AI Sonnet Dominates, Psychedelics Revised

AVX2 code runs significantly slower than SSE2-4.x code when emulated on Windows 11 ARM, according to a recent analysis. The findings, which directly contradict initial expectations, suggest developers should avoid compiling applications for AVX2 if performance is a priority on Windows ARM devices.

The unexpected performance disparity was revealed in a Hacker News post, which detailed the results of math benchmarks conducted on ARM emulation. The study found that AVX2 code executed at a mere 23% of the speed of equivalent code optimized for SSE2-SSE4.x. The author of the post, who had initially anticipated AVX2's wider operations would compensate for emulation overhead, concluded that compiling for AVX2 on Windows ARM was not advisable if performance was a key concern.

Beyond the performance implications of AVX2 on Windows ARM, other tech developments were also making headlines. GameSir was reportedly developing a Windows emulation tool for macOS, as reported by multiple sources on Hacker News. This tool aims to allow Mac users to play Windows games, potentially boosting controller sales.

Simultaneously, the U.S. Air Force was in the process of repainting Air Force One with a new color scheme. The project includes a donated Qatari 747-8i, and the new design is based on President Trump's preference, according to one source.

Additionally, discussions surrounding terminal color palettes were also circulating. The limitations of base16 themes in terminals were highlighted, with a proposed solution to generate a 256-color palette from existing base16 colors to enhance color range and improve usability. This approach aims to overcome the limitations of current themes without adding complexity.
