It's [a hackathon][1] supported by Stack Exchange, Code for America, and New York City.

##Help create tools or applications that will enable New Yorkers to easily access 311 information on a mobile device.##

While Stack Exchange is not “Made in NY” (we’ve been built with code conceived across the globe) our headquarters is located in New York. We love New York. And we want to give back to the city by promoting an initiative that aligns with our goal to make the Internet a better place to find authoritative answers.

**We hope you help by participating in the hackathon**... even if you're not a New Yorker or living in NYC.

**Prizes** are on the line. So is an opportunity to visit Stack Exchange HQ on demo day and present your work to [a panel of judges][2] that includes **Joel Spolsky**. 

Some fine print: Up to 15 semi-finalists (individuals or teams) will be invited to present. Up to 5 finalists may be awarded at the demo event. Prizes are TBA. All participants who are invited to demo day must cover their own travel expenses and provide their own room and board. And while all hackathon participants are eligible to visit Stack HQ on demo day, only US residents 18 and older are eligible to win prizes. This is a city organized event, and well: lawyers. 

A few key dates:

 - Tuesday, **December 10** - [Open information session][3] and Q&A with city
   employees who manage the 311 Content API and NYC Developer Portal
 - Monday, **January 6** - Submission period ends 
 - Friday, **January 10** - Semi-finalists will be notified if they have been selected to present
 - Wednesday, **January 15** - Reinvent 311 Demo Day at Stack Exchange HQ

To participate, sign up **[here][4]**.

Hope to see you at the office!
