How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

Internal Communication DRAFT

Use asynchronous communication when possible (issues and email instead of chat), issues are preferred over email, email is preferred over chat, announcements happen via email or team standup, and people should be able to do their work without getting interrupted by chat.
- More importantly, a verbal or chat record does not spread communication widely and can vary based the person delivering the message (bias) or other tribal interpretation. A written record is always critical when it comes to questions, strategy and decisions. When decisions or information is ad-hoc is reinforces the idea that people are treated unequally, do not have a voice and are kept in the dark.
It is very OK to ask as many questions as you have, but ask them so many people can answer them and many people see the answer (so use issues or public chat channels instead of private messages or one-on-one emails) and make sure you try to document the answers.
If applicable, use github to track

This is a small demo of how to create a library in Rust and call it from Python (both CPython and PyPy) using the CFFI instead of ctypes.

CFFI is nice because:

The use of __main__.py to create executables

    |_ __main__.py
    |_ __init__.py

Being __main__.py:
