Welcome to CSC 2019 Live!

"CSC 2019 Live!" (this page) is the live blog/information-sharing channel of the organisers (Sebastian, Joelma, Nikos, Jarek) and the lecturers with students during the School.

This is the place where we will post official information (schedule updates, links to surveys, logistics details of various activities) but also the fun stuff (pictures from social activities, sport competition results etc.). So please visit this page often.

I hope that you are as excited as we are to come to the warm and mostly sunny Cluj Napoca in just a couple of days! :-)

Have a safe travel - Sebastian, Joelma, Nikos and Jarek
