I gave a talk at the Khronos Shading Languages Symposium about the 100+ graphics samples my team at work maintains, how we're moving them from GLSL to Slang, some neat things we get out of it (like pointers, reflection, and inline SPIR-V assembly), and how you can use it too!

The video's now up here: https://www.youtube.com/watch?v=p-7_LegG3EE&list=PLYO7XTAX41FNNPsKsqy2nf1cT-NwtQUIa&index=3

And I've reuploaded the slides here with speaker notes included:
- PDF: https://developer.download.nvidia.com/ProGraphics/nvpro-samples/slides/SLS26-nvpro-samples.pdf
- PPTX: https://developer.download.nvidia.com/ProGraphics/nvpro-samples/slides/SLS26-nvpro-samples.pptx

My team at AMD is looking for DCGPU assembly programmers in Netherlands or remote. Drop me a message if you're interested or know someone with relevant low-level optimization experience :)

New blog post about the GDB JIT interface. This brings me to 30 blog posts this year...!

The GDB JIT interface

GDB is great for stepping through machine code to figure out what is going on. It uses debug information under the hood to present you with a tidy backtrace and also determine how much machine code to print when you type disassemble.

@morten_skaaning @zeux Also worth checking out (somewhat more accurate models for Intel): uiCA - The uops.info Code Analyzer - https://uica.uops.info/ (select HTML output: Trace Table, Graph, Dependencies - you can then open the results under "Detailed Output"). There's a bunch of others, too: https://github.com/MattPD/cpplinks/blob/master/performance.tools.md#microarchitecture

Please provide support, where you can, to the people working across the world at EA, or at subsidiaries. I worked at io-interactive when the news broke that Square Enix was selling the company. It's a hell of a thing to go through, ontop of all the regular game development work you still need to do.
