Comments tell all

It was quite frustrating to see the huge differences in how people leave their comments on products they bought from B2C sites such as or Amazon. Take books, for instance; most of the comments on were words mentioning the quality of the printing, the price they got, or how fast the delivery was. I don’t recall anyone talked about how they liked the book or questions related to the reading itself. On the contrary, most of Amazon’s comments (not to mention the, which is dedicated as a reader’s club) were focused on the critic of the book or debate (sometimes quite heated, though). I wonder why this is the case…until I recall classic “self-deprecating” messages on many Chinese camera fan forums, people left remarks on German-made cameras with repeated exclamation but only a few words, “German flavor (德味, Dewei),” “Poisonous (毒, Addicted),” guess there is still a long way to go for us to understand not only how to enjoy art, literature, music, etc., but also how to express and discuss with others.

On a side note, I re-started reading SF novels after reading (again) the three-body problem trilogy. Hats off to Liu Cixin. You are a hero!


好吧,Behavioral Economics是这学期灰常有意思的一门课,包括需要读的Richard H. Thaler的Misbehaving这本书,还有Daniel Kahneman的Thinking fast and slow… 两位作者都是Noble Economics Prize winner…

我们的Prof. Eric Johnson在讲到fairness的时候给我们看了下面这段视频。。。看看我们猴子是如何看待公平这个问题的吧,特别是旁边另外一只猴子做同样的事情可以吃到🍇,而自己只能吃到🥒的时候。。。



Watching YouTube for “City Walk/Drive”

最近发现这样一种youtube video,没有对白,没有情节,有的只是一个人走路或者开车,拍摄一个城市或者一个街区在那时那刻的一切。No friction, no actor/actress, no conversation.

感觉很适合大脑放空,也适合很想念某个地方的时候回忆一下那里的感觉。It’s kind of video tharepy.


刚才在看某个东京walk video的时候还看到有人留言blame China for the COVID-19… Speechless and so sad…

It’s the inevitable result of globalization, everyone benefits from it before the pandemic, so please fight against it instead of blaming one country…


Capital Market的Prof. 很有意思地介绍了各种他常用的网站,其中一个现在一直会用的就是ycharts, 在google里输入”ticker+ycharts”就可以马上看到下图这样的汇总,的确是灰常好用。

另外一个有意思的Chart就是下面的欧美主流媒体的bias chart,原来以为天天嘲笑Trump的CNN应该是很左的,其实在这个chart上ta竟然还算是很靠近Neutral呢。。。看起来还是要继续学习更多的媒体常识啊。。。

最后总结一下近期最大的information gethering improvements,基本是

  1. 养成了听podcast的好习惯,经常听的比如NYT的daily,还有Dan Harris (not Sam Harris)的10% Happier,当然还有NPR的一些news
  2. 重新开始使用RSS方式订阅经常访问的网站,大幅提高时间效率
  3. 用软路由提高了生产力-间接地。。。
  4. 看书看报纸。。。哈哈哈
