One way to address the lack of diversity in tech is to expose kids to computer science as early as possible. That's exactly what Ruth Mesfun is doing. She studied how to teach CS, so she could conjure up a curriculum and launch a new class for the Excellence Girls Middle Academy, an all-girls, majority-black middle school in Brooklyn. She has also created a website called "People of Color in Tech" with her developer friend Michael Berhane, so her kids can find role models to look up to. The website features interviews of engineers, designers and other people of color in the industry, and Mesfun and Berhane hope to to add two more profiles every week.
