When you import movies into iMovie 10 libraries, the file is always copied, wasting space and hindering editability. This script replaces the copy with a hardlink, reclaiming disk space.
View dedup-imovie-library
#!/usr/bin/env ruby
# Usage: dedup-imovie-library LIBRARY ORIGINALS
# Goes through an iMovie 10 library and replaces all the "Original Media" with
# symlinks to the actual original media, in order to conserve disk space. Note
# that because they're symlinks, if the path to the originals changes (e.g. you
# rename the external drive they are on) then the links will be broken.
# This assumes you've already imported the files into iMovie and waited for them

Precompile assets locally but keep the manifest files in source control

This setup will allow you to precompile assets locally and keep them separated depending on the environment. To precompile assets locally run RAILS_ENV=production COMPILE_ASSETS=1 rake assets:precompile. Using an ENV var like this removes the need for having therubyracer or some other javascript engine on your server instances since they aren't actually running the precompilation task.
