  • it’s actively hiding an instance as if it doesn’t exist

    For the purpose of directing new users, who tend to just pick the largest instance, sure. But if you and they are both federated, there’s no difference in the content.

    So what do they do when the next instance gets “too big” for their liking? Hide it, along side LW? And the next?

    Correct, because this increases the reliability of the average lemmy user’s experience as one point of failure affects fewer users.

    Dry bulb is the temperature independent of humidity. Wet bulb is has a wet cloth on the thermometer bulb. This simulates how much sweat cools you in the current humidity and wind.

    Measuring humidity instead and cross-referencing to get heat index is more common these days, but IMO it’s worse. 120 in the desert vs 120 heat index due to humidity is the difference between someone using a hair dryer on your face and getting cooked in a steam room, and it doesn’t consider wind and cloud cover.

    100F was defined as the human body temperature (The guy they used had a cold or something so it’s off by a degree and a half.)

    That’s useful for perception of heat. When the dry bulb gets above 100F, wind only cools you down by sweat evaporation, and when the wet bulb gets above 100F, even that can’t cool you down, and you will die if you don’t get to a cooler or drier environment.

    This is more intuitive than 36.5C.

    But really it is much better for human temperatures.

    It’s just intuitive, 0F is 100% cold, and 100F is 100% hot.

    When the dry bulb gets above 100F, wind only cools you down by sweat evaporation, and when the wet bulb gets above 100F, even that can’t cool you down, and you will die if you don’t get to a cooler or drier environment.
