最近重新燃起学 go 语言的兴趣，起因是修改一个告警信息发送到 IM 的脚本，刚拿到脚本一脸蒙，再后来又要修改这个脚本又是头大。都怪我之前没有学习 go 的基础语法，临时抱佛脚行不得。所以这次下得决心把 go 作为2021年必修技能。
为了减少家庭矛盾 !_!，把家里台式电脑主系统切换到了 FreeBSD，跟游戏彻底88了，经过一个多月已经没有想玩游戏的念头了，更多的时间是在陪家人及怎么打发业余时间，经常996+大小周工作制也没有多少自己的时间，所以现在才知时间的宝贵，而人已到中年。
下面记录了如何在 FreeBSD 里安装 openjdk，安装 jetbrains 出口的 goland IDE编辑器。

This OpenJDK implementation requires fdescfs(5) mounted on /dev/fd and
procfs(5) mounted on /proc.
If you have not done it yet, please do the following:
mount -t fdescfs fdesc /dev/fd
mount -t procfs proc /proc
To make it permanent, you need the following lines in /etc/fstab:
fdesc /dev/fd fdescfs rw 0 0
proc /proc procfs rw 0 0
