I recently installed and spent some weeks testing the past release, Mageia 9. Nice system. I'm currently learning R, one thing I noticed is that mandriva-derived distributions are some of the few that have RStudio packaged in the repositories. When LMDE 7 was released I installed it instead, as the package versions in Mageia 9 were quite old, but once Mageia 10 is released I intend to go back.
