The sticking point for me is the way tools like uv and poetry build everything around the idea of a "project".

This was always my issue with pip and venv: I don’t want a thing that hijacks my terminal and PATH, flips my world upside down and makes writing automated headless scripts and systemd services a huge pain. When I drop into a Node.js project, usually some things have changed, but I always know that if I need to, I can find all of my dependencies in my node_modules folder, and I can package up that folder and move it w…

For not having to call 'source ...' in a Dockerfile, if you use the python executable from the virtualenv directly, then it will be as if you've activated that virtualenv.

This works because of the relative path to the pyenv.cfg file.

Post like these aptly describe why companies are downsizing in lieu of AI assistants, and they are not wrong for doing so. Yes, Python is "slow". The thing is, compute is cheap these days and development time is expensive. $1000 per month is consi…

>$1000 per month is considered expensive as hell for an EC2 instance, but no developer would work for $12000 a year.

If using Python instead of what we use, our cloud costs would be more than double.

And I can't go to CEO and CFO and explain to them that I want to double the cloud costs (which are already seen as high).

Then, our development speed won't really improve because we have large projects.

That being said, I think using Python for scripting is great in our case.

Earlier quoted context omitted.

You might be interested in pixi, which is roughly to conda as uv is to pip (also written in Rust, it reuses the uv solver for PyPI packages)

I wish the Python ecosystem would just switch to Rust. Things are nice over here… please port your packages to crates.

I've never used a more hostile language than rust. Some people hate python and I can't understand why but such is life. One mans meat....

> But then I remember that Python is dog slow compared to other languages with comparable ergonomics and first-class support for static typing, and...idk it's a tough sell. Case in point: uv itself is not written in Python. It's a Rust tool. It always amazes me when people work on an ecosystem for a language but then don't buy enough into that to actually use it to do the work. Avoidance of dogfooding is a big red fl…

There’s this thing where you work to requirements instead of picking things on vibes, it’s called engineering.

(off topic) The code chunks in the article use a ligature font, so ">=" is rendered in a way that makes you stop to think how to type it - which is especially confusing since the context is not exactly math. Down with ligatures and extra cognitive load!

Conda is open source. Not sure what you mean about an EULA. There are some license agreements if you use Anaconda, but if you just use conda-forge you don't have any entanglements with Anaconda the company. (I agree the nomenclature is confusing.)

I wish we had a language that had the syntax of Python (notably including operator overloading, which is absolutely critical for neural networks, ML, data science and numerical computations), the performance, compile times and concurrency support of Go, the type system flexibility of Typescript, and the native platform integration of C/C++.

There's Mojo, but it's been a while since I've heard anything about it.
