A mathematical optimization guide explaining how to avoid trigonometric functions in 3D graphics by leveraging dot and cross products directly, using rotation alignment as a concrete example to demonstrate more efficient and numerically stable approaches.
Meta details its FFmpeg optimization efforts at scale, including the upstreaming of threaded multi-lane encoding (FFmpeg 6.0+) and real-time quality metrics computation (FFmpeg 7.0+), enabling deprecation of their internal FFmpeg fork while processing billions of daily transcoding operations.
Benchmark analysis of C++26 reflection compile-time overhead on GCC 16, showing that including <meta> adds ~155ms overhead but the reflection logic itself scales reasonably (~1-2ms per type). Demonstrates that Standard Library headers are the primary bottleneck and precompiled headers are essential for practical compile-time performance in reflection-heavy code.
