Man that makes me jealous

This is interesting because it reminds me a lot of problems in social media

• it shows the complex behavior of how people commenting on popular social media, and how differently it works from conventional plain commenting systems.
• It's getting boring if more people began to realize it consciously or unconsciously, once everyone began to follow this flowchart, the content will suffer homogenization, what makes reddit original, worthy reading and valuable will be gone
• The upvote and downvote button exist because it was designed to replace silly '+1' like comments, but soon people discover other usages, for example downvote would be abused to express disagreement while it originally means mark as spam or inappropriate, people would like to upvote more pun without thinking, there's whole category of karma abusing, like karma whoring, upvote party, a comment may get upvoted by simply saying "beacon!". Use upmod and downmod to simulate a voting system, etc. An ID's corresponding karma is more meaningless if more upvote abuse is conducted. People's behavior is out of design scope. The vote button even acts like a placebo button, people would upvote something simply think they can magically mark it as read.
• Upvote blindness. One is likely to upvote simply because many other people upvoted it, if you don't understand half of the comment and the commenter seems to like know what he is talking, you are likely to upvote it no matter you know the actual truth or not. HN once tried to show points after voting, but it wasn't quite successful.
• Eternal september. Proggit sufferes eternal september every year, because the submission quality downgrades eventually, so old users are more selective to read and reluctant to upvote. But newbies are very enthusiastic to upvote and downvote. So lots of stupid AskProggit are more likely to popup because newbies all have the similar problem, nevertheless the problem itself is rampant and answers can be easily found on other sites like stackoverflow.
• The FAQ won't work. Technology changes fast, newbies are likely to looking for the lastest, interactive and live answers from individuals, FAQ helps, but it often fails because it's not kept updated. And people are likely to select authority advices from multiple places , a question may be asked a millions times but a self-submission may be post because of one most simple motivation: let's ask proggit and see what proggit thinks.
• People hates self posts, because reddit was designed to be a 'social bookmarking tool'. They newbie's stupid question spamming my bookmark is not an good idea. But sometimes a redditor's answer to those stupid questions turned out to be extremely useful and insightful, and fresh. It's a pity to let a wittyful comment buried, it's hard choice but you had to upvote the whole thread anyway.
• Spam filter never works well. Some submission may not interest all but perhaps helpful to a lot of people. But they get downvoted before anyone spots it.
• To design a really effective and predictable system, a equilibrium or fixed point has to be found from social media participants' behavior.

看了部纪录片 BBC.The.Secret.Life.of.Chaos ，几段话值得摘录。

Turning太伟大了，没想到在生物和化学上的造诣那么高

This is a film about one very simple question. How did we get here?

The natural world really is one great, blooming, buzzing confusion. It's a mess of quirky shapes and blotches. What patterns there are, are never quite regular, and never seem to repeat exactly.

but math & science do. e.g. the triangle are always the same, with same property. the atoms are universally the same)

But code breaking was just one aspect of Turing's genius. Just one part of his uncanny ability to see patterns that are hidden from the rest of us. For Turing, the natural world offered up the ultimate codes. And over the course of his life he'd come tantalisingly close to cracking them.

And he had realised that there was this possibility that simple mathematical equations might describe aspects of the biological world.
and later in Turing's life, an even more radical idea. The idea that a simple mathematical description could be given for a mysterious process that takes place in an embryo. The process is called morphogenesis, and it's very puzzling. At first, all the cells in the embryo are identical. Then, as this footage of a fish embryo shows, the cells begin to clump together, and also become different from each other.

Morphogenesis is a spectacular example of something called self-organisation.

The Chemical Basis of Morphogenesis - The sheer chutzpah of this paper was staggering.

like Alan Turing, Mandelbrot had a gift for seeing nature's hidden patterns. He could see rules where the rest of us see anarchy. He could see form and structure, where the rest of us just see a shapeless mess.


In essence, Turing's equations described something quite familiar, but which no-one had thought of in the context of biology before. Think of the way a steady wind blowing across sand creates all kinds of shapes. The grains self-organise into ripples, waves and dunes. This happens, even though the grains are virtually identical, and have no knowledge of the shapes they become part of. Turing argued that in a very similar way, chemicals seeping across an embryo might cause its cells to self-organise into different organs.

