New Tutorial for OpenGL: 3.x+?

[dime]

Anyone have a new tutorial on lwjgl using OpenGL 3.x and above?  Things like glBegin and quads are supposedly deprecated.
I'm trying to follow this tutorial but getting stuck on a few parts in regard to bindBuffer/drawElements in the rendering section.  (That is, it crashes).

In drawElement (in lwjgl)  what are the indices?  A byteBuffer of the ids of the FloatBuffers that contain the vertexArray?
