Ask HN: Are my HPC professors right? Is Python worthless compared to C? (ycombinator.com)
I'm a PhD student implementing a finite element code. It simulates electromagnet waves passing through heterogeneous material. This code has to run in parallel, and run fast. I've been using old C libraries like PETSc to do this, and honestly, I do not enjoy working with C at all. Its esoteric and difficult to understand, and just overall feels like I'm using a tool from the 70s.

Building a compile-time SIMD optimized smoothing filter (scientificcomputing.rs)
I built a Savitzky-Golay filter (fancy name for a dot product with some known constants on a rolling window) and tried to optimize the crap out of it.

Performance of Eigen vs. Blaze vs. Fastor vs. Armadillo vs. XTensor (2020) (medium.com)
It is March 2020. C++20 is almost around the corner and as a scientific C++ programmer I am quite thrilled with the new features that the language is getting.