沙丘的比喻太深刻了！

So, an area where mathematics had never been used before, pattern formation in biology, animal markings,

里面提到的BZ reaction，没想到居然也是self-organize的一种啊。赞啊赞

chaos理论四位开山祖师：Turning, Belousov, Lorenz, Mandelbrot

才反映过来纯self-reference也是一种void啊

一篇充满杯具的帖子 It Is Now Mathematically Impossible To Pay Off The U.S. National Debt

So the bottom line is this....

#1) If all money owned by all American banks, businesses and individuals was gathered up today and sent to the U.S. government, there would not be enough to pay off the U.S. national debt.

#2) The only way to create more money is to go into even more debt which makes the problem even worse.

You see, this is what the whole Federal Reserve System was designed to do. It was designed to slowly drain the massive wealth of the American people and transfer it to the elite international bankers.

It is a game that is designed so that the U.S. government cannot win. As soon as they create more money by borrowing it, the U.S. government owes more than what was created because of interest.

简单的用中文描述一下，美联储掌握在私人手里。这个美联储的成立的设计目标，fractional reserve banking，就是让联邦政府连利息都还不清。dollar system挺有意思的。

最后提醒一下这篇文章扯谈居多，切莫当成真正的技术贴看待。。。。

1. 西伯利亚 是 鲜卑利亚 音译。传说中鲜卑起源自黄帝之孙曰始均。《晋书》记载：曾在晋代受封为“鲜卑都督”的慕容廆， “昌黎棘城鲜卑人也。其先有熊氏之苗裔，世居北夷，号曰东胡。”有熊氏，就是黄帝部落。汉族有很大一部分就是由以前的鲜卑族人组成的。五胡乱华最开始是匈奴跟羯族人在闹腾，后来慕容鲜卑入主中原收拾残局，西晋末年不少汉族士大夫避乱辽东，慕容嵬父子吸收这拨人，算是五胡里面汉化的很快的了。后来鲜卑拓拔部入主中原之后，更是加速汉化，南朝陈庆之北伐之后感叹“衣冠人物，尽在中原”。鲜卑进入中原而且迅速汉化，使得北方由割据和战乱转向稳定。今天五十六个民族之一的 锡伯族 的大词典转写就是Sibe，西伯利亚的英文写法是Siberia。（说到这里，est觉得中国自古以来就是一个移民国家，如果硬是要争狭隘汉人纯血统论，那么最好就说 鸣条之后，已无华夏 了。）
2. 印度从来没有对阿克塞钦（Aksai Chin）——这是从公元六世纪流传至今的突厥语地名，意思是中国人的白石滩。Chin者，秦也；Ak则与Kara相对，比如土耳其人把地中海叫做Ak Deniz，意为白海——行使过主权，仅仅靠英国殖民者在地图上划了道线，不是照样可以声称它是印度固有的不可分割的领土吗？

拼接出来字符串 "eval"，如何把 "eval" 变成 eval() 呢？方法是

[]["sort"]["call"]()["eval"]

其中 []["sort"]["call"]() 等于 [].sort.call() ，等价于 window，所以上面 []["sort"]["call"]()["eval"] 就等价于 window.eval。

然后就是体力活了，把码表对应转换成 eval("blah blah") 这种形式就可以执行任意代码了

不同浏览器的码表不一样。Chrome和Firefox的index就不一样。

其实这个码表还可以通过 toLocal*() 函数族扩展到Unicode，比fromCharCode要简短 :D

这种flow的感觉我不是很确定，但是我想这就是一种所谓的巅峰状态。我记忆中只有初三学英语和高二学解析几何才有这种状态。其余的人生都是磕磕碰碰坡坡坎坎的。哎。

Flow在学习中的应用叫Overlearning：

Overlearning is a pedagogical concept according to which newly acquired skills should be practiced well beyond the point of initial mastery, leading to automaticity. Once one has overlearned a task, one's skill level is higher than the challenge level for that task (see Control region in the graph).

这就是传统做法里的数理习题增加熟练度吧。

与此相反，语文的学习却倡导一种“先背后理解”的作风。我把这种做法叫做 下载式。

Found this fascinating post from phi_of_sci

One of the fascinating things about the Godel incompleteness results is that infinity itself is not the problem. In some systems of arithmetic you can believe you can count to infinity and still be complete and consistent. Some even include the infinite set of induction axioms

Yet the incompleteness problem is not even due to multiplication alone. A system with all of Peano's axioms apart from addition, but inclusive of multiplication was shown by Thorlaf Skolem to be complete. The completeness problem derives from the combination of addition and multiplication on variables. These operations together provide the ability to construct the Godel numbering by allowing the definition of the unique prime factorisation of every integer and the mechanism by which Godel's unprovable statement can be constructed.
So we have yet more demonstration of how easy it is to skirt Godelian incompleteness. The Godelian incompleteness results are really about carefully choosing the formal language concepts we use to describe systems we wish to use. The real problem faced by humans is not even Godelian-incompleteness, its computational complexity. Even solving relatively small problems of Presburger arithmetic takes impossibly large amounts of time.

