   eBPF does to Linux what JavaScript does to HTML. http://www.brendangregg.com/blog/2019-01-01/learn-ebpf-tracing.html

10. 10.

    eBPF is so good at tracing/networking

11. 11.

    Such as seccomp, perf, tc, XDP

12. 12.

    We use Linux to do cloud-native stuff, so eBPF is

    effective
13. 13.

    But eBPF byte codes are hard to write

14. 14.

    BCC can create eBPF program in combination of a little

    C and Python/Lua
15. 15.

    bpftrace(8) is a new dtrace
 having a flavor of eBPF

16. 16.

    IO Visor is (also)
 a Linux Foundation Project
