CoffeeBot 2.0
Keeps track of which coffee machines that are available at work. Version 2 is written in Kotlin for the fun of it.
What happened to v1?
Version 1 is based on node.js and Slack's RTM API. Because of various issues with the RTM API (timeouts, disconnects) v1 is deprecated. The source code can be found in the v1 branch or v1.0 tag.