我也一直觉得twitter和facebook没什么。今天发现了一个惊人的数据：

Twitter官方博客宣布每日发帖量超过5000万条

人们对大量数据的形象理解能力是非常有限的。这里有个数据对比一下就知道了

By contrast, Google was averaging 400 million search queries per day in 2009.

2009年Google平均每天有40000万次查询。

也就是说，twitter在以Google索取信息1/8的速度创造信息

无论如何这对Google都是一个很大的压力。

再来一个数据，Life is RPG里说，V > T。什么意思？Facebook上FarmVille的用户数比Twitter用户数还多。。。。。。

还有在美国，Facebook的PV已经超过Google了。

如果我是Google我也会如坐针毡的。

这也很容易理解Google为什么孜孜不倦的推出Friend Connect, Open Social, blah blah，甚至以伤害Gmail为代价推出Buzz等等一个又一个失败品了。

但是我很讨厌Facebook和Twitter。正如HN上评论说到，互联网服务应该是 de-centralized 的，如果是 centralized ，很容易就被 censor 或者挂掉。唉。

豆瓣改版了。果然开始微博了。

在这个微博山寨满大街的时代，我只能感慨人们的想像力和创造力的匮乏。

Twitter官方界面/API只能显示最多3200个tweet，所以只能在和twitter的官方GTalk机器人之间的聊天记录里找了。严格的来说，这不是我的第一个tweet，这只是激活GTalk机器人的验证码，我相信在此之前我还在web发了test。但是这是我能找到最早的twitter记录了。

俺疯狂twitter的时代，twitter还有个GTalk机器人；阿娇还是处；俺还没挂过科。。。。囧。。。我就是在SXSW 2007那个春夏之交接触twitter的。。两年两个月后彻底放弃了twitter。

也感慨下，这么多年变化真大。时间过得好快。

boingboing爆出来ACTA "internet enforcement" chapter leaks

一开始还不怎么注意，后来发现这事情挺严重的。ACTC是美国、欧盟执委会和日本（后来还有瑞士、澳大利亚、加拿大、欧盟、约旦、墨西哥、摩洛哥、新西兰、南韩、新加坡和阿联酋加入）之间的知识产权保护协议体系，我不知道internet enforcement这个chapter这是proposal还是已经是成文的agreement，如果这玩意儿被通过并开始执行了有以下严重后果：

• That ISPs have to proactively police copyright on user-contributed material. This means that it will be impossible to run a service like Flickr or YouTube or Blogger, since hiring enough lawyers to ensure that the mountain of material uploaded every second isn't infringing will exceed any hope of profitability. ISP要对用户产生内容进行过滤和检查
• That ISPs have to cut off the Internet access of accused copyright infringers or face liability. This means that your entire family could be denied to the internet -- and hence to civic participation, health information, education, communications, and their means of earning a living -- if one member is accused of copyright infringement, without access to a trial or counsel. ISP可以以版权保护名义不经过审判和裁决，直接切断用户互联网连接
• That the whole world must adopt US-style "notice-and-takedown" rules that require ISPs to remove any material that is accused -- again, without evidence or trial -- of infringing copyright. This has proved a disaster in the US and other countries, where it provides an easy means of censoring material, just by accusing it of infringing copyright. 全世界必须按照美国的“通知——下架”模式来实施版权保护
• Mandatory prohibitions on breaking DRM, even if doing so for a lawful purpose (e.g., to make a work available to disabled people; for archival preservation; because you own the copyrighted work that is locked up with DRM) 禁止破解DRM

ACTA太操蛋了。

下面的第一个回复

I don't know enough about the OP to talk directly to your problem, so I can only share a few interesting frames of mind that I have picked up along the way that help push me along.
There is a phenomenon from child psychiatry that has shown that parents that say to a successful child, "Wow, you're so smart" undermine that child's ability to muscle through tougher challenges later on in life. These kids believe they are intrinsically better than their peers, so they don't keep putting effort into themselves. Eventually they encounter a challenge that exceeds their initial abilities and they give up since they don't understand their performance is in their control, not baked into their God-given make-up.
Parents who instead say, "Wow, you put in a lot of effort," teach their children that the success is based on factors that you can control, like how much effort you put in and how prepared you are and what you do. These kids do a lot better in life.

