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 have my users use OpenSCAD program over web with code hidden?

Fornjot 0.5.0 - Code-CAD in Rust
PS.: You may want to contact the guys from CadHub to add Fornjot to their list of code-CAD applications, and maybe take a look at the others I didn't mention if you haven't already. Also I must say that I'm not a dev of CadQuery.

advantages over JSCAD?
Toothpaste Squeezer at Cadhub.xyz [n.b. cadhub.xyz allows you to edit/render CadQuery/OpenSCAD without installing anything on your PC, not how I do my development but very good for showing others models]

Code CAD – Use code to create CAD models
the link for this post takes you to a OpenSCAD model, worth noting there are integrations it CadQuery and JSCAD too.

Have your Model Featured on CadHub
Hey folks, We recently updated the CadHub homepage https://cadhub.xyz/. Why am I telling you this? Right at the top there is a "hero model" and atm it's a coffee lid and I don't think it's ideal as It's a bit of an odd part in the sense that I don't think it represents a typical CAD model too well. So I'm asking for submissions if anyone would like to have their model featured. I think what would be best would be something reasonably simple but not too simple if you know what I mean.

I'm making a tool to render and download my openscad project. Feedback appreciated.
We absolutely want to add STL download to Cadhub. In fact since your box is hosted on Github, we actually want to build a Github integration/bot that builds and reproduces 3d artifacts with changes to master. But at the same time the customizer will be based on Github if so when you make changes to your repo the customizer will update too.

React.js component for rendering & exporting OpenJSCAD scripts
Super early days for me but I'm working on https://cadhub.xyz/, The idea is that it's a community sharing website for the code-cad community (think thingiverse cross codepen). I've got cascadeStudio working for the time being, but eventually, I'd like to add more. and this sounds like a easy way to integrate openJSCAD. (repo is here https://github.com/Irev-Dev/cadhub)an

Ask HN: What rabbit hole(s) did you dive into recently?
Can second this!
However, I would recommend https://solvespace.com! It hits a sweet spot between features vs complexity/learning effort.

Why large companies and fast-moving startups are banning merge commits
We use rebase on solvespace, along with sensible squashing so most commits along master are pretty self contained. You can see the clean history here:

A one line code change inside iOS made me waste 5 minutes
I changed a behavior to the "more standard" one because it felt obviously right. This was a 3 line change. But the was enough backlash right there in the pull request. So I spent a couple hours remembering how to add a configuration option to keep the old way for those guys:

RattleCAD
> If you like Linkage, you might also like Solvespace.
No, I mean Brent Curry's Linkage[1] bicycle design software, not David Rector's Linkage Mechanism Designer and Simulator[2].
You should read Wikipedia article.[0]
N.B. About SolveSpace, as I'm its experienced user[youtube,patreon], I may say next: yes, it could be used for bike mockup, as any other CAD, but it still has a lot of limitations and even does not export correct STEP files yet[3], and in FreeCAD such STEP could fixed only partially.[video]
So, for serious 3D CAD work I highly recommend use FreeCAD (and LibreCAD for 2D CAD work) instead of SolveSpace, and use SolveSpace only as a helper tool like a calc or as a notepad for noting ideas.
About Linkage Mechanism Designer and Simulator, it is only useful for planar (2D) kinematics analyze, and if You are looking an alternative for it take a look on Pyslvs[4], that is in part based on SolveSpace's solver.

Ask HN: What are some of the most elegant codebases in your favorite language?
C++ this file covers all the math for working with NURBS curves and surfaces:
https://github.com/solvespace/solvespace/blob/master/src/srf...
There is a lot more in other files - triangulation, booleans, creation - but the core math functions are there in very readable form.

The Great CPU Stagnation
>> Maybe somebody has statistical survey of how much of the existing deployed CPU core count is typically used?
My guess is very few cores are used on average. I did some testing with Solvespace to see which build options contributed most to performance:
https://github.com/solvespace/solvespace/issues/972
Obviously using OpenMP for multi-core was the big win. But what's not shown is that in typical usage (not the test I ran) if you're dragging some geometry around it will use all cores (in my case 4 cores / 8 threads) at about 50 percent utilization. That percentage probably drops as more cores are thrown at it due to Amdahl's Law. In other words, throwing double the cores at it will give a good boost to a lot of code that is already taking less than half the time (wall clock time, not CPU time).
We added OpenMP to a number of functions for significant performance gains. And in fact, any remining single-thread operation that gets the parallel treatment is likely to have a significant impact on overall performance since that is where most of the time is spent now. At this point we're more focused on features and bugs.
Algorithmic improvements are possible and I'd like to do those in the future, but they are much harder to do than sprinkling some #pragmas around critical loops. That will improve the scalability though, where multithreading really did not.
