The Joel Test: 12 Steps to Better Code

Have you ever heard of SEMA? It’s a fairly esoteric system for measuring how good a software team is. No, wait! Don’t follow that link! It will take you about six years just to understand that stuff.

变量声明

• var，语法：var name type=value
  • 局部变量
  • 包变量
  • 块声明

基础语法：main函数要点

• 无参数、无返回值

• main方法必须要在main包里面go run main.go就可以执行

mount -t vboxsf tools /mnt/share

报错了：/sbin/mount.vboxsf: mounting failed with the error: No such device
