Adventures in Python Core Dumping

After watching Bryan Cantrill's presentation on [Running Aground: Debugging Docker in Production][aground] I got all excited (and strangely nostalgic) about the possibility of core-dumping server-side Python apps whenever they go awry. This would theoretically allow me to fully inspect the state of the program at the point it exploded, rather than relying solely on the information of a stack trace.

A quick guide to setting up keyboard shortcuts for a push-to-talk microphone.

Install xbindkeys:
```
sudo apt install xbindkeys
```
Find the required keycode for xbindkeys:
```
touch $HOME/.xbindkeysrc
```

xbindkeys --key
