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.

Kinematic Coupling (Maxwell) Assembly with FreeCAD
If the general python API isn't enough the assembly3 docs have an interesting example which might give you some ideas for moving objects along within their constraints.

A few thoughts on Freecad vs Fusion 360
I think Realthunder's branch may have midpoint constrain you're looking for (https://github.com/realthunder/FreeCAD_assembly3/issues/51).
-
How to avoid breaking things when modifying existing elements in Parts Design?
Also if you use this fork of freecad: https://github.com/realthunder/FreeCAD_assembly3/releases its much better at letting you attach sketches to faces without it borking things.

Regularly Updated Summary of Merging of Realthunder's FreeCAD Link Branch into Topological Naming Branch?

- How do you prefer to place sketches on objects?
-
total FreeCAD newb, can't edit legacy parts
FreeCAD is still in development and you may have a mismatch of versions. Try .17, .18, .19, and .20 dev versions and try to find the one that doesn't show empty sketches. It may have even been made with the RealThunder branch.

Are there any free CAD/3D modeling programs that work with 3D printers?
Fusion 360 is probably the best choice to start. It's free and easy to use. But there are quiet heavy limitations as autodesk changed their licenses. I recently switchend from fusion to freeCAD and I'm pretty happy with it. I highly recommend Linkstage3, a freeCAD fork by a guy called realthunder. https://github.com/realthunder/FreeCAD_assembly3/releases
-
Why Does This Happen?
If you haven't already, take a look at Realthunders Linkstage branch. That's the one I usually use, although it can lead to adapting design practices that are not ideal.

-
Is it possible to reference a feature's position within a linear pattern?
FreeCAD fork linkstage3 supports expressions for patterns which I imagine would allow you to do this.

manim – A community-maintained Python framework for creating mathematical animations
- I'm new to try manim and it met some questions TypeError: __init__() got an unexpected keyword argument 'line_join'

Old blog of Matt Henderson, beautiful math animations
I recently wanted to make something similar and I completely fell in love with https://www.manim.community/ created by 3B1B.

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)

Ask HN: What would you show an interviewer if they asked you for code samples?
A template language that I wrote for generating HTML. Meant to be included as a C++ library. https://github.com/Ghoti-io/Tang
Plenty of other C++ code of mine is on Github (such as a bunch of utility stuff, a thread pool, and a HTTP server that I'm writing from scratch), even though I would only call myself an intermediate C++ programmer. I just happen to like the language.
Or, if I had to throw other stuff into the mix, a fairly recent patch to Manim (Python) that got accepted (https://github.com/ManimCommunity/manim/pull/3155).
If I were really pressed, I would dig up a lot of my Drupal (PHP) stuff that I did years ago.

What are you rewriting in rust?
I would love to have this https://github.com/manimCommunity/manim written in Rust. There have been previous attempts (bevy_manim and another one using nannou) but all of them are outdated
