How to write a friendly reminder bot

In this presentation given at the EuroPython 2015 in Bilbao, I show how the hangups library can be used in order to write a small chatbot that connects to Google Hangouts and reminds you or someone else to take his/her medication. The secure and recommended OAuth2 protocol is used to authorize the bot application in the Google Developers Console in order to access the Google+ Hangouts API. Subsequently, I explain how to use an event-driven library to write a bot that sends scheduled messages, waits for a proper reply and repeats the question if need be. Thereby, a primer on event-driven, asynchronous architectures is given.

The source code can be downloaded on GitHub and the slides are available as html preview.
