  • You keep saying that, but it’s not an extra step. Weighing the food is in place of the volume measurement, not in addition.

    Using volume measurement: start cutting broccoli. Add to a measuring cup until you get the right amount.

    Using weight measurement: cut broccoli. Add to scale until you have the right amount (actually I would usually weigh out a single large piece, then chop it all at once - same amount of effort).






  • Just a small note: the pressures in this chart are absolute, not gauge. In everyday usage (like talking about tire pressure) we mean gauge pressure - that is, the difference in pressure from atmospheric pressure.

    Your overall point is well taken (the change in temperature doesn’t matter much), but the numbers will be slightly different. For example, a tire filled to 100 psig (gauge) will reach 106.496 psig at 100 deg F, versus 105.663 in the original chart (assuming 14.7 psia atmospheric pressure).






  • The most intuitive analogy to federation to me is email. You may have an account with one provider (gmail.com in the example of email, or lemmy.world in the example of Lemmy) but you can send emails to other providers (email example) or post messages to other instances (Lemmy).

    Just like with email providers, a Lemmy instance may decide not to allow communication with another instance - this is “defederation.” Instances that allow communication are “federated.”

    Just like email, you don’t normally need to worry much about whether you are on the same instance as a particular community or user - it just works.

    This is a simplification, but for me is a good working model.


  • No, you need to include the height of the cylinder (a). Imagine a deep dish pizza (big a) versus a thin crust (small a) - the sides of the deep dish pizza have more area. Your formula returns the circumference of the pizza.

    If you’re interested in dimensional analysis (and why wouldn’t you be?) the formula you proposed doesn’t have enough length units. It would return a value of length (like inches, or cm) not area (like square inches or square cm).
