I was long overdue to attend a conference in person: the last conference I attended was POPL 2020. This year’s PLDI was in Orlando, Florida at the height of a hot, humid summer in the largest conference center I have ever seen (we did a lot of walking within the conference center). PLDI was co-located with other conferences including the hardware conference ISCA as part of the Federated Computing Research Conference (FCRC) and I dropped in on a few of the ISCA talks.
