  • Also windows locks files that are in use, so attempting to delete system32 would (probably, I’ve never tried it) give some errors because it’s using a bunch of those files already and would leave those files intact even if you’re very determined to get rid of them. This is why you need to reboot to apply many updates because even the updater can’t get around that restriction.

    It’s handled differently on Linux. I’m not 100% on the specifics of the implementation but it either loads files in use entirely into RAM or simply removes the reference to the file when deleted (or makes a new file and points the reference there if you’re replacing the file). That means anything that is currently using the file can continue to do so after a delete/overwrite, so the OS doesn’t prevent it from happening. This is why you can run any updates without restarting on Linux (though you do need to restart to get the system to use some updates, if they update critical components that can’t be restarted independently of the rest of the system, like the kernel).

    If you want to nuke your whole os install drive on windows, you need to boot into a different OS instance (which is what the repair partition is, just a barebones windows install that can access files on the main install without the locking). But Linux can do it from within the same instance.


  • Don’t get me wrong, it’s decent entertainment. It’s just disconnected from any kind of scientific or technical reality and a part of me is rolling my eyes for a lot of it. And maybe a bit frustrated because I like thinking about things and analyzing and problem solving. I prefer hard magic systems over soft magic ones because there’s no point in thinking about soft magic systems because they just do whatever the plot calls for when it calls for it while hard magic systems have to build up to it and need to be clever to surprise viewers.

    Tony uses a soft technology system that defies thought.


  • Yeah, Tony was capable of doing whatever the writers wrote him to be capable of, just like every other fictional character. And the writers wrote him doing it in a manner similar to the “programming” in Swordfish or the tech work in NCIS (or whatever show it was that had multiple people typing on one keyboard at the same time). As in difficult to tell if they had any understanding of it at all, sensationalised it for entertainment purposes, deliberately made it unlike any real programming to troll people who do understand programming, or some combination of all those.

    MCU science might as well just be another school of magic. Especially when Tony’s suit could shapeshift and convert between matter and energy because of some quantum mumbo jumbo. He just cast a quantum spell on it.

    Also every movie had multiple impacts in that iron suit that should have been worse for him than most car crashes.






  • A big historic example of this was back in the middle ages, when people didn’t have any idea about how to determine true from false when there were two conflicting views, they’d do a trial by combat because if you were right, how could you lose a fight specifically meant to determine if you were right?

    Though exceptionalism does come into play because those who believe it about others seem to think something different is going on when they are the ones suffering. Like maybe it’s a test rather than a punishment, or there’s some complex plan that involves a period of suffering or something like that rather than just accepting that sometimes life isn’t fair.

    Society should be all about trying to offset that unfairness, especially in areas like food, housing, healthcare, and (some) things typically covered by insurance.




  • Though even in that case, the people in the class where the material wasn’t taught properly get a pass without necessarily understanding that material. On the one hand, it’s not fair for them to be punished for the prof’s mistake, but on the other hand, it’s not necessarily a good thing to give them credit for something they don’t know. It could hurt the credibility of the degree itself, similarly to the ones where you’ll get the diploma as long as you pay the bills.

    People who hire the free pass people see they lack the skills despite having the paper saying they have them and stop hiring people with those credentials. It’s the same reason why cheating is dealt with so harshly.

    The skills and knowledge are the whole point, not getting high marks or everything being fair. That said, it would be a difficult situation to deal with because being fair should still be a part of the equation, I just disagree about it being the most important part.

    Another scenario for changing the rubric would be if the people running the course realized that something they thought was important for determining competence was actually trivial. This one could also be complex to handle fairly.



  • We don’t absorb everything completely, so some passes through unabsorbed. Some are passed via bile or mucous production, like manganese, copper, and zinc. Others are passed via urine. Some are passed via sweat. Selenium, when experiencing selenium toxicity, will even pass through your breath.

    Other than the last one, most of those eventually end up going down the drain, either in the toilet, down the shower drain, or when we do our laundry. Though some portion ends up as dust.

    And to be thorough, there’s also bleeding as a pathway to losing nutrients, as well as injuries (or surgeries) involving losing flesh, tears, spit/boogers, hair loss, lactation, finger nail and skin loss, reproductive fluids, blistering, and mensturation. And corpse disposal, though the amount of nutrients we shed throughout our lives dwarfs what’s left at the end.

    I think each one of those are ones that, due to our way of life and how it’s changed since our hunter gatherer days, less of it ends up back in the nutrient cycle.

    But I was mistaken to put the emphasis on shit and it was an interesting dive to understand that better. Thanks for challenging that :)


  • Even if the soil is preserved, we’ve been mining the micronutrients from it and generally only replacing the 3 main macros for centuries. It’s one of the reasons why mass produced produce doesn’t taste as good as home grown or wild food. Nutritional value keeps going down because each time food is harvested and shipped away to be consumed and then shat out into a septic tank or waste processing facility, it doesn’t end up back in the soil as a part of nutrient cycles like it did when everything was wilder. Similar story for meat eating nutrients in a pasture.

    Insects did contribute to the cycle, since they still shit and die everywhere, but their numbers are dropping rapidly, too.

    At some point, I think we’re going to have to mine the sea floor for nutrients and ship that to farms for any food to be more nutritious than junk food. Salmon farms set up in ways that block wild salmon from making it back inland doesn’t help balance out all of the nutrients that get washed out to sea all the time, too.

    It’s like humanity is specifically trying to speedrun extiction by ignoring and taking for granted how things work that we depend on.


  • Not to mention that even when some components do shrink, it’s not uniform for all components on the chip, so they can’t just do 1:1 layout shrinks like in the past, but pretty much need to start the physical design portion all over with a new layout and timings (which then cascade out into many other required changes).

    Porting to a new process node (even at the same foundry company) isn’t quite as much work as a new project, but it’s close.

    Same thing applies to changing to a new foundry company, for all of those wondering why chip designers don’t just switch some production from TSMC to Samsung or Intel since TSMC’s production is sold out. It’s almost as much work as just making a new chip, plus performance and efficiency would be very different depending in where the chip was made.
