Why Everyone Should Care About eBPF
summary
eBPF lets programs attach to kernel and user events to collect and act on live data without changing kernel code: demos use bpftrace one-liners to show syscall counts, command histories, new processes and active TCP connections; a BCC + Python example attaches to the clone syscall and prints a message on each fork. Tooling includes BPF Compiler Collection and verifier + JIT, state is shared via maps, and projects like cilium, Katran/Unimog, Pixie and Falco already use it for faster CNI, observability and security.
