OpenGL ES 2.0 is not backward compatible with 1.x
OpenGL can manipulate a frame buffer for a screen. The pixels in a window which are controlled by an opengl context belongs to this opengl. If this is overlaid by another window then OpenGL needs to know it doesn't own these pixels.
What is precision qualifier in gls?
What is Gouraud Shading?
you have the standard input and output variables. You also have some types that are unique to glsl. For example attribute variables that are specific to a vertex. There are "uniform" variables that cuts across all vertices. There are reserved variables, there are built-in variables etc. This page will throw some light on this type of variables.

You see in OpenGL literature the terms VAO and VBO being referred. These are Vertex Array Object and Vertex Buffer Object respectively. A vertex buffer deals with the memory area storing the vertex information. Pure data byte after byte. A VAO, vertex array object, is a structure that describes how opengl should interpret the data that in the VBO.
In es 1.0, I was able to use indexing into an existing vertex buffer in the glDrawElements method. This allowed me to specify only 4 points for drawing a square or rectangle. without the indexing I would have needed 6 points making up 2 triangles. How could I do this in ES 2.0?

Nice explanation from opengl.org
OpenGL allows extensions by hardware vendors. OpenGL has a protocol and low level API to discover what these extensions are and the supported functions. Using extensions in your C++ code is - unfortunately - platform specific. The address of the function (function pointer) must be retrieved from the OpenGL implementation (e.g. hardware driver). Under Windows this can be done using "wglGetProcAddress".
GLEW is a common API to write portable code which internally hides the platform specific detail. So you will be downloading GLEW for each platform and the client programs can stay portable as long as the target platform supports a GLEW implementation.

What is HAML?
From Scientificamerican
New research suggests that when we are older these kinds of ?if only!? thoughts about the choices we made may not be so good for our mental health. One of the most important determinants of our emotional well being in our golden years might be whether we learn to stop worrying about what might have been.

I have a medium to a large enterprise. The software we are producing is buggy. It is brittle. It often fails. It is often down. It often allows me to delete things that I shouldn't be able to. It takes too long to respond. It is slow. It gives unexpected results. It doesn't stop me from shooting myself in the foot. Why does this happen and how can I improve the state of code quality in my enterprise?
