Thank you for this nice thread! My question: what is Wayland all about? Why would I want to use it and not any of the older alternatives?

It was always that name. Electricity is named after the fish.

Maybe they have one machine set up to fill the bottles. In one market they are required to deliver a safety margin of 3%. So they put 618 in a 600 bottle. In the other market there is no such requirement. So they write 618 on the bottle.
