I’ve seen them used in power supplies that are not supposed to be user-servicable.

but will also work with a Phillips screwdriver

Only if you hate the screw and never want to see it in its full glory again.

Lemmy is also more of alpha-quality software. The admin tools are pretty much non-existent. On my own instance, I’ve had to go into the database to fix issues a lot using straight SQL, and I have like ten users on the platform. One of those issues caused my admin account to no longer being able to log in, another caused the whole instance to be down.

Well, my home instance has defederated from lemmy.world due to this, that’s why I had to create a local account here.
