Stages of POSIX enlightenment:
Most people stop at stage 2, stage 3 hits when you decide to write a filesystem, stage 4 when you've finished your first filesystem. Stage 5 is when you start working on kernel internals. No one can tell you how to reach stage 6, you must discover it for yourself.
It makes more sense when you realize that it's not that everything is files it's that everything can be treated as a file. There are other APIs to interact with things, but everything can be interacted with as if it was a file. It doesn't seem as bonkers like this.
Yep, takes a moment to wrap your head around but the longer you read linux/unix documentation, the more it makes sense why it is the case.
Want take it to 11 plan 9 did it.
In Windows land, it's HANDLEs...which is typedef void* HANDLE IIRC
Well, if you go back far enough you might encounter punch cards or even switches, but then again you're not taking about modern computers anymore.
But some things are directories (like cgroups). And Networknamespaces were also controled in a weird way.
And then there are kernel features which are not exposed through a file or syscall but through a special type of socket.
Ok you got me with this one.
Btw the mitochondria are the powerhouse of the cell.
Epstein's?
