It depends on the theme. If we're picking something in a space the group already knows well, like databases, I'll look at "Best Papers" from recent VLDB/ICDE/SIGMOD conferences. If we're exploring a topic most people are unfamiliar with, we'll go with something more foundational instead. For example, we're starting an arc on datacenters (servers, racks, networking, load balancing, power, cooling, failures, etc.), and most attendees don't have deep background there, so I found a book on the topic that we're going to read through[1].

There are other groups within Microsoft, but they usually follow a presentation format rather than a collaborative discussion. Off the top of my head, Phil Bernstein[1] and Hanuma Kodavalla[2] run great database seminars for invited speakers. I regularly attend and have presented in both forums; Phil's crowd is mostly researchers, while Hanuma's is mostly full of SQL engineers. Different from a small reading group, but still great.

Appreciate the paper link! We like going back to the basics sometimes, so I'll definitely take a look.
