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.

NAME
twiglet - observe or control an RVC-enabled machine's console SYNOPSIS
twiglet [OPTION]... host-specification DESCRIPTION
twiglet is a program for controlling another machine's console. It works using the RVC protocol, and an RVC server (such as rvcd(1)) must be running on the machine to be observed. Using twiglet, the a best effort attempt is made to duplicate the screen contents of the observed machine. If the machine is displaying a virtual text console, the text on the console is rendered in the terminal in which twiglet runs. If the machine is displaying an X ses- sion, and the RVC server supports VNC integration, twiglet will open a window that contains the current contents of the X display. It is also possible to control the observed machine in various ways. With keyboard control enabled (and with support from the RVC server), keys may be sent to the observed machine in text console mode almost as if they were typed from the keyboard. Twiglet also supports switching virtual console on the observed machine. Finally, if VNC integration is available, the X display can be manipulated almost as if the user were at the console. The intended use for twiglet is in training and teaching environments. The idea is that there are student machines and a control machine (which the trainer or teacher would be using), with a serial line attached to each student machine. The trainer or teacher can then ana- lyse the students' attempts to complete tasks, and help them out (showing them how to finish it) without needed to push them aside to get to the keyboard. This client is written using ncurses(3X). OPTIONS
--help display a help message and exit successfully --version display a version number and exit successfully -c, --control control the remote machine rather than just observing it -e xy, --escape xy set the escape character and the escape escape character (like screen(1)) The host-specification takes one of the following forms: host:port to connect to an RVC server over TCP tty [host] to communicate with an RVC server over a tty (for example a serial line); the optional hostname is for VNC integration BUGS
I'm sure there are bugs, but I don't know what they are. AUTHOR
