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.

Dark UI / Dark Mode
How do i enable the UI to be dark like in this post https://gitlab.com/kicad/code/kicad/-/issues/3923

Can someone review my schematic and PCB?
For point 1, are you sure you're using the latest KiCad version? I know there was a bug in de software before, which caused this exact problem. But that's already from a long time ago: https://gitlab.com/kicad/code/kicad/-/issues/6447

KiCad Project Makefile
The first thing of thought of with kicad-cli is a Makefile include. It's developed into kicad-makefile. It does everything I want, except DRC/ERC but hopefully that will come. Perhaps others on here will find it useful and can contribute. See the README for info on how to use it and integrate with GitHub actions.

Python errors with 7
Not sure if the devs watch these forums, but if you want this issue solved I recommend raising the issue on Gitlab https://gitlab.com/kicad/code/kicad/-/issues (where the devs will definately see your bug report)

KidCad 7 won't snap to objects on non-active layer
There's an open feature request for an explicit multi-layer snap mode: https://gitlab.com/kicad/code/kicad/-/issues/6266
- A little bit offtopic kicad7 released

Kicad 7 released
- https://gitlab.com/kicad/code/kicad/-/issues/4084
- KiCad 6.0.11 was just tagged in the source repo. Expect a new bugfix-release in a day or two!

Just a simple plugin to create rounded rectangles
If you're really using the nightly build, you might not need that plugin. https://gitlab.com/kicad/code/kicad/-/issues/4742 seems to have a patch for that already. However it's targeted at kicad 8.0

If you can't reproduce the model then it's not open-source
I think the process of data acquisition isn't so clear-cut. Take CERN as an example: they release loads of data from various experiments under the CC0 license [1]. This isn't just a few small datasets for classroom use; we're talking big-league data, like the entire first run data from LHCb [2].
On their portal, they don't just dump the data and leave you to it. They've got guides on analysis and the necessary tools (mostly open source stuff like ROOT [3] and even VMs). This means anyone can dive in. You could potentially discover something new or build on existing experiment analyses. This setup, with open data and tools, ticks the boxes for reproducibility. But does it mean people need to recreate the data themselves?
Ideally, yeah, but realistically, while you could theoretically rebuild the LHC (since most technical details are public), it would take an army of skilled people, billions of dollars, and years to do it.
This contrasts with open source models, where you can retrain models using data to get the weights. But getting hold of the data and the cost to reproduce the weights is usually prohibitive. I get that CERN's approach might seem to counter this, but remember, they're not releasing raw data (which is mostly noise), but a more refined version. Try downloading several petabytes of raw data if not; good luck with that. But for training something like a LLM, you might need the whole dataset, which in many cases have its own problems with copyrights…etc.

Interactive GCC (igcc) is a read-eval-print loop (REPL) for C/C++
The odd part is that this is not just for fun. For many physicists when I was at CERN, a C++ REPL was a commonly used tool to interactively debug analyses to such a degree that many never compiled their code. Back then, I believe, it was some custom implementation included in ROOT (https://root.cern/). I even went out of my way to write C++ code compatible to it just so it could run with this implementation, otherwise some colleagues weren't interested in collaborating at all.

Stable Diffusion in pure C/C++
That Python ML code is calling C++ code running in the GPU, one more reason to use C++ across the whole stack.
CERN already used prototyping in C++, with ROOT and CINT, 20 years ago.
https://root.cern/
Nowadays it is even usable from Netbooks via Xeus.
It is more a matter of lack of exposure to C++ interpreters than anything else.

cppyy Generated Wrappers and Type Annotations
I'm a user of CERN's ROOT (https://root.cern/) and while I'd usually write in C++, I've been trying to write as much Python as I can recently to get a bit better in the language.

Span: how to cast pointer of pointer to other types?
I'm dealing with a C++ software called ROOT made by CERN, which is, if I'm not wrong, the only C++ API that we could use for data analysis such as plotting histograms, fitting multi-parameter functions and storing data in the size of TB to the disk and many more. That's the only reason why physicists still stick to this software. you can check here .
