If any of my friends are at DEF CON this week and I haven't yet run into you, please find me and say hi! I'll be around the Policy track most of the day. Speaking on #DigitalEmblems at 13:30 in Track 3, and interviewing Ng Yeow Boon in the Policy track at 17:00. Tomorrow, Saturday, I'll be giving a talk on the intersection of #InternetEconomics, #InternetMeasurement and international balance of trade in the Policy track at 12:30.
