  • How much earth would compress and expand if all of it went from 0°C to 50°C

    Jump

  • The earth's core is about 5500C and is mostly composed of iron and nickel, probably. Presumably, it would shrink tremendously going from 5500C to 0C so in theory you could calculate the rate of shrinkage using iron's rate of thermal expansion. However the core is also under immense pressure which makes iron much denser (smaller) than on the surface of the earth. The immense temperature and pressure is a result of the action of gravity pulling the core onto itself.

    The short answer I think is the earth cannot exist as we know it at anything below its core temp of 5500. Suppose we waved a magical wand that set it's temperature to 0, it would implode on itself (along with the rest of the planet) and heat right back up to its current core temp of 5500 before you could measure the effects of thermal expansion.

  • How AI broke the smart home in 2025

    Jump

  • Society has been steadily forgetting the importance of reliability, all in the name of convenience. And in the end, you get neither.

    "They don't make it like they used to". Sure. Sure. Old man yelling at clouds. Blah blah. But when your light switches stop working because of some overly complex system that requires the switching data to travel twice around the world just to fucking turn a light on (or an AI to invent 15 Python scripts and a mathematical proof just to add two integers together), you've got a really fucking fragile system.

    And you know what isn't convenient? Fucking fragile products that break as soon as you touch them. Who the fuck wants a hammer made out of salami? Sure, it might look like a hammer, it might taste great, but it can't drive a nail for shit. That's a garbage product that belongs in the garbage.

    An LLM can tell me a (lame) joke. So can Bob. Bob can also turn on the lights, and is pretty good at that. But those things together don't automatically mean an LLM is good at turning on lights. They are fragile, by design, like the salami is!

    Stay in your fucking lane tech companies.

    The USA and Europe are now enemies

  • but suddenly there is very little that connects both continents.

    I think the Nazis would disagree with you.

    Communism, brown skin, religions other than Christianity are still public enemy number one.

  • Plastic bag bans are actually working, a new study suggests

    Jump

  • Anecdotally, it has made things worse. The shopping bags were already being reused as garbage bags, now I have to buy rolls of single use plastic bags instead. Worse, those tote bags are everywhere now, and so much less ecological.

  • ELI5 why I logically understand McDonald's food is low quality and bad for me but I crave it like crack?

    Jump

  • You crave salt and fat because your body needs a little bit of these things to survive, but finding salt and fat out in nature is really really hard, so those cavemen that liked the taste of salty or fatty foods enough to make the extra effort to find those foods were more likely to survive to be your ancestors and you inherited that behaviour. That's why you like McDonald's, it's full of the salt and fat that is hard to obtain if your diet consists of mostly roots and mushrooms and leaves.

    McDonalds is bad for you because it's unnaturally full of salt and fat. Far, far more than your body needs and far more than your cavemen ancestors would have eaten naturally. Especially if you eat McDonald's often. Too much of anything turns that thing into a poison.

    McDonald's has only been around a generation or two. That's not enough time for the people who crave McDonalds and eat too much of it to die off, leaving mostly people who don't crave McDonalds to remain.

  • The Enshittification of Plex Is Kicking Off, Starting with Free Roku Users

    Jump

  • Enshitification is the specific process of capturing a supplier/consumer market through short term subsidies, squeezing out the competition, and then squeezing the suppliers and consumers directly.

    Increasing prices alone isn't enshitification. But increasing prices after sustaining artificially low prices for the purpose of creating a monopoly or quasi monopoly is enshitification.

    Plex most definitely was providing a good quality product but was not generating revenue, and has little to no competition (Jellyfin is a bit debatable) as a result. Was it intentional or just incompetence? Hard to prove either way. I'd say the biggest argument against enshitification is that Plex is mostly a product instead of market space hosting suppliers and consumers, like Google, YouTube, AirBNB, Uber, etc.

  • I'm not sure why the author chose this sentence and why you are picking it out. The author provided no evidence of it. Instead, when you read on it seems to be an ownership problem. People rotating in and out for a year on a ten year project. You can be the most competent and skilled worker, if you don't get the opportunity to become invested in the success of a project, of course you won't see the project become successful.

  • I love Linux. I use it wherever I can. I don't use Linux on my primary gaming workstation, for the simple reason that the display drivers, specifically mixed extended desktop and screen mirroring is just straight up ass.

  • Trump Administration Eyes 50-Year Mortgage Plan Amid Housing Crisis — But Not Everyone's on Board

    Jump

  • The amortization length affects proportion of principle paid down, but it doesn't eliminate it entirely. At the same interest rate, you end up having paid more in interest at maturity of a longer amortization, yes. In practice, this can be mostly mitigated by negotiating a lower rate, or negotiating and exercising prepayment privileges.

    More importantly, with a mortgage, ownership of the property is yours entirely, from day one, not the lenders'. What you owe is cash, not the property. The property is merely collateral in the event of default of payment.

    BTW, multi generational loan agreements are not new. They are somewhat common historically and in other places of the world. For the same reason that multigenerational housing is the historical norm.

  • The tragic change a single year has made in America

    Jump

  • Yes and no. A lot of people are misinformed. It's easy to say not being misinformed is the responsibility of the individual, just like recycling plastic is the responsibility of the individual consumer. Reality is a bit more nuanced. Misinformed people often simply don't have access to good information or critical thinking skills to not be duped. Many others are straight up vulnerable to manipulation, through fears etc.

    Democracy only works if people are informed. I think the American system has failed catastrophically to inform ordinary people.

  • The GOP expected Democrats to relent on the shutdown by now. That isn't happening.

    Jump

  • Governments are the product of the people. There is no divine or natural laws that triggers "an election". A government is simply created from thin air when a group of people (any group of people) get together and say: fuck the old system, we are putting that in the trash and signing a new social contract.

    Of course, there's virtually never unanimity of agreement over this social contract in one geographic area, so that social contract is only as binding as the force used to put it in effect.

    Realistically, 6 months+ of government shutdown in the US will likely cause a collapse of the USA as a single unified federal entity, since the federal government effectively rots. At that point, all bets are off. A fracture of the US is very possible.

  • Historians never talk about the "good old days".

    Jump

  • Broadly speaking this is probably true. In a smaller context, though, there are tons of counter examples. The internet for example, from just 10 years ago, was unquestionably better. AI slop, bots, enshitification, social media and browser monoculture...

    The anti science trend of MAGA over the last few years...

    Etc. Regression does happen, and we should not take things for granted.

  • New Rules Could Force Tesla to Redesign Its Door Handles. That’s Harder Than It Sounds

    Jump

  • I hear they are a solution to the problem of increasing mileage/efficiency. I am no fan of Tesla, but we have to admit, there is some merit to that argument, however debatable the efficiency benefits are.

    That's not to say safety isn't a serious issue. The biggest problem is the reliance on electronics. Now if someone can reinvent the design with a highly reliable mechanical system, with multiple redundancy.
