# [2018.10.14] Quiet Day

I felt much better today and tried not only to do some household
chores but also to prepare another version of a talk I will give in 
the beginning of the next year in Kiev. The talk is based on my
experience of evaluation recommender systems working in production
environment and how it differs from evaluation of the same ML models
when you're doing research.

I decided not to sit a final test of my massage learning course 
because I still have no idea about how the theory given to us was 
related to practical skills I acquired. My skills were only assessed
by several other students and my wife but nobody told me that my 
massage was bad or inefficient yet. And I know one good way to 
develop it, namely having some practice in the near future:)
