Apparently Wired is now pay-walled. Here is another article about things:

https://www.space.com/space-exploration/satellites/this-comp...

...I wonder what the cost per minute is to use this? Seems like each mirror can only be used by one user at a time. Unlike a Starlink or other communication satellite which can be used by lots of users simultaneously. I suppose eventually there will have to be restrictions on these satellites, so that you can't use them to harass people. Or use a bunch of these as a concentrated solar forest-fire starter.

I know we can be all righteous and intellectual on HN. But the article pretty much glosses over the large number of people who are afraid of the dark. Not afraid of crime in the dark. Actual adults who are apparently having a visceral reaction to the dark. What percentage of people is this? What percentage of those would adapt in a positive manner?

FedNow

There is no recourse if something goes wrong with FedNow, right? Like you get scammed, and the scammer just keeps the money. Seems like a pretty big difference (in theory anyway) to PayPal. Although I'm apparently not the right guy to ask, since I really don't see the use case for PayPal vs. credit card.

If the spatial extent of the proton is not infinite, this would imply that the charged quarks making up the proton are accelerating. Why aren't these quarks then emitting electromagnetic radiation, thus slowing down? I thought electrons were essentially standing waves around the nucleus, and thus not accelerating. Maybe there is a good youtube video explainer? Seems like there would also be an associated temperature and blackbody radiation of these quarks.

I guess it doesn't matter if the Iranian people want regime change in their country. Lots of people want lots of different things (plus a pony). It only matters what they do. And it doesn't appear that they want regime change enough to take the risks of making it happen. I suppose this is the hubris of polling.

A.) Would you be happy if the government changed? (85% approval)

B.) Are you willing to potentially sacrifice your life and the lives of your sons to change the government? (3% approval)

a concentration camp

Most people at these facilities can leave at any time, right? Just so long as it isn't back into the United States? They can return to their country of origin, or another country. I'm sure someone will offer a correction if this particular facility was holding people for other crimes in addition to their unauthorized alien status.

Some of the people given 30 weren't even at the protest.

That by itself isn't a convincing argument. You can't plan a bank heist and be waiting at your safe house and say, "I'm not guilty of anything, because I wasn't in the bank!". The mafia guy doesn't get to say, "I didn't actually whack the victim, I just nodded to Joey, and he did the whacking".

...maybe this is mostly a thing in common law jurisdictions? Maybe there is a lawyer here who can point us to a interesting history of conspiracy in common law vs civil law jurisdictions? Also of interest might be things like:

Isn't the volume of orbits pretty large? Maybe someone can check my math. According the the article the mega-constellation would be at an altitude between 500 km and 2000 km. Radius of the earth is ~6400 km. So the volume of the orbits would be: 4/3*pi*((6400+2000)^3 - (6400+500)^3) = 1.1e12 km^3. I guess some of the orbits would be harder to get to than others (polar, etc). Also, what is the story like for improvements to glare. Seems like any reflected sunlight off of solar panels is wasted photons. Can coatings help with that?

but your doctor is heavily incentivized to use the new version as the markup on the drug is much, much higher.

I don't think it is normal/usual for doctors to receive any benefits or profits from which drugs they prescribe. Other than golf outings with the drug company reps? Is there something I'm missing?
