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.

Baldurs Gate 3 wont work with Vulkan
If this works then it might actually be a game bug and the game I guess passes invalid shaders when the cache exists... but it seems to work fine on windows vulkan drivers. You could try to run the game with https://github.com/KhronosGroup/Vulkan-ValidationLayers

Help a noob out: compute shader synchronization/scheduling
For debugging these kinds of issues, I would recommend enabling the synchronization validation layer.
-
Validation Layers crash Vulkan (on Android)
I would use the debugger to produce a stack trace and look into the validation layers source code. https://github.com/KhronosGroup/Vulkan-ValidationLayers Then I would either file an issue or make a PR there.
-
Managing bindless descriptors in Vulkan
Currently validation layers might generate false-positive errors: https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/3450
-
Validation layers sporadically cause extended dynamic states to crash.
A'rightey... I was able to reproduce this issue with Sascha Willems basic triangle example, so I am fairly certain, that this is a bug. I've opened an issue.

Need help using Vulkan-ValidationLayers as CMake FetchContent
I am really at loss here, I found this issue but it doesn't really help me (I am starting to doubt it's even possible, maybe I'm a clown and doing it wrong...)
- Anyway to get QueueSubmit to wait on Timeline Semaphores?
-
Synchronization layers being triggered by a subpass dependency
Can you post a reproduction case at https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues so we can take a look at it.

Emacs Is Not Enough
Which is why a GPU debugger with frame tracing is so much better option.
By the way, there are actually ways to expose a print function on shader code, provided there is driver support.

Is here a way to turn VkResult into C string?
Huh yeah. Looking through the header the function you want works with c but there are others using c++ features. The reason given is understandable.

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.
