video is up: Contributing to ArviZ and Open Source: Social and Technical Sides (Oriol Abril Pla)

ArviZ is a Python package for exploratory analysis of Bayesian models. It serves as a backend-agnostic tool for diagnosing and visualizing Bayesian inference.

In this webinar we go over both social and technical aspects we face when we contribute to ArviZ and to open source in general. We cover: finding an issue to work on, understanding how to work on it, to submitting the pull request and addressing the feedback received, and challenges faced. The talk will be focused on ArviZ, but it should also be useful to anyone interested in contributing to open source.
