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.

Best module for generate sketch
I was thinking about cadQuery or DrawSVG. But maybe you have a better idea ? I'm beginner in python (started on november ...)

Synth Printer: 3D printed synth panels with simple Python code. Give me early feedback?
Last few months, I've made over 20 3D printed panels using the CadQuery Python library. Its syntax is pretty complex, so every time I wanted to make a panel, I'd just copy-paste bits and pieces from my previous panels. In the process, I learned what work and what doesn't, and I thought it was time to polish up this system to share it with others.

Pipeline to automate the process from creating 3d objects to start a print job
I am currently developing a pipeline for creating STL files, slice them and create a print job based on it. My setup at the moment is an Ultimaker S5, which offers a simple REST-API, for example starting a job with a G-Code or UFP file. I am using the cadQuery library for creating parametrized 3d shapes and export them as a STL file. I want to use the CuraEngine CLI interface (Backend for Cura) for slicing or their library libArcus (python bindings) but there is literally no documentation or any kind of examples, except the source code. There is also the prucaSlicer, which also offers a CLI interface for creating G-Code, but no support for the Ultimaker S5.

What is the end purpose of your OpenBSD system?
CadQuery would be a closer alternative to OpenSCAD. Not sure if itβs available on OpenBSD.

Show HN: MarkovJunior, PPL based on pattern matching and constraint propagation
That thesis is really fun, but it will take me a couple weeks to digest. Before it even starts I see Pat Hanrahan, who is one of the nicest most creative people I have met in CS (), I know this going to be good.
A fantasy of mine is to have a bag of arbitrary constraints and behaviors of agents that exercise the system. One could sketch a building, model the behavior of people that will use it and let the system run, doing backwards and forwards inference to evolve a structure that makes those agents satisfied across lots of criteria. The designer if they are still called that, can select designs they like and the system can use that as a seed or test oracle. Virtual cows, cow paths and evolvable structures wrt those cow paths.

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:
https://zalo.github.io/CascadeStudio/
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.

Show HN: Dslcad a programming language and interpreter for building 3D models
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.

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:

To design a new mount for the Chimera 2in2out for the Ender 3, I rebuilt the carriage assembly in OpenScad and partyl QCad.
π A good sketching mechanism is in my opinion one thing that's lacking in all of the code-cad projects. The closest they have is polygons with a few extra features (they might include filleting corners https://github.com/zalo/CascadeStudio/discussions/50).
