The n-queens problem

Our first computer science semester involved programming recursively. The teacher riled against the fact that we were learning our programming skills on an old DEC-VAX machine. He therefore challenged us to bring the system to its knees using a program of our choice, because he argued it would confront the university directors with the fact that the machine needed replacement with something more modern and stable.
So a co-ed of mine and I set out to program the n-queens problem, recursively mind you, and gradually increased the value of n. At some point we felt the calculations were taking too long and still in hope that we would finally meet the challenge, we stepped into the teacher's office. Unfortunately the teacher we were supposed to see wasn't there, but his colleague was, who was also less than impressed with our initiative. He told us off by saying that the machine should be used by other people too. The machine was still in use after 2 semesters of computer science classes.

SYSTEMD-MACHINE-ID-SETUP(1)				     systemd-machine-id-setup				       SYSTEMD-MACHINE-ID-SETUP(1)

NAME

       systemd-machine-id-setup - Initialize the machine ID in /etc/machine-id

SYNOPSIS

       systemd-machine-id-setup

DESCRIPTION

       systemd-machine-id-setup may be used by system installer tools to initialize the machine ID stored in /etc/machine-id at install time with
       a randomly generated ID. See machine-id(5) for more information about this file.

       This tool will execute no operation if /etc/machine-id is already initialized.

       If a valid D-Bus machine ID is already configured for the system, the D-Bus machine ID is copied and used to initialize the machine ID in
       /etc/machine-id.

       If run inside a KVM virtual machine and a UUID is passed via the -uuid option, this UUID is used to initialize the machine ID instead of a
       randomly generated one. The caller must ensure that the UUID passed is sufficiently unique and is different for every booted instanced of
       the VM.

       Similarly, if run inside a Linux container environment and a UUID is set for the container this is used to initialize the machine ID. For
       details see the documentation of the Container Interface[1].

OPTIONS

       The following options are understood:

       -h, --help
	   Prints a short help text and exits.

       --version
	   Prints a short version string and exits.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
