Articles, Tutorials and Talks

"Which functions should go into which modules? How does data flow through the project? What features and functions can be grouped together and isolated? By answering questions like these you can begin to plan, in a broad sense, what your finished product will look like."




看起来很土的决策, 到后期才能发现是良心...
