Sorry, I didn't get it. What was the 'right' answer?

Isn't that the case though? Where's the separation of powers or the rule of law in the US?

To be clear, I'm not favoring any kind of such action, just holding the honesty of the statement.

> The fact that such a fuss is being made about low-grade oil is a concern in itself.

Keep in mind there's a lot of 'idle' refining capacity at the southeastern coast of the US which was built for heavy oil.

A bit of a tangent, but the more complete reason depends on what civilization (Aztecs/Incas), the common factor is an extreme loss of life due to old world disease.

Additionally, for the projectile velocity at the time the gambeson-like garment the Aztecs had available was surprisingly effective.

Funny if not tragic. I was impressed at how good the styling of the page was until I realized the css did not load.

You can use some form of real extensions, e.g. the extended real line (+inf, -inf is often useful for programmers) or the projectively extended real line (+inf = -inf).

This is not about infinity in math not being a _specific_ value, it can certainly be (the actual infinite instead of potential).

It's simply about design and foresight, in my humble opinion.

I was fascinated when I first learned of [FreeBSD Jails], I wonder if right before containerization became a thing the concept was developed further for its requirements (could it have been?) it would have offered a more efficient containerization platform.

Maybe, but at least I believe there's plenty historical evidence for a different interpretation than: "russia and china big bad, their values are wrong/not aligned with the west"

Thank you! The article was "too clever" for me.

I had a hard time trying to parse something understandable from the article.

This is what I got from it (I'd be happy to hear someone informed correcting me/confirming). (excerpt from a discussion yesterday I had with some friends not too math inclined)

What it seems to be the articles claim is that, you could define a scaling operation in the angles you performed, finding some constant scaling factor (say alpha) and running the operation twice to reach the identity (rotation 0 compared to baseline), e.g.:

I = R ⊕ (α.R ⊕ α.R)

In their example that would be something like (with alpha=0.3):

I = (rad(75).X ⊕ rad(20).Y ⊕ ...) ⊕ (rad(0.3x75).X ⊕ rad(0.3x20).Y ⊕ ...) ⊕ (rad(0.3x75).X ⊕ rad(0.3x20).Y ⊕ ...)

Remembering that our rotation action is non-commutative, e.g. `aX ⊕ bY != bY ⊕ aX`.

The interlocutor on the other end experiencing time (or reasoning) at a different scale is an interesting case too, imagine a week feeling like centuries to them.

I really have a hard time understanding this train of thought.

One could say these sentences are also a product of "its culture".

The world is not black or white, good or evil. Things are more nuanced and complicated than advertised to be.

I'm not the single source of truth either, but I think there are lots of resources for people interested in avoiding propaganda and trying to understand things more deeply.
