Insulation's role in overheating a 'myth' - building experts
  • It's all about the short term, this reminds me of the time that Mike Hosting said that petrol engines are simple when comparing to electric motors.

    Just completely uninformed!

  • If Clinton, Trump, and Did Not Vote were presidential candidates in 2016
  • In New Zealand we have a "voting day" which is a Saturday, but you can vote before the day, there is no restriction. You can vote for a week before the election.

    The last two elections, I cast an early vote because it fit better with my schedule.

  • If Clinton, Trump, and Did Not Vote were presidential candidates in 2016
  • Not really, did not vote is exactly the same as voted for the winner. In a FPTP not voting is saying whoever wins, that's what I wanted.

  • Legal risk and more paperwork: do health and safety laws threaten the great Kiwi school trip?
  • Whilst this is true, the reality is that this is a race to the top. If one school finds that it is reasonably practicable to do an action, then this is the new industry standard.

    If you have worked in the industrial world, this happens, the law says X but industry best practice goes beyond the law; which it often does (the law is slow) then if there is an incident and you "only" follow the law this is not looked at kindly.

    This unfortunately, means the schools with the most resources get to set the standards.

  • theconversation.com Legal risk and more paperwork: do health and safety laws threaten the great Kiwi school trip?

    New research shows high levels of teacher anxiety and frustration over legal liability and paperwork for school trips. But there are ways to maintain this crucial part of the curriculum.

    Legal risk and more paperwork: do health and safety laws threaten the great Kiwi school trip?

    I'd hate to see the school trips decline.

  • Yes this is probably true, but what will end up happening is that we will continue to buy houses off each other at ever inflated costs. Only the bankers will win.

    Investment into productive assets is just not the NZ way.

  • Pornhub Pulls Out of Nebraska
  • Exactly. There are some things that kiwis are just not good at, we have to get imports for some jobs.

  • Pornhub Pulls Out of Nebraska
  • SHHHHHH!!!!

    We don't need more people, we have enough of a housing crisis as it is.

  • Donald Trump says he 'took a bullet for democracy'
  • Called it.

    I said to my co-workers as soon as I heard he got shot at, he was going to claim that he took a bullet for America and Democracy.

    But it wasn't exactly hard to call it....the guy is a major narcissist.

  • What would a 3 hour work day be like?
  • Agreed, but crossing over on Wed would work out for changes.

  • Thank you!

    This is how the internet should work.

  • Follow me for more deep political analysis
  • Expect rather than names, just put down a list of head line policies.

  • Follow me for more deep political analysis
  • How?

    I'm in NZ, we have a whole bunch of politicians to choose from, and it always comes down to who is the least likely to fuck things up beyond repair. It is not often that an objectively good candidate, everyone has their flaws.

    In this example the question is not is Harris an objectively good candidate, but is she objectively better than Trump?

    In my opinion yes, yes she is! Trump is the worst, the way he has emboldened the far right world wide is truly terrible.

  • What would a 3 hour work day be like?
  • 3 hours a day wouldn't be that useful. You still have to "be" somewhere 5 days a week.

    What is useful; I did this for a few years; 3 x 8hr days. Mon - Wed, normal work hours, and a 4 day weekend. No need for "public holidays" even paid time off becomes less relevant, when you can switch one week to Wed - Fri. Leaving Thur - Tue as a "normal" way to take time off, giving a 6 day weekend possible every second week.

  • What scientific discovery, which could actually happen in the next 5 years, would have the most impact in our lives in you opinion?
  • High temperature superconductors.

    Specifically anything above commercial / household freezer (-18C); but if we could get to ~105C (above water boiling) it would change literally everything.

    Electric motors become more efficient over a much greater RPM range.
    Superconducting magnets become much easier to construct and run, this gives us a much better chance at fusion.
    Transmission lines themselves are pretty efficient as it is, but all of the associated switchgear at the conversion points all gets really warm, this could be virtually eliminated.
    The conductors on circuit boards, and potentially inside microchips. This reduces heat loading and thus makes all computing devices more efficient.
    The conductors in batteries; enabling these to be smaller and thus increasing battery energy density.
    Finally making super-capacitors actually viable as longer term energy storage.

    There are so many aspects of life that would be impacted by this one breakthrough, that it is probably the most important thing that will happen this century (scientifically speaking). It would be almost as revolutionary as when electricity itself became widespread.

  • What scientific discovery, which could actually happen in the next 5 years, would have the most impact in our lives in you opinion?
  • Nuclear Fusion and "net zero emissions" doesn't really make sense.

    What I think you are trying to say is that fusion is nearing the point where net energy is possible (that is getting more energy out then the amount of energy put in to create the reactions in the first place). Fusion is not practically close yet, but there are tantalizing hints that we are close.

