Of course it is, if you have offshored energy-intensive industries.

Good point. Only have one new tech at a time.

Surprised they are not using linear opposed piston crankshaftless generators to make an extended range EV aircraft.

Smaller, lighter, simpler, cheaper, and more flexible about fuel.

Things can still go wrong locally, for you and yours.

I recommend "Practical Doomsday" by Michal Zalewski. [1] It's useful as a set of topic reviews and checklists if nothing else.

Fernandez-Villaverde says he goes to each country's national statistical agency's website, and uses their numbers for births and deaths and population, and computes fertility and replacement rate, and the trajectory of population for each country from that.

He says he has no idea where the UN gets its numbers, despite asking several times. He is a professor of economics and demography, so he's not going to just make stuff up.

The tech connection on this is that phones expand the radius of the circle of peers - people that a given person can see and copy. But most of the problem is as Fernandez-Villaverde says: modernity itself, the expansion of money into more and more areas of life.

That's why the form factor should be a wand. Flourish it to activate, and speak your spell.

TL;DR

And saw a few AI tells on the scroll down. The use of the the word 'honest' in any of its forms, and short sentences in headings.

Rule One for writers: respect the readers' time. Strip out every unnecessary word. Every.

Germany had no good alternative because its politicians deliberately put it in the position of having no good alternative.

Something is wrong with Germany. Go to Our World InData's Electricity Production per Capita page and have a look at Germany, Vietnam, and say Israel.

In accounting this is the concept of "materiality". If some asks "is this material?", they are asking if it's worth spending significant time looking at it or deciding.

Remember to * 3 when assessing. Choose wrong, and you do the job, undo it, and do it again.

Early on Raspbian didn't specify noatime or even relatime; every time something was read off disk, a write happened.

Let alone things like putting /var/tmp and/or /var/log in RAM, or long commit intervals.

No idea what the current situation is; Pis are too dear for the likes of me now.

On doctors, I read a substack by a doctor who stopped using an AI notetaker after trying it for a year. They weren't his notes, and there was too much extraneous detail.

Can't find it with a quick search, but the point of the essay was that making the notes by hand reinforced the essentials of each case in the doctor's mind, so they were there for the next appointment two weeks later.
