Summary

TechBrunch returns with a functional programming edition, gathering developers and the mathematically curious over a relaxed brunch at the Beltempo restaurant in Iidabashi. The focus is the abstractions behind functional programming and category theory, aimed at people who enjoy the mathematical foundations of software. Expect deep dives into concepts like monoids, functors, applicatives and monads, plus discussion of how category theory applies to practical software design. Conversation also reaches into adjacent fields such as algebra, graph theory, set theory and topology. The crowd tends to include users of languages like Clojure, Haskell, OCaml and Scala, alongside anyone simply curious about the ideas. This is a deliberately small gathering rather than a large meetup. First-time attendees who RSVP and are confirmed on the attendee list get their meal for free. RSVP is encouraged, since the group may relocate and start a little earlier than the posted time.

About the community

TechBrunch is a small, recurring meetup where people with a technical bent gather over a meal to dig into focused topics, this time functional programming and category theory. The tone is relaxed and discussion-driven, welcoming both practitioners of functional languages and the merely curious, with intentionally small turnout.
