Every engineering team faces challenges at scale - but what do those look like inside Microsoft? 🌍 @gdams.bsky.social will pull back the curtain on how Microsoft uses Go at global scale and the lessons learned along the way. Grab your ticket and catch this session live! 🎟️ gophercon.com #golang

In 2020, OpenSSL had a vuln related to the signature_algorithms_cert ext. openssl-library.org/news/secadv/... Palo Alto apparently "solved" this in their IPS by blocking connections with "unknown" algs in sigalg_cert. Six years later, we can't add ML-DSA to sigalg_cert in Go. sigalg_cert is dead.

🔥 Replaced the fixed Windows callback table in the #golang runtime with a growable design. No limits, smaller binaries, and ~6,000 lines of auto‑generated assembly gone. go.dev/cl/788700

Sometimes the #golang toolchain is slower on Windows not for the usual reasons, but simply because it’s largely shaped by Unix-first assumptions. Case in point: I just sent a change that speeds up some warm‑cache build commands on Windows by ~40%… by modifying 4 lines of code: go.dev/cl/787340

Just deleted 300+ lines of hardcore C from the #golang runtime’s cgo package. I was halfway through porting them to pure Go… then realized they are not needed anymore 😄 go.dev/cl/756800

Lightning Talk: Go-ing Native: Supercharging Windows Support In Go - Quim Muntal | GopherCon EU 2025

I don't think they post here, but excited to be talking about what the Go Security team does, and why (hopefully) you don't hear much about us, at GopherCon UK in August.

I'll be attending #gopherconEU this week, where I'll give a lightning talk! Ping me if you will be there and want to chat about Windows (or about anything else)

Happy to say that I'll be speaking at @gophercon.com 2025 about TypeScript's port to Go! There's a lot of interesting stuff to talk about, from the effort's inception, the actual process of porting, and all of the Go stuff we learned along the way (gotchas, perf). www.gophercon.com/agenda/sessi...

Found this tonight and it's a really solid read on the Go runtime. Definitely a long post but it's got a lot of useful info in it. Learned a lot about things that I haven't really dug into before from it. nghiant3223.github.io/2025/04/15/g...

It's been almost 1 year without submitting a Go linker change. My head is hurting hard, but managed to put Darwin's GOT (Global Offset Table) symbols into the read-only __DATA_CONST section: go-review.googlesource.com/c/go/+/644055

🎊 Go 1.24 Release Candidate 1 is released! 🏃‍♀️ Run it in dev! Run it in prod! File bugs! go.dev/issue/new 🔈 Announcement: groups.google.com/g/golang-ann... 📦 Download: go.dev/dl/#go1.24rc1

Here are the slides for my talk at London Gophers about what's coming in #golang 1.24! With a special thanks to @bboreham.bsky.social for spotting that I forgot swiss maps 🙈

Proposed moving x/crypto/hkdf to the standard library one year ago: github.com/golang/go/is... 📜 #golang 1.24 will ship with a new package: crypto/hkdf 🥳 Thanks @filippo.abyssdomain.expert and Daniel McCarney for driving the API design and implementing it 👏

Three improvements I've made to os/user.Current for #golang 1.24 (Windows-only): * no longer takes 1-120s when using Active Directory, it's now always in the order of ms * can be used on Windows Nano Server * can be used on impersonated threads
