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.

12to11 – run Wayland applications on an X server
Wayland works well on the Steam Deck because Valve controls the whole system. Because they have their own Wayland compositor (Gamescope), they're able to implement protocols to work around issues in Wayland without being delayed by the bureaucratic process of getting them approved. Here's an SDL pull request where a graphics developer at Valve discusses how two protocols necessary for good GPU performance haven't been added to Wayland yet so Valve added equivalent protocols to Gamescope as a workaround: https://github.com/libsdl-org/SDL/pull/9345
One thing to note is that the Steam Deck only uses Wayland for its fullscreen gaming mode. When you exit to its desktop mode (meant for running non-Steam software), it switches to X11.

C-Macs – a pure C macOS application
The linked project doesn't use any ObjC files at all. SDL2 has a bunch of Cocoa files[1] so you did use Cocoa even if unknowingly.

Revert "video: Prefer Wayland over X11 (take 2)"
Correct. It's explained here:
https://github.com/libsdl-org/SDL/pull/9345#issuecomment-201...
XWayland has special hooks into the compositors that normal wayland clients don't get.

BBC Basic returns on multiple platforms, open sourced
If that app ran in a 640x480 mode, memory accesses would be just as fast as the VGA applications 25 years ago, correct?
I think there's a lot more going on than that. Here's SDL's current pixel access code:

Games! How they write code for SDL (+ interview with the creator)
We use the code examples throughout the article. The ellipsis characters "...." in the code were added by the author of the article. You can find the source files on the official GitHub of libsdl. In addition, each fragment has a reference to a specific area in the code. By the time this article is published, many errors will have already been fixed thanks to the issues we opened (for example, here and there). However, the links in the examples point exactly to the code you see in this article. Not only do we enjoy teasing developers but we also like making their projects a little bit better!

Chip8 emulator
It's not that difficult, I recently started learning to use graphics APIs myself. OpenGL is for linux, etc., directx for windows and vulkan for all platforms. I read through a bunch of forums yesterday and decided to go for vulkan (here is a link to the sdk) for my next small projects because it can run on all platforms. I would recommend to watch a basic tutorial series (like this one) for the graphics api itself to get an understanding of whats going on. And on top of that I use SDL2 for eventhandling and ImGui for the graphical user interface. Here is a link to a guide for setting up vulkan on your platform in case you would go for it.

Black Triangles
It's fun to see the evolution in e.g. these examples of image loading for Dear Imgui:
https://github.com/ocornut/imgui/wiki/Image-Loading-and-Disp...
DirectX9 will even load the image for you, DirectX11 okay we get a few more structures to fill out, DirectX12 is where it goes off the rails and we are filling out a bunch of UNKNOWN DONT_CARE JUST_DO_IT. Then of course Vulkan is the one that gets the big fat "this probably won't actually work for you" warning.
I understand whats happening, but you know sometimes I just want to display a fucking image.

Dear ImGui: Bloat-free Graphical User interface with minimal dependencies
ImGui is engine/GPU agnostic
Themeing isn't a just a retained mode thing, you can do wonders with immediate UIs, even thought (dear)ImGui doesn't provide much, you can still do wonders: https://github.com/ocornut/imgui/issues/707#issuecomment-362...

PCSX2 Disables Wayland Support
Aside from bugs and driver issues, Wayland has some unfortunate design limitations. For example, Dear ImGui multi-viewports don't work because "Wayland doesn't let application read or write windows positions."
https://github.com/ocornut/imgui/wiki/Multi-Viewports
This is a feature available on Windows, macOS, and of course X11. Making choices like this means desktop Linux becomes even more of a weird island that nobody wants to support.
