This is an excellent post to close out 2025!

Great job and cheers to you in the new year!

I have been counting down the days.

It will help a ton with the low latency streaming we need to do in our eBPF based Linux performance tool. (https://yeet.cx)

OTel's real bottleneck isn't the spec. It's the fact that it requires you to instrument the app itself. That couples your performance to the maturity of the least stable SDK you depend on.

eBPF solves this by reversing the model: instrument the system, not the application. Turn it on / off dynamically, zero redeploys, minimal overhead.

The missing piece is accessibility. Kernel-level observability exists; "normal engineers can use it" and good DX does not.

XDP is awesome.

We use it quite a ton for capturing and dashboarding inbound network traffic over at https://yeet.cx

I am really excited for the future of eBPF especially with tcx now being available in Debian 13. The tc API was very hard to work with.

It's one of the best tricks in the book.

We have been doing it for quite some time in our product to bring real time system observability with eBPF to the browser and have even found other techniques to really max-it-out beyond what you get off the shelf.

That's pretty cool. Any technical blog posts?

we got a couple blog posts
