Thrilled to share that I’ve joined @datadoghq.com as a Staff Software Engineer on the Language Platform team for @golang.org 🐹

I’m excited to continue my journey in observability and performance engineering, focusing on building tools that make developers’ lives easier.

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! 🗽

The -toolexec flag hides a super-power in the Go toolchain: it lets you turn every go build into a programmable pipeline. In this session we’ll reveal how a simple wrapper command can inject custom…

You should! This is the way!
Best of both worlds. Use #omarchy with #cachyos repositories!
I usually setup different machines several times a year and I like the out of the box experience like omarchy and cachyos.
It’s not just arch with hyperland though. I liked the ground up DX-based design. It’s easy to extend. I like the direction that take with TUI and webapps. If you have running systems and configuration that you tend like a zen garden, just stick with it.
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 🚀🐧
