Now I see that #vibecoding is a good educational tool if you are lazy but still get pleasure from using your brain.

The first version was a slow naive implementation. An LLM optimized it with #bitwise tricks, but was bad at explaining them. Another LLM explained the algorithm with a guide on Single Instruction Multiple Data (within-a-register) processing.

I've never encountered these tricks in my working routine and probably would have never tried them without a practical need. Now I'm at least aware of them, thanks to playing with evil ai. Everything at zero cost.

Tối ưu thêm #Java SwissTable: Khắc phục tràn hồ sơ và thử nghiệm #SWAR. Tác giả kiểm tra lại phần #hashmap nhanh nhất bằng cách sửa lỗi hiệu năng khi dùng `Objects.equals()` và thay thế `VectorMask.toLong()` bằng SWAR (ngay cả trên x86). Kết quả bất ngờ, tốc độ cải thiện rõ rệt!

Hey all! 👋🏻
I’m looking for some shader-like pipeline/#rendering system/library/framework for 1-bit graphics with 2x #framebuffer (double-buffered — actual & previous) with #blitting on #SIMD and #SWAR? CPU-only, mostly targeting ARM32/64/Thumb1.
I understand that it’s rare and mostly impossible to exist, so I just need some source-based guidance/hints of oldschool/demoscene- tricks and algorithms which I don’t know yet (I know a lot already, I’m 40)) and of course i can port.
