if __name__ == "__main__": main() ★多进程同步之Event（事件） 使用mul�processing.Event()方法创建一个事件对象， 事件用于进程之间的通信。一个进程发出一个信号，其他一个或者多 个进程等待，调用Event对象的wait方法，进程则会被阻塞，直到别的 进程set之后才会被唤醒。 import random import multiprocessing import time def operator_func(event, name): print(name + ": 我可以变更了吗？") event.set() # 发请求给Manager，唤醒一个挂起的线程 event.clear() event.wait() # 等待Manager的回复，释放内部所占用的琐，同时 线程被挂起，直至接收到通知被唤醒或超时 randint(1, 3)) event.set() # 再次发消息给Manager，唤醒一个挂起的线程 event.clear() event.wait() # 等待Manager的回复 event.clear() print(name + ": 收到，现在变更") def manager_func(event, name): event.wait() #

injection across critical systems ii. Simulate and rehearse accidents for practice 1. Schedule the event 2. Give teams time to prepare, make changes, and establish procedures 3. Execute iii. Expose latent INFORMATION SECURITY INTO PRODUCTION TELEMETRY i. Often production breaches are detected months after the event. A primary reason is due to no one regularly reviewing production logs ii. Use telemetry to help

environments layer a. Events, logs, & metrics b. Common service to centralize, rotate, and delete 2. Event router responsible for storing our events and metrics a. Enables visualization, trending, alerting
