Jessica Huang · UC Berkeley (opens in a new tab)
Free-threaded Python has been officially supported since 3.14. Jessica will review a year of adoption across the package ecosystem and discuss the work that remains before the free-threaded build can become the default.
Sat 5 Dec · 10:00
Elena Vasquez · NVIDIA (opens in a new tab)
Python packaging has changed more in the past three years than in the decade before, with a standard lockfile format, much faster installers and trusted publishing now in wide use. Elena will look at the problems that are still hardest to solve, particularly distributing packages that depend on GPUs and other specialized hardware, and at the proposals the packaging community is working on to address them.
Sun 6 Dec · 10:00
Christine Yu · Google (opens in a new tab)
CPython has included an experimental JIT compiler since version 3.13. This keynote explains how it builds on the specializing adaptive interpreter introduced in 3.11, how the copy-and-patch technique generates machine code, and where the project is headed. No background in compilers is assumed.
