[quotations]行胜于言

子贡问君子。子曰：先行其言而后从之。

[札记]考完了

high了。考完了。总结一下。

其实一门课，学习到什么程度，都是看你对自己的要求是多高。大学以前，学习很用功自然是不用说。大学时候，没有硬性的要求以后，自己对自己的要求就放松了（当然这只是一个原因），对自己的要求就是及格，自然考出来的成绩也就及格多一点。
现在读研，有点发奋图强的感觉，对自己的要求很高，不是跟大学比（从及格提高到优？），也不是跟大学之前比（跟以前一样优秀？），而是崭新的，understanding but not by comparison，一种求真的感觉，而且是满心欢喜的去追求，要求很高当然很累，但是心情是放松而愉快的。

回顾这几个学习的阶段，每个阶段学的东西都是通过不同方式学来的。大学之前，自己是被动的学习，但是自己学得倒也挺乐，不需要动脑子，因为当时就没想过不学习还能干点别的什么，专心，挺好。大学时候，成绩是差一点，但是杂七杂八地学了不少事情，吉他啊、架子鼓啊、拉丁舞啊、管乐队啊、社团啊，颓废是颓废一点，倒是过得挺摇滚（当然，是要付出代价的，你不花力气解决的事情永远不会自己得到解决，大学里面的课程我是在后面两年solitude中自学补回来的。）现在的心态嘛，是既严肃又摇滚，既紧张又放松。

成绩还没出来，也不知道考得好不好，乐啥？。这就对了，就是不管最后的成绩！你的努力是多少，你自己是知道的，你自己最清楚自己能打多少分，而不是等最后试卷上的一个成绩来判断自己。先high上了！――不管成绩多少。自己感觉这个学期就是学得不错，关键是比较用功。成绩是一个外部的标准，内部的标准只有比外部标准高以后，做出来的事情才会比预想当中的更好。

嗯。再去向下一个目标努力了！

Notes on learning

We learn things by divide, conquer, combine.

To be noted, by dividing the thing, we do not separate it from the whole. The reason we devide things is not that things are divided, but that we can only learn thing little by little. We do not accept things immediately, but by accumulating and changing. Our concepts, understanding, are formed little by little, step by step, stage by stage. So when we learn things, we should always bear in mind the whole thing -- what in the end I am learning? We study the details carefully so that we can know the whole deeply. Study the details carefully without lost the whole, while study the whole by dividing, conquering and combining.

vision, Goal, Plan, Do

Vision means you know yourself, and focus what your want most, imagine it, form the wanting, desire, passion into a picture, a seeing.
Setting a goal means you transmute your vision into specific targets.
Plan means actual, definite ways that can be acted.

The glorious DO
We may have the wrong illusion that when we have set our plan, we have finished something. In the fact, having set the plan, we start doing something, we start a journey we have chosen, and by persistent work we lead the journey to the end.
We all admire the glorious moment when the destination is reached. (That is the reason we pay all our sweat for. ) However, the destination and the goal are not separated. It is the wanting, trying and struggling in the journey that the glorious lies the meaning.

相比较第一场雪，两场雪，降雪量差不多，但是效果就不一样，这次的雪就能够积的很厚了。
第一场雪下的时候是刚到零度。雪落到地上就化了。
这次是连续几天零下七八度之后，再轻轻地悄悄地下了那么一场雪。

A glimpse in the life time

Eric Hoffer说："A man is likely to mind his own business when it is worth minding. When it is not, he takes his mind off his own meaningless affaires by minding other people's business."

当你找到一件meaningful的事情后，你就会发现很多meaningless的事情。比如，看电视剧。
今天我看见其他人在看《反恐24小时》的时候，听到电视剧里特意强调出来的时间的声音。突然意识到这是在KILLING!
It is not the killing in the show.
It's KILLING your time!
It's KILLING your time while you gladly watch it killing.

~quotation ~computing

"I think that it's extraordinarily important that we in computer science keep fun in computing. When it started out, it was an awful lot of fun. Of course, the paying customers got shafted every now and then, and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful, error-free perfect use of these machines. I don't think we are. I think we're responsible for stretching them, setting them off in new directions, and keeping fun in the house. I hope the field of computer science never loses its sense of fun. Above all, I hope we don't become missionaries. Don't feel as if you're Bible salesmen. The world has too many of those already. What you know about computing other people will learn. Don't feel as if the key to successful computing is only in your hands. What's in your hands, I think and hope, is intelligence: the ability to see the machine as more than when you were first led up to it, that you can make it more."
--Alan Perlis, as quoted in The Structure and Interpretation of Computer Programs by Abelson, Sussman, and Sussman

wiki！
有了wiki以后，想要学知识，变得容易了很多。
比如，今天看到了新闻，里面讲到IPO，不懂，查了wiki，就知道是首次公开募股(Initial Public Offerings)。
比如，听Bach，不知道"allegro"什么意思，查wiki，就知道是The musical tempo meaning "quick and lively" or, literally, "cheerful".
比如，要看Van Gogh的画，到wiki查，不但有他的画，还有他的简单传记。
还有很多，总之，对于这个"Launched in 2001, it is the largest, fastest growing and most popular general reference work currently available on the Internet."，从内心深处充满了赞叹！

