About the Guest

Aaron Hsu is the implementor of Co-dfns and an advocate for a terse and minimal array programming style. Hsu has a background in academic functional programming, and was primarily a Scheme programmer for ten years before learning APL. He was introduced to APL by Morten Kromberg while working on a GPU-hosted compiler, and switched to Dyalog APL for the project, which is now Co-dfns.
