  • Let me take this a step absurdly far:

    You may be slightly more buoyant (and therefore apply less force on a scale) everytime you breath in. It’s not the presence of air that has this effect, it’s the decrease in density of your total body (mass/volume) that has that effect. (Helium just contributes a fractional more difference in density compared to air, but how much you breath in probably matters much more than what you breath)

    Except, maybe not. Because the air you breath in partially dissolves in your blood. Dissolved matter does not decrease density, rather the opposite: it packs tightly into the voids, increasing mass for the same volume.

    How much of an effect this has is hugely debatable, probably depends on a dozen biological and circumstantial factors, and this is where my knowledge ends. But it’s fun to imagine.

    However, if you can imagine inhaling but holding your breath at the same time, creating a vacuum in your lungs, then yes, you would be more buoyant, even more than inhaling helium, and the scale would read slightly less.








  • Here in Canada, I find the prices pretty neck and neck. Small items tend to be a bit cheaper at the stores, since there is very little overhead for them to carry small items compared to Amazon’s picking and delivery logistics. Big items tend to be a bit cheaper on Amazon. For tech specifically, Best Buy price matches items, so it’s not that bad… Memory express and CC sometimes have lower prices than Amazon too (see PCPartPicker).

    The main reason to use Amazon is you can easily find some really obscure stuff. Then again, you can buy direct from manufacturer, like Vevor, for often cheaper.













  • Before I understood Docker, I used to have HA installed directly on bare metal side by side with other “desktop” apps.

    To be able to access devices, HA needs many different OS-level configurations (users, startup, binding serial ports, and much more I don’t have a clue about). It was a giant mess. The bare OS configuration was polluted with HA configurations. Worse, on updating HA, not only did these configurations change, the installation of HA changed enough that every update would break HA and even the bare OS would break in some ways because of configuration conflicts.

    Could this be managed properly through long term migration? Yeah, probably, but this is probably a ton of work, for which a purpose-built solution already exists: Docker. Between that and the extra layer of security afforded by dedicating an OS to HA (bare metal or virtualized), discouraging the installation of HA in a non-dedicated environment was a no brainer.
