RacketCon 2026 is scheduled for Saturday, with doors opening at 8:30 a.m. PDT and talks beginning at 9 a.m. The program covers Racket and related language research, and the organizers say remote streaming and live chat will be available; recordings are expected on YouTube after the event.
RacketCon 2026 is scheduled for Saturday, with doors opening at 8:30 a.m. PDT and the first presentation starting at 9 a.m. The conference dedicated to the Racket programming language has also listed a full day of talks and says it will offer a livestream and live chat for people unable to attend in person.
The published schedule begins with Pat Hanrahan’s talk, “On Notation,” at 9 a.m. Hanrahan is identified by the organizers as a Stanford University professor emeritus who led the design of RenderMan at Pixar, co-founded Tableau and received the 2019 ACM Turing Award. A break is scheduled for 10 a.m., followed by talks at 10:30 a.m. and 11:10 a.m.
At 10:30 a.m., Indiana University PhD candidate Fred Fu is set to discuss type inference for untyped languages. The conference description says his work addresses challenges that arise when Typed Racket programs use macros that expand into complex code, including generated lambda expressions whose parameters programmers cannot annotate. Fu’s ongoing prototype combines occurrence typing and algebraic subtyping, according to the program.
At 11:10 a.m., Northwestern University PhD student Lucas Myers is scheduled to present Pille, a Rhombus-based language with an LLVM-based compiler. The talk description says the project aims to apply language-oriented programming to low-level and high-performance domains while retaining Rhombus-based macros. Lunch is listed for 11:50 a.m. and will be provided, according to the organizers.
A Full Day of Language Research
The schedule gives Racket users and programming-language researchers a chance to hear about work that connects the language’s extensibility with practical software challenges. The listed subjects include type inference for macro-generated code, low-level systems programming, IDE support for incomplete programs, numerical accuracy and effect handlers.
For attendees, the program spans research prototypes and tools with potential applications beyond Racket. The descriptions frame Pille as an effort to reach constrained and performance-sensitive settings, while Herbie focuses on improving the accuracy of floating-point expressions. These are the projects’ stated aims; the conference listing does not report independent evaluations or results from the talks.
The remote option also broadens access for people who cannot be at the venue. The organizers say the livestream will include live chat and that remote viewers may buy a ticket to support streaming. They have not provided a stream link or detailed participation instructions in the supplied schedule.

Saturday Program and Remote Access
RacketCon describes itself as a public gathering intended to build an inclusive community around the Racket programming language and engage both its existing community and the wider programming world. The conference website asks people to register for RacketCon 2026 and mentions discounted early registration before September 13. The supplied material does not give the year or clarify whether that discount deadline has passed.
The afternoon program is scheduled to resume at 1:30 p.m. with Mike Delmonaco’s “Treason: Making Macros and IDE Services Work Together.” Its description says Treason is a prototype designed to continue expanding macros and gathering information for IDE services even when a program is broken or incomplete. At 2:10 p.m., University of Utah associate professor and Herbie developer Pavel Panchekha is listed to speak about floating-point accuracy and the Herbie compiler. A break follows at 2:50 p.m.; at 3:30 p.m., JJ is scheduled to discuss effect handlers and the cio library for Racket and Guile Scheme.
The organizers say recordings will be posted on YouTube some time after the conference and point readers to presentations from previous RacketCons. No publication date for this year’s recordings is specified.
““RacketCon is a public gathering dedicated to fostering a vibrant, innovative, and inclusive community around the Racket programming language.””
