SLAM是 Simultaneous Localization And Mapping的 英文首字母组合,一般翻译为:同时定位与建图.同时定位与地图构建. 「同时定位与地图构建」这几个词,乍一听起来非常拗口,为了不在一开始就吓跑读者,我们先不对其进行专业的解释,用一个日常生活中形象的例子来进行说明. 初 步 认 识 S L A M 我们知道现在有不少家用的扫地机器人,可以代替人对室内进行自动清扫.早期的扫地机器人并不智能,它只是具有简单的避障功能,在室内随机游走,遇到障碍物就转弯,这样会导致有很…

一.背景 一般情况下,我们都是用一些封装好的网络框架去请求网络,对底层实现不甚关注,而大部分情况下也不需要特别关注处理.得益于因特网的协议,网络分层,我们可以只在应用层去处理业务就行.但是了解底层的一些实现,有益于我们对网络加载进行优化.本文就是关于根据http的连接复用机制来优化网络加载速度的原理与细节. 二.连接复用 对于一个普通的接口请求,通过charles抓包,查看网络请求Timing栏信息,我们可以看到类似如下请求时长信息: Duration 175 ms DNS 6 ms Conne…
