A checklist for adding a new variable to a program
We're programmer's. We code. We spend our time implementing stuff - making it do this, or making it do that.
Well, one of the first things we need when beginning the implementation of a new feature is variables.

[font=arial][color=rgb(40,40,40)]An interesting article about the game Gamedev Tycoon, and what the development team did as a pre-emptive strike against game crackers.
The sad thing is the part about 97% downloading the crack instead of buying.

an interesting read.
as can be seen from the article, the traditional c++/oo way of organizing code can be inefficient, depending on implementation.
in the article, they refactor into a more component type architecture (arrays of component types vs object components contained in the object instances)…
