Mono repos. You've heard the talks, you've read the blog post, maybe you've seen a few glimpses

into how Google or meta organize their massive code bases, but it's often in the abstract and

behind closed doors. What if you could crack open a real production mono repo, one with over a million

lines of Python code and over a hundred sub-packages, and actually see what's being built step by step using

modern tools and standards. Well, that's exactly what Apache Airflow gives us. On this episode,

I sit down with Yarrick-Pautouk and a Mogd-Sai, two of Airflow's top contributors to go inside

one of the largest open-source Python mono repos in the world and learn how they manage it with UVPyproject.comal

and the latest packaging standards.

So you can apply the same patterns to your own projects.

Talk Python a me, yeah, we ready to roll.

Upgrading the code.

No fear of getting old.

New frameworks in sight, geeky rap on deck.

Quark crew, it's time to unite.

We started in pyramid, cruising old school lanes, had that stable base, yes, sir.
