Meta Engineers Talk Python 3.12 Contributions
Python 3.12 shipped with several features developed by engineers at Meta, and the company is now pulling back the curtain on that work. On the Meta Tech Podcast, host Pascal Hartig sits down with software engineers Itamar Oren and Carl Meyer to discuss their teams' contributions to the release.
The conversation covers the new hooks that enable custom JITs like Cinder, the Immortal Objects project, type system improvements, faster comprehensions, and other changes that landed in the latest Python version. Oren and Meyer explain both the technical reasons behind building these features and how they collaborated with the broader Python community throughout the process.
The episode is available on the Meta Tech Podcast feed and can be found on Spotify, Apple Podcasts, PocketCasts, Castro, and Overcast. Feedback can be sent via Instagram, Threads, or X, and those interested in similar work can explore opportunities on the Meta Careers page.
