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

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.
