Hello Linux Geeksters. As you may know, Gnome Pie is a circular application launcher, enabling the users to easily access their favorite apps, which they have added to the pie. For usage information, see this link.

The latest version available is Gnome Pie 0.5.7 which has been released a while ago, coming with the below changes:
- New Feature: Maximum activation radius: It can be set in the settings menu

- removed old GTK2 code
- removed a lot deprecated code
- switched from libunique to GLib.Application

In this article I will show you how to install Gnome Pie 0.5.7 on Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise Pangolin, using GNOME as the default desktop environment.
Because it is available via PPA, installing Gnome Pie 0.5.7 on the latest Ubuntu systems is easy. All you have to do is add the PPA to your system, update the local repository index and install the gnome-pie package. Like this:
$ sudo add-apt-repository ppa:simonschneegans/testing
