参考psychology.
知识不应是概念游戏, 而应该具有生命力, 是生长出来. “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
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.
不要成为跑马场, 叔本华晚年整理的论文杂集《附录和补遗》里的《论思考》第4节 别人的跑马场. or in 叔本华美学随笔.
Think for yourself.
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

Fallacies

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.
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.
不要以为看懂内核代码, 有多了不起. 只要肯投入时间, 谁都能看懂kernel代码, 但是这样值吗?
看内核代码实际是个查找搜索的过程, 及其耗费时间. 收获的只是一个点. 非常不值. 必须要衡量投入产出比. 要看内核实现, 必须要先, 评估能学到什么.
* Trying harder doesn’t mean effectness. 不要感动自己, 方法不对,越努力差距越大.

你有什么值得分享的高效学习方法? - 高冷冷的回答 - 知乎

Encoding

Storage

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

复习是学习之母。”每一本重要的书籍都必须一气呵成连续读上两遍。原因之一是在阅读第二遍的时候,我们会更好地理解书中内容的整体关联,而只有知道了书的结尾才会明白书的开头;原因之二就是在第二次阅读的时候,我们的心境、情绪与在第一次阅读时已经有所不同。这样,我们获得的印象也会不一样。情形就好比在不同光线之下审视同一样的物体 –论阅读与书籍
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

Principle

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

Think for yourself

时间花在别人的实现上, 就没有自己的实现了.
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
