Go Library

In a few hours of work, with the help of modern programming tools, I've successfully implemented ChaCha20 for amd64 AVX2 and AVX512 and arm64 NEON. It's even slightly faster than my ChaCha implementation in Rust while being 10,000 times easier to write and read!

The most recent release of both have a massive uplift in performance that borders on the absurd. Wall clock down ~30% and CPU time down by nearly 4x.

Network-aware SSH router. Detects your active network or VPN and automatically selects the right host, port, identity file, and jump host for each SSH connection — without touching ~/.ssh/config.

For 14 years, starting with Go 1.0, encoding/json shipped with known problems, such as case-insensitive field matching, that were never fixed. This book traces the road to encoding/json/v2, formalized in Go 1.27, through the issues, proposals, Gerrit changes, and standard library source that shaped it.

Let me guide you through the process end-to-end.

Meet packetio, the Go packet I/O library I wish I'd had a years ago. AFXDP, DPDK, mlx5 Direct Verbs, and AFPACKET behind one API.

This August, I accomplished what I wanted for many years: I deleted the last cgo dependency in Debian Code Search! This was made possible by Go’s recently introduced SIMD support, because now we can implement the TurboPFor integer compression format as efficiently — more efficiently, in fact, by using the newer AVX512 instruction set! — as the reference implementation.