[reading]Turing lectures

I probably have spent too much of my life thinking about computers, but I do not regret it a bit. I was fortunate to enter the field of computing in its infancy and participate in its explosive growth. The rapid evolution of the underlying technologies in the past 30 years has not only provided an exciting environment, but has also presented a constant stream of intellectual challenges to those of us trying to harness this power and squeeze it to the last ounce. I hasten to say, especially to the younger members of the audience, there is no end in sight. As a matter of fact, I believe the next thirty years will be even more exciting and rich with challenges.

The three principal contributors to performance in scientific processors are the algorithm, the compiler, and the machine organization. When possible, the simultaneous optimization of these three factors holds the key to the hightest possible performance.

[reading]Understand, but not by comparison

In the final analysis, it is between you and God.  It was never between you and them anyway.
-- Mother Teresa

There is a time in every man's education when he arrives at the conviction that envy is ignorance; that imitation is suicide; that he must take himself for better, for worse, as his portion; that though the wide universe is full of good, no kernel of nourishing corn can come to him but through his toil bestowed on that plot of ground which is given to him to till. The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.
-- Ralph Waldo Emerson, Self-reliance

    If I am all the time measuring myself against you, struggling to be like you, then I am denying what I am myself. Therefore I am creating an illusion. When I have understood that comparison in any form leads only to greater illusion and greater misery, just as when I analyse myself, add to my knowledge of myself bit by bit, or identify myself with something outside myself, whether it be the State, a saviour or an ideology - when I understand that all such processes lead only to greater conformity and therefore greater conflict - when I see all this I put it completely away. Then my mind is no longer seeking. It is very important to understand this. Then my mind is no longer groping, searching, questioning. This does not mean that my mind is satisfied with things as they are, but such a mind has no illusion. Such a mind can then move in a totally different dimension. The dimension in which we usually live, the life of every day which is pain, pleasure and fear, has conditioned the mind, limited the nature of the mind, and when that pain, pleasure and fear have gone (which does not mean that you no longer have joy: joy is something entirely different from pleasure) - then the mind functions in a different dimension in which there is no conflict, no sense of `otherness'.
     Verbally we can go only so far: what lies beyond cannot be put into words because the word is not the thing.

完美永无止境

当你不让你自己停的时候，你的思想是不会停的，你的努力是不会停的。只有当你让你自己停的时候，你的努力才会停下。你的脑子里会有类似这样的声音："差不多了，就这样吧"，"做到这样就已经够了"，"做这么好干吗，差不多就行了"，"已经完成任务了，多费这劲干吗"，"说不定这样就行了，多做了也白做"，"现在这样已经比大部分人强了，差不多了"。
但是，完美是永无止境的。
当你对自己说"差不多"的时候，就是你对完美说再见的时候。你在这一刻做出了选择，你选择了平庸，而不是杰出。
天才只是意味着终身努力。(Genius only means hard-working all one's life.  --Mendeleyer , Russian Chemist)
你的努力是对你自己的挑战，你的挑战的成果是给你自己最好的礼物。(The reward of a thing well done, is to have done it. -- Ralph Waldo Emerson)
一个人最大的敌人是自己。
"Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness that most frightens us. We ask ourselves, Who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? You are a child of God. Your playing small does not serve the world. There is nothing enlightened about shrinking so that other people won't feel insecure around you. We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It's not just in some of us; it's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others." -- Marianne Williamson
"少一点，但要成熟；不留下进一步要做的事情；极度严格的要求"（高斯）
每一个人的内部都有相当大的潜能。爱迪生曾经说："如果我们做出所有我们能做的事情，我们毫无疑问地会使我们自己大吃一惊。"从这句话中，我们可以提出一个相当科学的问题："你一生有没有使自己惊奇过？"――拿破仑・希尔
"Stay foolish. Stay hungry!" --The Whole Earth Catalog, quoted in Steve Jobs's speech in Stanford
"When you settle, you choose mediocrity. Don't settle for the best of the worst. Keep looking. Don't settle for something that's barely okay. Push to make it better. Don't settle for average work from others when exceptional is needed. And don't settle for delivering good when you're capable of better. Expect more from yourself. Then expect more from others." -- Don't Settle by Nan S. Russell

永无止境

看科学的发展史，问题永远没有彻底解决的一天。但是，这正是科学美丽之处。
人类的探索永远没有止境，这也正是探索的美丽之处。
永远没有彻底的、绝对的end，生命是living的，世界是living的，真理是living的。哲学把这概括为运动是绝对的。
生命是永无止境的过程。学习是永无止境的过程。完美是永无止境的过程。
即使现在的并不是最后的完美，但是在目前的条件(conditioned, see Krishnamurti's "freedom from the known")下，在目前的时间限制下，("少一点，但要成熟；不留下进一步要做的事情；极度严格的要求")做到最好。那么，这一刻是完美的瞬间；而这一瞬间也成了永恒。

