Migration of this website from Drupal 7 to Drupal 9

I use this website as an archive of my scientific publications and as a place to post occasional observations on life, the world, and whatever comes my way. It's all very indulgent at this point.

Drupal + RackspaceCloud + Ubuntu + ISPConfig + Nginx (DRUIN) vs. Shared Hosting
