Koding Inc. has announced its second annual global virtual hackathon, set for December 12-13. Sponsored by IBM, this year’s virtual event is expected to draw more than 100,000 participants worldwide, setting a new Guinness World Record and surpassing last year’s inaugural event, which set the record for the largest-ever virtual hackathon.

IBM’s sponsorship of the event is part of the company’s strategic relationship with Koding, a developer community and cloud-based developer environment that allows users to easily work, collaborate, write and run apps—all within a Web browser. Confirmed hackathon participants will receive an invitation for a free trial of IBM Bluemix, an implementation of IBM’s Open Cloud Architecture based on Cloud Foundry, an open source platform as a service.

Registration is now open, and teams of up to five developers from around the world can sign up for this year’s hackathon at https://koding.com/Hackathon. During the event, participants will have 48 hours to hack their way into $150,000 in cash prizes. This year’s themes include educational games, enterprise productivity and data visualizations.

Koding was inspired to tap the minds of developers all over the world for a second year after an overwhelmingly positive response to last year’s event. Koding’s 2014 hackathon had more than 60,000 participants from a total of 900 total cities, and more than 500 projects were completed and submitted within 48 hours.
