a loss. Yet the article claims that BMW and Mercedes are "also making similar large losses".

Shareholders have been robbing employees blind for decades, and the second it gets a little bit less profitable we have to fire thousands of people?

And yes, I understand there must be some consideration of future proofing costs against a shrinking consumer base, but such drastic measures are solely aimed at preservation of shareholder dividends and value (see Boeing).
