"Everything is a file" is what made me start understanding linux few years ago and from there it got easier to use with each new concept.
Still this was really revolutionary to me when I first heard it. Made a bunch of things just click.

Yeah I'm interested in how that works too.
I've recently been looking at the Nextcloud "all in one" Docker image. It works by mounting the docker.sock file into the master container, which allows that container to stand up a whole bunch of other containers on your machine.
How would that work on Windows, if the Docker socket isn't a file handle?
AIO is a fun one to setup. I found it much easier with portainer. The thing that always catches me with Docker is the permissions after it's setup. I had nextcloud up for a week I could access my external hdd over Webdav and nothing else haha.
Docker Desktop handles the abstraction in Windows and MacOS. The container thinks it mounted a file.
Oh that's interesting. I wonder why they do it that way, considering macOS is a Unix OS.
I dunno, but it's a pain. Hiding low-level components from the user to make it more user-friendly.
I have an old 2014 macbook with a busted GPU temp sensor. The Mac firmware assumes the worst - that the computer is dangerously overheated - and therefore throttles back the CPU by 80% and runs the fans at full blast.
Fixing it on Mac required a number of third-party tools and flashing a custom firmware. I then installed Linux on the device - about ten lines of script that read from the working temp sensor on the CPU die and write a scaled value to /sys/ in response.
So much flippin easier on Linux.
I just said that Docker Desktop handles it. I've never used a Mac so I don't know for sure what's going on under the hood there but I imagine that everything they can do the same between Mac and Linux, they do. It's easier that way.
