# Get the value of a tag for a running EC2 instance.

How to share a folder with a docker container on OSX

Mounting shared folders between OSX and the docker container is tricky due to the intermediate boot2docker VM. You can't use the usual docker -v option as the docker server knows nothing about the OSX filesystem - it can only mount folders from the boot2docker filesystem. Fortunately, you can work around this using SSHFS.

# This script can be used as a Alfred Script Filter in a custom workflow for converting numbers to durations. 
# To do so, create a new workflow, add a script filter with contents './convert "$@"', ensuring that the 
# query is passed as "with input as argv".
#
# It's useful to connect a "Copy to Clipboard" output action to make it easier to paste the duration string somewhere.
