Conda ≠ PyPI

Conda isn’t just another Python package manager-it’s a multi-language, user-space distribution system.

In this 3-part series, we explore the fundamental differences between conda and PyPI.

Part 1 is live now 👇

🏗️ Infrastructure wins that matter:

Isuru Fernando's breakdown of ABI3 conda support shows how "boring" backend improvements create massive downstream value.

Faster Python adoption, happier maintainers, lower costs - win-win-win!

Support for ABI3 packages in conda!

TIL you can configure VS Code's Python debugger to ask for CLI arguments on every execution.

The key option is:

```
"configurations": [
...,
"args": "${command:pickArgs}"
]
```

More details: code.visualstudio.com/docs/python/...

VS Code debugger configuration, `launch.json`.

Contents:

{
"version": "0.2.0",
"configurations": [
{
"name": "Python Debugger: conda CLI",
"type": "debugpy",
"request": "launch",
"module": "conda",
"args": "${command:pickArgs}"
}

This is how it looks for `conda-forge::python`:

Table of dependencies for Python, with linked package names, and version and build columns.

jaimergp @rjai.me · Apr 1

I've added a couple features to conda-metadata-app.streamlit.app.

1️⃣ If you check "Show dependencies as rich table" you'll get hyperlinked package names with separate columns for version and build strings.
2️⃣ The "Download artifact" link now reports the total size of the package.
