  • As far as I’m aware, what you cited only proves that there is no ether that acts on light in a way such that the round trip time in the direction of ether travel is different from the round trip time in the direction perpendicular to ether travel.

    It’s not merely that:

    somehow the movement of this medium caused the speed of light in one direction to be faster than another due to the movement of this medium, measuring the speed in two directions perpendicular to each other would reveal that difference.

    Instead, it’s that the speed of light must be different in the two directions in a way such that their round trip times don’t average out to the same average as in the other direction.

    The theories of ether at the time predicted such a round trip difference because of the wind like interactions that you say.

    I believe that this in no way proves anything about the one way speed of light. The Michaelson Morley inteferometer only measures difference in round trip time.

    (Insert comment about the irony of your last statement). See https://en.m.wikipedia.org/wiki/One-way_speed_of_light










  • I agree that the internet is far more than facebook. But if you’re blocked at the edge of the network by your ISP, there’s really not much you can do. You’ll have access to nothing, Facebook or otherwise. Not even something low bandwidth.

    If At&t, Comcast, Charter, Verizon, and T-Mobile suddenly stopped providing service to all their customers, then essentially no-one would be able to use anything on the internet at all. Even if the backbone itself (which I believe is largely owned by those same companies, but not sure) and some large datacenters that are their own isps were able to keep talking to each other, anything business or user facing would stop.

    Some people who run their own mesh networks might be able to stay in contact (and people would try and start some local ones as this disaster unfolds), but that’s so few people.



  • That make sense. I would use tags like that:

    • Flickr Published

    • year roundup/2022

    • type/Landscapes

    • type/Portraits

    • events/trips/Zion 2022

    • content/food

    • content/animals

    I actually do event level as my on-disk sorting. And then tag for stuff that’s not that. But I think it would work pretty well to do the event sorting under tags as well.

    Then I rate my favorite photos, usually using the green approved, not stars. But stars would work too. Then if you want to find say, favorite landscapes, the digikam interface makes it really easy to do so.

    I’m not sure if you can select what tags get written into the image, but if you can, you might be able to exclude certain parts of the hierarchy, and only include content/ or type/ subhierarchies
