Cap'n Web is a new open source, JavaScript-native RPC protocol for use in browsers and web servers. It provides the expressive power of Cap'n Proto, but with no schemas and no boilerplate.

eBPF lets you run small, verified programs inside the Linux kernel, enabling fast observability, security, and networking without changing application code. This practical tour explains why eBPF matters now, how programs are compiled, verified, JITed, and attached to events, and how maps and ring buffers move data. You'll leave with simple demos and a clear mental model to start experimenting.

As coding agents mature and developer adoption accelerates, organizations can produce code faster than ever. But with speed and agent-written code comes risk and merge conflicts. To unlock shipping fast – and safely – mitigating these issues is essential. Here's how agent-ready feature flags make this possible.

While working on adding process identification to the network monitoring tool RustNet, I discovered interesting differences in how macOS and Linux tackle a quite common challenge: mapping network packets to processes. Especially tricky seem to be those short-lived processes that traditional polling approaches often miss.
