一、穷人缺乏有效的避险工具
1. 穷人会生一堆孩子,但生孩子不是观念落后,而是一种理性思考,因为穷人所在的国家往往没有社会保障体系,想规避养老和医疗风险,只能依靠自己的子女,但是子女身上不确定性太多,或者早夭,或者关系不好,或者没能力养老,穷人往往采取多生几个的策略,尽量规避风险。
2. 婚姻也是一种规避风险的方式。印度的穷人一般会将自己的女儿嫁到不远不近的村庄,如果两个村子太近,气候完全一样,你这里发洪水,我这个也发洪水,谁也帮不上谁。两个村子隔开一段距离,气候条件就不一样了,遇到灾险,不至于全军覆没,还可互相帮助。

动态规划:从新手到专家
主要是参考这篇博文:http://www.hawstein.com/posts/dp-novice-to-advanced.html(动态规划:从新手到专家)
看完入门,有点感觉了,然后是LIS问题,文中又提到了LCS问题,说这个更基础,于是转去看LCS。
关于LCS,有一篇清晰易懂的好博,见:http://songlee24.github.io/2014/11/27/dynamic-programming/(神奕的博客)

How Sharding Works
This is a continuation of my last post, why I love databases
Your application suddenly becomes popular. Traffic and data is starting to grow, and your database gets more overloaded every day. People on the internet tell you to scale your database by sharding, but you don’t reall ...
少年若天性,习惯如自然。意思是讲一个人,小时候接受教育和影响所形成的习惯,就像先天形成和与生俱来一样稳固,终生都会起作用。近代英国教育家洛克在其《教育漫话》中说道:你便应该利用一切时机,给孩子们一种不可缺少的练习,使它们养成一种良好的习惯,而习惯一旦养成以后,便不用借助记忆,很容易地、很自然地发生作用了。
我们总在说忙忙忙,但是孩子的教育根本不可能等着我们来弥补,只要稍微有点忽略,孩子的成长变化会很明显。有些毛病一旦养成,会花费很多精力来改正,甚至根本无法纠正。 所以不管挣了多少钱,事业发展有多顺利,如果孩子的教育不得当,将来老了会后悔。
教育是一项漫长的工程,需要父母陪伴孩子共同成长,给 ...

Why are we doing this?

WASHINGTON— When you think of a workspace, the cubicles in a traditional office are probably the first thing that comes to mind. Following Uber and Airbnb, the sharing economy has brought a new kind of work environment to the United States and the world in recent years.
