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

First of all, it just seems like doing anything with Oracle is obnoxiously painful for no good reason. It's the nature of the beast I suppose. cx_oracle is a python module that allows you to connect to an Oracle Database and issue queries, inserts, updates..usual jazz.

Step 1:

sudo apt-get install build-essential unzip python-dev libaio-dev

#Doctest isn't palindrome# A brief introduction about [Test-driven development][1] using [doctest][2] @ [Mobile World Congress 2013][3] in Barcelona.

##Abstract## Talking about Web development, requirements are fickle and ever-changing. The most trivial request could be the straw that breaks the camel's back. [Test-driven development][1] ( TDD ) is the best weapon in our hands; the [doctest][2] is the simplest tool to explore its efficiency. And let's face it, palindromes fascinate everyone.

###Issue != Requirements### Everyday a developer has to face the problem to understand his/her requestors (employers, line managers, collegues). Unfortunately the request isn't usually clear and comprehensive, because sometimes the problem is not clear to those who ask us to solve it. Language barriers can make the problem worse. However, an example is more enlightening than thousand words. And what if we could write these examples in a language more related to us?
