design patterns
面對特定情境，從前人經驗所歸納出來的解決方法
一種特定模式的解法

喔，我講的 patterns 指的就是 design patterns :P。
GoF《Design Patterns》p.2, 1.1 What is a Design Pattern?
Christopher Alexander says, "Each pattern describes a problem which occurs over and over again（JK 注：因同樣問題重複出現，從而歸納萃取出對症下藥的 "patterns"。） in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice."（JK 注：因為 "patterns" 只是「樣式」、「模式」、「範式」，不是針對每個具體問題的精確解答。）Even though Alexander was talking about patterns in buildings and towns, what he says is true about object-oriented design patterns. Our solutions are expressed in terms of objects and interfaces instead of walls and doors, but at the core of both kinds of patterns is a solution to a problem in a context.
只是一種解決的方法，並不像algorithm要求的如此精準~
design pattern 在不同的language中實作是不同，但是理念相同
algorithm 實作，我想，只是源碼的差異罷了
這樣子想不知對否
哈，禮拜五要去敗啦，不用太擔心
