  • There's a new patch for revanced which spoofs the client to fix this issue. Unfortunately it's an optional patch that a lot of people miss, so they still have issues. I haven't run into the "play a little bit then lock up" issue since the patch released

  • The cap gains tax that the richest people in the world never end up paying?

    https://www.propublica.org/article/the-secret-irs-files-trove-of-never-before-seen-records-reveal-how-the-wealthiest-avoid-income-tax

    From 2014-2018 Warren Buffet alone grew his personal wealth by 24.3B, reported 125M in income (0.51% of wealth), and paid 23.7M in taxes (0.1% of wealth). Over 4 years, this man paid taxes on a tenth of a percent of his income. Similar tax numbers under 5% apply for other billionaires.

    The ultra rich never pay capital gains tax, loopholes allow them to have their income in portfolios, which isn't taxed. Capital gains is only for realized gains. When your portfolio is worth billions, you don't need to sell it to have spending money, you can take a loan against the value of portfolio.

    Capital gains tax only affects those who don't have a bank's worth of money in their portfolio.

  • Sorry, my notifications have been messed up because of the lemmy.world issues! Some other people have already answered but I'll still reply :)

    A heat pump's efficiency is measured differently than that of a gas furnace.

    The actual unit for heat pumps is the Coefficient of Performance (CoP). This measures the power input (electricity) VS the power output (heat). A "400% efficiency" as I put it, is a CoP of 4, meaning that for every watt of power used, 4 watts of heat energy are moved. As some other people pointed out, depending on the quality and technology of the heat pump and the interior/exterior temperature, the actual range of a heat pump is a CoP of anywhere from 2-5.5 (the theoretical, perfect maximum is 8.8). The efficiency of the heat pump does dip as the temperature of the region it's pulling heat energy from lowers, there's less energy available to move, so it has to work harder. This is why heat pumps in regions with especially cold winters have what's usually called "emergency heat" which brings us to...

    Electrical heating. This works by pushing electricity through a wire to heat it up. Directly turning electricity into heat. Electrical heating always has a CoP of 1 (terms and conditions apply). For each watt of electrical power consumed, 1 Watt of heat energy is produced.

    Finally we have gas heating, which is still the only option for some areas for various reasons. Gas heating efficiency is not measured with CoP but instead with Annual Fuel Utilization Efficiency, simply a number that represents what % of the fuel burned is actually turned into useful heat energy. I'm finding AFUE ranges of 76-97% as a general range for modern furnaces. If a furnace has an AFUE of 90%, that means that when it burns an amount of fuel representing 100 units of heat potential (I'm not using a unit, BTUs confuse and terrify me) then 90 of those units will be turned into usable heat, and 10 of them will be waste, whether that is heat that leaves via the chimney or is simply unburnt fuel.

    TLDR: 400% means 4x more energy is moved than is used, I apologize for the wordiness, I find this stuff rather interesting

  • Sorry my point wasn't that we shouldn't explore other options to use instead of/in tandem with A/C. I was entirely pointing out that the use of an AC/heatpump is by itself, in absence of the context of what is used to power it, a non issue as its one of the most efficient electric heating/cooling technologies we have.

    Wind catchers could be, and likely are a great technology to adapt for wider use, though I can't speak to that, I'm not an HVAC engineer.

  • I agree with you that we should be exploring alternatives, but aircon is extremely energy efficient for how much thermal energy it moves (reaching 400% efficiency in some cases) . The problem isn't aircon itself, but what is being used to power it (coal/natural gas power plants)

    In fact the technology behind aircon can be expanded into a heat pump to both heat and cool, being more efficient than electro-resistive or gas heating. There's even water heaters that will actually cool the area they're in and use the heat they gather from the space to heat the water.

    Technology Connections has a great series of videos that go in depth on both heat pumps and aircon.

  • You can still seed without port forwarding, not being able to port forward only affects how many clients can seed from you. Not being able to port forward causes it to be limited to only other people who are able to port forward.

  • No port forwarding ever set up on my system! It's bound to my interface and lockdown mode is enabled, all leeching and seeding is tunnelled fully.

    Edit: as far as I'm aware, not being able to port forward only limits who you can seed to. Meaning you can only seed to those who do have port forwarding.

  • Thank you for the correction! I agree it's far more accurate to call them authoritatian/autocratic regimes both now and then which is what I was trying to indicate by saying they were single party republics, but I suppose one should say what they mean and mean what they say.
