Brian #1: Deprecations via warnings

• Deprecations via warnings don’t work for Python libraries
  • Seth Larson

Michael #2: docs

• A collaborative note taking, wiki and documentation platform that scales. Built with Django and React.
• Made for self hosting
• Docs is the result of a joint effort led by the French 🇫🇷🥖 (DINUM) and German 🇩🇪🥨 governments (ZenDiS)

Brian #3: PyAtlas: interactive map of the top 10,000 Python packages on PyPI.

• Florian Maas
• Source: https://github.com/fpgmaas/pyatlas
• Playing with it I discovered a couple cool pytest plugins
  • pytest-deepassert - Enhanced pytest assertions with detailed diffs powered by DeepDiff
    • cool readable diffs of deep data structures
  • pytest-plus - some extended pytest functionality
    • I like the “Avoiding duplicate test function names” and “Avoiding problematic test identifiers” features

Michael #4: Buckaroo

• The data table UI for Notebooks.
• Quickly explore dataframes, scroll through dataframes, search, sort, view summary stats and histograms. Works with Pandas, Polars, Jupyter, Marimo, VSCode Notebooks

Joke: Fixed it!
