The Best of Two Languages: Connecting C++ & Python with Cristián Maureira-Fredes

Have you ever wondered what astrophysics has in common with the software running in your car, your coffee machine, and NASA's internal tools?

In this episode, I sit down with Cristian Maureira-Fredes, a PhD in Astrophysics who decided to leave academia to join the software industry. Today, he is a Research and Development Principal Manager at The Qt Company, where he leads the team behind Qt for Python (PySide6) and the Qt Core team.
