For the second year, we will be hosting a Dojo at CERN, on the Friday immediately before the Open Source Summit in Edinburgh - that is, on October 19th.
Details of this event, including the call for papers, are available at http://cern.ch/centos
Information about how you can help are at https://wiki.centos.org/Events/Dojo/CERN2018
In particular, at this point, we need help spreading the word about the call for papers, or suggestions of individuals that we should solicit talks from. We're particularly interested in content that is relevant to research organizations like CERN - HPC, high-scale data storage, cloud computing, and so on - but really any CentOS-related topic is fair game.
