Roman Poya's personal blog at romanpoya.medium.com covers programming and science. Since 2022, 6 different Hacker News readers have linked it 6 times, most often “C++ Expression Templates: Eigen, Blaze, Fastor, Armadillo & XTensor (2020)”. The last post was in 2020, but the archive is still widely read.
Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN readers link Roman Poya's performance benchmark of C++ math libraries (Eigen, Blaze, Fastor, Armadillo, xtensor), covering run-time and compile-time performance, as a comparison source.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
These benchmarks look to be ~8 years old, and don't really agree with benchmarks done by other sources ( https://romanpoya.medium.com/a-look-at-the-performance-of-ex... , https://eigen.tuxfamily.org/index.php?title=Benchmark ) In general I would be skeptical about any benchmark that claims to beat MKL significantly on standard operations
