I don't think he really appreciated the danger of lead. Its acute toxicity was well-known, but not its chronic toxicity.

And plenty of stuff is toxic in large quantities but harmless (or even vital!) in small quantities.

You can't focus sunlight at the satellite distances. And this is a fundamental problem, the focal distance varies for each wavelength so your focus point will be smeared. You need monochromatic light for that (a laser).

Edit: and also don't forget that the Sun is not a point source and has an appreciable angular size, further making it impossible to focus it with a reasonably-sized lens or mirror.

You might be surprised, but a lot of people actually like "bad" versions more.

I don't like regular ice-cream it's just too rich for me. I experimented with making aerated (well, nitrogenated) ice-cream myself 20 years ago when I had access to a lab.

Hah. I have a homelab with a couple of sites, including a personal Forgejo installation.

Last night my server turned off because it went into thermal protection shutdown. Turns out, my all-in-one cooler has inoperative fans, which I normally never really notice. The passive heat dissipation from the water cooler is more than enough.

However, this time they hammered my computer for 12 hours with about 200 requests per _second_ to my Forgejo.

> Because AI cannot retain memories or gain experience or insight based on the transformer/attention mechanism powering all modern AI models, it follows that AI lacks judgment and can never be trusted to handle truly critical decision-making responsibilities.

There are multiple teams working on adding long-term memory to AI. This is not a fundamental problem.

Fine-tuning to store memory in the weights is something that almost works right now, btw.

Relativity is also responsible for a lot of weird behaviors of heavy elements, such as the color of gold. Or that lead is a good material for batteries.

Nice. Now just force stores to display actual prices with tax.

Most drones are controlled by humans, so they don't need neural networks. Larger drones still don't use anything too advanced, as specialized neural networks actually don't need beefy hardware.

Maybe this will change in future, but the US still has enough semiconductor manufacturing capacity to produce a few million chips for drones.

Why? Are you sure that the kind that you're eating is not shit?

> Problem isn’t with “tastes better and at half the calories”, no, it is actually for providing filler when the initial sell was using genuine simple ingredients.

So "ice cream desserts" use fake gelatin?

This kind of recipe is wildly irresponsible to actually sell. Raw unpasteurized milk _will_ cause health issues when used in large quantities. Ditto for raw egg yolks.

I lived on a farm during summers as a child, but I will not touch raw milk ever again after getting hospitalized with a bacterial infection from it. And the milk was from our cow, btw.

Egg yolks are safer, especially if you take care to extract them properly. Still not safe enough for mass production.

Most drones don't use anything cutting-edge. Even 15-year-old chips are more than enough.

The US can produce these chips. South Korea can also do that.

Which supplies? Batteries are produced everywhere. Power electronics are dime-a-dozen. IMUs, GPS chips, and CPUs are produced in Taiwan anyway.

There are no truly irreplaceable components there. It's going to only be a problem if China stops _all_ the exports.

Even then, a custom supply chain can be set up domestically. You'll probably have to limit the number of variations for these servos and motors, but you can produce them even manually if you absolutely have to.

So... Who's porting Doom to run on this?

We are making a niche model that we're now expanding. You'd be surprised how the general models suck for anything vision-related.

And even if you use all the tricks in the book to make them work for you, the cost can easily be 1000 _times_ more than the specialized model. Ditto for speed.

This is especially important for things like robotics or navigation.

One thing missing is that the population growth in the US is mostly reliant on immigration (https://www.census.gov/data/tables/2023/demo/popproj/2023-su...). And our most favoritest political party is working on stopping it.

It actually is, just not water steam. There's a hot springs resort in Alaska that uses pentane (boiling point 38C) to generate energy. The efficiency is terrible, of course.

You can put Noctua fans in server rack computers. I even modified my NAS to use them: https://pics.ealex.net/s/noctua-fans-ftw
