I've been away from Python for a bit, and project setup seems to have advanced a lot from one obviously correct way to do things. Where there was setuptools pip pip-tools venv, there is now `uv`, `pixi`, `poetry`, `pdm`, more?
Maybe because it's not obvious because I'm not dutch?
Any suggestion for a project that includes a little cython that is slowly being replaced with some maturin/pyo3 parts?
