This version of the future isn't appealing to me.

Just a small PSA, don't give your significant other ideas 20 minutes before going to see a comedy show. The Internet is forever @jbrandhorst.com 😘😂🦵🏻 youtube.com/shorts/_MHAS...

Any president that starts a war must be on the frontline to fight in it.

I'll be at #FOSDEM next week! Haven't been since 2014, which feels like a lifetime ago. If we have met or collaborated in the past, or you'd like to say hi, my DMs are open :) #golang #cuelang

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...

The talk @florianl.bsky.social and I submitted has been accepted at KubeCon 2026 in Amsterdam. 🎉 Small wrinkle: The talk says that the profiling signal is in alpha … which is not true yet. Fear driven development will continue until reality and talk description are aligned!

Can We Know Whether a Profiler is Accurate? Spoiler: yes we can! But it took us figuring out a way to work around the fundamental observer effect. stefan-marr.de/2025/10/can-... If you're at SPLASH, don't miss our talk at VMIL today and at OOPSLA on Saturday!

I'm excited to see that github.com/florianl/go-tc reached 500 stars on GitHub! It all began as a way for me to explore loading an eBPF program in pure Go via the traffic control API of the Linux kernel, and it's awesome to see so many people finding it useful. Thanks everyone!

Whoever did #golang "modernize" - thank you! pkg.go.dev/golang.org/x...

Is anybody here able to put me in touch with somebody at Apple who could help with fixing setitimer(2) on macOS or figure out another approach to CPU profiling for Go and other user space programs? github.com/golang/go/is...

New blog post: I am a Rust compiler engineer looking for a new job nnethercote.github.io/2025/07/18/l...

Howdy all. I'm unfortunately not going to be with my employer for much longer due to team relocation. If anyone has any info on roles that would allow me to continue my Rust compiler work (in New York City), they'd be greatly appreciated.

I'll be speaking at GopherCon UK in London this August! Comment below or drop me a message if you'd like to chat about #cuelang or #golang :) Odd that they're not posting on Bluesky though - such a missed opportunity.

I’m at #gopherconEU this week. Let’s chat if you’re here as well! #golang

I have a Thinkpad X1 Carbon 13th Gen Aura -- with an Intel ARC GPU that I'd like to use to compute. I also am using Debian. Now, Intel seems to only publish their drivers for Ubuntu - is there a way to get their hardware to run on Debian? Also, why are all GPU vendors so bad with their drivers?

At least for #golang, avoid using deps.dev for now. It seems to be reporting security advisories based on outdated information, and the project seems unmaintained, as I reported this two weeks ago but got nothing at all.

cut my heap into pieces, this is my crash report: allocation, no alignment don't give a fuck if it faults on assignment this is fatal abort()

Gemini, draw me a diagram of standard TCP headers

If you are at #Kubecon, focused on #observability and interessted in other use cases for #eBPF than metrics and traces, ping me :)

Do not allow Amthor to abolish the German Freedom of Information law! fragdenstaat.de/artikel/exkl...

I don't like using tools when I don't understand how they work.

It's not a matter of it can't happen here, or it could happen here, we're at it's happening here.

I'll be speaking about "The State of OpenTelemetry Profiling" with Damien Mathieu at KubeCon EU's Observability Day on April 1st in London. I'd love to meet as many people as I can while I'm there. Ping me if you're in town! I'll be around from Monday evening until Wednesday evening.

Most of what we call "tech" is about getting the right information into a database and trying to prevent the wrong person from reading or updating it.

Estonia has a mandatory high school course called "Media and Manipulation," where students analyse persuasion techniques, fact-check claims, and recognise propaganda.

I can’t believe it, I finally got my O1A visa!! It also means I can finally accept training requests again and deliver onsite trainings in the US. First stop: @re-verse.io. Hope to see some of you at the conference today!

With Yandex also open-sourcing a multi-runtime eBPF profiler, I am very proud that we were directionally *extremely* right with optimyze/prodfiler. What we built in 2021 is the sort of technology that will run everywhere by 2030.

The #golang encoding/json/v2 proposal is live! Huge props to Joe Tsai for the hundreds of hours he poured into this project. github.com/golang/go/is...

Landed experimental GPU occlusion culling in @bevyengine.org. This is the modern 2-phase occlusion culling system. It's fully dynamic, runs entirely on GPU, and requires no baking and no artist-defined occlusion volumes.

🗳️ Votes are open for #CNCF governing board Silver member reps, and I’d love to continue representing this group ⚖️ We need to balance the needs of vendors, maintainers, projects, community, and end users. Cloud Native is not a zero-sum game, there is room for growth and success for all!

💡 Performance-optimisation bounties! "Send us a changeset that demonstrably improves the performance of this area of our OSS project by n% and we'll reward you with $m." I wish there were such a thing... #bugbounty

What's the point of being rich if you can't afford to do the right thing.

New continuous profiling play which promises GPU profiling and better data analysis: www.zymtrace.com/article/intr... (not mine, but I am investor & advisor)

Vor drei Wochen gab's in Mainz eine besondere Vorlesung. In 90 Minuten ging es um die Physik & Chemie des Klimas; und noch um weit mehr. Ein Video davon ging diese Woche ziemlich rum. Hier dessen wichtigste Inhalte in 9 Minuten. Im Grunde reicht ein Satz: Klimaschutz ist Emissionsreduktion pro Zeit!

Sigh. I really wish we all agreed vulnerabilities in unused portions of dependencies are not worth wasting developer time on. Instead, here's a LOW finding for a vulnerability in x/text that doesn't affect x/crypto. [ from https://github.com/ConsenSys/gnark-crypto/blob/master/audit_oct2022.pdf ]
