OpenGL 4.0 Core Test: No more fixed funtion pipeline?

Here is a quick test of OpenGL 4.0 I’ve done to test the “new” way of OpenGL.
As you may know, since OpenGL 3.1 the fixed function pipeline has been deprecated so everything about shading is done with GLSL shaders.
I’ve made a simple example using Vertex Buffer Objects to organize geometric data and a simple GLSL shader to colour the cube.
