不管站哪边，给着急的人让让路总是好的。

@plko345 其实道理很简单。RH 系的流行就是因为很多 java 系的软件只提供 rpm 包。

同样的道理，机器学习很多软件优先提供 deb 包。

什么稳定不稳定都是骗人的。

其实 python 这里就等于：

var v=[];
function f (a = v, b = 1) { a.push(b); return a;}


解释器一次性扫了默认参数之后不会再次清空。

@glasslion 估计有个逻辑是去 cassandra 里取用户名和 id。然后那个默认参数的 ids 就会越来越长，直到把 cassandra 也查挂。而且这个逻辑上是没问题的。传入 ids 长，得到的返回是个 dict，你还是能获取到正确的值。只不过会附加很多没用的 key。

> This took so long to catch because we returned the values as a dictionary, and the dictionary always included the necessary values, it just happened to also include tens of thousands of extraneous values too

@glasslion 原文大概意思是 MyNews 页面卡，初步原因估计 cassandra 太卡。就重写了缓存层。

> this time with the goal of rewriting our MyNews implementation from scratch. The current version wrote into Cassandra, and its load was crushing the clusters, breaking the social functionality, and degrading all other functionality around it. We decided to rewrite to store the data in Redis
