  • Some extension cords absolutely do have circuit breakers, I know this because we use them at work for some of our heavy duty equipment. I also know for a fact that fused link extension cords were their predecessor and you can buy both on Amazon still so I know they exist.

    Further I was not saying don’t use an extension cord with a welder. I was saying the correct gauged wire for that extension cord may be necessary to carry the load.

    The point of bringing up 110 vs 120 volts was to point out that more voltage = more push. More push through a smaller circuit than is recommended means more heat.

    Amperage is the draw, and it’s important because most devices are rated by draw rather than voltage, so what I said does make sense in that context. I wasn’t trying to say they were the same thing. The reason they’re rated in amperage is because the amperage is what kills you, and because thats what the safety devices are rated in. That’s how much of a draw they can withdtande before they break the circuit.

    I was also pretty exhausted when I responded so my explanation barely makes sense even to me, but I do see where I was going with that. Have you ever seen one of those old brown extension cords with three outlets? They’re usually 2 prong (don’t have a third prong for ground). They also don’t have any of the fail-safes that new extension cords do have.

    While I was not specifically talking about daisy-chaining power strips, I wanted to make it clear that even using multiple extension cords in a daisy-chain manner adds significant resistance to the circuit and with enough push and a big enough amperage appliance it absolutely is a fire hazard.

    I’m not sure where you got that I said you shouldn’t use an extension cord with a welder. I was saying you don’t need an extension cord worthy of powering a welder safely in order to power a lamp. But a smaller lower rated extension cord that works for a small indoor appliance is not up to the task and would be dangerous to use with a welder without the proper protections.

  • The short answer is rating changed. We got more and more devices that required higher amperage ratings. So we went from 110 (which was what most homes were rated for in the 50’s) to 120. But if you happened to have an old extension cord lying around in your basement from before the change etc you absolutely could overload it.

    The real problem though is that some devices you might use an extension cord for (lets say a welder because I know from experience those require more power than a standard 20’ extension cord puts out), require a certain gauge of wire to carry that power. If that wire is too small or the power source is insufficient, it’s likely no electricity will flow (without flaws in the circuit).

    There are various kinds of extension cords made for various uses. Longer = more money, fused = more money, larger wire = more money. More insulation/weather proof plugs = more money.

    You probably don’t need a big beefy extension cord for the lamp in the hallway. But you might need it for your weedwacker.

    But if, say you hooked up an outlet dedicated for something like a washer/dryer. And you used the correct extension cord to connect to that outlet. Now let’s say you attach an older extension cord or power strip to that extension cord. One that doesn’t have an internal breaker to trip (there’s definitely a fair number that didn’t, back in the day). It would be an astronomically bad idea to attach your welder (or any high draw device) to that circuit. You absolutely can and will let the smoke out of your wires and where there is smoke there is fire.


  • Yeah. I’m not sure it matters much that their content is similar. Using the DMCA system for something it clearly wasn’t intended for and then furthering that with what is ultimately a frivolous lawsuit (when you’re both copying a rich and famous influencer yourselves) is ridiculous especially with the Amazon algorithm giving them similar or the same items to schill to the public. This lawsuit is dumb (regardless of the minutiae). But it highlights how much of the algorithm builds these people’s “brands”.

    This may not be factually wrong but it’s not well written, and probably not written by a person with a good understanding of how Gen AI LLM’S actually work. This is an algorithm that generates the next most likely word or words based on its training data set using math. It doesn’t think. It doesn’t understand. It doesn’t have dopamine receptors in order to “feel”. It can’t view “feedback” in a positive or negative way.

    Now that I’ve gotten that out of the way, it is possible that what is happening here is that they trained the LLM on a data set that has a less than center bias. If it responds to a query with something generated statistically from that data set, and the people who own the LLM don’t want it to respond with that particular response they will add a guardrail to prevent it from using that response again. But if they don’t remove that information from the data set and retrain the model, then that bias may still show up in responses in other ways. And I think that’s what we’re seeing here.

    You can’t train a Harry Potter LLM on both the Harry Potter Books and Movies and the Harry Potter online fanfiction available and then tell it not to respond to questions about canon with fanfiction info if you don’t either separate and quarantine that fanfiction info, or remove it and retrain the LLM on a more curated data set.

    My dude, the vehicle could be working fine but you could live somewhere with no broadband and poor 4G connection and not be able to receive the update. Don’t assume that you just know how everyone who owns one of these cars lives their life because that’s not helpful to the conversation, and it’s not how the government functions. The government has to assume that if a recall for safety or security is being issued that people may not be able to receive that OTA over the air and may be required to go to a service center for it instead.

    Almost all new cars have OTA software updates. If one of them breaks something and then the car can’t get further updates, what then? You’ve never had a software update mess with your computer? Are you for real right now?



  • Data is tainted by people who now know that what they generate is being funneled into these models. Additionally models are having guardrails added to prevent problematic responses. Add to that the lack of clean data sets for training data and the amount of Gen AI generated data that is all over the web and you get a fairly clear picture of why the answers are getting worse.


  • They absolutely do have to notify people of mandatory recalls and it’s not even up to the company. This person does not know what they are talking about. There’s a difference between a mandatory recall (mandated by the NHTSA/Government), and a voluntary one. Every other car manufacture sends out information to their customers about mandatory recalls (yes, even software updates, yes, even when they’re OTA fixes). Tesla isn’t special. They still have to comply with the law.


  • You would absolutely take your vehicle in for service for a safety recall if the OTA didn’t work. Which happens frequently enough that it still warrants being called a recall and the necessary steps once the vehicles are “recalled” in order to notify customers who might not otherwise set themselves up to get an OTA. It’s not as simple as the car “just does it overnight” in every case.


  • Cool factor I think. Tech enthusiasts who wanted a car full of tech. The funny thing is automotive is having a tough time building quality vehicles recently across the board. The pandemic only seems to have exacerbated the problem but the trend is that even experienced car manufacturers are having recalls up the whazoo.


  • Recalls aren’t just something that magically happen. Usually there’s an investigation (by the NHTSA, or the company themselves). That investigation concludes that a recall is warranted or necessary and, in the case of voluntary recalls they do a cost to benefit analysis (like how Ford did when the Pinto was a bomb just waiting to be rear ended, and they realized they would save money by not recalling them).

    But the NHTSA does force quite a few car manufacturers to do mandatory recalls regardless of whether they want to or not, usually to do with health and safety. You know. To prevent the Ford Pinto scenario.

    So it’s not so much what they aren’t recalling (although I’m sure there’s quite a lot). The real question should be, why do they have so many recalls? Why aren’t they fixing the problems before they public gets a hold of these vehicles. And it’s not just Tesla we should be asking that question of.


  • The thing is though, if a drone is spying on you the police have to do something about it. And if they can’t or won’t then you document everything and when they show up saying you did something, you tell them “so you found the guy who’s been stalking me via drone?” /S for obvious reasons, but these laws are going to have to change sooner rather than later because there’s a lot going on that technically isn’t legal with drones but can’t be prosecuted by the legal system because of this law.

    Add that to the military airspace drones keep violating (not under FAA jurisdiction) and eventually this is going to be a problem that the government can’t ignore.
