Hackers On Planet Earth (HOPE) is a biennial hacker conference in New York City, organized by many people involved with 2600: The Hacker Quarterly.. I have been attending and volunteering since HOPE2K in 2000, and have presented panels since The Fifth HOPE in 2004. Beginning with The Last HOPE in 2008, I joined the HOPE's core staff. I also contribute art and design work.
More information about HOPEs past, present, and future can be found at the event's Wikipedia entry and the official HOPE site.
