jupyterWith has made significant improvements this year towards maintainability and ease of use. This talk will discuss those improvements and how you can quickly start creating reproducible Jupyter notebooks. JupyterLab is a popular web-based interactive development environment for notebooks, code, and data. However, it lacks the ability to lock dependencies and therefore lacks good reproducibility which jupyterWith overcomes by using Nix and Poetry. jupyterWith aims to be simple for researchers and developers and requires minimal understand of Nix and Jupyter to get started.
