It is a work of art!

It is a triangle. The abstraction of lines in non-Euclidean geometry are geodesics and just like three lines form a triangle, so do the geodesics. If you walked along the earth's surface from the equator to the North Pole and back, taking 90 degrees angles every time, you will have felt that you made a triangle by walking straight in three directions.

The reason the angle sum can be more than 180 degrees is that the sphere has a positive curvature. If you want one with negative curvature and less than 180 degrees angle sum, try to make one on the side of the hole on a torus (look up its curvature if my explanation was lacking).

EDIT: Picture for reference:

The answer is obvious. Depending on the curvature of the object the triangles have higher or lower than 180 degrees angle sums. Flat space just happens to have 0 curvature.

Did not know about this site. It was a nice read and their mission statement is cool. Thanks for sharing! :)

It is nice where possible and can help locally, but on scale it will not force through any changes. To see why, we only need to consider the historical material conditions that allowed the development of the current capitalist form in the first place. Small businesses where defeated by capitalists that could employ tactics the others couldn't answer.

In order to answer to the consequences of our current mode of production, we have to force changes to how production is carried out. Saying we want our products locally, ethically and environmentally made will only change their branding, not the fundamental exploitation in search of surplus value.

When you have to spend on things like haircuts, repairs, etc, keep the money in your social network.

While I agree with the idea of not buying garbage, there is absolutely no way we can unconsume ourselves out of the capitalist ploy to extract surplus value. Do not put the blame on people who try to (often) satisfy legitimate needs, but on those forcing labor to be spent at the cost of both the environment and workers themselves.

Ecofascism (not accusing you here) is not going to solve the climate crisis.

I like people who think critically themselves (and are sometimes weird in lovely ways). Often I find them to be leftists and/or Linux users. I encourage your independent thought as to why.

Yeah, hearing about how hard it would be to get tenure dissuaded me from pursuing my original dream of doing a PhD. In retrospect I think I am much happier where I am now than I would've been, which really is what matter the most to me now. Freeing myself of the obligation of attaining my goals was actually quite nice.

I misinterpreted your comment and was very pleasantly surprised that something named "rational wiki" would call him out for the crackpot that he is.

Yeah, this is not a nazi bar.

I am pretty certain our brains evolved to filter out friendly/known voices some tens of thousands of years (or more) ago. I feel tired sometimes before and after coffee, and often less so on coffee breaks because the real issue with coffee is that the caffeine can definitely disrupt sleep.

I understand you need consistency to not be engaged by sounds. I hope you understand that other people have other limitations, hence, again, it is your first statement I disagree with.

I see you repeating the claim that it makes sleeping more difficult, but I do think those that listen to sounds, be it ocean waves or someone talking, have the experience that it makes it easier for them to fall asleep.

Sure, there can be problems with sleep quality for numerous reasons. However, making a blanket statement that this disrupts the sleep, especially of those that have positve experience with it, is going to need some factual sources (that I do not think exists).

According to what I have read, it is fine if it is not too stimulating.

EDIT: Also, it is easy to take a break from coffee: It only requires not drinking a few cups. Either way it does not really prevent fatigue, at most delaying it.

How is it bad sleep hygiene to fall asleep to noise? If it is adequately non-engaging, it is pretty much the same as other white noise. Furthermore, it really depends on each person what makes them relax.

To paraphrase an actual sleep scientist (and not just talk out of my ass like most people do about health):

It is easy to see know if you are getting enough sleep. If you feel tired during the day, you need more sleep.

Still only because the DM decided to be nice about it.

That warning is the sickest burn I've seen on Wikipedia.

Realistically, how many people build applications themselves? Signal does not have reproducible builds (on Android at least) and depends on Play Services for notifications.

EDIT: Seems they have it now (since 2016). I am getting old.

Loved out of life 👻

This is called multi-seating and requires input handling of more than one keyboard and mouse (as well as other things). It is not really useful for that in the state shown above.

Also, reported income is not the same for regular people and the top 1%. Tax evasion techniques makes it seem as if they have way less income than they really have.

EDIT: I do realize some of this could be incorporated into the statement of your quote above.

The (then) right-wing Norwegian government (left-wing by US standards ordered a study because they wanted to claim this. The results (source in Norwegian, use a translator) were the opposite of what they wanted.

For example: "the businesses used more money on their workers when the stock owners were subjected to higher wealth tax" (paraphrasing here).

Is a car or shirt or house personal property?

Yes.

I reference "dignity" because it's part of "the unshakeable foundation of the Republic of Poland"

Yea, not sure I care about the right-wingers in Poland either.

cooperate with you if you remind them of the Soviet Union, and I expect that saying "we should remove the capitalist class" will do that.

Well, I think we should be honest about our intentions, unlike the capitalist class that tell you "brown people" or "the economy" is the reason they pay you slave wages.

What misinformation am I repeating? I wouldn't have written a statement that I don't think is true, so I suggest you point out anything you think is incorrect and explain your perspective, and maybe share a URL for some more interesting sources.

The part about seizing personal property to pay taxes, for instance. A progressive tax system can have bottom tiers paying no taxes. The right are those who impose high tax rates on the middle class and poor, in order to make them hate taxes.
