In case anyone else wants to play with Zig on webassembly, here's what you need to do to make it work on a mac today.
You'll need LLVM to output to the WASM target. This has just been added by default in trunk, so if LLVM >7 is available, you might be able to just brew install llvm.
If you have wasm support already you should see:
$ llc --version
This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).
Matrix multiplication is a mathematical operation that defines the product of

Note: a lot of programmers talk about UI without mentionning the user even once, as if it was entirely a programming problem. I wonder what we’re leaving off the table when we do that.
