  • You get 3-phase in the US if you live in a large apartment complex. Especially if it has an elevator. Since this combines to get 208V, the math works out to making your 240V stove only 75% of what it should be.

    For residential use, split phase is fine. We just run the two legs to get 240V on the specific things that need it. That’s generally electric stoves, water heaters, AC unit, electric dryer, and more recently, EV chargers. 3-phase is great when you’re driving something that spins with a high draw, and of those, only the AC unit does that (electric dryers spend most of their electricity heating, not spinning).



  • Have to drop the US number by 20% for continuous loads like a kettle would be.

    That said, US homes built in the last 40 years or so tend to have a lot of separate circuits in the kitchen. My house has one for the fridge, one for the disposal, one for the dishwasher, one for the lights that’s shared with lights in adjacent areas, stove has its own 240V outlet, and then one for all the other plugs. If I ran the microwave and a kettle and a mixer all at once, I’d probably still trip it, but that’s a lot of multitasking going on.



  • Microwave magnetron efficiency is around 65%. Since a kettle turns electricity directly into heat, it’s basically 100% efficient.

    A caveat is that microwaves will heat water directly and won’t lose as much to its surroundings. This is similar to why induction stoves are more efficient; they’re less efficient on paper than direct electric heating or burning gas, but they heat the thing you want in a more direct way.

    Even so, a microwave isn’t great for this task. If you’re short on space and don’t want even a small travel kettle, I can see why you’d take this option. Otherwise, no.






  • Yeah, those are mostly showing off. They’re not really what I’m getting at, either. I more want to challenge people to make useful things simply.

    And yes, there are ways that JavaScript can be used to give users a faster and more streamlined experience. The web as it stands is so far past that justification. I swear there’s lots of “full stack” devs that haven’t a clue how to make a site without React.


  • I’d like full stack developers to try something. Next time you have an itch for a personal project, see if you can make it with no frontend JavaScript. Just some CSS and HTML forms. All templating handled on the backend. Just try it and see how far you get. Don’t worry if it looks like a GeoCities page.

    Then try finding places where JavaScript would make it more responsive or better UX in some way. Does the back button still work? Is it actually faster? Does it provide any benefit at all?

    Maybe it does, but just try.



  • AWS has a multitude of different offerings with confusing pricing structures. They have zero incentive to make them understandable.

    That said, chances are your new company has people who understand this already and know how to manage it. Hopefully, they’ll put up some guardrails that prevent you and others from running up a big bill. I wouldn’t expect a junior programmer to know how to do this, but that’s ok as long as the company is managed right. Granted, that can be a big if sometimes.
