刚翻完chapter1，贴点有意思的
Those who do not understand Unix are condemned to reinvent it, poorly.
-Henry Spencer
Senior engineers develop huge bodies of implicit knowledge, which they pass to their
juniors by (as Zen Buddhist put it) "a special transmission, outside of scriptures".
Robert Metcalf (the inventor of Ethernet) says that if something comes along to replace Ethernet, it will be called "Ethernet", so Ethernet will never die.
-Ken Thompson
Binary-only applications for other operating systems die with their birth environments, but Unix sources are forever.
Throughout a Unix system, easy things are easy and hard things are at least possible.
Rule 5:... Data Structures, not algorithms, are central to programming.
-Rob Pike
The most powerful optimization tool in existence is the delete key.
这个批评是针对microsoft的？：
Design rigid, closed software that won't talk to the rest of the world is an unhealthy form of arrogance.
最后的大图K.I.S.S.

Chapter4 Modularity
（chapter2和3没什么好摘的）
very small and very large modules are associated with more bugs than those of intermediate size.
下面这句其实是书里面引用别人的。
Do one thing well.
下面这句话深有体会
Repetition leads to inconsistency and code that is subtly broken, because you changed only some repetitions when you needed to change all of them.
Complexity is a cost; don't pay it twice.
Formalization often clarifies a task spectacularly.
…That simplicity came from trying to think not about how much a language or OS could do, but of how little it could do --- not by carrying assumptions but by starting from zero.
One of the lessons Unix programmers have learned over decades is that glue is a nasty stuff and that it is vitally important to keep glue layers as thin as possible.
这段关于面向对象的评论似乎有点愤世。
The OO design concept initially proved valuable in the design of graphics systems, GUI, and certain kinds of simulation. To the surprise and gradual disillusionment of many, it has proven difficult to demonstrate significant benefits of OO outside those areas.
All OO languages show some tendency to suck programmers into the trap of excessive layering.
这个才是重点。
Unix programmers know when not to use OO; and when they do use OO languages, they spend more effort on trying to keep their object design uncluttered.
