Last week the CircleCI Team was excited to sponsor the Tech Crunch Disrupt hackathon. We met a lot of awesome developers and it was great to be able to talk with them about testing, continuous integration, and continuous delivery. There were a lot of teams who tried out Circle for the first time, and a handful of folks who even used Circle in their hackathon entries.

Being Circle advocates, we would love to see people using CI and CD at every possible opportunity, but we acknowledge that, since the goal of a hackathon is to make something amazing in a very short amount of time, it may not be the best place to be writing tests. With this in mind, we decided to give out a prize based on the coolest hack rather than the person with the best use of CircleCI.

There were a ton of interesting submissions and it was great to see both new developers who were at their first hackathon and more experienced developers coming up with cool ideas. The winner of our prize, a $1000 Apple gift card, was Harvest.


The team at Harvest made something truly useful in a very short period of time. They created a crop stress detector attached to a weather balloon that monitors the health of a field of crops and lets the farmer know which sections need to be watered. By combining an infrared camera and analysis tools written in python, they created a platform for tracking trends so that farmers can get a better understanding of the health of their crops. The practical implications of Harvest’s submission are huge: with their crop stress detector, farmers can water only the parts of their fields that are in need which reduces water waste and crop loss.

We also wanted to give an honorable mention to git2docker. git2docker takes advantage of CirlceCI’s continuous deployment functionality to create an automated pipeline from git through testing to a Docker Registry. This makes it easy to tag and release docker images and provides a mechanism for rolling back to previous versions.

Thanks to all of the hackers that participated in the Tech Crunch Disrupt hackathon, and congrats again to Ian, Michael, and Judy on the Harvest team. We hope to see you again at the next event.
