Linux

The easiest way to root an Android phone on linux is to use Heimdall. Heimdall is an open source program to flash Android on Samsung Galaxy devices.

Heimdall is available as a binary executable for many platforms, including Debian. Unfortunately, since I use Fedora, I had to compile the code from scratch.
First install all the needed tools.

There is no easy way to configure the location where screenshots get saved using gnome-screenshot.

In order to set this option, install dconf-editor package:

Here's a one-liner that will save some time. Uses sed, uniq, sort and of course regular expressions.

yum remove `yum search enlightenment | awk '{print $1}' | sed -e 's/.\(x86_64\|i686\|noarch\)//' -e '/^[:=]/d' -e 's/\(Loaded\|font-manager\)//' | uniq | sort`

What does it do?

It uses yum to remove all packages that are related to the Enlightenment Window Manager.

VirtualBox is a great way to test different platforms without actually installing them. It creates a perfect virtual machine to play with. Of course, a dummy virtual machine is of no use, until you install on OS on it.
