For the stuff I do, I rarely use signed types. I find the example of finding difference between two numbers to be really silly. I don’t recall ever having to do anything like that, for a simple reason: I design my code so that I always know which number will be larger than the other.
Let’s actually talk more about this max - min example. Let’s say you calculated this delta. What is it useful for in your code? Typically, in real algorithms, what you want is to not only know the delta, but also which number is larger.
What is creepy about Anduril? Anduril simply sells weapons. There's nothing mysterious or nefarious about it. European countries want to buy weapons too.
If you read the article you sent me, you'll learn that, just as I said, you don't use sodium chloride, aka table salt, aka sea salt, for these purposes.
It’s about thermal storage, you don’t use table/sea salt for that, and you don’t need a lot of salt, because the salt is in a closed loop; it’s not being consumed.
Brine might be bad to the place you dump into, but crystalline salt is even worse.
Overall though, it’s just such a tiny concern. Ocean is huge. If we kill everything in a 100 foot radius, that’s 0.0000000008% of the ocean being destroyed. Less than a drop in a bucket.
Yes, and by shifting the labor supply curve you can make the laborers worse off, because it will often shift the supply curve of the product they’re making. If labor unions make you pay your workers more, you might need to raise the prices, which will make you less competitive, and reduce your sales, which can result in layoffs, or in preventing new workers from gaining employment.
Sorry, I’m not chilled at all by the prospect that the court can subpoena my data from Goole. It can already issue a warrant to arrest me, and to search my actual home.
I hate this change. I loved how the original Timeline worked, and now it's unusable. I don't care about courts subpoeaning my data. I'd love to opt in to previous status quo. I don't care about the loss of "privacy" in the context that was never important to me.
Most people are like me: they don't care about being protected from the courts, because the courts don't pose risk to them, and as a matter of statistical fact, they are correct.
No, they totally grew enough calories for themselves. My grandparents lived like that. They farmed around 15 hectares, which was actually quite a lot. You can easily grew enough calories for your family on 5 hectares, or even less if you have access to modern cultivars and artificial fertilizer. It’s just even poor people like variety, and will trade some of their crops for stuff they cannot make at home efficiently, like sugar, fish, or candy.
Prior to Industrial Revolution, nobody could go hunt in the woods, because the woods were King’s, and poaching King’s game carried death penalty. Situation was similar on the continent: the tiny slivers of remaining wood lands were off limits.
Granted, things were different in the New World, as a result of mass depopulation event following the Columbian exchange. But even there, the megafauna was hunted to extinction soon after the humans first appeared there.
Anyway, the point is that no, prior to Industrial Revolution, the world was of full of scarcity, not abundance.
The research shows that the tests are predictive almost precisely to the extent they test “meta skills”. We can even measure how much individual questions test meta skills vs specific skills. You can learn about this by searching for the terms “factor analysis” and “g-loading”.
Obviously, yes. This is not circular: it is by no means tautological that people who did well on test X will do well on a completely different test Y that tests different knowledge and skills. The fact fact that it does gives strong evidence to the value of using these tests for admission.
