Rich Input for Jupyter Cells

Elevator Pitch

Extend the Jupyter Notebook Format to offer an optional input field for all Cell types. This is an object which mirrors rich display outputs, providing data and associated metadata, both dictionaries keyed by MIME types.

Jupyter Clients that create and edit Notebooks MAY create this field, but MUST continue to emit the source field as the most-portable source-of-truth.

Resources

These are the resources mentioned during my talk, Accessibility and Inclusive Design, delivered for Project Jupyter on March 12, 2022.

How does JAX allocate memory on a TPU?

jnp.device_put(1) is deceptively simple to write in JAX. But on a TPU, what actually happens? How does a tensor containing the value 1 actually get onto a TPU?

Turns out, the answer is "C++", and a lot of it.

Negative Python user experience on Debian/Ubuntu

The user experience of Python on a minimal Debian or Ubuntu installation is bad. Core features like virtual environments, pip bootstrapping, and the ssl module are either missing or do not work like designed and documented. Some Python core developers including me are worried and consider Debian/Ubuntu's packaging harmful for Python's reputation and branding. Users don't get what they expect.

Reproducer

The problems can be easily reproduced with official Debian and Ubuntu containers in Docker or Podman. Debian Stable (Debian 10 Buster) comes with Python 3.7.3. Ubuntu Focal (20.04 LTS) has Python 3.8.5.
