Zero knowledge databases

The idea

The idea is to provide a database as a service to end users in such a way that no one except the user herself can access the data, not even the hosting provider or the database administrator.

Advantages

A privacy- and/or security-conscious user will have more trust in such a setup.
The service provider cannot be coerced to release the data they were trusted with, and he cannot be held responsible for the content he is storing.

Type hints cheat sheet (Python 3)

This document is a quick cheat sheet showing how the PEP 484 type annotation notation represents various common types in Python 3.

This text now lives at https://github.com/MarcDiethelm/contributing/blob/master/README.md. I turned it into a Github repo so you can, you know, contribute to it by making pull requests.

Contributing

If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on Github, new technologies and and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.
