Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Some Pain Point of Linux From a Long-time Windows User
Regarding toolchain managers, those developing software with Rust would use rustup, OCaml developers would use opam, Haskell GHCup, and Python with pyenv. Likwise, Rust already uses cargo for package management, Python can use pip and venv, cabal for Haskell, and opam still for OCaml.

Does anyone have an ETA on opam 2.2? I'm trying to pitch OCaml for a project that should be starting in roughly a year, but the lack of support for opam on windows is making it a really tough sell.
The project has a planning board for 2.2 on https://github.com/ocaml/opam/projects/2 and there are many active PRs on the repo. I wouldn’t hazard an accurate ETA but it is being actively worked on right now.

We feel it is too "me-too", and not Ada-specific enough [...] It doesn't, to us, feel like a truly Ada-native solution. Tangentially, the use of the word "crates" for the unit of management does little to evoke the kind of principled self-confidence Ada normally exudes.

Can't install graphics library on NixOs

Frustrated by lacking cross platform support (hoping to be wrong)
That being said, the experience on Windows could definitely be better. The bright side is that the community is aware of this and is making progress on improving it. If you're curious, you can take a look at some of the Windows-related plans for opam 2.2 (pdf).

Dune: build library and access it in another project and hide or make inaccessible private or implementation modules
With Dune, given the executable main, you would write the following dune file to use library mylib if it was published on Opam.
- Opam 2.0.8

How to install OCaml in WSL?
This is caused by bubblewrap requiring specific permissions when running in Docker containers. Disabling sandbox does make you install OCaml, but there is a risk of installation scripts of packages wiping home directory https://github.com/ocaml/opam/issues/3231

How to Create Virtual Environments in Python
Note that virtual environments assume you are using the same global version of Python. Often, this is not the case and additional tools like pyenv can be used alongside virtual environments when you need to switch between versions of Python itself on your local machine.

Manage your Python Project End-to-End with PDM
Note: Most modern systems will probably have a system environment that meets this requirement, but if yours does not or if you prefer not to install anything in your system environment (even if it's just PDM) check out asdf or pyenv to help install and manage additional Python environments.

Introducing Flama for Robust Machine Learning APIs
When dealing with software development, reproducibility is key. This is why we encourage you to use Python virtual environments to set up an isolated environment for your project. Virtual environments allow the isolation of dependencies, which plays a crucial role to avoid breaking compatibility between different projects. We cannot cover all the details about virtual environments in this post, but we encourage you to learn more about venv, pyenv or conda for a better understanding on how to create and manage virtual environments.

Is KDE Desktop really snappier than XFCE these days as claimed?
For Python, with your use case I would avoid system packages, no matter the distro. It sounds like it would be worth setting up pyenv and working exclusively with virtual environments.

Python Versions and Release Cycles
For OSX there is homebrew or pyenv (pyenv is another solution on Linux). As pyenv compiles from source it will require setting up XCode (the Apple IDE) tools to support this which can be pretty bulky. Windows users have chocolatey but the issue there is it works off the binaries. That means it won't have the latest security release available since those are source only. Conda is also another solution which can be picked up by Visual Studio Code as available versions of Python making development easier. In the end it might be best to consider using WSL on Windows for installing a Linux version and using that instead.
