🚀 Would you like to improve the latency of your Go apps? In the video below I'll walk you through 5 optimizations using @datadoghq's new profiling timeline feature. Finding and fixing those problems would have been really hard with other tools ✨. https://t.co/RxO7snGbRe

The talk Florian Lehner 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!

Asking the right question. Good code review tools are more important than ever. My main wish: interdiff workflow like Gerrit.

Hot take Sunday: `jj` *is* that good. I've switched sway to Cosmic, neovim to helix (experimenting with Zed), zsh to nushell; I've tried "all remote work" on a beefy server, after a souped up "gaming" laptop; And yet, `jj` remains the single biggest life changer.

I love Zstd. It is my default goto for anything compression related: it has a sweet spot between availability (it’s now standardized!! RFC8478), complexity, performance and compression ratio. My favorite thing about it are the skippable frames. Just a killer feature. It’s not

My usual workflow is firing off the same query in ChatGPT 5 and Gemini 2.5 Pro these days. Typically they align, but one answer is better than the other. But it turns out no amount of AI can solve the "too many chefs in the kitchen" problem 😂.

Having fun using pikchr to generate diagrams for my critical path analysis talk at GopherCon US.

🧭 CPU profiling isn’t telling you the whole story. Let’s fix that! Join @felixge as he introduces a novel approach to analyzing Go request latency using critical path analysis—one that goes beyond traditional CPU profiling, logs, or traces. You’ll learn how to root out hidden

The unsexy truth for the build in public hypeboys is that its not a lot of work or time to get a sexy demo, but it is a lot of work and time to translate that into meaningful value (a lot of that being non-technical). And I see too many people repeatedly celebrating the demo.

Just updated the proposal to use a struct based API that reuses the existing EventType structs in the trace package. Feedback welcome! 🙇🏻‍♂️

Wrote up a small proposal to make it easier to test code that is processing #golang execution traces using the x/exp/trace package.

Very few things are more cursed than the way VS Code extensions determine which local development tools to use. This is especially true when using remote hosts via ssh.

Just released async-profiler 4.1 is compatible with JDK 25, adds OpenTelemetry Profiles Data format, improves Native Memory profiling and includes numerous other enhancements:
