When thinking about how to deliver kernel events from eBPF to user space, a lot of people turn to perf buffers or ring buffers. Maybe instead it is time we rethink what we are actually trying to do with that data instead of just trying to move it faster?

Welcome toΒ the Eternal September of open source.Β Here'sΒ what we plan to do for maintainers. As contribution friction drops, maintainers are adapting with new trust signals, triage approaches, and community-led solutions.

"The cost to create has dropped but the cost to review has not."

This is the largest challenge facing open source
