What’s wrong with, say, canned beans in water? I feel like you’re painting with too broad a brush there.

I think I did napkin math once that included cost of labour, and surprise surprise, mass production works. Just the energy is a good point too, though.

It sounds like energy pretty cheap right now. But, it’s also artificially cheap unless you have a lot of renewables on your grid, and somebody somewhere is going to pay for those emissions.

I didn’t do bread - maybe I should reconsider that one, per the other users here.

Yes, you’re allowed having hobbies. Not everybody is looking to do it because they love it, though, and people plowing massive time into saving a few bucks with DIY projects is a very real thing. So, it’s probably good OP mentioned it.

What if you wake up from the Matrix and it turns out the world actually descended into an ice age?

I mean, it’s a silly, kinda extreme scenario, but we’re talking about big picture stuff and you can’t ever convince me would cover it as well.

(it wasn’t until years later that I learned the full story behind that)

Okay, I can’t be the only one that’s kinda curious about your trainwreck neighbors. Obviously they fell down a conspiracy rabbit hole, but was there more?

I’m like 90% sure this is sarcastic, but you never know.

If it’s a really reliable source and sounds plausible, very little. Iran hit a hospital in Israel recently.

If it’s some random person and sounds plausible, probably many repetitions from unrelated people in unrelated contexts, with some time as “word is” after a couple or few mentions. Airport security is theater and misses actual weapons all the time. I guess I should add the caveat that if it’s something easily refuted like “TSA hires out of malls” it gets promoted to fact faster, because of Cunningham’s law.

If it sounds implausible, a lot. Like, it might be a thing I painstakingly confirm or deny over the course of years. Thermodynamics is always explained in a way that has massive gaping logical holes. It obviously empirically works, but a rigorous derivation without any sneaky tricks would probably imply a proof of P!=NP - and it took me years to work my way through enough papers and literature to confirm that.

If it’s a source or type of source with a history of making up the sort of thing they’re saying, infinite - it will be all noise regardless of how much data there is.

Laying it out like this, I clearly put a lot of emphasis on the motivation and past track record of sources. There’s so many things to see and measure, far too many, and there’s also lies and mistakes, so I guess one has to. That’s probably been true since the stone age, and probably drove some human evolution, although it’s intensified quite a lot in recent history.

Note that even facts are still subject to skepticism, discussion and revision. Absolute certainty it it’s own beast, and it’s not a universally agreed-on fact that it even exists.

Interesting how Wikipedia handles slashes in the title.

Good to know! Although I have to wonder if that’s true for programs more recently set up as well. That was >40 years ago.

You’re from .ml, so we might not be working from the same facts, but I’d put Putin ahead of Trump at the moment for sure. Trump has more long term evil potential basically just because he’s in a very vulnerable but powerful country.

Gaza vs. Ukraine is the obvious comparison for Netanyahu, and it probably depends on how you measure it. I’d expect there’s more actual deaths in Ukraine, but it’s a more populous country, they’re more likely to be military casualties and the non-lethal misery dealt is much lower. It’s even harder to factor in Russian operations in Africa and the rest of the world, although they’re a significant source of brutality as well.

Ah, so it dovetails with the whole “children get a name reasonably fast” thing. I was interpreting that as “ever, in a natural lifespan”. My bad, haha.

I suppose a counterexample to that might be cultures which do not use script in general. Then, obviously, there’s no Unicode characters for these non-existant glyphs.

True, but there’s little risk of a name being entered into a form without some kind of transcription.

That’s pretty mean, bro/brah/other.

Even in the days of catapults, rough formulas for the effects of gravity made them work a lot better. Knowing “it goes down” can do a bit, but not everything. If you somehow didn’t even know that it would be useless.

If the plane doesn’t pass through $0_V$ then how would that 0 be the image of some point ?

Can I ask why you wanted a proof, exactly? It sounds like you’re just beginning you journey in higher maths, and perfect rigour might not actually be what you need to understand. I can try and give an intuitive explanation instead.

Does “all dimensions that aren’t in the range must be mapped to a point/nullified” help? That doesn’t prove anything, and it’s not even precise, but that’s how I’d routinely think about this. And then, yeah, 3-2=1.

(I didn’t learn projection I think, only examples when learning matrices).

Hmm. Where did the question in OP come from?

They’re abstractly defined by idempotence: Once applied, applying them again will result in no change.

There’s other ways of squishing everything to a smaller space. Composing your projection to a plane with an increase in scale to get a new operator gives one example - applied again, scale increases again, so it’s not a projection.

No, we’ve heard they have some kinda enriched stuff, some centrifuges and could maybe someday have a bomb for decades. It’s a bit less theoretical now, they’ve been gradually enriching more and more since the US broke off the agreement:

In February 2023, the IAEA reported having found uranium in Iran enriched to 84%. The Iranian government has claimed that this is an “unintended fluctuation” in the enrichment levels, though the Iranians have been openly enriching uranium to 60% purity, a breach of the 2015 nuclear deal. In 2024, Iranian President Masoud Pezeshkian expressed interest in reopening discussions with the United States on the nuclear deal.

They have a significant amount, too, and if I were them I would be hiding it carefully in non-obvious places where it can’t be buried by an airstrike.

What do you mean? Israel is doing Russia a solid for some reason?

Also, nothing has been redirected yet. It takes a while for stuff to move through the military supply chain and into the hands of Ukrainian forces, or Israeli ones, and even then you’d need the US to pass different funding legislation.

So what though? “We’re the baddies” has the opposite of mass appeal, even in other cases where it’s true and makes sense. They can shout at clouds all they want, along with the flat Earthers.

Lol, that’s a good point.

Actually, a piece that only moves or moves differently in the presence of another sounds like it could be interesting.

Some of those queens have awfully provocative curves. /s

They’re all part of a conspiracy community where they think every nation or group the West doesn’t like is good and, less plausibly, working together. They take issue with anything that goes against that narrative.

Honestly it seems goofy but harmless to me. But, many people take personal offence. And they did make Lemmy.

Sure, why not. And they can do the same over to their side. And stealing certian content from Reddit would also be good.

I assume crossposts are handled properly by Lemmy’s feeds? I don’t think I’ve noticed duplicates much. My answer would change if not, because there’s going to be no way to predict people’s replication preferences.
