Thank you for this GL3 triangle example!

I stumbled across a great OpenGL 3 online book with focus on OpenGL 3.3 and the programmable pipeline!
Jason L. McKesson: Learning Modern 3D Graphics Programming
http://arcsynthesis.org/gltut/

The MIT licensed source for this book is found on Bitbucket, a neat collection of example projects to port :)

I will read up and prime myself.
Focusing on OpenGL 3 now is a good way to get familiar with the new mobile OpenGL ES 3 devices that use a subset of GL3.
