写代码

转自这

• try to write as less code as possible.
• refactor your code often; trying to avoid duplicate stuff, improving its readability and simplifying its structure without changing its results.
• comment your code as much as possible (comments do not count as code :) )
• avoid complex code structure with large class hierarchies that are used only once and in a single path.
• do not optimize early
• do not generalize early
• try to avoid very long functions
