alt Hacker NewsThis week I was wondering whether using uv for managing Python versions is a good idea.
From their website [1]
> Python does not publish official distributable binaries. As such, uv uses distributions from the Astral python-build-standalone project. See the Python distributions documentation for more details.
It points to this GitHub repo https://github.com/astral-sh/python-build-standalone which mentions this other link https://gregoryszorc.com/docs/python-build-standalone/main/r...
If I understand correctly, the source code for building Python is not fetched directly from python.org. Not so sure how secure is that.
I have the same concern for asdf [2]. However, they use pyenv [3] which, I think, feels more official.
Can someone clarify this? Which tool is better/more secure for installing python: uv or asdf?

I'm really not worried about `uv` and `cpython` -- their processes are robust, their response times fast, and (now) their funding significant
I'm worried about, say, `mdformat` (a widely used formatter mostly maintained by one person in their spare time), not to mention some super-specific dependency that hasn't been updated in years and is 3 levels deep in your dep tree. I really don't want to pin & manually approve every single update for an app that's under active development, but it's beginning to look like that's mandatory for any serious app.
In the meantime, I've gotta go get my API keys out of my unencrypted `.env` files! Getting burned on a large, consumer-facing webapp would be embarrasing but logical, but losing hundreds to thousands of dollars because of some indirect dependency of some silly one-off demo repo that just happens to be on the same host & system as my `.env`s... oof.
Anyone know if OAI or Anthropic will refund you if you get your keys stolen like this? Or is it user error?
i mean... uv is already a binary you run on your computer to manage python binaries, packages (and any binaries with those), systemwide tools etc; how much does it change whether they build the python binaries or someone else?

python-build-standalone fetches CPython sources directly from python.org[1]. I don't even know where else we would get them from!
