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!

🚀 Datadog is hiring an Engineering Manager to drive our #OpenTelemetry strategy! Lead a high-impact OSS team shaping observability at cloud scale. 🌐 Hybrid NYC or US remote. Interested? Apply / DM ➜ careers.datadoghq.com/detail/6964303 #Hiring #Engineering #OSS #Observability

Thanks to the agent wave, my favorite tools finally expose #MCP APIs. Now my entire workflow automates itself in a uniform structure. Give me APIs for all the things #automation #AI

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!

TIL Cursor has a great security page!

New typescript-go avatar just dropped!

Spent a week coding with Cursor. Here’s what clicked, what didn’t, and why I might just keep using it: 🔗

Just got my @jetkvm.bsky.social from a Kickstarter campaign! Time to tinker.

Looking for a tool that automatically rewrites old error-checking patterns to use errors.Is / errors.As for #golang I know github.com/polyfloyd/go... catches these issues, but I need something that fixes them. Does such a tool exist?

Open-weight models aren’t open-source. They’re just ‘look but don’t touch’ machines. Stop pretending.

This one’s a bit dated, but it’s a great reminder of Go’s design philosophy. Simplicity, readability, and pragmatism over cleverness. Always worth revisiting! #golang 📝 The Tao of Go: 🔗

Managing tool dependencies in #golang is finally a joy! 🎉 Go 1.24 introduces tool directive for go.mod, making it seamless to track and install tools. We’ve come a long way, and I love these small but impactful improvements to the tooling. Great write-up: 🔗

Instrument all the things, in every way—leave no process unobserved!

At @datadoghq.com we are always hiring. We are looking for a new fellow to work on our agent and OpenTelemetry! Ping me if you want to know more. careers.datadoghq.com/detail/65977...

Roc is re-writing from #rustlang to #ziglang gist.github.com/rtfeldman/77...

Just wrapped up #FOSDEM—always a pleasure! If you’re into open-source, this is the conference you can’t miss. Loved catching up with friends and seeing all the amazing projects people are working on. Until next time!

Yet another talk about #eBPF and @opentelemetry.io auto-instrumentation on #FOSDEM by @fstab.bsky.social and Rafael Roquetto It’s crazy to everyone heading to this direction these days!

Great talk on cost of @opentelemetry.io auto-instrumentation at #FOSDEM

🚀🚀 @prometheus.io v3 by @bboreham.bsky.social and Jan Fajerski

Starting the day two of #FOSDEM. I will spend the whole day on #observability and #monitoring devroom. Surprised?! 🤪

Nobody leaves #eBPF room at #FOSDEM so nobody gets in 🥲 Early bird catches the worm.

Swiss Maps from @bboreham.bsky.social #FOSDEM

Let’s start! #Go devroom at #FOSDEM

It’s #FOSDEM o’clock!

Yandex released a new eBPF profiler. If you're into profiling, I highly recommend reading their announcement post. It covers a lot of background knowledge, and also introduces some cool new ideas such as capturing micro coredumps when a process gets killed! medium.com/yandex/yande...

I'll be at #FOSDEM this weekend! 🎉 If you’re attending and want to chat about open-source, observability, or just geek out, I’d love to meet. Let me know! 🚀 fosdem.bsky.social

People keep sharing their magical success stories with Cursor. Meanwhile, mine just spits out pure bullshit (pardon my French). I’m not even doing anything niche—fed it step-by-step clear instructions with examples. Is my Cursor defective, or am I just cursed?

We are starting a new initiative to bring compile-time instrumentation to #OpenTelemetry Go! 🎉 This will enable lightweight, high-performance telemetry without manual instrumentation. 🚀 A promising initiative shaping the future of observability in #golang. https://opentelemetry.io/blog/2025/go-co…

#Golang 1.24 is packed with upgrades: generic type aliases, weak pointers, faster Swiss table maps, and enhanced cleanup functions. Dive into what’s new:

A great mentor or manager can make all the difference when joining a new organization. They’re the bridge between you and the culture, turning what could feel like survival mode into thriving mode—regardless of the size of the group or organization.