[reading]discipline

...discipline is the act of the learning all the time.
-- Jiddu Krishnamurti [链接]

The root meaning of that word "discipline" is to learn; and you cannot possibly learn if you are merely conforming, or suppressing, or controlling. So one has to understand again the meaning of the word "learning". Because if there is no right discipline, the mind cannot possibly find an answer to this, the answer in which is implied the meaning, the structure, the whole of life.
     To understand there must be discipline. Please follow this a little bit; give your attention. Understanding is not the outcome of the intellect, or of emotion, of sentiment. As we said, understanding comes when the mind is really very, very quiet; has no movement at all in any direction. When you observe a tree, if you have ever done it, when you look at a tree, your mind never observes the tree; it observes the image it has created about a tree; and that image is always moving; it is never quiet. It is being added to and taken away from. It is only when the mind is very quiet, really observant, without any movement, that it observes the actual fact of the tree.
-- Jiddu Krishnamurti, Ojai 1966, 2nd of 6 talks [链接]

Nature is a discipline of the understanding in intellectual truths.

ipv6

科院宿舍连上了ipv6，有机会提前体验下一代网络，lucky。
1、网络电视，这下爽了，在寝室可以看电视了。当然，关键是清晰度和带宽。
2、下电影，3Mb/s。

网络课上说的ipv6的改进在于：
首先也是重要的，IPv6有比IPv4长得多的地址。IPv6的地址用16个字节表示，地址空间是IPv4的296倍，足以给每个人分配5×1028个具惟一性的地址。无论未来怎样发展，看来这么多的地址也是够用的。
IPv6第二个主要的改进是简化了IP分组头，它包含8个段（IPv4是12个段）。这一改变使得路由器能够更快地处理分组，从而可以改善吞吐率。
第三个主要改进是IPv6更好地支持选项。一些从前是必要的段现在变成可选的了。此外，表示选项的方式也有所不同，使得路由器能够简单地跳过跟它们无关的选项。这一特征加快了分组处理速度。
IPv6有重大举措的第四个方面是安全性。身份验证和保安功能是这个新的IP的关键特征。
最后一项重要改进是有关资源分配的。取代IPv4的服务类型段，IPv6的流标记段支持对属于一个特别的交通流（对应的发送端可能请求特别的处理）的标记，从而能够支持诸如实时视频这样的特殊交通。

目前ipv6的网站还不是很多，能搞ipv6的都是精英啊。清华、北邮、浙大、上交大……等等。

生命的意义在于实践，生命的惊喜在于想像力

生命的意义在于实践。实践：做、do、action、行、落实、执行的意思。要明白实践的重要性，先搞清主观和客观的关系：一件事情，首先被主观创造，然后是落实到客观创造。主观和客观是不可分离的。主观创造是下一步客观创造的先决条件，也非常重要，但生命的意义不在于主观创造，而在于实践创造。往往，主观创造从一开始只是确定了大致上的方向，"朦胧的"目标。这个"朦胧的"、"大概的"目标要伴随这时间逐渐实现、随着一步步的实现逐渐清晰化（也许再按照实际情况做出稍微的修改）。主观创造（目标）只完成了一个开始，从时间上说，只占了很少的一部分，而接下去漫长的实践（目标实现）的过程才是真正的生活的过程，所以从主观和实践在生命中所占的比例来说，实践才是生命的意义。爱默生说：The reward of a thing well done, is to have done it.

生命的意义在于实践，主观创造也需要一个相应重要的位置（至少一个同样重要的词汇来描述它）。那么，生命的惊奇在于想象力。主观的创造是不确定的，正是这种不确定性给生命带来了惊喜。所有的创造、进步都来自于想象力。用你最大胆的想象力去想象未来，那就是未来的样子！

[reading]freedom from the known

     In order to observe the movement of your own mind and heart, of your whole being, you must have a free mind, not a mind that agrees and disagrees, taking sides in an argument, disputing over mere words, but rather following with an intention to understand - a very difficult thing to do because most of us don't know how to look at, or listen to, our own being any more than we know how to look at the beauty of a river or listen to the breeze among the trees.
...
     It is one of the most difficult things in the world to look at anything simply. Because our minds are very complex we have lost the quality of simplicity. I don't mean simplicity in clothes or food, wearing only a loin cloth or breaking a record fasting or any of that immature nonsense the saints cultivate, but the simplicity that can look directly at things without fear - that can look at ourselves as we actually are without any distortion - to say when we lie we lie, not cover it up or run away from it.
...
     If you see the danger of your conditioning merely as an intellectual concept, you will never do anything about it. In seeing a danger as a mere idea there is conflict between the idea and action and that conflict takes away your energy. It is only when you see the conditioning and the danger of it immediately, and as you would see a precipice, that you act.
