    No, that's a safety feature. It's like saying that behind every fire there's an architect that installed fire alarms for this very occasion. Without red LEDs, people will have no way to know the robot turned evil.

    The funny thing about RF work is how casually a few orders of magnitudes gets thrown around. 10 dB fudge factors for assorted losses are quite common.

    I guess you could look at governmental budget or number of employees, but raw size is quite a bad metric for overreach. The knowledge that one year a lot of money was spent inforcing laws tells you very little about the effects that has on the population as a whole.

    To do that you'd need a good definition of what exactly overreach is, and you'd probably have to do a lot of work because I doubt anyone else had the exactl same definition.

    I'm assuming there is a lot of regional variation here, the wasps near my house have never caused much trouble, they just eat dead mice and large grasshoppers. One even let me pet it recently. We did end up nuking a nest inside the garden hose box a few years back, but I doubt the wasps chose a problematic location intentionally.

    I mostly see tankies as an authoritarian (far right?) group pretending to be far left. Or at least that's how they brand it, even though they openly advocate for government confiscation of all property.

    All the tankie (far "left") shit. It's all either bad faith arguments (trolling), blatant propaganda or people who never bothered to fact check the propaganda.

    They also create an inordinate amount of communities, had to use the "block instance" button a lot.

    NSFW stuff also gets annoying after a while, but that seems less prevalent. (Just had to block one instance to get 99%)

    Looking at my block list, the AI images and niece music stuff also got added at some point.

    Computers can really just do two things: copy data and do math. Anytime your your doing anything but copying data verbatim, there is math involved. Anytime your reformating, filtering or acting on data their will be some math involved.

    Take displaying an image: you can't just copy image data to the screen, because it could have a different resolution, or color space, or be compressed. In all of those cases, you will need to do a lot of math to get things to work right.

    The exact math varies, in graphics, CAD or geospatial stuff, expect a lot of geometry. Any sort of statistics or classifier is going to involve a lot of linear algebra. Even simply storing data in s quickly accessable manner involves quite a bit of math.

    Does your car lock up outside of cell coverage? I'm not suggesting removing the radios themselves, just the antennas. To the car, it will just always be out of range.

    The antenna used for talking to the keys might cause trouble, but those are either inherently short range inductive systems or are receivable using a 20$ RTL SDR to verify it's not sending anything else.

    Should be quite easy to remove any WiFi/cellular/satellite antennas from the car's computer. (Might be trace/chip antennas, so make sure to get those). If you're extra paranoid, get the GPS antenna too, so it can't simply record data indefinitely.

    Might take a few hours to go through the car to make sure you get everything, but you won't be limited to super old cars.

    4000 years ago humans were farming, living in cities and just starting to figure out writing.

    Given how nicely centered the impression is, this was probably intentional, a very old foot selfie.

    Graphite is normally very soft and slippery, and is even able to act as a dry lubricant when finely powdered, however many sources claim that graphite powder can be highly abrasive, to the point of potentially destroying milling machines. Does anyone know how such a soft material can abrade metals?

    A simulation based on maxwell’s equations and ohms law of a very long circuit, demonstrating how current can *seem* to travel faster then light. This is actually the exact same effect as the characteristic impedance of a transmission line, while pulse is traveling down it, the transmission line will appere to have a particular impedance, regardless of what is on the other end.

    I am not familiar with the legal situation this instance's server and owner is in, are there any actions a user could take that could expose the operators to legal liability? Could the instance face problems if someone posts a link to pirated content? What about general discussion of piracy? Or any other possibly legally problematic content?

    Not exactly useful as the simulation is 2d, but cool.
