the bar was high for the ECB to surprise dovishly,

As we noted earlier, the bar was high for the ECB to surprise dovishly, yet it did just that moments ago when it announced (amid unchanged rates) that not only is it announcing a new series of TLTRO "starting in September 2019 and ending in March 2021, each with a maturity of two years", but also changed its rate guidance, extending its rate guidance beyond "at least the summer of 2019" and now sees rates on hold "at least through the end of 2019."

《思想的力量：哲学导论》



445. 社会正义的两个原则
1）要求每个人平等地拥有“能够和他人的同等自由和谐相容的最大限度的基本自由。”
2）要求人这样来安排社会和经济的不平等，“使得（a）人们能合理地指望它们对每个人都有利；（b）地位和官职对所有人开放。”
其中第一条原则优先于第二条原则。


这个概念说的是：一切的社会性的善（例如自由、收入、机遇）都应该平等分配，除非不平等的分配对每个人都有利。

446. 个人的权利
Rawls没有明确把个人的“权利”作为一个主题来讨论过。但他的理论经过解读以后，明显可以看成是对这些权利的保护。

447. 自尊
在约翰-罗尔斯看来，最重要的善就是自尊。包括两个方面：1）这是一种信念，相信自己的计划、抱负是有价值的；2）相信自己有能力实现这些目标。
没了自尊，做什么事都变得毫无意义；即使有些行动确实存在着目标，我们也会缺乏行动的意志。“一切欲望和行动都成了空虚和徒劳，围绕我们的只有无动于衷和玩世不恭。”

448. 《政治自由主义》（Political Liberalism, 1993）罗尔斯对“随着时间流逝，当代民主社会中依然存在相互不一致的宗教和哲学教条，那么他的公平的正义概念如何能够得到它们的认同呢？”这类问题作了更为仔细的考察。

Blockchain:

Consistency
As discussed in prior chapters, hashing and the Merkle root of all transactions and behaviors on the blockchain allow for an easy calculation of consistency.
If consistency is broken on a blockchain, it will be noticed instantly. Blockchains are designed to never be inconsistent. However, just because data is consistent does not mean it is accurate. These issues will be discussed in Chapter 21 , Scalability and Other Challenges.
Peer-to-peer systems
Most computer systems in use today are client–server. A good example is your web browser and typical web applications. You load up Google Chrome or another browser, go to a website, and your computer (the client) connects to the server. All communication on the system is between you and the server. Any other connections (such as chatting with a friend on Facebook) happen with your client connected to the server and the server connected to another client with the server acting as the go-between.
Peer-to-peer systems are about cutting out the server. In a peer-to-peer system, your computer and your friend's computer would connect directly, with no server in between them.
The following is a diagram that illustrates the peer-to-peer architecture:
