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.

How do I become a 3D printer power user? (the which CAD question)
I've been effective with OpenSCAD and FreeCAD.
OpenSCAD is good for enclosures: https://github.com/sbambach/MarksEnclosureHelper
and mechanical systems: https://github.com/prusa3d/Original-Prusa-i3
Don't think of it as a programming language; that will hurt you. Think of it as a specification language. That helped me.

Show HN: Dslcad a programming language and interpreter for building 3D models
there should be a support group. "Show me where OpenSCAD hurt you".
I wrote this: https://github.com/sbambach/MarksEnclosureHelper
I share your pain

Ask HN: What was your first open source contribution?
I did some early documentation of the Linux advanced networking capabilities when they came out in 2.2; it was widely cited for a while. I couldn't grow it effectively and others supplanted it reasonably quickly. [1]
I don't work easily with others so I tend to publish projects in hope they're useful enough for others, then never revisit or update them. My python arrays / mmap slicer module [2] got into FreeBSD ports for several years and I was told was used in some of the early dedicated media player things.
Source available that I can point to would be my OpenSCAD box script [3], which some kind soul has taken on after I left it.
These contributions are not much to compare to the value, and joy, that has been given to me by others in the form of their freely shared work; but I hope that by contributing in the same spirit that I have done my part to help improve the world, as well as sharing my joy in geeking out over stuff others may not care about.

Gimp 2.99.18 Released: The Last Development Preview Before 3.0
OCCT is definitely difficult.
I am almost as far as you can get from an expert but:
For example the TNP issue derives from OCCT (or something in the stack close to it, I am not exactly sure) not really handling face naming at all.
So if you want to avoid topological naming issues (which is a hard problem in CAD), you apparently have to do some work to track before and after and reconstruct your face naming.
https://wiki.freecad.org/Topological_naming_problem
https://forum.freecad.org/viewtopic.php?t=27278
Then there are various fairly entrenched issues to do with filleting and chamfering. Basically, both these operations will fail (in FreeCAD at least, but it's OCCT at "fault") if a chamfer or fillet would completely consume an existing edge. (It also sometimes creates impossible objects when filleting, or used to).
Booleans can be slow.
And more generally, it seems if you track the FreeCAD project that OCCT can be inscrutable when things fail; error messages aren't the greatest etc.
The flip side of OpenCascade is that it seems to be highly portable and has for example been compiled to JS with Emscripten for this astonishing thing:

It's a monumental open source project, for sure, and it's definitely not nothing that we have an open source CAD kernel; these are projects that perhaps have to extend beyond the working life of an individual developer if they are to be stable. And there are loads of projects built around it.
- Better OpenSCAD?

If you haven't seen it you may want to check out https://github.com/zalo/CascadeStudio
From what I see, it is exposing the OpenCascade base commands directly, versus your completely new DSL, but you might be interested in a way to implement your DSL on top of such an interface such as this which takes out a lot of the extra work of having a rendering interface, exports, etc, maybe.

Ask HN: If money was no object what software would you create?
It's nowhere near ready for primetime, but you should take a look at CascadeStudio (https://github.com/zalo/CascadeStudio)

Fornjot – The world needs another CAD program
FreeCAD is GUI-based though, not code-first like Fornjot. A better comparison would be CadQuery (https://cadquery.readthedocs.io/en/latest/intro.html) or Cascade Studio (https://zalo.github.io/CascadeStudio/), both of which are code-first and based on the same CAD kernel as FreeCAD.

- CascadeStudio: A Full Live-Scripted CAD Kernel in the Browser

Support for Javascript?
It is an actual example from CascadeStudio, but I haven't looked into it enough to know how what actually happens under the hood, but I assume the following:
- Playing with Mystery Curves (inspired by the whirlpool vase posted a couple days ago)
What are some alternatives?
pov2mesh - initial release
cadquery - A python parametric CAD scripting framework based on OCCT
gcodepreview - OpenSCAD library for moving a tool in lines and arcs so as to model how a part would be cut using G-Code.
psml - Python library for OpenSCAD
dslcad - DSLCad is a programming language & interpreter for building 3D models.
OpenJSCAD.org - JSCAD is an open source set of modular, browser and command line tools for creating parametric 2D and 3D designs with JavaScript code. It provides a quick, precise and reproducible method for generating 3D models, and is especially useful for 3D printing applications.
