Building geometry processing tools using multiple dispatch

Welcome to the October 2025 CAJUN meetup. We welcome Anshul Singhvi speaking about GeometryOps. This meetup will be at the Akamai office in Kendall Square. See directions below.

Talk Details:
Building geometry processing tools using multiple dispatch

[GeometryOps.jl](https://github.com/JuliaGeo/GeometryOps.jl) is a geospatial processing framework written in pure Julia. It uses multiple dispatch to be fast (in some cases, orders of magnitude faster than existing solutions) but as a result also runs into pitfalls like method ambiguity and type instability. In this talk we'll explore both the good parts of multiple dispatch in Julia and the parts where we need some workarounds to get it working right.

Speaker:
Anshul Singhvi is a contributor to the Julia geospatial stack as well as the Makie.jl visualization library and the Julia documentation stack. Currently working on the Dyad simulation platform at JuliaHub.

Time:
Arrival will be at 4:30. We'll plan to start the talk around 4:45 or 5pm. The talk will last 30-40 minutes.

Location:
145 Broadway. The entrance is from Broadway. There's a security desk once you enter and they will sign you in.

Important notes about arrival:

• There is ongoing construction at the building next door, so traffic on Broadway is a mess. It is advisable to walk, bike, take public transport, or park somewhere near MIT and walk.
• Please bring some government-issued ID to the event (required by Akamai security). Non-US Passports are OK.
• Please RSVP by October 13 so that we can get all the names over to security. If you happen to RSVP after that date, please message Philip Tellis on the julia slack or in the #boston-local channel.
