Maybe just use Starlink from the satellites, so we don't rely on a specific ground station. Starlink Ground Station Network is global, spread in many different countries and look more resilient than a single one.

That would require replacing all the satellites with new ones capable of doing that, which doesn't seem feasible. Starlink also doesn't have great coverage of the polar regions.

Starlink's laser system is already up and running. Back in January it was delivering over 42 petabytes per day:

“We're passing over terabits per second [of data] every day across 9,000 lasers,” SpaceX engineer Travis Brashears said today at SPIE Photonics West, an event in San Francisco focused on the latest advancements in optics and light. "We actually serve over lasers all of our users on Starlink at a given time in like a two-hour window.”

Most probably Russia will claim sovereignty over all of the Svalbards after the next big war and redrawing of borders, Stalin was too circumspect in not scaring the Americans into WW3 the first time when they had the chance to do it. All that because whoever controls the North Pole controls most of the Northern Hemisphere, it’s actually one of the very few “ways in” inside North America and control of the continental…

I for one welcome our new Polar Bear Overlords. (Hope the Russians don´t forget their rifles when they move in.)

I thought this forum still wanted to be on the serious side, so under that view look at the works of George T. Renner, in particular his World Map for the Air Age, published in 1942-1943. [1] [2]

As air-power started to be taken seriously with the advent of WW2 (some) geographers started realising that one of the shortest ways of getting from Europe to North America is via the North Pole, or close to it, anyway. Hence those maps I've linked to, which had the North Pole at their center, and that is because Renner thought that the control of the North Pole was similar to the control of the Northern Hemisphere. Related, a little bit later on ICMBs were meant to take the same route, give or take, hence why NORAD became a thing.

But, again, we can choose to take the "lol! lol! lol! The Russians and their shovels!" angle, which won't benefit anyone involved in this conversation, intellectually speaking.

Later edit: Additional resource, this study [3] titled: "The Hot Struggle Over the Cold Waters: The Strategic Position of the Arctic Region During and After the Cold War"

This paragraph there is a good start on how important were the views of people like Renner when it came to the Arctic, that is in the context of the US vs. the USSR/Russia (potential) confrontation:

> The first to focus his interests on the significance of the strategic position of the Arctic was George T. Renner, when in the 1940s, based on a map with the North Pole at the center, he estimated the opportunities and threats associated with this new perspective. However, the increase of the Arctic’simportance is inextricably linked with the development of technology which allowed greater exploration of the region. Shortly after the outbreak of the Cold War, in the rhetoric of the United States, the High North began to be identified as a “mighty” and “important” region.44 Hence, the geostrategic role of the Far North was fully revealed during of the Cold War, when it was possible to observe real military and political tensions on the polar waters and islands.

For anyone curious, I found the relevant sentence. An astonishingly counterintuitive almost throwaway remark by a world's expert sent me on a deep dive on what else can and does cause lung problems. Dr Martin Tobin says it at 3h 02m 40s... https://www.c-span.org/video/?510467-1/derek-chauvin-trial-d...

What was your takeaway? Any added insights/reading?

I am aware there is a lot of complexity (obviously) in why people develop lung cancer, or any illness for that matter, but within that assumption was smoking being far worse than it actually is. Reading further, and this may also seem obvious written out in this simple form, the cancer numbers for people in homes using coal burning for cooking food varies hugely depending on the coal. And that the incidence of lung cancers in 'never-smokers' is rising rapidly globally.

Just in case why people are wondering why cutting of internet for an arctic island is a big deal. What many might not know is that Svalbard is home to the northernmost satellite station in the world. It is just one of two stations that can communicate with polar orbiting satellites each day. ESA and NASA as well as other civilian organisations are present there, and the station communicates with well over a hundred s…

Time for a Starlink backup then

You can look at the https://satellitemap.space/ to see that starlink isn't (yet) too feasible in the northern/arctic areas. Even in the Nordic countries the connections are not that great.

Imagine a scenario - a restaurant owner is insured for $3 million dollars for the business and structure (not atypical). Business isn’t doing great. The place catches on fire and burns down. All the business assets and the structure are lost, so the business needs to shut down. If arson wasn’t an exclusion; 1) why would anyone look closer to figure out if it was intentional or not? Assuming no one was injured. Who ha…

I don't understand your example because from your description I can't tell who set the place ablaze. If it's the owner, then it's insurance fraud, and it has nothing to do with moral hazard. If it's not the owner but say a random crackhead, then I also fail to see how it qualifies as moral hazard, and if the insurance doesn't not cover them nobody will (because the arsonist is insolvent and will never be able to pay…

All I can say is you clearly don’t understand what moral hazard is, because my example is a textbook (literally) example of it. [https://www.merriam-webster.com/dictionary/moral%20hazard][h...

