Artifact evaluation, theory and practice

Previously on the SIGOPS blog, we discussed the current status of artifact evaluation (AE) and how to improve it. At HotOS’23, we took another step in this direction: attendees discussed artifact evaluation in a panel led by Shriram Krishnamurthi (Brown), Margo Seltzer (UBC), and Neeraja Yadwadkar (UT Austin), and organized by Roberta De Viti (MPI-SWS),
