Michael #1: PyPI+

Very nice search and exploration tool for PyPI
Minor but annoying bug: content-types ≠ content_types on PyPI+ but they are in Python itself. Minimum Python version seems to be interpreted as max Python version.
See dependency graphs and more
Examples

Brian #2: uv-ship - a CLI-tool for shipping with uv

“uv-ship is a lightweight companion to uv that removes the risky parts of cutting a release. It verifies the repo state, bumps your project metadata and optionally refreshes the changelog. It then commits, tags & pushes the result, while giving you the chance to review every step.”

Michael #3: How fast is 3.14?

by Miguel Grinberg
A big focus on threaded vs. non-threaded Python
Some times its faster, other times, it’s slower

Brian #4: air - a new web framework built with FastAPI, Starlette, and Pydantic.

An very new project in Alpha stage by Daniel & Audrey Felderoy, the “Two Scoops of Django” people.
Air Tags are an interesting thing.
Also Why? is amazing
- “Don't use AIR”
- “Every release could break your code! If you have to ask why you should use it, it's probably not for you.”
- “If you want to use Air, you can. But we don't recommend it.”
- “It'll likely infect you, your family, and your codebase with an evil web framework mind virus, , …”
