This presentation is about what I did from June to now. As a member of IBM C:LOUDERs, I could make a study group(called ZUA) and be a project manager. I also started my personal project, OCOL, which is for a newsletter publication with people that I met from this group. In this project, I usually write articles about computer security. *Colors from: https://www.ibm.com/design/language/ibm-logos/rebus/
