  • 240 in the neighborhood - i.e., that’s enough to distribute from the pole to a few houses. Of course you have higher voltages to go longer distances. This is equally true for AC vs DC. Thus, the idea that it takes a looot of copper for DC is erroneous.

    In fact, where conductor size is relevant is that you can use smaller conductors for DC, because of the skin effect.

    Wiring: Split phase, that is also usable as 240 for large appliances. So, the latter.



  • Yeah. Basically, the biggest reasons for AC have to do with voltage stepping up and down, and for instant grid load knowledge. Well, and of course, existing infrastructure.

    Both have solutions, but aren’t as cheap as they are for AC. But, aside from that, DC has a lot of benefits, particularly in end usage efficiency and transmission over distance.

    Back in the day, the capability to easily bump up or down the voltage of electricity just wasn’t there for DC, so AC was the distance winner (high voltage is needed for distance, low voltage typically needed for usage).


  • I mean, you need a lot of voltage to make voltage drop irrelevant. Like, 120 or 240 volts. If distribution is voltage is the same dc/ac, we could use the same wiring (but different breakers, and everything else).

    So the wiring argument doesn’t really hold up - the question is more about efficient converters to reduce voltage once it’s at the house.

    I.e., for typical American distribution, it’s 240 in the neighborhood and drops to 120 in the house. If the dc does the same, the same amount of power can be drawn along existing wires.






  • Are you telling someone what they need to do to get windows, converting from Linux?

    I made it clear they support different things, even though there’s significant overlap - and that means some of what Windows supports, Linux doesn’t, which is critical info if you’re switching from Windows to Linux. If someone were asking he reverse, I would likely tell them the reverse (if, for example, they were used to running a pi).




  • Interesting point, but when people want to switch, and they hear Linux can do everything that windows can, they will think that everything they can do on windows can be done on Linux. To make everyone happy, Linux must be a superset. That’s a tough ask.

    Another thing Linux can’t do: Run all hardware on many new computers.

    Not that much of a problem, just buy different hardware or wait - they’ll address the works. But if someone just bought fancy new hardware, and wants to put Linux on it, there is a decent chance of running into sore spots, or of Linux not booting at all.

    That said, it would be pretty clear to say “Linux can’t do everything windows can, and windows can’t do everything Linux can. But for most cases, there’s enough overlap that you’ll be happy on Linux.”

    Edit: wording, additional stuff


  • Not really involved in this conversation, but you are literally calling this guy a smuglord while smugly treating him like he’s an idiot.

    The way you’re using that meme looks like smug feelgood self-supporting blanket rejection of any argument as being from a ‘smuglord’.

    Grow up. Live your communist dream, but if you try to shove it down someone’s throat, particularly in an inapplicable situation, don’t be surprised if you find yourself choking instead.
