A alternative-NEP on masking and missing values

The principle of this aNEP is to separate the APIs for masking and for missing values, according to

• The current implementation of masked arrays
• Nathaniel Smith's proposal.

# Several of the ColorBrewer maps are "qualitative", meaning
# they are just a group of colors that can be used together 
# for categories of data.  So I remapped Accent to segments 
# instead of continuous:

# Actually, these should be used with ListedColormap, and 
# the number of colors should depend on the number of 
# categories in the data, with colors removed from the 
# list in a certain order?

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:
