Residence time (Ecology 🏞️)
The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume. The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution, or in terms of its average, known as mean reside...

So I am attempting to understand Queueing Theory that is more advanced than Little's Law and of course came across Defunctland's history of Disney's FastPass. I had a big guffaw when they showed an excerpt of a M/M/1 paper, scoffed at how you'd have to hire an engineering team "just to get to the bottom of this incredibly niche curiosity..." and then they do just that. So great.
I troubleshot a tricky-to-observe scaling issue in a SaaS stack and built a computational queueing model to demonstrate its effects (~1400w)
