Geekfest: Node.js Under Water

Geekfest is a weekly event held by Groupon's engineering team. Every Tuesday at lunchtime, the company invites members of the tech community to present topics that are interesting to a technical audience. Hightower was asked to present OpenROV at Geekfest on Tuesday, October 21, 2014. This is a longer version of the talk presented at the NYC Node.js Meetup Group.
