  • when we build software for scientists, we should think about what they would do with the returned information. That’s where context is really important as well. I’ve seen too many examples where the user is offered options that make no sense for what you want to achieve.

data mining google statistics thinking

  • Sixty years ago, digital computers made information readable. Twenty years ago, the Internet made it reachable. Ten years ago, the first search engine crawlers made it a single database.
  • Google's founding philosophy is that we don't know why this page is better than that one: If the statistics of incoming links say it is, that's good enough.
  • The scientific method is built around testable hypotheses. These models, for the most part, are systems visualized in the minds of scientists. The models are then tested, and experiments confirm or falsify theoretical models of how the world works. This is the way science has worked for hundreds of years.

  • Peter Norvig, Google's research director, offered an update to George Box's maxim: "All models are wrong, and increasingly you can succeed without them."
  • Once you have a model, you can connect the data sets with confidence. Data without a model is just noise.

      That's what Chris Anderson thought is old-school.
  • But faced with massive data, this approach to science — hypothesize, model, test — is becoming obsolete.

      Come to conclusion? I don't think so.
  • There is now a better way. Petabytes allow us to say: "Correlation is enough." We can stop looking for models. We can analyze the data without hypotheses about what it might show. We can throw the numbers into the biggest computing clusters the world has ever seen and let statistical algorithms find patterns where science cannot.
  • What can science learn from Google?
  • This kind of thinking is poised to go mainstream.

  • We don't want to argue that noise is always good, it's clearly important to spend some time without it every day.
  • Filtering isn't everything it's cracked up to be, though, and you wouldn't want to live in a fully filtered world all the time. Social media noise is an essential part of learning and living on the web.
  • It's one thing to find something you didn't know you needed right now, it's a whole other skill to be able to recall information that seemed marginally useful at best in the past at a time in the future when the need for it arises. Who can't remember doing that before? The ability to recall passively collected information that was gathered purposelessly in the past and put it to use in the future is a particularly powerful form of intelligence
  • ...7 more annotations...
  • Some people call it "serendipity," others call it "passive and opportunistic information acquisition." (Erdelez, see below.) The less limited the boundaries of your scope of view are, the more likely you may be to find things you didn't even think to look for.
  • Some people worry that being exposed to too much information will lead to not remembering very much of it. Scientists say that's not necessarily the case, though.
  • Quiet time, time off-line, deep thoughts and long books are all beautiful things - essential to a healthy intellectual, psychological and social life. We argue, though, that the opposite of all those things - online social media noise, is also a great opportunity that deserves to have its worth recognized at a time in history when many of us are struggling to deal with it.
  • Serendipitous search in the offline world is believed to be one of the ways our understanding of the world expands.
  • it's an interesting understanding of the way that swimming through noise helps us become who we are.

  • Erdelez argues that when prompted about a particular incident of accidental discovery our memories are better than we might think.
  • I think what makes noise unbearable is the guilty feeling we have to not read everything. But if we takes some times to dive in the noise, without feeling guilty of what we have missed, it is just a positive habit.

  • 1、你一定要觉得你自己的问题有趣而又重要，否则你就不会有激情，不会投入。 2、你一定要有能力解决问题。假如不能完全解决问题，起码你要问自己能够做些什么。 3、除了你自己的肯定，如果还有人也认为你的问题很重要，且这样的人越多越好。
  • C代表Creative Power创造力，K代表Knowledge知识，I代表Information信息，T则是Thinking思考，Q是Quarrel讨论，L是Logic Reasoning逻辑推理，E是Experiments实验，W是Wide Field广博的领域，H则代表Hell地狱。这样看来，创造力就等价于：汇集知识与信息，然后不断思考并反复讨论，再利用逻辑推理和实验在广博的领域里积分的结果。

Key difference between Web 1.0 and Web 2.0 - 0 views

  • Roger Chen on 27 Jun 08
     
    Web 2.0 is a buzzword introduced in 2003-04 which is commonly used to encompass various novel phenomena on the World Wide Web. Although largely a marketing term, some of the key attributes associated with Web 2.0 include the growth of social networks, bi-directional communication, various 'glue' technologies, and significant diversity in content types. We are not aware of a technical comparison between Web 1.0 and 2.0. While most of Web 2.0 runs on the same substrate as 1.0, there are some key differences. We capture those differences and their implications for technical work in this paper. Our goal is to identify the primary differences leading to the properties of interest in 2.0 to be characterized. We identify novel challenges due to the different structures of Web 2.0 sites, richer methods of user interaction, new technologies, and fundamentally different philosophy. Although a significant amount of past work can be reapplied, some critical thinking is needed for the networking community to analyze the challenges of this new and rapidly evolving environment.

