which its policies are expressed as code.” c. CREATE A SINGLE, SHARED SOURCE CODE REPOSITORY FOR OUR ENTIRE ORGANIZATION i. Firm-wide shared source code repository is powerful way to share local discoveries discoveries to the entire organization 1. Configuration standards for libraries, infrastructure, and environments 2. Deployment tools 3. Testing standards and tools, including security 4. Deployment pipeline DOCUMENTATION AND COMMUNITIES OF PRACTICE i. Ensure automated tests demonstrate use and behavior of libraries and components ii. Test suite becomes the living documentation of the system specification and

sharing information to better enable the organization to achieve its mission. Responsibilities are shared throughout the value stream, and failure results in reflection and genuine inquiry. iv. INSTITUTIONALIZE forming of new institutional learning 2. Enables experimentation with less impact d. AGREE ON A SHARED GOAL i. Define a measurable goal with a clearly defined deadline approximately 6 months to 2 years reinforce desired behavior - anthropologists describe tools as a cultural artifact iii. Create shared backlogs and reporting 9. Ch. 7 How to design Our Organization and Architecture with Conway’s Law

dict()来创建 共享变量 import multiprocessing import os import time import random def work_func(lock, shared_var): for i in range(10): lock.acquire() print("进程 {} 已获取 锁".format(multiprocessing shared_var.value += n time.sleep(random.randint(0, 1)) shared_var.value -= n print("进程 {} 里面查看shared_var.value为： {}".format(multiprocessing.current_process().name, shared_var current_process().name)) def main(): process_list = [] lock = multiprocessing.Lock() shared_var = multiprocessing.Value('i', 0) # 第一个参数 i表示整数，还可为d（浮点数），第2个参数表示初始值 print("本机cpu为", os.cpu_count()

SINGLE REPOSITORY OF TRUTH FOR THE ENTIRE SYSTEM i. ALL parts (code & environments) of the system are shared in a version control repository ii. Version control is for everyone in the value stream iii. Everything monitoring, logging, and other tools in pre-production environments as in production v. Dev & Ops gain shared mastery of application & environment interactions 3. Ch. 10 Enable Fast and Reliable Automated Testing

of Feedback 1. Introduction a. Goal – Implement fast feedback loops i. Enable working towards shared goals ii. See problems as they occur iii. Enable quick detection & recovery iv. Ensure features
