Summary

TechBrunch returns with a Functional Programming Edition, gathering developers and mathematicians at the Beltempo restaurant inside Hotel Metropolitan Edmont Tokyo. The session unpacks the abstractions behind functional programming and category theory, with relaxed discussion over brunch rather than slides. Expected ground covers monoids, functors, applicatives, and monads, plus how category theory shows up in practical software design and adjacent fields like algebra, graph theory, set theory, and topology. The crowd is aimed at Clojure, Haskell, OCaml, and Scala enthusiasts, working mathematicians, and developers curious about functional paradigms. This is a small group format, so RSVPs matter for finding the group on the day. First-time attendees who RSVP and appear on the confirmed list get their meal covered.

About the community

TechBrunch is a small, recurring gathering for developers, mathematicians, and computer scientists who enjoy discussing the mathematical foundations of software over a relaxed hotel brunch. Sessions favor conversation over presentations, with topics rotating through functional languages, category theory, and adjacent mathematics.
