I have a project assigned to me by OS teacher to choose any Linux service and improve it. Currently I am totally blank in this. I am not sure which service should I use which can easily be implemented and my project just get finished. Can you guys help me out to choose a service which can easily be improved and implemented?
One idea which is in my mind right now is that currently we can stop any process (just consider client processes to keep things easy) but I think there is no option to pause the process? So i am thinking to implement this so that user can pause their running process.
