If as a user that wants to look at the running processes, let me see the running processes. Don't hide it from me.
Techniques to hide running processes may also be picked up by some anti virus as potential threats.
Don't do it.

Maybe you could do the work inside of a thread instead of forking a new process. I'm not sure if that would accomplish your goals though, since you're not specific about what you need multiple processes for. | 2 | 1 | 0 | I would like to know if it's possible to run Python application subprocess in such way that there wouldn't be duplicate process in task manager? | How to run invisible subprocess in Python? | 0 | 0 | 0 | 1,893 |

Since you are just learning I'll not post the exact code so you'll have a chance to figure it out on your own. | 1 | 2 | 0 | So I'm coding Pacman in Python just for fun and I want to create pacman's open face (when he is eating food) using Tkinter graphics. How exactly do I draw an open face? I was thinking about using canvas.create_arc to create the open mouth but it doesn't work properly :(
Any help? Thanks! | Drawing Pacman's Face in Tkinter | 1.2 | 0 | 0 | 2,778 |

If the resources are all different for the same user, it is because the user is logged on from several different clients, perhaps from multiple different machines. You will get presence updates from all of the user's clients if you're subscribed to them. | 2 | 2 | 0 | I am using sleekxmpp to connect to Google Talk.
