Thank you for answering. I have so many questions but I'll start with this... When I ping an ipv4 address from outside the home, if something responds to the ping it is my modem/router, right? As in even if I had no computers in the house, you couldn't tell the difference when you ping my ipv4 address, right? My Internet service provider owns my IPv4 address, not me, right? What changes with ipv6? The ISP still owns the IP addresses and is free to reassign them wherever? It isn't like a phone number where I own the number and have a right (in the US) to port it?

Right. IPv4 addresses are expensive, so it's uncommon to have more than one at home.
> What changes with ipv6?
Not a lot. You just have many addresses instead of one. If there were no firewall, someone could ping your router or individual devices, as they have different addresses.
> The ISP still owns the IP addresses and is free to reassign them wherever?
Yes.

Correct. You would need direct BGP access to use a portable IPv4/IPv6 address. That generally is not available on residential connections.
But having 1-2 cashiers is only the norm now because of self checkout. Prior to self checkout there used to be nearly all lanes staffed at our local grocery and wait times to checkout were low.
Well, not at my local Coop. They have three cashier stations, nowadays one or two of them are manned (and the third person is free to assist customers where needed).
In my other living place, Japan, the MaxValu supermarket has, I think, around ten cashiers - not only that, those cashiers are super fast and use double-buffering for payment: You can pay while they're already busy with the next customer.
But still - they have also introduced self-service. They still have nearly the same number of inhumanely fast human cashiers but they now also have lots of self-service desks (and a person there to assist anyone needing it).
My coop has the worst of all worlds. There used to be four self checkouts, but they removed two during covid, and another one after it developed a fault. So you have one self checkout, with a member of staff that has to juggle baby sitting it and manning a basket checkout. It would be much quicker if they just removed the last self checkout and had the staff member man the checkout full time.
Yep, had four dead ash cut down last year and a whopping 22 dead ash cut down a few weeks ago. The grub form of the ash borer can be found in the firewood rounds.
These results seem inconsistent with the current understanding that the majority of the sugar in honey comes from fructose, and as such can be very damaging to the liver (fructose is a major contributing factor for 'fatty liver disease.') 'Use in moderation' is a fine cover-your-butt, but how many people do you know who consume anything in moderation, especially in the USA?
In moderate quantities, fructose cannot be harmful.
Nevertheless, with easy access to concentrated forms, like sugar, but also honey and dried fruits, it has become possible to eat too much fructose per day, which is guaranteed to have bad health effects, like damaging the liver.
The recommendation that I have seen is to eat up to 50 g/day of sugar, i.e. up to 25 g/day of fructose.
When eating only fresh or defrosted fruits, it is easy to follow this, because the upper limit corresponds with around 500 g of most cultivated fruits or with around 300 g of the sweetest fruits, like grapes or fresh figs.
On the other hand, a single chocolate may contain more than 60 g of sugar.
Excellent points! You're quite right that there are a lot more things we could do to improve the high availability in the Stack Exchange environment. Unfortunately, I was hired well after the environment was designed so any suggested changes would need to not only pass the rigors of review by the team but also be able to handle the load that stackoverflow.com generates. Changing pieces at this point would be nontrivial and difficult to get approval on if it meant that we'd affect performance of our main property.
That being said, I'm 100% in agreement with you that the two options you supplied would be wonderful additions to our environment.
This is a really good point and I appreciate your viewpoint, but just because I wrote the article for/about stack exchange it doesn't preclude me from having done it differently at a prior employer.
