  • Yes, if the panels were in outer orbit, and mostly powering things outside our planet.

    A little simplified energy cannot be destroyed only change form, each time it changes it loses a little bit of energy to heat. Over time that means all energy will become heat.

    So the only way to not heat up the earth with energy is to either make sure it doesn’t get to earth, or that we let it out.

    Orbital solar cells could keep enough light from reaching earth to cool it, but releasing the energy dirtside would mostly cancel that out. So, we cover the earth orbit with panels and use them to fuel space things.

    All of this requires more tech, a lot of resources and time to prepare though. And also a feasible way to store and use that energy in space. Maybe we shoot batteries at a moon base or orbital mining operation?



  • Is it though?

    We have tons of workers in hospitality on work visas (hotels, tourism, restaurants), we have care staff, doctors, IT professionals, project managers, process managers, engineers, management, PhD students (which is an employment here), finance bros, even life coaches on work visa.

    In my specific country they also take no extra risk other than having to culturally and institutionally train you.

    It’s definitely harder than doing things at home, and scarier, but it’s entirely doable. In four years we’ll see if there’s gonna be another US election, regardless you’re gonna be 4 years older. Either you stay and hope to weather the US, or you go try building something you’ve chosen for yourself.

    It’s not for everyone, and it’s a lot more comfortable being with devil you know. But don’t pretend it’s because the process is impossible.







  • I’m not sure what you mean is hard? Besides uprooting and establishing a new life in a different culture ofc.

    To my country a travel visa of three months is automatic/not needed from the US.

    A work visa requires proof of employment at a more than minimum wage job, something like a skilled chef, contractor or entry level college grad job qualifies. After two years you can job hop, four years you get a permanent visa, after five you can apply for citizenship.

    Requirements at each of these steps is that you can show you have a valid passport, the means to support yourself (and family) financially, are following laws and regulations, and remember to file the paperwork. No tests, no language requirements, just bureaucracy, patience and making a new life.

    If you’re in a high demand profession, a work visa takes 90 days to get and is valid for at least two years.

    This is for my country, you can typically check with the consulate for whatever country you’re interested in and they will happily inform you.



  • Profit, price pressures, inflation are not necessarily meaningful terms in a different system.

    What exactly do you mean by that?

    In a circular or planned economy, those aren’t really significant measures, neither in a subsistence living context. Which are strategies that have housed all of humanity until the last few hundred years.

    In a post-capitalist economy, we might be able to provide the human necessities without exploitation. I don’t know how, but I know it’s not through more capitalism.

    Homes have been built for many thousands of years longer than we’ve had those as concepts.

    If you include cedar bark as a major construction material then sure. Not knocking cedar bark here - it’s great. But not quite the same investment in time or durability.

    As mentioned in the last reply, the Palace of Knossos, as well as the Petra were marvels of craftsmanship and engineering, staggering investments, and have stood for over 2000 years. Would probably have survived longer if maintained properly.

    The pyramids, the Mausoleum of Halicarnassos, the Taj Mahal, all are landmark (literally) feats for the contemporary technology and societies.

    You comparing them with modern construction methods necessitated by capitalism, and with modern technology seems an unfair comparison, as well as circular reasoning.




  • My point is, if you read “aunt” as “landlord”, my comment is not about the landlords as much as the system.

    Without landlords, we’d not have a housing crisis. There would be enough housing for everyone, we have plenty of resources and land to build them. The US, not to mention the world, is still big enough for everyone to have their own plot of land and housing.

    How did people live before Capitalism? I’ve read that housing existed before even banking was invented. Somehow there wasn’t a housing crisis back then, until/unless we had exploitation.

    You’re not wrong in what you’re saying though. The basic difference of perspective between you and I, I believe, is that you’re viewing this from inside the capitalist system, where landlords do indeed provide a function. But if we’d not have capitalism, we’d still have housing, and with less value extraction/parasitism.

    As for the obscure anecdote, let’s instead use the simile of marketing. They add no value to you as a consumer, and if there weren’t so many marketers finding what you need would be easier and cheaper (as there would be no marketing cost). For the capitalist they add value, for the rest of us they’re an ever increasing drain on resources - a parasite.


  • I don’t know if I’m leftist, but the US spectrum is well right of most of the world.

    The question is multi-layered. Your aunt may or may not be a bad person, I don’t know her. Them renting out property may or may not be for good reason, even if they’re doing it to “survive” in the capitalistic economy.

    The real issue is that capitalism itself is exploitative, and (depending on where you draw the line) participating may fall under being complicit.

    My understanding of parasitism is extracting resources for their own benefit, with little to no benefit for the exploited/system.

    The first hint of parasitism is amassing resources they aren’t using for living. Your aunt and husband made surplus money to be able to afford buying the properties. Unless they did that by extracting resources, refining them, working them and making provisions for them to be recycled and ecologically compensated - others will have had to pay the cost. Either by working harder than them, or suffering more than them, for example due to an imbalance of ecology. This is one form of parasitism.

    Another perspective of parasitism is inserting themselves as a middle party. Your aunt almost certainly isn’t providing the housing at cost, where rent barely covers their labor and property upkeep. That means they are keeping someone from a home, unless they pay extra to your aunt. Just like a bully.

