Good on KDE and Valve for just doing HDR and bypassing the wayland people who have just sat on the PR for 3 years: https://invent.kde.org/plasma/kwin/-/merge_requests/4589 ; https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14

Havent heard of exploding-heads, I guess thats a good thing?

Karma is the total upvotes - downvotes across all posts made by an account on reddit; on the fediverse there is only upvotes (likes or boosts depending on implementation) and downvotes (dislikes) per post. Theoretically you could calculate it for your account, but because you cant display it anywhere (and it isnt used for anything) it wouldnt be of much use.

Oh, yeah I guess that would be an instance admin thing cause mine has a whole bunch in that settings box. Let them know that “undetermined” needs to be included as an selectable language.

On the web interface, go to your account settings and out of all the languages selected; ensure that “undefined” is one of them. You can select multiple languages by holding down the “control” key and clicking. For example, right now I have both “english” and “undefined” as the languages I use.
