Fork your own Gist

This is a bookmarklet that adds a fully functional Fork button to your own Gist.

If a Fork button is already present in the page, this bookmarklet will set focus to it instead of adding another one.

The change is temporary and the button will disappear as soon as you navigate away from that Gist (clicking the Fork button does this for you as well).

disabling engineyard asset pipeline precompilation
13:04 < mferrier> Hey guys, on the rails 3.1 stack, anyone know how I would prevent the asset pipeline precompile from running?
13:06 < emachnic> mferrier: http://docs.engineyard.com/asset-pipeline.html
13:08 < mferrier> so I read, but I still want to be able to use the asset pipeline.
13:08 < mferrier> I just don't want the precompile step during deployments.
13:10 < emachnic> mferrier: Should be able to set config.assets.precompile to false IIRC
13:15 < mferrier> ah, I'm not explaining properly. I'm precompiling locally and committing the result into the repo. So I still want to be able to rake assets:precompile locally, but just not have that task happen in the engineyard stack.
13:15 < mferrier> changing the rails asset pipeline setup will prevent the local precompilation.
13:15 < emachnic> mferrier: Ahh. Let me check real quick
13:20 < adamholt> emachnic: mferrier: if you add your assets to public/assets we skip compiling them on the server - https://github.com/engineyard/engineyard-serverside/blob/maste
