The eBPF in-kernel virtual machine is approaching its tenth anniversary as part of Linux; it has grown into a tool with many types of uses in the ecosystem. Alexei Starovoitov, who was the creator of eBPF and did much of the development of it, especially in the early going, gave the opening talk at Linux Security Summit Europe 2023 on the relationship between BPF and security. In it, he related some interesting history, from a somewhat different perspective than what is often described, he said. Among other things, it shows how BPF has been both a security problem and a security solution along the way.

When users encounter slow load times or delays in response from any web application or API, they are more likely to abandon it. Caching plays a crucial role in improving performance and efficiency. Here's how it works.

ABAC vs. ReBAC - A comprehensive guide to the pros, cons, use cases, and implementation of these common authorization models

I enjoy how developing Spectral rules to govern an API slows us down to think about what matters. Really this is the biggest problem I see with people building APIs—-they are just moving too fast, and they refuse to slow down and think too deeply about things. I enjoy the frame rate in which Spectral rules attach themselves to the contracts we are producing for our APIs, and I figured I’d further expand on the opportunity to tell some stories around these machine-readable API policies we are applying, or often times not applying consistently across our API operations.
