I told you BSD Packet Filtering was cool. How cool? So cool that Julia Evans thinks it’s cool. She wrote up some notes on a talk regarding the original BPF paper. When she gets amped about something everybody gets an enthusiastic and accessible explanation.
But BPF has been around for a long time! Now we live in the EXCITING FUTURE which is eBPF. I’d heard about eBPF a bunch before but I felt like this helped me put the pieces together a little better. (i wrote this XDP & eBPF post back in April when I was at netdev)
There’s an easy peasy list of places in Linux where you can hang an eBPF program, plus her post is chock full of links to relevant material.
Brush with greatness. I used to be a barista for Nefeli Caffè on the north side of the Berkeley campus, around the corner from Soda Hall. I worked the closing night shift a lot. Steve McCanne was a regular. No small talk. Really hot, double cappuccino and see ya’.
