Practically, anyone with access to the Baltic Sea, boats, scuba equipment, underwater explosives could do it, but they couldn't do it undetected. This area is under surveillance from Sweden and Denmark.
If you want to do it undetected you need to do it completely underwater, including ingress and egress, and that absolutely limits the potential actors.
Another issue with game dev for games that release on PC is that devs are usually on very high-end machines. NVMe RAIDs, 3080's, etc. Great for productivity, but there's very little dog fooding on low-spec machines.
Perhaps your friends parents were over-careful because their kids kept breaking bones? Kids are different. Mine is very risk-averse and has essentially never hurt himself bad. I was the same way as a kid. His friends are daredevils who hurt themselves constantly.
Also, when it comes to "our parents in the past would let us do anything and I came out ok" sounds a bit like survival bias to me. In Sweden, far fewer kids die today than in the 70s, so perhaps there's some merit to bicycle helmets, safer playgrounds and not letting your kids eats whole grapes unattended before the age of five or so etc.
The actual scanning might be slower, but the queues are much shorter for self-scanning at the stores where I by groceries.
Also, where I live we have portable scanners. You pick up a scanner when you enter the store, you scan all your groceries and put them directly in the bag (or under the stroller) and when you reach the exit you leave the scanner and pay at a terminal and off you go.
That's only true if Boeing was the only manufacturer that builds this category of planes (they are not).
Boeing has an issue in their planes that the A350 doesn't have. So if the price of 787's goes up because it needs to go from unsafe to safe, then airlines can buy A350s instead.
This isn't about efficiency or cost per passenger mile I think.
The A380 was a bet that the hub and spoke model (where passengers travel to an airline's hub in small planes and onwards from there in larger ones like the A380) would continue to rule the industry.
Instead, what happened was low cost carriers flying passenger directly to the destinations. It appears that passengers prefers that, which is why the B797 and A350 exists.
The women who report these issues has no obligation to solve the problems, they're simply pointing out that they exist (since for a long time, people wouldn't believe them).
If you can restart without downtime you don't need a hot config reload. Suddenly you can treat config as immutable and discard an entire category of bugs as well.
The _entry_ salary for a RN in Sweden is about 25k SEK per month . The _median_ salary for a dishwasher is 17k. The rest of your statements are about as factual as that one.
The other responses to your posts are great, but I'd like to add one thing to them;
Why are you equating low barrier of entry with quality? I think MongoDB ought to have taught everybody in this field that you can have a low barrier of entry and still be a crap product.
Why would it be more of a problem with refugees than other, paying guests?
Afaik, most US citizens staying at Japanese AirBnB's (for example) do not speak Japanese nor know the local culture. Do you think that's a problem as well? When I stayed at an AirBnB in Italy I knew nothing about the local culture nor spoke the language, nobody thought that was an issue.
