    How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6
Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

(C-x means ctrl+x, M-x means alt+x)
Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:
remap prefix to Control + a
