节点一旦有 15 条连接就不再主动发起连接。如果你能接受入站连接，那么从连向你的节点那里可以收到远超此数的连接，否则你就封顶在 15。
Nodes stop trying to initiate connections once they have 15. If you can accept incoming connections, then you can get well above that from nodes connecting to you, otherwise you max out at 15.
我不知道有什么理由要 15 条连接。也许应该是 10。
I don't know if there's any reason to have 15 connections. Maybe it should be 10.
由于只能向外连接的节点现在大部分时间都在 15 条上下，你应该会稳定到一个均衡。45 意味着每 1 个接受入站的节点对应 3 个只出不进的节点。
Since nodes that can only connect out are probably at or near 15 most of the time now, you should level off to an equilibrium. 45 suggests a ratio of 3 out-only nodes to every 1 in-accepting node.
连接数不再是衡量网络规模的好指标了。应该有人定期通过 IRC 连到 chat.freenode.net 的 bitcoin 频道数一数用户数。那给出的是网络节点总数（TOR 节点除外）。
The number of connections won't be a good gauge of the size of the network any more. Someone should periodically IRC to the bitcoin channel on chat.freenode.net and count the number of users. That gives you the total count of network nodes (except TOR nodes).
区块生成又一次跑在了节奏前面。大约 5 天后的下次调整，难度又要上一个台阶。
Block generation is again running ahead of pace. We're in for another big step up in difficulty at the next adjustment in about 5 days.
