Docker for Mac: Get host ssh access
Because I was having a similar issue I thought I'd put this here for posterity's sake.
To 'login' (attach to a screen session) in docker for mac you do,
screen ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty
login with 'root' no password.
set whatever sysctl setting you need to modify. I had to set max_user_watches for inotify.

daverigby / git show ignoring moved files
Last active March 3, 2016 16:32
For a given Git SHA, show only the lines in the commit which were not moved from elsewhere, i.e. are new. Useful for verifying patches which should just move code from A -> B and not change it.
