Through this reading "from small specialists to work," the book, I realized the importance of the blackboard. Blackboard, the information given may be pictures and text, we can learn about information, coupled with our own findings, we might accept a different training, different levels of educational background and professional experience, different views and so on. However, we are keen to write the code's heart is the same.
Avoid programming by coincidence, sometimes a very lucky coincidence of the word, but it still will bring misfortune. So we have to deliberate programming, always know what you are doing, do not blindly programmed to act in accordance with the plan, relying on reliable things, to establish their own assumptions document, do not just test the code, but also to test assumptions, prioritize, do not slaves of history.
Reconstruction of us is very important. Rewrite, redo, re-structure the code together called remodeling. Because the code is not static, it needs to evolve. We should repeat, non-orthogonal design, outdated knowledge, when reconstructed improve performance.