Your problem description (high IQ, creative asset, character flaw) is in the wrong frame. Since we're talking about action, it's not about who you are, but what you do.
Anyway, getting things done is surprisingly simple (not easy). You look at the goal, work backwards thinking of all the things that have to get done to get to that goal, and then start doing them.
Another key part of being successful is to delay gratification. People who need constant positive feedback to keep moving forward don't get very far in real situations since most of life is a slog on the way to a better destination.
http://www.newyorker.com/reporting/2009/05/18/090518fa_fact_lehrer
The final thing that helps motivate action is to know where you want your life to lead. It helps give each smaller project a sense of purpose: does this move my life forward or not? If it does, it's easy to step through things.
Once you have a vision, it's important to continuously repeat in your head all the positive aspects of success. A lot of people focus on the failure or ever the fear of success. As I mentioned above, most real life projects are a grind on your energy and your emotional state. You have to be your own emotional support system.
I liked Steve Jobs commencement speech at Stanford where he acknowledged how death is a motivator. Life is short. It takes a long time to accomplish anything (5 years or more). So, you only get so many chances (maybe 10) to do something meaningful. You have to always ask yourself, "Am I living this day as if it's my last?"
http://news.stanford.edu/news/2005/june15/jobs-061505.html
I will say none of these approaches to life are intrinsic to a person. I suspect all successful people have to teach themselves these strategies along the way and they struggle with them the whole way along.

这个点中要害了。我们平时完成一个project的时候，人们往往会称赞你聪明，这个project的结果很漂亮。但是问题就出在这里。我们去完成一个project的关键不是聪明，也不是结果，而是过程。如果我们接受了这种赞许，不会对我们造成直接的影响，但是我们着手做下一个project的时候，我们首先会预测这个project的结果是不是漂亮，而且我们潜意识就会想，嘿，又有一次展示我聪明的机会来了。

这样，无意中，我们做project的动机就是完全面向玩弄自己的聪明了。而其实要做完一个project最重要的是你的付出和坚持。当你没有能做到付出和坚持，那么这个project也就很自然fail

就好比说我们的聪明只是办事效率，导数大，初值高而已。但是要达到最终结果还是得靠坚定不移的effort。

里面还提到父母鼓励孩子的方法和技巧，我觉得很重要。

其实做事很简单（但是不容易），确定了目标和方法之后，这个过程就是无聊的grind。就像MMORPG里打怪一样。

其次关键是delay gratification。这一点我觉得可以再深入一下，就是庞加莱和海明威的潜意识思考法。当你做得很high的时候，不妨停一停，让你的各种思绪跟上你最尖峰的节奏，而且有助于你的休息。这个其实是有助于提高你的整体productivity，而不是去追求一个peak performance。

里面提到的positive feedback很有意思。现在很多农村的孩子觉得读书无用，我觉得这就是缺乏一种instant positive feedback的结果。其实城市里的孩子也一样，只是他们多了一个peer competition而已。这也可以很好的解释为什么很多中学里成绩拔尖的人心理都比较变态。

最后的关键就是goal。我觉得这里的goal不仅要在action中间随时提醒自己，在最开始计划一个project的时候也要考虑周全。有的project看似很好玩，其实做下去是个无底洞，或者很容易就过时被抛弃的工具。这些project是不值得做的。在一个project里fail对自己的伤害比懒惰更大。

下面有人继续针对第二条constant positive feedback进行了展开

My way of addressing this, since the real world doesn't often provide it, is to provide it for myself. For instance, I had to read 2 chapters in my Number Theory book today. I told myself that after each chapter I would let myself read HN for 15 minutes. Now there is positive reinforcement.
Another trick that helps me stay focused is to make lists. I find joy in the simple act of crossing an item off a list.
So to finish a project break it down into simple concrete tasks, and come up with some sort of simple reward for each task finished. Make sure though that your definition of success is actually achievable and dependent on factors you control. After this, get to it, and finish that project!

