Attention: This is DEPRECATED in favor of PowerLevel10K, I wrote an article about it:

• Change default shell on Arch Linux

Install oh-my-zsh with powerlevel9k theme on Arch Linux

This gist aims to facilitate the switching from bash to zsh as our defaut shell. We will be using oh-my-zsh with the powerful theme: Powerlevel9k. You will find all the links below. This process applies mainly for Arch Linux, but can be setup for any other distro (in theory :)). I'm also using Gnome Terminal and pacaur as package manager.

go mod 项目管理

go 1.11 有了对模块的实验性支持，大部分的子命令都知道如何处理一个模块，比如 run build install get list mod 子命令，第三方工具可能会支持的晚一些。

到 go 1.12 会删除对 GOPATH 的支持，go get 命令也会变成只能获取模块，不能像现在这样直接获取一个裸包。

可以用环境变量 GO111MODULE 开启或关闭模块支持，它有三个可选值：off、on、auto，默认值是 auto。

开启go mod机制

请选择go1.11以上版本

每个平台的信号定义或许有些不同。下面列出了POSIX中定义的信号。 Linux 使用34-64信号用作实时系统中。 命令man 7 signal提供了官方的信号介绍。