    Now, this doesn’t mean that your aunt has any malicious intent. The point is that the system itself is evil, like a pyramid scheme of bullies, where each layer extracts something from each underlying layer. This is useful for making ventures, but at the cost of ever increasing exploitation and misery. Especially when capitalists are allowed to avoid paying for restoring the exploited, or incentivised to do it more. I’m sure you’ve heard of enshittification.

    Now, example time!

    I’m sure you’ve thought that air is important for you to survive. And maybe you’ve ever worried that traffic or other pollution might make your air less good for you?

    Enter the capitalist! For a small premium we’ll offer your personalised air solution, a nifty little rebreather loaded with purified air you carry with you all day. The price is so reasonable as well, for only $1/day you can breathe your worries away!

    Now, producing the apparatus means mining and logging upstream of your town, removing natural air filtering and permanently damaging your environment, but they only charge for the machines and labor. Restoration is Future You’s problem. Selling and refilling the apparatus happens to also produce pollution, making the air worse for everyone. But that makes the apparatus more valuable! Price rises to $2/day.

    Competitors arrive, some more successful than others, all leaving ecological devastation and pollution that can’t be naturally filtered. Air gets worse. One brand rises to the top, air is more valuable and lack of competition makes it so that air is now $4/day.

    Then an unethical capitalist figures that if we just make the air slightly worse, profits will go up! They don’t want to be evil, but cutting corners when upgrading the production facility means the pollution gets worse. Other adjacent capitalists see that they also can pollute more without consequences. Air gets worse and price increases to 6$/day.

    Air is starting to get expensive, rebreather sharing services, one-use air bottles, and home purifyers crop up, increasing pollution and raising costs, air is now $8/day for most people.

    People start dying from poor air, new regulations on apparatus safety and mandatory insurance come up, driving prices further to $10/day. You now also need a spare apparatus and maintain it in case your main one breaks down.

    Etc.

    The point of the example is that through a series of innocuous steps, all making perfect sense within capitalism, you are now paying $300/month more to live than before capitalism, with little real benefit to you, and no real choice to opt out.

    Each and every step is parasiting on your life, by requiring you to work harder for that money, and/or suffer more due to pollution and ravaged environment.

    The only solution to not work/suffer into an early grave is to have others work on your behalf, perpetuating the parasitic pyramid scheme. This is where your aunt is, is she evil? Probably not. Is her being an active part of an evil system bad? Yes, yes it is. Capitalism bad.


  • Why can’t a complex number be described in a Banach-Tarsky space?

    In such a case the difference between any two complex numbers would be a distance. And sure, formally a distance would need be a scalar, but for most practical use anyone would understand a vector as a distance with a direction.

    They’re about as imaginary as numbers are in general.

    Complex numbers have real application in harmonics like electronics, acoustics, structural dynamics, damping, regulating systems, optronics, lasers, interferometry, etc.

    In all the above it’s used to express relative phase, depending on your need for precision you can see it as a time component. And time is definitely a direction.


  • Getting a cat to come to you is easy, you give it food and pets, and then stay calm when it’s eating/enjoying.

    Repeat until you’ve built trust, a sick or hurt cat will typically take longer to trust. Count on several days of repeating this without hitches (no sudden loud noise while you’re doing it, etc).

    Sometimes cats are desperate and everything turns up in a magical, calm way without bloodshed. But more commonly the next part is trickier, the cat will resist you picking it up (especially if hurt) or shutting it in.

    Trick here is to be decisive and clear in your body language. Prepare a cat carry box with hard sides, feel free to prepare it with some textile smelling of you, be mindful that it will almost certainly be pissed on. Also bring a towel.

    You will have to, in a calm manner, put the folded towel over the cat, and with it lift the cat into the carry. The towel is to trap legs so you won’t be scratched, and if you manage to have it snugly around the cat, there’s also a way to calm cats by gently pressing them down.

    If you are unsure, slow, nervous, or hesitate in your movement, the cat will bolt. If you’re too fast, loud, or big in movements, it will as well. Relax and do it in a deliberate motion.

    If you release the cat from the carry, it will take considerable time to rebuild trust. Consider either going with it to the vet at once, or let it out in a quiet spare room with food, water, and litter box, and giving it a day or three to get accustomed to the room before letting it explore the rest of the place.

    Don’t get scratched by the cat, they can have some pretty nasty stuff on the paws, and some transmittable pathogens if anything draws blood or gets in your face/eyes.

    Good luck!


  • Board games have been nearly ruined by kickstarter.

    Instead of buying a well reviewed and recommended game from a store, you have to back a hyped up sales pitch, and then wait 4 months for delivery, if the producers don’t just bail with your money or go “oops, we couldn’t finish what we promised, and we already spent all your money…”.

    And if you don’t back it to later read the reviews, the game is out of print and still waiting for the first wave of deliveries, meaning a second print is still at least a year off.

    Also, the ratings are heavily skewed by people rating on the hype or early/review copies, meaning the rankings are heavily amazonified.

    EtA: Also games are heavily bloated with social media candy: heavy and fragile minis, box stands, blingy crap periferals (branded dice holding toucan) and still needing organisers, player aids and mods from third parties who’ve gotten review copies to make said supplements…

    Oh, and the stretch goal extras (get another 150 vanity minis/3D printed scoring tokens) for only $150 and an 18 month wait!
