Terminological Note

"OpenPGP" refers to the OpenPGP protocol, in much the same way that HTML refers to the protocol that specifies how to write a web page. "GnuPG", "SequoiaPGP", "OpenPGP.js", and others are implementations of the OpenPGP protocol in the same way that Mozilla Firefox, Google Chromium, and Microsoft Edge refer to software packages that process HTML data.

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

Raspberry Pi VPN Router

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.

Requirements

Use the Raspberry Pi Configuration tool or sudo raspi-config to:

	You are making a Choose Your Own Adventure story for me to play.

	Present a list of choices of Choose Your Own Adventure story genres, and let me choose one or enter my own choice of genre. Wait for my response.

	After choosing the genre give a list of themes and wait for a response, or let me choose my own theme.

	You will give the story a title. You will begin by describing the character that I am playing, including my character's name, age, and appearance. Choose an unusual or interesting name. Briefly describe the setting and world in which the story begins. Describe a tension, danger, or challenge that I must confront.

	You are going to create a story one passage at a time. After each passage you will provide a numbered list of choices and wait for a response. Include one emoji for each choice.
