With #FlightRecorder #Go introduced a powerful tool. As I'm involved in the #OTel Profiles signal, I have created an OTel receiver that transforms Go's FlightRecorder format into the OTel Profiles signal. Now you can analyze Go diagnostics in your own favorite backend/UI! github.com/florianl/fli...

Related #golang PSA: Gophers often mistakenly put a -u in 'go get -u foo', when they would have been better off with just 'go get foo'. 'go get foo' says to upgrade foo itself. It's shorthand for 'go get foo@upgrade' 'go get -u foo' says to *also* upgrade all the direct and indirect deps of foo.

FIRE subreddits are wild. Everyone’s 29, retired, owns 3 rentals, and “just got lucky with some BS hype .” Meanwhile I’m emotionally attached to my budgeting app.

Authenticated CLIs + skills are more secure, faster, and cheaper than MCPs for external services in Claude Code. But sure, let’s add more layers of complexity. That always works.

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

8 years in Germany. Finally converted my driver's license. Time-to-completion is only slightly worse than continental drift. Proudly nominating myself for Procrastinator of the Decade.

I just came across two surprisingly handy macOS utilities: github.com/tw93/Mole and github.com/productdevbo...

Because one talk over a weekend apparently wasn’t enough bad life choices: Also on Sunday, 12:30–13:10 in H.1301 (Software Performance devroom) I’ll be speaking with Augusto de Oliveira: “How to Measure Software Performance Reliably”

I’m heading to FOSDEM 2026 🧪 On Sunday, 13:30–14:00 in UB5.132 (Go devroom) I’ll be co-presenting with Hannah Kim: “How to Instrument Go Without Changing a Single Line of Code” Basically: all the ways to get observability without touching your beloved git blame.

This past week I used my R&D week at @datadoghq.com to build a WASM transpiler that generates Go (ARM64) assembly code. It's not publicly available - I want to rebuild it from scratch - but I can tell you that it works!

I'm looking for a PR review tool dedicated and native to macOS. I tried tools embedded to VS Code, but I didn't like the experience. I want good UX and standalone app (so that I can track how much time I spent reviewing code). Any suggestions?

Technically “fuck around and find out” is the scientific method

@deadprogram.com I would love your opinions on this 😊

A bit more context: I have libraries written in other native languages that I want to expose from a Go package/module. Today, there are basically two ways to do this: 1. CGO and link against those libraries. 2. purego (e.g. github.com/ebitengine/p...) and dynamically load them.

Does anyone know someone attempted to transpile WASM to Go ASM? Or similar?

No monitoring and observability room? 🤔 cc @richih.bsky.social

If you have an interest in understanding garbage collection better, or in how Go's new GC works under-the-hood, I highly recommend reading @michael.express's thorough guide through Go's current and Green Tea GC.

NYC friends — I’ll be in town next week! 🗽 If you’re around and up for a coffee, let’s make it happen ☕️ Also, it’s been a minute, and taking cool spot recommendations!

Breaking my #PromCon streak since 2018 😭 Work travel, family, and a bit of health issues this year. Feels weird to miss it 💔

Berlin friends 🐻 if you’re serious about #observability and #OpenTelemetry, don’t miss this one. The OpenTelemetry Collector Workshop (Oct 29–30) is two days of deep dives, labs, and production-ready patterns from folks who build and run OTel at scale. 👉 telemetrydrops.com/events/2025/...

Got feedback from someone I deeply respect. It was sharp, honest, and right. I could’ve done better, and I will. Pressure and pace aren’t excuses. Just reminders to be more intentional. Raising my own bar again.

One of my favorite hobbies is adding new features to my personal blog that I never actually write posts on. It’s right up there with buying books I don’t read.

I’ll be in Paris next week 🇫🇷 Ping me if you want to grab a drink and chat!

I recently spoke at GopherCon UK 2025 about the hidden power of #Go’s `-toolexec` flag. How it can turn every `go build` into a programmable pipeline for things like error-handling enforcement and observability hooks. Here’s the recording:

Best of both worlds. Use #omarchy with #cachyos repositories!

Friday night. Some people party. Some people drink. Me? Installing yet another Linux distro for “fun.” Let’s see what the #Omarchy bandwagon is all about 🚀🐧

Second-to-last slot at #GopherConUK25. ADHD ensured I prepped at the *optimal* time: right before going on stage. Didn’t enjoy the conference much — probably just tired. Glad I did it though. The talk… might’ve actually been good.

What CAME in #golang 1.25! #GopherConUK by @mvdan.cc

It’s GopherCon time again #golang

Speaking at www.gophercon.co.uk this year! If you’re thinking of coming but cost is a blocker, I’ve got some promo codes I can share. Just DM me – happy to help!

Check out this new blog post outlining how profiling is becoming the fourth pillar of observability 🚀. www.datadoghq.com/blog/continu...

This 👇 “Reason 5: OTel SDKs are complex and can be very slow” It is really challenging to maintain this level of performance and simplicity without breaking any of the downstream systems like Kubernetes and Prometheus. Contributions are always welcome: github.com/prometheus/c...

Fantastic new blog post from my colleague Nayef. If you're into Go internals, check it out! www.datadoghq.com/blog/enginee...

👇 This is what we have been working on. It is a must-watch if you would rather not instrument your #go programs yet want to have all the benefits of observability! And Hannah is awesome! Brace yourself for the first-class memes!

This is very good. www.404media.co/the-medias-p...

Things can only happen in Berlin: I got to have doner kebabs for lunch with my gopher heroes! @felixge.de @dave.cheney.net @deadprogram.com @goinggo.net @gopherconeu.bsky.social #gopherconeu

It’s #GopherConEU time — and the best part is that it’s in my hometown Berlin, so I get to from my own bed!

This week I'm playing with checklocks from gVisor — a static analyzer for Go that detects lock ordering issues at compile time. Works like magic. 🔐✨ pkg.go.dev/gvisor.dev/g...

That time of year came! FOMO for #KubeCon kicked in 😭

We need a Go linter that flags the use of "defer" in our test cases. Instead, it should tell us to switch to using

Maybe I can finally learn German this way!!? 🤔 😛

This week was tough, but this made my day ❤️ #opensource

Finally did it—after a decade, Go officially overtook Ruby as my actively* most-coded language! 🥳 Took a long journey from my caffeinated Ruby-monkey days to becoming a dedicated gopher. Progress! *hands-on the keyboard!
