Silicon Valley International Game Developers Association has added a Hackathon event to its HTML5 Developers Conference, which has already received over 700 registrations.

Also announced was a list of speakers who will be making presentations at the event, including David Herman of Mozilla, Jason Hoffman, founder and chief scientist of Joyent, Frank Greco, director of technology of Americas at Kaazing, and representatives from Nokia.

Ben Savage of Sibblingz will be the keynote speaker.

Doug Crockford, author of JavaScript: The Good Parts, Josh Elman, formerly of Facebook and Twitter and several speakers from the Google Chrome team and game engine libraries at Microsoft are also making presentations.

Hack by popular demand

The event itself will take place on September 27 at the Westin Hotel in San Francisco, though the additional Hackathon event will be held at the Eventbrite Headquarters in San Francisco on September 24 and 25.

The Hackathon event will give opportunities for game developers to hack on a variety of application programming interfaces including Sibblingz's Spaceport platform, Eventbrite, Crowdstar, MongoDB, Yahoo, Google, Node.js, and more.

The winning developers at the Hackathon event will be awarded tickets to the HTML5 Developer Conference and will be part of a five minute presentation ceremony on stage.

They will be awarded first, second and third place cash prizes by Sibblingz with Eventbrite, Crowdstar and MongoDB also awarding prizes.

"With the overwhelming interest we've gotten in HTML5DevConf, we thought there was a clear opportunity to reach out to thought leaders in the gaming developer community and host an HTML5 Hackathon," said Ann Burkett, chair of SV IGDA and conference organiser.
