知识的局限性 碎片化的知识无用, 碎片化知识切割人生.
Law of the hammer.
过份相信主观能力. 看懂内核代码, 非常耗时, 困难(实现对应的signifiers 非常难找, 有些时候还有歧义, 如packet_rcv的PACKET_LOOPBACK), 费时费力不等于学到的多, 往往意味相反.
Trying harder doesn’t mean effectness. 不要感动自己, 方法不对,越努力差距越大.
Imperfect Understanding and radical fallibity are the natue of human.
Completeness, consistency, validity, soundness. – Logic

Hypothesize bravely/boldly, to prove carefully
Free from the curse of symbols

Just as the largest library, badly arranged, is not so useful as a very moderate one that is well arranged, so the greatest amount of knowledge, if not elaborated by our own thoughts, is worth much less than a far smaller volume that has been abundantly and repeatedly thought over. The difference between the effect produced on the mind by thinking for oneself and that produced by reading is incredibly great; and thus it is for ever increasing the original disparity between minds, by virtue whereof we are driven to the one or to the other. Thus reading forces on the mind ideas that are as foreign and heterogeneous to the tendency and mood it has at the moment, as is the seal to the wax whereon it impresses its stamp. Thus the mind is totally compelled from without to think first of one thing and then of another, for which it has absolutely no inclination or disposition. … Therefore the mind is deprived of all its elasticity by much reading as is a spring when a weight is continually applied to it; This practice is the reason why erudition makes most men more stupid and simple than they are by nature and also deprives their literary careers of every success. - Schopenhauer Parerga and Paralipomena Vol.2 Chapter XXII

The Archaeology of Knowledge
Leave questions open
there are always some knowledge which is very complicated to understand and we should leave them alone.
I have never thought about questions that are not real ones - I have not squandered myself. – N
5 Ego and body
Don’t limit yourself. Don’t be paranoid. Don’t get religous about specific programming skill.
I know I will be lost and confused in my whole life.

Chapter 6 section 1: 记忆还依赖于人的已有的知识结构,只有当输入的信息以不同形式汇入人脑中已有的知识系统时,新的信息才能在头脑中更好地巩固下来。
Retrieval and Repeat
精细进行复述是存储信息最有效的方法,它是指把要记住的内容和已有的知识经验联系起来。存储是信息编码和提取的中间环节,它在记忆过程中有着重要的作用。 - 普通心理学 Chapter 6 section 1
Think for yourself
Don’t start from the pure conceptions, from the real basic problems. Problems before conceptions.
All by themselves my eyes put an end to all bookwormery, otherwise known as philology: I was released from the ‘book’, and read nothing more for years—the greatest favour I have ever done myself!That nethermost self, as if buried alive, as if made mute beneath the constant need to pay heed to other selves (—which is what reading is!) awoke slowly, shyly, hesitantly—but finally it spoke again. I have never been so happy with myself as in my life’s periods of greatest illness and pain: you need only take a look at Daybreak or The Wanderer and His Shadow to understand what this ‘return to myself ’ was: the highest kind of recuperation!… The other kind simply followed on from this. –Human, All Too Human With Two Continuations
What did Richard Feynman mean when he said, “What I cannot create, I do not understand”?

7 Forming mind structure over change/time
Plain worldview; learning by doing

Question-based thinking not Solution-based thinking.
看别人的实现, 不仅不能学到知识, 更为糟糕的是破坏了自己的创造力.
Vicariousness!!quick understanding, no complex brain labors, it’s easy. But it also brings fake.
“记录在纸上的思想，不过是像在沙上行走者的足迹而已，我们也许能看到他所走过的路径；如果我们想要知道他在路上看见些什么，则必须用我们的眼睛” - Schopenhauer
事实 我们要实事求是，现在像贴贴标语，什么打倒田中义一等，都仅务虚名，像豆腐店里生意不好，看看“对我生财”泄闷一样。又像是以前的画符，一画符病就好的思想。贴了打倒帝国主义，帝国主义就真个打倒了么？这不对，我们应做切实的工作，奋力的做去。 – Hu Shi
How much we understand the world isn’t better than how well.

观看阅读别人创造的现成的内容, 能让人短暂的知道哪些东西是怎么实现的, 却不能让你获得创造那样内容的能力. 即便是看似最简单基础的内容都无法理清. – Wang Yin
Take the programs, modify them and enhance them. –Stevens
