One mildly interesting fact MANY programmers get wrong about the is_computer_on function:

It is threadsafe. The documentation is very clear about this.

Maybe something about programs being able to skip the 'is there a power cord connected to this PSU?' type jesting?

You could legitimately have a is_computer_on function. Some devices have wake-on-lan type functionality. What about the code involved?
