#分布式
之前说DDIA缺少很多技术原理的讲解，我春节期间看分布式事务这部分，DDIA第七章也是点了一下Serializable Snapshot Isolation（简称SSI），但是同样的也是没有给出技术原理的讲解。
就像一个清晰度不够高的图片，初看是感觉什么都有了，想放大了看细节，对不起没有。
初看觉得DDIA是神书，现在也慢慢祛魅了。
（附图是DDIA书中对Paxos等共识算法的一笔带过。一本讲分布式的书，如果不讲共识算法，那有40%以上的东西没讲到）

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
