Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

OpenWrt Docker镜像构建

为了在Docker中运行OpenWrt系统，我们需要用到OpenWrt的docker镜像,网上有很多人分享已经制作好的镜像。但是，每个人都有自己不同的需求，自己学会制作镜像就显得特别重要了。

其实使用OpenWrt的固件, 可以很方便的构建Docker镜像，这里的固件不光是官方固件，也可以是经过自己定制编译生成的固件。

直接使用

Zygisk 源码分析

以下分析基于 Magisk 76ddfeb93a8b3612cd68988323f422e996751e16

由于 Magisk 更新太快了，决定弃坑，自己去看源码罢！

Zygisk 注入到 Zygote 进程

Zygisk 加载是通过替换 app_process ，修改 LD_PRELOAD ，再执行原 app_process 实现的。
