They have been working on a fully in-house open source laptop for some time but I don’t know the ETA on it.

Artemis is one of them but it is in a closed alpha right now afaik

Lemmy is much better for developer/admins. There is currently 10+ Lemmy apps in the works and 2 apps that supports both Lemmy and K.bin this is because K.bin doesn’t have a proper API documentation yet. Lemmy also has a better documentation for running your own instance and uses way less resources. Most of the Lemmy’s advantages are technical ones but it translates to user facing ones with more apps, more responsive, has more users and can scale better

It is because it shows the posts from Lemmy.world, Lemmy.ml and beehaw.org all at the same time. If you click the sorting button Up the top you can set it to only show one of them.

I don’t even have the language selection while posting from Jerboa. But like the others said most people probably won’t use it becuase it is annoying to find the language on the slider menu without a search functionality each time. It would be used more if instances and users could select a default language for themselves
