Printer-friendly support threads on Simple bank

Here's a messy yet working way to print support threads from Simple Bank. I don't make the printed thread look the same, I only put the messages and ONLY the messages in chronological order.

The method below may no longer work when the Simple site updates. Please ping me here or on Reddit (u/vzen) if this page needs updating.

Quick and easy, and bad-habit forming

BEWARE!! In 100% of circumstances it is a huge, nasty, no-good, blood-red flag for a stranger on the internet like me to ask you to run arbitrary code with your bank portal visible. But because not everyone reading this page is an engineer, I have to make this easy somehow. Just do NOT trust me off the bat. You really should read on to see how I break this code down and show you what each instruction does in plain English.

But for convenience of less-technically inclined users, you can do one of two things:

List Git author name with highest number of commits for paths matching given glob. Used to deduce good first contacts when researching parts of big projects
#!/usr/bin/env python
import os, subprocess, sys, glob
Big teams with little documentation use oral history to share knowledge.
This script tells you the authors with the most Git commits for each path
matching a given glob, so that you might have a good first contact when
learning about a part of a project from a bird's eye view.
I find this useful in my jobs, but there are caveats:
