Re: How "optimised" is Pi OS, compared to Ubuntu 20.04?

So just picked up a RPI4 8GB, and pondering what OS to put on there (I have a Pi3B at the moment, running Raspbian). My real issue with Debian based OS are some of the packages are so old, it's really hard to get stuff working, many current packages in Debian maintainer's eyes are actually consider...

Would 8 raspberry-pi-zero's and a raspberry-pi-4B+ work?

There are however other ways of 'clustering' RPiZero boards.

You're saying that the RPI can output from HDMI to a screen, but there is no way to input through HDMI? Correct, that is what I am saying. In respect of an RPi board as shipped from the factory. are you sure no pi will accept any video input? That is not what you originally asked, and it is not wha...
