分布式系统是指一个你甚至不知道存在的计算机的故障可能导致你自己的计算机无法使用。
A distributed system is one in which the failure of a computer you didn’t even know existed can render your own computer unusable.
If you are ready to give up everything else and study the whole history and background of the market and all the principal companies whose stocks are on the board as carefully as a medical student studies anatomy—if you can do all that and in addition you have the cool nerves of a gambler, the sixth sense of a clairvoyant and the courage of a lion, you have a ghost of a chance.
The most successful businesses are those that focus on creating value for their customers.