任务的分解和增量小规模激励也是一个很有用的方法。这里分辨了两种project，一个是能够一下子做完的，一个是不能一下子做完的。根据实际情况要多做准备和打算。

There's a reason TDD and agile are approaches programmers generally enjoy more, and it's because you get positive feedback early. The success of these techniques are only partially due to their inherent ability to adapt to change: it's also the fact that the people using them are inherently happier because they get this re-enforcement they are going down the right path and making progress.

说道这里我又想起了船夫们喊号子。。。。。。节奏性的鼓励，甚至直接把工序做成一种艺术过程，这也是提高生生产力的一个方法吧。

继续摘录一些有意思的回复

Edison also had teams of people working for him, to do the laborious tasks, a strategy the OP might want to... employ ;) hire people... I just had that problem... I couldn't finish any project, but I knwe how to do everything... I hired people, tell them how to work, micro manage them... and all I can say is that I'm quite successful... Stop trying to do all by yourself... you are too valuable to spend time actually doing things...

很不错很经济实惠的手段

Your IQ is not relevant to your ability to complete projects. It is possible your feelings about your high intelligence is a problem in that it keeps you from being willing to experience failure. These fears should dissipate as you incrementally do complete projects.
Diligence > Intelligence.
Thomas Edison: 1% inspiration, 99% perspiration.
as Tesla said, if Edison had been a bit smarter, he wouldn't have had to sweat so much.

暴笑 lol

stop at a point where you know exactly what you need to do next. It's much easier to come back when you do this.

find something that people can pay you for. Money is a hell of a motivator.
have a targeted customer/user. You will feel you cant let them down.
try to have it be something that you yourself would use. it will force you to finish the project.

这里是feedback的一些具体技巧。大学里找MM一起去上自习就是一个很强大的学习动力。说道这里我应该认识到竞争和游戏的极大促进作用。

有人提到了一种和GTD类似的时间管理技巧，叫Pomodoro Technique

all we really need is someone to talk to

英语中这句表达方式很迷人

The Cult of Done Manifesto

1. There are three states of being. Not knowing, action and completion.
2. Accept that everything is a draft. It helps to get it done.
3. There is no editing stage.
4. Pretending you know what you're doing is almost the same as knowing what you are doing, so just accept that you know what you're doing even if you don't and do it.
5. Banish procrastination. If you wait more than a week to get an idea done, abandon it.
6. The point of being done is not to finish but to get other things done.
7. Once you're done you can throw it away.
8. Laugh at perfection. It's boring and keeps you from being done.
9. People without dirty hands are wrong. Doing something makes you right.
10. Failure counts as done. So do mistakes.
11. Destruction is a variant of done.
12. If you have an idea and publish it on the internet, that counts as a ghost of done.
13. Done is the engine of more.

前面提到了要分辨一个project是否能被一下子搞定。这里有位回复了如何去做一个长达几个月甚至几年超长大型project

1. 不要一开始就被一些障碍和难题搞郁闷了。就像马拉松一样一开始不要去拼命冲刺。
2. 任务的分解。这一条被很多人反复提到。也是很多背单词方法论里重要的一点。我想这为了避免despair这一点是很重要的
3. 每天习惯性在一定时间总结当天成就和所处位置
4. 奖赏和激励的feedback
5. 关掉浏览器。不要为其他可有可无的事情分心

ENTP, ENFP, INFP, INTP等性格不同的人也可以采取各自独特的方法（Temperament Theory）。可以来这里测试。做这个测试我很纠结，因为很多事情都是我曾经没有仔细考虑过的。有的答案我两者兼有，甚至交叉。不好选择。我的结果是NTs - Rationals/ Conceptualizers (INTP, ENTP, INTJ, ENTJ)。很有可能就是INTP

Many INTPs are a lot like the stereotypical absentminded professor -- dawdling, distracted, and forgetful of mundane chores, late for obligations, losing homework or library books, and generally disconnected from the business of life in the external world...A big problem for INTPs is that they are so quickly bored, and once their attention wanders, they will rarely finish the many interesting projects they start.

