同意, 我经常用这个题目, 实际情况是 10 个有 9 个只能到双重循环, 剩下一个能进一步到使用集合之类的数据结构.

大多数人对算法复杂度都没有概念, 经常提出一些奇奇怪怪的优化方案, 比如使用 Steam 流, 用 ForEach, 两个列表先排序等等, 当然这里是小公司, 对于大厂人员, 素质想来会高一点吧

@Scarb 好像有点理解了, 所有的消息会广播给所有的消费组, 但是组内会直接拉取全部并过滤, 所以如果我想要的是一部分消费 t1, 一部分消费 t2, 搞两个消费组就行, 我之前以为消息只回传一次, 一边消费完了就没有了, 其实如果新建消费组订阅的话, 消费位点会从 0 开始, 这样理解对吧

@onepunch 我就是按文档写的呀, 按我的理解, 我生产了一条 tag=t1 的消息, 然后我订阅 tag=t2 的消息, 这个消息不应该被消费者收到, 我也确实没有收到, 但是这条消息同时也应该留在队列里面, 不应该是被消费的状态, 但是我这里确实显示被消费了, 所以百思不得其解

这里提到一个商业库 ExtenXLS 好像可以, 考虑吗?

经过几天研究, 可能搞定了, 主要还是靠 pmset -g log 分析日志, 看 WakeRequest 都是些什么东西

一开始是 CSPNEvaluation, 反正是跟 PowerNap 有关的, 想办法改配置文件禁用掉了, 不行

后来是一些 Scheduled power events, 用 sudo pmset schedule cancelall 全部取消掉, 还是不行

再后来发现第二天所有的计划任务又重新冒出来了, google 之后, 先全部 cancel 掉, 然后 sudo chflags schg /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist 把配置文件设为只读, 貌似可以了

现在过去 2 天都没有半夜耗电的毛病了, 感觉差不多应该是好了, 真是艰难啊

昨天晚上观察了一下, 问题依旧, 早上起来只剩 50%电, 观察活动监视器的能耗没有结论, 因为这个就像是普通的唤醒电脑的样子, 都是一些正常的 APP 的待机能耗使用, 整个看上去就像是半夜 2 点电脑被唤醒打开, 然后 APP 正常待机工作的感觉, 但是实际上是全程不插电, 没有任何外接, 合盖的情况下发生的, 完全搞不懂了, 看日志的话, 只能看到是 0 点的时候进入睡眠, 但是只计划睡眠 2 个小时, 然后两个小时后 DarkWake from Deep Idle, 时间是 6 小时, 反正搞不懂这些计划安排是怎么来的, 头大
