Phong illumination model (cheat sheet)

$$ f(  \vec p ) = \underbrace{I_a K_a}_{\color{red} \text{ambient component}} + \underbrace{\sum_i^\text{nb_lights} (\vec n( \vec p ) . \vec l_i) K_d I_i}_{\color{green} \text{diffuse component}} + \underbrace{\sum_i^\text{nb_lights} f_{spec}(\vec l_i( \vec p ), \vec v(\vec p)) K_s I_i}_{\color{blue} \text{specular component}} $$

I summarize the Phong illumination model with the above equation and explain all the terms one by one.

Drag and drop not working in QTDesigner or QTCreator designer

This has upset me for some time and I finally found a forum entry solving this problem.

The problem: I wasn't able to drag&drop in QTDesigner any widgets from the widgets list to the form I was editing.
Solution found here: qtforum.org

You only need to add this entry to your /etc/X11/xorg.conf:

Broken F4 shortcut in Qtcreator for cuda files ".cu"

Well I'm using QtCreator to code my CUDA project and there has been a lot of things bothering me. Among them is this F4 shortcut which doesn't work.
