When I did start learning, I was amazed by how much was out there: introductory videos, explanatory blog posts, tips and tricks and step-by-step guides. If you're a journalist who wants to make a news app or a student interested in learning to code, you have plenty of paths to choose from.

A little over a month ago, Al Shaw and I made an interactive map of the “Great Migration” of African Americans from the rural south to northern cities during the 20th century. The housing discrimination suffered by African Americans in their new cities led to calls for reforms, resulting in the Fair Housing Act of 1968. But as the fantastic reporting by ProPublica reporter Nikole Hannah-Jones shows, the federal Housing and Urban Development agency has fallen short of its requirement to take affirmative steps to curb segregation in America’s cities and provide fair housing for everybody.
To accompany the story we wanted to make a map showing the Great Migration itself. We also decided early on that it would be the lead art for the article.

Political campaigns send many variations of each email to supporters. We’ve been collecting emails from political campaigns and tracking the variations. You can be a part of this project by forwarding political emails you get to firstname.lastname@example.org.
ProPublica has been collecting political emails for a project we call the Message Machine, with the help of more than 600 readers who have shared demographic information with us and who have so far forwarded us more than 30,000 political emails. The Message Machine identifies and classifies many different emails as different variations of a single email blast, to highlight and analyze the ways in which campaigns use their sizable databases to customize their messages based on what they know about each recipient.
We’ve been publishing our collection for a few months, and today we are publishing the latest results of our analysis. The Machine uses techniques from Natural Language Processing and Machine Learning to analyze every email our readers forward to it.
