// 其实这题可以写的很简单，它的关键根本不是CAS操作。

// 使用一个标志（flag也好，status判断也罢）来避免Start和Dispose重入是很容易
// 想到的手段，很多同学也这么做了。大部分同学遇到的问题是：假如StartCore已经
// 启动，那么如何让Dispose方法等待其完成。有些同学用while (true)，有些同学用
// 锁，但都避免不了让Dispose线程等待Start线程。

// 这里“避免等待”的关键在于要跳出思维界限：谁说DisposeCore方法一定要在Dispose
// 方法里执行的？我们就不能在Start里销毁对象吗？

// Promise.all is good for executing many promises at once
Promise.all([
  promise1,
  promise2
]);

// Promise.resolve is good for wrapping synchronous code
Promise.resolve().then(function () {
  if (somethingIsNotRight()) {
    throw new Error("I will be rejected asynchronously!");

mysqldump to JSON

Python script to convert mysqldump output to JSON file. Most of the code was borrowed from github.com/jamesmishra/mysqldump-to-csv

You'll want to update the 'parse_row' function to map each item in a row to a dictionary.

Running the script

// sending to sender-client only
socket.emit('message', "this is a test");

// sending to all clients, include sender
io.emit('message', "this is a test");

// sending to all clients except sender
socket.broadcast.emit('message', "this is a test");

// sending to all clients in 'game' room(channel) except sender
