This is the story of the most unbelievable demo I've been given in world of open source. He was kind enough to give me a quick demo anyway. He gave me a path to start looking under, and after a bit of searching I found the directory with all the tools he had been demoing. You can't make this stuff up. I printed socketsnoop.d.

For my AWS re:Invent talk on BPF Performance Analysis at Netflix, I began with a demo of "BPF superpowers" (aka eBPF). The video is on [youtube] and the demo starts at [0:50] (the sildes are on [slideshare]): I'm demonstrating a tool I developed to turn my laptop's wifi signal strength into audio. The source is: #!/usr/local/bin/bpftrace

There's an arms race to add eBPF (BPF) to commercial observability products, and in this post I'll describe how to quickly do that. People like to show me their BPF observability products after they have prototyped or built them, but I often wish I had given them advice before they started. You might not even like BPF.

It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., In case you are interested, at the same conference I also gave a talk on [BPF Internals].