  • 廉價的憐憫只不過是自私的最佳盾牌
  • 亞當．斯密的《道德情感論》裏有一個出名的「中國地震」比喻，說一個普通的英國人由於距離遙遠、情感陌生，因此不會對遠在中國的地震災民生起太大而持久的同情心。對那些認為道德建立在情感之上，而情感又決定於關係親近與否的人而言，這是個經典比喻
  • 我們每一個個人的行為都可能會影響到地球另一端陌生人的生命。例如我們的消費行為就不再只是衡量個人消費能力然後購買滿足感這麼簡單了，它們可能還會影響到世界某個角落居民的生活環境。因此香港這一刻對於鄰邦史無前例的同情心，有必要轉化成一種真正具有全球公民意識的道德情感，而這種道德情感需要知識去理清我們和地球上其他人的關係，需要不斷反省的韌力，還需要行動的勇氣。要做世界公民，光有一時的同情心氾濫是不夠的。

  • 近代中国遭际惨烈，有良知的知识分子无不为之椎心泣血，再三的挫败使他们在救亡的进程中日趋激进，最终达成了一种群体性的异化：即认为要实现现代化，必须放弃民族文化。
  • 这位以激烈批评“丑陋的中国人”著称的公共知识分子，多年以前已完成了他对传统文化的破坏性使命，因此他的政治生命早已终结。对柏杨来说，莫大的欣慰也许就是一个不再需要柏杨的中国。
  • 龚鹏程注意到，二十世纪哲学流派称谓常冠有一种否定性限制词，如“反”、“非”、“否”、“拒斥”、“破”、“拆”、“无”等。这是一个破坏压倒建设的时代，就像茅盾小说里的人物所愤激大呼的那样：“一切都毁了吧！一切都毁了以后，乌托邦就出现了！”
  • ...4 more annotations...
  • 他以笔为枪，指斥“酱缸文化”，并像他的前辈一样“希望能从根本上解决这些问题”。不幸，历史证明，凡是以这种浪漫主义式的狂飙突进从根本上解决问题的，往往都挟带着非理性和暴力。柏杨属于赫尔岑一个多世纪前就批评过的那种人物：“尚未解放自己，却想要解放他人。”因此，替中国文化作病理学分析的柏杨本人，其实也是一个很好的精神分析对象。
  • 就像李普曼曾说的那样，“凡是你严重匮乏的，都是缺乏人类的权利造成的。因为这个词组越空洞，就越能指称几乎任何事情，很快就会变得能够指称差不多万事万物
  • 他的命题大多是论战式的，充满道德判断和情绪化语言，对一段乱世除了贴上“禽兽王朝”的标签外看不到其余历史价值。其否定姿态在锐意破坏的同时，也限制和误导了他的判断力。
  • 吊诡的是，柏杨激烈批判的东西，也正是其价值得以确立的东西。在一个多元权威的时代，不可能再有一个柏杨引起他当年那样的轰动；此刻反复夸张地攻击某一权威，并不能引起人们多大的兴趣

    柏杨的去世也许意味着一个时代的谢幕，人们关注他的离世，大抵也是因为某种象征性意义。这位以激烈批评"丑陋的中国人"著称的公共知识分子，多年以前已完成了他对传统文化的破坏性使命，因此他的政治生命早已终结。对柏杨来说，莫大的欣慰也许就是一个不再需要柏杨的中国。

  • His basic thesis is that when you have so much data you can map out every connection, every correlation, then the  data becomes the model. No need to derive or understand what is actually happening — you have so much data that you can already make all the predictions that a model would let you do in the first place. In short — you no longer need to develop a theory or hypothesis - just map the data!
  • First, in order for this to work you need to have millions and millions and millions of data points. You need, basically, ever single outcome possible, with all possible other factors. Huge amounts of data. That does not apply to all branches of science.
  • The second problem with this approach is you will never discover anything new. The problem with new things is there is no data on them!
  • ...3 more annotations...
  • Correlations are a way of catching a scientist’s attention, but the models and mechanisms that explain them are how we make the predictions that not only advance science, but generate practical applications. One only needs to look at a promising field that lacks a strong theoretical foundation—high-temperature superconductivity springs to mind—to see how badly the lack of a theory can impact progress
  • Anderson is right — we are entering a new age where the ability to mine these large amounts of data are going to open up whole new levels of understanding
  • This is a new tool, and it will open up all sorts of doors for us. But the end of the scientific method? No — because that implies an end of discovery. And end of new things.

  • Overall, the foundation of the argument for a replacement for science is correct: the data cloud is changing science, and leaving us in many cases with a Google-level understanding of the connections between things. Where Anderson stumbles is in his conclusions about what this means for science. The fact is that we couldn't have even reached this Google-level understanding without the models and mechanisms that he suggests are doomed to irrelevance.
  • Anderson appears to take the position that the new research part of the equation has become superfluous; simply having a good algorithm that recognizes the correlation is enough.
  • Correlations are a way of catching a scientist's attention, but the models and mechanisms that explain them are how we make the predictions that not only advance science, but generate practical applications.

    You really don't understand a concept until you know what it's made of. The taxonomy of marketing (filled with a bazillion tactics) is murky at best. The tactics are so numerous, expensive and sometimes emotional that we easily focus on the urgent instead of the important. Perhaps we could try a different approach:

  • Let’s get concrete about what I mean here. The brain is one of the most complex networks in the world, with more neurons than there are stars in the galaxy. Its hardware is a complex network of neurons; its software a complex network of memories. And so too is the Internet a network. Its hardware is a complex network of computers; its software a complex network of websites. There is a lot we can learn from the brain and it can tell us where the Internet is headed next.
