Hi, I'm Derek Eder. I'm an entrepreneur, developer and one of the leaders of the civic technology community in Chicago. During the day, I run DataMade, a civic technology company.

Introducing Decarb My State

As part of our 500th Chi Hack Night on July 12, 2022, Derek Eder gave a lightning talk debuting, a new website to galvanize action on climate change through clean electrification.

Intro to being anti-racist in civic tech

What does it mean to be anti-racist? What is white supremacy culture and how does it show up? Over the past months, Chi Hack Night’s Diversity, Equity and Inclusion (DEI) committee has discussed and researched these questions. I am joined by fellow Chi Hack Night Board Members Ryan Spencer and Samantha Evans to share what we learned in our blog post so that we can all work to make our communities more equitable and just.

Decarb My State

With volunteers at Chi Hack Night, we pulled together emissions and electrification data for all 50 states + DC and organize it based on the biggest sources of climate pollution: the machines we use to heat our homes, cook our food, get us places, and produce our power. We count and name every coal, gas and oil plant that needs to close, track how many of our buildings and cars have been electrified, and how much wind and solar has been built.

Budget: Oak Park

Budget: Oak Park is a budget transparency tool for the Village of Oak Park, Illinois. It was built by Oak Park Residents Derek Eder (Partner, DataMade) and Alicia Chastain. It is not an official application from the Village. By extracting data from the Village’s official budgets from 2017, 2019 and 2021, we were able to display and compare annual budgets from 2013 through 2021.

2nd City Zoning

To make Chicago’s zoning code digestible by humans, we took inspiration from one of our favorite games: Sim City 2000. Find out how your building is zoned, learn where to locate your business and explore zoning patterns throughout the city. • © 2022 Derek Eder
