JuliaCon 2025

Parting ways with our Julia simulation after 100 million miles
2025-07-23 , Cathedral of Learning Room 324

At JuliaCon 2019, Tucker McClure gave a talk "A New Breed of Vehicle Simulation" to show how Julia-based simulation was being used at Zipline to develop autonomous aircraft that deliver life-saving medical supplies to remote areas. After 1.5 million deliveries and 100 million miles flown across seven countries, we're deprecating the Julia simulation that carried us this far and rebuilding it in Rust. Join for a post-mortem discussion of the factors that led us to this decision.


This talk will cover how Zipline used Julia for aircraft development and flight software testing, the positives of using Julia for aircraft simulation and engineering development, the pain points of using Julia in a large organization, and how the value proposition of Julia is shifting with changes in the industry.
