there is new opengl samples coming up at https://github.com/nvpro-samples
many of which I was happy to work on. Will keep this thread updated every time I'll add something.
So far there is one on the brand new NV_command_list extension, which allows cool new rendering techniques in OpenGL, some principles are similar to what is found in other new apis.
