Backing up a GPG private key to a QR code

Use at your own risk! As with any backup method, test out your backup by restoring from it before you trust it.

1. Install qrcode to generate the QR code:

    pip install qrcode
   

2. Export the key, piping the output to qr, and save this to a png file:

Golang SliceTricks, documented

This is a fork of the SliceTricks page of the golang wiki, but with documentation for each of the "tricks." I believe that documentation has been omitted because the names refer to the old container/vector, but that package no longer exists in the standard library, so you can't find it on godoc. I created this by referring to this archive.org cache, (TODO: find git commit).
