I'm currently revising the core-library-focused @PassageMath Developer's Guide into a more comprehensive and inclusive Contributor's Guide.
Feedback, contributions, and suggestions are most welcome:

Quite fascinated by the technology in today's world.

Time really does fly.

I have now started the @passagemath upstream campaign: Making projects aware of the pip-installable passagemath distributions that use the projects' packages, redistribute them in binary wheels on #PyPI, and provide #Python interfaces for them.

1 year ago, I wrote about the intrinsic conflict between abstraction and attribution in building mathematical software.

passagemath 10.5.33 now provides binary wheels on PyPI also for musllinux on aarch64 (ARM).

@pasternak @helenaeverley @ghoshal @veervda How does this work?

[Matthias Köppe @mkoeppe_math]

Powers of two: My contributions to #SageMath (since 2015) → passagemath (since 2024) quietly exceeded 2¹⁴ commits at the end of 2024. The main branch of the passagemath repo crossed the threshold of 2¹⁷ commits around the passagemath-10.5.4 release.

I sent PRs to 50 #SageMath user projects in January, adding support for running in plain #Python using the modularized passagemath distributions. Results so far: see below for an overview...

[PassageMath @passagemath]

The 67 pip-installable packages of passagemath are now listed under the #PyPI organization "passagemath" for easier access.

The new passagemath 10.5.23 release is available on PyPI and GitHub. It is up to date with SageMath 10.6b6 and supports Python 3.9–3.13.

Opening the doors of perception.

To the unconvinced, maths begins and ends with numbers and equations. But as Hugo Duminil-Copin explains, they are merely the launching pad for a mathematical world that we can all appreciate, and even love.
