So I started to learn OpenGL, but the red book and blue book is just too detailed. I googled around, and knew that modern OpenGL is preferred (version 3 and above), however, the old Nehe's tutorial which is about OpenGL 1.x is still everywhere. To help beginners from digging too much into the old and deprecated way, here is a list of tutorials targeting modern OpenGL:

• Anton's OpenGL Tutorials     Great, updated frequently, but there is no source code provided. Good as a reference and starting point, but you just can't get anything up and running with it, you can just get the concept of how to do things in OpenGL.
• open.gl     not complete, but worth a view, the source code is elegant. Uses GLFW as window management
• OpenGL Tutorial     Great, the code is horriable, but somehow they did make it clear about what they are doing. Uses GLFW and glm.
• Tom Dalling's OpenGL Tutorials     Great, short and covers the basics
• Learning Modern 3D Graphics Programming     Great, intermediate
• ogldev's OpenGL Step by Step     Great, a little long(40 lessons), targeting linux
• OpenGL 3 and OpenGL 4 with GLSL     only source code, no guides, eclipse needed.
• Scratch a Pixel     a website about math used in Computer Graphics
• Swiftless's OpenGL Tutorial     not complete, outdated
• OpenGL Book     not complete
• Joe's     not complete
