so... wait... are you making a lot of money out of that? does it get you hot chicks? is this a part of your long term plan somehow? Is this piece of knowledge applicable in other aspects of life? does it give you everlasting happiness? Understanding a technical aspect of Linux, a piece of code... does it really make you that much smarter? Wait... no... from what I gathered.. you seem to only know how to change userland settings or some configurable bits which were put there by the coder without a proper UI. These are what's known as scr1pt k1dd1ez, way back when.
