i must thanks the man, Fu-Kwun Hwang for his worthy of noble prize forum for informal learning cum community of practice CoP.

My thoughts:
so after i am done remixing it, i will also release it's remixed it's source code back, there by guarantee your freedom to share and change free software--to make sure the software is "free to change" for all its users.
