GopherCon, the largest event in the world dedicated to the Go programming language, is being held in Denver, CO this year July 11th-13th. I am speaking about packet capturing in Go using the Gopacket package. The talks will be available on YouTube afterwards.
UPDATE: The videos from GopherCon have been released. Here is a recording of my presentation.