If the owner won’t lose out on the payout from insurance by committing arson, or could plausibly get away with it without getting caught, he is experiencing a moral hazard to commit arson.

It’s only insurance fraud if he lies to get a payout from insurance. Which means the insurance policy would need to have an exclusion to not pay him out if he committed the arson, so he lied about it. If it did not have that exclusion, then he doesn’t need to lie about it, hence no fraud.

Either way, that the insurance policy would pay him if he burnt his place down is literally the moral hazard. It’s called a moral hazard because it creates an incentive for him to commit an immoral act that he otherwise would not. It’s existence is a hazard to his morals.

That they would exclude if he did it himself, and would investigate it, is what the company is doing to attempt to mitigate that moral hazard. But it always exists.

This random example is interestingly at odds with all the other definitions and example on that very web page!

> If the owner won’t lose out on the payout from insurance by committing arson, or could plausibly get away with it without getting caught, he is experiencing a moral hazard to commit arson.

This makes zero sense, because in that line of reasoning, the moral hazard is always there no matter what the policy is about arson: “all the owner needs to do” is to commit arson without being caught, which is exactly the same thing whether or not arson is excluded from the policy, since committing arson on your own good to receive payment from insurance is insurance fraud anyway.

The only thing that changes if arson is excluded is if the arson is committed by somebody else!

> Either way, that the insurance policy would pay him if he burnt his place down is literally the moral hazard.

But you are making things up! This particular moral hazard would only exist if insurance fraud was not a crime in itself, which it is already! And as such, there can be no such moral hazard, because no insurance company is to pay a dude that burns down his own place no matter if there's an exclusion about arson in their contract.

> That they would exclude if he did it himself, and would investigate it, is what the company is doing to attempt to mitigate that moral hazard. But it always exists.

The company would have to do no investigation and it would do no mitigation, as it would be the police investigating to protect public order.

AS I said before, the moral hazard would only exist in a place where insurance fraud is not recognized as a fraud.

Saying that this a moral hazard is like saying that bank robbery is a moral hazard on the perspective of banks, and that's clearly not what this phrase means.

This is why when the USS Nautilus became the first submarine to transit the arctic entirely underwater, traveling from the Pacific to the Atlantic via the North Pole, it was such an important event in the Cold War. It gave credibility to the submarine fleet becoming part of the nuclear triad, the use of nuclear power for propulsion and life support, and long distance navigation without any external references (can't use a compass up there!)

This was the big one for me too. The juxtaposed healthy versus unhealthy lungs resemble an uncooked chicken versus a roast chicken which was left in the oven for 30 minutes more than necessary. https://www.scotsman.com/webimg/legacy_elm_28724349.jpg?crop...

The antismoking PSA that made the strongest impression on me, by far, was the one that showed a grandfather encouraging a baby to take a step. Eventually, the baby starts walking, and rushes over to the grandfather. And through the grandfather, who fades to translucency. It wasn't just me; that PSA made enough of a splash that it was called out on Friends . I've tried to find that PSA in the past, but with no success…

There have been some Oceanic anti-speeding ads that had the same effect on people, apparently. There's one where time freezes right before a collision and the person at fault apologizes for the little boy he's about to murder. There's one where the driver is talking to the ghost of his friend who died in a car crash. There's one where the grim reaper spins a roulette wheel every time a driver makes a mistake at an intersection. There was one where they rewind time, nudge the speedometer slightly lower, and resume normal time, and a fatal accident (pedestrian hit by car) turns into a bruised leg.

The Shannon limit is constant if you assume reasonable but idealized SNR values for the medium, and gives you a real "law of physics" upper limit ... typically still many orders of magnitude beyond what we can transmit today. But it's amazing how effective DSP can be; trellis coding managed to get modems to squeeze right up to the Shannon limit of POTS telephone connections.

> The Shannon limit is constant if you assume reasonable but idealized SNR values for the medium The Shannon limit is changed by changing technology over the medium, not the other way around. If you signal with light on/off pulses, you get one limit. If you add polarization tricks (using different physical properties and tech), you get another limit. As you add QAM and a zillion other tricks, you get another channel…

There is also a technology-independent Shannon limit for a cable. You can calculate Shannon limits based on the bandwidth and noise of your specific fiber-optic transceivers, which can improve, but you can also calculate one based on the cable itself.

The Shannon limit already accounts for any number of channels and any level of QAM.
