# [2019.09.19] Free Workshops As the registration was closing at the day when I decided to buy a ticket for the conference, I managed to register only for a tutorial, but not for workshops. Today I wondered whether anybody would check my eligibility to visit a workshop on online recommender systems in the second half of the day. Nobody even tried to do that:) I liked both the tutorial on recommendations in a marketplace and the talk about building a recommender based on Elasticsearch. My free time today was mostly dedicated to hunting for some wine and cheese to bring back to Russia. Today also was the last day when I used a bicycle. In total, I spent about seven hours riding and covered more than 60 km during these days.
