In July, the BuzzFeed Tech team took a week off of "regular" work to hack on new and exciting projects.
The BuzzFeed Tech Team puts on a Hack Week once a year to help stretch our imaginations, work with people outside or normal teams, and have fun as a Tech organization. This Hack Week, we created 38 different projects from Tech teams all across the globe.
BuzzFeed Tech is made up of ~230 folks, including engineers, product designers, product managers, QA analysts, data scientists, data analysts, product support specialists, and project managers. We maintain and build internal tools as well as consumer facing products like our website and apps!
Here's what we came up with!

1. StickerBomb
2. Virtual Reality Quiz
3. BuzzFeed & Chill
4. In-Frame

Normally, users would have to enter the app to take one of BuzzFeed's many quizzes. Now, simply by adding the BuzzFeed Quiz Widget, users can complete any quiz from their home screen.

We used Apple's new Core ML technology to run a convolutional neural net that gauges the user's emotion (https://gist.github.com/GilLevi/54aee1b8b0397721aa4b) via the iPhone's front-facing camera. We can then leverage this for mood based quizzes and challenges. Our demo app shows the user a funny video while challenging them not to smile for 30 seconds. We use the emotion prediction probability to gauge when the user is starting to smile and give them a warning, and if we ever can't find a face we'll pause the video and timer.
Team: David Mauro, Wolasi Konu, Pete Walters

Using in-video retention data from YouTube, our system identifies the most watched parts of a video and retrieves them as clips. These clips can then be stitched together to make a highlight reel, or shown to creators to inform them about the most appealing parts of their video.
