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.

MACHINE-INFO(5) 						   machine-info 						   MACHINE-INFO(5)

NAME
machine-info - Local machine information file SYNOPSIS
/etc/machine-info DESCRIPTION
The /etc/machine-info file contains machine meta data. The basic file format of machine-info is a newline-separated list of environment-like shell-compatible variable assignments. It is possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported, allowing applications to read the file without implementing a shell compatible execution engine. /etc/machine-info contains meta data about the machine that is set by the user or administrator. Depending on the operating system other configuration files might be checked for machine information as well, however only as fallback. OPTIONS
The following machine meta data parameters may be set using /etc/machine-info: PRETTY_HOSTNAME= A pretty human-readable UTF8 machine identifier string. This should contain a name like Lennart's Laptop which is useful to present to the user and does not suffer by the syntax limitations of internet domain names. If possible the internet host name as configured in /etc/hostname should be kept similar to this one. Example: if this value is Lennart's Computer an Internet host name of lennarts-computer might be a good choice. If this parameter is not set an application should fall back to the Internet host name for presentation purposes. ICON_NAME= An icon identifying this machine according to the XDG Icon Naming Specification[1]. If this parameter is not set an application should fall back to computer or a similar icon name. EXAMPLE
PRETTY_HOSTNAME="Lennart's Computer" ICON_NAME=computer-laptop SEE ALSO
