Getting on with OpenGL

Getting on with OpenGL
Hi all,

It’s a long time from the first time period I started to learn OpenGL as a beginner of that language. Now I have forgotten almost everything
about that language and need to re-start. At the foregoing time I suppose the link below was suggested for me to commence learning OpenGL:

My questions are:
1- Is this webpage still the best way to start learning OpenGl for a beginner?
2- Is it up-to-date or is there any better one for me to start which is straightforward, easy to read, complete and new, please?
What is your recommendation please?

watch the answer in ;))
