Chicago Crime Hack, day one

The Knight Lab hosted its first ever hack day on Saturday and about 15 civic-minded hackers showed up to tinker with the Chicago Tribune’s Chicago Crime API.

A group works at the Knight Lab's Chicago Crime Hack Day.

The day started with a quick round of introductions from a diverse group. Some were professional developers with day jobs building software for trading firms or IBM, while others were self-described apprentices and hobbyists.

No matter, everyone seemed excited about getting to hack on Chicago’s crime data.

 

A few knowledgeable folks gave five-minute lightning talks to get the day started.

  • Joe Germuska gave a quick run down of Chicago’s crime data, explaining that 26 fields of data boil down to four basic concepts: which incident occurred (defined variously by ID and case number), when it occurred (date, time), what crime occurred (assault, theft, narcotic violation, etc.), and where it occurred (ward, community area, block, latitude/longitude, etc.).


By the end of the day a few cool ideas and concepts had emerged.

Adam Pearce demos his filtering tool.

Adam Pearce built a crossfiltering tool that let’s users visualize crime by day of week, time of day, and type. Pearce had started the project before the hack day, and unveiled his site to a few oohs and ahs from the crowd.

(Side note: Pearce appears to be quite the civic hacker. Check out some of his other work.)

The rest of the folks worked on everything from adding data to fusion tables to creating spark lines for homicides.

All in all it was a nice, educational day. The Knight Lab got to meet a few more Chicago programmers and the TribApps team got a few more people using their API. And of course the guidance, brainstorming, and nourishment provided by Source was outstanding.

If you couldn’t make the hack last Saturday, catch one of the next two in Evanston and Pilsen.

    For a few days in October 1993, if you were interested in journalism and technology, Raleigh, North Carolina was the place you had to be. The first Computer-Assisted Reporting Conference offered by Investigative Reporters & Editors brought more than 400 journalists to Raleigh for 3½ days of panels, demos and hands-on lessons in how to use computers to find stories in data. That seminal event will be commemorated this week at the 25th CAR Conference, which...

  • Prototyping Augmented Reality

    Something that really frustrates me is that, while I’m excited about the potential AR has for storytelling, I don’t feel like I have really great AR experiences that I can point people to. We know that AR is great for taking a selfie with a Pikachu and it’s pretty good at measuring spaces (as long as your room is really well lit and your phone is fully charged) but beyond that, we’re really still figuring...

  • Capturing the Soundfield: Recording Ambisonics for VR

    When building experiences in virtual reality we’re confronted with the challenge of mimicking how sounds hit us in the real world from all directions. One useful tool for us to attempt this mimicry is called a soundfield microphone. We tested one of these microphones to explore how audio plays into building immersive experiences for virtual reality. Approaching ambisonics with the soundfield microphone has become popular in development for VR particularly for 360 videos. With it,...

  • Prototyping Spatial Audio for Movement Art

    One of Oscillations’ technical goals for this quarter’s Knight Lab Studio class was an exploration of spatial audio. Spatial audio is sound that exists in three dimensions. It is a perfect complement to 360 video, because sound sources can be localized to certain parts of the video. Oscillations is especially interested in using spatial audio to enhance the neuroscientific principles of audiovisual synchrony that they aim to emphasize in their productions. Existing work in spatial......

    During the Winter 2018 quarter, the Oscillations Knight Lab team was tasked in exploring the question: what constitutes an engaging live movement arts performance for audiences? Oscillations’ Chief Technology Officer, Ilya Fomin, told the team at quarter’s start that the startup aims to create performing arts experiences that are “better than reality.” In response, our team spent the quarter seeking to understand what is reality with qualitative research. Three members of the team interviewed more......

    Our Knight Lab team spent three months in Winter 2018 exploring how to combine various technologies to capture, interpret, and fact check live broadcasts from television news stations, using Amazon’s Alexa personal assistant device as a low-friction way to initiate the process. The ultimate goal was to build an Alexa skill that could be its own form of live, automated fact-checking: cross-referencing a statement from a politician or otherwise newsworthy figure against previously fact-checked statements......
