RacketCon 2026 is scheduled for Saturday, with doors opening at 8:30 a.m. PDT and talks beginning at 9 a.m. The conference website says remote viewers can watch a livestream, join live chat and later find recordings on YouTube; the supplied schedule lists talks through an effect-handlers session at 3:30 p.m.
RacketCon 2026 is scheduled for Saturday, bringing together people interested in the Racket programming language for a program of talks on type systems, low-level programming, macros, floating-point accuracy and effect handlers. The conference website lists doors opening at 8:30 a.m. PDT, with the first talk at 9 a.m., and says the event will also be streamed for people unable to attend in person.
The schedule opens with “On Notation” at 9 a.m. by Pat Hanrahan, identified by the conference as Stanford University’s Canon Professor of Computer Science and Electrical Engineering Emeritus. The site’s biography says Hanrahan 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 beginning at 10:30 a.m.
Fred Fu’s 10:30 a.m. presentation, “Type Inference With Logical Types For Untyped Languages,” concerns a prototype system for handling patterns in Racket programs that can pose difficulties for Typed Racket. At 11:10 a.m., Lucas Myers is scheduled to discuss Pille, a Rhombus-based language using an LLVM-based compiler for low-level and high-performance programming. Lunch is listed at 11:50 a.m. and is described as provided.
The afternoon program includes Mike Delmonaco on the Treason prototype and IDE services for programs with macro-expansion errors 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. After a 2:50 p.m. break, JJ is listed to speak at 3:30 p.m. about effect handlers in cio, a library for Racket and Guile Scheme. The supplied schedule ends with that entry.
A Full Day for Racket Developers
The schedule reflects a conference focused not just on using Racket, but on the language tools and research around it. Sessions address practical concerns such as type inference in macro-heavy code and IDE support when programs are incomplete, alongside broader work on low-level programming and numerical accuracy. For attendees, the program offers a concentrated view of projects and ideas being developed in and around the Racket ecosystem.
Remote access extends the event beyond people who can be at the venue. The organizers say the livestream will have live chat, and viewers may purchase a remote participation ticket to support the stream. Recordings are also expected to be posted on YouTube after the conference, though the site does not provide a release date.

How the Saturday Program Is Set
The conference describes RacketCon as a public gathering intended to foster an inclusive community around the Racket programming language and to reach people beyond that community. Its website says previous years also offered streaming, and points visitors to recordings of earlier presentations. The 2026 event continues that format, pairing an in-person schedule with online viewing.
The listed talks span work on Racket, its gradually typed counterpart Typed Racket, and Rhombus, as well as projects and programming-language concepts connected to them. The source presents several sessions as research, prototypes or introductions; it does not say that the projects discussed are finished products or ready for general use.

Date, Venue and Remaining Schedule Details
The supplied conference page identifies the event as taking place on Saturday but does not give a calendar date or venue in the material provided. It also does not specify livestream access instructions, whether remote participation requires a ticket to watch, or the amount of any ticket price. The page says remote viewers have the option to purchase a ticket to support the livestream, but does not describe other access terms.
The schedule excerpt ends with JJ’s 3:30 p.m. session, so it does not establish whether that is the final event of the day or whether additional talks, activities or closing remarks are planned. The organizers give no specific date for uploading recordings. These details should be checked against the conference website as the event approaches.

Saturday Talks and Online Access
On Saturday, the conference is scheduled to open its doors at 8:30 a.m. PDT, with the first presentation starting at 9 a.m. Attendees can follow the listed program through the afternoon, while remote viewers can look for the livestream and live chat information from the organizers. The conference website also invites registration and refers to discounted early registration before September 13, but the supplied material does not state the calendar year or explain whether that offer remains available.
After the event, the organizers say recordings will be made available on YouTube some time after the conference. No more specific publication timetable is given.
