I'm on the agenda for the #ukoug conference 2025.
9:00 a.m. on Monday morning (I tell myself that that's to encourage people to be on-site early enough to attend the opening keynote afterwards)

We are saddened by the passing of Jim Lovell, commander of Apollo 13 and a four-time spaceflight veteran.
Lovell's life and work inspired millions. His courage under pressure helped forge our path to the Moon and beyond—a journey that continues today. go.nasa.gov/41tbrpq

I've just come across a blog note I wrote a few years ago about unexpected (and unreliable) results from v$undostat when it reports the "maxquerylen / id"; it's probably worth knowing about it:

The old mathematical ones are the best.
Maybe jokes are like mathematics. You either get them or you don't. But if you need a clue for Vishal's joke, this might help:
