If you find that vagrant box list somehow does not contain a box you previously had, you can sometimes add the box back if you still have the sources for it in ~/.vagrant.d/boxes.
$ cd ~/.vagrant.d/boxes/precise64/0/virtualbox/
$ tar czf ~/precise64.box .
$ vagrant box add precise64 ~/precise64.box
Downloading box from URL: file:/Users/ryanuber/precise64.box

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:

Hi there!
The docker cheat sheet has moved to a Github project under https://github.com/wsargent/docker-cheat-sheet.
Please click on the link above to go to the cheat sheet.
| # Create vagrant image | |
| vagrant init ubuntu12_64 http://files.vagrantup.com/precise64.box | |
| vagrant up | |
| vagrant ssh | |

| # Clone locally | |

| cd opsworks-cookbooks |
NOTE: This is out-dated, I suggest using https://github.com/dbankier/ltss instead.
This alloy.jmk adds support for using CSS-like @import "file.tss"; statements in Alloy TSS styles.
The idea for this came when discussing adding the option of including a CSS-like reset stylesheet in Alloy to make up for platform differences in (background)color, but also some good practices.
I think one of the key issues in this discussion is that there is no such thing as the base style for an app. iOS fans would like to reset to iOS-like styles, Android fans like to reset to theirs, flat UI fanatics would like everything minimalized and Bootstrap adepts will ask for a huge library of styles.
