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, with live chat; organizers say recordings will be posted to YouTube after the conference. The supplied schedule lists five talks, though details for the final listed presentation are incomplete.
RacketCon 2026, a conference for people interested in the Racket programming language, is scheduled for Saturday, with doors opening at 8:30 a.m. PDT and the first talk beginning at 9 a.m., according to the event website. The program covers programming-language research and tools, and organizers say the conference will be livestreamed for people who cannot attend in person.
The day opens with Pat Hanrahan speaking at 9 a.m. on “On Notation.” The posted biography identifies Hanrahan as Stanford University’s Canon Professor of Computer Science and Electrical Engineering Emeritus, a former leader of RenderMan’s design at Pixar, a Tableau co-founder and the recipient of the 2019 ACM Turing Award. A break is scheduled for 10 a.m.
Talks resume at 10:30 a.m. with Fred Fu presenting “Type Inference With Logical Types For Untyped Languages.” The description says the work addresses challenges in type-checking programs that use macros and generated code, and outlines an ongoing prototype combining occurrence typing and algebraic subtyping. At 11:10 a.m., Lucas Myers is scheduled to discuss Pille, a Rhombus-based language with an LLVM-based compiler intended to support low-level and high-performance programming while retaining macro capabilities.
Lunch is listed for 11:50 a.m. and is provided, according to the schedule. The afternoon includes Mike Delmonaco on Treason, a prototype designed to preserve IDE services when errors prevent complete macro expansion, at 1:30 p.m.; and Pavel Panchekha on Herbie, a compiler for improving the floating-point accuracy of mathematical expressions, at 2:10 p.m. A break follows at 2:50 p.m. At 3:30 p.m., JJ is listed to speak about effect handlers in cio, a library for Racket and Guile Scheme. The supplied description ends mid-sentence, so it does not provide the full talk summary.
A Full Day on Racket’s Language Tools
The schedule brings together work on type systems, macro expansion, IDE support and numerical accuracy—topics that affect how developers build, analyze and maintain programs. Several talks describe prototypes or specific research tools rather than announcements of finished products; the event listing does not claim that the projects are generally available or ready for production use.
For attendees, the program offers a concentrated look at how Racket and related languages are being used to explore extensible programming and systems work. Remote access broadens that opportunity beyond people able to travel to the venue. The site says remote viewers can join the livestream and use live chat, with an optional paid ticket to support the stream.

How to Attend and Follow Along
RacketCon describes itself as a public gathering intended to build an inclusive community around the Racket programming language and engage both Racket users and the wider programming community. The event site says previous editions have also been streamed. It directs visitors to register for the 2026 conference and notes discounted early registration before September 13, but the supplied material does not state the year attached to that deadline or whether the discount remains available.
People unable to watch live can look for recordings on YouTube, which organizers say will be made available some time after the conference. The website also points readers to recordings of previous RacketCon presentations. No venue address or specific livestream link appears in the source material provided here.
““RacketCon is a public gathering dedicated to fostering a vibrant, innovative, and inclusive community around the Racket programming language.””
— RacketCon organizers
Date, Venue and Stream Details
The source identifies the event as taking place on Saturday but does not give the calendar date in the supplied text. It also does not name the venue, provide a livestream URL or specify when the recordings will be uploaded. The early-registration deadline is given as September 13 without a year, leaving its current status unclear.
The listing is incomplete at the end of the 3:30 p.m. talk description. It does not establish whether additional sessions follow, nor does it provide further details about the talks beyond the summaries shown. No attendance figures or other measures of the event’s reach are supplied.
Check the Organizers’ Event Listing
Attendees and remote viewers should consult the official RacketCon website for the calendar date, registration status, venue information and livestream access. The posted schedule gives the session times in PDT, beginning with doors at 8:30 a.m. and continuing through the 3:30 p.m. effect-handlers talk.
After the conference, organizers say they plan to post recordings on YouTube, but have not specified a release date in the supplied announcement. The next confirmed milestones are therefore the Saturday program and, at an unspecified later time, the promised recordings.
