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.

PicoGK is a compact and robust geometry kernel for Computational Engineering
Small in a relative sense compared to some larger codebase.
Here's a bit on Manifold:
https://github.com/elalish/manifold/wiki/Manifold-Library
and the author's blog is interesting:

Text-to-CAD: Risks and Opportunities
Wondering why no BRep support means it is not a CAD. It seems that OpenVSP doesn't use BRep but uses parametric surface [1]. I wonder if mesh-based modeling + some constraints solving will get you a CAD, or are there other requirements that I don't know? I only work on mesh processing library on my free-time and I don't know much about BRep.

My Unhealthy Relationship with Keyboards ⌨
Unhealthy relationship with keyboards? Comparing with the r/MechanicalKeyboards or r/ErgoMechKeyboards people this relationship is more like divorced...
I added python binding and ended up being on of the devs for https://github.com/elalish/manifold because OpenSCAD is too slow for my modeling (I am quite impatient). Optimizing my keyboard for months with more than 5 complete rebuilds to optimize my design (looks like this: https://i.redd.it/xtf0f54mt7ya1.jpg), and is afraid of open sourcing it because my code looks too bad :(

OpenSCAD's Web Playground got upgraded (still Alpha)
Now much faster and more stable thanks to the Manifold engine (https://github.com/elalish/manifold): in fact it is often faster than the last stable desktop release from https://openscad.org/.
Also much better code completion, and ships with a few examples from the various bundled libraries to get you started.

When I place down a CSGPolygon3D in this shape (haven't tried other shapes) it always opens a portal to hell, and it's not just in the editor, it's in the game too. Does anyone know what I can do about this?
At the end, they gonna replace it with ( elalish manifold.

Text-to-CAD: Risks and Opportunities
https://github.com/gumyr/build123d :
> Build123d is a python-based, parametric, boundary representation (BREP) modeling framework for 2D and 3D CAD. It's built on the Open Cascade geometric kernel and allows for the creation of complex models using a simple and intuitive python syntax. Build123d can be used to create models for 3D printing, CNC machining, laser cutting, and other manufacturing processes. Models can be exported to a wide variety of popular CAD tools such as FreeCAD and SolidWorks.
> Build123d could be considered as an evolution of CadQuery where the somewhat restrictive Fluent API (method chaining) is replaced with stateful context managers* - e.g. with blocks - thus enabling the full python toolbox: for loops, references to objects, object sorting and filtering, etc.*

NURBS for COMPAS: https://github.com/gramaziokohler/compas_nurbs :
> This package is inspired by the NURBS-Python package, however uses a NumPy-based backend for better performance.
> Curve, and Surface are non-uniform non-rational B-Spline geometries (NUBS), RationalCurve, and RationalSurface are non-uniform rational B-Spline Geometries (NURBS). They all built upon the class BSpline. Coordinates have to be in 3D space (x, y, z)
