/**
 * Arbitrary-length tuples
 * =======================
 * 
 * Working with tuples of unknown length in TypeScript is a pain. Most library authors fall back on enumerating all possible
 * tuple lengths up to a threshold (see an example here https://github.com/pelotom/runtypes/blob/fe19290d375c8818d2c52243ddc2911c8369db37/src/types/tuple.ts )
 * 
 * In this gist, I'm attempting to leverage recursion to provide support for arbitrary length tuples. This has the potential
 * to make some kinds of declarative APIs nicer and enhance type inference in some cases.
 * This example shows how to take a variable-length tuple as an input, transform each of its types and use the resulting

shadowsocks作者说的很对的一句话与感想

个人感想:

• 中国人很投机, 包括本人在部分情况下也是投机者. 总想不劳而获, 抄袭他人劳动成果. 想想我们学生时代的抄袭作弊之风盛行便可知... (然而为什么会这样)
• "土皇帝"情节, 因自己在某方面上比别人强, 听听粉丝的追捧, 就觉得自己不可一世, 比别人优越, 殊不知人外有人山外有山, 而且自己在其他方面也有不如他人的地方. (然而为什么会这样)
• 家长情节 总想要一个"家长"来管理一切, 把应该由自己解决的问题抛给别人"包办解决", 图一时之便. 久而久之结果就是并不了解你一切的"家长""包办解决"你的一切, 而你却失去了基本的思考解决问题能力, 看不到目标, 找不到方法, 只好任由"家长"摆布. 这种"爱"是现实的囚笼. (然而为什么会这样)

Confusing Scala serialization puzzle

This writeup describes a tricky Scala serialization issue that we ran into while porting Spark to Scala 2.11.

First, let's create a factory that builds anonymous functions:

class FunctionFactory extends Serializable {
  // This method returns a function whose $outer scope is this class.
  // Note that the function does not reference any variables in this scope,

SSL 设计目标:

1. 防内容篡改
2. 防冒充服务器身份
3. 加密通信内容

而翻墙的目标:

1. 不被检测出客户端在访问什么网站
2. 不被检测出服务器在提供翻墙服务

捕捉浏览器中的JS运行时错误，主要通过监听window.onerror来实现。但是对于不同的脚本执行方式以及不同的浏览器，能捕获到的信息会有区别。

window.onerror 讲接收3个参数：

• msg：错误描述，比如：a is not defined
• url：出错脚本所在的url
• lineNumber：出错脚本的行数

本文将对不同浏览器和不同的脚本执行方式进行测试，并总结这些区别。

/*
 * This is just an experiment. Don't read too much into the fact that these are global variables.
 * The basic idea is to combine the two steps of defining a constructor and modifying a prototype

有一存有整数的数组 A[n] (n <= 2^31 - 1, 但需要的话可以再扩大), 其中 0 <= i, A[i] <= n-1 且 i!=j 时 A[i]!=A[j] (即一个排列). 用你认为*最高效*的方法求 B=A^(-1) (即对范围内满足 A[B[i]]=i 的 B)
