How eBPF Empowers Developers to Observe Inside the Linux Kernel in a Safe and Unintrusive Way

Daniel Finneran explores how eBPF has evolved far beyond its roots in packet filtering into a robust, safe way to extend the Linux kernel. He explains how the eBPF "verifier", the security guardrail, enables implementation of deep observability and networking without the risks of traditional kernel modules or the slow upstreaming process.

A Java Performance Quest: Taming Unsafe Code, Embracing Idiomatic Style & Debugging the Linux Kernel

In this podcast, Jaromir Hamala, a seasoned Java engineer specialising in high-throughput data systems, shares his thoughts on how developers can tackle high-performance software development. He touches on the benefits of modern Java that allow writing idiomatic Java code while remaining "mechanically sympathetic", and also on his experience debugging a Linux kernel bug.

The Future of Service Mesh with Jim Barton

In this podcast, Jim Barton explains some of the fundamentals of modern service meshes, and provides an overview of Istio Ambient Mesh and the benefits it will provide in the future.

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.
