Frederic Branczyk on Continuous Profiling Leveraging eBPF

Wes Reisz and Frederic Branczyk discuss the origin story of Polar Signals, eBPF (the enabling technology used by Polar Signals), Parca (the open-source system they built to collect continuous profiling data), and more, including things like FrostDB and why profiling data complements what we already have with our current observability stacks.

Liz Rice on Programming the Linux Kernel with eBPF, Cilium and Service Meshes

Charles Humble and Liz Rice discuss eBPF, a way of making the Linux kernel programmable. They talk about why it exists, how it works under the hood, and what you can and can’t do with it. They also talk about Cilium, an open source library for observing network connectivity between container workloads, and the new Cilium-based service mesh currently in beta.

Louise Poubel on the Robot Operating System

Louise Poubel is an engineer working with Open Robotics. Today on the podcast, she talks about what it takes to develop software that moves in physical space, including the Sense, Think, Act Cycle, the developer experience, and architecture of ROS.

Bryan Cantrill on Rust and Why He Feels It’s The Biggest Change in Systems Development in His Career

Today on the podcast, Bryan Cantrill discusses with Wes Reisz a bit about the origins of DTrace and then spends the rest of the time discussing why he feels Rust is the “biggest development in systems development in his career.”

Justin Cormack on Decomposing the Modern Operating System

Justin Cormack discusses how the modern operating system is being decomposed with toolkits and libraries such as LinuxKit, eBPF, XDP, and what the kernel space service mesh Cilium is doing. Wes Reisz and Justin Cormack also discuss how Cilium differs from service meshes like an Istio, Linkerd2 (previously Conduit), or Envoy.
