os.IsExist(err) vs os.IsNotExist(err)
/*
Watch out, os.IsExist(err) != !os.IsNotExist(err)
They are error checkers, so use them only when err != nil, and you want to handle
specific errors in a different way!
Their main purpose is to wrap around OS error messages for you, so you don't have to test
for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and
"file does not exist/directory does not exist"

My emacs cheat sheet

In penance for cracking stupid jokes on Twitter, here's my Emacs cheat sheet. Emacs has a steep learning curve, so I've tried to order them by importance so you could learn them in stages.

One overall rule of thumb: pay attention to the minibuffer (the line at the bottom of the editor). It will often guide you through a process, and also gives you hints about what state you're in, such as the middle of a multi-chord sequence.

The other rule of thumb: when in doubt, C-g it out.

Basics (mandatory)

You simply can't get by without having these at your fingertips.
