Apparently you enjoy molesting TCP packets. Would you say this is your favourite activity? Does anything else come close, and if so what?
Yes, I love looking at the details of network protocols on the wire! I do love other things too (Sailing, travel, bushwalking etc), but it's great having a job where I get to do one of my favourite things.
You are a very popular speaker at the Linux conference. How many times have you spoken at the event and why do they keep asking you to return?
