  • 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









  • 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’s definitely software that uses parts of the windows API that games don’t touch. And doesn’t work properly on Wine. I keep a windows install around just for using an analysis software for some lab equipment that refuses to start in wine.

    Things like CAD software are also a struggle, though the latest wine seems to have resolved a number of graphics issues with getting PTC Creo to properly use the nvapi and nvidia graphics drivers through wine.

    While wine is amazing, plenty of things don’t work with it. Usually you don’t need them, but if you do, you do
