What is DevFest?

DevFest is a week-long learnathon that culminates in an 18-hour hackathon. DevFest focuses on fostering community and helping new developers end the week with a completed project. ADI hosts DevFest every Spring.

Who can participate?

Any student from the Columbia community (SEAS, CC, Barnard, General Studies, or any of the graduate schools) can register and participate in the hackathon. If you are not a member of the Columbia community, you're welcome to come to any of our events during the week, but the hackathon will be closed off to CU students.

Do I need experience?

Students of ALL experience levels are welcome! If you've never programmed before, the Beginner Track is perfect for you. The Beginner Track will teach you how to build your own website, and requires no prior programming experience. If you do have prior experience, sharpen your skillset by working on the Web Development Track, iOS Development Track, or Data Science Track.

What is the DevSpace?

The DevSpace, located in Carleton Commons, is where you can work on any of the 4 DevFest Tracks with the help of TAs and peers. The DevSpace will be open 8 - 11 pm, Monday through Thursday.

What are the DevFest Tracks?

The DevFest Tracks are a collection of self-paced comprehensive online tutorials in a variety of technical subjects. Each track teaches you how to build a fully-functional project from start to finish. We are offering 4 tracks this year: Beginner, Web Development, iOS Development, and Data Science.

Do I have to come to the entire week?

No, but be sure to register and attend as many events as you can. We will have different company sponsors, tech electives, and fun activities every night, so come to as many as you can!

Will there be food?

What would an ADI event be without food? There will be dinner for kickoff (Monday night) and snacks throughout the week. We'll also be serving meals and snacks at the hackathon.

Do I need a team or idea to sign up?

Nope! Just come with a willingness to learn something new :) Don't worry if you don't have a team. We'll have a team-formation event at the beginning of the hackathon.

How big can my hackathon team be?

The maximum team size is 4.
