  • There’s a whooopoooole lot of factors that can be involved, and it can be a combination of all of them.

    Background: microwaves don’t just heat water, they heat things with molecules that, like water, have a lopsided electric charge. When the microwave energy comes in contact with something, it either goes through it without interacting, bounces off of it, or is absorbed. Light with a window, a mirror and black paint is the same.
    Lopsided molecules absorb the microwave and wiggle, and wiggly molecules are what we perceive as hot.
    Microwave safe items are transparent to the microwave energy, and it goes through to the food.

    Depending on the material your plate or bowl is made of, it might not be properly microwave safe. Some ceramics have the lopsided molecules microwaves like, so they get hot.
    The bowl might also be made of a material that transfers heat really well. Think about how air from a hot oven is tolerable to have hit your face but significantly colder water is lethal.
    It’s in continuous contact with something that’s getting up to boiling, the steam on the food, and so it gets hot quickly and transfers the heat to your hand easily. Since water can absorb a ton of energy before turning to steam, the energy is there for a while and there’s plenty to heat the bowl.
    Finally, microwaves have hotspots, even with the rotating tray. This can work with either of the previous two things to allow the food to stay cold while pumping a lot of energy into the bowl or one spot in the food. It’s why a lot of reheat functions run the microwave and then sit for a few minutes:it lets the heat from the hotspots even out.



  • My point was more that the corporate behavior is geared towards pleasing fund managers rather than retirees or people with retirement accounts.
    The fund manager decides where the money goes, so they’re the ones that need to be happy. Yes, legally both the fund manager and the company have a fiduciary duty to the literally millions of people with 401ks that put money into their stock or fund, but in practice it’s fund managers who matter.
    If blackrock says that all things being equal, they’re going to preferentially invest in sustainable companies, suddenly companies have an incentive to make themselves sustainable by whatever metric blackrock is using. Likewise when an investment firm doesn’t reduce their stake in an insurance company for harming patient outcomes.

    Non-voting means the CEO can be sued by them, but not replaced. It’s a different level of responsibility.


  • I would disagree that that is an example of generational warfare.
    The older people get, the less of their money tends to be in actual stocks, and the shares managed by retirement funds are inevitably non-voting, so they can’t even voice what tiny bit of opinion their fraction of ownership would theoretically get them.

    The “shareholders” being performed for are the managers of those investment funds.
    Making obscene wealth on stock investing is relatively rare, but making obscene wealth investing other people’s money and then paying yourself an obscene salary out of the proceeds is far more common.
    Those are the people who control the massive amounts of money that companies perform for to drive up share prices.

    Why own when you can get paid to control? Then your money isn’t on the line and you don’t need to be lucky to get rich.








  • Accessing that location data isn’t trivial. The data is typically held by various private companies who put up at least token legal resistance to cover themselves from lawsuits.
    Intelligence agencies have their own avenue for getting the data, and on paper they’re not allowed to share it with police agencies.
    Police agencies typically need to specify the individual in question, or the specific location and time to get a warrant. This is because they’re not supposed to be able to blanket surveil an otherwise private piece of information without having a good reason.
    The classic example is not being able to listen to every call on a payphone they know drug dealers use because they’ll listen to people who have not done anything illegal.
    Intelligence agencies are an entirely different thing with weird special rules and minimal and strange oversight.

    This is all relevant because the government doesn’t actually know who’s allowed to be here or not.
    Most people in the country without proper documentation entered legally and then just stayed outside the terms of their entry. The terms can be difficult to verify remotely, which is why you’re not actually here illegally until you go in front of a judge, they deport you, and then you return again.

    Finally, there are significant chunks of the country where location tracking via cell tower is imprecise enough to get the country wrong, and a lot of people live there. So any dragnet surveillance setup is going to have to exclude some pretty large population centers to avoid constantly investigating people in Windsor sometimes quickly teleporting into Detroit.



  • EMP works a little different. It doesn’t emit energy in a frequency in the sense that WiFi uses a frequency.
    A changing electric field creates a magnetic field, and a changing magnetic field creates an electrical field. An electrical field makes charged particles move, and electrons move very easily in metal wire, so we get measurable current flow. This is ultimately the principle behind how generators work.

