什么是持久化缓存? 原文链接https://sebastianblade.com/using-webpack-to-achieve-long-term-cache/ 缓存(cache)一直是前端性能优化的重头戏,利用好静态资源的缓存机制,可以使我们的 web 应用更加快速和稳定.仅仅简单的资源缓存是不够的,我们还要为不断更新的资源做持久化缓存(Long term cache).以前我们能利用服务端模板和构建打包,来给资源增加版本标记,如 app.js?v=1.0.0,但在大流量的网站中,这种更新…

VS2015编译boost1.62 Boost库是一个可移植.提供源代码的C++库,作为标准库的后备,是C++标准化进程的开发引擎之一. Boost库由C++标准委员会库工作组成员发起,其中有些内容有望成为下一代C++标准库内容.在C++社区中影响甚大,是不折不扣的"准"标准库.Boost由于其对跨平台的强调,对标准C++的强调,与编写平台无关.大部分boost库功能的使用只需包括相应头文件即可,少数(如正则表达式库,文件系统库等)需要链接库.但Boost中也有很多是实验性质的东西,在…

通过Gradle我们可以很方便的使用内置jetty启动我们的web程序,在本地进行调试.但是在使用的过程中,我发现了几个问题,导致本地调试的效率大受影响. 如果使用gradle jettyRun启动jetty服务器后,项目里的静态资源(jsp,html,JavaScript文件)都被锁定了,导致无法实时修改这些静态资源. 既然无法实时修改这些静态资源,那意味着我们做一个很小的改动都需要先停止jetty server,然后修改,再重新启动jetty server,这样来回浪费很多时间,尤其是涉及前…
