Salting这种技术可以用于生成随机数,并将该随机数用于计算密码的哈希。
Salting is a technique in which a random number is generated in order to compute the hash for the password.
为此,一种简单的方法就是仅在派生某个线程时才生成一个随机数,并将该随机数追加到所有输出行上。
A simple approach to this is to just generate a random number when a thread is spawned and prepend that number to all output lines.
大多数你所玩过的游戏都有某种,随机数或者伪随机数,这就意味着每个事件都存在不可预测性。
Almost any game you play has some kind of randomness or pseudorandomness which means that things change overtime somewhat unpredictably.

大多数你所玩过的游戏都有某种,随机数或者伪随机数,这就意味着每个事件都存在不可预测性。
Well, recall that very basic building block we introduced 1 last week which allowed you to grab a random number between 1 and 10 or 1 or a hundred.
好吧,让我们先回想一下上周介绍过的,能产生1~10之间,或者1~100之间随机数的1,基本构建块。
And so you have to figure out how to take that randomness out of the experiment.
因此你要明白怎么把随机数从试验中拿出来,有些时候你没法做一次有效的实验。
