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 and recordings planned for YouTube after the conference; the source does not provide a stream link or confirm the venue.
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 listed talk beginning at 9 a.m. The program includes presentations on type inference, low-level programming and IDE tools, and organizers say the event will be streamed for remote viewers.
The opening presentation, “On Notation,” is listed for 9 a.m. and will be given by Pat Hanrahan, the source says. Hanrahan is identified as a Stanford University professor emeritus in computer science and electrical engineering, a former leader of RenderMan’s design at Pixar, a Tableau co-founder and the recipient of the 2019 ACM Turing Award. The schedule lists a break at 10 a.m., followed by talks at 10:30 and 11:10 a.m.
At 10:30 a.m., Indiana University PhD candidate Fred Fu is scheduled to discuss “Type Inference With Logical Types For Untyped Languages.” The talk description outlines an ongoing prototype that combines occurrence typing and algebraic subtyping to address type-inference challenges in Racket programs involving macros. At 11:10 a.m., Northwestern University PhD student Lucas Myers will present Pille, described as a Rhombus-based language with an LLVM-based compiler intended to support low-level and high-performance programming while retaining Rhombus-style macros.
Lunch is listed for 11:50 a.m. and is provided, according to the schedule. Afternoon sessions include a 1:30 p.m. talk by Mike Delmonaco on Treason, a prototype designed to preserve IDE services when macro expansion encounters errors; a 2:10 p.m. presentation by University of Utah Associate Professor Pavel Panchekha on Herbie and floating-point accuracy; and a 3:30 p.m. talk by JJ on effect handlers in the cio library for Racket and Guile Scheme. A break is scheduled for 2:50 p.m.
A Program Focused on Language Tools
The schedule connects work on Racket and its language ecosystem with wider programming-language questions, including how to infer types, build compiler-backed languages and maintain useful editor features when code is incomplete or invalid. Those topics matter to developers who use macro-heavy languages, where code generation can make static analysis and IDE support harder.
The talks also span research prototypes and tools with practical aims. Fu’s presentation addresses type checking code produced by macros; Delmonaco’s concerns IDE support during incomplete macro expansion; and Myers’s talk considers systems programming beyond the Racket virtual machine. The program does not establish how mature or widely adopted these projects are, but it gives attendees a chance to hear their authors explain the approaches and limitations.
Remote access broadens the event beyond people able to attend in person. Organizers say there will be a livestream and live chat, while recordings are expected on YouTube sometime after the conference. The source says remote viewers may purchase a ticket to support the stream, making online participation available while also offering an optional way to contribute.

How Saturday’s Schedule Is Structured
The event page describes RacketCon as a public gathering intended to support an inclusive community around Racket and to reach people beyond that community. Its schedule runs from the 8:30 a.m. door opening through the listed 3:30 p.m. presentation, with talks, breaks and a provided lunch. The posted information does not give an end time for the conference.
The program includes subjects related to Racket, Rhombus and other language tools, rather than a single product announcement. Racket is a programming language, while Rhombus is also referenced in the talk descriptions. Herbie, the subject of Panchekha’s session, is described as a compiler that seeks more accurate floating-point expressions. The organizers also point readers to recordings of previous RacketCon presentations, though the source material does not specify when this year’s recordings will be posted beyond saying they will appear on YouTube after the event.
The event page asks attendees to register and mentions discounted early registration before September 13. Because the supplied listing does not state the Saturday’s calendar date or clarify the timing of that registration deadline relative to the conference, readers should check the official event page for current registration details.
““As in previous years, RacketCon will be streamed for those unable to attend in person.””

Date, Venue and Stream Details
The source labels the event day as Saturday but does not provide a calendar date or an in-person venue address. It also does not include a livestream link, access instructions or a specific time when the stream will begin. The schedule is given in Pacific Daylight Time, so remote viewers in other time zones will need to convert the listed times.
The page says recordings will be posted to YouTube “some time after the conference,” without a more precise timetable. It is also unclear from the supplied information whether every listed session will be streamed or recorded. The registration notice refers to a discounted rate before September 13, but does not give enough detail to establish the current ticket price or deadline status.
The talk descriptions present several projects as prototypes or research work. The source does not report independent evaluations, release dates or adoption levels for them. Their performance, availability and future development should not be inferred from the session summaries alone.
Check the Official Event Listing
People planning to attend or watch remotely should consult the official RacketCon website for the calendar date, venue, registration options and livestream access information. The posted schedule places the opening talk at 9 a.m. PDT on Saturday, after doors open at 8:30 a.m.
During the conference, organizers say viewers can use live chat, and remote participants may purchase a ticket to support the livestream. After the event, recordings are expected to be posted on YouTube, but the publication timing has not been specified.
Key Questions
When is RacketCon 2026?
The event page says it takes place on Saturday, but the supplied listing does not state the calendar date. It lists doors at 8:30 a.m. PDT and the first talk at 9 a.m. PDT.
Can people watch RacketCon remotely?
Yes. Organizers say the conference will be streamed and that live chat will be available. The supplied source does not include a stream link or viewing instructions.
What talks are on the schedule?
Listed subjects include notation, type inference for untyped languages, low-level programming with Pille, macro support for IDE services, floating-point accuracy with Herbie and effect handlers in cio.
Will the talks be available afterward?
Organizers say recordings will be posted on YouTube sometime after the conference. They have not provided a specific release date in the supplied information.
Where can attendees find registration information?
The RacketCon event page asks attendees to register and mentions discounted early registration before September 13. The supplied material does not confirm current ticket prices or whether that deadline remains open.
