I am not capable of judging whether the pressures against Greenland/Denmark and Canada are real, strategic noise, or a joke. The tariffs are a different matter. Anti-US tariffs and anti-US ownership laws are commonplace, and Trump's tariff actions are being used to force mutually reduced tariffs or a level playing field.

The US has not been trustworthy to allies for at least 50 years, and not trustworthy to its own citizens for more than 90 years. There are a great number of countries that have never been trustworthy.

The U.S. could be a net exporter of vegetables in a couple of months if it stopped converting corn into ethanol.

I have space heaters with a switch on the bottom that turns off the heater when it falls over or is lifted off the ground. Imagining lidar or an ultrasonic detector on the bottom of what was previously a $30 space heater gave me a good laugh.

Imagine how good Voyager would be if those people actually were geniuses, instead of just having sex with geniuses.

maladroit: "Covid vaccinations saved lives and reduced the severity of cases."

Mirnotoriety: "Vaccination didn't prevent you getting Covid."

maladroit: "And now you're just lying."

If "Vaccination didn't prevent you getting Covid" is a lie, then vaccination prevented COVID in all cases. However, your first statement was "Covid vaccinations ... reduced the severity of cases." It is not possible to have a reduced-severity case without having a case. You have contradicted yourself.

Mores (2 syllables), societal standards. Morays are eels.

My experience with KDE has been that some changes irreversibly break existing behavior. Window toolbars disappear along with the mechanism to restore them. A second desktop task manager appears with no mechanism to move it or remove it.

I may be mistaken, but it appears that KDE has an update mechanism independent from Fedora's dnf, and I've found no way to disable it.

The official documentation is inadequate and seldom applies to the version I'm using. I often have to go to reddit to find cures, although as expected they work less than half the time.

That's at least 3600 Calories a day. He will remain very sick.

Money is what is traded for goods and services. If there aren't enough goods and services, no amount of money suffices.

Apart from the brain, that doesn't grow new cells.

That is an old claim that has been shown to be untrue. Search for "brain cell growth" and look at some of the results.

There is not enough work for everyone to earn money.

Prove it or provide a credible source. Just stringing words together is not a dependable way to generate truth.

You could overcome this problem with some kind communism

Communism assigns work, goods and services at bureaucratic whim, and by thus removing any mechanism connecting supply and demand, guarantees misallocation of effort and resources. Absent communism, a person needing food could take the most direct path by doing work to grow or gather food. Money does not even need to enter the equation.

So much of that just doesn't follow from the premise. For example, IVF would make pregnancy possible for a woman who is so old that she's already run out of available eggs.

The mechanism needs to be examined. Only allowing fruit flies to reproduce when they've reached old age means that short-lived fruit flies don't get to reproduce; that's the evolutionary pressure. If the researcher could know in advance which fruit flies would remain fertile longer, they could mate earlier and still achieve the longer lifespan in the group. The idea that delaying reproduction is in itself the driver of long lifespan is close to Lysenkoism.

we have no idea which genes will be beneficial to survive some potential species-ending event.

That's why scientists study what genes do, and why some software is designed to predict what genes do without actually testing them. The hope is that eventually we can control human genetics in a manner that improves many aspects of our lives, including lifespan.

Telemerase restores telomeres.

The claims I've read indicate that the problem is valve seat wear, not valve strength. The most recent I've seen say that the problem is with engines run at high power for long periods of time, i.e. marine engines and racing cars. It looks like the carmakers were barking up the wrong tree.

As side notes, it was the problem of lead contaminating catalytic converters that finally pushed lead out of gasoline, and I guess that hardening the valve seats in an engine's manifold is more difficult than hardening valves.
