  • What the hell even is the point mandating a back up alarm for self driving cars ? Backup alarms literally only exist because visibility to the rear is worse, and to warn pedestrians that a vehicle nearby is moving with very poor to no visibility, but that only applies to human operated vehicles. Autonomous vehicles use 360° sensors, they can “see” just as well in reverse as in forward. Be that good or bad, it’s equal in every direction, so mandating an alarm just for reverse seems enormously pointless. Especially since the cars tend to be slower in reverse, so if anything it’s less necessary then, vs. when they’re moving forward.



  • Nominally you can use it to plug a generators output into a household circuit, which will provide power to that circuit in cases of a blackout, saving you from needing to unplug everything critical and daisy chain 10 multiplugs to the generator.

    It could also be used to connect two seperate household circuits together, if only of them is actually live for whatever reason.

    In reality you shouldn’t his at all, ever. Just daisy chain the extension cords. If you forgot to isolate the circuit by flipping the main breaker (easy to do if there’s no power anyway, because of a blackout), and then the grid comes back on, your generator is gonna have a real bad time. And then there’s obviosuly the electric shock risk of using something like this.




  • Not to necessarily defend the idea in the article, but that comment screams that you just read the headline and not the article.

    If you had read the article, you would know that the author doesn’t want to get rid of routable addresses, they want to replace the current system of IP address assignments with an automated cryptographic address system, allowing network size to rapidly increase, and self organise without reliance on a central address authority. So your analogy of having no address at all is massive misrepresentation of the authors idea.

    Wildly misrepresentating ideas is never good. Even if you dislike it, by wildly misrepresentating the idea, it just discredits your own stance, because it’s (seemingly) based on falsehoods.

    Pretending like the author just wants to just abolish all types of routing addresses is dishonest.



  • Yes. And the fathers are equally capable of saying no. And the men themselves are equally capable of not being cunts.

    There’s 3 people involved here, 2 of which are men, and this guy specifically singles out the the one woman, and blames her. That’s sexist and mysoginstic.

    “When women are bad, it’s their fault. When men are bad, it’s their mother’s fault” is an objectively sexist and shitty stance to have.

    If you wanna blame the parents, blame BOTH. Singling out the mother is mysoginstic.

    I mean, that’s better than selling to a private person, still feels weird, since disclaiming a patent is absolutely possible, and has a 100% chance of leading to the desired outcome, vs whatever small chance there may be that the University starts taking profits on it. Or even just sees themselves forced to sell the patent, because of potential financial issues.

    Yeah, the risk is small, but eliminating it in it’s entirety would’ve been easily possible, so it just feels a bit weird he didn’t do it.



  • Führer might only mean leader in Germany, but it’s rarely used outside of refering to Hitler nowadays.

    Leader, in modern German, would be translated as “Anführer”, not “Führer” specifically because of the connotations. Also, using the term fuhrer in English, instead of translating as leader, clearly means it’s being used as a title, rather than a factual descriptor of what he was.

    You can use Führer in context, but as it’s a title that was specifically created by and for Hitler, and never used before or since, it’s generally not used as a title for him, because people don’t want to give him the post mortem respect of addressing him by this title.

    And for context, the entire German language Wikipedia entry of Hitler, calls Hitler Führer a total of 17 times. 8 of those are in direct quotes, 3 in indirect quotes, 2 of them are describing his official title “Führer und Reichsanzler” (outside of quotes only, to prevent double counting), 2 use the literal meaning of “leader” in the context of the party, NOT his title as dictator, 2 of them are talking about how he saw himself, and one is drawing a linguistic analogous link between “Führer” and “Geführten” (Leader and Followers).

    Outside of quotes, there is not a single use of the term “Der Führer” as an actual honorific title (“The Führer”) for Hitler in the entire German language Wikipedia page (which is 30-40k words long).

    Weighing the benefits of an action vs its effort is a bizzare way to look at things for you ? Interesting stance to have, I’m curious how you decide if something is worth it or not.

    And the goal of my comment was obviously not to make or save money, so that’s a shit comparison. If you take an action with the explicit and singular goal of saving money, I do think it’s absolutely worth it to consider if you even save enough money to be worth the bother. Yes switching on and off an outlet is only a tiny effort, but you’re literally doing it JUST to save money, and the amount of money you save is EVEN MORE tiny and miniscule.



  • a 110/220 auto sensing plug

    There’s no real need for a plug to be able to sense what voltage it’s plugged into. That would be handled device side, not plug side. And for devices for which handling both 110 and 220 makes sense, well those pretty much universally already have a switch mode power supply that does so automatically, or at least a dip switch with which a user can manually select their grid voltage (check your phone or laptop charger, I can virtually guarantee it already supports both).

    And the issue with devices that don’t already do this, is generally that they are basic resistive or inductive loads (anything along the lines of heaters or motors), with little to nothing in the way of digital control electronics, which need to be designed for a specific input voltage in order to achieve a specific power output. Making these devices both 110V and 220V compatible would require either giving every single one of them a voltage transformer, or to include a 110V motor/heating coil, and a 220V one, that can be switched between. Both of which would massively increase the price of these devices.


  • I’m not being hostile, I just fail to understand how your point with multi phase standards has anything whatsoever to do with safety. Multiphase standards, and standard intercompatability are convenience issues, not safety issues, and therfore irrelevant to the discussion.

    And other standards notably, explicitly do NOT include all those safety standards. For example, the ground pin on UK plugs is longer than the L and N, which A) can be used to place child safety shutters in every single outlet, that are lifted out of the way when the ground pin is inserted and B) in the same vein ensure that GND is always the first prong to make contact. The wiring of UK plugs also requires a some slack in the L and GND wires, so that if the cable is yankes so hard the wires tear out of the plug, L is always the first to go.

    The internal fuse also allows you to safely use super thin gauge wiring on low power appliances, and allows you to create cheap, low power extension cords, that are still safe because they have a fuse in the plug (yes, in theory any country could do that, but resetable breakers are expensive, and replaceble fuses are inconvenient for the user, unless the contry already has a decades old standard surrounding them, and they’re already available for sale basically everywhere).

    If other plugs provide safe alternatives for the issues I’ve reiterated, shouldn’t we be looking at those plugs as safer alternatives?

    No. Not unless the current plug is outright dangerous. Rewriting an entire countries electric code, and introducing an entirely new type of plug, especially one which would be neither forward nor backward compatable with the old one, costs billions, and is a major nuisance for consumers in the transition phase. It’s simply not worth it, unless it’s necessary for fundamental safety.
