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.

Looking for a poor man's AutoCad
LibreCAD, OpenSCAD (more script based and more for solids), FreeCAD.

If I don't use Windows or Mac and only use Linux, will I run into a lot of compatibility issues?
CAD options on Linux are more limited than windows or mac but they do exist. The industry standard for 2d CAD files is the .dxf file format. I use LibreCAD. https://librecad.org/ The UI is a little clunky and eccentric in places but it is feature complete for 2d CAD drawings.

Any drawing app other than autocad na easy to access?
Try https://librecad.org/

Open source alternative that is most similar to AutoCAD?
LibreCAD similar UI, only for 2D
-
Windows / MacOS - Home/garden design
You could also try out free AutoCAD alternatives like libreCAD (2D), or brlCAD (2D&3D, I believe)

Everything you need to know about CAD humble bundle
It seems like a low risk purchase for $1, however, there are free options available too such as https://librecad.org/ . Or see https://www.reddit.com/r/humblebundles/comments/117ki1c/comment/j9v0v37/?utm_source=reddit&utm_medium=web2x&context=3 for an older Autocad clone. Beckercad 2D seems like a niche product so I would probably invest my time learning something that is more mainstream.

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.
