Not sure how much more it would cost to run. If you only really talk about stuff a pi can do as well, you wont be maxing out your cores. You will use a bit more maybe. Nothing sort of whatever you only really keep in mind for monero mining.
Those zero 3W sticks have been unavailable ever since I saw it here.
My brother in christ. A used PC has powersupply, case, storage and cooling. This is about the basic kit you need for a proper pi5 experience. You can very easily hit the 100 dollar mark.
Also, most of the used business PC will have 8G RAM, which would put your little ARM funsies up to the $130 budget range.
And you would still only have 4 shitty cores, no expandability.
You can get 2 Ampere ARM cores, 4G RAM and 40G space for that money at hetzner.
Linux has Pulseaudio/Pipewire. You can stream audio on the network in arbitrary ways.
It is important, as closed source software can determine its own defaults, hijacking the initiative and eventually gaining majority. Just like Google is doing with Android and Chromium.
Threads also wants to be part of the fediverse.
Spartans were way better trained as being royalty who should have been exclusively occupied with warfare in addition to their own propaganda that they were invaders and that the helots would betray them first time they could.
Practicing on live helots, being barred from politics until you were old enough and the puritanism all played into making them the most formidable.
I think that despite spartan losses, they almost always had the edge in the training and morale for the average citizen.
Sparta feels like if the Navy seals lead a state. The Shogunate feels more like a long lived junta with feudalism.
