Hey, I'm the founder of yeet.

This tool was built on top of our engine: yeetd.

We put a lot of work into abstracting BPF into a JavaScript framework to give builders, human or agentic, the ability to use complex kernel primitives with a familiar programming model to build production grade, scalable infrastructure tools.

Our hope is that everyone here will soon be able to build their own tools on-demand, versus buying them.

We separate a lot of the data layer code from the presentation-level code, to make them re-usable and keep the test surface on the actual data's accuracy manageable across all the random edge cases that arise across CPU architectures, kernel versions, and environments like AWS ECS network namespace voo-doo.

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.

we got a couple blog posts

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.

Absolutely love DuckDB. We use it a ton in our product.

I love duck db. We use it a ton for indexing and organizing system / kernel level metrics exported by eBPF.

i will do another one on just the ABA problem and how many different ways it can put your program in the hospital.

i had help GPT help with some grammar, editing, and shortening.

The core ideas, jokes, code, and analogies are 100% mine.

Human chaos. Machine polish.

totally valid.

that benchmarking is something i should have added more alternatives to.

hope you enjoy this article on lock free programming in rust.

I used humor and analogies in the article not just to be entertaining, but to make difficult concepts like memory ordering and atomics more approachable and memorable.

We spend a lot of time on getting these measurement w eBPF
