Graduation design finally arrived in the end, it is also the most difficult step. Previously envisioned (here "fantasy" more sticked to some) a "beautiful" architecture gradually collapsed in realization until it was teared to break. Experience is lacking, consider no circumference, emotion Impetuous, covering some of the lazy FIX BUG, leading to a thousand holes throughout the system, even if you use the Torpedo area. It seems to be carefully designed a set of demo processes, showing its powerful, let BUG sleep in my hand. ^ _ ^ Continue to work, and completed as soon as possible!
