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

Find the dependent child images on Docker

When you try to remove the docker image with the following command

docker rmi 6795374be8c1

Sometimes you might be facing below error:

Error response from daemon: conflict: unable to delete 6795374be8c1 (cannot be forced) - image has dependent child images

Below is the Docker command line used to find the dependent child images

Setting up Vim as your Go IDE

Intro

I've been wanting to do a serious project in Go. One thing holding me back has been a my working environment. As a huge PyCharm user, I was hoping the Go IDE plugin for IntelliJ IDEA would fit my needs. However, it never felt quite right. After a previous experiment a few years ago using Vim, I knew how powerful it could be if I put in the time to make it so. Luckily there are plugins for almost anything you need to do with Go or what you would expect form and IDE. While this is no where near comprehensive, it will get you writing code, building and testing with the power you would expect from Vim.

Getting Started

I'm assuming you're coming with a clean slate. For me this was OSX so I used MacVim. There is nothing in my config files that assumes this is the case.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

	This gist includes components of a oozie (trigger file initiated) coordinator job -
	scripts/code, sample data and commands; Oozie actions covered: hdfs action, email action,
	java main action, hive action; Oozie controls covered: decision, fork-join; The workflow
	includes a sub-workflow that runs two hive actions concurrently. The hive table is
	partitioned; Parsing uses hive-regex serde, and Java-regex. Also, the java mapper, gets
	the input directory path and includes part of it in the key.

	Usecase
	-------
	Parse Syslog generated log files to generate reports;
