[racket] RacketCon live video

Hi all,

We are planning to air a RacketCon live stream again this year via
Google Hangouts. Barring any technical difficulties, we'll have the
stream up tomorrow at this link:

The program is here:

Last year there was a cap on stream length, so we may have to switch to
a new stream partway through. We'll send out a new link if we have to do
that.

Cheers,
Asumu
