    There’s less and less reason to do it (and it’s never 5). On systems without floating point you might want to round it a bit, but only if the specific thing you’re doing allows it, and even then you’re more likely to do a fixed-point approach by using e.g. 314 and dividing by 100 later, or adjusting that value a bit so you can divide by 128 via bitshift if you’re on a chip where division is expensive. However, in 2025 you almost certainly should have picked a chip with an FPU if you’re doing trigonometry.

    And while rounding pi to 3 or 4 is certainly just a meme, there are other approximations which are used, like small-angle approximations, where things like sin(x) can be simplified to just x for a sufficiently small x.


  • Which country is this? I think both American and European (or at least Norwegian) washers use standard plugs (although American dryers do not), so I’m just curious which areas use something custom for that.

    A regular plug should be able to supply a washer with power, but dryers are a different story in countries using 110V power.

    • It can tell you it’s done, so you notice the notification after a couple hours instead of finding musky clothes a day or two later
    • It can tell you it’s time to do the self-cleaning cycle
    • If you’re doing something unusual, like washing reusable diapers which need extra rinse cycles, you can upload a custom program for that to the washer
    • Even more unusual, someone had stacked units and was too short to reach the buttons on the washer, so they liked to start it via the app instead of getting a stool

    Most of this can be achieved in other ways (like a smart plug measuring the current draw and a simple monthly reminder), but non-techies want turnkey solutions.

    I can’t see any reason to have WiFi on your dryer, though.






  • You are worthy of love, and there is someone out there for you, somewhere.

    I totally get your feelings about dating sites, although I dislike them for different reasons. Maybe it’s better to try meeting people through other means?

    You could join some kind of club which interests you and meet people that way, perhaps? It might take some pressure off, since you’re just doing something you enjoy and meeting people in the process. Maybe you get a new friend or even partner, maybe not.

    There are even specific events for single people, where you do some activity together. I don’t know how the dynamic is on those events, though, because clearly they all know why they’re really there.









  • Running copper between different buildings like that is risky, because if they have different ground potential you could get current traveling through the cable and zapping the equipment. A lot of people use fiber for those runs for that reason.

    If you want to solve your issue as cheaply as possible while eliminating the aforementioned risk, move AP2 to where AP1 is and replace AP2 with a PoE-powered access point. This will ensure all devices are powered from the same house, and you get rid of the failing device.
