What is legally defined as personal data in this case? Public usernames, public posts, or private messages to another instance, which states clearly that messages aren’t private and to use Matrix instead? Or is there something else?

How? I just read the full text of that website, and I couldn’t find any language in there that would harm the fediverse.

Cult. MAGA is a cult.

btw i use nano

I’ve been using NixOS for about 3 years. Probably going to switch back to Arch, though.

That can be done with a single chip. What’s actually complicated here is the switch-mode power supply itself.

It’s how you get a 90% efficiency vs a 10% efficiency from linear power supplies (transformer, full bridge rectifier, and a big ass-capacitor, then if you need a stable voltage, a voltage regulator, which makes things even less efficient). The benefit of linear supplies is that it’s very easy to produce very clean power for analog electronics, but digital electronics have a lot more wiggle room for noise in the power. Well designed SMPS have both low noise levels and also hogh efficiency. Those are more expensive :P.

There’s a field of engineering specific to power electronics. It can get super complicated. I don’t understand a lot of it myself.
