About HCS

Promoting CS knowledge, fostering the CS community, and offering free resources to Harvard affiliates.

HCS is Harvard College's student-run computer science community. We make technical knowledge easier to access and create places for students to learn, build, and spend time together.

Our history

Part of Harvard's computing community since 1983.

HCS has long supported how students use and learn about technology. The organization once provided infrastructure for Harvard student mailing lists; today, we focus on open resources, events, and community for students interested in computer science.

What we do

Three areas shape the HCS experience.

Academics

We host workshops and faculty talks, share concentration guidance, and make it easier for students to find the courses and resources that fit their interests.

Professional Development

Industry conversations, practical workshops, and access to people working across technology help students explore careers and prepare for what comes next.

Community

Study breaks, mentorship, office visits, and social events give students space to connect beyond the classroom and build lasting friendships.
