SPRITZ_PLAYGROUND are informal meetings organized by our CTF team spritzers. We meet every week on Thursday afternoon, we discuss one or more topics from introduction to expert level!
Meetings will require no previous knowledge but of previous lessons. No resources other than a laptop and a few free programs are required - we'll make it clear when announcing the meeting.
Attendance and participation to the course will award 2 ECTS for M.Sc. students in Computer Science. More information on how credits are obtained will be given at the first meeting.
The meetings will be held in Italian.
Throughout the events we will use a scoreboard to host exercises: playground.spritze.rs
