Easy responsive sprites with background-size using grunt-spritesmith and SCSS

Requires grunt-spritesmith which generates a spritesheet from a bunch of images.

This gist passes a custom template for spritesmith to generate the SCSS file.

Gruntfile.js

sprite: {
 src: "images/*.png",

# If you don't do this you will have to add the host IP in INTERNAL_IPS = ('127.0.0.1',)

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
