Day 4 of AAS 223, the final day of the conference, and the famous annual Hack Together Day! This year we had record interest in the #HackAAS event, even after a long week of science and networking. Also watch as I drop things AND forget to turn my camera on... This is the fifth of my daily vlogs from the 233rd meeting of the American Astronomical Society, held in beautiful Seattle in Jan 2019. All week I'll be showing talks, posters, swag, vendors, people, and trying to give a taste of what it's like to attend the largest annual professional astronomy meeting in the world!
