I m up in the middle of the night..seldom awake at this time, it is 3 + a.m now..Almost 4...
Not really studying wholeheartedly .. weird huh? Anyway, I'm not feeling very sleepy yet, that's y i'm still awake at this time.. Looking through those examples of my programing and reading some theories of the PCD. In boredom, here I'm to leave some footprints.. ^^
