The CERN Summer Student (link is external) program is in full swing and ROOT is part of it. Today, the second instance of the ROOT Summer Students' Course takes place. A great success: already 120 students attended the course and a another instance has still to take place. Many exciting innovations were put in place in the program (link is external), including the usage of a micro CernVM virtual machine and the CERN jupyter notebooks' service, SWAN.