继续，有人说他的毛病更大，断网都没法治。他说应该做 attention medication

At the risk of being accused of "cheating", I recommend attention medication. I am very smart, and did exceptionally well in school, but found myself unable to take even "start small" tasks to completion when not faced with an absolute, completely immutable deadline (and even then, I still handed in papers days late). I tried methods found in books, tried adjusting diet and routine, tried altering workplaces, went as far as trying to do work without an internet connection (!) -- nothing. This had nothing to do with motivation. I believed strongly in open source software, and loved to code small projects, but never finished anything. I enjoyed writing, and tried no less than 5 times to start a blog. I started building electronic circuits like headphone amplifiers but abandoned them halfway through soldering. No matter how much I wanted or tried to get stuff done, it just wouldn't happen.
A year and a half ago I started taking Vyvanse, which is essentially a slow-release amphetamine salt compound. Since then, I've completed an excellent and productive internship at Apple, shipped two major releases of Quod Libet (an open-source music library application), and am actually making progress on a sprawling thesis, three things I would never have imagined being able to do before. I've even seen a difference socially (I can have conversations that are important to others but meaningless to me without getting bored) and emotionally (I no longer feel like a failure or a waste of potential).
Other people have posted many great suggestions, and by all means, try them. But also talk to a qualified psychiatrist that you trust.

这个Vyvanse就是下面的

ADD meds (Attention Deficit Disorder)。。。。好囧。。。

后面的回复就没看了。太多太长了～～～～～～

小时候总结的resources + skills + attitude，我发现attitude这个东西有的时候是害人的。过于注重调整attitude会让你迷糊和自以为是。调节attitude是在高压迫不得已情况下的一种自我调整的手段。这样做事很牵强，很容易疲劳，人也很容易老化。甚至attitude最终被tweak成一种belief，这下就彻底脑残了。

More from the author Yang Young Soon

from LifeHacker via reddit

Frankly, I'm worried about libraries -- not because I think e-books will replace their dead tree counterparts specifically, but rather because the library as an institution is an anathema to today's notions of intellectual property. It's a loophole left over from a more permissive and libertarian era.
As an example of how much people's perspectives have changed, a few years back on Slashdot there was an article about DRM where the story submitter indicated that he had found a good use for DRM: electronic libraries. DRM in e-books could be used, he suggested, to enforce check-out periods and late fines. There was broad agreement from the masses, who were overwhelmingly tech-savvy and anti-DRM.
And then someone pointed out, insightfully, that the whole reason libraries had check-out periods and late fines in the first place was because of inventory limitations, i.e., scarcity. With only limited copies of a book and many more people wanting to read it, forcing people to return it in a timely manner was a requirement, not an ideal. Fines were not created to fund the library, which is a government subsidized institution -- they were created as a punitive measure, to encourage people to return books they had checked out so that others could read them.
In an e-library, such measures are stupid -- you have a system where scarcity no longer matters, where me checking out a book can't possibly keep anyone else from reading it.
See, this is the thing: libraries are socialist and subversive, and always have been. The media companies have always vehemently opposed them conceptually. Why should any member of the public be able to walk into a public library, obtain (for free) a library card, and borrow -- share -- something that they didn't pay to create?
They didn't like them in the 19th century and they don't like them now. But the dead tree library is an institution that dates back to antiquity -- so killing it was never a politically viable thing to do.
Because really, the natural modern analog of the library is government subsidized Bittorrent. People sharing information and knowledge without thought of profit -- for the common good.

上个世纪看popsci就发现日本人用喷墨打印技术做出来世界最小的直升机，当时很是震惊。十几年没关注这玩意了，现在Quadrotor已经足够流行了。自从上次那个iPhone遥控直升机开始就比较关注4轴/更多轴的遥控直升机了。

IEEE Spectrum最近有报道

最近一次看到比较震撼的还是来自德国人。vimeo视频：

MikroKopter - HexaKopter from Holger Buss on Vimeo.

可以载重1kg的可乐。。。很不错了。。。

上面这个六轴遥控直升机也是来自MikroKopter项目。我似乎以前在exoweb的周末黑客聚会上看到过这个MikroKopter的介绍。可惜现在找不到了。。。

Well to be honest I pondered about this topic for a while and here are my conclusions:

Types of passion:

1. Goal, passion to complete
2. Peer, passion to compete
3. Life, passion to survive

Now the original article says

1. passion for nothing
2. passion for one thing
3. passion for everything

People with a passion for everything are not interested in things themselves, they’re interested in interest.

The 3rd category is particles in the beginning of an explosion, 2nd is the flying out splashes, 1st is the long dead ones. It's funny because my observations is based on statical, scalar behavior of passion, while the author is more time-oriented and a vector field, which is what the true passion is about.

Mine is too informal :(
