RacketCon 2026 is scheduled for Saturday, with doors opening at 8:30 a.m. PDT and talks beginning at 9 a.m. The event will be streamed, and recordings are expected to be posted to YouTube after the conference; the supplied schedule lists sessions through a 3:30 p.m. talk.
RacketCon 2026 is scheduled for Saturday, bringing together people interested in the Racket programming language for a day of talks, with a livestream available for those who cannot attend in person. The published schedule sets doors to open at 8:30 a.m. PDT and the first presentation to begin at 9 a.m.; the program ranges from type systems and low-level programming to floating-point accuracy and effect handlers.
The day begins with Pat Hanrahan’s 9 a.m. talk, “On Notation.” The event page identifies Hanrahan 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 listed for 10 a.m., followed by talks at 10:30 and 11:10 a.m.
At 10:30 a.m., Fred Fu will discuss type inference for untyped languages, focusing on challenges that arise when Typed Racket programs use macros that generate complex code. The listing describes an ongoing prototype that combines occurrence typing and algebraic subtyping. At 11:10 a.m., Lucas Myers will present Pille, a Rhombus-based language with an LLVM-based compiler intended to explore low-level and high-performance programming while retaining Rhombus-style macros.
Lunch is provided at 11:50 a.m. The afternoon schedule lists Mike Delmonaco on Treason, a prototype aimed at connecting macros with IDE services, at 1:30 p.m.; Pavel Panchekha on Herbie and floating-point accuracy at 2:10 p.m.; and JJ on effect handlers in the cio library at 3:30 p.m. A break is scheduled for 2:50 p.m. The supplied program ends with the 3:30 p.m. session.
A Program Spanning Racket’s Reach
The agenda shows how the gathering connects work on Racket’s language features with broader programming problems. Several sessions focus on tools and abstractions that affect how developers write, analyze and maintain code: type inference for macro-heavy programs, IDE support when macro expansion encounters errors, and techniques for improving numerical accuracy.
The Pille presentation also addresses a potential reach beyond conventional Racket applications. Its description says the project explores low-level and high-performance uses, including environments where the Racket virtual machine may be limiting. That is the project’s stated aim, not evidence in the event listing that Pille is production-ready or already deployed on constrained devices.
Remote access broadens the event beyond people able to attend at the venue. The organizers say the conference will be streamed, with live chat available and an optional remote participation ticket for viewers who want to support the livestream. The event page does not specify the stream platform or provide a link in the supplied material.

How the Saturday Schedule Is Set
RacketCon describes itself as a public gathering for the Racket community, intended to welcome people interested in the language and engage the wider programming world. The 2026 page asks people to register and mentions discounted early registration before September 13, but the supplied information does not give the conference’s calendar date or clarify whether that deadline has passed.
The organizers say, as in previous years, the program will be streamed for people who cannot attend in person. They also say recordings will be made available on YouTube some time after the conference. Previous RacketCon presentations are available through links on the event page, according to the organizers. The schedule and descriptions provided here establish the announced program, rather than independent verification of individual project results.
“RacketCon is a public gathering dedicated to fostering a vibrant, innovative, and inclusive community around the Racket programming language.”
— RacketCon organizers
Date and Viewing Details Still Missing
The source identifies the event as taking place Saturday but does not state the calendar date, venue address or registration link in the supplied material. It also does not say whether registration is still open or whether the early-registration offer ending before September 13 remains available.
The livestream platform, viewing link and any access instructions are not included. The page says recordings will be posted to YouTube after the conference but gives no publication timeline. The supplied schedule also stops at the 3:30 p.m. talk, so it is unclear whether that is the final session or whether later activities are planned.
Saturday Talks and Later Recordings
On Saturday, the listed program is due to begin with doors at 8:30 a.m. PDT and Hanrahan’s talk at 9 a.m., followed by the scheduled presentations and breaks. People planning to attend remotely will need the organizers’ current stream information; the supplied announcement confirms a livestream and live chat but does not include access details.
After the conference, RacketCon says it plans to publish recordings on YouTube, though no release date is specified. The event page is the cited source for any updates to the schedule, registration information and remote-viewing instructions.
Key Questions
