alt Hacker Newsuv has been fantastic to use for little side projects. Combining uv run with `uv tool run` AKA `uvx` means one can fetch, install within a VM, and execute Python scripts from Github super easily. No git clone, no venv creation + entry + pip install.
And uv is fast — I mean REALLY fast. Fast to the point of suspecting something went wrong and silently errored, when it fact it did just what I wanted but 10x faster than pip.
It (and especially its docs) are a little rough around the edges, but it's bold enough and good enough I'm willing to use it nonetheless.

I agree uv is amazing, but it's not a virtual machine, it's a virtual environment. It runs the scripts on top of your OS without any hardware virtualization. The virtual environment only isolates the Python dependencies.
No more dependency problems with mkdocs I ran into before every other month:
uvx --with mkdocs-material --with mkdocs-material-extensions --with mkdocs-nav-weight mkdocs serve -a localhost:1337
Truly. uv somehow resolves and installs dependencies more quickly than pyenv manages to print its own --help output.
