The Princeton ACM is the student chapter of the world’s largest educational and scientific computing society, the Association for Computing Machinery (ACM). The Princeton ACM aims to connect and create a community for Princeton students of all majors interested in computer science. They hold regular events, such as their bi-to-tri-weekly all-night-long Hackathons (“Code@Night”), at CITP on the third floor of Sherrerd Hall. To find out about the next Code@Night, subscribe to their mailing list.
