No I reacted to this too - ferromagnetism is one common magnet sure, and I was thinking "the other is electromagnets, in motors". And then it came as "antiferromagnets". Bisarre.

(I do not hold phd in magnetics)

How does it work if I have a US credit card and use it abroad? Do I still get the kickback even though the merchant fee is capped?

This feels like a potential arbitrage opportunity... I live in Sweden, but if I can use a US credit card I can get high rewards?

Is that actually the silicon that's on top of a cpu?

I've always assumed the silicon is super thin - "wafer" thin. And then some material is added where the bonding wires etc are embedded in and the pads or pins are attached to.

For sure it's like this on newer CPUs, where there is not a single piece of silicon bit rather multiple ones with interconnect between them.

There are products in this space, eg https://www.crysound.com/

Very cool stuff, can be used for drone detection at up to 200m. Accuracy is not super good, unless you make mic spacing a bit large.

Yeah, I was looking at the same chart and was very surprised at where the curve is relative to opus... Feels like sonnet 5 is "what if opus had an extra-low effort level"?

"Internal power supply, AC power 110-240V"

I wonder if they mean that? Japan is 100V.

It's a couple of months since I did the calculations, but I do believe 2035 is for all energy, not just electricity.

It's easy to drag out a flat line in an exponential graph - but the line better start bending soon or we'll end up with a truly mind boggling amount of solar energy.

The growth of solar is astounding. I dug into data a while back and tried to do some visualizations of it, mainly for my own understanding:

Solar is already by far our cheapest source of energy. As solar expands, the learning rate means solar will be even cheaper. We should expect solar to be the single largest source of energy on earth by 2035.

See, this is why I put "inmates should have decent drinking water" first in my comment, and "inmates should have clean water" as the very last words.

It seems to me you are making the exact error in argument I react against. Stop making everything a "human right". You see, in the end, when you've made everything "human rights", the whole "human rights" concept will cease to have any meaning whatsoever and you will have lost.

Of course inmates should have decent drinking water.

But I strongly disagree with "human rights" that are defined this way - something someone has to go out and bring to you.

A human right is something that someone cannot take away from me. Free speech is a human right. The right to life.

A "human right to water" combined with a "human right to housing" implies that if I walk aimlessly into a desert and decide to stay there, it is my human right to have people bring we water and a place to stay. Other people not doing so is against my human rights.

That's just... dumb.

And, again - inmates should have clean water.
