Regarding the Xinu OS ("Xinu Is Not Unix"), I was incredibly fortunate to have
taken OS and Networking classes from Xinu's creator, Douglas Comer, at Purdue.
Xinu was a fantastic learning platform for an intro to OS's. I think we built
it from scratch on 486's (this was the late 1990's). Comer helped create a lot
of the original internet, and he had fantastic stories to drive the lessons
home.
I hadn't thought about Xinu in years - glad it's still alive and kicking!

I hadn't heard of Xenu, a simple OS created in the 80s for teaching. A better
Minix? This link points to a Git repo with a "version .1" port to small MPUs
like Atmega328 (the 8 bit chip in the R4 genuine Arduino board) as well as
larger ones. I gather the Xenu culture by necessity isn't oriented toward fancy
GUI IDEs?
Since Arduino was bought there hasn't seemed to be any big change to disrupt
use of the 1.8 or 2.3 IDEs. The design of 1.8 seems absolutely sweet with
respect to extensibility, giving allowing platform support a lot of lattitude.
I suspect the powers that be at Arduino are happy to let it sit at least until
pressure to monetize kicks in. In recent weeks I managed to get the 2.3 IDE to
interact with a Raspberry Pi Pico 2 via SWD (JTAG over two wires), but I find
this debug support on Linux very fragile.
I've never paid the dues to learn cmake properly but marvel at how well it
works to create make files. I can mindlessly copy files for cmake and make then
work pretty well.
But I confess I'm very fond of a dev flow involving vi, job control (cntrl-Z,
fg), make and gdb or some other effective debugger in a shell session. On my
current PCs the turnaround time from an edit after the debug "aha" to a new
debug session is small single digit seconds: very much faster than the time it
takes to click around in a GUI.

Thanks for that! And it leads on to a question I've had: given
Arduino was borged, what would be a decent replacement for its IDE?
And, what would be the penalty of using vi and make instead just like
Xenu wanted us to do?
