Michael #1: Marimo: “Future of Notebooks”

• via Matt Wilkie
• An open-source reactive notebook for Python
• Run one cell and marimo reacts by automatically running affected cells, eliminating the error-prone chore of managing notebook state.
• Marimo's reactive UI elements, like dataframe GUIs and plots, make working with data feel refreshingly fast, futuristic, and intuitive.
• Rapidly experiment with code and models
• Bind UI elements to Python values
• Pick-up-and-play design, with depth for power users
• See the FAQ

Brian #2: pytest 8.3.0 & 8.3.1 are out

• Real excited to get --xfail-tb flag added
  • This detaches xfail tracebacks from -rx/-ra (which was how it was pre-8.0)
• Keyword matching for marker expressions, that’s fun.
  • pytest -v -m "device(serial='123')"
• --no-fold-skipped allows for explit reporting of names of skipped tests
• Plus many more improvements, bug fixes, and doc improvements

Brian #4: bash-dungeon

• “This game is intended to teach new users how to use their shell in a fun and interactive way.”
• Just clone the repo and start exploring with cd, ls, and cat.
• First moves
  • cd bash-dungeon
  • ls
  • cd Enter
  • ls
  • cat parchment
• A fun way to learn some commands you might need and/or might have forgotten about.

Joke:

• 40 Million in in Series A Funding - may be a lot of reading, but I found it funny
  • Thanks to VM Brasseur for sharing this one.
• Also a few from pyjokes 0.7.2 (first new version since 2019)
  • If at first you don't succeed, call it version 1.0.
  • A product manager walks into a bar, asks for drink. Bartender says no, but will consider adding later.
  • Triumphantly, Beth removed Python 2.7 from her server in 2030. 'Finally!' she said with glee, only to see the announcement for Python 4.4.1
    • Although, if CalVer, PEP 2026, happens, that’ll just be Python 3.30.0.
