We don't have a presenter for January. Consequently, we do not meet next Wednesday.
Please consider presenting a C++ related talk. There are suggestions at https://fias.uni-frankfurt.de/pm/projects/cplusplus-usergroup/issues?query_id=36, but you are certainly not limited to these. Presentation of the C++ parts/issues in your current software project can be just as interesting and useful for the group.
We can also look into inviting a speaker on a specific topic. Alternatively, we can watch and discuss a recorded presentation on C++ (there are a lot of high quality talks freely available these days).
