AWS Lambda初触

	2017年3月16日 by Ron

	我是来自AWS 广东社区微信2群的Ron.第一次去参加AWS分享会的时候,第一个上来的就是关于Lambda的.但当时我听完后.
	觉得这东西耦合度太高,不好.就一直没在去深入了解.那一次技术分享会,还有卓动--张穗文先生分享的Kinesis + RedShift做
	用户日志分析,和有米科技的实时日志分析,那个时候真的感叹跟AWS相见恨晚.他们两分享的东西都非常棒,直接驱使我来后自己
	去尝试开发Kinesis,SQS等.总体来说,AWS组件很多.但我毕竟刚接触没多久,所以很多AWS的组件和相关概念都还很陌生,
	或者说根本就不知道是什么东西.以下在阐释的时候,如有偏差或者错误,欢迎拍砖(我Email: [email protected])

	在这过去的半年多时间里.所有广州社区的分享会,我都去了.最近一次正好听到胖虎的Lambda的分享会.
	回来的路上我已经满脑子的开始想我最近的在做的一个东西,是否能用Lambda来实现.

一行 Python 实现树

使用 Python 内置的 defaultdict，我们可以很容易的定义一个树形数据结构：

def tree(): return defaultdict(tree)

就是这样！

youqingkui / gevent-multil-process.py

Created September 8, 2016 03:04

	#encoding=utf-8
	'''
	演示如何多进程的使用gevent,
	1、gevent和multiprocessing组合使用会有很多问题，
	所以多进程直接用subprocess.Popen,进程间不通过fork共享
	任何数据,完全独立运行,并通过socket通信
	2、进程间同步不能用multiprocessing.Event,
	因为wait()的时候会阻塞住线程，其它协程的代码无法执行，也
	不能使用gevent.event.Event()，因为它通过multiprocessing.Process
	共享到子进程后，在父进程set()，子进程wait()是不会收到信号的

Python:任务调度，定时执行

	#coding=utf-8
	import time
	import sched
	import os
	import threading
	"""
	sched模块，准确的说，它是一个调度（延时处理机制），每次想要定时执行某任务都必须写入一个调度。
	使用步骤如下：
	(1)生成调度器：
	s = sched.scheduler(time.time,time.sleep)