    See this from 2022; the national ignition facility produced more energy that was impacted on the target (2MJ in 3MJ out), but this doesn't take into account the huge inefficiencies in the laser generators to produce that 2MJ laser pulse.

    There are a bunch of fusion experiments that are hitting massive temperatures (120 - 150MK) which is starting to get into the range where practical fusion could occur, the center of the sun is approx 15MK but also has massive gravity to encourage fusion.

    So fusion is still a decade away at least, but we understand the science much more completely now. We know the problems (well a bunch of them) and it is mostly now a very difficult engineering problem rather a problem of understanding the science.

    YSK there is a massive Google Doc of U.S. gynecologists that will tie your tubes without asking about your kids, marital status or age.
  • It is not an unreasonable question, I was asked the same when I got my vasectomy. The implication was "you are young enough to have another should the worst happen", not that kids are replaceable parts.

  • Capitalism and fascism
  • Generational shifts happen slowly and in full view. You can act accordingly, this is a process that lasts decades.

    COVID happened in months, spread like wildfire and put a huge strain on healthcare systems worldwide. No amount of money thrown at the system would have increased capacity.

  • Capitalism and fascism
  • What would count as real proof, if not prices falling due to competition?

    That is the problem I was referring to in my original post, "economics is a very murky science", I come from an engineering and physical sciences point of view. Good economic data is hard to come by, it is always contaminated with chaotic factors that cannot be controlled for. "Proof" may not be possible in economic science.

    Why would it not be true?

    Because from a logical point of view, there is no necessity to go from socialism to communism. A country could easily decide that socialism is where they wan to stay. When something is necessarily true, not only does it always happen it must happen. That is the point I was trying to make, there is nothing fundamental about socialism forcing that transition from socialism to communism.

    Again, this has nothing to do with Socialism or Communism.

    I have to disagree with you there, in a capitalist system the burden of care falls on the individual (see the American health care system), whereas in socialism and communism, that burden falls on the state. This is a key economic factor, I'm from NZ and the social healthcare system is really awesome, but as with everything we can see how it could be better.

    The system has a capacity, if you want to increase that capacity you have to have the resources to do that. If your population is not growing (stable is not enough) then your health care system is always in danger of not having enough resource. The problem is that the system always need to grow, as we get better at improving the lives of people and increasing lifespan the burden from the elderly increases. The resources used to care for the elderly are finite and use up system capacity.

    Even in a capitalist society the system has capacity limits, there is no amount of money that you can throw at it to increase your number of doctors tomorrow. You have X doctors today, this is not easily increased beyond the natural rate (X+new doctors-retiring doctors), all you can do is move the existing ones around.

    You can use this argument for a lot of major points of expenditure; education, welfare, transport etc....but healthcare is starkly different between the different economic models.

  • Capitalism and fascism
  • While I appreciate that Marx made a case, this is not data or evidence. It seems intuitively true, but that doesn't really move you closer to real proof.

    Essentially, competition forces prices lower, and automation and increased production lower the price floor. Automation is pursued because it temporarily allows you to outcompete, until other firms can produce at the same price, forcing prices to match at a new floor. This continues.

    I'm not sure if you are trying to imply automation is a good or bad thing. Looking through history, the industrial revolution was bad for the workers of the time, but in the long run massively improved the living standards of everyone. Automation is a net good in my opinion. Competition is simply an accelerator, this is not really tied to the economic system being used. In capitalist or communist systems, firms that are protected from competition (by what ever means) do not innovate as fast or as effectively (see Intel as a great example of this).

    Socialism is just the precursor to Communism.

    While this can be true, it is not necessarily true.

    I don’t see what birth rates have to do with anything.

    As your population ages, the costs to care for them raise at an increasing rate. If you don't have enough new workers to stabilize the economic base, the burden that an aging population places on the younger generation grows until it becomes untenable.

    Casey Costello's order to halve the tax is "something that tobacco companies would have been keen to see," an expert says.

    Not sure if this is a good thing or not.

    HTP's may help stop smoking, or just as likely (in my opinion) increase the rate of people starting.

    Seems like a win for the tobacco industry either way.

    Sleight of hand in combat

    I am running a Tabaxi rogue that is currently 4th level.

    In a recent fight, purely to piss off the leader of a band of thugs, my character ran in the 20ft and lifted his gold pouch (lucky roll 19, for a total of 26), then proceeded to bonus action disengage. The feline agility racial ability allows me to double speed for a round, so was able to disengage to a distance of 40ft.

    The DM was totally ok with this, I didn't actually do any damage and I "wasted" my turn for flavor and fun.

    I get that you can't use slight of hand to perform a disarm, but what is are your thoughts on lifting daggers/arrows/spell components etc....which are not being held by an enemy?

    This could be very OP if I'm allowed to steal a wizards components pouch, rendering them significantly less of a threat.
