What does it take to build a language that lasts? ∞ Join Austin for the Opening Keynote as they explore how Go is evolving for the decades ahead while staying true to what made it successful. See how language evolution, AI, and an open governance model are shaping Go's future. 🛸 🎟️ gophercon.com

excited to talk about the (mostly) boring vulns we have, with a slight digression about how LLMs have completely turned the way vulns are found upside down 🙃

TypeScript is now officially written in Go.

🎊 Go 1.27 Release Candidate 2 is released! 🔐 Security: Includes 2 security fixes to the standard library. 🏃‍♀️ 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/#go1.27rc2 #golang

Election Day is a good day to remind you that you can now request a mail ballot for the general election (or all elections this calendar year, including special elections). No need to wait in line at the polls next time! You can request it online - it takes 30 seconds! requestballot.vote.nyc

Keep it that way.

This is a fun one: I just sent go.dev/cl/790740, which elides method wrappers for embedded types at offset zero, common for mixins/inherited data types. Doing this removes 60 _thousand_ method wrappers from tsgo's AST package, dropping the compilation of our main exe from 49s to 28s on my machine.

New rule dropped: anything above 11239 isn't the real Brooklyn.

PSA: Green Tea GC in go1.26 is incredible 🚀 This is what we saw for two big Go services. We'll try to gather more data and share it soon.

My talk was accepted to GopherCon 2026 in Seattle! I'm back with more TypeScript+Go goodness, this time with another year's worth of experience under our belt. I had a blast at last year's conference, so here's to yet another one! www.gophercon.com/agenda/speak...

A bit over two years after starting to work on it... Go is officially FIPS 140-3 certified 💥 csrc.nist.gov/projects/cry... I am pretty confident Go is now one of the most—if not the most—seamless and complete FIPS 140-3 compliance solutions... with a single env var, out of the box.

csrc.nist.gov/projects/cry... CMVP has (finally!) Validated the Go Crytogrpahy Module for FIPS 140-3. Congrats and Thank you to @geomys.org and @filippo.abyssdomain.expert

@philpearl.bsky.social looked at #golang Swiss tables performance ⭐️ philpearl.github.io/post/swissing_a_table/

Here's an example. Average rent in LA for a 1 BR is $2500. A woman that lives in LA and earns an hourly wage, knows that if she can't work for a month, she needs to come up with $2500 or she will be homeless. After bills, she has only $200 left over. She saves almost all of it, and doesn't eat out.

Additionally, I want to speak directly to Iranian New Yorkers: you are part of the fabric of this city — you are our neighbors, small business owners, students, artists, workers, and community leaders. You will be safe here.

“Allocating on the Stack” by Keith Randall — https://go.dev/blog/allocation-optimizations #golang

🚀 "spec: generic methods for Go" has been accepted! You will soon (1.27?) be able to declare (on concrete types only) methods that introduce type parameters, i.e. type parameters other than the ones (if any) that come from the method's receiver. github.com/golang/go/is... #golang

My phone is now hot but the best part is I’m not sure if that is from the CPU emulator or from GitHub trying to render the 14k source file when I went to see how this works.

Dependabot security alerts have terrible signal-to-noise ratio, especially for Go vulns. That hurts security! Just turn it off and set up a pair of scheduled GitHub Actions, one running govulncheck and the other running CI with the latest version of your deps. Less work, less risk, better results!

Go 1.26 is out, and the announcement says: "Over the next few weeks, follow-up blog posts will cover some of the topics in more detail. Check back later." So you can wait a few weeks OR you can read my interactive Go 1.26 tour right away: antonz.org/go-1-26

Some pretty awesome improvements in 1.26 for compiling/testing typescript-go. With a clean build/test cache, running the full test suite used to take 3m45s, but now takes just 2m10s.

My GopherCon talk was just posted!

PSA: go.sum is not a lockfile. You never need to look at go.sum. go.mod has everything you need.

Go 1.26 is coming soon, and the official release notes are pretty dry. So I prepared an interactive version with lots of examples. Read on and see! antonz.org/go-1-26

The folks behind GopherCon 2025 have kindly shared video recordings of our talks; here's mine on modernizer tools for Go. Special thanks to the amazing Stacy Potenza for turning my rapid limey nerd mumbling into comprehensible closed captions. www.youtube.com/watch?v=_VeP...

My colleague Sanjay Ghemawat & I have done a fair bit of performance tuning of various pieces of code. We wrote an internal Performance Hints document ~2 years ago as a way of identifying some general principles & we've recently published a version of it externally. Doc: abseil.io/fast/hints.h...

Gist of Go: Concurrency is out! Learn Go concurrency from the ground up with 50 auto-tested exercises and tons of interactive examples. It's a full course + book in one. antonz.org/go-concurrency

"why i think #jj-vcs is worth your time" schpet.com/note/why-i-t...

The new chapter of my Go Concurrency book covers the scheduler and its implementation details. It's not meant to be a deep dive. But it's short, easy to understand, and will teach you more about goroutine scheduling than many other developers know. antonz.org/go-concurren...

I documented the steps and missteps I took with jj (jujutsu) getting a repo set up from scratch, initial commits made, and pushed to github. This is the intro workflow I needed, but couldn't find. www.visualmode.dev/from-zero-to...

Accepted! Go 1.26 will introduce per-state goroutine metrics: running, waiting, in syscalls, etc. Developers can use them to catch problems early without needing full traces. antonz.org/accepted/gor...

BREAKING: This is huge news, the EU's equivalent of the 🇺🇸Supreme Court's 2015 Obergefell v. Hodges ruling. 🇪🇺Court of Justice just ruled all 🇪🇺countries must recognise same-sex marriages granted in other member states. This effectively legalises gay marriage across 🇪🇺
