Go-Highway – Portable SIMD for Go
Go 1.26 adds native SIMD via GOEXPERIMENT=simd. This library provides a portability layer so the same code runs on AVX2, AVX-512, or falls back to scalar. Inspired by Google's Highway C++ library. Includes vectorized math (exp, log, sin, tanh, sigmoid, erf) since those come up a lot in ML/scientific code and the stdlib doesn't have SIMD versions. algo.SigmoidTransform(input, output) Requires go1.26rc1. Feedback welcome.
In plain words
Go-Highway is a portability layer for Go 1.26's native SIMD support that allows the same code to run across AVX2, AVX-512, or fall back to scalar operations. Built for developers working with machine learning and scientific computing, it includes vectorized implementations of common mathematical functions like exponential, logarithm, sine, tanh, sigmoid, and error function that are absent from the standard library. The library is inspired by Google's Highway C++ library and requires Go 1.26rc1 or later.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
