haha we got xdp, tcx, BPF_MAP_TYPE_ARENA you name it ;)

check the docs.

r3tr0··on Nobody Is Listening on Port 8125
the choice of javascript was very intentional.

it has some really nice properties for dynamically instrumenting the OS.

and provides lightweight isolation for agents to control probes and do deep packet analysis.

founder here. we are not a bun/node/deno library.

we embed V8 directly and just point it at bpf

r3tr0··on Show HN: Sigwire – a live TUI switchboard for every signal on your Linux box
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.

r3tr0··on Writing a performant autograd on tenstorrent wormhole p1
This is an excellent post to close out 2025!

Great job and cheers to you in the new year!

r3tr0··on WebTransport is almost here to allow UDP-like exchange in the browser
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)

r3tr0··on OpenTelemetry: Escape Hatch from the Observability Cartel
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.

r3tr0··on An eBPF loophole: Using XDP for egress traffic
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.

r3tr0··on Use DuckDB-WASM to query TB of data in browser
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.
