If I wanted to create a web browser from the ground up, I would do that in C#. And I would not use graphical libraries such as Xlib or Cairo, none of them has good hardware support. I think the right way is building on top of 3D GPU APIs, l

For production code as opposed to exams of job interviews, it’s usually better to use hardware implementation. All modern CPUs have instructions for that, popcnt on Intel/AMD, vcnt.8 on ARM Neon. Many languages have standard library fu

Why do you think the market inevitably becomes a monopoly? In the last 20 years we had generations when AMD CPUs were better (Athlon XP, Athlon 64, Zen 2, Zen 3) and generations when Intel CPUs were better (Core 2 Duo, Sandy Bridge, Haswell

My guess it’s their deliberate design decision. It could be that most users of the library don’t care about small things. About the template stuff, I think their main performance advantage over traditional BLAS is not even SIMD, it’s lazy e

Using it for years, and mostly happy with that library. The performance is awesome for very long vectors / large matrices. It’s less than ideal for small things when the size is known at compile-time. If one knows SIMD intrinsics, in s

That thing is COM, which is a small subset of C++ ABI. Technically it’s about the same as on Windows, i.e. C ABI with extra first argument for this pointer. Once upon a time I made this library https://github.com/const-me&#x

Apparently, the OP’s issue was ABI incompatibility between VC++ (also used by Windows SDK and everything built on top, including Direct3D 12), and System V (used on Linux, also MinGW on Windows). VC++ documentation says structures are retur

I agree. I recently read the book "American Muckraker" by James O'Keefe. It has quite a few examples of that in modern US. Based on unconfirmed rumors, similar things do happen here in Montenegro as well.
