Why did the writer complain to the people behind him?
Last week I went to the theatre. I had a very good seat. The play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. ‘I can’t hear a word!’ I said angrily. ‘It’s none of your business,’ the young man said rudely. ‘This is a private conversation!’
Layered Process Confirmations (LPC) is a quality management tool used primarily in manufacturing and production environments. It involves multiple layers of verification throughout the production process to ensure that every step meets specified quality standards. Here are some key aspects of LPC:

The phrase “Stay Hungry. Stay Foolish.” has an intriguing and deep history, which ties together personal inspiration, cultural movements, and a vision of the future.
It originated from the final issue of The Whole Earth Catalog, published in 1974. This catalog, created by Stewart Brand and his team, was a collection of tools, resources, and advice for people interested in sustainability, personal growth, and alternative lifestyles. The catalog’s mission was to offer practical advice for a new generation of thinkers, creatives, and adventurers.
The cover of the last issue featured a photograph of a rural road at dawn, symbolizing a path of possibility and new beginnings. Beneath the image, the words “Stay Hungry. Stay Foolish.” were printed, serving as a farewell message from the catalog’s team. These words weren’t just a sign-off; they encapsulated the spirit of curiosity, the willingness to take risks, and the idea of always seeking more, never settling for comfort.
Steve Jobs, when he gave his famous commencement speech at Stanford University in 2005, referred to this quote from The Whole Earth Catalog. He explained how it inspired him during his youth, linking it to his own experiences of exploration, adventure, and innovation. The quote perfectly reflected Jobs’s own approach to life: a relentless hunger for knowledge and a willingness to make foolish mistakes in the pursuit of greatness.
Jobs admired Stewart Brand’s work so much that he later sought out Brand’s autograph, revealing how deeply this phrase resonated with him. Jobs said in his speech, “Stay Hungry. Stay Foolish” was something he wished for himself, and it was his message to the graduating class as they embarked on their own journeys.
Basic word
Make requirements less dumb
不要提太蠢的需求。尤其聪明人给的需求更是危险,因为你可能不会去质疑他;
Delete parts or process
删除需求当中所有你能删除的部分和流程,后来可能也会加回来,但不超过10%,如果后来加回来的部分不到10% 证明删得还不够;
Simplify or Optimize
简化和优化,Elon特別强调优化要放在第三步。很多聪明的工程师最常犯的错误,就是老是在优化根本不该存在的东西;
Accelerate cycle times
加速迭代,但前三点沒有做完之前先別加速,否则只是加快了自掘坟墓的速度。注意加速的是迭代,而不是速度。迭代是一个循环,通过这个循环我们可以不停的验证当前推进的方向,并且持续的进行改进和优化;
Automate
最后才是自动化。按照Elon自己说法,他一直都希望Tesla 工厂中能够有更多的工人而不是全部都由机器人来工作。自动化的弊端有三个,分别是1)高昂的成本;2)极高的出错几率;3)妨碍引入新特性。。而 Elon真正希望构建的是一个可以随时更换组件、流程、探索新特性的并行系统;
Elon Musk 说他个人犯了上述五个步骤”反过来”做的错误很多次,他先做自动化,再进行加速优化,最后才想到要刪掉沒必要存在的东西
