Summary
TechBrunch returns with a functional programming edition, a small-group gathering built around the mathematical foundations of software. The conversation centers on functional programming and category theory: monoids, functors, applicatives and monads, and how those abstractions actually show up in software design. Connections to algebra, graph theory, set theory and topology are fair game.
The format is a relaxed brunch at the hotel restaurant Beltempo inside Hotel Metropolitan Edmont in Iidabashi. It suits people working in Clojure, Haskell, OCaml or Scala, mathematicians who use category theory in their work, and developers who are simply curious about the paradigm. No prior background is demanded, but the discussion goes deep.
RSVP matters here: the group may relocate, so unregistered walk-ins are not guaranteed to find it, and first-time attendees confirmed on the attendee list have their meal covered. The organizers note they may start earlier than the posted time but will be present at the scheduled hour. This is deliberately a small gathering, not a large event.
About the community
TechBrunch is a recurring meetup that pairs a technical topic with a shared meal, keeping groups deliberately small so everyone can join one conversation. Each edition picks a theme and goes deep rather than broad, and this one is aimed at the functional programming and category theory crowd. Sessions run in English over brunch at a hotel restaurant, and first-time attendees who RSVP eat for free.
