Correct, but new users don't want to need the command line for something as simple as installing packages.

The only window is Firefox, which makes it hard to tell, but I'd guess it's GNOME with the Aylur extension.

Heat difference is what you can get energy from, not heat itself. You need something cold to get energy from the heat.

Luckily, pretty much any modern x86 CPU works about as well as any other. I've had a Ryzen CPU for about three years and an Intel CPU before that, and I notice no differences (apart from obviously the faster CPU being faster).

Yes, and also RCS.

I used Google Messages directly for a while, but then a Matrix bridge that uses Google Messages was released, so now I use that. If you want to try it, matrix-docker-ansible-deploy makes it really easy to self-host, but if you don't want to do that, something like Beeper can probably do it.

EMS doesn't support bridges unless you pay for the highest tier, but the list you linked is good.

etke.cc does that.

Also rooting in the first place and installing "modules" that extend functionality.
