I would like Conky to only show up on one viewport/desktop. I did use the Gnome feature to predefine viewports for specific window classes, but this feature does not work for Conky. Even moving it manually to another viewport does not work, because it jumps back to the first viewport, as it refreshes.

So... is it possible to configure Conky to define the viewport it is displayed on?

I want to change my wallpaper in Ubuntu 11.10 (with Unity) in a small Python script. I found the possibility to change it via the gconf-editor in /desktop/gnome/background/picture_filename. With python-gconf, I'm able to change the necessary values.

Apparently, the gconf string is not read out. If I change it (either via a script or via gconf-editor), the wallpaper remains and in the menu of "Change wallpaper", the old wallpaper is shown.

How am I able to change the wallpaper for Unity via a Python script?

The following code does work.

#!/usr/bin/python
# -*- coding: utf-8 -*-
from gi.repository import Gio

class BackgroundChanger():
        SCHEMA = 'org.gnome.desktop.background'
        KEY = 'picture-uri'

        def change_background(self, filename):
                gsettings = Gio.Settings.new(self.SCHEMA)
                print(gsettings.get_string(self.KEY))
                print(gsettings.set_string(self.KEY, "file://" + filename))
                gsettings.apply()
                print(gsettings.get_string(self.KEY))

if __name__ == "__main__":
        BackgroundChanger().change_background("/home/user/existing.jpg")

I would like to use a software to control which program may connect to the internet. I know that this behaviour is associated with the word "firewall", but some Linux users are very upset if somebody demands a Personal Firewall. I don't want to upset you by demand such a program.
I don't want to "secure ports" or other stuff a Personal Firewall promises on Windows. I looked into iptables but it does not fit my requirements.

I saw an excellent answer here ("How to block internet access for wine applications") but it's very uncomfortable to set this up.

Is there a software that asks for each program if it may access the internet?
