Why Python developers just use Postgres with Dawn Wages

Talking Postgres with Claire Giordano

When I found out that Django developer and Python Software Foundation chair Dawn Wages has a chapter in her upcoming Domain-Driven Django book called “Just Use Postgres”, I knew we had to get her on the show. In this episode of Talking Postgres with Claire Giordano, Dawn breaks down why so many Python and Django developers have such an affinity for Postgres. And we dive into the Djangonaut Space mentoring program (where contributors launch), learn why “free as in puppies” beats “free as in cake” for open source vibes, and dig into why Python is the second-best language for everything.
