I have for many years teaching computer science for free and the purpose behind this work to increase people's awareness of this science that make the world a small village in addition to educate people and enlighten their thinking and make it is not associated with ideas of old, which leads to progress and change their way of thinking and make them try to develop themselves and the society they live in.
My only hope is to make people more aware of this in order to end the underdevelopment.
