A self-service coffee machine at my university library.
With a bit of napkin math, I figured out in the current grant climate, I'd have to submit at least 25 applications until the probability of me receiving at least one of those would be bigger than 90%. Which means that there's still a 10% chance of that *not* happening, even after 25 attempts.
I could proudly tell IT to nuke an entire database into orbit
Poor documentation is the #1 cause for high blood pressure.
A photo of me after the ceremony
A recording of the ritual. It consists of moving up to the lectern where the conferrer resides. They then say "Salve, sapientissime"; "Accipe coronam", "Accipe diplomam", "Vale, doctissime doctor" and guide the conferred over the lectern to the other side.
Yet another GDPR request because companies keep forcing accounts on me.

GitHub now wants to use all your data unless you opt out. Silly me, I never had a single interaction with the Codex model!

A screenshot showing the two datasets side by side. You can clearly see the end of Gorman's tenure in the left dataset with the last line in which his ID number appears, which coincides with his last year as a minority leader in the Senate. Interestingly, he already left office prematurely before that, but incidentally *not* because he died. This is an outlier.
What can I say? *shrugs*