    What an EMP does is basically turn any conductive material it hits into part of a very short lived generator. The bigger the conductor, the bigger the current. If something is big enough, it can generate enough current to damage itself, depending on how big or fragile it is.

    A lot of small electronics have antenna, but they’re very small, so they don’t generate much current. If that current would be enough to overcome the voltage protection the devices have to protect against the voltage surge from nearby lightning or the like is beyond me.


  • We actually have extensive electrical backups for almost all of those things. The landline phone system was built in an era where people were significantly more concerned with nuclear war than we are now, so it would fare pretty well.
    Home Internet would be down, but the actual data centers all have multiple backups for power.
    The cell system would kick most people off, but it also has a lot of backup power built into it because it’s viewed as an important part of disaster response in the modern world. Part of the reason it sheds load is to keep capacity available for emergency response.

    Don’t get me wrong, it would be super bad, more disruptive than a typical or even atypical power outage, and last a long time, but it wouldn’t irreversibly take out civilization.

    Tldr it’s still definitely bad, but it’s not the irreversible one-shot to a continent and the climate that it was made out to be.
    Electrical and communications systems are built to tolerate natural phenomenon that have marked similarities to EMP, so while the EMP would definitely knock out power in the most impacted areas and to a great extent in more outlying areas, major components would be able to be brought back online in a timely fashion, and backup systems would remain available for key portions of infrastructure, such as battery and diesel generators to keep emergency communication systems online.

    Communication infrastructure is particularly sensitive to EMP, but as a result it’s been insulated due to practical necessity against environmental sources, as well as as a deliberate defense against EMP, since we’ve known about the risks for decades.

    EMP does damage proportional to the size of the conductor it’s attached to, since it causes current to flow, and the more there is, the more current flows. That’s why power lines generate massive currents, and small things don’t.
    A cell phone has a very small antenna, so while it’s fragile it’s not getting hit as hard and can potentially just be disrupted but not physically damaged.
    Computers are sensitive to single digit voltage fluctuations, but their parts aren’t big enough to generate enough current to burn anything, and the source of the biggest current, the power grid, is already insulated from the sensitive parts because the grid regularly has fluctuations that could cause disruptions, and can be reasonably predicted to have potentially damaging fluctuations often enough to warrant components that burn out in a controlled fashion to protect expensive things.

    Damage would be severe, widespread, and variously protracted. Not a quick trip back to the 1800s though. More like the great blackout of 2003, but with a bit more fire.


  • a single nuke in orbit would emp a whole continent and destabilize climate

    That’s a bit overblown.

    https://en.wikipedia.org/wiki/Starfish_Prime

    We’ve done orbital tests before and while the effects are more than we expected, they are not continent crippling or climate destabilizing.

    about 900 miles (1,450 km) away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms, and damaging a telephone company microwave link. The EMP damage to the microwave link shut down telephone calls from Kauai to the other Hawaiian Islands.

    It’s definitely not good, and there’s a reason we all agreed not to do that anymore, but it’s really more about the damage it does to satellites that hurts everyone, and the damage being too unstructured to be worth investigating too far.



  • NAS. Most things sit in downloads indefinitely, and I’ll randomly decide the folder is gross and unmanageable and put things into appropriate folders. Usually Documents gets the most sub-categories, with various significant life docs sorted by category and year. Pictures gets random art I made in a folder, pictures, memes and funny shit, etc also get their own folders.

    Media downloads go straight to the NAS where they’re organized by Format/Category/Series/Name. As in Video/Movies/John wick/John wick 1. TV gets a season level in there.


  • Check engine light? That’s fine, if it goes wrong it’s just him. The high beams are dangerous, inconsiderate and just a dick move, but also something that could be done by mistake.

    Flagrantly violating traffic control signs is dangerous to him, anyone in his vehicle, other drivers, and random passerbys. That’s a pretty big no-no, and worth reporting in the harshest terms on its own.

    Would you have wanted previous riders to have reported that behavior before you got in the car? If you knew they were going to drive like that would you still have picked them as a driver?
    If not, why would you let someone else be in the same situation you would take steps to avoid?
