I've been using a nifty little program the past week  and I must say, its very useful. When using a ssh terminal, any program that is running is stopped when the ssh terminal closes. screen allows you to leave the terminal and come back to it later. To use screen,,, type screen... yup, that's it. there's some other commands to get through it like ctrl+a d detaches from the port, ctrl+a c makes a new screen, a screen -ls shows you the name of all the screens and screen -r <name> attaches back to the screen. I'm also using top. It allows me to see who is using what of the computer. Its all little tricks and stuff. Top is useful, because if someone is using that computer with a cpu intensive task then the program to be run might become slow.
