  • I’ve setup okular signing and it worked, but I believe it was with a mime certificate tied to my email (and not pgp keys). If you want I can try to figure out exactly what I did to make it work.

    Briefly off the top of my head, I believe it was

    1. Getting a mime certificate for my email from an authority that provides them. There’s one Italian company that will do this for any email for free.
    2. Converting the mime certificate to some other format
    3. Importing the certificate to Thunderbird’s (or maybe it was Firefox’s) certificate store (and as a sidequest setting up Thunderbird to sign email with that certificate
    4. Telling Okular to use the Thunderbird/Firefox certificate store as the place to find certificates

    I can’t remember if there was a way to do this with pgp certificates easily





  • I’d be surprised if it was significantly less. A comparable 70 billion parameter model from llama requires about 120GB to store. Supposedly the largest current chatgpt goes up to 170 billion parameters, which would take a couple hundred GB to store. There are ways to tradeoff some accuracy in order to save a bunch of space, but you’re not going to get it under tens of GB.

    These models really are going through that many Gb of parameters once for every word in the output. GPUs and tensor processors are crazy fast. For comparison, think about how much data a GPU generates for 4k60 video display. Its like 1GB per second. And the recommended memory speed required to generate that image is like 400GB per second. Crazy fast.







  • 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




  • There are a great variety of co-ops. If you define renting narrowly enough, then they are of course different. But the point is that for some (and the co-ops I’ve seen personally) you don’t have to make a down payment for a mortgage like you do with a condo or house. You instead pay a monthly fee that covers the co-op’s mortgage/repairs/taxes. Or if the place is fully owned by the co-op, then just the repairs/taxes.

    But you retain the flexibility of renting in that you can leave reasonably easily since you’re not personally responsible for the mortgage.

    I think there are also co-ops (possibly more commonly) where it’s essentially just a condo where the building is collectively owned by the tenants instead of a for profit company. In that case, it’s much less like renting.
