Prior to the summer school "Open Science in Practice", I knew only very little about the vast ways of operation of what is called open science. Apparently I thought I knew more than I truly did, and at the end of our five days I learned a lot which I will try to summarize here as much as possible. My second essay will be rather informal, as I got to be part of the community and had a piece of the atmosphere we all shared. It will have the flavor of a blog post, since this summer school inspired me to be informative and creative in various platforms and a blog post is certainly one way of accomplishing this.
