The week of June 23rd was a good week for gophers in San Francisco. Go was a big part of Google I/O on Wednesday and Thursday, and on Monday Google run a Go SummerFest, a special instance of the GoSF meetup.
I gave a talk at Go SummerFest and then later on another one during I/O. For more information about the events, see this blog post from the Go team.
My talk was recorded but it is not yet online.
