Refresh an environment yaml file to current versions.

This script reads an existing `environment.yml` file (for Conda/Mamba
environments) and writes out a new file listing the same packages, but listing
all currently available versions of the listed packages.

For an alternate approach, that queries PyPI/Conda-Forge to gather the most
recent versions of all packages, see @yuvipanda's similar script at

Saving problems in JupyterLab 3.1.x

The notebook in this gist is meant to illustrate a problem we're experiencing with a notebook that often fails to save at all when attempting to write to it from a cloud-hosted bub.

See the saving-bug notebok for more details.

Polyglot Data Science with IPython & friends

Author: Fernando Pérez.

A demonstration of how to use Python, Julia, Fortran and R cooperatively to analyze data, in the same process.

This is supported by the IPython kernel and a few extensions that take advantage of IPython's magic system to provide low-level integration between Python and other languages.

See the companion notebook for data preparation and setup.
