@nprofile1q... @nprofile1q... I'm also sceptical in general as writing code is something I thoroughly enjoy. At least in private, at work things might be different. But there are def. areas where AI is helpful. E.g. chores like updating code to new language versions, mass cleanup, and I found it very helpful in setting up automated tests for legacy code. And also for documentation, esp. if you're not a native speaker.

@nprofile1q... No need to be sorry! I'm super grateful for all the the work you're doing with Dear ImGui!

If you wanna know if #Vulkan @nprofile1q... is the right graphics api for hobby developers (tl;dr: yes), you might find an answer in my #Vulkanised 2026 talk: https://www.youtube.com/watch?v=EshkHyYxb3A

Looking for a basic @nprofile1q... #Vulkan descriptor heap example? I've got you covered: https://github.com/SaschaWillems/Vulkan/blob/master/examples/descriptorheap/descriptorheap.cpp

Anyone want to test out small #webgpu page where I'm investigating performance of rendering many points, using regular GPU vs a compute shader? Here: https://aras-p.info/files/temp/webgpu/20250823_we...

When I started work on my @nprofile1q... #Vulkan C++ samples almost ten years ago I made some decisions that turned out to be non-optimal. Like not doing proper sync and pre-recording command buffers. Wanted to fix those for years now, but with ~100 samples and an active repo, that turned out to be not so easy. But finally managed to pull that off :)

Also did a write-up on this including details and a small retrospective on 10 years of Vulkan samples at https://www.saschawillems.de/blog/2025/08/15/fundamental-vulkan-samples-rework/

Finally finished adding @nprofile1q... shaders to all my (almost 100) @nprofile1q... open source samples and wrote a bit about it here:

https://www.saschawillems.de/blog/2025/06/03/shaders-for-vulkan-samples-now-also-available-in-slang/

tl;dr: I very much enjoyed this :)
